when it’s fed more watts? As we discovered in our AMD Ryzen Threadripper 7000 Series review (see page WS8), there can be diminishing returns. Returning to our Nvidia RTX 5000 Ada Generation laptop GPU example, don’t expect to get 44% more graphics performance out of the ThinkPad P16 simply because the GPU has access to 44% more power. The performance curve will always flatten out.

A call for transparency I understand that I may be preaching to the converted. Many of you love workstations even more than me, and a lot of this information is out there in the public domain. But for the average person comparing laptop specs, few would think to search out a processor’s TGP or TDP for a specific machine, which may or may not be hidden in the depths of a technical document somewhere. It would be great to see more transparency from the workstation OEMs. A simple bracketed power consumption figure right next to each processor would be a good start. Power consumption in relation to performance is not always straightforward (read our Nvidia RTX 4000 Ada Generation review on page WS36 to find out why), but it would at least show potential buyers a difference between two machines. Let’s just get the conversation started. Of course, publishing power consumption up front would also draw attention to just how much energy some of these processors consume, which is another conversation entirely. At the end of the day, it’s all about giving people the data they need to make informed decisions, and that’s got to be good for everyone, right?

Know your workstation Greg Corke breaks down the desktop workstation, and explores what key components mean for product design, engineering and manufacturing workflows

Processor (CPU) Always aim for a CPU with a high turbo or boost frequency (GHz). This is important for the performance of the system and of the applications, as many operations are single threaded or lightly threaded. i.e. they use only one CPU core or a handful of cores. Highly multi-threaded operations can take good advantage of multiple CPU cores. Ray trace rendering is the best example, as performance scales very well. Simulation software also tends to be multi-threaded, especially Computational Fluid Dynamics (CFD). With Finite Element Analysis (FEA) there can sometimes be diminishing returns as you use more cores, and performance can even go down. It is sometimes possible to run multiple simulations in parallel on a single machine, providing you have sufficient memory and memory bandwidth, storage bandwidth and software licences. CPUs that have lots of cores typically run at lower frequencies, so it’s important to strike a balance. In saying that, the new AMD Ryzen Threadripper 7000 Series processors are bucking that trend. Another strategy is to optimise your workstation for modelling workflows and send your multi-threaded calcs to a server or the cloud. Intel used to dominate the workstation CPU market, but this has changed. For highend multi-threaded workflows, AMD Ryzen Threadripper or AMD Ryzen Threadripper Pro processors have a clear lead over the Intel Xeon W-Series. However, mainstream Intel Core processors still have the edge over AMD Ryzen in single threaded or lightly threaded workflows, such as CAD and BIM.

Graphics (GPU) The professional 3D graphics card or graphics processing unit (GPU) is one of the key components that defines a professional 3D workstation. Pro GPUs come with pro graphics drivers, which are specifically designed to work with professional 3D software (especially CAD and BIM software). Pro GPUs are often given an official stamp of approval for individual applications through a process called ‘certification’, which comes with the promise of full support from the software developer. Pro graphics drivers can mean better performance, better stability and access to specific features, such as RealView in Solidworks, and Order Independent Transparency (OIT) in several 3D CAD applications. If there are any display or stability issues in your CAD or BIM software, they are more likely to be fixed in a subsequent driver release. Modern GPUs comprise different types of processor cores. Many have hardware ray tracing built in, which is essential for modern visualisation software, for offline rendering and to bring ray tracing effects into viewport. Meanwhile, AI cores can be used to ‘denoise’ renders, or to boost 3D performance in real time applications. Nvidia has the lion’s share of the add-in GPU market with its Nvidia RTX family and older Quadro GPUs. AMD Radeon Pro also plays an important role, especially in terms of price/ performance. Intel is also looking to get in on the action with Arc Pro, which launched last year. Some Intel and AMD CPUs include integrated graphics, but these are currently mainly for entry-level mobile workstations. Professional GPUs are facing increased competition from their consumer counterparts — Nvidia GeForce, AMD Radeon, and Intel Arc. Some of the major workstation OEMs now offer consumer GPUs in their workstations. High-end professional GPUs tend to feature more memory than high-end consumer GPUs, which is a big consideration. However, they can easily compete on raw processing power. For CAD and BIM workflows we recommend sub-£500 entry-level to mid-range pro GPUs with 8 GB or more, but when you get into the high end, an area where you need more 3D performance for real-time visualisation, offline rendering or virtual reality (VR), the difference in price is greater and pro graphics cards are often a harder sell for those on a budget, especially for applications that support multiple GPUs. Nvidia even has a GeForce ‘Studio’ driver for applications including Enscape, Unreal Engine and V-Ray. GPUs are not just for 3D graphics or rendering. They can also be used to solve other parallel processing tasks such as simulation and reality modelling. Some simulation software requires good double precision performance, which is available in specialist GPUs like the Nvidia A800.

Memory (RAM) It’s important that your workstation has enough system memory. If is becomes full, performance can significantly slow down as your workstation has to page data to your Solid State Drive (SSD). Every application you load up uses up memory, so you will need to be able to cover all the applications and datasets you typically have open at the same time — think CAD, visualisation, data management, simulation, email client, web browser, and others. 32 GB is a good starting point for CAD-centric workflows, with 64 GB or more recommended for more demanding workflows such as visualisation, simulation and reality modelling. Memory bandwidth is important, but only to certain workflows. It is governed by the frequency of the memory and the number of memory channels supported by the workstation platform. Mainstream processors like Intel Core and AMD Ryzen generally support dual channel memory, which is fine for CAD, while Intel Xeon W-Series and AMD Ryzen Threadripper (Pro) processors offer 4 or 8 channel memory, which can benefit memory intensive applications like simulation. In order to benefit from the full memory bandwidth, the number of memory modules should match the number of memory channels. Don’t forget that memory requirements will always change over time. Your datasets will get bigger and the memory footprint of your operating system and applications will increase with new releases. With this in mind, it’s good to buy a workstation with spare memory slots for easier upgrades, though this needs to be balanced against memory bandwidth. ECC memory can protect against crashes, which becomes important for lengthy calculations, as you can lose hours of work.

Storage M.2 NVMe Solid State Drives (SSDs) have quickly become the standard in workstations. Now you must choose between PCIe Gen 5.0 SSDs and PCIe Gen 4.0 SSDs. With PCIe Gen 5.0, sequential read/write speeds are superior. Those working with very large datasets, such as point cloud, simulation or video editing, should benefit most. The cost of NVMe SSDs has come down a lot and it’s now feasible to cover all your workstation storage requirements with one or more SSDs. Most tower workstations support multiple SSDs directly on the motherboard. Some workstations provide front-accessible SSDs, while others offer add-in boards that support multiple SSDs. For the fastest performance or protection against data loss, multiple SSDs can be configured in various RAID arrays. For example, RAID 0 (striped, for performance) or RAID 1 (mirrored, for redundancy so, if one drive fails, your data is safe). SSD endurance is another important consideration, particularly if your workflows involve writing huge amounts of data. Simulation and point cloud processing, for example, can produce huge temporary files. Endurance is often defined by TBW or terabytes written, the total amount of data that could be written to the SSD during its life span. Hard Disk Drives (HDDs) still continue to offer the best price per GB, but should absolutely not be used as a primary drive for operating system and applications. They are good for secondary storage, however, and do not impact load / save times of CAD models that much. However, if you need to process large point cloud or simulation datasets, especially if you don’t have enough RAM to hold the dataset entirely in system memory, then NVMe SSDs are always best.

Operating System Microsoft Windows 11 Professional is pretty standard these days in new workstations, but there are many firms that still rely on Windows 10 Professional. There are many reasons why Windows 11 is better, but one of the most important is when you have an Intel Core processor with a hybrid P-Core / E-Core architecture. Windows 10 sometimes assigns processes to the slower Efficient-cores (E-cores), instead of the faster Performance-cores (P-cores), as one would typically desire. In the past, we have observed simulation in Solidworks, recompiling shaders in Unreal Engine and drawing production in Autodesk Inventor to run notably slower because of this. This can be easily ‘fixed’ by changing CPU priority in the excellent third party tool, Process Lasso, but of course, you must first know that the problem exists. You don’t have this issue when running Windows 11. Everything appears to be assigned correctly.

Power usage

Bottlenecks

Power usage has become an even more critical consideration in recent years. Firms have long been aware of their obligation to protect the environment. Now with rising energy costs they are feeling the pinch. The fact is that energy consumption of processors has been rising steadily. Today we have mainstream workstation processors that draw over 250W at peak and high-end GPUs that hit 450W. There are many ways to save power, but choosing the right hardware is arguably the most important. First, consider a power efficient CPU with fewer cores. Intel Core i5 processors, for example, use significantly less power than Intel Core i9 processors, and won’t be that much slower in single threaded or lightly threaded workflows, such as CAD or BIM. Super compact workstations like the Lenovo ThinkStation P3 Tiny offer T suffix Intel Core i5 processors that consume even less power. There are also AMD Ryzen processors which, overall, offer better performance per watt than Intel Core, though they are not as widely available. Second, buy GPUs that are matched precisely to your workflows. If your viz datasets aren’t that complex and you can smoothly navigate your scene with a 70W GPU like the Nvidia RTX A2000, do you really need the 130W Nvidia RTX 4000 Ada Generation? More powerful GPUs might be able to render your scene with more frames per second, but you probably won’t notice a difference. Of course, offline renders will come back faster.

Understanding how your software works and where your bottlenecks occur can help you make informed decisions on workstation purchases. Don’t presume that software developers know how their software performs with different processors. Recommended specs are not always accurate or up to date. Many of the major workstation OEMs offer free workstation tuning software that can monitor resources in real time and over a set period. Other good tools include GPU-Z for monitoring GPU usage, CPU-Z for CPU, HWinfo and Windows Performance Monitor. If you are experiencing slow 3D performance, for example, check to see how much of your GPU is being used. If it’s 100%, then investing in a more powerful GPU would probably help. However, if usage is significantly lower, you could be wasting your money and would be better off buying a CPU with a higher boost frequency. Once you understand where your bottlenecks occur, it can help you assign budget to the correct areas and tailor a workstation for your specific workflows.

e: choosing a workstation OEM

Warranty

The maker

The chassis

Virtually all workstations come with a three-year warranty, but the level of cover can vary considerably between manufacturers. This isn’t just about protecting your investment. In the event of a failure, you need to get your workstation back up and running as quickly as possible and with minimal hassle. A next business day (NBD) on-site warranty is common with workstations from major OEMs. Some custom manufacturers only offer ‘return to base’ as standard or NBD on site for the first year. Having to send away your workstation to be repaired could mean days without its use, which could be catastrophic when on a tight project deadline. Many minor repairs can be done by yourself. Some manufacturers specifically make their workstations easy to service, so customers can be guided over the phone or video call and get themselves back up and running the same day (or the next day if a part needs to be sent out). Other manufacturers state that any repairs or alterations that are carried out by the customer invalidate the warranty, so check with your supplier first. When comparing prices of workstations, make sure you are looking at details of the warranty and not just the specifications of the machine. Warranties can be extended and negotiated, so also bear that in mind.

A common question is whether to buy your workstation from a specialist system builder or a major OEM like Dell, HP or Lenovo. There’s no simple answer, but there are a number of things to consider. Custom manufacturers are more flexible in how machines can be configured and are generally quicker at introducing new technologies. Many such firms overclock their CPUs, which can boost performance. OEMs, on the other hand, spend much more time on R&D to make sure that components work well together and do extensive studies into acoustics, electromagnetic interference and thermodynamics. OEM workstations tend to be more solid and easier to service, particularly as some custom manufacturers try to cut costs by using budget PC chassis. They also have long term availability, so if you find a system / spec that works for your project team, you will probably be able to buy it for several years. Major OEM workstations also go through extensive testing and certification to ensure they work well. Some software developers will not provide full support if you don’t have certified hardware. With custom manufacturers, you are usually just getting the certification of the GPU. Of course, many large architecture or engineering firms will only buy from major OEMs for reasons of support, management or global availability, so the decision is already made.

Workstations are about so much more than just their constituent parts. The chassis can be incredibly important. There are four main points to consider: size, noise, cooling and serviceability. But easy access to things like USB ports, USB charging ports, hot swappable storage or headphone sockets can also make a big difference. Ask yourself the following questions:

•

• •

Will the machine fit on your desk, or will it have to be kept down by your feet? Could it be attached to the back of a monitor? Can it fit in a rack? How many can you fit in a rack? If you need to move it, is it heavy and does it have built-in handles? Are the fans so noisy that they are distracting? Do the fans do their job or will they make the processor throttle? Will the chassis serve you well into the future? Can you expand the system with GPUs, storage or memory (are there free memory slots)? Is it easy to service internal components? If your power supply unit or fans fail, how easy are they to change?

Of course, if you are the type of person that would never dream of getting inside a computer then serviceability is a moot point. Think about the things that matter to you. For some, aesthetics are very important. February / March 2024

workstation special report

he AMD Ryzen Threadripper 7000 Series processors, based on AMD’s ‘Zen 4’ architecture, launched in October 2023 with specifications that were nothing short of breath-taking. The combination of high core counts (up to 96), high clock speeds (up to 5.3 GHz), support for multiple GPUs and lots of high-bandwidth memory, makes them extremely well suited to a variety of demanding pro workflows including visualisation, simulation, reality modelling, AI, and lots more. Workstations based on these powerful multi-core processors are now starting to come to market. And there are plenty to choose from. The big news is that all the major OEMs now offer a Threadripper workstation. Following the lead of Lenovo in 2020 and Dell in 2022, HP is finally on board. Considering that AMD had virtually no presence in the OEM workstation market three years ago, this is a major breakthrough. There are also workstations from specialist system builders like Armari, BOXX, Puget Systems, Scan, and Workstation Specialists, some of which are overclocked to squeeze even more performance out of the multi-core chip. The other big development is that the AMD Ryzen Threadripper 7000 Series comes in two variants: the ‘Pro’ range

(AMD Ryzen Threadripper Pro 7000 WXSeries) and ‘High-End Desktop (HEDT)’ range (AMD Ryzen Threadripper 7000 Series). This is a change from the previous generation ‘Zen 3’ Threadripper 5000 Series processors which were ‘Pro’ only and marks a return to the dual product family approach of ‘Zen 2’. Splitting out Threadripper into two product families gives users more choice and makes the Threadripper platform more accessible in terms of price. While the Pro and HEDT versions are very similar in terms of clock speed and cache, Pro offers more cores (up to 96 versus up to 64), more memory bandwidth (8-channels versus 4-channels of DDR5), more PCIe lanes, and comes with AMD Pro Security and Manageability. Management and security are critical for enterprises, which is why the major OEMs only offer workstations with Threadripper Pro. Meanwhile, specialist systems builders can offer both, although we suspect most of their workstations will be sold with HEDT processors. The platform is not only cheaper, but there are only select workflows that will benefit from the additional memory bandwidth of Pro. Some engineering simulation solvers, including computational fluid dynamics (CFD), will. Many visualisation workflows, including rendering, will not.

The ‘Zen 4’ generation AMD hasn’t released an HEDT Threadripper since 2020, so it’s fair to say that both new ‘Zen 4’ Threadrippers are the natural successors to the ‘Zen 3’ Ryzen Threadripper Pro 5000 WXSeries, which launched in 2022. Let’s look at where things have improved. Core count: Threadripper Pro 5000 WXSeries maxed out at 64-cores, but the new Threadripper Pro 7000 WX-Series goes all the way up to 96-cores. This alone will deliver a substantial performance improvement in highly multi-threaded workflows such as ray trace rendering and engineering simulation. Meanwhile, the ‘HEDT’ Threadripper 7000 Series peaks at 64-cores. Higher frequencies: Base and boost frequencies on all Threadripper 7000 Series chips are significantly higher than the Threadripper 5000 WX-Series. This benefits everyone – those with highly multi-threaded workflows such as rendering and those with single threaded workflows such as CAD. Both the 64-core Threadripper Pro 7985WX and Threadripper 7980X processors, for example, deliver 3.2 GHz base and 5.1 GHz boost, which is 0.5 GHz and 0.6 GHz faster than their ‘Zen 3’ equivalent, the Threadripper Pro 5995WX.

Even the top-end 96-core Threadripper Pro 7995WX delivers a whopping 5.1 GHz boost, which is only 0.6 GHz behind AMD’s top-end consumer processor, the 16-core AMD Ryzen 9 7950X. These significant frequency gains are in part down to an increase in Thermal Design Power (TDP), going from 280W in the previous generation to 350W for all new Threadripper 7000 Series chips.

Higher IPC: All Threadripper 7000 Series chips get a significant boost simply because they are built on AMD’s newer Zen 4 architecture. Compared to Zen 3, AMD quotes a 13% uplift in Instructions Per Clock (IPC), the number of instructions a CPU can execute in a single clock cycle. This should benefit all multicore and single core workflows.

on the number of memory channels. Here the Threadripper Pro 7000 WXSeries has an advantage over the ‘HEDT’ Threadripper 7000 Series as it supports eight channels versus four, although all RDIMM slots need to be populated in order to benefit. The previous gen Threadripper Pro 5000 WX-Series also supports 8-channels, but consumer processors including the AMD Ryzen 7000 Series and 14th Gen Intel Core, support dualchannel DDR5. Incidentally, AMD decided not to go for 12-channel memory, a hallmark of its Zen 4 EPYC server processors. According to AMD, this is partly to tailor the platform to a workstation audience and partly because there is simply no room for more RDIMM slots in a standard workstation chassis.

With 148 PCIe lanes (128 of which are PCIe Gen 5.0), the Threadripper Pro 7000 WX Series platform can, in theory, support eight double slot GPUs. In reality, this number is less, as it’s decided by the motherboard manufacturers. Most of the major workstation OEMs support two or three double slot GPUs on their new Threadripper Pro machines, but we could see boards from specialist manufacturers that support more. This could be an interesting proposition for manufacturers of virtual workstations who want to assign a powerful dedicated GPU to each virtual machine. Meanwhile, the ‘HEDT’ Threadripper 7000 Series supports 92 PCIe lanes (48 PCIe of which are 5.0). PCIe lanes can also be used for high-performance storage and network cards.

DDR5 memory: Both Threadripper 7000 Series chips support 5,200 MHz server-class DDR5 RDIMM memory, compared to 3,200 MHz DDR4 with the 5000 WX-Series. DDR5 memory delivers significantly more bandwidth, which will benefit some memory intensive workflows such as engineering simulation. Memory bandwidth is also dependent

PCIe Gen 5: The new Threadripper 7000 Series supports PCIe Gen 5, which doubles the PCI bandwidth to any slot on the board compared to the previous generation with PCIe Gen 4. According to AMD, this should deliver real benefits to multi-GPU AI workflows. But this is more for the future, as current pro GPUs, including the Nvidia RTX 6000 Ada and AMD Radeon Pro W7900, are still on PCIe Gen 4.

AVX-512 instructions: The new ‘Zen 4’ Threadrippers support AVX-512, a set of extensions to the x86 instruction set that are used to boost performance in a variety of software tools. AVX-512 is especially prevalent in simulation software, with supported applications including Altair Radioss, Simulia Abaqus and Ansys Mechanical. AVX-512 was originally developed by Intel and is supported on

Xeon processors, so this is a big step up for AMD. It is not supported on Intel Core processors with a hybrid P-Core / E-Core architecture.

The new chips The new ‘Zen 4’ Threadrippers present users with more choice than ever. There are six models in the Threadripper Pro 7000 WX-Series chips with 12, 16, 24, 32, 64 or 96 cores, and three models in the ‘HEDT’ Threadripper 7000 Series with 24, 36 or 64 cores. All eyes are on the flagship AMD Ryzen Threadripper Pro 7995WX. With 96-cores and a boost frequency up to 5.1 GHz this monster chip is head and shoulders above AMD’s previous flagship workstation processor, the 64core Threadripper Pro 5995WX, and indeed the competition. Intel’s top-end workstation chip, the 56-core Intel Xeon w9-3495X, lags behind in both single threaded and multi-threaded workflows. Of course, for unrivalled performance, AMD can charge a big premium, and many firms will find the 96-core chip’s price tag of £8,250+VAT hard to swallow, especially considering the performance uplift over the 64-core model is not always that big (see later). Better value can be found with the lower core-count models, especially with the HEDT Threadrippers. At £4,125+VAT, for example, the 64-core AMD Ryzen Threadripper 7980X costs around 50% less than the 64-core Threadripper Pro 7985WX. In terms of price per core, the 24-core AMD Ryzen Threadripper 7960X looks best value. And at £1,242+VAT it’s nearly half the price of its Pro equivalent, the AMD Ryzen Threadripper Pro 7965WX. The challenge for these lower end Threadripper 7000 Series processors is demonstrating enough value when compared to the AMD Ryzen 9 7000 Series. These consumer-focused processors, which peak at 16-cores with the Ryzen 9 7950X and Ryzen 9 7950X3D, are significantly cheaper, as are the motherboards that support them. While the jump from 16 to 24 cores is not that big, the Threadripper 7000 Series offers much more than just more cores. There’s more memory capacity, more memory bandwidth, and more PCIe lanes, which will be important for some customers.

All about the power All AMD Ryzen Threadripper 7000 Series processors are rated at 350W Thermal Design Power (TDP). TDP is www.develop3d.com

a measure of the maximum power a chip will consume under the maximum theoretical load. This is 70W higher than the previous generation Threadripper Pro 5000 WX-Series, so presents some significant thermal challenges for workstation manufacturers. To keep the processor within its thermal limits and stop it from overheating (and therefore throttling) workstation manufacturers have two options: air cooling or liquid cooling. Air cooling uses fans to blow cool air over a heatsink that is attached directly to the CPU via a conductive baseplate and heat pipes. This method is preferred by the major workstation OEMs as it’s considered to be the most reliable. Liquid cooling uses a liquid coolant, which flows from the baseplate through a tube to a large heat exchanger cooled by fans. It’s a more efficient way of removing heat from the CPU, but because there are more points of failure (and liquid involved), it’s considered to be more of a specialist solution. It is not offered by the major OEMs. Liquid cooling has two potential benefits: first, the workstations can sometimes be quieter as fans don’t have to work as hard, and second, the best liquid coolers allow more power to be pumped into the CPU so boost clock speeds can remain higher for longer. With the AMD Threadripper 7000 Series processors (HEDT and Pro) more power can be applied through a technology called Precision Boost Overdrive (PBO). It isn’t the same as traditional overclocking, where specialists manually tweak CPU frequency and voltage. With PBO, the boost is essentially automated without losing stability. By simply changing a setting in the motherboard BIOS or AMD Ryzen Master software, the CPU can be fed more power as long as the cooler can handle it. PBO is not enabled on any workstation from the major OEMs, so 350W is the maximum power that is ever pumped into the CPU, regardless of the number of cores. As all Threadripper 7000 Series processors have the same TDP, it means the higher core count CPUs have lower all core frequencies. This presents an opportunity for specialist system builders like Armari to take power and performance beyond the standard levels. Using a custom All-In-One (AIO) cooler, Armari raises the sustained PBO to around 700W, delivering higher clock speeds over a longer period of time to get significantly

more performance out of the same silicon, all while keeping within thermal limits so the processor is not throttled. The conundrum for specialist system builders is that of warranty. While AMD makes overclocking easy and safe with PBO, and actively promotes the practice with a crack team that uses liquid nitrogen to break world records, the official stance is that AMD’s product warranty does not cover damages caused by overclocking. When you are talking about processors that costs thousands of pounds this is a big exposure for a specialist system builder. In the case of Armari, it has a tonne of experience in boosting workstations while keeping machines running within safe limits. It has stated that PBO tuning will be a ‘supported and fully warrantied feature’ of its flagship Magnetar M64T7 workstation.

drop in frequency which would reduce performance in workflows that do not benefit from additional cache.

A lot of what we see in the Threadripper 7000 Series is inherited from AMD’s ‘Zen 4’ EPYC server processors. Some of the more recent models from the EPYC 9004 Series come with 3D V-Cache, a special type of L3 cache that is stacked vertically instead of horizontally, so more cache

can be placed on the CPU. The 96-core AMD EPYC 9684X, for example, boasts a whopping 1,152 MB compared to its non 3D V-Cache equivalent, the AMD EPYC 9654 which has 384 MB. The benefit of having more cache is that the CPU has a greater chance of being able to fetch the data it needs from faster cache instead of from slower system memory (RAM). And in some memory intensive workflows, such as CFD, where large amounts of data need to be fetched regularly, this can deliver a performance benefit, as demonstrated in DEVELOP3D’s review of the consumerfocused AMD Ryzen 7000 X3D processor, and in this blog post about CFD software Siemens Simcenter STAR-CCM+ (www.tinyurl.com/Epyc-siemens). None of the new Threadripper 7000 Series processors support 3D V-Cache. Instead, chips come with standard L3 cache, up to 384 MB on the 96-core model. On a core-to-core basis this is the same as the previous generation. AMD said that it experimented with 3D V-Cache on Threadripper but found that there are ‘very few applications that show a material performance uplift’. Enabling 3D V-Cache also means a small

we also tested with ‘Level 3’ (70°C – around 500W), ‘Level 1’ 90°C (around 700W) and with PBO off (350W). To put these temperatures into perspective, AMD considers 95°C to be safe ‘with no detriment to longevity or reliability’. For reference, when rendering in Cinebench 23 for one hour, the HP Z6 G5A hit 95°C and the Lenovo ThinkStation P8 hit 83°C, although it mostly hovered around 75°C. There are also some differences in memory. For the ‘Zen 4’ Threadrippers, memory officially goes up to 5,200MT/ sec. The HP Z6 G5A uses eight 16 GB RDIMMs of 5,200MT/sec memory, making full use of Threadripper Pro’s eight memory channels. It topped the charts in the SiSoft Sandra benchmark with a score of 206.1 GB/sec.

AMD Ryzen Threadripper Pro processors feature up to 96-cores

For pure rendering, the performance uplift from the 32-core 7970WX to 64core 7980X was larger: V-Ray (63%), KeyShot (56%), Cinebench 23 (52%), Cinebench 2024 (58%). Despite having 100% more cores, you don’t get double the performance, as the 32-core 7970WX can sustain a higher all-core frequency (4.39 GHz vs 3.56 GHz in Cinebench 23). Interestingly, the 32-core 7970WX edges out the 56-core Intel Xeon w93495X and the 96-core 7995WX edges out the dual 60-core Intel Xeon Platinum 8490H. It looks like Intel will find it very hard to compete with AMD, although Intel could go hard on price/performance. Next, we brought PBO into mix with the Armari Magnetar M64T7. This massively upped the power consumed by the 64-core 7980X processor but yielded some very fast results. The maximum ‘Level 1’ 90°C profile pushed peak power consumption to around 700W but saw performance rise by as much as 28% with both V-Ray and KeyShot. Remarkably, when drawing up to 700W, the 64-core 7980X even outpaced the 96-core 7995WX with the standard 350W TDP. It’s important to note that there are diminishing returns as you pump more power into the processor. With this in mind, it looks like the 70°C profile, which ‘only’ raises the power draw by 150W, might deliver the best balance.

an important part of many design, engineering and architecture workflows. In years gone by the trade-off of having lots of cores, meant low frequencies and limited performance in tools like Revit, Solidworks and Inventor, when compared to mainstream desktop processors with far fewer cores. This started to change with first generation Threadripper and now the Threadripper 7000 Series takes single threaded performance to new levels. The 32-core 7970WX and 64-core 7980X hit 5.0 to 5.1GHz, while the 96core 7995WX reached 4.7 GHz, delivering impressive scores in the SPECapc for Solidworks 2022 benchmark. This is a fair bit ahead of the previous generation AMD Threadripper Pro 5995WX (64 C) and not that far behind the best consumer processors – 14th Gen Intel Core and AMD Ryzen 7950X. PBO made no difference to performance.

Simulation performance Engineering simulation includes Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD). FEA can help predict how a product reacts to real-world forces or temperatures. CFD can be used to optimise aerodynamics in cars or predict the impact of wind on buildings. Both types of software are extremely demanding computationally. There are many different types of ‘solvers’ used in FEA and CFD and each behaves differently, as does each dataset. In general, CFD scales very well and studies should solve much quicker with more CPU cores. Importantly, CFD can also benefit greatly from memory bandwidth, as each CPU core can be fed

data quicker. This is one area in which Threadripper Pro 7000 WX-Series has a potential advantage over the ‘HEDT’ Threadripper 7000 Series as it supports 8-channel memory compared to 4-channel. For testing we used three select workloads from the SPECworkstation 3.1 benchmark. These included two CFD benchmarks (Rodinia, which represents compressible flow, and WPCcfd, which models combustion and turbulence) and one FEA benchmark (CalculiX, which models a jet engine turbine’s internal temperature). We decided not to publish any results from Rodinia benchmark as they were very inconsistent with the 64-core and 96-core Threadripper processors. However, one thing that remained clear is that the dual Intel Xeon Platinum 8490H (2 x 60 cores) had a considerable lead. As we’ve seen before, the WPCcfd benchmark is very sensitive to memory bandwidth. With the 32-core HP workstation having almost double the memory bandwidth of the 96-core 7995WX Lenovo workstation, it came out top in this test. Lenovo shared some internal lab results from the WPCcfd benchmark which put the 96-core 7995WX with 8 x 32 GB RDIMMs in at 22.43. While this would give it top spot, it’s not a convincing argument for spending so much more on a 96-core processor. On the flip side, memory bandwidth has very little impact in the Calculix (FEA) benchmark, so the 96-core Threadripper won out. The 32-core 7970WX beat the 56-core Intel Xeon w9-3495X in both tests. Surprisingly, any benefit from PBO was negligible. This is because the benchmarks don’t appear to stress the CPU anywhere near as much as ray trace rendering, which takes full advantage of AMD’s Simultaneous Multi-threading (SMT), allowing each CPU core to handle two tasks (threads) at the same time - CPU resources that would otherwise be idle. In the WPCcfd test for example, even with the maximum ‘Level 1’ 90 C profile and all 64-cores running flat out, the temperature of the CPU never went above 81 C, drawing 447 Watts at peak, and maintaining a phenomenal 4.73 GHz on all 64 cores for the duration of the 48-minute test. When PBO was disabled and power draw went down to 350W, frequency fluctuated between 4.32 GHz and 4.52 GHz. However, this drop in clock speed appears to have little impact on performance. In short, when overclocking in these simulation workloads, you could simply be wasting power. www.develop3d.com

We wouldn’t describe it that way, but fan noise was perfectly acceptable, with both the Threadripper Pro 7975WX processor and Nvidia RTX A6000 GPU in our test machine running flat out. Temperature on the 7975WX hit 95°C when rendering on all 32 cores. This is significantly higher than the other Threadripper 7000 Series workstations we’ve tested, and right on the CPU’s maximum recommended operating temperature. It might be the case that not all Threadripper Pro processors hit this temperature limit inside the HP Z6 G5 A. Although it sounds counter-intuitive, the 32-core model is reportedly harder to cool than the 64-core and 96-core models as it has fewer chiplets, so the power (and therefore heat) is concentrated in smaller areas. N.B. Instead of being made from a single large piece of silicon, Threadripper 7000 Series processors are made up of multiple 8-core chiplets (also called CCDs), which are then stitched together. With such a compact chassis, HP has worked hard on customisation. Rather than using up an additional PCIe slot, a proprietary Flex-IO interface at the rear enables the user to expand connectivity, adding 10GbE RJ45 LAN (in addition to the standard 1GbE Ethernet built in), Wi-Fi6, which hooks into the internal integrated antenna, or more USB ports. As standard, the machine has no USB Type-C ports, so you’ll either need to use up the Flex-IO expansion at the rear or go for the premium front I/O option of (1) www.develop3d.com

In this day and age, and considering that workstations typically remain in service for years, it seems strange not to make USB Type-C standard, especially as using up the Flex-IO expansion can restrict other customisation options. Finally, there’s also an optional HP Dual Port Thunderbolt 4 Low Profile PCIe add-in card, offering data transfer rates of up to 40Gb/s.

HP Z in the datacentre In recent years, HP has made a big play for its desktop workstations to be deployed in datacentres and server rooms as a centralised, remote resource. The HP Z6 G5 A is 4U in size and comes with an optional rack mount kit, and optional HP Anyware Remote System Controller. This PCIe add-in card is designed to give the workstation ‘server level’ management capabilities. The idea is to help IT managers better manage fleets of workstations, allowing them to remote in, power workstations on and off remotely, perform bare metal imaging (with multiple Operating Systems), manage inventory, and get hardware alerts and diagnostics info. Then, of course, there’s HP Anyware, the remote access and collaboration software which evolved from HP’s

acquisition of Teradici in 2021. Altogether, it gives HP a joined-up solution to support the growing shift towards hybrid working.

Performance Our HP Z6 G5 A test workstation came with the mid-range 32 core AMD Ryzen Threadripper Pro 7975WX processor. While this only gave the machine one third of its potential maximum number of cores, it offered a good insight into how performance scales within the family of processors and of the broader benefits of the Threadripper Pro platform. The first thing to note is that compared to the top end consumer AMD Ryzen 9 7950X processor with sixteen ‘Zen 4’ cores it delivered around 60% to 70% more performance in our ray trace rendering benchmarks. This is nothing to be sniffed at, but it’s in memory bandwidth intensive workflows, such as Computational Fluid Dynamics (CFD), that the HP Z6 G5 A and its Threadripper Pro processor truly shines. With the 8-channel memory architecture fully harnessed with 8 x 16 GB DIMMs, it outperformed the dual channel AMD Ryzen 9 7950X3D processor in the SPEC Workstation 3.1 WPCcfd workset benchmark by more than a factor of three. In the WPCcfd test, superior memory bandwidth even gave it the edge over the Lenovo ThinkStation P8 with a 96core Threadripper Pro 7995WX Series processor. The ThinkStation P8 we tested February / March 2024

only had four RDIMMs fitted, so the HP Z6 G5 A made the most of having almost double the memory bandwidth (113.86 GB/sec vs 206.1 GB/sec). In ray trace rendering, more cores means more performance, and here the ThinkStation P8 with 96 core 7995WX has a clear lead. But as the number of cores goes up, the all-core frequency goes down, so you get closer to double the performance when going from 32 to 96 cores, despite having three times as many. And then there’s Intel’s single socket workstation processor, the Intel Xeon W-3400. Amazingly, the HP Z6 G5 A with a 32 core Threadripper Pro 7970WX, edged out a Lenovo ThinkStation P7 configured with the top-end 56 core Intel Xeon w9-3495X in all our benchmarks — multi-threaded and single threaded. With this in mind, it’s hard to see where the original Intel-based HP Z6 G5 workstation fits in unless it wins out at certain levels of price/performance.

The verdict Considering its size, the HP Z6 G5 A is a remarkably powerful workstation. It’s solid, extremely well built and the smallest Threadripper Pro OEM workstation out there, edging out the Lenovo ThinkStation P8 and Dell Precision 7875 Tower. But in its drive to keep things compact, it feels like HP has made some tradeoffs. If connectivity or multi-GPUs are important, then it’s prudent to fully explore if this chassis will work for you — now and in the future. These small points shouldn’t detract from an otherwise excellent workstation. With support for Threadripper Pro 7000 WX-Series processors from 12 to 96 cores, it can hit so many different workflows. It’s hard to see how HP’s Intel Xeonbased workstations — the HP Z6, Z8 and Z8 Fury G5 — will now get a look in, in anything other than edge case scenarios. A final mention should go to the datacentre. While the HP Z6 G5 A looks like a desktop workstation and performs like a desktop workstation, HP is putting all the pieces in place — hardware and software — to make it an important part of a cohesive remote workstation solution. With the Threadripper Pro 7000 WX Series offering high frequencies and high IPC for good single threaded and multi-threaded performance it shouldn’t have the performance trade-off which many virtualised / cloud workstations suffer from.

Review: Armari Magnetar M64T7 This AMD Ryzen Threadripper 7000 Series workstation takes performance to entirely new levels with a custom liquid cooler that allows to processor to boost well above its typical all core frequencies, writes Greg Corke

ne of the advantages of buying a workstation from a specialist system builder is that they sometimes squeeze every last drop of performance out of key components. This is especially true with CPUs. One of the best in the business is UK firm Armari, which has developed exceedingly powerful workstations for decades and, as we found in our last two reviews, knows how to get the absolute best out of AMD’s multi-core Ryzen Threadripper processors. For its new ‘Zen 4’ Threadripper 7000 Series workstation, the Magnetar M64T7, Armari has managed to significantly increase the performance of a standard Threadripper processor — so much so that an overclocked 64-core High End Desktop (HEDT) model, the AMD Ryzen Threadripper 7980X, can beat a standard 96-core AMD Ryzen Threadripper Pro 7995WX in some workflows. Before we get into the details, let’s first talk about overclocking in general. In years gone by, Armari had to manually tweak frequencies and voltages to boost

Going from PBO off, and running downside to extracting more performance the CPU at a stock 350W, to ‘Level 3’ 70°C, which pumps 150W more into the processor, took all core frequency from 3.56 GHz to 4.10 GHz and boosted performance by 16% in Cinebench R23, 14% in Cinebench 2024, 20% in V-Ray, and 23% in KeyShot. If you’re planning on rendering out a complex animation for hours this is a massive potential time saving. You can take performance even higher but there are diminishing returns with each new Level of PBO. Going from ‘Level 3’ 70°C to ‘Level 1’ 90°C took all core frequency from 4.10 GHz to 4.56 GHz and boosted performance by an additional 7% in Cinebench R23, 6% in V-Ray, and 4% in KeyShot, but you burn a considerable 200W to get you there. We also observed no benefit at all in Cinebench 2024, which uses the Redshift rendering engine. Of course, even small boosts are important to some users and with ‘Level 1’ 90°C enabled the Armari Magnetar M64T7 even outpaced the leader of the ‘Zen 4’ pack, the 96-core Threadripper Pro 7995WX, in all our ray trace rendering benchmarks, as tested in the Lenovo ThinkStation P8.

workstation special report

twice as much as the 64-core 7980X this is certainly food for thought. In fact, you can buy the entire Armari workstation for only a tad more than the 96-core processor. PBO is not for everyone. In some workflows there is no benefit at all. In engineering simulation, for example, in the WPCcfd (Computational Fluid Dynamics) and Calculix (Finite Element Analysis) worksets from the SPECworkstation 3.1 benchmark, scores remained static even with more power draw. There is also no benefit to PBO in single threaded or lightly threaded workflows, such as those typically used in CAD and BIM application like Solidworks and Revit, but at least you are not wasting energy if PBO is enabled, as it never goes above 350W. As reviewed, the Armari Magnetar M64T7 can be considered more of a technology demonstration / preproduction unit than a fully shipping product. When we tested the workstation in December 2023 as part of AMD’s Threadripper 7000 Series review program, Armari was putting the finishing touches to the machine, and in the process of introducing an updated chassis. As part of the review program, AMD provided Armari with 128 GB of G.SKILL Z5 Neo DDR5 6,400 MT/sec memory. Spread across four 32 GB RDIMMs it maxes out the four-channel architecture of the HEDT Threadripper 7000 Series platform. The G.SKILL Z5 Neo DDR5 6,400 MT/ sec memory is not only faster than the typical 5,600 MT/sec DDR5 memory that Armari would supply with this machine, but it also costs significantly more. In fact if you specify 256 GB of 5,600 MT/sec DDR5 memory instead of 128 GB of G.SKILL Z5 Neo DDR5 6400 you’ll save £100. In the Threadripper 7000 Series all memory operates at 5,200 MT/s speeds by default, but like the processor itself, memory can be overclocked. In the Magnetar M64T7, Armari set the memory to run at full 6,400 MT/s memory speeds, delivering a significant boost in memory bandwidth. With a score of 152.15 GB/sec in the SiSoft Sandra benchmark, it wasn’t that far off a Threadripper Pro 7000 WX-Series workstation with 8-channel memory. As tested with 8 x 16 GB DDR 5600 DIMMs (running at 5,200 speeds), the HP Z6 G5A delivered 206.1 GB/sec. Memory bandwidth has very little bearing on performance in ray trace rendering software. However, there are some select visualisation workflows where it will make a difference. Recompiling shaders in Unreal Engine is one, which is probably why the Armari www.develop3d.com

WS24_25_D3D_FEBMARCH24_Armari2.indd 25

Magnetar M64T7 outpaced the Lenovo ThinkStation P8 with the 96-core 7995WX and four 4800 DDR5 RDIMMs (113.86 GB/sec) even with PBO off. We explore performance in much more detail in our in-depth review of the Threadripper 7000 Series, both Pro and High-End Desktop (HEDT) models on page WS8.

The chassis Unlike most other specialist system builders, Armari designs its own chassis. Our test machine was built around the company’s M60G3 case, which features a strong steel frame and lightweight aluminium side panels. It’s since been updated to a G4 edition, with changes largely made to accommodate very high-end Nvidia GPUs. This includes a new ATX 3.0 PSU with native 12VHPWR (Nvidia) GPU power connectors, improvements to the cooling to support two Nvidia RTX 4090s, and a new support brace to secure them in transit. The Armari M60G3 chassis is sizeable. At 470 x 220 x 570mm it’s much bigger than the Threadripper Pro 7000 WX-Series workstations from Dell, HP and Lenovo. A large part is taken up with the AIO cooler’s heat exchanger, which is secured top left and cooled by three 12cm fans. Each memory bank has its own custom RAM cooler, which is 3D printed in house by Armari. The rest of the machine is all about pushing air from front to back using a combination of large Phantek and Noctua intake and exhaust fans. Altogether it contributes to a relatively quiet system, although fan noise does ramp up as PBO levels increase. But even when 700W is being pushed through the CPU, it’s not excessive. There are plenty of options for storage. Armari included a single 2TB Crucial T700 PCIe Gen 5 SSD, but the motherboard can accommodate up to two more M.2 NVMe SSDs (1 x PCIe Gen 5 and 1 x Gen 4). With a caddy for up to four 3.5inch Hard Disk Drives (HDDs) there’s plenty of options to build on this. For accessible I/O, all the ports are on

the top of the machine, rather than the front, which is good or bad depending on where you keep your workstation. There’s (1) USB 3.2 Gen 2 Type-C and (2) USB 3.2 Gen 1 ports. At the rear, you get (1) USB 3.2 Gen2 Type-C, (6) USB 3.2 Gen2 Type-A, and (2) USB 2.0. As the name of the motherboard suggests, the machine has WiFi 6E built in. Of course, for most workstations of this type, it’s all about maximum and consistent data transfer over the network, and this is done via the built in 10Gb or 2.5Gb Ethernet. Armari did not provide a GPU, but we tested with a mid-range AMD Radeon Pro W7700 (16 GB) (see page WS30 for our review). As mentioned earlier, it can take up to two super highend Nvidia GPUs.

The verdict It’s impossible not to take notice of the Magnetar M64T7, simply because Armari has squeezed so much additional performance out of the already powerful Threadripper 7000 Series processor. Dell, HP and Lenovo simply can’t compete on performance alone. Outpacing the 96-core Threadripper Pro 7995WX processor with the 64-core Threadripper 7980X is a phenomenal feat. It can save you a lot of money or, because Armari can also configure this machine with the 96-core Pro chip, there’s potential to take performance even higher. Of course, dialling up PBO does come with a cost — both in terms of power consumed and heat produced. We expect most users will choose some middle ground here. Armari ships the machine with ‘Level 2’ enabled, but customers can select whichever profile they prefer, including PBO off. It’s not inconceivable that a user could temporarily invoke ‘Level 1’ when on a tight deadline, although this will require a reboot. In summary, Armari has delivered another excellent Threadripper workstation that not only stands out from the major OEMs, but many of the other specialist system builders as well.

A NEW ERA OF LAPTOP GRAPHICS The AMD Ryzen PRO 7000 Series processor, at the heart of the HP ZBook Firefly G10 A and HP ZBook Power G10 A, looks set to change the way designers and engineers think about integrated graphics

or 3D CAD, designers and engineers have historically been best served by mobile workstations with a separate CPU (Central Processing Unit) and GPU (Graphics Processing Unit). Processors with integrated graphics have often come up short in terms of raw 3D performance, support for application-specific optimisations, and CAD software certifications. In the case of Solidworks, graphics processors that are not certified do not support certain features, such as RealView for advanced real time shading. The AMD Ryzen PRO 7000 Series processor, at the heart of the HP ZBook Firefly G10 A and HP ZBook Power G10 A, looks set to change the way designers and engineers think about integrated graphics. The top-end AMD Ryzen 9 PRO 7940HS processor, for example, features powerful AMD Radeon 780M graphics that delivers a smooth interactive viewport experience in Solidworks, even when working with large assemblies. This is in part due to raw graphics performance, thanks to AMD’s advanced RDNA3 graphics architecture, but also

because HP has dedicated up to 4 GB of system memory specifically for graphics in these HP ZBook mobile workstations. As both laptops support up to 64 GB of total system memory, this is still a relatively small proportion of the overall memory footprint.

on the GPU. These include Ambient Occlusion, for more realistic shadows; Anti-Aliasing, for smoother edges; Order Independent Transparency (OIT), for faster and more accurate transparent objects; and Occlusion Culling, which means objects that are obscured by others are not rendered. By dedicating up to 4 GB of memory specifically for graphics, the HP ZBook Firefly G10 A and HP ZBook Power G10 A allow more information to be buffered on the GPU. This means less time is spent waiting for the CPU to feed in data, resulting in much better performance. To provide some context, the complex 2,000 component Solidworks motorbike assembly HP ZBook mobile workstations, pictured left uses 4 GB of dedicated powered by the AMD Ryzen PRO GPU memory when viewed in the shaded 7000 Series processor, can handle large Solidworks assemblies with edges display mode at 1,920 x 1,200 resolution.

Review: Workstation Specialists WS IC-Z7900 (14th Gen Intel Core)

he 14th Gen Intel Core processor has received a lot of bad press since its launch in Autumn 2023. The mainstream chip has been criticised for being little different to 13th Gen Intel Core, both architecturally and in terms of performance. Many said it’s not deserving of a new generation. That might be true, but the fact remains that it’s still the fastest desktop processor for single threaded CAD and BIM workflows. If you rely on Revit, Inventor, Solidworks, or other similar tools, you should be paying attention. The WS IC-Z7900 is a mid-sized tower workstation, one of the many to feature the new processor. It’s built around the compact Asus Prime Z790-P WiFi ATX motherboard, which feels a little lost inside the spacious 469 x 220 x 490mm Antec P20CE case, which can take motherboards up to E-ATX (Extended ATX) in size. The workstation has plenty of options for connectivity. At the rear you get a 2.5 Gigabit Realtek RJ45 network port, Dual Band Intel WiFi 6 Network & Bluetooth 5.2, (4) x USB 2.0 Type-A, (2) USB 3.2 Type-A and (1) USB 3.2 Type-C. The easy access ports are located on top, and this also aids uninterrupted airflow from front to back. These include (2) USB 3.0 Type A and (1) USB 3.2 Type-C. There’s 64 GB (2 x 32 GB) of 5,200MHz

Dual Channel DDR5 memory and a lone 2TB Samsung 990 PRO M.2 NVMe SSD. With a slender single slot Nvidia RTX 4000 Ada Generation GPU and no hard disk drives, it’s a very neat build, with minimal visible wires. There are some nice touches inside, including a custom 3D printed mounting bracket attached to the end of the GPU to keep it firmly in place. A large part of the interior is taken up by the Fractal Lumen AIO cooler, which keeps the Intel Core i9-14900KF processor running cool. Despite drawing 253W at peak with its 8 P-Cores and 16 E-Cores running flat out when rendering, CPU temperature never went above 80°C in our tests. The fans kick in after a while, but the machine stays remarkably quiet. The Intel Core i9-14900KF processor sits at the top of Intel’s 14th Gen stack, alongside the slightly more expensive Intel Core i9-14900K, which has integrated Intel UHD Graphics 770 graphics built in. It shines in CAD and BIM workflows, where most operations are single threaded or lightly threaded. However, in the majority of the SPECapc for Solidworks 2022 benchmark tests it only edged out the Intel Core i9-13900K by around 2% to 4%, as tested in the Scan 3XS GWP-ME A132C workstation we reviewed in November 2022. This can be explained by the Intel Core i9-14900KF only having a slightly higher max turbo frequency than

the Intel Core i9-13900K — 6.0 GHz versus 5.8 GHz. Interestingly, the Intel Core i9-13900K beat the Intel Core i9-14900KF in all our multithreaded rendering benchmarks, by as much as 6% in some tests. This can be explained by higher all-core frequencies. In Cinebench R23, for example, the Intel Core i9-13900K hit 4.77 GHz, while the Intel Core i914900KF settled at 4.70 GHz. Of course, as both processors were tested in entirely different systems with different Windows 11 builds, there are many variables here. The lower all core frequency of the Intel Core i9-14900KF could be down to the cooling in the Workstation Specialists machine, rather than the processor itself, although the Fractal Lumen AIO is a respected piece of kit. Compared to the Intel Core i912900K, as tested in the Lenovo ThinkStation P360 Ultra, the performance gains were larger, between 13% and 29% in the single threaded and lightly threaded workloads of the SPECapc for Solidworks benchmark. However, as the Intel Core i9-12900K also has fewer cores (8 P-Cores and 8 E-Cores), the Intel Core i9-14900KF pulled away considerably when rendering. In KeyShot it was nearly twice as fast. Of course, these days Intel faces increased competition from AMD, from both the AMD Ryzen 9 7950X and AMD Ryzen 9 7950X3D processors.

And not just in terms of performance; both AMD chips consume less power. The Core i9-14900KF was around 7% to 12% faster than the AMD Ryzen 9 7950X in most single threaded and lightly threaded operations, as tested in the Scan 3XS GWPME A132R. However, it lost out in most multi-threaded rendering tests. In V-Ray, the AMD Ryzen 9 7950X had a 15% lead.

It’s all about delivering high frequencies on a few cores and leaving all the heavy lifting to the GPU. Of course, if you’re 100% focused on CAD and BIM, the Nvidia RTX 4000 Ada Generation is overkill. You can save a significant amount by downgrading to an Nvidia T1000 (8 GB), AMD Radeon Pro W7500 (8 GB) (see page WS30) or similar.

Graphics choice

The verdict

The Workstation Specialists WS ICZ7900 comes with a massive choice of GPUs, from the Nvidia T400 GPU for true entry-level CAD to the Nvidia RTX 6000 Ada Generation for the most demanding viz workflows. Our test machine took up some middle ground with an Nvidia RTX 4000 Ada Generation GPU (20 GB), which is a great option for CAD-focused visualisation (read our review on page WS36). With plenty of horsepower and plenty of memory for viz tools like KeyShot, Solidworks Visualize and V-Ray, this powerful GPU makes the CPU’s all-core capabilities less important.

If you currently have a workstation with a 13th Gen Intel Core processor, this is probably not the machine for you. The performance gains with 14th Gen Intel Core in single threaded workflows are marginal, and you may even take a drop in multi-threaded performance. But if your workstation is older, and your priority is accelerating your CAD and BIM workflows, then this quality desktop machine is worth a look. It’s well built, quiet in operation, and while it’s a bit on the large side considering the components inside, it should serve you well, now and into the future.

AMD’s new mid-range workstation GPUs represent a solid foundation for 3D CAD and entry-level viz. However, by not having the option of a low profile form factor and holding back on memory in the middle of the stack, AMD has missed some opportunities in this price competitive market, writes Greg Corke Radeon Pro W7500 (8 GB) - £358 + VAT Radeon Pro W7600 (8 GB) - £492 + VAT Radeon Pro W7700 (16 GB) - £833 + VAT amd.com/radeonpro

n Spring 2023, AMD introduced the AMD Radeon Pro W7800 and W7900, a duo of high-end workstation GPUs based on the company’s RDNA 3 architecture. With 32 GB and 48 GB of GDDR6 memory respectively, both GPUs were designed for demanding workflows in media and entertainment and design visualisation. Despite offering buckets of processing power, AMD could not keep pace with Nvidia’s best, the Nvidia RTX 6000 Ada Generation (48 GB). However, the Radeon Pro W7800 and W7900 were hot on price/performance. In some workflows, the Radeon Pro W7900 could deliver 75% of what the Nvidia RTX 6000 Ada Generation could, for less than half the price (£3,200 +VAT vs £6,670 + VAT). Of course, not everyone has needs or budgets for such high-end pro GPUs. Many architects, engineers and product designers rely purely on CAD or BIM software, which is far less demanding from a GPU perspective. Meanwhile,

Targeting the mid-range All three Radeon Pro GPUs are designed to address the volume mid-range workstation market, which AMD describes as the $350 to $950 dollar segment. The GPUs comprise multiple unified RDNA 3 compute units (28 on the W7500, 32 on the W7600 and 48 on the W7700). Each compute unit has 64 dual issue stream processors, two AI accelerators and one second gen ray tracing (RT) accelerator. According to AMD, RDNA 3 offers up to 50% more raytracing performance per compute unit than the previous generation. The Radeon Pro W7500 and W7600 are full height, single slot GPUs, so are designed to fit in a standard desktop tower workstation. There are not compatible with small form factors (SFFs) / ultra-compacts. Both GPUs come with 8 GB of GDDR6 memory and four DisplayPort 2.1 Connectors, the latest version of the digital display standard. The Radeon Pro W7500 offers 12.2 TLOPs of peak single precision performance and has a total board power of 70W, so can operate with PCIe slot power alone. It costs £358 + VAT. The Radeon Pro W7600 boosts peak single precision performance to 19.9 TLOPs and has a total board power of 130W, so needs a 6-pin connector from the Power Supply Unit (PSU). It costs £492 + VAT. Finally, the Radeon Pro W7700 is a full height, dual slot GPU with four DisplayPort 2.1 connectors. It comes with 16 GB of GDDR6 memory and boasts 32 TFLOPs of peak single precision

and BIM software is CPU limited, where the GPU is held back by the frequency of a single CPU core. If all you ever do is model buildings in Autodesk Revit or design machinery in Autodesk Inventor, there’s little point in buying a high-end pro GPU. CAD software developers are slowly managing to better harness the power of GPUs in general. As they adopt more modern graphics APIs and push more of the graphics processing onto the GPU, this reduces the reliance on the CPU and hence the bottleneck. A case in point is the product design focused CAD software, Solidworks, which updated its graphics engine a few years ago. Prior to the 2020 release, performance scaled very little as you moved up the range of your chosen GPU brand. Now, there’s a fair bit of difference. With the SPECapc for Solidworks 2022 benchmark, there is a substantial gap between the W7500’s and W7700’s benchmark scores in simple shaded with edges display mode and when RealView is enabled for more realistic lighting and materials. However, this doesn’t mean you should buy the faster GPU simply because it has bigger numbers. It’s important to have some context. We loaded up the largest Solidworks model we have, a massive 13,000 component MaunaKea Spectroscopic Explorer telescope assembly, and still got good performance with the Radeon Pro W7500. Even at 4K resolution, it delivered a smooth 29 Frames Per Second (FPS) with RealView on, above the minimum recommended 24 FPS. With the Radeon Pro W7600 this went up to 52 FPS.

In Lumion, rendering out our sample scenes at FHD resolution with the ray tracing effect enabled, also pushed memory over 8 GB, resulting in significantly longer render times. To experiment, we processed the same Lumion sample scenes, but dialled down the monitor’s resolution from 4K (3,840 x 2,160) to 720p (1,280 x 720). This reduced the reliance on shared GPU memory and cut the render times from 1,160 seconds to 855. While working at 720p is highly impractical, it just shows that even small changes can have a big impact on performance when GPU memory is in short supply. All of this testing was done with single applications straight after a Windows reboot. In reality, this is not how architects, engineers and designers work. Running multiple applications at the same time can have an accumulative effect on GPU memory. In most CAD-centric visualisation workflows, users rely on a companion visualisation tool. For architects, it’s often Revit and Twinmotion or Revit and Enscape. For product designers, it’s Solidworks and KeyShot or Solidworks and Solidworks Visualize. For users to be able to swap quickly between these tools, each application must reserve some GPU memory. To find out what impact a shortage of memory might have on multi-application workflows, we loaded up a model in Solidworks then rendered it in Solidworks Visualize at the same time. Even with the relatively small 300 component computer model, memory usage soon went over 8 GB. And while the Radeon Pro W7500 still managed to render the scene OK, albeit slower than it would have done with everything stored in GPU memory, it also had an impact on user experience. Rendering at 1K resolution used 5.7 GB of GPU memory in total and both applications remained 100% responsive. This wasn’t the case when rendering at 2K resolution. It used up 7.7 GB of GPU memory and 3.8 GB of shared GPU memory, and when swapping back to Solidworks and trying to quickly reposition the model in the viewport, there was a small initial lag. Rendering at 4K resolution used up 7.6 GB of GPU memory and 7.8 GB of shared GPU memory. This caused more lag in Solidworks and Solidworks Visualize became quite unresponsive. On one of our test runs the entire Windows 11 OS froze. Meanwhile with 16 GB of GDDR6 memory, the Radeon Pro W7700 loaded everything in, resulting in a WS32

it outperforms the older Nvidia RTX A4000 and is priced almost identically. It even outpaces the new Nvidia RTX 4000 Ada which costs 40% more. However, it loses out on ray tracing performance, uses more power and takes up two slots on the motherboard so may not be compatible with as many desktop workstations. AMD also faces competition from Intel with its Arc Pro GPUs that effectively launched in 2023. Arc Pro GPUs have hardware ray tracing built in and are price competitive, but are not that widely available. The single slot 130W Arc Pro A60 is the closest in terms of positioning, and comes with 12 GB of memory. There’s also the entry-level low-profile 50W Arc Pro A40 and 75W Arc Pro A50, both with 6 GB.

Over the next few years, we expect to see ray tracing techniques combined with traditional rasterisation to deliver a much more realistic CAD viewport. The idea is that users will be able to flip into ‘ray traced’ mode, in much the same way they currently do with shaded, shaded with edges and realistic. Moving up the stack, the Radeon Pro W7600 goes up against the Nvidia RTX A2000. Both GPUs feature hardware ray tracing, but the Nvidia RTX A2000 has two advantages. One, it has 12 GB of memory, which gives it more headroom in viz focused workflows. Two, it has greater WS34

software compatibility, including support for V-Ray and KeyShot, although with the rise of DirectX-based real time viz tools like Lumion, Twinmotion, D5 Render and Chaos Vantage, this is changing. The other advantage of both Nvidia GPUs is that they are low profile boards. This means they can fit in standard desktop tower workstations and Small Form Factor / ultra-compact workstations, such as the HP Z2 Mini and Lenovo ThinkStation P3 Ultra. With these compact machines representing an increasingly big slice of the mainstream workstation market, not just on the desktops of users but in racks for remote graphics deployments (see page WS38), this limits the market for AMD. Finally, there’s the Radeon Pro W7700. In workflows that rely on rasterisation,

As AMD rolls out its RDNA 3 pro graphics cards for the volume workstation market it feels like there are some missed some opportunities. With no low-profile option, users have to rely on the previous generation Radeon Pro W6400 (4 GB), which is very much entry-level. If AMD had made the Radeon Pro W7500 compatible with this increasingly popular form factor, it would have immediately expanded its potential reach. Perhaps with these cards AMD is focusing more on specialist system builders like Armari and BOXX, who tend to only use standard workstation tower chassis. Alternatively, it possibly feels there is less need for a low-profile pro GPU moving forward as it plans to beef up its APUs (CPUs with integrated GPUs). At the same time, only giving the Radeon Pro W7600 8 GB of memory limits its appeal for visualisation workflows. It certainly has enough raw graphics processing power for entry-level workflows in Lumion, Twinmotion and others, but if you run out of GPU memory things can slow right down. Yes, you can adjust your workflows, but who wants to make compromises? When a workstation runs out of system memory, you can add some more. With a GPU, it’s fixed, and because you will typically have that card for three to five years, it’s important to get things right. Even 12 GB would have given it some headroom. Finally, in certain viz workflows, the Radeon Pro W7700 looks to be excellent value for money particularly compared to the Nvidia RTX 4000 Ada Generation, which costs 40% more. However, it’s let down a little by its ray tracing performance, which is only going to become more important to designers and engineers in years to come. www.develop3d.com

Review: Nvidia RTX 4000 Ada Generation Nvidia’s new flagship single slot workstation GPU might not offer as big a gen-on-gen performance leap as some 4000-class graphics cards from the past, but it’s a very solid performer for CADcentric visualisation, writes Greg Corke Nvidia RTX 4000 Ada Generation (20 GB) £1,159 + VAT www.nvidia.com | www.pny.com/professional

ver the years, Nvidia’s 4000 class pro GPUs have formed a very important part of the company’s workstation GPU portfolio. With a total board power of around 150W the single slot graphics cards have found their way into an extremely broad range of workstations, from the entry-level to the high-end. They have provided architects, engineers, and designers with enough horsepower to augment CAD and BIM modelling with more demanding workflows such as real time visualisation, VR, and others. The latest incarnation, the Nvidia RTX 4000 Ada Generation, is based on the AD104 graphics processor, the exact same chip found in the dual slot, small form factor version, the Nvidia RTX 4000 SFF Ada Generation. Both GPUs feature 20 GB of GDDR6 memory, 4 GB more than the previous ‘Ampere’ generation Nvidia RTX A4000. However, the full sized Nvidia RTX 4000 Ada Generation has slightly more memory bandwidth than its SFF sibling (360 GB/s vs 280 GB/sec). It also draws more power, and hence offers more performance. The Nvidia RTX 4000 Ada has 130W to play with compared to the SFF version, which has 70W. This means the processor can be clocked higher, resulting in more Chaos Group V-Ray 5.0 benchmark

horsepower across the board. SinglePrecision Performance is rated at 26.7 TFLOPs versus 19.2, RT Core Performance for ray tracing is rated at 61.8 TFLOPs versus 44.3, and Tensor Performance for AI is rated at 327.6 TFLOPs versus 306.8. Despite there being a significant performance difference between them on paper, both GPUs cost the same (£1,159 + VAT). In terms of price/performance, this means users pay a premium to have the AD104 chip in a small form factor or super compact workstation like the HP Z2 Mini or Lenovo ThinkStation P3 Ultra. Interestingly, the SFF version comes with a half-height bracket and optional fullheight ATX bracket, so can be used in full sized towers as well. This doesn’t really make sense unless you are particularly focused on using less power. The Nvidia RTX 4000 Ada Generation cannot draw all of its electricity from the PCIe slot on a workstation motherboard, so gets its additional power from a 16-pin 12VHPWR connector. This modern connector is only supported directly on new generation Power Supply Units (PSUs). It’s not a problem if your workstation doesn’t have one. Nvidia includes a standard 8-pin to 16-pin adapter, so you can plug into your existing PSU.

The pro viz workhorse For testing, we compared the Nvidia RTX 4000 Ada Generation (20 GB) to the SFF version, as well as the previous Ampere generation, Nvidia RTX A4000 (16 GB). Here, it’s important to state that our benchmark comparisons aren’t perfect, as not all GPUs were tested in the same workstation. For the Nvidia RTX 4000 Ada Generation and Nvidia RTX A4000 we used the 537.7 driver inside an AMD Ryzen Threadripper Pro 7800X workstation from Armari. For the Nvidia RTX 4000 SFF Ada Generation, we used the 536.25 driver inside an AMD Ryzen 7950X3D-based workstation, also from Armari. PNY loaned the Nvidia RTX 4000 SFF GPU to us several months ago, so we no longer have the card.

As both CPUs are built around the same AMD ‘Zen 4’ architecture and hit similar single core frequencies, any variance from testing on two different systems should be very small. Our testing focused predominantly on design viz, with the architectural-focused Twinmotion, Lumion, V-Ray and Nvidia Omniverse, the product design focused KeyShot, and Unreal Engine with an automotive model. We also tested with CAD software Solidworks, although for a GPU with this much horsepower, it’s a given that you’ll get good performance. The big trend in visualisation at the moment is the expansion of GPU ray tracing for much more realistic renders. GPU ray tracing used to be handled exclusively by offline renderers like V-Ray and KeyShot. Now it’s also available in real time viz tools, typically enabled through the graphics APIs DirectX 12 with DirectX Ray Tracing (DXR) and Vulkan Ray tracing. In Unreal Engine, Twinmotion, Lumion, Omniverse and others, users can choose between standard rasterisation, or ray tracing to increase visual quality and realism. This is all done on the GPU and has largely been driven by Nvidia, and the dedicated RT and Tensor cores in its RTX cards. In the Nvidia RTX 4000 Ada, the RT cores are third generation, and the Tensor cores are fourth generation. While it has the same number of cores as the Ampere-based Nvidia RTX A4000, all are one generation ahead. As you would expect, ray tracing increases the load on the GPU. In Unreal Engine, when testing at 4K resolution with the Audi car configurator model, viewport performance went down from 29.64 Frames Per Second (FPS) with ray tracing disabled to 18.31 FPS with it enabled. This is below the ideal 24 FPS, but navigation within the scene was still relatively smooth. On paper, it’s not a massive improvement over the Nvidia RTX A4000 (14.11 FPS) but there was a noticeable difference in terms of how easy it was to quickly and accurately reposition the model in the For more performance data see page WS30

In general, the Nvidia RTX 4000 Ada Generation was about 25% to 30% faster than the Nvidia RTX A4000.

Remote possibilities: Lenovo targets the cloud With its ThinkStation workstations now fully-optimised for racks as well as desktops, Lenovo is focusing on complete solutions for remote workstations, with an agnostic approach to software, writes Greg Corke

n the early days of the cloud, a simple explanation was that it was someone else’s computer, accessed remotely. This might be true, but when it comes to cloud workstations, you’re typically sharing that computer with many other users through a technology called virtualisation. Virtualisation carves up CPU, memory and sometimes graphics resources from a single computer to create multiple Virtual Machines (VMs). The processors that are typically used in cloud workstations have lots of cores but run at relatively low frequencies. And as we showed in our May 2023 Workstation Special Report, this can mean considerably less performance, when compared to the fastest desktop workstations. With an operational expense (OpEx) model, instead of a capital expense (CapEx) model, cloud workstations can also cost more over several years. This has presented a big opportunity for the major workstation OEMs. HP, for example, has built an integrated remote workstation solution around its HP Z desktop workstations and HP Anyware, the remote workstation or digital workspace software. The idea is that users can remote into powerful desktop workstations, typically stored in racks in a server room or datacentre. As with cloud workstations, all processing, including graphics, is done remotely, with only pixels streamed to the end user, wherever they may be. HP’s acquisition of Teradici in 2021 put the spotlight on HP for remote workstations. Meanwhile, Lenovo has been quietly building up its remote workstation capabilities. The company WS38

really started to become vocal about its plans for the datacentre with the launch of the ‘Sapphire Rapids’ Intel Xeonbased ThinkStation P7, P9 and PX in Spring 2023, followed by the AMD Ryzen Threadripper Pro-based ThinkStation P8 in Autumn 2023 (read our review on page WS22). These powerful tower workstations sit pretty on any desk, but were also purpose-built for racks. The ThinkStation PX comes with a redundant power supply, front accessible storage, a rear power button, and an out of band baseboard management controller (BMC) for server level control. In the main, however, these machines still require virtualisation when part of a remote workstation solution. Only the most demanding users need all the resources of a single machine. And while their Intel Xeon and AMD Ryzen Threadripper Pro processors are specifically designed for workstations and are more modern and powerful than those typically used in cloud workstations, they still have lots of cores and lower all core frequencies than the fastest CAD-focused workstations. To deliver a true desktop experience, remotely, that feels familiar to users The ThinkStation P3 delivers impressive performance for CAD over a 1:1 connection and with a compact form factor, seven workstations can fit in a 5U rack space

of CAD and BIM software, you need a different type of machine. With a high frequency Intel Core processor and powerful Nvidia RTX GPU, the ThinkStation P3 Ultra delivers exceptional performance for CAD-centric workflows over a 1:1 connection. The chassis is extremely small, so you can get seven units in a 5U rack space for that all important server room density. But, importantly, there’s still room for a BMC add-in card for remote monitoring and systems management. Lenovo’s cloud / remote workstation play isn’t just about hardware, however. It’s about delivering comprehensive remote workstation solutions, as Mark Hirst, Lenovo’s workstation solutions manager for remote graphics + hybrid cloud, explains, “We can’t just talk about the CPU and the GPU in these [our workstations]. If we’re going to educate our customers and educate our partners and educate ourselves, we’ve got to do a much better job about talking about the entire technology stack around it. “Our customers don’t just want to talk workstations, they want to talk datacentre, they want to talk data management, they want to talk remote protocols, they want to talk networking, security, all this kind of stuff,” he says. In order to best support its customers on their remote workstation journey, Lenovo is developing a Remote Centre of Excellence at its workstation HQ in Raleigh, North Carolina, USA. The centre will act as a hub for research and as an educational and developmental resource for customers, who can test solutions remotely. “We want people to really understand that there’s an alternative to cloud and we want our customers and our partners to try these systems out. If they want to learn about different protocols, then we’ve got the expertise in house to be able to educate them on that and on other things in the stack as well.” In the Remote Centre of Excellence, Lenovo is racking all of its different desktop workstations and configuring them with various different remote graphics software protocols. In the past, Lenovo had a big focus on Mechdyne TGX, but now it’s also testing its kit with Nice DCV from AWS, Splashtop, Parsec, Microsoft Remote Desktop, and even HP Anyware (formerly Teradici CAS), www.develop3d.com

Inevidesk: flexible virtual workstations Inevidesk’s flexible and transparent approach to virtual workstations should resonate with UK firms that want to enable their staff, wherever they are based, to work off the same infrastructure, writes Greg Corke

ne of big unknowns of Virtual Desktop Infrastructure (VDI) or cloud workstation solutions is how much they cost. With no one size fits all approach, few service providers publish clear pricing. There can also be hidden charges along the way. Compared to buying desktop workstations outright, and typically keeping them for three to five years, cloud workstations can also end up being very expensive. London-based Inevidesk has built its CAD-focused virtual desktop business around transparency, putting pricing up front and centre on its website (see table right). Typically, customers buy the hardware up front, just as they would with desktop workstations, then pay an annual service fee on top. This includes the virtualisation platform, access to the administration portal, as well as support and service updates. Inevidesk builds its solution around pods, bespoke rack mounted servers that can host up to seven GPU-accelerated virtual desktops, known as vdesks. Each vdesk gets a dedicated GPU. Customers can choose to keep their pods on premise, in their own server room. Alternatively, as the majority choose to do, pay a fee to have them hosted in Inevidesk’s London datacentre, which is powered by 100% renewable energy. Buying hardware outright is fine if you know exactly where your business will be in a few years, but few firms these days do. To make things more flexible, Inevidesk recently introduced its Flexidesk service. This allows firms to burst up and scale down in increments of one or more vdesks, without having to buy the hardware. Well, that’s not 100% correct. In order to use the Flexidesk service, customers must own at least one pod and it must be hosted with Inevidesk. With the Flexidesk service, the commitment can be for as little as one month, although it works out cheaper to sign up for a year. Prices start at £99 per month and include the vdesk, service and hosting fees. Buying pods is more cost efficient, so firms can strike a balance between renting www.develop3d.com
