Workstation CPU and GPU Benchmarks Test Notes
Some of these applications also make an appearance in our standard test suite, but those test configurations and benchmarks are focused on a typical desktop-class environment. In contrast, the following tests are configured to stress the systems with workstation-class workloads, which is a particular strength for the Threadripper processors given their hefty core counts.
With the exception of the W-3175X and Threadripper Pro systems, we loaded down our test platforms with 64GB of DDR4 memory spread across four modules to accommodate the expanded memory capacity required for several of these workstation-focused tasks. Due to the W-3175X's six-channel memory controller and our limited stock of high-capacity DIMMs, we used six 8GB DIMMs for a total capacity of 48GB. As mentioned, we're stuck with testing with 128GB of DDR4-3200 ECC memory for the Threadripper Pro system - and at JEDEC timings.
SPECviewperf 2020 on AMD Threadripper Pro 3995WX
The SPECviewperf 2020 benchmarks are hot off the press from the SPEC committee, so we decided to give the suite a spin with the Nvidia GeForce RTX 3090 to see how well the Threadripper Pro processors can push along a GPU in professional rendering applications. This has long been a weakness of previous-gen Threadripper processors, but the 3995WX performs admirably.
- The following short descriptions are from Bob Cramblitt, communications director for SPEC. Each entry has a link to more detailed test descriptions on the SPEC website.

- snx-04 - Siemens NX 8.0 - 10 tests ranging from 7.15 to 8.45 million vertices with wireframe, anti-aliasing, shaded, shaded with edges, and studio mode rendering modes.
Per-core performance continues to reign supreme in most graphics-accelerated workloads. As a result, we see the consumer-focused chips, with their higher clock speeds and/or more efficient architectures with higher IPC, take the lead in many of these benchmarks.
It is important to note that AMD now leads in workloads where it has traditionally trailed by large margins. The 3995WX took the lead over Intel's W-3175X and 10980XE in the Creo, CATIA, Maya (all of which benefit from increased octo-channel memory throughput), and Medical benchmarks.
The 10980XE led the Siemens NX benchmark, while the W-3175X offered comparable performance to the 3995WX. 3DS Max also served as a bright spot for the Intel processors, albeit by a slim margin. The seismic modeling Energy benchmark shows that performance is comparable between the various processors in some of these applications.
Overall, the Threadripper 3995WX delivered a solid showing in these workloads, notching a big step forward from previous-gen models in several workloads while diminishing traditionally-large deltas (nearly to the negligible range) in the benchmarks where the previous-gen Threadripper processors trailed by large margins.

Adobe After Effects CC Render Node Benchmark on AMD Threadripper Pro 3995WX
The After Effects render node benchmark leverages the in-built aerender application that splits the render engine across multiple threads to maximize CPU and GPU performance. This test is memory-intensive, so RAM capacity and throughput are important and can be a limiting factor.
No surprises here - the combination of the 3995WX's 128 threads, octo-channel memory, and PCIe 4.0 throughput yield 7% more performance than the consumer-focused 3990X and 9% more performance than the Core i9-10980XE - but be aware that the 3995WX has a memory capacity advantage here and it's hard to ascertain how much of the benefit stems from increased bandwidth or capacity.
Notably, the 3995WX leads the W-3175X by 21%, despite the latter's access to six-channel memory. We can likely chalk this up to the vagaries of Intel's mesh architecture.
Adobe Premiere Pro CC Benchmark on AMD Threadripper Pro 3995WX
This benchmark measures live playback and export performance with several codecs at 4K and 8K resolutions. It also incorporates 'Heavy GPU' and 'Heavy CPU' effects that stress the system beyond a typical workload. Storage throughput also heavily impacts the score.
The Threadripper processors are remarkably well suited for this type of work as they take sizeable leads over the competing Intel chips, and the addition of more memory and throughput benefits the 3995WX, which takes a 4% lead over the 3970X.
Adobe Photoshop CC Benchmark on Threadripper Pro 3995WX
The Photoshop benchmark measures performance in a diverse range of tasks, measuring the amount of time taken to complete general tasks and apply filters. This test leans heavily on GPU acceleration, and it's clear that high clock rates benefit performance tremendously.
While the consumer chips take massive leads in the test due to their superior per-core performance, the 3995WX is right in the thick of the competition with comparable workstation-class chips. The 3995WX leads the W-3175X by 10% while trailing the Core i9-10980XE by 3%.
SPECworkstation 3 Benchmarks on AMD Threadripper Pro 3995WX
The SPECworkstation 3 benchmark suite is designed to measure workstation performance in professional applications. The full suite consists of more than 30 applications split among seven categories, but we've winnowed down the list to tests that largely focus specifically on CPU performance. We haven't submitted these benchmarks to the SPEC organization, so be aware these are not official benchmarks. We've upgraded to the new 3.0.4 revision that supports spanning the tests that support the feature across processor groups and sockets.
Even though the SPECworkstation 3 software supports spanning workloads across multiple processor groups, not all applications can take advantage of the full 128 threads. As such, we're only presenting a few of the tests that indicate the benefit of increased memory throughput over the 3990X, or that show large deltas relative to competing chips.
SPECworkstation 3's Rodinia LifeSciences benchmark steps through four tests that include medical imaging, particle movements in a 3D space, a thermal simulation, and image-enhancing programs. Like many of the subtests, the thermal simulation tool only runs on 64 threads, but we see improved performance via the increased memory throughput and capacity.
NAMD is a parallel molecular dynamics code designed to scale well with additional compute resources and is one of the premier benchmarks used to quantify performance with simulation code. We recorded faster performance with the 3995WX in the smtv workload than with the 3990X, but most of the other subtests weren't impacted.
The earth’s subsurface structure can be determined via seismic processing. One of the four basic steps in this process is the Kirchhoff Migration, which generates an image based on the available data using mathematical operations. Like many of the tests in this suite, it doesn't span across processor groups, so these results represent performance with 64 threads active. Spinning up multiple VMs would result in higher performance in concurrent workloads.
The Calculix workload is based on the finite element method for three-dimensional structural computations, and it typically responds well to higher core counts. We see gains borne of the higher memory throughput, but they aren't explosive.
While we didn't see much of a performance improvement from increased memory bandwidth in most of the SPECworkstation 3 suite, these results are important - the performance gains borne of Threadripper 3995WX's copious helping of threads easily outweighs Intel's competing chips by large margins.
