All three models support 128 PCIe 4.0 lanes, 2TB of DDR4-3200 octa-channel memory and a TDP of 280 watts. This means AMD has officially killed off the HEDT version of Threadripper and replaced it with the workstation version called Threadripper Pro. So what's changed and why have they done this? The Threadripper Pro 5995WX was 10% faster than the Xeon w9-3495X when registering our 99 GB dataset. Both CPUs lagged behind AMD’s and Intel’s consumer processors. Even though those test machines only had 64 GB of memory, so only ran on 5 threads, their higher frequencies and IPC gave them the lead. Another model expected for AMD'sRyzen Threadripper Pro is the ASUS WRX80 Pro Sage SE WIFI. While we don't have anytechnical information and specifications from ASUS itself, we do have an image of it that VideoCardz reported on. There's a lot to go on from just the image, and it looks as though ASUS willfully utilizeall of the PCIe 4.0 lanes from Threadripper Pro.

The 280W Threadripper Pro 3975WX weighs in at 32 cores and 64 threads that run at a 3.5 GHz base and 4.2 GHz boost, which is significantly lower than the Threadripper 3970X's 3.7/4.5 GHz base/boost. The chip has a significantly higher boost frequency than its 32-core EPYC 7542 comparable (+800MHZ) but a lower base frequency. The GIGABYTE WRX80 SU8 includes seven full-length PCIe 4.0 x16 slots, with a large chipset heatsink on the right-hand side. While it's difficult to determine a lot of the storage specifications from the image we have from VideoCardz, we can see it may include three to four Ethernet ports on the rear panel. Overall CAD isn’t a key target workflow for Intel ‘Sapphire Rapids’ or AMD Ryzen Threadripper Pro. In fact architects, engineers and designers that only use bread-and-butter design tools like Solidworks, Inventor and Revit, will almost certainly be better served by 12th or 13th Gen Intel Core processors or AMD Ryzen 7000 ( read our comparison article). Based on AMD Labs testing as of January 31, 2022, using the Chaos V-Ray v5 (Update 1.1) benchmark tool to measure CPU rendering performance of an AMD Ryzen Threadripper Pro 5995WX reference system configured with 8x32GB DDR4, NVIDIA Quadro RTX A5000, 1TB SSD, Win 11 vs. a similarly configured BOXX APEXX4 workstation with an Intel® Xeon® W-3375. Results may vary. CGP-05. Another big difference is memory support. Whereas AM4 processors support dual-channel memory, HEDT chips like the 3970X and 3990X utilize quad-channel memory. However, the Threadripper Pro series goes a step further by supporting octa-channel memory. That's eight DDR4 memory channels just like it's offered on Epyc server processors.Ever since their introduction, the Ryzen Threadripper CPUs have offered impressive rendering performance,” said Vlado Koylazov, Academy Award Winner and Co-Founder, Chaos. “The new Threadripper PRO 5000 WX-Series processors further improve on this, allowing 3D artists and architectural visualization professionals unparalleled ability to accomplish even more in less time.”

We put both of these chips through a test suite of professional-class applications, like SPECworkstation and SPECviewperf, along with our standard application test suite. And yes, we put the chips through our gaming test suite to see how they fare. For comparison we've included the Threadripper 3990X which was tested on the MSI Creator TRX40 motherboard using the same Team T-ForceDDR4-3600 memory at 3400. Then we have a few desktop CPUs for comparison: a Ryzen 9 5950X tested with dual-rank DDR4-3200 memory, and the Intel Core i9-12900K using DDR5-6400 memory. The graphics card used for all testing is the GeForce RTX 3090 Ti. Let's get into the data... BenchmarksThe Xeon w9-3495X did show a small but significant lead over the Threadripper Pro 5995WX in the rebuild, convert and simulate tests. But the Xeon w9-3495X didn’t have things all its own way, lagging behind in the mass properties and boolean operations tests. AMD also bumped maximum memory capacity up to 2TB in systems that support two DIMMs per channel, a big jump over the 256GB supported with the company's own consumer models, not to mention Intel's competing Xeon W chips that have a 1TB limit. You'll have to step up to Intel's Xeon Scalable lineup, which is largely meant for servers instead of workstations, to match Threadripper Pro's 2TB of memory capacity. Unveils Ryzen Threadripper 7000 Series processors, the world’s fastest desktop processor, for the world’s fastest desktop platforms for enthusiasts – Threadripper Pro has 128 PCIe 4.0 lanes (the CPU exposes 120 lanes to the user) compared to Intel's 64 lanes, an advantage because most workstations have plenty of additives, like GPU accelerators, NVMe storage, and high-speed NICs.
