AMD Ryzen Threadripper PRO 9995WX vs AMD Ryzen Threadripper PRO 9975WX

Both are sTR5 workstation chips with 8-channel DDR5 ECC and 128 PCIe 5.0 lanes, so the platform is the same. The 9995WX triples the core count to 96 and carries a much larger 384 MB L3 cache, which is what you want for rendering, simulation and heavy multithreaded work. The 9975WX runs 32 cores with a higher 4.0 GHz base clock, so it is easier to cool and feeds a workstation that leans on single-thread speed. Owners of big Threadripper PRO chips consistently report that the top-core part pays off only when the software scales across all cores.

• Choose the Threadripper PRO 9995WX if your work is heavily multithreaded, such as 3D rendering, CFD or large compile jobs, and the software will use 96 cores.
• Choose the Threadripper PRO 9975WX if you want a quieter, cooler workstation with strong single-thread speed and do not need the full 96 cores.
