I am going to pretend you didn't say Geekbench, but do you have a source for the Blender and V-Ray comparison? I honestly have not seen that yet.
Even if you dont like it Geekbench5 is actually a pretty good test and needs to be taken into account, here the Threadripper is very competitive
Also, PugetSystem did not include the Threadripper Pro 3995WX on their Xeon W9 benchmarks, luckely we have numbers from previous Reviews made by them, those Threadripper are air cooled, stock Threadripper on a waterloop will be even more impressive.
To the MT numbers.
In Blender the 3995WX gets 1093 points, the W9 3495X gets 1078, so the 3995WX has 1.4% advantage
In V-Ray the 3995WX gets 48,300 points and the 3495X gets 50,800 so thats a 5% advantage that goes to the 3495X.
For the "Mid-Range" HEDT Pay attention to the 32 core 3975WX, its also a match for the 28 core 3465X
AMD's new Threadripper PRO 5000 WX series of CPUs are here, providing greater performance over the previous generation while maintaining the large memory capacity and high PCIe lane count that Threadripper Pro is known for. But just how much faster are these new processors in content creation...

I wish PugetSystem would have included the 3000 series Threadripper Pro on their tests, many are on that Generation of HEDT CPUs and Would like to know if its okay to upgrade now or wait for Zen4 based Threadripper.
