AMD Ryzen Threadripper 2990WX performance can see up-to 2X Boost with CorePrio tool
There's no denying that AMD has outted a very credible 32-core processor with the Threadripper 2990WX, however in certain conditions and even gaming, performance regresses as most software has no idea what to do with so many threads let alone Windows dealing with assigning the fastest cores towards the right software.
That seems to have been addressed with a 3rd party utility. LevelOneTechs posted a blog identifying key issues with the complicated design and actually have been able to fabricate a solution for the Threadripper performance regressions. LevelOneTechs mentions that programs such as Adobe Premiere, Indigo's Renderer, 7zip as well as games using Nvidia drivers have been seeing patches with varying degrees of success, he tested extensively to see what was going on. While testing the Indigo renderer Wendell noticed that "taking a single thread out of the list of available threads to run the program on (called CPU Affinity) via the windows task manager would improve performance to similar levels as he was seeing on Linux".
They decided to isolate this behavior and then got together with Jeremy Collake at Bitsum to create a utility called CorePrio. In the utility there is a checkbox for 'NUMA Dissociater' which effectively eliminates the Windows vs Linux performance disadvantage by automating the thread tweaking. Once you watch and read the entire documentation, you wonder this: AMD needs to work with Microsoft to get a kernel level fix so that the CPU works as intended. It's a long and deep story though, that is told best by watching the video really, have a read and grab Coreprio here.

IMO this is AMD racing to bring something sensational to market before it actually was ready. This isn't MS's fault, and this "fix" is lacking...
The Xeon 8180 is released, and it actually works. Intel worked with Microsoft BEFORE the release to ensure that it actually functions as intended...
Phoronix showed yesterday that Coreprio reduced performance in various loads. It can hurt as much as it helps depending on the load. Server 2019 performed very differently than Windows 10 in some of Michael's tests. Indigo does even worse on Server 2019 than on Windows 10, while in other benchmarks Server 2019 beats Windows 10, with or without CorePrio.

IMO this will get "fixed" in windows when Intel releases their 28 core CPU.
