Why the AMD Ryzen Threadriper 2990WX is slower than it should be (video)

Level1Techs took a deep dive into the performance problems of AMD's Ryzen Threadripper 2990WX to figure out why this HEDT processor suffers from performance regressions on Windows. Contrary to some previous analysis, it appears the issues aren't caused by a memory bandwidth, because the problem doesn't show up when testing Linux-based versions of the same software. Instead, the problem is a bug in the Windows kernel. Level1Techs even cooperated with Jeremy from BitSum to create a fix called CorePrio.
With this work-around in place we can nearly double the performance of Indigio on the 2990WX as reported by Anandtech, The Tech Report, and ourselves.
You can read the full piece over here. It's surprising that this issue gets uncovered and fixed by tech enthusiasts, rather than by AMD and/or Microsoft.
