Threadripper 2990WX Performance Regressions? Not so fast...

From the creator

Let's talk about the curious case of the 2990WX performance regressions vs the 2950X where the 2990WX performs worse *on windows* than Linux. I think the issue goes deeper than scheduling -- something else is broken with this many threads. I've also seen the recent driver bugs in the nvidia driver for performance regressions there -- it's not as useful to look at that because it's cross platform -- but I suspect that (at least on windows, before "windows 10 for workstations" is a thing) 32 cores is more machine than windows can handle. I was a bit surprised to confirm the performance delta is as much as it is. ALSO NOTE: I'm not really wanting to be team red/team blue but with this tweak the 2990WX DESTROYS the 7980XE in Indigo now :D For those of you that keep score. Left out here for time was 7zip. FWIW 7zip behaved wildly inconsistently even doing the powershell thing. In some bench runs I could get similar performance to Linux in but other times the performance regressed https://blogs.technet.microsoft.com/markrussinovich/2008/09/22/the-case-of-the-slooooow-system/ https://forum.level1techs.com/t/what-is-numa-level-one-techs/132060/6 https://techreport.com/review/33977/amd-ryzen-threadripper-2990wx-cpu-reviewed/6 ********************************** Thanks for watching our videos!
