Reviews of AMD’s Zen 5 processors this week surprised many, with lower-than-expected results. After some investigation, we discovered that turning off Simultaneous Multithreading (SMT) can yield notable performance gains, particularly in gaming. This article presents our findings, including comparisons with the 7800X3D and 7700X with SMT turned off.

    Or they just found out that Windows process scheduler is still broken beyond repair. If you look at the benchmarks on GNU/Linux performance is all there. For example see Phoronix benchmark

    This is shockingly stupid. SMT has been a thing on x86 long enough for it to be able to buy it’s own alcohol and yet somehow the windows scheduler STILL can’t fucking deal with it?

    I’m not a kernel-level developer or anything but I mean, at some point you have to wonder how fucking trash windows kernel internals are that this problem keeps happening over and over and over and…

    During the course of our testing, we observed that Windows 11 was scheduling workloads on the 9700X in a manner that would try to saturate a single core first, by placing workloads on each of its logical threads.
