Meanwhile these CPUs are amazing on Linux

For some reason Windows scheduler is not as good as the one found in the Linux kernel with the zen5.
The BORE scheduler on Linux is even better, as it's specifically optimized for the features in these chips.
Not yet in the Torvalds tree of Linux? There's a ton of interesting schedulers coming when sched_ext lands to the mainline:

Also, would be great if more distros would compile packages with AVX512, there's a ton of perf left on the table:

I don't think they're gonna switch schedulers that quickly. They only changed from CFS (which they used for decades) to EEVDF last October.
Not until sched_ext lands, and you can then switch schedulers as you wish. Maybe in 6.12?
Oh that's cool. Looks very promising.
