AMD admits its chips actually have gaming 'parity' with Intel's 14th Gen, suggests lacklustre Ryzen 9000 performance could be because we're not fiddling with Windows' backend
AMD admits its chips actually have gaming 'parity' with Intel's 14th Gen, suggests lacklustre Ryzen 9000 performance could be because we're not fiddling with Windows' backend
AMD says it's "heard from the community" and has updated its official performance figures for the Ryzen 9000-series.

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.
I wouldn’t be even mildly shocked to eventually find out that there’s some sort of back room deal between MS and Intel
Me neither. But. I think the answer is much simpler here: Microsoft doesn't make their money with schedulers, but bundling that Office and tracking to everybody, and charging rent every month. They have way less people working on making the kernel as fast as possible, compared to Linux where:
- there are many companies running crazy workloads 24/7, and providing patches
- very talented individual hackers who have an open source kernel and can play around with things, getting that last oomph out from their system
This is why, for a pro user, Linux is an amazing platform.
Wait a minute. Was this sarcastic or do I get to lore dump? In case you weren't aware, Intel has been doing this shit to AMD for decades. And so has Nvidia.

Like this was a 3 minute Google search adventure.
I'm assuming they're specifically meaning a deal regarding not fixing the scheduler issues
To be completely honest, I'd be more surprised if there wasn't.
The next steam deck is gonna be amazing. I mean the current one is, too
Yeah, same with the next gen zen5 laptops. The Ryzen 9950x can compile code faster and by using less power compared to 7950x. It is going to be awesome for dev laptop performance and battery use.
The BORE scheduler on Linux is even better, as it's specifically optimized for the features in these chips.
It's pretty easy to patch the kernel in NixOS:

It definitely feels snappier even with my 5950x. I hope this lands to mainline soon, compiling kernel for every update takes a few minutes extra.
There are custom pre-compiled kernels that come with BORE. Not sure about Nix and I don't know if they even have custom kernels in the repos at all, but there is linux-cachyos-bore on Arch. CachyOS is a pretty cool Arch-based distro that offers multiple kernels with different optimizations. They also put them in the AUR, so any Arch user can install them.
They have a few in the main branch: https://github.com/NixOS/nixpkgs/tree/master/pkgs/os-specific/linux/kernel
I see rt and zen at least being available. Would of course be quite easy to just send them a PR for bore patches, but I think I wait for sched_ext to land instead...
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:
Not yet in the Torvalds tree of Linux?
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.
