That's actually older Intel CPUs. I believe only Rocket/Tiger Lake supports it.

Will you upload benchmarks for this Michael?

Yeah https://en.wikipedia.org/wiki/AVX-512#CPUs_with_AVX-512 AVX-512 is a complete mess. It doesn't seem worth the die space to include it in a CPU design or the performance hit to use it if your CPU has it.

So when will VLC support it or update to it?

probably a long time, as vlc was updated only recently after many months which included v0.91 if i recall.

That's a shame!
I tried recently to play a 4K HDR AV1 file on my laptop and on my desktop and I couldn't, the video was too laggy.
Maybe after VLC manages to update it up to this version, I will be finally able to play it normally, at least on the desktop.

should try and use MPV, it's quite good.

the new version of vlc was released 12 days ago, not sure if you used that version or not. P.S 4k AV1 would certainly use a huge amount of cpu, i'm sure you could play 1080p if your laptop/desktop is recent.

It doesn't worth the die space on a desktop CPU. I'm sure plenty of workstations could put AVX-512 to god use, though.
