The things I want AVX512 for in a laptop:

- AV1 encoders

- VapourSynth

- llama.cpp

- whisper.cpp

- numpy

...That's about it. Autovectorized AVX512 system packages from CachyOS, Clear Linux and such would be cool, but I can live without that.

AV1/VapourSynth are branchy, and actually a reasonable fit for CPUs. Everything else seems like it would work well on IGPs, but alas it has not been done yet. shrug

AVX is very useful for audio DSP when you care about latency. Which is mostly in the pro audio niche.

Linux has this “pulseeffects” package with some nice features (eq, left-right balance), but it is a real CPU hog (especially for something that sits in the background all the time). Kinda wonder if it is worth re-compiling for avx-512…

Yeah, but one or two cores should handle it just fine. If it really is a hog, it probably needs some optimization. Real-time audio DSP has been a thing for decades and should not be a hog.

It is running on my laptop so I’m probably being unusually picky.

Looking at the source, it looks like pulseeffects doesn't run any of the DSP itself. It uses a number of lv2 format plugins to process the audio.

Would love to get my Acustica Audio plugins to use less CPU. I've heard good things about the 7XXX processors for this.
