AMD Zen 4 AVX-512 Performance Analysis On The Ryzen 9 7950X

We shouldn't be wasting *untold thousands* of man hours reworking code just for the benefit of a trillion dollar company that *went out of its way* to screw everyone over. We should be beating it into Intel's sociopathic skull via the only means they care about - money - that we're tired of picking up their dogshit. The only way to do that, and to keep this from happening again and again, is to support Zen4 and any other complete AVX512 implementation, and let Intel's broken garbage ones go f**k themselves.

If that means some Intel customers get the short end of the stick and go with AMD next time instead because of it, that's how things *should* be,

Intel would likely thank you for selling lots of their new Sapphire Rapids Xeons, because those support a superset of what Zen4 does.

Not the point though, and you know it.

Zen4's subset is what will - or at least, should - define AVX for the next 5+ years. Anyone who wants to keep chasing whatever the latest random instruction Intel added to win a benchmark with is welcome to do so, and in some workloads it might even be worth the effort; but the rest of the world should have the sense to realize that now is the time to get off this particular hamster wheel.

To the extent newer instructions are deep learning-focused, you only really need a few libraries to support them. In that sense, they're kinda like crypto extensions.
