I'm surprised. Intel is killing it off with Alder (lava) Lake.

It's still there on server parts, and with growing functionality.

Intel overestimated the speed of changes in the software realm. Alder Lake have some cores which support AVX512 and some that don't support it yet.

I guess the optimistic thinking was that software would adopt, somehow.

But software was barely able to adopt cores with different speed, neither Linux nor Windows is ready to deal with cores with different instructions sets!

Thus it was easier for Intel to disable it rather then try to create some buggy driver which would do something with that mess.
