Instruction Sets: Alder Lake Dumps AVX-512 in a BIG Way

https://www.anandtech.com/show/16881/a-deep-dive-into-intels-alder-lake-microarchitectures/5

This is pretty ironic. AVX 512 was one of the "selling" points of Rocket Lake but a weak one at that but the funny thing is, Zen 4 will have AVX 512. So you are in a situation where Intel no longer cares about AVX 512 in their consumer chips but AMD does. For HEDT line and Server, those may still support it however but not sure yet.

100% intel going to support AVX 512 on Sapphire Rapid.  There no other reason why Golden Core would have AVX-512 on it.  Why make a core with AVX-512 if you not going to support it on anything.  

The question is will AMD support AVX512 on Ryzen or will they disable it on ZEN 4 just like intel disabling it on Golden Cove for Alder Lake.

I'd be surprised if AMD disables it in Zen 4 as that would be a pretty easy selling point even if many consumers may not get much use out of it.
