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.

Because if you going to let people run AVX-512 you also going to have to support the power consumption and heat it requires.  Good article by AnandTech on just how much more power is require when running AVX-512 work loads
