Indeed it does. And, yes, it does not support AVX 512 or AVX3. Some intel motherboards have the ability to adjust these things in order to pass new version of Prime to lower thermals.Ryzen supports AVX2: https://en.wikipedia.org/wiki/Advanced_Vector_Extensions#CPUs_with_AVX2, AVX512 is something different.
Realbench tests for these things, too, but only the makers of Prime know why their tests are tougher. I bet regular apps that use AVX won't exact same load. I am not saying the programmers of Prime screwed something up but as a result of the addition of AVX tests, adjustments may be necessary to be made in the BIOS.
