The value of AVX512 is more in the extra instructions it provides than in its (somewhat illusory) wider data path.
No doubt the 5nm or 3nm chips will actually deliver the 512-bit path. It must be a crushing burden to come up with actually helpful uses for another billion transistors. And it must be frustrating knowing those AVX512 data paths usually sit idle because compilers don't know how to use them.
