I think this post focused on the wrong things here. CPUs with AVX-512 also have massive data parallelism, and CPUs can execute many instructions at the same time. The big difference is that CPUs spend a lot of their silicon and power handling control flow to execute one thread efficiently, while GPUs spend that silicon on more compute units and hide control flow and memory latency by executing a lot of threads.
