>Huge vector units like AVX-512 are mainly useful for workloads that need huge amounts of RAM that you just can't get with a GPU, or for workloads that are very latency sensitive and incompatible with GPU task scheduling because they are in some other CPU-bound code.

There are a lot of tasks that a GPU can do faster than a CPU but it would require batching a large amount of work before you can gain a speedup. EYPC CPUs do not suffer that limitation. If all you have is an array with 4 elements you can straight up run the vector instructions and then immediately switch back to scalar code. Meanwhile with a GPU you probably need at least an array with 10000 elements or more.
