But are those key workloads for the vast majority of their customers?
Probably not a majority of server, and certainly not for client. You could argue about what the balance of server vs client is for Intel, but regardless maybe we'd all be better served if they had a clear "FP heavy workloads" core vs. "everything else" core. Obviously, Intel did have this split with Xeon Phi, and decided to go the opposite direction by folding AVX512 into mainstream server, aka all of this convergence-optimized core the marketing keeps parroting.
From the outside, it seems more like a late reaction to the preeminence of GPUs in HPC and ML, and Intel not wanting to acknowledge it until very recently.

Maybe that's more an issue with GPU memory capacity, and the GPU programming model in general. Supercomputers seem to have decided this programming model is an issue, since all 3 of the announced exascale machines are going for some sort of shared/coherent memory model between CPU and GPU.
