GPU HW dude, here: I’m not sure of AVX-512’s current fma16 story, but it’s predecessor (LRBni) was terrifyingly good at fma32–much better than contemporary GPUs. The problem with those parts is total power displacement (TDP). The market is really geared to mobile; so, so that became less of an issue. INTC-for-Graphics is hampered by the lack of deep, dedicated latency hiding fixed-function HW. Otherwise, INTC is probably a strict win over any discrete GPU.
