Yep, they are, seems that Intel Xe will succeed Phi:


But probably only for special purpose and enthusiasts, so not 
very relevant for UI. One interesting point regarding UI is that 
Linux drivers for AMD APUs support zero-copying using the unified 
GPU/CPU memory:


Whereas Intel on-die GPUs seem to require copying, but it isn't
