Frankly, I don't find that especially convincing. Despite console CPUs being slow compared to PC, There are plenty of games that require more than lowest performance CPU. If targeting AVX2 would allow large performance improvements, it would make sense to support it and run better on lower-clocked mobile CPUs or on dual-cores instead of just on quad-cores and better.

And I presume you are talking about AVX2. Both PS4 and Xbox One support AVX, and that alone obviously didn't gather any significant support (even though consoles have much more benefit from CPU optimizations compared to PC).
