What isn't clear from this announcement is whether the future Xeon processor with AVX-512 support will actually be a socketed MIC, or a CPU (more precisely Skylake)? Is it coming to consumer CPUs in a similar timeframe? Developers might want to know, to determine whether to adopt AVX2+ or heterogeneous computing. The latter would benefit the competition more than it would benefit Intel.
