What will be the simd width? Will it support avx512?
- wmf 10y agoIt appears to be the same old 256-bit Skylake core.
- roel_v 10y agoThank you.
- bitL 10y agoSkylake Xeons are supposed to support AVX-512 and Kaby Lake was supposed to be the first desktop platform enabling them, so there is hope ;-)
- velox_io 10y agoHopefully AMD's Zen desktops support AVX512, forcing Intel's hand.

- roel_v 10y agoI bought a Haswell Xeon (e5 1630) just this week for a new workstation build, because it was the only Xeon with high ghz that was available at a reasonable price (ie comparable to i7). E.g. the e3 1280 is a skylake xeon but 'only' supports avx2. Maybe the e7 skylake ones have avx512? I didn't look into those as they were out of my budget anyway :)
