Skylake?

Author:

The Skylake Xeons that have been announced use the "client" Skylake core (and uncore) and do not support AVX-512.
This is similar to the previous mixing of "client" and "server" uncores across Core i7 and Xeon E3 platforms, but of course this is the first time that it impacts the ISA.

The last 3 major core releases have had ~18 months between the release of the first "client" part and the release of the 2-socket server part, so if that schedule is repeated we should see the Skylake Xeon EP in 1H2017. Earlier seems unlikely, since we have not seen the "Broadwell EP" yet. Later is certainly possible, since this is the first time that there has been a major ISA-level difference between the "client" and "server" core.
