When is AVX 512 on a chip, not just an emulator?

[Thomas_H_]

I'm having a really hard time finding anything other than rumors about this. I have seen the official statement that Broadwell chips will be available before Christmas, but I can't tell if Broadwell includes the AVX 512 extensions or not (I've heard both ways).  Anyone know for sure? Better yet can anyone point me to a link on intel.com that provides a definitive answer?

Broadwell is basically a die shrink of the current Haswell, so it will have add a few instructions and will not have AVX512. "At its heart, Broadwell will be a shrunk-down cousin to Haswell."

I expect to wait for AVX512 until Skylake in 2015-16, since Xeon Phi is too costly and not the form factor I need.

I know and I can supply URLs too.

Answer: Knight Landing will be first.  (as Mark pointed to: https://software.intel.com/en-us/blogs/2013/avx-512-instructions)

Knights Landing is scheduled to ship in systems in the second half of 2015. (http://newsroom.intel.com/community/intel_newsroom/blog/2014/06/23/intel-re-architects-the-fundamental-building-block-for-high-performance-computing)

Based on this very recent document:

https://gcc.gnu.org/wiki/cauldron2014?action=AttachFile&do=get&target=Cauldron14_AVX-512_Vector_ISA_Kirill_Yukhin_20140711.pdf

AVX-512 will be available in Knights Landing Xeon Phi and Skylake Xeon

We can suppose that the same core is used for Skylake desktop/laptop/mobile and server (as all cores back to Pentium II or even before), so AVX-512 may well come in the first batch of SKL client products, potentially before the release of KNL Xeon Phi (unlike previously stated)
