"The instruction groups common to both the Intel Xeon Phi processor x200 and the Intel Xeon processor are AVX-512F and AVX-512CD. The AVX-512ER and AVX-512PF groups are implemented in the Intel Xeon Phi processor x200 only. The AVX-512BW, AVX-512DQ and AVX-512VL groups are implemented only in the Intel Xeon processor."
https://software.intel.com/en-us/blogs/additional-avx-512-in... This used to lead to a PDF with the tables, the PDF is still there but it's a living document which is updated every time, the latest revision was in 2017 but as early as 2014 there was already a split into COMMON-AVX512, MIC-AVX512, CORE-AVX512 with a difference between future Xeon Phi and Xeon processors.
The instruction set info on that page is 2-3 years old, nothing has changed since then.
I've seen those tables at least a year before the KL launch they were also available on Intel's webiste (the blog irrc) at least a year before KL.
I don't know who told you that that information is embargoed.
EDIT: The inital table was here: http://software.intel.com/en-us/blogs/2013/avx-512-instructi... the blog post no longer exists, try archive.is
