As has been stated on a number of review sites, AVX 512 performance on the 6/8 core Skylake-X is compromised.
Only on the 10 core, the present hardware is fully enabled.
Would Intel be so kind as to provide in depth detail of what the performance difference means ?
From the vague information available it seems one of 2(3?) AVX 512 ports is disabled (port 5).
Can we get more detailed information, which ports are used for AVX 512 ?
What AVX 512 instructions can the ports execute, do they have 512-bit data paths to registers/cache ?
How is AVX 512 gather affected regarding the 6/8 core versus 10 core ?
A similar drawing as below for AVX2 would be appreciated.
