I eagerly await to read any benchmarks of Prime95 AVX512 code on the new skylake-x platform.

From comments in previous posts, the point of contention seems to be the memory components.

No nvidia cards has HBM just yet.

But AMD's Fury/FuryX have it and the benchies are out.

Anyone doing any prime stuff on these cards and are able to comment on any improvement?
