No, I don’t expect a huge difference in per-core performance either, though I haven’t compared benchmarks yet. Niagara's Skylake CPUs already supported #AXV512 (they even waited a bit for Skylake to be released) which gave a good #performance boost over AVX2. But core-density is the new MHz. 😉
Though you may want to recompile your code if you’re currently directly linking to #MKL since Trillium has AMD CPUs. BLIS is faster on those.
