I recently was wondering how much the AVX512 helped. I figured it would be pretty noticeable on FP heavy workloads like say Spec.org's CPU2016. I was pretty surprised that the Xeon 5118 (24c@2.3GHz with 1 AVX512) gets a FP score of 946. The Xeon 6126 (24c@2.6Ghz with 2 AVX512) gets a FP score of 1090. So 13% clock rate gets them a 15% better score. For such FP heavy codes I was pretty shocked a second FP unit only gains them a few %. Not a particularly impressive improvement since the cost to a dual socket node adds $1,000.
