Oh, Geekbench which can be 'won' by implementing a single encryption instruction in hardware.
Still, even looking at the scores for less broken sub benchmarks, like (possibly) lua and dijkstra show a %50 increase in performance from Westmere to Skylake for the same frequency, which is more than I was expecting. And skylake should potentially clock much higher although I believe the top is currently still 4ghz.
Of course for anything that can take advantage AVX2 (or AVX3 for xeons) skylake would smoke the old xeon.
