Right out of the gate Intel's Clear Linux was picking up wins over Ubuntu on this AMD EPYC Rome server. Some of the wins though aren't by the magnitude we see on Intel hardware due to Clear's extensive AVX optimizations and other tuning for Intel microarchitectures.

There were also some losses or cases of Clear Linux just tieing with Ubuntu 19.04/19.10, but generally was standing well on this AMD EPYC 7742 2P server.
