No, Their CPUs as in ones from Intel. Intel has long done a thing in their compilers where they detect the CPU model, and run less optimized code if it isn't Intel. They claim it is because they can't be sure "Other" processors have correctly implemented SSE and other extensions. So Intel Linux is going to run faster on an Intel CPU because it was compiled with ICC.

I don't know much about it, but Intel's clear linux does not use icc this is in their FAQ https://docs.01.org/clearlinux/latest/FAQ/index.html#does-it...
This is trivially easy to defeat, just so you know. If anyone reading is ever in need of optimized math library performance on AMD, just speak to your hardware/cloud vendor; they all know the tricks.
