A Curious Look At Eight Core Server CPU Performance From Intel Xeon Haswell To AMD EPYC Rome

The x265 video encode benchmark shows how much progress has been made from AMD EPYC Naples to Rome.

With the EPYC 7262 it can build the mainline Linux kernel in a minute and a half, or about saving a half minute per kernel build in comparison to the older 8c/16t Haswell.

For some compilation workloads, the Xeon Haswell E5 CPUs were outperforming the previous-generation EPYC 7251 but that is not the case with Rome.

One of the few areas where the old Haswell CPUs and lower-end Kabylake CPUs were comparable to Rome was with the Numpy Python numerical computing performance. But at least we are seeing AMD developers this year making more Linux software optimizations around Glibc and other components to hopefully increase the competition against Intel in areas like this.
