A Curious Look At Eight Core Server CPU Performance From Intel Xeon Haswell To AMD EPYC Rome
First up was the HPCG internal I/O benchmark showing the significant gains compared to the older Intel platforms. Meanwhile going from the EPYC 7251 to 7262 was a 5% increase in performance. For the Xeon E5-1680 v3 as the principal 8c/16t Haswell comparison target to the EPYC 7232P was a 36% increase in performance or the EPYC 7262 with its slightly higher clock frequencies and much larger L3 cache delivered 2.08x the performance of the E5-1680 v3.
HPCG is internally I/O bound while with the NAS Parallel Benchmarks we are able to see Rome really flexing its power as a significant upgrade over the older Intel Xeon platforms. In the case of FT.C, going from the previous generation EPYC 7251 to 7232P yielded even a 20% improvement.
As one would expect, modern AMD EPYC Rome processors perform much faster than the older Intel Haswell era server platforms that some small businesses may still be relying upon.
