AMD EPYC On Ubuntu 18.10 Putting Up A Stronger Fight Against Xeon Gold

The Parboil and Rodinia benchmarks were a toss-up between the dual Xeon Gold 6138 and EPYC 7601 servers. These OpenMP-based tests scale very well with increasing thread counts, but the EPYC 7601 32-core / 64-thread CPU is able to give the Intel 40-core / 80-thread combo stiff competition in many of the tests. These results are certainly much tighter than we have seen in some of the past comparisons.

In some demanding scientific tests, the extra cores/threads and Intel's greater IPC against current-generation EPYC CPUs does still let it have a hefty lead with the servers/CPUs tested.

With x265 video encoding, the EPYC 7601 carries an incredibly tight advantage.
