Phoronix has published some numbers of the EPYC 7601 32-core/64-thread processor compared to various Intel Xeon CPUs while running Ubuntu Linux: benchmarks suggest that AMD is “certainly back in the game for high-end server performance,” showing great multi-threaded workload performance, even outclassing a dual Xeon Gold 6138 configuration offering more cores/threads but costing $1000 more. Thanks grtitan.



It looks like EPYC is on the right track in being able to deliver very capable AMD Linux server performance for threaded workloads. Besides two Xeon Gold 6138 processors costing more than the EPYC 7601, each CPU has a 125-watt TDP (thus 250 watt total) while the single EPYC 7601 has just a 180 Watt TDP. For memory-bound workloads, the EPYC 7601 also has the advantage of supporting eight memory channels.
