Last week we received the AMD EPYC 7601 32 core / 64 thread processor for testing at Phoronix with the Tyan Transport SX TN70A-B8026 2U server. Since then I've had the pleasure of putting this Zen workstation/server processor through its paces. I am still early in the testing process with many more interesting benchmarks to come, but today are some initial numbers of the AMD EPYC 7601 compared to various Intel Xeon CPUs while running Ubuntu Linux.
