Notes
We have updated Ubuntu to 20.04.2 LTS, featuring Linux 5.8, to better reflect performance on a newer build. With that being the case, we have benchmarked the Intel Xeon Platinum 8380 against its direct predecessor, Xeon Platinum 8280, and also rebenchmarked AMD's third-generation Epyc 7713 (64C128T) and high-frequency 75F3 (32C64T) processors. All were tested in a 2P formation.
It is incredibly difficult to test server processor performance without having access to racks upon racks, to reflect real-world use where networking, memory infrastructure and heavily-tuned software play pivotal parts in defining overall speed and service-level agreement parameters. Customers wanting to purchase a significant volume will likely evaluate these chips in their own environment, on their own software, but we don't have that luxury.
Appreciating we're looking at compute throughput first and foremost, mostly in isolation, we use a subset of the excellent Phoronix Test Suite to measure server performance. It ought to provide a glimpse into how far Intel has come from one generation to the next and also offer insight into comparative performance against AMD's latest.
