As part of my end-of-year benchmarking and various historical comparisons, over the holidays I was curious to take a look at how the mature AMD EPYC 9004 "Genoa" performance has evolved over the past two years under Linux. Going off benchmarks I ran back at the end of 2022 on the same AMD Titanite EPYC reference server platform for two EPYC 9654 Genoa processors, I repeated the same tests using the newest releases of Intel Clear Linux and Ubuntu Linux for seeing how the performance has evolved.

With the AMD Titanite reference server running two AMD EPYC 9654 96-core Genoa processors, 24 x 64GB DDR5-4800 memory, and 800GB Intel Optane DC P4800X 800GB (SSDPF21Q800GB) NVMe SSD, I compared the performance of the prior end of 2022 benchmarks of Intel Clear Linux 37860 and Ubuntu 22.10 to that of running the latest Clear Linux 42790 and Ubuntu 24.10 on the same AMD EPYC server.

The two year software comparison on Clear Linux meant going from Linux 6.1 to Linux 6.12, GCC 12.2.1 to GCC 14.2.1, Python 3.11 to Python 3.13, OpenJDK 18 to 21 for Java, and a variety of other software package updates. Plus all of the Intel performance optimizations that their engineers have been pushing into the distribution over the past two years.
