Recent benchmarking by Phoronix has highlighted the performance improvements of AMD EPYC 9004 "Genoa" processors under Linux over the past two years. The tests were conducted on an AMD Titanite EPYC reference server equipped with dual EPYC 9654 processors, utilizing both Intel Clear Linux and Ubuntu Linux. The benchmarks compared performance from late 2022 to the latest releases in late 2024, revealing significant enhancements due to software updates and Intel's performance optimizations. The transition from Clear Linux 37860 to 42790 and Ubuntu 22.10 to 24.10 involved updates in the Linux kernel, GCC, Python, and Java, among other software packages. Notably, Clear Linux employs a "performance" governor by default, while Ubuntu uses the "schedutil" governor, which may affect performance outcomes. The benchmarking aimed to assess how these optimizations have influenced the performance of AMD EPYC processors in a competitive landscape between Intel-optimized Clear Linux and Ubuntu.
