Recent benchmark testing of the Ubuntu 26.04 LTS development build on AMD EPYC processors, including the latest Turin and Siena series, reveals significant performance enhancements over previous versions. Running on an EPYC 9005 Turin server, initial tests compared Ubuntu 26.04 against Ubuntu 24.04.3 LTS and 25.10, utilizing the Linux 6.18 kernel and GCC 15.2 compiler. The upcoming 26.04 LTS, slated to possibly include the Linux 6.20/7.0 kernel prior to its feature freeze in April, shows encouraging advancements with broader benchmarks anticipated closer to its official release.
Meanwhile, AMD EPYC 8004 “Siena” chips are also showing notable gains. The EPYC 8534P 64-core processor demonstrated improved performance moving from Ubuntu 23.10 with Linux 6.5 to Ubuntu 25.10 featuring the Linux 6.18 kernel and GCC 15.2. The single-socket Siena series, designed for energy efficiency, supports up to 64 cores and six memory channels, positioning it as a cost-effective solution for modern server deployments with further optimizations expected with Ubuntu 26.04 LTS.
In a similar vein, Intel Xeon 6780E “Sierra Forest” processors have seen a 14% enhancement in Linux performance since their introduction in June 2024. Testing compared the default Ubuntu 24.04 LTS setup to the current Ubuntu 26.04 LTS development snapshot, highlighting substantial optimization through Linux’s software ecosystem. These strides are consistent within the broader context of Intel and AMD’s ongoing performance evolution.
