Ubuntu 26.10 amd64v3 Packages Provide Some Additional Uplift On AMD EPYC
In addition to Ubuntu 26.10 itself delivering some nice performance gains on Ubuntu 26.10 for AMD EPYC servers and other hardware, the optional and currently-unofficial amd64v3 package archive also provides additional performance uplift. Here is a look quantifying the performance impact of amd64v3 packages on AMD EPYC 9005 series servers.
Additional performance benefits are available through Ubuntu 26.10's amd64v3 package archive, which can be installed on AMD EPYC 9005 series servers. While Canonical has not officially endorsed the amd64v3 packages as alternatives to generic amd64 binaries, my tests show notable performance improvements. The benchmarks utilized a Gigabyte MZ33-AR1 system equipped with an AMD EPYC 9555P 64-core processor, comparing the default amd64 packages with the amd64v3 packages.
