AMD Zen 6 SMT Proves Very Advantageous Even For 256 Core EPYC 9996

With the now-shipping AMD EPYC 9006 'Venice' SP7 server processors sporting up to 256 Zen 6 cores per socket, or 512 cores in a 2P configuration, questions arose about SMT's value on these increasingly high core count processors. Benchmark tests confirm SMT on AMD Zen 6 remains worthwhile from both performance and power perspectives.

The tests specifically examined SMT impact on the 256-core EPYC 9996 and the 96-core high frequency EPYC 9686F processors, demonstrating continued benefits even as core counts increase significantly.
