The AMD EPYC 9754S is designed for HPC workloads with SMT disabled, delivering 128 cores and 128 threads with a default TDP of 360W.
Last year AMD expanded its server CPU line with 4th Gen EPYC. While the 128-core, 256-thread EPYC 9754 took top billing, just under it on the SKU matrix is the AMD EPYC 9754S. The difference between the two chips is simple, yet dramatic. The 9754S has Simultaneous Multithreading (SMT) disabled. This means the 9754S delivers the same 128 cores as the 9754, but with SMT disabled, just 128 threads, compared to 256. This change brings about a nice discount for customers disabling SMT already.
