For the HPC benchmarks whether Simultaneous Multi-Threading is beneficial can be more hotly contested. Here it largely comes down to the workload, whether MPI is being used and/or OpenMP also being used as well, and how memory bandwidth intensive are the workloads with having 128 cores and twelve channel DDR5-6000 memory.
The QuantLib quantitative finance software saw some benefit out of SMT.
The NPB benchmarks were mixed for how much the benefited or not from SMT on this 128-core Zen 5 processor.
