AMD EPYC 9755 / 9575F / 9965 Benchmarks Show Dominating Performance
With the QuantLib open-source quantitative finance software there were very nice generational gains made with the EPYC 9005 series processors tested and the EPYC 9755 and EPYC 9965 processors both outperforming the new Granite Rapids flagship model. The EPYC 9965 is consistently looking like the sweet spot for the best performance-per-Watt as well as performance per dollar.
Across a range of HPC workloads the AMD EPYC Turin processors were delivering great performance.
With the memory bandwidth intensive HPCG benchmark the MRDIMMs allowed the Xeon 6980P to secure a dominating first place finish. But on a performance-per-Watt basis was comparable among the EPYC Turin and Granite Rapids processors. On a CPU cost basis the AMD EPYC Turin processors were leading with select models. The MRDIMM pricing is also likely significantly more than DDR5-6000/6400 memory modules but so far I haven't seen any MRDIMM pricing data from Micron.
With some of the NASA Parallel Benchmarks there were some wins for the Xeon 6980P in raw performance, particularly when using MRDIMM memory. But the Xeon 6980P quickly falls behind when looking at the performance-per-dollar.
Aside from the exceptions in workloads favoring MRDIMMs, the EPYC Turin processors provided typically leading performance and then commanding performance-per-dollar and great power efficiency.
Incompact3D was another benchmark where MRDIMMs helped Granite Rapids with raw performance.
