AMD EPYC 9755 / 9575F / 9965 Benchmarks Show Dominating Performance
Across more than 140 benchmarks the AMD EPYC 9005 series processors were delivering great performance, power efficiency, and value. Those interested can see all 140 benchmarks via this result file.
For the geo mean the calculations were done after dropping the Intel Xeon 6 Sierra Forest CPUs since with that firmware on the reference server there were hangs encountered in a few of the HPC/MPI benchmarks. So to avoid losing those in the overall mean, the Sierra Forest CPUs were dropped when generating the geo mean.
The tested AMD EPYC 9575F high frequency Turin 64-core processor, EPYC 9755 128-core Turin processor, and EPYC 9965 192-core Turin Dense processors dominated across the wide variety of server / technical computing / HPC workloads tested. The dual 128-core EPYC 9755 Turin processor was 40% faster than the dual Xeon 6980P Granite Rapids server with MRDIMMs. Even a single EPYC 9755 (and EPYC 9965) effectively matched the dual Xeon 6980P processors in this larger selection of benchmarks than what was initially run for Granite Rapids.
The EPYC 9755 flagship Turin (non-dense) processor was 1.55x the performance of the 96-core EPYC 9654 Genoa processor. The EPYC 9965 192-core Turin Dense processor was 45% faster as well than the dual EPYC 9754 flagship Bergamo processor. These are some wild generational improvements.
Across all of the benchmarks, the EPYC 9965 had an average CPU power consumption of 275 Watts and a peak of 461 Watts, the EPYC 9575F had an average of 313 Watts and a peak of 403 Watts, and the EPYC 9755 had an average power consumption of 324 Watts with a peak of 500 Watts. The Xeon 6980P meanwhile had a 322 Watt average and 547 Watt peak.
The EPYC 9965 consumed 32% more power than the EPYC 9654 on average but still yielded better power efficiency thanks to achieving 1.55x the generational performance. Similarly, the EPYC 9965 Turin Dense processor saw 22% higher CPU power use on average than the EPYC 9754 Bergamo but with 192 vs. 128 cores and enjoying 1.45x the generational performance.
The tested AMD EPYC 9005 series processors delivered excellent generational performance gains over the EPYC 9004 series, leading performance over the new Xeon 6900P Granite Rapids series, and completing the trifecta is leading performance-per-dollar as well. The EPYC 9755 has a list price of $12,984 and the EPYC 9965 192-core processor has a list price of $14,813 while the Xeon 6980P has a list price of $17,800. There is significant savings in going for EPYC 9005 series. On a TCO basis the EPYC 9005 series is likely even more compelling if otherwise going the MRDIMM route with Granite Rapids likely being much more expensive although I haven't seen any MRDIMM pricing yet. With the EPYC 9005 series continuing to use Socket SP5, there will likely be more robust availability and competitive pricing with able to support EPYC 9005 with a BIOS update -- although for the 500 Watt SKUs they might not be all validated across existing SP5 servers/motherboards depending upon power and cooling. We'll see how the pricing and availability between AMD EPYC Turin and Intel Xeon Granite Rapids plays out over the weeks/months ahead.
I have been really happy with the AMD EPYC 9004 Genoa(X) / Bergamo processors but now AMD has really delivered exceptional performance and efficiency gains with EPYC 9005 Turin processors. Intel had an exciting run of a few weeks with Granite Rapids but now EPYC Turin is ready for some very competitive -- and often times dominating -- action. The advantages of Granite Rapids remain for very memory bandwidth intensive workloads where MRDIMM 8800 memory modules can be of much benefit, the few select areas where the Intel accelerators can be of benefit like telco, and then the AI workloads that are able to leverage Advanced Matrix Extensions (AMX). But for common server workloads and especially other HPC/technical computing environments, the AMD EPYC 9005 series is some fiery competition.
