AMD EPYC 9655 Benchmarks Show The Terrific Generational Gains With 5th Gen EPYC
While not as much scaling from single to dual socket in the database tests due to NUMA locality and the Granite Rapids server doing worse in the 2P configuration in said workloads, these tests do show the significant uplift from Zen 4 to Zen 5 for servers at the same 96 core count.
With RocksDB going from the EPYC 9654 2P to EPYC 9655 2P meant more than 1.4x the performance and 1.25x the performance per Watt even with the same core count.
The AMG HPC benchmark is one of the cases where Xeon Granite Rapids with MRDIMMs can perform very well. But the 96-core EPYC 9655 didn't fall too far behind the 128-core Xeon 6980P when using DDR5-6400 memory. When it comes to generational uplift for the 96-core AMD server processors, the EPYC 9755 delivered around 1.4x the performance and 1.22x the performance-per-Watt of the EPYC 9654.
The AMD EPYC 9655 was delivering very significant uplift to the raw performance and power efficiency over the prior flagship EPYC 9654 processor across a range of HPC workloads.
There were very worthwhile improvements to performance and power efficiency out of the AMD EPYC 9655 compared to the EPYC 9654. The ability to make this generational upgrade while keeping to the same Socket SP5 server platform also yields significant TCO savings.
