AMD EPYC 8635P "Sorano" Benchmarks: Significant Upgrade Opportunity For EPYC 8004 Servers
Given the telco emphasis with the EPYC 8004/8005 series, starting off the benchmarking with OCUDU as the Linux Foundation project backed by many vendors for Open RAN CU/DU implementations, there was a 28% improvement going from the top-end EPYC 8004 to EPYC 8005 processor as an upgrade on the otherwise same server.
On a performance-per-Watt basis it was similar between these two EPYC processors, to not much surprise given the higher default TDP of the EPYC 8635P.
When looking at the per-thread performance with OCUDU we see the huge uplift out of the new top-end Socket SP6 CPU. The upgrade from Zen 4 to Zen 5 paired with a larger L3 cache and higher clock speeds makes for a very nice upgrade story at the top-end from the EPYC 8004 to EPYC 8005 series.
OCUDU is an evolution from the earlier srsRAN software defined radio project. Even testing that older codebase was showing the huge per-thread improvement from these top-end Siena to Sorano processors.
For the GNU Radio software for software-defined radios and signal processing, there was again huge generational gains from Siena to Sorano.
And again with LuaRadio was also excellent generational gains from the EPYC 8534P to EPYC 8635P out of the same server platform.
The performance-per-Watt tended to be similar to Siena or in some cases coming out ahead in the best performance-per-Watt. It's too bad there aren't any Intel Xeon 6700 review samples to toss in the testing mix but at least for AMD EPYC Sorano the gen-on-gen performance gains are substantial.
