The QuantLib quantitative finance software continued showing the EPYC 9965 scaling past the EPYC 9755 processors but for the Xeon 6780E lacking AVX-512 and the 144 cores fighting for eight channels of DDR5-6400 compared to Granite Rapids AP with 12 channels of MRDIMM-8800 memory, the Sierra Forest processors were behind the Xeon 6980 2P performance here. The AMD EPYC Turin CPUs led in both performance and power efficiency.
Both the AMD EPYC and Intel Xeon server processors have evolved quite a bit with the upstream Linux software improvements over the past 1~2 years.
The AMD EPYC 9965 192-core processors continue performing very strong while we know with next-gen EPYC Venice they will be pushing up to 256 cores per socket.
