AMD EPYC 9755 Delivers Decisive Performance Leadership Over Xeon 6 Granite Rapids With Nearly 500 Benchmarks

Back in December I carried out some fresh benchmarks of the Intel Xeon 6980P vs. AMD EPYC 9755 for these competing 128 core server processors using the latest Linux software stack before closing out 2025. That was done with nearly 200 benchmarks and the AMD EPYC Turin Zen 5 processor delivered terrific performance as we have come to enjoy out of the 5th Gen EPYC line-up over the past year and several months. Since then I have ratcheted up the benchmarks with nearly 500 benchmarks between the AMD EPYC 9755 and Intel Xeon 6980P processors for an even more comprehensive look at these CPUs atop Linux 6.18 LTS.
