AMD EPYC 9254 vs AMD EPYC 9755: Comparison

EPYC 9254 vs EPYC 9755 l3 cache compared

Start with l3 cache, because it is the widest measured gap between them: EPYC 9254 128 MB against EPYC 9755 384 MB, 67% in favour of EPYC 9755. SPECrate® 2017 Integer (base), 1-chip backs the spec sheet up. EPYC 9755 scores 1,410 to 313, 78% clear. Core count is not the same on both, 24 cores on the EPYC 9254 versus 128 cores on the EPYC 9755. There is a split on thread count as well, 48 threads on the EPYC 9254 versus 256 threads on the EPYC 9755. They differ on base clock too, 2.9 GHz on the EPYC 9254 versus 2.7 GHz on the EPYC 9755. Multi-socket support is not the same on both, 1P / 2P on the EPYC 9254 versus Dual Socket on the EPYC 9755.

Who each one is for

Buy the EPYC 9254 for datacenter and cloud compute and virtualization-dense server workloads, though it is not built for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs. The EPYC 9755 suits large-scale enterprise databases and HPC and technical computing at scale, though it is the wrong buy for power-constrained deployments and small server rooms. Our rating of the EPYC 9755 (9.4/10): the EPYC 9755 is AMD's most powerful standard-core EPYC SKU, pairing 128 cores with clocks that make few compromises for organizations that can afford the 500W power budget.

What EPYC 9254 and EPYC 9755 have in common

The common ground is wider than the gap: memory channels, pcie lanes, socket and pcie generation are identical here.

Frequently asked questions

Do the EPYC 9254 and EPYC 9755 differ on boost clock?

Yes. Boost Clock reads Up to 4.15 GHz on the EPYC 9254 versus 4.5 GHz on the EPYC 9755.
