AMD EPYC 9255 vs AMD EPYC Embedded 9555: Comparison
EPYC 9255 vs EPYC Embedded 9555 l3 cache compared
Start with l3 cache, because it is the widest measured gap between them: EPYC 9255 128 MB against EPYC Embedded 9555 256 MB, 50% in favour of EPYC Embedded 9555. They differ on boost clock too, 4.05 GHz on the EPYC 9255 versus 4.4 GHz on the EPYC Embedded 9555. Tdp is not the same on both, 200 W on the EPYC 9255 versus 360 W on the EPYC Embedded 9555. There is a split on core count as well, 24 cores on the EPYC 9255 versus 64 cores on the EPYC Embedded 9555. They differ on thread count too, 48 threads on the EPYC 9255 versus 128 threads on the EPYC Embedded 9555. Core architecture is not the same on both, Zen 5 "Turin" on the EPYC 9255 versus Zen 5 on the EPYC Embedded 9555.
Which should you buy, EPYC 9255 or EPYC Embedded 9555?
The EPYC 9255 is the one to take for general-purpose virtualization hosts and application servers, though it is not the pick for maximum core density workloads and large-scale hyperscale deployments. Buy the EPYC Embedded 9555 for industrial and embedded system designs and long-lifecycle networking and edge-compute deployments, though it is not built for consumer desktop or gaming builds and DIY PC upgrades. Our rating of the EPYC 9255 (8.6/10): the EPYC 9255 is a solid general-purpose choice for servers that need more than entry-level core count without going all the way to AMD's high-density SKUs.
What EPYC 9255 and EPYC Embedded 9555 have in common
The common ground is wider than the gap: base clock, socket and multi-socket support are identical here.
