AMD EPYC 9355 vs AMD EPYC Embedded 9965: Comparison
EPYC 9355 vs EPYC Embedded 9965 l3 cache compared
Start with l3 cache, because it is the widest measured gap between them: EPYC 9355 256 MB against EPYC Embedded 9965 384 MB, 33% in favour of EPYC Embedded 9965. Boost clock is not the same on both, 4.4 GHz on the EPYC 9355 versus 3.7 GHz on the EPYC Embedded 9965. There is a split on tdp as well, 280 W on the EPYC 9355 versus 500 W on the EPYC Embedded 9965. They differ on core count too, 32 cores on the EPYC 9355 versus 192 cores on the EPYC Embedded 9965. Thread count is not the same on both, 64 threads on the EPYC 9355 versus 384 threads on the EPYC Embedded 9965. There is a split on core architecture as well, Zen 5 "Turin" on the EPYC 9355 versus Zen 5c on the EPYC Embedded 9965. They differ on base clock too, 3.55 GHz on the EPYC 9355 versus 2.25 GHz on the EPYC Embedded 9965. Multi-socket support is not the same on both, 1P/2P on the EPYC 9355 versus Dual Socket on the EPYC Embedded 9965.
Who each one is for
The EPYC 9355 suits small to mid-size server deployments and edge infrastructure, though it is not the pick for maximum core density workloads and large-scale hyperscale deployments. The EPYC Embedded 9965 is the one to take 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 9355 (8.4/10): the EPYC 9355 is a sensible entry point into the EPYC platform for smaller deployments that still want server-grade memory bandwidth and reliability.
What EPYC 9355 and EPYC Embedded 9965 have in common
Where they agree, they agree completely, memory channels, socket and ecc support included, so the decision does not turn on any of those.
