AMD EPYC 9355 vs AMD EPYC Embedded 9655: Comparison
EPYC 9355 vs EPYC Embedded 9655 l3 cache compared
L3 cache is where these two genuinely part company, EPYC 9355 256 MB against EPYC Embedded 9655 384 MB, a 33% lead for EPYC Embedded 9655. There is a split on boost clock as well, 4.4 GHz on the EPYC 9355 versus 4.5 GHz on the EPYC Embedded 9655. There is a split on tdp as well, 280 W on the EPYC 9355 versus 400 W on the EPYC Embedded 9655. They differ on core count too, 32 cores on the EPYC 9355 versus 96 cores on the EPYC Embedded 9655. There is a split on thread count as well, 64 threads on the EPYC 9355 versus 192 threads on the EPYC Embedded 9655. They differ on core architecture too, Zen 5 "Turin" on the EPYC 9355 versus Zen 5 on the EPYC Embedded 9655. They differ on base clock too, 3.55 GHz on the EPYC 9355 versus 2.6 GHz on the EPYC Embedded 9655. Multi-socket support is not the same on both, 1P/2P on the EPYC 9355 versus Dual Socket on the EPYC Embedded 9655.
Which should you buy, EPYC 9355 or EPYC Embedded 9655?
The EPYC 9355 is the one to take for 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. Buy the EPYC Embedded 9655 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 9655 have in common
The common ground is wider than the gap: memory channels, socket and ecc support are identical here.
