AMD EPYC 9474F vs AMD EPYC Embedded 9655: Comparison
What is the difference between EPYC 9474F and EPYC Embedded 9655?
Start with l3 cache, because it is the widest measured gap between them: EPYC 9474F 256 MB against EPYC Embedded 9655 384 MB, 33% in favour of EPYC Embedded 9655. They differ on boost clock too, 4.1 GHz on the EPYC 9474F versus 4.5 GHz on the EPYC Embedded 9655. Tdp is not the same on both, 360 W on the EPYC 9474F versus 400 W on the EPYC Embedded 9655. There is a split on core count as well, 48 cores on the EPYC 9474F versus 96 cores on the EPYC Embedded 9655. They differ on thread count too, 96 threads on the EPYC 9474F versus 192 threads on the EPYC Embedded 9655. Core architecture is not the same on both, Zen 4 "Genoa" on the EPYC 9474F versus Zen 5 on the EPYC Embedded 9655. There is a split on base clock as well, 3.6 GHz on the EPYC 9474F versus 2.6 GHz on the EPYC Embedded 9655. They differ on multi-socket support too, 1P/2P on the EPYC 9474F versus Dual Socket on the EPYC Embedded 9655.
Who each one is for
The EPYC 9474F is the one to take for per-core licensed databases (Oracle, SQL Server) and EDA tools billed per core, though it is the wrong buy for massively parallel batch jobs and cost-per-core-sensitive deployments. Buy the EPYC Embedded 9655 for industrial and embedded system designs and long-lifecycle networking and edge-compute deployments, though it is not the pick for consumer desktop or gaming builds and DIY PC upgrades. Our rating of the EPYC 9474F (8.9/10): the EPYC 9474F is the right call when per-core software licensing makes clock speed worth more than core count.
What EPYC 9474F and EPYC Embedded 9655 have in common
The common ground is wider than the gap: memory channels, socket and ecc support are identical here.
