AMD EPYC 9124P vs AMD EPYC Embedded 9655: Comparison
What is the difference between EPYC 9124P and EPYC Embedded 9655?
Start with l3 cache, because it is the widest measured gap between them: EPYC 9124P 64 MB against EPYC Embedded 9655 384 MB, 83% in favour of EPYC Embedded 9655. There is a split on boost clock as well, 3.7 GHz on the EPYC 9124P versus 4.5 GHz on the EPYC Embedded 9655. They differ on tdp too, 200 W on the EPYC 9124P versus 400 W on the EPYC Embedded 9655. Core count is not the same on both, 16 cores on the EPYC 9124P versus 96 cores on the EPYC Embedded 9655. There is a split on thread count as well, 32 threads on the EPYC 9124P versus 192 threads on the EPYC Embedded 9655. They differ on core architecture too, Zen 4 "Genoa" on the EPYC 9124P versus Zen 5 on the EPYC Embedded 9655. Base clock is not the same on both, 3.0 GHz on the EPYC 9124P versus 2.6 GHz on the EPYC Embedded 9655. There is a split on multi-socket support as well, 1P on the EPYC 9124P versus Dual Socket on the EPYC Embedded 9655.
Who each one is for
Buy the EPYC 9124P for single-socket server deployments and cost-conscious data center builds, though it is the wrong buy for dual-socket server designs and maximum core density needs. The EPYC Embedded 9655 suits 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 9124P (8.5/10): the EPYC 9124P is a smart cost-saver for any deployment that was only ever going to use one socket.
What EPYC 9124P and EPYC Embedded 9655 have in common
Everything else lines up. Memory channels, socket and ecc support read the same on both, so those are not worth weighing.
