AMD EPYC 9124P vs AMD EPYC Embedded 9845: Comparison
EPYC 9124P vs EPYC Embedded 9845 l3 cache compared
The gap that matters here is l3 cache: EPYC 9124P 64 MB against EPYC Embedded 9845 320 MB, which puts EPYC Embedded 9845 80% ahead. Tdp is not the same on both, 200 W on the EPYC 9124P versus 390 W on the EPYC Embedded 9845. They differ on core count too, 16 cores on the EPYC 9124P versus 160 cores on the EPYC Embedded 9845. There is a split on thread count as well, 32 threads on the EPYC 9124P versus 320 threads on the EPYC Embedded 9845. Core architecture is not the same on both, Zen 4 "Genoa" on the EPYC 9124P versus Zen 5c on the EPYC Embedded 9845. They differ on base clock too, 3.0 GHz on the EPYC 9124P versus 2.1 GHz on the EPYC Embedded 9845. There is a split on multi-socket support as well, 1P on the EPYC 9124P versus Dual Socket on the EPYC Embedded 9845.
Which should you buy, EPYC 9124P or EPYC Embedded 9845?
Buy the EPYC 9124P for single-socket server deployments and cost-conscious data center builds, though it is not built for dual-socket server designs and maximum core density needs. The EPYC Embedded 9845 is the one to take 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 9124P (8.5/10): the EPYC 9124P is a smart cost-saver for any deployment that was only ever going to use one socket.
Where the two are identical
Where they agree, they agree completely, boost clock, memory channels, socket and ecc support included, so the decision does not turn on any of those.
