AMD EPYC 9124P vs AMD EPYC Embedded 9745: Comparison
What is the difference between EPYC 9124P and EPYC Embedded 9745?
L3 cache is where these two genuinely part company, EPYC 9124P 64 MB against EPYC Embedded 9745 256 MB, a 75% lead for EPYC Embedded 9745. There is a split on tdp as well, 200 W on the EPYC 9124P versus 400 W on the EPYC Embedded 9745. There is a split on core count as well, 16 cores on the EPYC 9124P versus 128 cores on the EPYC Embedded 9745. They differ on thread count too, 32 threads on the EPYC 9124P versus 256 threads on the EPYC Embedded 9745. There is a split on core architecture as well, Zen 4 "Genoa" on the EPYC 9124P versus Zen 5c on the EPYC Embedded 9745. They differ on base clock too, 3.0 GHz on the EPYC 9124P versus 2.4 GHz on the EPYC Embedded 9745. They differ on multi-socket support too, 1P on the EPYC 9124P versus Dual Socket on the EPYC Embedded 9745.
Which should you buy, EPYC 9124P or EPYC Embedded 9745?
The EPYC 9124P is the one to take 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. Buy the EPYC Embedded 9745 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.
What EPYC 9124P and EPYC Embedded 9745 have in common
The common ground is wider than the gap: boost clock, memory channels, socket and ecc support are identical here.
