AMD EPYC 9745 vs AMD EPYC Embedded 9655P: Comparison
EPYC 9745 vs EPYC Embedded 9655P: the boost clock difference
The first real difference is boost clock: EPYC 9745 4.0 GHz against EPYC Embedded 9655P 4.5 GHz. Core count is not the same on both, 128 cores on the EPYC 9745 versus 96 cores on the EPYC Embedded 9655P. Thread count is not the same on both, 256 threads on the EPYC 9745 versus 192 threads on the EPYC Embedded 9655P. They differ on core architecture too, Zen 5c "Turin Dense" on the EPYC 9745 versus Zen 5 on the EPYC Embedded 9655P. Base clock is not the same on both, 2.4 GHz on the EPYC 9745 versus 2.6 GHz on the EPYC Embedded 9655P. They differ on multi-socket support too, 1P/2P on the EPYC 9745 versus Single Socket Only on the EPYC Embedded 9655P.
EPYC 9745 vs EPYC Embedded 9655P: which one fits your build
The EPYC 9745 suits hyperscale cloud and VM hosting and container-dense Kubernetes nodes, though it is not the pick for small server deployments and per-core licensed software. Buy the EPYC Embedded 9655P for industrial and embedded system designs and long-lifecycle networking and edge-compute deployments, though it is the wrong buy for consumer desktop or gaming builds and DIY PC upgrades. Our rating of the EPYC 9745 (9.1/10): the EPYC 9745 delivers 128-core density at a more power-conscious 400W, making it the efficiency-minded pick for hyperscale deployments.
Where the two are identical
The common ground is wider than the gap: tdp, l3 cache, memory channels, socket and ecc support are identical here.
