AMD EPYC 9654P vs AMD EPYC Embedded 9845: Comparison
EPYC 9654P vs EPYC Embedded 9845: the l3 cache difference
On l3 cache the spread is 17%, EPYC 9654P 384 MB against EPYC Embedded 9845 320 MB, so EPYC 9654P takes it. They differ on tdp too, 360 W on the EPYC 9654P versus 390 W on the EPYC Embedded 9845. They differ on core count too, 96 cores on the EPYC 9654P versus 160 cores on the EPYC Embedded 9845. There is a split on thread count as well, 192 threads on the EPYC 9654P versus 320 threads on the EPYC Embedded 9845. There is a split on core architecture as well, Zen 4 "Genoa" on the EPYC 9654P versus Zen 5c on the EPYC Embedded 9845. Base clock is not the same on both, 2.4 GHz on the EPYC 9654P versus 2.1 GHz on the EPYC Embedded 9845. Multi-socket support is not the same on both, 1P on the EPYC 9654P versus Dual Socket on the EPYC Embedded 9845.
Which should you buy, EPYC 9654P or EPYC Embedded 9845?
The EPYC 9654P is the one to take for single-socket hyperscale deployments and cost-optimized dense virtualization, though it is the wrong buy for dual-socket server designs and small-scale deployments. Buy the EPYC Embedded 9845 for industrial and embedded system designs and long-lifecycle networking and edge-compute deployments, though it is not built for consumer desktop or gaming builds and DIY PC upgrades. Our rating of the EPYC 9654P (9/10): the EPYC 9654P delivers the same class-leading core density as the EPYC 9654 at a lower cost for single-socket deployments.
Where the two are identical
The common ground is wider than the gap: boost clock, memory channels, socket and ecc support are identical here.
