AMD EPYC 9565 vs AMD EPYC Embedded 9845: Comparison
What is the difference between EPYC 9565 and EPYC Embedded 9845?
Start with l3 cache, because it is the widest measured gap between them: EPYC 9565 384 MB against EPYC Embedded 9845 320 MB, 17% in favour of EPYC 9565. Boost clock is not the same on both, Up to 4.3 GHz on the EPYC 9565 versus 3.7 GHz on the EPYC Embedded 9845. There is a split on tdp as well, 400 W on the EPYC 9565 versus 390 W on the EPYC Embedded 9845. They differ on release year too, 2024 on the EPYC 9565 versus 2025 on the EPYC Embedded 9845. There is a split on core count as well, 72 cores on the EPYC 9565 versus 160 cores on the EPYC Embedded 9845. They differ on thread count too, 144 threads on the EPYC 9565 versus 320 threads on the EPYC Embedded 9845. Base clock is not the same on both, 3.15 GHz on the EPYC 9565 versus 2.1 GHz on the EPYC Embedded 9845. There is a split on multi-socket support as well, 1P / 2P on the EPYC 9565 versus Dual Socket on the EPYC Embedded 9845. The max memory speed figures are near enough to ignore, 6400 MT/s on the EPYC 9565 versus 6000 MT/s on the EPYC Embedded 9845.
Which should you buy, EPYC 9565 or EPYC Embedded 9845?
The EPYC 9565 is the one to take for datacenter and cloud compute and virtualization-dense server workloads, though it is the wrong buy for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs. Buy the EPYC Embedded 9845 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.
What EPYC 9565 and EPYC Embedded 9845 have in common
Where they agree, they agree completely, memory channels, pcie lanes, socket and pcie generation included, so the decision does not turn on any of those.

Which one should you pick?
Choose 9565 if you want the higher L3 cache (384 MB vs 320 MB), the higher memory channels (12 channels vs 12 channels) and the higher PCIe lanes (128 lanes vs 128 lanes).
Choose 9845 if you already have it on hand or find it at a lower price.
