AMD EPYC 4584PX vs AMD EPYC Embedded 4345P: Comparison
What is the difference between EPYC 4584PX and EPYC Embedded 4345P?
Start with l3 cache, because it is the widest measured gap between them: EPYC 4584PX 128 MB against EPYC Embedded 4345P 32 MB, 75% in favour of EPYC 4584PX. They differ on boost clock too, Up to 5.7 GHz on the EPYC 4584PX versus 5.5 GHz on the EPYC Embedded 4345P. Tdp is not the same on both, 120 W on the EPYC 4584PX versus 65 W on the EPYC Embedded 4345P. There is a split on core count as well, 16 cores on the EPYC 4584PX versus 8 cores on the EPYC Embedded 4345P. They differ on thread count too, 32 threads on the EPYC 4584PX versus 16 threads on the EPYC Embedded 4345P. Base clock is not the same on both, 4.2 GHz on the EPYC 4584PX versus 3.8 GHz on the EPYC Embedded 4345P.
Who each one is for
The EPYC 4584PX 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 4345P 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 4584PX and EPYC Embedded 4345P have in common
Everything else lines up. Pcie lanes, socket and multi-socket support read the same on both, so those are not worth weighing.

Which one should you pick?
Choose 4584PX if you want the higher L3 cache (128 MB vs 32 MB) and the higher PCIe lanes (28 lanes vs 28 lanes).
Choose 4345P if you already have it on hand or find it at a lower price.
