AMD EPYC 4584PX vs AMD EPYC Embedded 4545P: Comparison
EPYC 4584PX vs EPYC Embedded 4545P: the l3 cache difference
L3 cache is where these two genuinely part company, EPYC 4584PX 128 MB against EPYC Embedded 4545P 64 MB, a 50% lead for EPYC 4584PX. They differ on boost clock too, Up to 5.7 GHz on the EPYC 4584PX versus 5.4 GHz on the EPYC Embedded 4545P. They differ on tdp too, 120 W on the EPYC 4584PX versus 65 W on the EPYC Embedded 4545P. Base clock is not the same on both, 4.2 GHz on the EPYC 4584PX versus 3 GHz on the EPYC Embedded 4545P.
EPYC 4584PX vs EPYC Embedded 4545P: which one fits your build
The EPYC 4584PX suits 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. The EPYC Embedded 4545P is the one to take 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 4545P have in common
Everything else lines up. Pcie lanes, core count, thread count, 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 64 MB) and the higher PCIe lanes (28 lanes vs 28 lanes).
Choose 4545P if you already have it on hand or find it at a lower price.
