AMD EPYC 7543 vs AMD EPYC Embedded 7452: Comparison
EPYC 7543 vs EPYC Embedded 7452: the l3 cache difference
Start with l3 cache, because it is the widest measured gap between them: EPYC 7543 256 MB against EPYC Embedded 7452 128 MB, 50% in favour of EPYC 7543. There is a split on boost clock as well, Up to 3.7 GHz on the EPYC 7543 versus 3.35 GHz on the EPYC Embedded 7452. They differ on tdp too, 225 W on the EPYC 7543 versus 155 W on the EPYC Embedded 7452. Base clock is not the same on both, 2.8 GHz on the EPYC 7543 versus 2.35 GHz on the EPYC Embedded 7452.
Who each one is for
The EPYC 7543 suits datacenter and cloud compute and virtualization-dense server workloads, though it is not built for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs. The EPYC Embedded 7452 is the one to take 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.
What EPYC 7543 and EPYC Embedded 7452 have in common
Everything else lines up. Pcie lanes, core count, thread count and socket read the same on both, so those are not worth weighing.

Which one should you pick?
Choose 7543 if you want the higher L3 cache (256 MB vs 128 MB) and the higher PCIe lanes (128 lanes vs 128 lanes).
Choose 7452 if you already have it on hand or find it at a lower price.
