AMD EPYC 7543 vs AMD EPYC Embedded 7402: Comparison
EPYC 7543 vs EPYC Embedded 7402: the l3 cache difference
On l3 cache the spread is 50%, EPYC 7543 256 MB against EPYC Embedded 7402 128 MB, so EPYC 7543 takes it. They differ on boost clock too, Up to 3.7 GHz on the EPYC 7543 versus 3.35 GHz on the EPYC Embedded 7402. They differ on tdp too, 225 W on the EPYC 7543 versus 180 W on the EPYC Embedded 7402. There is a split on core count as well, 32 cores on the EPYC 7543 versus 24 cores on the EPYC Embedded 7402. There is a split on thread count as well, 64 threads on the EPYC 7543 versus 48 threads on the EPYC Embedded 7402.
Who each one is for
Buy the EPYC 7543 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. The EPYC Embedded 7402 is the one to take 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.
Where the two are identical
The common ground is wider than the gap: pcie lanes, base clock and socket are identical here.

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 7402 if you already have it on hand or find it at a lower price.
