AMD EPYC 7H12 vs AMD EPYC Embedded 7542: Comparison
EPYC 7H12 vs EPYC Embedded 7542 l3 cache compared
The gap that matters here is l3 cache: EPYC 7H12 256 MB against EPYC Embedded 7542 128 MB, which puts EPYC 7H12 50% ahead. There is a split on boost clock as well, Up to 3.3 GHz on the EPYC 7H12 versus 3.4 GHz on the EPYC Embedded 7542. Tdp is not the same on both, 280 W on the EPYC 7H12 versus 225 W on the EPYC Embedded 7542. They differ on core count too, 64 cores on the EPYC 7H12 versus 32 cores on the EPYC Embedded 7542. There is a split on thread count as well, 128 threads on the EPYC 7H12 versus 64 threads on the EPYC Embedded 7542. Base clock is not the same on both, 2.6 GHz on the EPYC 7H12 versus 2.9 GHz on the EPYC Embedded 7542.
EPYC 7H12 vs EPYC Embedded 7542: which one fits your build
Buy the EPYC 7H12 for datacenter and cloud compute and virtualization-dense server workloads, though it is not the pick for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs. The EPYC Embedded 7542 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.
Where the two are identical
The common ground is wider than the gap: pcie lanes and socket are identical here.

Which one should you pick?
Choose 7H12 if you want the higher L3 cache (256 MB vs 128 MB) and the higher PCIe lanes (128 lanes vs 128 lanes).
Choose 7542 if you already have it on hand or find it at a lower price.
