AMD EPYC 7H12 vs AMD EPYC Embedded 7402: Comparison
EPYC 7H12 vs EPYC Embedded 7402: the l3 cache difference
Start with l3 cache, because it is the widest measured gap between them: EPYC 7H12 256 MB against EPYC Embedded 7402 128 MB, 50% in favour of EPYC 7H12. They differ on boost clock too, Up to 3.3 GHz on the EPYC 7H12 versus 3.35 GHz on the EPYC Embedded 7402. Tdp is not the same on both, 280 W on the EPYC 7H12 versus 180 W on the EPYC Embedded 7402. There is a split on core count as well, 64 cores on the EPYC 7H12 versus 24 cores on the EPYC Embedded 7402. They differ on thread count too, 128 threads on the EPYC 7H12 versus 48 threads on the EPYC Embedded 7402. Base clock is not the same on both, 2.6 GHz on the EPYC 7H12 versus 2.8 GHz on the EPYC Embedded 7402.
EPYC 7H12 vs EPYC Embedded 7402: which one fits your build
The EPYC 7H12 is the one to take for 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. Buy the EPYC Embedded 7402 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 7H12 and EPYC Embedded 7402 have in common
Everything else lines up. Pcie lanes and socket read the same on both, so those are not worth weighing.

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