AMD EPYC 7643 vs AMD EPYC Embedded 7302P: Comparison
What is the difference between EPYC 7643 and EPYC Embedded 7302P?
The gap that matters here is l3 cache: EPYC 7643 256 MB against EPYC Embedded 7302P 128 MB, which puts EPYC 7643 50% ahead. There is a split on boost clock as well, Up to 3.6 GHz on the EPYC 7643 versus 3.3 GHz on the EPYC Embedded 7302P. Tdp is not the same on both, 225 W on the EPYC 7643 versus 155 W on the EPYC Embedded 7302P. They differ on core count too, 48 cores on the EPYC 7643 versus 16 cores on the EPYC Embedded 7302P. Thread count is not the same on both, 96 threads on the EPYC 7643 versus 32 threads on the EPYC Embedded 7302P. They differ on base clock too, 2.3 GHz on the EPYC 7643 versus 3 GHz on the EPYC Embedded 7302P.
Which should you buy, EPYC 7643 or EPYC Embedded 7302P?
Buy the EPYC 7643 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. The EPYC Embedded 7302P 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.
Where the two are identical
Where they agree, they agree completely, pcie lanes and socket included, so the decision does not turn on any of those.

Which one should you pick?
Choose 7643 if you want the higher L3 cache (256 MB vs 128 MB) and the higher PCIe lanes (128 lanes vs 128 lanes).
Choose 7302P if you already have it on hand or find it at a lower price.
