AMD EPYC 7542 vs AMD EPYC Embedded 740P: Comparison
EPYC 7542 vs EPYC Embedded 740P: the l3 cache difference
Start with l3 cache, because it is the widest measured gap between them: EPYC 7542 128 MB against EPYC Embedded 740P 64 MB, 50% in favour of EPYC 7542. They differ on boost clock too, Up to 3.4 GHz on the EPYC 7542 versus 3 GHz on the EPYC Embedded 740P. Tdp is not the same on both, 225 W on the EPYC 7542 versus 155 W on the EPYC Embedded 740P. There is a split on core count as well, 32 cores on the EPYC 7542 versus 24 cores on the EPYC Embedded 740P. They differ on thread count too, 64 threads on the EPYC 7542 versus 48 threads on the EPYC Embedded 740P. Base clock is not the same on both, 2.9 GHz on the EPYC 7542 versus 2 GHz on the EPYC Embedded 740P.
EPYC 7542 vs EPYC Embedded 740P: which one fits your build
The EPYC 7542 is the one to take 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. Buy the EPYC Embedded 740P 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.
What EPYC 7542 and EPYC Embedded 740P 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 7542 if you want the higher L3 cache (128 MB vs 64 MB) and the higher PCIe lanes (128 lanes vs 128 lanes).
Choose 740P if you already have it on hand or find it at a lower price.
