AMD EPYC 7542 vs AMD EPYC Embedded 735P: Comparison
What is the difference between EPYC 7542 and EPYC Embedded 735P?
Start with l3 cache, because it is the widest measured gap between them: EPYC 7542 128 MB against EPYC Embedded 735P 64 MB, 50% in favour of EPYC 7542. Boost clock is not the same on both, Up to 3.4 GHz on the EPYC 7542 versus 2.9 GHz on the EPYC Embedded 735P. There is a split on tdp as well, 225 W on the EPYC 7542 versus 155 W on the EPYC Embedded 735P. They differ on core count too, 32 cores on the EPYC 7542 versus 16 cores on the EPYC Embedded 735P. There is a split on thread count as well, 64 threads on the EPYC 7542 versus 32 threads on the EPYC Embedded 735P. They differ on base clock too, 2.9 GHz on the EPYC 7542 versus 2.4 GHz on the EPYC Embedded 735P.
Who each one is for
The EPYC 7542 suits 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 735P 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.
What EPYC 7542 and EPYC Embedded 735P 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 735P if you already have it on hand or find it at a lower price.
