AMD EPYC 7663 vs AMD EPYC Embedded 7501: Comparison
What is the difference between EPYC 7663 and EPYC Embedded 7501?
Start with l3 cache, because it is the widest measured gap between them: EPYC 7663 256 MB against EPYC Embedded 7501 64 MB, 75% in favour of EPYC 7663. Boost clock is not the same on both, Up to 3.5 GHz on the EPYC 7663 versus 3 GHz on the EPYC Embedded 7501. There is a split on tdp as well, 240 W on the EPYC 7663 versus 155 W on the EPYC Embedded 7501. They differ on core count too, 56 cores on the EPYC 7663 versus 32 cores on the EPYC Embedded 7501. Thread count is not the same on both, 112 threads on the EPYC 7663 versus 64 threads on the EPYC Embedded 7501.
EPYC 7663 vs EPYC Embedded 7501: which one fits your build
The EPYC 7663 suits 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 7501 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.
What EPYC 7663 and EPYC Embedded 7501 have in common
The common ground is wider than the gap: pcie lanes, base clock and socket are identical here.

Which one should you pick?
Choose 7663 if you want the higher L3 cache (256 MB vs 64 MB) and the higher PCIe lanes (128 lanes vs 128 lanes).
Choose 7501 if you already have it on hand or find it at a lower price.
