AMD EPYC 7643P vs AMD EPYC Embedded 7501: Comparison
EPYC 7643P vs EPYC Embedded 7501: the l3 cache difference
L3 cache is where these two genuinely part company, EPYC 7643P 256 MB against EPYC Embedded 7501 64 MB, a 75% lead for EPYC 7643P. They differ on boost clock too, Up to 3.6 GHz on the EPYC 7643P versus 3 GHz on the EPYC Embedded 7501. They differ on tdp too, 225 W on the EPYC 7643P versus 155 W on the EPYC Embedded 7501. Core count is not the same on both, 48 cores on the EPYC 7643P versus 32 cores on the EPYC Embedded 7501. Thread count is not the same on both, 96 threads on the EPYC 7643P versus 64 threads on the EPYC Embedded 7501. There is a split on base clock as well, 2.3 GHz on the EPYC 7643P versus 2 GHz on the EPYC Embedded 7501.
Which should you buy, EPYC 7643P or EPYC Embedded 7501?
The EPYC 7643P 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 7501 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 7643P and EPYC Embedded 7501 have in common
The common ground is wider than the gap: pcie lanes and socket are identical here.
