AMD EPYC 7551P vs AMD EPYC Embedded 7552: Comparison
EPYC 7551P vs EPYC Embedded 7552: the l3 cache difference
Start with l3 cache, because it is the widest measured gap between them: EPYC 7551P 64 MB against EPYC Embedded 7552 192 MB, 67% in favour of EPYC Embedded 7552. Boost clock is not the same on both, Up to 3 GHz on the EPYC 7551P versus 3.3 GHz on the EPYC Embedded 7552. There is a split on tdp as well, 180 W on the EPYC 7551P versus 200 W on the EPYC Embedded 7552. They differ on core count too, 32 cores on the EPYC 7551P versus 48 cores on the EPYC Embedded 7552. Thread count is not the same on both, 64 threads on the EPYC 7551P versus 96 threads on the EPYC Embedded 7552. There is a split on base clock as well, 2 GHz on the EPYC 7551P versus 2.2 GHz on the EPYC Embedded 7552.
EPYC 7551P vs EPYC Embedded 7552: which one fits your build
The EPYC 7551P 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 7552 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 7551P and EPYC Embedded 7552 have in common
Where they agree, they agree completely, pcie lanes and socket included, so the decision does not turn on any of those.
