AMD EPYC 7401P vs AMD EPYC Embedded 7551: Comparison
What is the difference between EPYC 7401P and EPYC Embedded 7551?
They are built to different briefs, and boost clock shows it, EPYC 7401P Up to 3 GHz against EPYC Embedded 7551 3 GHz. They differ on tdp too, 155W / 170W on the EPYC 7401P versus 180 W on the EPYC Embedded 7551. There is a split on core count as well, 24 cores on the EPYC 7401P versus 32 cores on the EPYC Embedded 7551. Thread count is not the same on both, 48 threads on the EPYC 7401P versus 64 threads on the EPYC Embedded 7551.
EPYC 7401P vs EPYC Embedded 7551: which one fits your build
The EPYC 7401P 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. Buy the EPYC Embedded 7551 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.
Where the two are identical
Everything else lines up. L3 cache, pcie lanes, base clock and socket read the same on both, so those are not worth weighing.
