AMD EPYC 7303 vs AMD EPYC Embedded 7551: Comparison
What is the difference between EPYC 7303 and EPYC Embedded 7551?
The first real difference is boost clock: EPYC 7303 Up to 3.4 GHz against EPYC Embedded 7551 3 GHz. They differ on tdp too, 130 W on the EPYC 7303 versus 180 W on the EPYC Embedded 7551. Core count is not the same on both, 16 cores on the EPYC 7303 versus 32 cores on the EPYC Embedded 7551. There is a split on thread count as well, 32 threads on the EPYC 7303 versus 64 threads on the EPYC Embedded 7551. Base clock is not the same on both, 2.4 GHz on the EPYC 7303 versus 2 GHz on the EPYC Embedded 7551.
EPYC 7303 vs EPYC Embedded 7551: which one fits your build
The EPYC 7303 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 7551 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 7303 and EPYC Embedded 7551 have in common
Where they agree, they agree completely, l3 cache, pcie lanes and socket included, so the decision does not turn on any of those.
