AMD EPYC 7763 vs AMD EPYC Embedded 7551: Comparison
EPYC 7763 vs EPYC Embedded 7551 l3 cache compared
L3 cache is where these two genuinely part company, EPYC 7763 256 MB against EPYC Embedded 7551 64 MB, a 75% lead for EPYC 7763. They differ on boost clock too, Up to 3.5 GHz on the EPYC 7763 versus 3 GHz on the EPYC Embedded 7551. They differ on tdp too, 280 W on the EPYC 7763 versus 180 W on the EPYC Embedded 7551. Core count is not the same on both, 64 cores on the EPYC 7763 versus 32 cores on the EPYC Embedded 7551. They differ on thread count too, 128 threads on the EPYC 7763 versus 64 threads on the EPYC Embedded 7551. Base clock is not the same on both, 2.45 GHz on the EPYC 7763 versus 2 GHz on the EPYC Embedded 7551.
Which should you buy, EPYC 7763 or EPYC Embedded 7551?
The EPYC 7763 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 7551 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 7763 and EPYC Embedded 7551 have in common
Everything else lines up. Pcie lanes and socket read the same on both, so those are not worth weighing.
