There is a split on boost clock as well, 4.5 GHz on the EPYC 9755 versus 4.3 GHz on the EPYC Embedded 9255. There is a split on tdp as well, 500 W on the EPYC 9755 versus 200 W on the EPYC Embedded 9255. They differ on core count too, 128 cores on the EPYC 9755 versus 24 cores on the EPYC Embedded 9255. There is a split on thread count as well, 256 threads on the EPYC 9755 versus 48 threads on the EPYC Embedded 9255. They differ on core architecture too, Zen 5 "Turin" on the EPYC 9755 versus Zen 5 on the EPYC Embedded 9255. They differ on base clock too, 2.7 GHz on the EPYC 9755 versus 3.25 GHz on the EPYC Embedded 9255. Multi-socket support is not the same on both, Dual Socket on the EPYC 9755 versus 1P/2P on the EPYC Embedded 9255.
EPYC 9755 vs EPYC Embedded 9255: which one fits your build
Buy the EPYC 9755 for large-scale enterprise databases and HPC and technical computing at scale, though it is not built for power-constrained deployments and small server rooms. The EPYC Embedded 9255 suits 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. Our rating of the EPYC 9755 (9.4/10): the EPYC 9755 is AMD's most powerful standard-core EPYC SKU, pairing 128 cores with clocks that make few compromises for organizations that can afford the 500W power budget.
What EPYC 9755 and EPYC Embedded 9255 have in common
Where they agree, they agree completely, socket included, so the decision does not turn on any of those.
