AMD EPYC 9455 vs AMD EPYC Embedded 9755: Comparison
EPYC 9455 vs EPYC Embedded 9755 l3 cache compared
Start with l3 cache, because it is the widest measured gap between them: EPYC 9455 256 MB against EPYC Embedded 9755 512 MB, 50% in favour of EPYC Embedded 9755. There is a split on boost clock as well, 4.35 GHz on the EPYC 9455 versus 4.1 GHz on the EPYC Embedded 9755. They differ on tdp too, 280 W on the EPYC 9455 versus 500 W on the EPYC Embedded 9755. Core count is not the same on both, 48 cores on the EPYC 9455 versus 128 cores on the EPYC Embedded 9755. They differ on thread count too, 96 threads on the EPYC 9455 versus 256 threads on the EPYC Embedded 9755. Core architecture is not the same on both, Zen 5 "Turin" on the EPYC 9455 versus Zen 5 on the EPYC Embedded 9755. There is a split on base clock as well, 3.15 GHz on the EPYC 9455 versus 2.7 GHz on the EPYC Embedded 9755. They differ on multi-socket support too, 1P/2P on the EPYC 9455 versus Dual Socket on the EPYC Embedded 9755.
Which should you buy, EPYC 9455 or EPYC Embedded 9755?
The EPYC 9455 is the one to take for virtualization hosts and database servers, though it is not built for cost-sensitive small deployments and single-threaded legacy applications. Buy the EPYC Embedded 9755 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. Our rating of the EPYC 9455 (8.8/10): the EPYC 9455 is a well-rounded high-core-count EPYC SKU that balances density, clocks, and power draw for mainstream data center use.
What EPYC 9455 and EPYC Embedded 9755 have in common
The common ground is wider than the gap: memory channels, socket and ecc support are identical here.
