AMD EPYC Embedded 9255 vs AMD EPYC Embedded 9354P: Comparison
What is the difference between EPYC Embedded 9255 and EPYC Embedded 9354P?
Start with l3 cache, because it is the widest measured gap between them: EPYC Embedded 9255 128 MB against EPYC Embedded 9354P 256 MB, 50% in favour of EPYC Embedded 9354P. There is a split on boost clock as well, 4.3 GHz on the EPYC Embedded 9255 versus 3.8 GHz on the EPYC Embedded 9354P. They differ on tdp too, 200 W on the EPYC Embedded 9255 versus 280 W on the EPYC Embedded 9354P. Core count is not the same on both, 24 cores on the EPYC Embedded 9255 versus 32 cores on the EPYC Embedded 9354P. They differ on thread count too, 48 threads on the EPYC Embedded 9255 versus 64 threads on the EPYC Embedded 9354P. Core architecture is not the same on both, Zen 5 on the EPYC Embedded 9255 versus Zen 4 on the EPYC Embedded 9354P. There is a split on multi-socket support as well, 1P/2P on the EPYC Embedded 9255 versus 1P on the EPYC Embedded 9354P.
Who each one is for
The EPYC Embedded 9255 is the one to take for industrial and embedded system designs and long-lifecycle networking and edge-compute deployments, though it is not built for consumer desktop or gaming builds and DIY PC upgrades. Buy the EPYC Embedded 9354P 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 Embedded 9255 and EPYC Embedded 9354P have in common
Everything else lines up. Base clock and socket read the same on both, so those are not worth weighing.
