AMD EPYC 9825 vs AMD EPYC Embedded 9555P: Comparison
What is the difference between EPYC 9825 and EPYC Embedded 9555P?
The gap that matters here is l3 cache: EPYC 9825 384 MB against EPYC Embedded 9555P 256 MB, which puts EPYC 9825 33% ahead. Boost clock is not the same on both, 3.8 GHz on the EPYC 9825 versus 4.4 GHz on the EPYC Embedded 9555P. They differ on tdp too, 400 W on the EPYC 9825 versus 360 W on the EPYC Embedded 9555P. There is a split on core count as well, 128 cores on the EPYC 9825 versus 64 cores on the EPYC Embedded 9555P. Thread count is not the same on both, 256 threads on the EPYC 9825 versus 128 threads on the EPYC Embedded 9555P. They differ on core architecture too, Zen 5c "Turin Dense" on the EPYC 9825 versus Zen 5 on the EPYC Embedded 9555P. There is a split on base clock as well, 2.5 GHz on the EPYC 9825 versus 3.2 GHz on the EPYC Embedded 9555P. Multi-socket support is not the same on both, 1P/2P on the EPYC 9825 versus Single Socket Only on the EPYC Embedded 9555P.
Who each one is for
The EPYC 9825 suits hyperscale cloud provider fleets and consistent-throughput VM hosting at scale, though it is not the pick for general enterprise deployments and peak single-thread workloads. Buy the EPYC Embedded 9555P 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 9825 (9/10): the EPYC 9825 is a specialized, cloud-provider-oriented 128-core SKU best reserved for hyperscale operators rather than general enterprise buyers.
Where the two are identical
Where they agree, they agree completely, memory channels, socket and ecc support included, so the decision does not turn on any of those.
