AMD EPYC 9334 vs AMD EPYC Embedded 9745: Comparison
EPYC 9334 vs EPYC Embedded 9745: the l3 cache difference
On l3 cache the spread is 50%, EPYC 9334 128 MB against EPYC Embedded 9745 256 MB, so EPYC Embedded 9745 takes it. Boost clock is not the same on both, 3.9 GHz on the EPYC 9334 versus 3.7 GHz on the EPYC Embedded 9745. Tdp is not the same on both, 210 W on the EPYC 9334 versus 400 W on the EPYC Embedded 9745. They differ on core count too, 32 cores on the EPYC 9334 versus 128 cores on the EPYC Embedded 9745. They differ on thread count too, 64 threads on the EPYC 9334 versus 256 threads on the EPYC Embedded 9745. There is a split on core architecture as well, Zen 4 "Genoa" on the EPYC 9334 versus Zen 5c on the EPYC Embedded 9745. There is a split on base clock as well, 2.7 GHz on the EPYC 9334 versus 2.4 GHz on the EPYC Embedded 9745. Multi-socket support is not the same on both, 1P/2P on the EPYC 9334 versus Dual Socket on the EPYC Embedded 9745.
Who each one is for
Buy the EPYC 9334 for small to mid-size server deployments and edge infrastructure, though it is not built for maximum core density workloads and large-scale hyperscale deployments. The EPYC Embedded 9745 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. Our rating of the EPYC 9334 (8.4/10): the EPYC 9334 is a sensible entry point into the EPYC platform for smaller deployments that still want server-grade memory bandwidth and reliability.
Where the two are identical
The common ground is wider than the gap: memory channels, socket and ecc support are identical here.
