AMD EPYC 9645 vs AMD EPYC Embedded 9335: Comparison
EPYC 9645 vs EPYC Embedded 9335: the l3 cache difference
On l3 cache the spread is 67%, EPYC 9645 384 MB against EPYC Embedded 9335 128 MB, so EPYC 9645 takes it. Boost clock is not the same on both, 4.0 GHz on the EPYC 9645 versus 4.4 GHz on the EPYC Embedded 9335. Tdp is not the same on both, 370 W on the EPYC 9645 versus 210 W on the EPYC Embedded 9335. They differ on core count too, 96 cores on the EPYC 9645 versus 32 cores on the EPYC Embedded 9335. They differ on thread count too, 192 threads on the EPYC 9645 versus 64 threads on the EPYC Embedded 9335. There is a split on core architecture as well, Zen 5c "Turin Dense" on the EPYC 9645 versus Zen 5 on the EPYC Embedded 9335. There is a split on base clock as well, 2.3 GHz on the EPYC 9645 versus 3 GHz on the EPYC Embedded 9335.
Who each one is for
Buy the EPYC 9645 for cloud tenancy and container hosting and dense virtualization at moderate power, though it is the wrong buy for single-thread-sensitive workloads and maximum absolute core count needs. The EPYC Embedded 9335 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. Our rating of the EPYC 9645 (8.7/10): the EPYC 9645 is a solid mid-tier dense-core option for cloud hosts that want more cores per socket without jumping to AMD's largest dense SKUs.
Where the two are identical
Everything else lines up. Socket and multi-socket support read the same on both, so those are not worth weighing.
