AMD EPYC 9655 vs AMD EPYC Embedded 9745: Comparison
EPYC 9655 vs EPYC Embedded 9745 l3 cache compared
The gap that matters here is l3 cache: EPYC 9655 384 MB against EPYC Embedded 9745 256 MB, which puts EPYC 9655 33% ahead. They differ on boost clock too, 4.4 GHz on the EPYC 9655 versus 3.7 GHz on the EPYC Embedded 9745. There is a split on tdp as well, 360 W on the EPYC 9655 versus 400 W on the EPYC Embedded 9745. Core count is not the same on both, 96 cores on the EPYC 9655 versus 128 cores on the EPYC Embedded 9745. They differ on thread count too, 192 threads on the EPYC 9655 versus 256 threads on the EPYC Embedded 9745. There is a split on core architecture as well, Zen 5 "Turin" on the EPYC 9655 versus Zen 5c on the EPYC Embedded 9745. Base clock is not the same on both, 2.9 GHz on the EPYC 9655 versus 2.4 GHz on the EPYC Embedded 9745. They differ on multi-socket support too, 1P/2P on the EPYC 9655 versus Dual Socket on the EPYC Embedded 9745.
EPYC 9655 vs EPYC Embedded 9745: which one fits your build
The EPYC 9655 is the one to take for mixed virtualization and database workloads and high-throughput web tiers, though it is the wrong buy for maximum absolute core density needs and cost-sensitive small deployments. The EPYC Embedded 9745 suits 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 9655 (8.9/10): the EPYC 9655 is one of the best-balanced high-core-count EPYC SKUs, combining genuine density with clocks that don't lag far behind AMD's frequency-optimized parts.
Where the two are identical
Everything else lines up. Memory channels, socket and ecc support read the same on both, so those are not worth weighing.
