AMD EPYC 9745 vs AMD EPYC Embedded 9755: Comparison
What is the difference between EPYC 9745 and EPYC Embedded 9755?
Start with l3 cache, because it is the widest measured gap between them: EPYC 9745 384 MB against EPYC Embedded 9755 512 MB, 25% in favour of EPYC Embedded 9755. There is a split on boost clock as well, 4.0 GHz on the EPYC 9745 versus 4.1 GHz on the EPYC Embedded 9755. They differ on tdp too, 400 W on the EPYC 9745 versus 500 W on the EPYC Embedded 9755. Core architecture is not the same on both, Zen 5c "Turin Dense" on the EPYC 9745 versus Zen 5 on the EPYC Embedded 9755. They differ on base clock too, 2.4 GHz on the EPYC 9745 versus 2.7 GHz on the EPYC Embedded 9755. Multi-socket support is not the same on both, 1P/2P on the EPYC 9745 versus Dual Socket on the EPYC Embedded 9755.
Who each one is for
The EPYC 9745 suits hyperscale cloud and VM hosting and container-dense Kubernetes nodes, though it is the wrong buy for small server deployments and per-core licensed software. The EPYC Embedded 9755 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 9745 (9.1/10): the EPYC 9745 delivers 128-core density at a more power-conscious 400W, making it the efficiency-minded pick for hyperscale deployments.
What EPYC 9745 and EPYC Embedded 9755 have in common
Everything else lines up. Memory channels, core count, thread count, socket and ecc support read the same on both, so those are not worth weighing.
