AMD EPYC 9734 vs AMD EPYC Embedded 9655: Comparison
EPYC 9734 vs EPYC Embedded 9655 l3 cache compared
The gap that matters here is l3 cache: EPYC 9734 256 MB against EPYC Embedded 9655 384 MB, which puts EPYC Embedded 9655 33% ahead. Boost clock is not the same on both, 3.0 GHz on the EPYC 9734 versus 4.5 GHz on the EPYC Embedded 9655. They differ on tdp too, 320 W on the EPYC 9734 versus 400 W on the EPYC Embedded 9655. There is a split on core count as well, 112 cores on the EPYC 9734 versus 96 cores on the EPYC Embedded 9655. Thread count is not the same on both, 224 threads on the EPYC 9734 versus 192 threads on the EPYC Embedded 9655. They differ on core architecture too, Zen 4c "Bergamo" on the EPYC 9734 versus Zen 5 on the EPYC Embedded 9655. There is a split on base clock as well, 2.2 GHz on the EPYC 9734 versus 2.6 GHz on the EPYC Embedded 9655. Multi-socket support is not the same on both, 1P/2P on the EPYC 9734 versus Dual Socket on the EPYC Embedded 9655.
Which should you buy, EPYC 9734 or EPYC Embedded 9655?
The EPYC 9734 is the one to take for dense virtualization hosts and cloud-native container platforms, though it is the wrong buy for small server deployments and per-core licensed software. The EPYC Embedded 9655 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 9734 (9/10): the EPYC 9734 offers very high core density for dense virtualization hosts without going all the way to AMD's 128-core flagship.
Where the two are identical
The common ground is wider than the gap: memory channels, socket and ecc support are identical here.
