AMD EPYC 7773X vs AMD EPYC Embedded 7301: Comparison
What is the difference between EPYC 7773X and EPYC Embedded 7301?
Start with l3 cache, because it is the widest measured gap between them: EPYC 7773X 768 MB against EPYC Embedded 7301 64 MB, 92% in favour of EPYC 7773X. They differ on boost clock too, Up to 3.5 GHz on the EPYC 7773X versus 2.9 GHz on the EPYC Embedded 7301. Tdp is not the same on both, 280 W on the EPYC 7773X versus 155 W on the EPYC Embedded 7301. There is a split on core count as well, 64 cores on the EPYC 7773X versus 16 cores on the EPYC Embedded 7301. Thread count is not the same on both, 128 threads on the EPYC 7773X versus 32 threads on the EPYC Embedded 7301.
Which should you buy, EPYC 7773X or EPYC Embedded 7301?
Buy the EPYC 7773X for datacenter and cloud compute and virtualization-dense server workloads, though it is not the pick for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs. The EPYC Embedded 7301 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.
What EPYC 7773X and EPYC Embedded 7301 have in common
Everything else lines up. Pcie lanes, base clock and socket read the same on both, so those are not worth weighing.
