AMD EPYC 7601 vs AMD EPYC 7662: Comparison
EPYC 7601 vs EPYC 7662 l3 cache compared
The gap that matters here is l3 cache: EPYC 7601 64 MB against EPYC 7662 256 MB, which puts EPYC 7662 75% ahead. The benchmark result agrees. SPECrate® 2017 Integer (base), 1-chip puts EPYC 7662 57% ahead, 356 against 153. They differ on tdp too, 180 W on the EPYC 7601 versus 225 W on the EPYC 7662. L2 cache runs the same way, 16 MB on the EPYC 7601 versus 32 MB on the EPYC 7662, another win for EPYC 7662. They differ on product family too, Zen, EPYC 7001 "Naples" on the EPYC 7601 versus Zen 2, EPYC 7002 "Rome" on the EPYC 7662. There is a split on core count as well, 32 cores on the EPYC 7601 versus 64 cores on the EPYC 7662. Thread count is not the same on both, 64 threads on the EPYC 7601 versus 128 threads on the EPYC 7662. They differ on base clock too, 2.2 GHz on the EPYC 7601 versus 2.0 GHz on the EPYC 7662.
EPYC 7601 vs EPYC 7662: which one fits your build
Take the EPYC 7601 for data center deployments specifically wanting AMD's original first-generation EPYC flagship at the highest available core count. It is the wrong buy for buyers with access to later Rome-generation EPYC chips, those offer meaningfully better per-core performance. Take the EPYC 7662 for data center and server deployments needing genuine 64-core, 128-thread aggregate throughput. Avoid it for any consumer, gaming, or workstation desktop use, this is purpose-built server hardware requiring specialized infrastructure.
Frequently asked questions
Do the EPYC 7601 and EPYC 7662 differ on boost clock?
Yes. Boost Clock reads 3.2 GHz on the EPYC 7601 versus 3.3 GHz on the EPYC 7662.
Is the Socket the same on the EPYC 7601 and EPYC 7662?
It is. Both are listed at LGA 4094, so it is not a reason to pick one over the other.
