AMD EPYC 9256 vs AMD EPYC 9526: Comparison
EPYC 9256 vs EPYC 9526 l3 cache compared
L3 cache is where these two genuinely part company, EPYC 9256 96 MB against EPYC 9526 256 MB, a 63% lead for EPYC 9526. They differ on boost clock too, 4.5 GHz on the EPYC 9256 versus 3.7 GHz on the EPYC 9526. They differ on tdp too, 190 W on the EPYC 9256 versus 220 W on the EPYC 9526. Core count is not the same on both, 24 cores on the EPYC 9256 versus 64 cores on the EPYC 9526. Thread count is not the same on both, 48 threads on the EPYC 9256 versus 128 threads on the EPYC 9526. There is a split on base clock as well, 2.85 GHz on the EPYC 9256 versus 2.75 GHz on the EPYC 9526.
Which should you buy, EPYC 9256 or EPYC 9526?
The EPYC 9256 suits datacenter and cloud compute and virtualization-dense server workloads, though it is not built for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs. The EPYC 9526 is the one to take for datacenter and cloud compute and virtualization-dense server workloads, though it is the wrong buy for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs.
What EPYC 9256 and EPYC 9526 have in common
Where they agree, they agree completely, configurable tdp max, memory channels, pcie lanes, cpu socket and product family included, so the decision does not turn on any of those. They match on 11 further specifications as well.
Frequently asked questions
Is the Segment the same on the EPYC 9256 and EPYC 9526?
It is. Both are listed at Data Center, so it is not a reason to pick one over the other.
