AMD EPYC 9556 vs AMD EPYC 9G76: Comparison
What is the difference between EPYC 9556 and EPYC 9G76?
The first real difference is boost clock: EPYC 9556 4.3 GHz against EPYC 9G76 4.8 GHz. Tdp is not the same on both, 300 W on the EPYC 9556 versus 500 W on the EPYC 9G76. Configurable tdp max is not the same on both, 300 W on the EPYC 9556 versus 500 W on the EPYC 9G76. There is a split on core count as well, 64 cores on the EPYC 9556 versus 96 cores on the EPYC 9G76. Thread count is not the same on both, 128 threads on the EPYC 9556 versus 192 threads on the EPYC 9G76. There is a split on base clock as well, 2.75 GHz on the EPYC 9556 versus 3.4 GHz on the EPYC 9G76. There is a split on launch price as well, $8,008 on the EPYC 9556 versus $11,622 on the EPYC 9G76.
Who each one is for
The EPYC 9556 is the one to take 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. Buy the EPYC 9G76 for 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.
What EPYC 9556 and EPYC 9G76 have in common
Where they agree, they agree completely, l3 cache, 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 9556 and EPYC 9G76?
It is. Both are listed at Data Center, so it is not a reason to pick one over the other.
