AMD EPYC 9115 Review
AMD EPYC 9115 16-core 32-thread SP5 server processor, 2.6GHz base / 4.1GHz boost, 125W TDP, 128MB L3 cache, Zen 5 "Turin"
The EPYC 9115 is an entry-to-mid EPYC processor aimed at smaller server deployments, edge infrastructure, or power-constrained racks where core count is deliberately kept modest. Built on Zen 5 "Turin" and rated for just 125W, it pairs 16 cores and 32 threads with a 2.6GHz base clock that boosts up to 4.1GHz, backed by 128MB of L3 cache on AMD's SP5 server platform.
Core Count and Workload Fit
With 16 cores and 32 threads, the EPYC 9115 is built for data center workloads that don't need extreme core density: small virtualization hosts, edge compute, and moderate web-tier fleets. The wide gap between its 2.6GHz base and 4.1GHz boost means single-threaded bursts perform well even though sustained all-core clocks are modest. The 128MB L3 cache is generous relative to its core count.
Platform, Memory, and Cooling
The EPYC 9115 runs on AMD's SP5 platform with 12-channel DDR5 memory support and up to 128 PCIe 5.0 lanes per socket, giving it enormous memory bandwidth relative to its modest core count. It supports both single-socket (1P) and dual-socket (2P) server designs. At just 125W, it is one of the easiest current EPYC SKUs to cool, fitting tighter edge chassis than AMD's high-core-count parts.
Comparison to Alternatives
Compared to the higher core-count EPYC 9354 and EPYC 9454 in this catalog, the EPYC 9115 is the more affordable and far lower-power entry point into the current EPYC generation, suited to smaller or power-constrained deployments. Against a Ryzen 9 desktop chip, it adds ECC memory, 12-channel bandwidth, and genuine server-grade reliability features that a desktop platform simply doesn't offer. It undercuts equivalent-tier Intel Xeon Scalable entry parts in this catalog on memory channel count and power draw.

Expert rating8.5 / 10
The EPYC 9115 is a well-balanced low-power entry point that still gets the full EPYC platform's memory bandwidth advantage.
Best for
- Power-constrained edge deployments
- Small to mid-size virtualization hosts
- Cost-conscious server refreshes
Not for
- Maximum core density workloads
- Large-scale hyperscale deployments
- Cache-bound technical computing
