AMD EPYC 9456P Review
AMD EPYC 9456P server processor, 48C/96T 3.2 GHz base clock, boosting up to 3.7 ghz, 265W (CPU Power Range: 155W-300W) TDP, SP8 platform.
The AMD EPYC 9456P is an AMD EPYC server processor in the EPYC 9006 Series lineup, offering 48C/96T running at 3.2 GHz base clock, boosting up to 3.7 ghz with 256 MB of L3 cache, within a 265W (CPU Power Range: 155W-300W) power envelope on AMD's SP8 platform in 1P configurations.
Performance and Architecture
With 48C/96T, the AMD EPYC 9456P runs at 3.2 GHz base clock, boosting up to 3.7 ghz. It carries 256 MB of L3 cache to keep large working sets close to the cores. As part of AMD's EPYC server lineup, it targets dense multi-socket compute, virtualization, and datacenter workloads.
Platform and Memory
The AMD EPYC 9456P is built for AMD's SP8 platform, supporting 1P socket configurations. It supports DDR5 RDIMM | MRDIMM memory across 8 channels (Up to 8000 MT/s / Up to 12800 MT/s). I/O runs over PCIe 6.0 x128.
Comparison to Alternatives
Within the EPYC 9006 Series lineup in this catalog, the AMD EPYC 9456P is positioned by its core count, clock speed, and TDP relative to other EPYC parts in the same generation. Buyers should weigh core density against per-core clock speed depending on whether the target workload favors many parallel threads or fewer, faster ones.
