AMD EPYC 7551P Review
AMD EPYC 7551P server processor, 32C/64T 2 GHz base clock, boosting up to 3 ghz, 180W TDP, SP3 platform.
The AMD EPYC 7551P is an AMD EPYC server processor in the EPYC 7001 Series lineup, offering 32C/64T running at 2 GHz base clock, boosting up to 3 ghz with 64 MB of L3 cache, within a 180W power envelope on AMD's SP3 platform in 1P configurations.
Performance and Architecture
With 32C/64T, the AMD EPYC 7551P runs at 2 GHz base clock, boosting up to 3 ghz. It carries 64 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 7551P is built for AMD's SP3 platform, supporting 1P socket configurations. It supports DDR4 memory across 8 channels (Up to 2666 MT/s). I/O runs over PCIe 3.0 x128.
Comparison to Alternatives
Within the EPYC 7001 Series lineup in this catalog, the AMD EPYC 7551P 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.
