AMD EPYC 7663P Review
AMD EPYC 7663P server processor, 56C/112T 2 GHz base clock, boosting up to 3.5 ghz, 240W TDP, SP3 platform.
The AMD EPYC 7663P is an AMD EPYC server processor in the EPYC 7003 Series lineup, offering 56C/112T running at 2 GHz base clock, boosting up to 3.5 ghz with 256 MB of L3 cache, within a 240W power envelope on AMD's SP3 platform in 1P configurations.
Performance and Architecture
With 56C/112T, the AMD EPYC 7663P runs at 2 GHz base clock, boosting up to 3.5 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 7663P is built for AMD's SP3 platform, supporting 1P socket configurations. It supports DDR4 memory across 8 channels (Up to 3200 MT/s). I/O runs over PCIe 4.0 x128.
Comparison to Alternatives
Within the EPYC 7003 Series lineup in this catalog, the AMD EPYC 7663P 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.
