AMD EPYC 4545P Review
AMD EPYC 4545P server processor, 16C/32T 3 GHz base clock, boosting up to 5.4 ghz, 65W TDP, AM5 platform.
The AMD EPYC 4545P is an AMD EPYC server processor in the EPYC 4005 Series lineup, offering 16C/32T running at 3 GHz base clock, boosting up to 5.4 ghz with 64 MB of L3 cache, within a 65W power envelope on AMD's AM5 platform in 1P configurations.
Performance and Architecture
With 16C/32T, the AMD EPYC 4545P runs at 3 GHz base clock, boosting up to 5.4 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 4545P is built for AMD's AM5 platform, supporting 1P socket configurations. It supports DDR5 memory across 2 channels (Up to 5600 MT/s). I/O runs over PCIe 5.0 x28 with 28 from CPU. Up to 44 with Chipset lanes available.
Comparison to Alternatives
Within the EPYC 4005 Series lineup in this catalog, the AMD EPYC 4545P 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.
