AMD EPYC 9555P SP5 Tray - 100-000001523 Processor

The AMD EPYC 9555P is a single-processor server CPU from the EPYC 9005 „Turin“ series, aimed at serious data center, cloud, and AI workloads. You get 64 physical cores and 128 threads based on Zen 5 architecture at a base frequency of 3.2 GHz and Turbo up to 4.4 GHz, which is a combination of serious multi-core capacity and high single-core frequency. It is built on a 4 nm process with a massive 256 MB cache and a TDP of 360 W. It comes in a Tray variant, without an included cooler and without integrated graphics (iGPU), so the configuration around it must be well thought out.

What you get

With 64 cores and 128 threads, you have raw resources for virtualization, large-scale databases, high-density containers, and analytical workloads that favor parallelism. The high Turbo frequency up to 4.4 GHz helps with latency-sensitive workloads – for example, parts of an AI inference pipeline or individual services in a microservices architecture. Support for DDR5 with a 12-channel controller and speeds up to 6400 MT/s, including DDR5 ECC Registered and DDR5 3DS RDIMM/LRDIMM, provides enormous bandwidth and memory capacity, which are critical for in-memory databases, caching, and large models. The 256 MB cache reduces the need for frequent accesses to RAM, stabilizing performance under heavy mixed load. A TDP of 360 W requires serious cooling and a well-sized power supply, but it gives you the freedom to push the CPU to its limit in a 1P server scenario.

• 64 physical cores and 128 threads provide massive parallelism for virtualization, containerization, and heavy multi-threaded services.
• Frequency of 3.2 GHz with Turbo up to 4.4 GHz combines stable base performance with a high peak for latency-sensitive tasks.
• 256 MB cache memory helps keep active working sets closer to the CPU, reducing access to RAM under mixed workloads.
• DDR5, 12-channel controller, up to 6400 MT/s provide enormous memory bandwidth for in-memory services and AI/analytical applications.
• Support for DDR5 ECC Registered and DDR5 3DS RDIMM/LRDIMM allows for large and reliable memory configurations for data center environments.
• TDP 360 W means serious capacity under full load, but requires quality server cooling and a well-sized platform.
• EPYC 9005 „Turin“, Zen 5, Socket SP5, 1P position it as a modern single-processor server CPU for data center, cloud, and AI workloads.

Who it is suitable for

This EPYC is for you if you are building a serious 1P server for virtualization, a cloud platform, databases, analytical workloads, or AI inference, where the number of cores and memory bandwidth are directly monetized. It is suitable for data center and enterprise environments where resource density in a single socket is sought. It is not really suitable for home labs with a limited budget or light office workloads – it would be an outright overkill.

The strongest aspect here is the combination of 64 Zen 5 cores, a 12-channel DDR5 controller up to 6400 MT/s, and 256 MB cache in a 1P SP5 platform – a serious foundation for a modern server in the cloud or data center with a focus on scalable, multi-threaded services.
