AMD EPYC 9355 Processor

The AMD EPYC 9355 is a high-performance server processor built on AMD’s advanced Zen 5 Turin architecture, designed to deliver exceptional efficiency and compute density for modern data centre workloads. Featuring 32 cores and 64 threads, it provides a strong balance of multi-threaded throughput and single-core responsiveness, making it ideal for virtualization, enterprise applications, and AI-optimised infrastructure. With a base clock of 3.55 GHz and boost frequencies reaching up to 4.4 GHz, it ensures consistently high performance across both sustained and burst workloads.

Engineered for demanding server environments, the EPYC 9355 includes a massive 256 MB of L3 cache, helping reduce memory latency and improve data access speeds in heavily parallelised workloads. It is built on a 4nm process node and operates with a default TDP of 280W (configurable up to 300W), balancing high performance with modern power efficiency improvements. Supporting the SP5 socket platform, it integrates seamlessly into AMD’s latest enterprise server ecosystems and supports dual-socket configurations for scalable deployments.

In terms of platform capabilities, the EPYC 9355 delivers cutting-edge connectivity with 12-channel DDR5 memory support up to 6400 MT/s, enabling extremely high memory bandwidth for data-intensive applications. It also provides 128 lanes of PCIe 5.0, offering expansive I/O scalability for GPUs, NVMe storage, and accelerators. With enterprise-grade features such as AMD Infinity Guard security technologies, the EPYC 9355 is designed for secure, high-density compute environments, making it a strong choice for cloud infrastructure, HPC clusters, and modern data-driven workloads.
