## Long description

AMD EPYC 9555 is a server-class processor in the 5th Gen AMD EPYC 9005 family, designed to accelerate data center, cloud and AI workloads. Operating at a base frequency of 3.2 GHz with a boost up to 4.4 GHz and featuring 16 physical cores plus a large 256 MB L3 cache, it uses the Socket SP5 platform and supports high-bandwidth DDR5 memory with dodeca-channel configuration, enabling up to 576 GB/s memory bandwidth for demanding server tasks.
Advantages
The AMD EPYC 9555 offers high per-server performance and energy-efficient operation suitable for dense cloud and AI deployments. Its architecture leverages the EPYC 9005 family capabilities—improved integer performance, efficient multi-core scaling and optimizations for GPU-accelerated systems—allowing reduced rack footprint, lower power draw and potential licensing cost savings compared with legacy hardware.
Suitable for
Virtualization and large-scale cloud instances (vCPU-dense hosts)
AI inference on CPU-only or GPU-accelerated servers for small-to-medium models and analytics
High-throughput database and analytics workloads
Enterprise server applications requiring high memory bandwidth
