Processor AMD EPYC 9555P 3,2 GHz 256 MB L3 Socket SP5

5th Gen AMD EPYC processors are purpose-built server CPUs designed to accelerate data center, cloud, and AI workloads. The AMD EPYC 9005 series delivers high core counts, optimized memory bandwidth, and energy-efficient performance for both CPU-only and GPU-accelerated systems, supporting scalable virtualisation and demanding inference tasks.

Advantages

AMD EPYC 9005 offers high integer and AI inference performance with up to 192 Zen 5/Zen 5c cores per processor, enabling greater per-server throughput and higher virtual CPU density. The family includes variants tuned as host CPUs for GPU servers to improve overall system throughput and return on investment. These processors prioritize energy efficiency and lower total cost of ownership while reducing rack space and power consumption compared with legacy hardware.

Key specifications

• Microarchitecture: Zen 5 / Zen 5c cores
• Maximum cores per socket: up to 192 cores
• Target workloads: data center, cloud, AI inference, GPU-accelerated systems
• Performance highlights: leadership integer performance and up to 2x inference throughput vs previous generation on certain configurations
• Density: supports higher vCPU counts (example: AMD EPYC 9965 supports ~33% more vCPUs vs a 144-core competitor)
• Efficiency: optimized for energy efficiency and reduced TCO

How to use

Deploy AMD EPYC 9005 processors in rack or blade servers configured for your target workload: choose CPU-only servers for efficient inference of language models up to mid-sized parameter counts and image or fraud analysis, or select host-CPU variants paired with multiple GPUs for large-model inference and training acceleration. Match processor SKU and memory configuration to your virtualisation and AI requirements, and follow vendor guidelines for cooling, power delivery, and firmware to ensure stable operation and optimal performance.
