Processore AMD EPYC 9355P 3,55 GHz 256 MB L3 socket SP5

AMD EPYC 9355P is a 5th-generation server processor built for data center, cloud, and AI workloads. Operating at a base frequency of 3.55 GHz with boost up to 4.4 GHz, this Socket SP5 CPU features 32 Zen 5 cores and a large 256 MB L3 cache. It supports dodeca-channel DDR5 memory with up to 576 GB/s memory bandwidth, making it suitable for demanding server tasks that require high throughput, density, and energy efficiency.

Advantages

The EPYC 9355P delivers strong integer and multi-threaded performance from Zen 5 cores while preserving energy efficiency and total cost of ownership typical of the AMD EPYC 9005 family. Its large L3 cache and wide DDR5 memory channels enable improved per-server performance and high memory throughput for virtualized environments, inference workloads, and CPU-hosted GPU systems. Designed for single-socket deployments, the processor offers a balance of core count and frequency for versatile server configurations.

Suitable for

• Virtualization and cloud infrastructure (vCPU-dense hosts)
• AI inference on CPU-only servers or as host CPU in GPU-accelerated systems
• High-throughput database and analytics workloads
• Enterprise applications requiring energy-efficient, high-density compute

How to use

Install the AMD EPYC 9355P into a compatible Socket SP5 server motherboard following the server vendor’s installation and thermal guidelines. Populate supported DDR5 DIMMs across the dodeca-channel memory topology to achieve optimal memory bandwidth. Configure BIOS/firmware settings recommended by your server vendor for firmware compatibility, power management, and virtualization features. For GPU-accelerated workloads, pair the processor with appropriate PCIe GPU cards and ensure sufficient cooling and power delivery.

Recommendations

For best results in virtualization and AI inference, use high-quality DDR5 memory modules matched to the server vendor’s compatibility list, enable relevant BIOS features (such as NUMA balancing and SMT as appropriate), and follow recommended power and cooling profiles. Use this single-socket EPYC 9355P in systems where a strong balance of cores, frequency, and memory bandwidth is required without dual-socket complexity.
