Procesador AMD EPYC 9745 2,4 GHz 256 MB L3 Zócalo SP5 Dodeca-Channel DDR5 576 GB/s Tray

AMD EPYC 9745 is a server processor in tray packaging compatible with Socket SP5. Operating at a base frequency of 2.4 GHz and with up to 3.7 GHz boost, this CPU provides 128 cores and 256 MB of L3 cache. Designed for data center, cloud and enterprise workloads, the processor supports dodeca-channel DDR5 memory with up to 576 GB/s peak memory bandwidth, delivering high memory throughput and multi‑threaded performance for virtualization, databases, AI inference on CPU-only servers, and high-performance computing.

Advantages

The EPYC 9745 delivers high core density and memory bandwidth that enable increased per-server performance and consolidation of workloads, reducing rack space, power draw and software licensing needs. Its Zen 5 architecture offers strong integer performance and energy efficiency, and the part is suitable as a host CPU in GPU-accelerated systems to improve overall system throughput. The tray format and Socket SP5 compatibility make it suitable for standard server deployments and cloud infrastructure.

Suitable for

• Virtualization and high-density VM hosting
• Database servers and in-memory workloads
• CPU-based AI inference and model serving (up to medium-sized models)
• GPU-accelerated servers where a high-performance host CPU is required
• High-performance computing and large-scale parallel workloads

How to use

Install the EPYC 9745 into a compatible Socket SP5 motherboard following the server vendor’s installation instructions, apply appropriate CPU cooling and ensure power delivery meets platform requirements (up to the configured TDP for the chosen server configuration). Populate supported DDR5 modules according to the motherboard’s channel population guidelines to achieve dodeca-channel operation and maximum bandwidth. Configure firmware/BIOS settings and update to the latest microcode and platform firmware before deploying workloads.

Recommendations

For best results, use server platforms validated for EPYC 9005 series processors, populate memory symmetrically across channels, and use up-to-date BIOS and OS drivers. When pairing with GPUs, choose a chassis and power subsystem that provide sufficient PCIe lanes and power to preserve GPU and CPU performance. Monitor thermals and power consumption under target workloads to optimize performance and efficiency.
