Processor AMD EPYC 9825 2.2 GHz 384 MB L3 Socket SP5

Processor AMD EPYC 9825 operates at a base frequency of 2.2 GHz with up to 3.7 GHz boost and features a large 384 MB L3 cache. Part of the 5th Gen AMD EPYC family and compatible with Socket SP5, this server-class CPU provides up to 144 cores and supports dodeca-channel DDR5 memory with a maximum theoretical memory bandwidth of 576 GB/s, making it suitable for dense virtualized, cloud and AI workloads that require high core counts, memory capacity and energy-efficient performance.

Advantages

The AMD EPYC 9825 offers high core density (144 cores) and a substantial L3 cache, delivering strong integer and multithreaded performance for server workloads. Support for Socket SP5 and dodeca-channel DDR5 memory enables high memory bandwidth and capacity. The processor is designed to provide improved per-server performance and energy efficiency compared with previous generations, helping reduce rack count, power consumption and total cost of ownership for dense deployments.

Suitable for

• Virtualization and cloud infrastructure (large numbers of vCPUs)
• CPU-only AI inference for medium-sized language and image models
• High-performance compute and enterprise server applications
• GPU-host systems where a high-core-count host CPU is required
