Processador AMD EPYC 9355 3,55 GHz 256 MB L3 Socket SP5

Processor AMD EPYC 9355 3.55 GHz with 256 MB L3 cache is a server-class CPU based on the 5th Gen AMD EPYC family. Designed for data center, cloud and AI workloads, the EPYC 9355 uses the SP5 socket and supports dodeca-channel DDR5 memory for high memory bandwidth and capacity, enabling efficient handling of compute-intensive and multi-threaded server tasks.

Advantages

The AMD EPYC 9355 offers high core density (32 cores) and a large 256 MB L3 cache to improve throughput on server workloads. With a base frequency of 3.55 GHz and boost up to 4.4 GHz, it delivers strong single-thread and multi-thread performance. Support for dodeca-channel DDR5 memory provides up to 576 GB/s memory bandwidth, which helps reduce bottlenecks in memory-bound applications. The EPYC 9355 is built for energy-efficient, high-density deployments typical for cloud and AI inference use cases.

Suitable for

• Virtualization and cloud infrastructure (vCPU-dense hosts)
• AI inference on CPU-only servers and hybrid CPU+GPU systems
• High-performance computing and data analytics
• Database servers and large-scale transaction processing
