AMD EPYC 9355 (Turin, 32-core Zen 5)

The AMD EPYC 9355 is a 32-core, 64-thread server processor built on the fifth-generation Zen 5 microarchitecture and fabricated using TSMC's 4nm-class process node. As part of the Turin generation launched in October 2024, the 9355 features AMD's redesigned Zen 5 core with a wider execution engine, improved branch prediction, enhanced AI inference throughput, and a significantly enlarged instruction window compared to its Zen 4 predecessors. The processor operates at a base clock of 2.8 GHz and boosts up to 4.0 GHz, offering an exceptional balance of sustained throughput and peak single-threaded responsiveness. Each CCD (Core Complex Die) integrates Zen 5 cores with per-core L2 caches of 1 MB and a shared 32 MB L3 cache per CCD, delivering low-latency memory access and superior cache hit rates for database and analytics workloads.

The EPYC 9355 is positioned as a strategic choice for enterprises running commercially licensed software such as Oracle Database, Microsoft SQL Server, and SAP HANA, where per-core licensing models make core count a direct cost driver. With 32 cores, the 9355 provides a meaningful reduction in license exposure compared to higher-core-count EPYC SKUs, while still delivering competitive aggregate throughput due to Zen 5's architectural IPC improvements. The processor supports eight channels of DDR5-6000 memory with a maximum capacity of 3 TB per socket, enabling memory-intensive in-memory databases and large dataset analytics without compromise. PCIe 5.0 connectivity with 128 lanes per socket ensures full-bandwidth access to NVMe storage arrays, high-speed network adapters, and GPU accelerators.

Designed for single- and dual-socket server configurations on the SP5 platform, the EPYC 9355 offers broad compatibility with platforms from Dell, HPE, Lenovo, and Supermicro. Its 200W TDP ensures efficient operation within standard 1U and 2U chassis thermal envelopes, and AMD's Infinity Guard security suite — encompassing Secure Encrypted Virtualization (SEV-SNP), Secure Memory Encryption (SME), and AMD Shadow Stack — provides hardware-enforced security primitives essential for regulated industries including financial services, healthcare, and government.

Ideal for

• Oracle Database deployments where per-core licensing makes the 32-core count economically optimal versus higher-density SKUs
• Microsoft SQL Server OLTP environments requiring high per-core performance and large DDR5 memory capacity for buffer pool optimization
• SAP HANA scale-up in-memory analytics leveraging eight-channel DDR5-6000 and up to 3 TB per-socket memory addressability
• Virtualized infrastructure with VMware vSphere or Red Hat OpenShift where Zen 5 IPC improvements increase VM density per licensed core
• High-frequency trading and financial risk calculation requiring low-latency, high-single-thread boost performance up to 4.0 GHz
• Confidential computing workloads in regulated industries utilizing AMD SEV-SNP for hardware-isolated, encrypted virtual machine execution
