AMD EPYC 9655 96 Cores 192 Threads 4.5GHz SP5 100-000000674 Server CPU

High-Density Dual-Socket Server CPU Architecture built on AMD Turin with the AMD EPYC 9655 / 100-000000674

The AMD EPYC 9655 is a 5th Gen EPYC “Turin” server CPU for the SP5 (LGA6096) platform, engineered for 2-socket deployments where core density and memory bandwidth must scale predictably across enterprise clusters. With 96 cores and 192 threads, the AMD EPYC 9655 targets consolidation-heavy virtualization nodes and parallel technical compute, while maintaining deterministic performance under mixed scheduling and NUMA-aware designs.

Built on a 4nm process, the AMD EPYC 9655 supports DDR5 up to 6000MT/s with ECC and up to 6TB memory per socket, enabling large in-memory datasets and high-VM density without premature paging. Platform I/O provides up to 128 PCIe lanes (platform-dependent) for high-throughput NVMe storage, GPU accelerators, and modern NICs, allowing balanced expansion for storage and east-west traffic. Large on-die cache (96MB L2 and 384MB L3) improves locality for database, analytics, and HPC codes that benefit from reduced memory latency.

Why Choose the AMD EPYC 9655?

The AMD EPYC 9655 delivers a strong density-to-performance profile for SP5 dual-socket servers, simplifying standardization across private cloud, scale-up analytics, and CPU-bound HPC partitions. The architecture supports scalable memory footprints, high I/O fan-out, and enterprise-grade security for repeatable deployments, while the 400W TDP makes thermal design an explicit, manageable engineering decision.

AMD designs EPYC processors with a focus on platform longevity, predictable server qualification, and data-centre-aligned features such as AMD Infinity Guard, AMD-V, AES-NI, and SHA acceleration to support secure multi-tenant operation and compliant infrastructure builds.

Key Applications:

• Virtualization and private cloud compute nodes
• HPC and technical parallel simulation
• Database and in-memory analytics
• High-throughput NVMe storage servers
• Security-focused multi-tenant infrastructure
