AMD EPYC 9555 64 Cores 128 Threads 4.4GHz SP5 100-000001142 Server CPU

High-Density Server CPU Platform Core featuring PCIe 5.0 I/O and DDR5 ECC with the AMD EPYC 9555 (SKU 100-000001142)

The AMD EPYC 9555 is a 5th Gen AMD EPYC “Turin” processor for the SP5 (LGA6096) socket, designed for dual-socket enterprise platforms where core density, memory bandwidth, and I/O throughput must scale predictably. With 64 cores and 128 threads per CPU, the AMD EPYC 9555 aligns to consolidation-heavy virtualisation clusters, private cloud nodes, and CPU-focused HPC deployments that prioritise deterministic performance per rack unit.

Built for modern DDR5 ECC memory architectures up to 6000 MT/s, the AMD EPYC 9555 supports large, reliable memory footprints for database buffer pools, in-memory analytics, and VM density, while maintaining strong isolation and integrity characteristics expected in production environments. The PCIe 5.0 I/O platform delivers 128 lanes for high-speed expansion, enabling dense NVMe storage tiers, high-bandwidth NICs, and accelerator connectivity without oversubscription. The 2-socket scalability profile allows architects to balance licensing, NUMA topology, and throughput, while the tray format supports standard data centre thermal and serviceability practices.

Why Choose the AMD EPYC 9555?

The AMD EPYC 9555 provides an efficient density-to-performance ratio for 2S server designs by combining high core counts, enterprise memory reliability, and a PCIe 5.0 lane budget suited to storage- and network-heavy nodes. The AMD EPYC 9555 is a strong fit when you need predictable scaling across clusters, consistent latency characteristics for scale-up analytics, and platform headroom for future NVMe and fabric upgrades.

AMD engineering emphasises data centre standardisation, long-life server platforms, and built-in security capabilities, including AMD Infinity Guard and instruction-level cryptographic acceleration, to support regulated environments and hardened virtualisation stacks.

Key Applications:

• Dual-socket virtualisation and private cloud
• Scale-up databases and analytics
• Dense NVMe storage and high-speed I/O servers
• HPC CPU compute nodes
