AMD EPYC 7643P 48 Cores 96 Threads 3.6GHz SP3 (LGA 4094) 100-000001285 Server CPU

High-Density 1S Server CPU Platform featuring PCIe 4.0 I/O and large cache with the AMD EPYC 7643P (SKU 100-000001285)

The AMD EPYC 7643P is a 3rd Gen AMD EPYC 7003 “Milan” processor designed for 1-socket enterprise servers where consolidation, predictable throughput, and platform simplicity matter. With 48 cores and 96 threads, the AMD EPYC 7643P targets virtualisation hosts, private cloud nodes, and CPU-optimised parallel workloads that benefit from high core density and strong per-socket capability.

Architecturally, the AMD EPYC 7643P combines substantial on-die cache (24MB L2 and 256MB L3) with ECC memory support and scalable memory capacity up to 4TB, enabling larger in-memory datasets and reduced dependency on storage latency. For expansion, 128 PCIe 4.0 lanes enable high-bandwidth attachment of NVMe storage, DPUs, and accelerator-class devices without introducing external I/O bottlenecks, supporting balanced designs for analytics, database, and HPC nodes. Hardware virtualisation (AMD-V) and instruction-set acceleration for encryption and integrity (AES-NI, SHA) align the platform with secure multi-tenant environments.

Why Choose the AMD EPYC 7643P?

The AMD EPYC 7643P delivers a compelling density-to-performance ratio in a 1S footprint, enabling standardised server builds with fewer sockets while maintaining substantial compute headroom. The platform’s PCIe 4.0 lane budget and large cache help scale out clusters with consistent per-node behaviour, while the 240W thermal profile supports engineered airflow planning in rack deployments. For organisations seeking streamlined licensing and operational simplicity, the AMD EPYC 7643P is optimised for scalable, repeatable infrastructure blocks.

AMD designs EPYC processors with a focus on datacentre reliability, secure virtualisation, and strong I/O architecture to match modern storage and accelerator connectivity requirements, supporting enterprise lifecycle planning and platform consistency.

Key Applications:

• Virtualisation and VM consolidation
• Private cloud compute nodes
• Database and OLTP servers
• Analytics and in-memory processing
• CPU-optimised HPC workloads
