AMD EPYC 7643 48 Cores 96 Threads 3.6GHz SP3 100-000000326 Server CPU

High-Density SP3 Server CPU Architecture with AMD EPYC 7643 for Dual-Socket Milan Platforms (SKU 100-000000326)

The AMD EPYC 7643 is a 3rd Gen EPYC 7003 “Milan” processor for SP3 (LGA4094) server platforms, designed to deliver high core density and predictable throughput in 1S and 2S nodes. Built on Zen 3, the AMD EPYC 7643 targets consolidation-focused estates where thread capacity, cache efficiency, and deterministic scheduling directly influence VM density and database performance.

For memory-centric workloads, the AMD EPYC 7643 leverages DDR4-3200 ECC server memory to sustain bandwidth for HPC codes and data platforms while maintaining strong capacity scaling up to 4TB (platform-dependent). PCIe 4.0 with up to 128 lanes per socket enables balanced expansion for high-speed networking, NVMe storage, and accelerator attach, reducing I/O contention in multi-tenant environments. The architecture aligns well with NVMe-centric storage topologies and modern fabric designs where lane availability and latency are decisive engineering constraints.

Why Choose the AMD EPYC 7643?

The AMD EPYC 7643 offers an efficient density-to-performance profile for enterprises standardizing on SP3 dual-socket servers, enabling scale-up capability without sacrificing per-node consolidation. With a mature platform ecosystem, the AMD EPYC 7643 supports repeatable deployments across clusters, simplifies capacity planning, and provides a stable base for mixed virtualization, database, and HPC scheduling requirements.

AMD designs EPYC server CPUs around predictable platform longevity, enterprise-grade RAS expectations, and secure virtualization primitives. With features such as AMD-V and hardware-accelerated cryptography, AMD EPYC 7643 deployments can align with modern data center security baselines while maintaining operational consistency across fleet rollouts.

Key Applications:

• Virtualized compute clusters (1S/2S)
• Database and scale-up transaction processing
• HPC and memory-bandwidth-driven workloads
• NVMe-intensive software-defined storage nodes
• Secure multi-tenant private cloud
