Intel Xeon E5-2643V3 6 Cores 12 Threads 3.7GHz R (LGA 2011) CM8064401724501 Server CPU

High-Frequency 2S Server CPU for LGA2011-3 platforms featuring Haswell-EP architecture with the Intel Xeon E5-2643V3 / CM8064401724501

The Intel Xeon E5-2643V3 is a Haswell-EP, 22nm server processor engineered for 2-socket rack and tower systems that require high per-core frequency for responsive enterprise services. With 6 cores and 12 threads, it targets latency-sensitive compute paths where sustained clock speed and predictable scheduling matter more than maximum core count.

On LGA2011-3 (Socket R3) platforms, the Intel Xeon E5-2643V3 enables DDR4 ECC memory architectures up to 2133MT/s, supporting large, resilient memory footprints for virtualization hosts and infrastructure roles. Integrated PCIe 3.0 connectivity with up to 40 lanes helps maintain balanced I/O for NICs, HBAs, and NVMe-capable adapters, aligning expansion planning with data-path requirements. Storage and network performance scale through platform controllers and add-in cards rather than an integrated GPU, keeping thermals and resources focused on CPU throughput and cache efficiency.

Why Choose the Intel Xeon E5-2643V3?

The Intel Xeon E5-2643V3 delivers a strong density-to-performance profile for 2S deployments where fewer, faster cores reduce licensing exposure and improve single-thread and lightly parallel performance. It supports enterprise reliability features and a proven scalability model for mixed workloads, combining clock speed with virtualization readiness for consistent consolidation and service isolation.

Intel designs Xeon platforms for long lifecycle operation, validated instruction sets, and predictable behavior under sustained load. The architecture aligns with modern data center standards for ECC memory integrity, platform manageability, and hardware-assisted security to support controlled multi-tenant environments.

Key Applications:

• 2-socket virtualization hosts
• Infrastructure services and directory platforms
• High-frequency database front-end tiers
• HPC/light compute nodes with DDR4 ECC
• Network and security appliances
