Intel 6 Core E5-2643v4 (3.40GHz, 20M, 9.6GT/s, 135W) SR2P4

This Intel Xeon E5-2643 v4 processor is a Broadwell-generation server CPU for Intel Xeon E5 v4 platforms using the FCLGA2011 socket. It provides 6 cores and 12 threads with a 3.40GHz base frequency, up to 3.70GHz turbo frequency, 20MB cache, 9.6GT/s QPI, and a 135W TDP, making it appropriate for server workloads that prioritize higher per-core speed over maximum core count. The processor supports ECC DDR4 memory up to 2400MHz across four memory channels, provides 40 PCIe 3.0 lanes, and supports up to 2-socket operation when paired with a motherboard, BIOS, heatsink, fan configuration, memory population, and system thermal design that support this CPU generation and wattage.
