The Xeon E5-2643 v4 is a 64-bit hexa-core x86 microprocessor introduced by Intel in 2016. This server MPU is designed for frequency-optimized 2S environments (2U square form factor). Operating at 3.4 GHz with a turbo boost frequency of 3.7 GHz for a single active core, this MPU has a TDP of 135 W and is manufactured on a 14 nm process (based on Broadwell).
