The Intel Xeon E5-4627 v2 was a server/workstation processor with 8 cores, launched in Q1 2014. It is part of the Xeon E5 lineup, using the Ivy Bridge-EP architecture with Socket LGA2011. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 16 threads. To further increase overall system performance, up to four Xeon E5-4627 v2 CPUs can work together in a multi-processor (SMP) configuration. Xeon E5-4627 v2 has 16 MB of L3 cache and operates at 3.3 GHz. Intel is building the Xeon E5-4627 v2 on a 22 nm production process using 1.4 billion transistors. The multiplier is locked on Xeon E5-4627 v2, which limits its overclocking potential. With a TDP of 130 W, the Xeon E5-4627 v2 consumes significant power, so adequate cooling is required. Intel's processor supports DDR3 memory with a quad-channel interface, running at speeds up to 1866 MHz. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the system, Xeon E5-4627 v2 uses a PCI-Express Gen 3 connection. This processor lacks integrated graphics, so a dedicated graphics card may be needed. Hardware virtualization is available on the Xeon E5-4627 v2, which greatly improves virtual machine performance. The processor also supports advanced instruction sets including AVX (Advanced Vector Extensions) for improved floating-point performance in demanding computational workloads.
