WORKING CPU FROM WORKING XEON SERVER.
POWERFUL 8-CORE CPU (16 THREADS)!
The Intel Xeon W-2140B was a server/workstation processor with 8 cores, launched in December 2017. It is part of the Xeon W lineup, using the Skylake-W architecture with Socket 2066. Thanks to Intel Hyper-Threading the core-count is effectively doubled, to 16 threads. Xeon W-2140B has 11MB of L3 cache and operates at 3.2 GHz by default, but can boost up to 4.2 GHz, depending on the workload. Intel is building the Xeon W-2140B on a 14 nm production process, the transistor count is unknown. The multiplier is locked on Xeon W-2140B, which limits its overclocking capabilities.
With a TDP of 120 W, the Xeon W-2140B consumes a lot of power, so good cooling is definitely needed. Intel's processor supports DDR4 memory with a quad-channel interface. The highest officially supported memory speed is 2666 MHz, but with overclocking (and the right memory modules) you can go even higher. 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 W-2140B uses a PCI-Express Gen 3 connection. This processor lacks integrated graphics, you might need a graphics card.
Hardware virtualization is available on the Xeon W-2140B, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel has added support for the newer AVX2 and AVX-512 instructions, too.
