Intel · Xeon W · 2017 · LGA2066
The Intel Xeon W-2191B is a desktop processor with 18 cores, released in 2017 at an MSRP of N/A. It is part of the Xeon W lineup, using the Xeon W platform, and fits the LGA2066 socket. Internally, it is built on the "Skylake-W" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 36 threads for improved parallelism. The Xeon W-2191B has a base clock of 2.3 GHz and can boost up to 4.3 GHz depending on workload and thermal headroom. Intel manufactures the "Skylake-W" silicon on a 14nm process node. Its multiplier is locked, so any overclocking has to come from raising the base clock rather than the multiplier. This processor supports DDR4 memory. With a TDP of 140W, the Xeon W-2191B sits in a typical power envelope for a modern desktop CPU. This processor has no integrated graphics — a discrete GPU is required. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 24.75MB of L3 cache.
Carries Intel's 'B' suffix, denoting a later production stepping of the Skylake-W silicon than the equivalent non-B part — a revision Intel occasionally introduced mid-cycle without a full model refresh.
