Skylake W (Skylake Workstations; SKL-W) is codename for Intel's enterprise workstation microprocessor line based on the Skylake microarchitecture. Skylake W processors feature a large array of enhancements and improvements including the new AVX-512 extension. In addition to being fabricated on Intel's enhanced 14+ nm process, those units also incorporate two full AVX-512 units, a feature otherwise only found on the high-end server models. Skylake W effectively succeeds the previously Broadwell EP-based Xeon E5-1600 series processors under the new Xeon W family.

Overview

Skylake W are enterprise workstation microprocessors. Those are a two-chip solution consisting of the microprocessor and the C422 chipset. All processors are socket Socket R4 (LGA-2066), manufactured on Intel's enhanced 14+ nm process based on the Skylake microarchitecture. Those are single-socket chips only. Geared toward business workstations, those processors come with all the related features such as vPro, Volume Management Device (VMD), and RAS.

Common Features

For the most part, Skylake W processors come with all the features enabled and only core count and frequency being the differentiating feature. It's worth pointing out that the Skylake W come with AVX-512 along with two full execution units, similar to the high-end Skylake SP models (with the exception of the two low-end models). All models have 48 PCIe lanes and have all the following features in common:

Mem: 512 GiB of quad-channel DDR4-2666 ECC Memory
- DPC RDIMM and LRDIMM \w ECC
I/O: 48 PCIe 3.0 Lanes
TDP: 120 W / 140 W
ISA: Everything up to AVX-512 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, AVX2, AVX512F, AVX512CD, AVX512BW, AVX512DQ, AVX512VL)
Features: Speed Shift, vPro, VT-x/EPT, VT-d, TBT 2.0, TSX, TXT, SpeedStep, Identity Protection, Secure Key, MPX, OS Guard, and Volume Management Device (VMD).

Skylake W Processors

Note that for the lower core-count models, the L3 cache size is larger than it would otherwise be due to additional cache slices being enabled from disabled cores.
