'''Skylake W''' ('''Skylake Workstations'''; '''SKL-W''') is codename for [[Intel]]'s enterprise workstation microprocessor line based on the {{intel|Skylake (server)|Skylake|l=arch}} microarchitecture. Skylake W processors feature a large array of enhancements and improvements including the new {{x86|AVX-512}} extension. In addition to being fabricated on Intel's [[14 nm process|enhanced 14+ nm process]], those units also incorporate two full {{x86|AVX-512}} units, a feature otherwise only found on the high-end {{intel|Skylake SP|server|l=core}} models. Skylake W effectively succeeds the previously {{\\|Broadwell EP}}-based {{intel|Xeon E5}}-1600 series processors under the new {{intel|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 {{intel|Socket R4}} (LGA-2066), manufactured on Intel's [[14 nm process|enhanced 14+ nm process]] based on the {{intel|Skylake (server)|Skylake|l=arch}} microarchitecture. Those are single-socket chips only. Geared toward business workstations, those processors come with all the related features such as {{intel|vPro}}, {{intel|Volume Management Device}} (VMD), and RAS.

=== Common Features ===
All Skylake W processors come with all the features enabled and only [[core count]] and {{intel|frequency behavior|frequency}} being the differentiating feature. It's worth pointing out that the Skylake W come with {{x86|AVX-512}} along with two full execution units, similar to the high-end {{intel|Skylake SP|l=core}} 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:''' {{intel|Speed Shift}}, {{intel|vPro}}, {{intel|VT-x}}/{{intel|EPT}}, {{intel|VT-d}}, {{intel|TBT 2.0}}, {{intel|TSX}}, {{intel|TXT}}, {{intel|SpeedStep}}, {{intel|Identity Protection}}, {{intel|Secure Key}}, {{intel|MPX}}, {{intel|OS Guard}}, and {{intel|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 [[physical core|cores]].
