Skylake W (SKL-W) is the processor core 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.

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

All 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. 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).
