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[edit]

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[edit]

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:

Skylake W Processors[edit]

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.
