Succession

Skylake DT (SKL-DT) is the name of the core for Intel's workstations and entry-level servers line of processors based on the Skylake microarchitecture serving as a successor to Broadwell DT. These chips are primarily targeted towards professional-grade workstation and entry-level servers. Skylake DT processors are fabricated on Intel's 14 nm process and provide a large set of improvements over comparable Broadwell models.

Overview

Skylake DT based processors are a 2-chip solution - the microprocessor and the chipset. Those processors are Socket LGA-1151 and use Sunrise Point chipset (HUB). The microprocessor is connected to the chipset via 4 of the chip's 20 PCIe lanes using Intel's proprietary Direct Media Interface 3.0 (DMI 3.0), allowing for 8 GT/s transfer rate per lane.


Common Features

All Skylake DT processors have the following:
