Broadwell DT Kaby Lake DT

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:

• Dual-channel Memory
  • Up to DDR3L-1600, DDR4-2133
  • Up to 64 GiB
  • Has ECC support
• 16x PCIe (4 of the 20 are used by the bus as described above)
• quad-core with 4 to 8 threads (not all DT models support Hyper-Threading)
• Everything up to AVX2 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX, FMA3, and AVX2)
• Has support for Turbo Boost 2.0, vPro, VT-x, VT-d/EPT, TSX, SpeedStep, Identity Protection, Secure Key, Software Guard (SGX), Memory Protection (MPX), OS Guard, TXT
• Graphics
  • HD Graphics P530 (Gen9.5 GT2)
  • Base frequency of 400 MHz
  • Burst frequency of 1.15 GHz
