Succession
Broadwell U Kaby Lake U

Skylake U (SKL-U) is the name of the core for Intel's line of low-power mobile processors based on the Skylake microarchitecture serving as a successor to Broadwell U. These chips are primarily targeted towards light notebooks and laptops, portable all-in-ones (AiOs), minis, and conference rooms. Skylake U processors are fabricated on Intel's 14 nm process and provide a large amount of enhancements over comparable Broadwell models.

Overview

Skylake U based processors are a single-chip solution - the chipset is packaged in the same physical casing as the CPU in a multi-chip package (MCP). Note that some models (the Iris IGPs) are actually a 3 dice chip configuration since they incorporate an on-package cache (OPC) in addition to the hub and CPU. Communication between the separate dies are done via a lightweight On-Package Interconnect (OPI) interface, allowing for 4 GT/s transfer rate. All Skylake U processors use Socket BGA-1356 and all Iris models include 64 MiB of side cache.

Common Features

All Skylake U processors have the following:

• Dual-channel Memory
  • Up to LPDDR3-1866, DDR3L-1600, DDR4-2133
  • Up to 16-64 GiB
• 12x PCIe
• dual-core with 4 threads (Celeron models only have 2 threads as they have Hyper-Threading disabled)
• Everything up to AVX (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX) (not all U models support AVX2)
• Support AHCI, High Definition Audio, 4-6x USB 3.0 ports, 8-10x USB 2.0 ports, 2-4x SATA III, 6x I2C, 3x UART, 1x SDXC
• Graphics
  • HD Graphics 510 (Gen 9.5 LP GT1), HD Graphics 520 (Gen9.5 GT2), or Iris Pro Graphics 540/550 (Gen9.5 GT3e)
  • 3 independent displays supported
  • Base frequency of 350 MHz
  • Burst frequency of 1-1.15 GHz
