Kaby Lake R (KBL-R) is the name of the core for Intel's line of low-power mobile processors based on the Kaby Lake microarchitecture serving as a refresh to Kaby Lake U. These chips are primarily targeted towards light notebooks and laptops, portable all-in-ones (AiOs), minis, and conference rooms. Kaby Lake R processors are fabricated on Intel's 2nd generation enhanced 14nm+ process and feature double the core count of the previous generation.

Overview

Kaby Lake R 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). Unlike Kaby Lake U, there are no variations with 3 dies which incorporated 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 Kaby Lake R processors use Socket BGA-1356.

Common Features

All Kaby Lake R processors have the following:

• Dual-channel Memory
  • Up to DDR4-2400, LPDDR3-2133
  • 32 GiB
• 12x PCIe
• quad-core with 8 threads
• Everything up to AVX2 (SMM, FPU, NX, MMX, SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AES, AVX1, 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 620 (Gen9.5 GT2)
  • 3 independent displays supported
  • Base frequency of 350 MHz
  • Burst frequency of 1-1.15 GHz
