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.

Although those microprocessors are still based on Kaby Lake, Intel has branded them as 8th Generation Core. Those processors are also the first to feature quad-cores within the 15 Watt TDP class of mobile processors.

Overview[edit]

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[edit]

All Kaby Lake R processors have the following:
