Core M is a family of Consumer Ultra-Low Voltage (CULV) x86 microprocessors introduced by Intel in 2014. Core M microprocessors have ultra-low power (TDP ≤ 4.5 Watts) designed specifically for ultra-thin notebooks and other mobile devices that run fanless.

Overview

Core M is family designed by Intel that directly targets fanless ultra-thin mobile devices with stringent voltage and power restrictions. Unlike the Atom (also x5, x7, et al) which has its own specially designed microarchitecture (e.g. Airmont), the Core M uses Intel's mainstream microarchitectures (e.g. Broadwell & Skylake) in an attempt to elevate performance while still delivering sub-4.5W TDP. The end result is a processor that has reasonable performance and features compared to an Atom, but a premium.

Core M dies are packaged with the Platform Controller Hub (PCH) die in the same packaging which is only about 1 mm thick and requires no fan.

With Kaby Lake, Intel rebranded "M5" and "M7" simply as "i5" and "i7". Intel stated the change took place as an attempt to reduce confusion between the Core m and Core i5/7 families
