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 and ultra-thin mobile devices. 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 microarchitecture (e.g. Broadwell & Skylake) for performance while attempting to deliver sub-4.5W TDP while maintaining somewhat acceptable performance that's much better than Atom.

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.
