Pentium M
is x86 architecture based microprocessor introduced in March 2003.
designed for use in mobile computers such as laptops. It was code named "Banias". It is a modified version of the Pentium III design (itself based on the Pentium Pro core design).
optimized for power efficiency, running with very low average power consumption and much lower heat output than desktop processors.
runs at a lower clock speed when compared to the contemporary Pentium 4 desktop processor series, but with similar performance. (E.g. a 1.6 GHz Pentium M can typically attain or exceed the performance of a 2.4 GHz Northwood Pentium 4).
Other power saving methods include dynamically variable clock frequency and core voltage, letting the Pentium M to run slowly (typically 600 MHz) when the system is idle to conserve energy.
