Introduced in March 2003, the Pentium M is an x86 (i686) architecture microprocessor designed and manufactured by Intel and forms part of the Intel Centrino platform. The processor was originally designed for use in laptop personal computers, thus the "M" for mobile. It was codenamed "Banias" before its introduction.
Intel launched its improved Pentium M, formerly known as Dothan, on May 10, 2004. Dothan Pentium M processors are among the first Intel processors to be identified using a "processor number" rather than a clockspeed rating, and the mainstream versions are known as Pentium M 715 (1.5 GHz), 725 (1.6 GHz), 735 (1.7 GHz), 745 (1.8 GHz), 755 (2.0 GHz), and 765 (2.1 GHz).
These 700 series Pentium M processors retain the same basic design as the original Pentium M, but are manufactured on a 90 nm process, with twice the secondary cache. Die size, at 84 mm², remains in the same neighborhood as the original Pentium M, even though the 700 series contains ~140 million transistors, most of which make up the massive 2 MB cache. TDP is also down to 21 watts (from 24.5 watts in Banias), though power use at lower clockspeeds has increased slightly.
