Pentium M:

The Pentium M brand refers to only two single-core 32-bit x86 microprocessors (with the Intel P6 microarchitecture) introduced in March 2003 (during the heyday of the Pentium 4 desktop CPUs), and forming a part of the Intel Centrino platform. The Pentium M branded processors had a maximum power consumption (TDP) of 3-25 W, and were intended for use in laptop personal computers (thus the "M" moniker standing for mobile). They evolved from the core of the last Pentium III branded CPU by adding the bus interface of Pentium 4 one, an improved instruction decoding/issuing front end, improved branch prediction, SSE2 support, and a much larger cache. The first Pentium M branded CPU, codenamed the Banias, was followed by the second one - the Dothan. After the Pentium M branded processors, Intel released the Core branded dual-core mobile Yonah CPU with a modified microarchitecture. Pentium M branded CPUs can be considered as the end of the Intel P6 microarchitecture.
