Pentium M

The Pentium M is Intel's family of mobile 32-bit single-core x86 microprocessors based on the sixth-generation P6 microarchitecture introduced in March 2003 and forming a part of the Intel Carmel notebook platform under the then new Centrino brand. The Pentium M processors had a maximum thermal design power (TDP) of 5–27 W depending on the model, and were intended for use in laptops (thus the "M" suffix standing for mobile). They evolved from the core of the last Pentium III–branded CPU by adding the front-side bus (FSB) interface of Pentium 4, an improved instruction decoding and issuing front end, improved branch prediction, SSE2 support, and a much larger cache. The Pentium M replaced the laptop version of the Pentium 4 (the Pentium 4-Mobile, or P4-M), which suffered from power consumption and heat problems. The first Pentium M–branded CPU, code-named Banias, was followed by Dothan. The Pentium M line was removed from the official price lists in July 2009, when the Pentium M-branded processors were succeeded by the mobile Pentium Dual-Core line.
