The
Pentium M is a family of mobile 32-bit single-core
x86 microprocessors (with the modified Intel
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 first Pentium M–branded
CPU, code-named
Banias, was followed by
Dothan. The Pentium M-branded processors were succeeded by the
Core-branded
dual-core mobile
Yonah CPU with a modified microarchitecture.
