Intel recently announced its new technology for mobile platforms,
named Centrino, and presents it as a big advance in mobile PCs.
One of the main part of Centrino consists in a brand new CPU,
the Pentium M, codenamed Banias, that we'll study in this review.
A particularity of this CPU is that it was designed for mobile platform
exclusively, unlike previous mobile CPU (Pentium III-M, Pentium 4-M)
that share the same micro-architecture as their desktop counterparts.
The Pentium M introduces a new micro-architecture, adapted for mobility
constraints, and that is halfway between the Pentium III and the Pentium 4.
