01033                             One of the main part of Centrino consists in a brand new CPU,
01034                             the Pentium M, codenamed Banias, that we'll study in this review.
01035                             A particularity of this CPU is that it was designed for mobile platform
01036                             exclusively, unlike previous mobile CPU (Pentium III-M, Pentium 4-M)
01037                             that share the same micro-architecture as their desktop counterparts.
01038                             The Pentium M introduces a new micro-architecture, adapted for mobility
01039                             constraints, and that is halfway between the Pentium III and the Pentium 4.
