Intel : Xeon X5690 Hexa Core PC Processor Multicolour

Circuitry enables processors to conserve energy use and lengthen battery life
Improve everything from performance in specific types of applications to the reliability of the cpu as a whole
SMM circuitry is integrated into the physical chip but operates independently to control the processor's power use based on its activity level
Next few sections take a look at some of these technologies, including system management mode superscalar execution ht technology and dual core processing
Goal of putting faster and more powerful processors in laptop computers has created power-management circuitry
