How do the AMD PowerNow! and Cool‘n’Quiet technologies work?
AMD PowerNow! and Cool‘n’Quiet technologies automatically vary processing power seamlessly without impacting performance. When applications do not require maximum processing power, such as word processing software, PCs run in a lower power state. This is made possible by enabling the processor to dynamically switch among multiple performance states (each performance state is a specific frequency/voltage combination), allowing the system to run cooler and quieter while conserving energy. The Microsoft Windows XP operating system can adjust the processor performance state according to software demand.
