- PowerNow!
PowerNow! is speed throttling and power saving technology of AMD's processors used in
laptop s. The CPU'sclock speed andVCore are automatically decreased when the computer is under low load or idle, to save battery power, reduce heat and noise. The lifetime of the CPU is also extended because of reducedelectromigration , which varies exponentially with temperature.The technology is a concept similar to
Intel 'sSpeedStep technology. The adaptation of PowerNow! for AMD's desktop CPUs is calledCool'n'Quiet . NewerOpteron s also use an adaptation of PowerNow! called "Optimized Power Management."Processors supporting PowerNow!
