is AMD's dynamic frequency scaling and power saving technology for laptop processors.

The CPU's clock speed and VCore 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 reduced electromigration, which varies exponentially with temperature.

for AMD's desktop CPUs is called Cool'n'Quiet.

AMD has supplied and supported drivers for its PowerNow!
