AMD PowerNow! is
battery power, reduce heat and noise. The lifetime of the CPU is also extended because of reduced electromigration, which varies exponentially with temperature.[1]
The technology is a concept similar to Intel's SpeedStep technology. The adaptation of PowerNow! for AMD's desktop CPUs is called Cool'n'Quiet. Newer Opterons also use an adaptation of PowerNow! called Optimized Power Management.
AMD has supplied and supported drivers for its PowerNow! technology that work on Windows 98, ME, NT, and 2000.[2][3]
