AMD PowerNow!
Sign in to saveAlso known as PowerNow!
__NOTOC__ AMD PowerNow! was AMD's dynamic frequency scaling and power saving technology targeted at mobile and embedded microprocessors. It allows for the core voltage and frequency to be controlled on-the-fly by the host operating system, or BIOS for embedded systems. PowerNow! was introduced with AMD's embedded processors using their K6 architecture, with the goal to combat the ever-increasing power demands and heat output with microprocessors at the time.

__NOTOC__ AMD PowerNow! was AMD's dynamic frequency scaling and power saving technology targeted at mobile and embedded microprocessors. It allows for the core voltage and frequency to be controlled on-the-fly by the host operating system, or BIOS for embedded systems. PowerNow! was introduced with AMD's embedded processors using their K6 architecture, with the goal to combat the ever-increasing power demands and heat output with microprocessors at the time.
The technology is similar in concept to Intel's first generation SpeedStep technology. However, at the time PowerNow! was released, Intel's SpeedStep only allowed the system to step between two predefined states for core voltage and frequency (high and low). This is in contrast to AMD's implementation which allowed for up to 32 customizable settings for core voltage and frequency, with steps as small as 25 or 50 mV and 33 to 55 MHz respectively. The core frequency itself can also be controlled independently.
