How Does AMD PowerNow! Technology Work ?

The premise behind AMD PowerNow! technology is a very simple one. Some applications require less processing power than others. Word processing, for example, consumes relatively few processor cycles, but if you run photo editing or other media-rich applications on the same system, more processor cycles will be required for responsive performance.

AMD PowerNow! technology controls your notebook’s level of processor performance automatically, dynamically adjusting the operating frequency and voltage many times per second, according to the task at hand. When an application does not require full performance, significant amounts of power can be saved. However, the processor can “instantaneously” respond to increased workloads, allowing the system to deliver a responsive and rewarding computing experience. The only difference the user will see on most applications is significantly longer battery life. Performance will still be responsive, with maximum processor performance being delivered when required, and automatic power savings when possible. AMD PowerNow! technology even has benefits when you are working at your desk with the notebook on AC power, since the system will typically run cooler and quieter.

和你说的Utility最大的一点区别是电压和频率是自动控制的，用户不能手动修改！
