Abstract
A method for maximizing the performance versus the power consumption of a computer system. The method uses a CPU which has the ability to select an optimum external to internal clock frequency ratio. By changing the external to internal clock frequency ratio, the computer system is able to decrease the internal clock frequency in order to conserve power, while allowing the external clock frequency to be at an optimum level in order to maintain maximum system performance.
