A method and apparatus for controlling the power usage of a processor is disclosed. The power usage of the processor is monitored. When the power usage of the processor exceeds a threshold power usage value, the power used by the processor is reduced or limited. A processor utilization value is also monitored. When the processor utilization value is above a threshold utilization value, the processor is ramped to a higher performance state. When power to the processor is being limited, a first rate is used to ramp the processor to the higher performance state. When power to the processor is not being limited, then a second rate, different from the first rate, is used to ramp the processor to the higher performance state.
