In one embodiment, the present invention includes a multicore processor having a power controller with logic to dynamically switch a power management policy from a power biased policy to a performance biased policy when a utilization of the processor exceeds a threshold level. Thus at low utilizations, reduced power consumption can be realized, while at higher utilizations, greater performance can be realized. Other embodiments are described and claimed.
