Abstract

In one embodiment, a processor has multiple cores to execute threads. The processor further includes a power control logic to enable entry into a turbo mode based on a comparison between a threshold and value of a counter that stores a count of core power and performance combinations that identify turbo mode requests of at least one of the threads. In this way, turbo mode may be entered at a utilization level of the processor that provides for high power efficiency. Other embodiments are described and claimed.
