1. A multi-core processor for executing a task, comprising: a plurality of processing cores; turbo mode logic to control the plurality of processing cores such that an active processing core transitions into a turbo mode by operating at a higher frequency while an idle processing core remains idle; performance computing logic to calculate potential performance losses associated with selecting among the plurality of processing cores for handling an event, wherein said potential performance losses comprise an active performance loss (APL) for selecting the active processing core to handle the event and a waking performance loss (WPL) for selecting the idle processing core to handle the event, wherein the APL is based on a ratio of a time period for executing the task and a total runtime of both the task and a program workload being executed by the active processing core; and task routing logic to select between the active processing core and the idle processing core for executing a task to handle the event, said selection based on a comparison between the APL and the WPL, wherein power is channeled to wake up the idle processing core unless the comparison indicates that the APL is less than the WPL.
