System, apparatus and method for dynamically adjusting platform power and performance based on task characteristics

A processor, comprising:

• a plurality of cores including a first plurality of cores and a second plurality of cores, the second plurality of cores comprising relatively lower power cores than the first plurality of cores;
• graphics processing circuitry to perform graphics operations;
• a memory controller to couple the plurality of cores and the graphics processing circuitry to a memory;
• and
• power control circuitry to control power consumption of the plurality of cores and the graphics processing circuitry, the power control circuitry to determine background task metric information based on a first amount of time that at least one core of the plurality of cores executed background tasks during an active duration, the power control circuitry to dynamically apply a power management policy for a background mode when the background task metric information exceeds a first threshold, the power management policy for the background mode to reduce power consumption of at least the processor.
