1. A processor comprising: a plurality of cores of the processor, a first core of the plurality of cores to operate at a first voltage and a second core of the plurality of cores to operate at a second voltage, the second voltage independent of the first voltage; the first core of the plurality of cores to be associated with a first frequency and the second core of the plurality of cores to be associated with a second frequency, wherein the first and second frequencies may be different from each other; a graphics unit of the processor, wherein a driver of the graphics unit is to control execution on the graphics unit; an interconnect of the processor to couple the first core of the plurality of cores, the second core of the plurality of cores and the graphics unit to a memory external to the processor; and a power controller to control a frequency of the interconnect based at least in part on a frequency of the graphics unit, wherein the graphics unit is operable at a first plurality of frequencies and the interconnect is operable at a second plurality of frequencies, and the power controller is to update the frequency of the interconnect to another one of the second plurality of frequencies based at least in part on the frequency of the graphics unit.
