1. A processor comprising:
a plurality of cores;
at least one integrated voltage regulator to receive a first voltage from an external voltage regulator and provide a regulated voltage to at least one of the plurality of cores;
a control circuit coupled to the at least one integrated voltage regulator, wherein in a first mode the control circuit is to cause the regulated voltage from the at least one integrated voltage regulator to be provided to at least some of the plurality of cores, and in a second mode to cause a bypass voltage from the external voltage regulator to be provided to the at least some of the plurality of cores; and
a power controller to determine an operating voltage for the plurality of cores, the power controller including bypass circuitry, in the second mode, to cause the bypass voltage to be provided to the at least some of the plurality of cores and cause the at least one integrated voltage regulator to be bypassed.
