Zusammenfassung:In an embodiment, a processor includes a core domain with a plurality of cores and a power controller having a first logic to receive a first request to increase an operating voltage of a first core of the core domain to a second voltage, to instruct a voltage regulator to increase the operating voltage to an interim voltage, and to thereafter instruct the voltage regulator to increase the operating voltage to the second voltage. Other embodiments are described and claimed.
