Abstract: A system that includes first circuitries to operate at a first clock frequency, second circuitries to operate at a second clock frequency, and circuitry to adjust the first and second clock frequencies. In some examples, the circuitry is to selectively adjust the first and second clock frequencies provided to the respective first circuitries and the second circuitries according to a target ratio based on temperature and power consumption of the first circuitries and the second circuitries, wherein the target ratio is based on clock frequencies of the first circuitries and the second circuitries, stall time of the first circuitries, and dynamic capacitance of the first circuitries and the second circuitries.
