The graphics processing units (GPUs) in mobile devices have come a long way in terms of their capabilities to accelerate both graphics- and general-purpose applications. However, they also consume a significant amount of power when executing such applications. This necessitates sophisticated power management techniques for the GPUs in order to save power and energy in mobile devices that typically have limited power budget and battery capacity.

In this chapter, we first discuss the advantages and limitations of the state-of-the-art power management techniques for both gaming- and general-purpose ...
