摘要:
Systems, methods, and computer readable media to manage power for a graphics processor are described. When the power management component determines the graphics processor is idle when processing a current frame by the graphics processor, the power management component predicts an idle period for the graphics processor based on the work history. The power management component obtains a first latency value indicative of a power on time period and a second latency value indicative of a power off time period for a graphics processor component, such as graphics processor hardware. The power management component provides power instructions to transition the graphics processor component to the power off state based on a determination that a combined latency value of the first latency value and the second latency value is less than the idle period.
