A method of graphics processing comprising receiving, at a graphics processing unit (GPU), a command stream, the command stream including one or more commands to be performed by the GPU and at least one command stream hint, the at least one command stream hint providing a characterization of a workload of the command stream, performing, by the GPU, a power management process based on the at least one command stream hint prior to executing the command stream, and executing, by the GPU, the command stream.

Characterizing GPU workloads and power management using command stream hinting

A device for processing data includes a processing unit configured to predict an execution time of a compute kernel on a secondary processing unit and, based on the predicted execution time, make a power management decision for the secondary processing unit.

Prediction-based power management strategy for GPU compute workloads

Example implementations and techniques are described in which a processor uses a dynamic adjustment algorithm, including algorithms based on performance and energy models, to readjust frequency settings for a graphics processing unit (GPU), and independently for a system memory or for a system memory bus, to an optimal level for meeting sustained performance requirements with the low level of power consumption.

Energy aware dynamic adjustment algorithm

Techniques are described in which a processor determines how busy a graphics processing unit (GPU) was in rendering a current fame based on a time interval between when the GPU completed the rendering of the current frame and when the GPU completed the rendering of a previous frame that immediately precedes the current frame. The processor sets a clock rate of the GPU based on the determination of how busy the GPU was in rendering the current frame.
