ABSTRACT:
A method includes reducing power of a first graphics processor by disabling or not using its rendering engine and leaving a display engine of the same first graphics processor capable of outputting display frames from a corresponding first frame buffer to a display. A display frame is rendered by a second graphics processor while the rendering engine of the first graphics processor is in a reduced power state, such as a non-rendering state. The rendered frame is stored in a corresponding second frame buffer of the second graphics processor, such as a local frame buffer and copied from the second frame buffer to the first frame buffer. The copied frame in the first frame buffer is then displayed on a display while the rendering engine of the first graphics processor is in the reduced power state. Accordingly thermal output and power output is reduced with respect to the first graphics processor since it does not do frame generation using its rendering engine, it only uses its display engine to display frames generated by the second graphics processor.
