Abstract
A computing device and method controls power consumption of a graphics processing unit in the computing device by the GPU determining an allocated power for the USB device connected through a USB port, such as a USB-C port. The GPU issues allocated power information for the external USB device to cause the allocated power to be provided to the USB device and includes issuing allocated power information to a power delivery (PD) controller that is connected to a USB port. In some implementations, the GPU shifts at least a portion of the allocated power from the USB device back to the GPU in response to a usage change event associated with the USB device for improving GPU performance. The usage change event can be a disconnect event of the USB device, a power renegotiation event between the USB device and the GPU, or any other suitable usage change event.
