1. A graphics processing unit (GPU) comprising:
a divider;
a first set of circuitry coupled to the divider and configured to receive from the divider a first clock signal having a first frequency;
a second set of circuitry coupled to the divider and configured to receive from the divider a second clock signal having a second frequency; and
a controller configured to selectively control the first frequency independently of the second clock signal based at least in part on respective workloads associated with the first set of circuitry and with the second set of circuitry.
