In one embodiment execution units, graphics cores, or graphics sub-cores can be dynamically scaled across a frame of graphics operations. Available execution units within each graphics core may be scaled using utilization metrics such as the current utilization rate of the execution units and the submission of new draw calls. In one embodiment, one of more of the sub-cores within each graphics core may be enable or disabled based on current or past utilization of the sub-cores based on a set of current graphics operations.
