    摘要: A method includes executing a workload on a graphics (GFX) core in a first mode the GFX core comprising a plurality of Subslices wherein each of the plurality of Subslices dissipates power. The method further includes calculating a number of clock cycles, Tfirst mode, required for the GFX core to perform the workload in the first mode during a first decision window comprising a plurality of clock cycles and calculating a number of clock cycles, Tsecond mode, required for the GFX core to perform the workload in a second mode during the first decision window wherein the second mode comprises executing the workload with fewer of the plurality of Subslices receiving power than when executing the workload in the first mode. It is then determined, based in part upon Tfirst mode and Tsecond mode, if an energy savings is possible by transitioning the GFX core to the second mode.

    摘要: According to some embodiments, performance bottlenecks that arise in particular resources within a graphic processor unit may be alleviated by dynamically rebalancing workloads among the resources, with the goal of removing the current performance bottleneck, while at the same time maintaining power dissipation within a currently allocated power budget. In some embodiments this may be achieved by defining a separate clock domain for each of the plurality of graphics processor resources whose performance may then be rebalanced.
