TU-Berlin has setup a testbed to accurately measure GPU power consumption. This testbed is being used to evaluate power reduction techniques on available GPUs. It will also be used to validate the power modeling of GPUSimPow, the GPU power simulator developed within the LPGPU project. Its high bandwidth and high sampling speeds enable it to accurately measure short, sub-ms power events.
The TU-Berlin developed measurement software allows developers to pinpoint power consumption down to the individual kernel.
