This video shows one of the GPU tuning tools (PVRTune) used during A80 development. To run the tests, an A80T tablet is hooked up to a host computer running PVRTune. A tester can then operate different use cases on the tablet (scrolling through the GUI, playing games, etc) while seeing how GPU load is affected on the host computer’s PVRTune display window. In this video, we see how the GPU’s 3D engine is loaded while scrolling through Android’s stock GUI. When performance bottlenecks are spotted, this tool can help engineers better distinguish CPU/GPU root causes, increasing debugging efficiency.
