Android GPU Inspector (AGI) can sample GPU performance counters from Arm® Mali™, Imagination® PowerVR™, and Qualcomm® Adreno™ GPUs. You can use this data to identify bottlenecks in your app's GPU usage.

You can enable each supported counter when you[configure system profiling](https://developer.android.com/agi/start#system-profile)in AGI, and then view the results in the[GPU counters section](https://developer.android.com/agi/sys-trace/system-profiler-gui#gpu_counter_tracks)of the System Profiler UI.

The names and descriptions of the supported counters for your Android device are listed in the**GPU \> Counters \> Select** option of the**Capture System Profiler** dialog. For information about configuring the**Counters** option, see[Profile a system](https://developer.android.com/agi/start#system-profile).

For additional details about any GPU performance counters, check the developer guides that are provided by your GPU manufacturer. The following guides include GPU counter information; however, the level of detail can vary based on how much the manufacturer chooses to publish:

- For Arm Mali, see[Mali GPU Performance Counters](https://developer.arm.com/ip-products/graphics-and-multimedia/mali-gpus/mali-performance-counters)in the Arm Developer guide.

- For Imagination PowerVR, see the[PVRTune Counter List and Description](https://cdn.imgtec.com/sdk-documentation/PVRTune.Counter%20List%20and%20Description.pdf)guide.

- For Qualcomm Adreno, see the[Adreno GPU guide](https://developer.qualcomm.com/sites/default/files/docs/adreno-gpu/snapdragon-game-toolkit/learn_guides.html).
