Android GPU Inspector (AGI) 可取樣 Arm® MaliTM、Imagination® PowerVRTM 和 Qualcomm® AdrenoTM GPU 的 GPU 效能計數器。您可以使用這項資料,找出應用程式 GPU 用量中的瓶頸。
您在 AGI 設定系統剖析時,可以啟用各個支援的計數器,然後在系統分析器 UI 的 GPU 計數器部分查看結果。
「Capture System Profiler」對話方塊的「GPU」>「Counters」>「Select」(選取) 選項會列出您的 Android 裝置支援計數器的名稱和說明。如要瞭解如何設定「Counters」(計數器) 選項,請參閱剖析系統一文。
如要進一步瞭解 GPU 效能計數器,請參閱 GPU 製造商提供的開發人員指南。以下指南包含 GPU 計數器資訊;不過,詳細程度可能會因製造商選擇的發布數量而異:

You can use this data to\nidentify bottlenecks in your app's GPU usage.\n\nYou can enable each supported counter when you\n[configure system profiling](/agi/start#system-profile) in AGI, and then view\nthe results in the\n[GPU counters section](/agi/sys-trace/system-profiler-gui#gpu_counter_tracks)\nof the System Profiler UI.\n\nThe names and descriptions of the supported counters for your Android device are\nlisted in the **GPU \\\u003e Counters \\\u003e Select** option of the **Capture System\nProfiler** dialog. For information about configuring the **Counters** option,\nsee [Profile a system](/agi/start#system-profile).\n\nFor additional details about any GPU performance counters, check the developer\nguides that are provided by your GPU manufacturer. The following guides include\nGPU counter information; however, the level of detail can vary based on how much\nthe manufacturer chooses to publish:\n\n- For Arm Mali, see\n [Mali GPU Performance Counters](https://developer.arm.com/ip-products/graphics-and-multimedia/mali-gpus/mali-performance-counters)\n in the Arm Developer guide.\n\n- For Imagination PowerVR, see the\n [PVRTune Counter List and Description](https://cdn.imgtec.com/sdk-documentation/PVRTune.Counter%20List%20and%20Description.pdf)\n guide.\n\n- For Qualcomm Adreno, see the\n [Adreno GPU guide](https://developer.qualcomm.com/sites/default/files/docs/adreno-gpu/snapdragon-game-toolkit/learn_guides.html)."]]
