About Interpreting Power Analysis Data

Note

Power analysis is available only with the Intel® VTune™ Amplifier for Systems, part of Intel System Studio. For Linux* platforms based on Intel Xeon® processors, use Power analysis types provided with the VTune Amplifier GUI. On Windows* OS, you may import and view results collected on a Linux platform. For Power analysis on Android* platforms, use the Intel® Energy Profiler tools to analyze power consumption for your system and identify causes of wake-ups that waste energy. To view the power analysis results collected on an Android system, use the VTune Amplifier for Systems graphical interface.

The power analysis types have the following associated predefined viewpoints:

  • CPU Frequency viewpoint to identify time spent in different frequency modes.

  • CPU Sleep States viewpoint to see the time spent in each sleep state and analyze causes of processor wake-ups.
