Energy Analysis

Use Intel® SoC Watch and
Intel® VTune™
Profiler
 to collect and analyze power and energy consumption metrics. You can collect data on Windows, Linux, or Android systems. Use this data to identify system behaviors that waste energy.

Get Snapshot through
Intel® VTune™
Profiler

In the snapshot view, you can observe package power consumption over time when you run any analysis type in
Intel® VTune™
Profiler
. This option is available when you run
VTune
Profiler
 on Windows, Linux, or Android systems.
  1. On the
    VTune
    Profiler
     welcome screen, click

  4. Select options as necessary.
  5. At the bottom of the analysis type, check
    Analyze power usage
    .
  6. Click
    Start
    () to run the analysis.
When the analysis completes,
VTune
Profiler
 displays package power usage information (collected by Intel® SoC Watch) in the Platform tab.
Track package power usage to see if the CPU is likely to enter a throttling phase. If that happens, you can run a throttling analysis to explore possible causes.
For detailed information about using Intel SoC Watch, see the Energy Analysis User Guide.
