Window: CPU Frequencies

Use the CPU Frequencies window to analyze the time spent in different frequency modes and frequency transitions and identify cores that consume a lot of power. The CPU Frequencies window is available for the CPU Frequency viewpoint. To open the window, click the sub-tab in the result tab.

The CPU Frequencies window consists of the CPU Frequencies pane and Timeline pane.

Note

Power analysis is provided by the VTune Amplifier for Systems only. To analyze applications on Linux* target systems, run the CPU Sleep States or CPU Frequency analysis types from the VTune Amplifier GUI or CLI installed on the Linux or Windows* host. To analyze applications on Android* devices, use the Intel Energy Profiler (SoCWatch/WuWatch) to run the analysis directly on the device. You can view collected data either in the text-only mode on the device or import and view the data in the VTune Amplifier GUI nstalled on the host system.
