Note
This analysis type is available as part of energy analysis. Energy analysis is provided by the Intel® VTune™ Amplifier for Systems only. Energy analysis collection is supported for target Android*, Windows* or Linux* devices.
Use the CPU Frequency analysis to explore the processor frequency behavior: track frequency changes in the timeline and identify cores with the most time spent in the high frequency modes. Typically, spending more time in low frequency modes provides greater power savings.
CPU Frequency Analysis Results
VTune Amplifier displays the results of the CPU Frequency analysis in the Platform Power Analysis viewpoint with the following windows. Some windows may or may not appear, depending on the data collected:
Summary window displays a summary of the data collected.
Correlate Metrics window displays timelines for C-States per package and core, core frequencies, and kernel and user wakelocks, aligned on the same time scale.
CPU C/P States window displays P-state and frequency data collected per core and over time.
