Intel® VTune™ Amplifier XE and Intel® VTune™ Amplifier for Systems Help
Frequency calculated using CPU unhalted clockcycles. It is a software frequency showing the ratio of clockticks per time. When the CPU is fully loaded, the metric indicates the CPU frequency. If the CPU is not fully loaded, it may indicate an average CPU load over time. The smaller the sampling interval is, the closer the metric is to the real HW frequency.
