Why Do Some Cores in Intel® Core™ Processor Have Lower Frequencies Than Other Cores ?

Environment

Cinebench Multicore

BUILT IN - ARTICLE INTRO SECOND COMPONENT
Summary

Explains why all the cores are running very near the same frequency, with maybe a few running higher.

Description

When running a stress test such as Cinebenc, a few cores run at a low frequency with no power or thermal limits being hit.

Resolution

The clock speed and frequency of the cores will depend on the system and workload. While executing code, Enhanced Intel® SpeedStep Technology and Intel® Speed Shift technology optimize the processor's IA core frequency and voltage based on workload.
