I have one of the core i7 MacBooks, and I'm wondering if there is a way to see when Turbo Boost is active (other than the fact that the laptop gets really hot and the fan kicks on).

I use iStat to monitor CPU activity, but that doesn't show Turbo Boost activity.

The MacCPUID always shows that my CPU is clocked at 2.3 GHZ. But in fact it should change from time to time and go from 1.8GHZ-2.8GHz. Not really helpful. –  gentmatt Dec 28 '12 at 12:38

Check out the Intel Power Widget - It provides info about the processor frequency in GHz and Processor Power in W.

On my Mid 2010 iMac with a core i7 the installer balks, saying "Intel® Power Gadget only supports 2nd generation Intel® Core™ processors and later." –  AllInOne Aug 5 '13 at 23:18
