How can I tell when Turbo Boost is active on my MacBook?

Question

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.

Answer 1

there's 2 utilities that could provide that info,

• one from Intel called MacCPUID (http://software.intel.com/en-us/articles/download-maccpuid/)

• other called CPU-X (http://netkas.org/?p=72) rather outdated

Hope this helps.
