Is there any way of knowing when the Ivy Bridge Turbo Boost is kicking in?

[Jobsian]

2012 11" Ultimate here, I've only had one instance when it became really hot and the fan noticeably loud and that was when I caned the CPU by opening multiple Youtube vids (31 of them) in either 1080p or 720p.

However despite the heat and sound it still performed flawlessly (no skipping), this 2.0GHz i7 is an animal.

I've had no heat/fan issues since as I've been browsing normally however I'm wondering if I had activated the Turbo Boost. Is there any way I can find out in realtime if the CPU is turbo-ing and is it a graded increase or does it go straight to 3.2GHz?

Istat?

 

[travis64]

you have to hold the turbo button

you have to hold the turbo button

That was painless, straight into dashboard, many thanks (for both suggestions!), should hopefully be able to post impressions

Ok I have iStat Pro, it shows the CPU load %, fan RPM etc but I can't find the clock speed, is that available to see?

Anyone have an answer to this?

Turbo is not working in Windows with the Ivy Bridge i7s in the 2012 MBAs.

maybe with sysctl hw.cpufrequency in the Terminal

I believe I read in the Ars review of the Air that the only way to tell was with an Intel tool that only works in Windows.
