What determines cpu frequency

OK, the thread title sounds pretty ignorant I admit. I'm just curious about what makes my cpu raise it's frequency from 1600 to 3400. As I watch it on my system monitor sometimes it will jump up to 3400 under just 8-10% load and other times load can be as high as 20% and it will remain at 1600.

I realize that my monitor is actually taking snapshots, in my case at 2 second intervals, so there may be a lot happening that I don't see. Nonetheless, this got my curiosity up.

Is load the determining factor in cpu frequency? Or does something else come into play here?

Based on what you are saying you have an Intel® processor. The speed of 1600MHz is the speed that you would see when Intel SpeedStep® is active. This means that you dont have anything going on at that moment that demands processing performance. So to save power it drops it down to a lower speed to save you money.

The model # of processor would be helpful in explaining if the 3400 is the higher or the speed with turbo boost or even if you have turbo boost on your processor.
