    Without a full explanation, advertising turboboost could be misleading, but the full explanation will likely confuse people (Apple wants buying a computer to be simple).

    TurboBoost only activates when the power use, number of cores in use, and core temperature is low enough. It is designed to provide a boost to single threaded applications running on multicore CPUs. If you have a fully multithreaded video render running, Turboboost likely won't be able to activate since both cores will be in use, the temperature will be high, and the power use will be high. Otherwise they would just run the CPUs at 3.33GHz all the time and advertise them that way.

    Where it really comes in handy is for quad core mobile CPUs that are clocked at ~1.6GHz. That's low enough to give a performance hit on single threaded applications if there was no TurboBoost.
