GHz is not processing speed. Hz is not a unit of speed or performance, it is a unit of frequency. In this case is refers to the frequency of the clock signal. Which does have an impact on performance but is certainly not the only contributing factor. 2.4GHz is the base frequency and 3.4GHz is maximum frequency with turbo boost. Your actual frequency will be somewhere between those two numbers depending on a number of factors. And if turbo boost is disabled which it usually is by default when you're running on battery power then it will only run at the base frequency, 2.4GHz.
