While Intel produces most of the chips for IBM compatible personal computers, Motorola produces the lion's share of the chips for Apple and Macintosh computers. Fortunately for Apple users, chip choices are not as confusing. G3 and G4 chips are the two fastest on the market right now. As earlier mentioned, an important second feature impacting processor chips is the speed of the processor's internal clock. Megahertz usually range from 25 to 800, with faster chips being introduced everyday.
Clock speeds are very easy to understand.
The higher the megahertz, the faster the computing speed. A slow computer will make you wait while a screen redraws or while it computes data. This is usually only a matter of a few seconds of waiting time. However, if you use your computer for several hours each day, those few seconds of waiting time can become frustrating. One choice to speed up your computer is to upgrade the existing processor chip of your computer, but this is usually fairly complicated and expensive.
