You're right back in the PPC days, Apple was marketing their computers as faster then Intel chips and to a degree that was the case. G3s had an edge on the then current Intel chips, but that advantage quickly evaporated. By the time the G5 came out, it was too little too late. In fact Apple was going to Intel when IBM convinced them that the G5 PPC chip was better. Sadly, in the long run IBM was unable to roll out a 3GHz CPU (as they had promised Apple) and was unable to get a low powered model for laptops. Apple gave up and transitioned to Intel which was a great move and perhaps over due.
