everyone has been noting that motorola's new chips will top out at 1.33GHz. remember that the 1.42 GHz G4 chips in the old powermacs were basically 1 GHz G4s from motorola, overclocked by apple. so the fastest 'old' G4 was a 1GHz chip, overclocked to 142% of the original speeds. by extrapolation, if apple overclocks these new 1.33GHz G4s by the same amount, we will see G4 chips at 1.9GHz. although these overclocked chips will be hotter than the original 1.33ghz chips, remember that the new G4s are significantly cooler than the previous generation. this may mean that such high speed overclocked chips will run at the same temperature as the current 1GHz G4s in the powerbooks. so we may end up with 1.9GHz G4 powerbooks. or, at the very least, something better than 1.33GHz. this sounds like a good reason for apple to continue it's partnership with motorola (at least, until the G5 and it's supporting technologies have been engineered into a laptop). so the imacs and powerbooks can have one more upgrade cycle on the G4, and be fast, too. what do you think?
