I am looking at getting a computer off of ebay, and I would like to know what the diffrences are between a PowerMac G3 and G4 machines. They are both 400mhz. Is there FSB diffrence or what?
The G4 processor has something called an altivec engine.
It basically greatly speeds up applications that support altivec and makes them run faster. Some applications require altivec (iDVD & iMovie 4 I believe) so a G3 is not a wise decision IMO.
A 1Ghz G3 is slower than a 800Mhz G4 at certain tasks...
