I was bored today and discovered something about G4 speeds. The last few major revisions of the G4 have been clocked at: 500, 667, 733, 867, 1000, 1250. Now if you take 500 and add 20% it is 600. Do the same to 600 and it is 720. Using this method it comes out to: 500, 600, 720, 864, 1036, 1244. After 600 it seems to be fairly close to actual processor speeds. If you continue the sequence then the next two speeds in the series are about 1.5Ghz and 1.8Ghz. Just an interesting discovery I thought I would share.
