I agree with you that the "G" labelling is unfortunate. It's not like there aren't several "G"enerations in each generation, right?
But while some people doesn't seem to like the "G3" mentioned in the same sentense as "A1", they certainly have no problems in proclaiming that "it is faster than the G4 anyway", like "G4" would be one CPU only! Well, the 750GX is indeed a very nice CPU (it will be interesting to see what frequencies will be available for the Pegasos2 BTW ;-)) and it may very well be faster than the old-timers 7451 and 7455 "G4's" for some general usage, but I believe that the Freescale 7447A certainly is up for a serious competition, *both* in performance *and* heat! IMHO, the 7447A is the best PPC CPU of all today (not counting the "G5" platform).
And there is this little "aber" in many peoples reasoning - they are for some reason leaving out the Altivec from the comparisons. The G4 has the Altivec, the G3 doesn't, and that *does* make a difference, even when comparing to the "old-timers" G4's.
