Technically, G3 and G4 aren't the names of the chips. a G3 is a 750, G4 is
74x0. (Supposedly the G5 is going to be 8500)
One theory is that the Nubus Power Macs (61xx, 71xx, 81xx, 91xx) are
considered to be G1 (Generation 1), while the Pre-G3 PCI machines are
considered to be G2.
The other theory is that 601 based PPCs are G1, while 603/604 based PPCs are
G2.
I tend to go with the first one, as the different generations are well
defined. (Nubus vs. PCI) While with the second one, you've got some
weirdness, such as the 7500/7600 issue. They are basically the same
computer, except that one has a 601, the other a 604. If you go by the
second theory, a 7500 is G1, and a 7600 is G2, and putting a 604 in a 7500
would change it from a G1 to a G2.
Either way, the 68k doesn't come into the equation. After all, they are
Generation 3 and 4 Power Macs, not Generation 3 and 4 Macs.
That's my cent and a half.
(Who knows, maybe Apple decided that G3 just sounded cool and went with it.
:) )
