It's Motorola's "Generation" for the different CPU models.

Not Motorola's. The "G" does stand for "Generation", but that's Apple's branding.

The PPC 601 and 603 (IBM) series could be considered the "G1" and the 604 series (IBM again) are "G2". The 750xx (IBM) are the "G3" processors, 74xx (Motorola) are the G4 processors, and the 970xx processors (IBM) are G5.
