    Actually it was the PPC 601 that was generation 1 and the 603 & 604
    lines made up generation 2. They had the same foundation at the start
    and just diverged like two siblings going off on different paths.

    It appears, searching the motorola site, that the term G2 was first
    used for a processor core based on the 603e (which followed the 603).
    There never was a G1, and the 603 and 604 themselves didn't
    fall into the naming scheme. The 604 line apparently was a dead end.

    The G3/G4/G5 for Mac names is primarily Apple's naming scheme. I talked
    with someone from Apple several years ago and that's what they
    considered for the generational numbering.
