There are several different families of PowerPC chips.
The ones I can think of off-hand (I haven't done much with PPC lately):
* Motorola/IBM 60x / G2/G3/G4 series.
* IBM 970 (Apple's "G5")
* Motorola 82xx (really G2/G3 + peripherals)
* Motorola 860 and variants
* Motorola 85xx
* IBM/AMCC 4xx (401, 405, 440, etc.)
Within each family, there are some similiarities, but sometimes some
significant differences, as between the 405 and 440.
The IBM/AMCC 4xx, especially, have a number of differences even between
different chips with the same number. The 405 and 440 each have a
number of variants with the same CPU core and different integrated
busses and peripherals. I think Motorola does the same thing with
