The G5 (970FX) is a derivative of the IBM Power4 server chips.
Many of us were hoping to see either the 970MP dual core processors or a
Power 5 configuaration, but that's looking more unlikely as Apple breaks away from IBM now.
G5's are PPC 970's, which are a version of the POWER4 architecture. POWER5 came out in 2004, after PPC970. Jobs said they weren't happy with the direction that the PPC architecture was going. I doubt these will ever get close to being in a PowerMac.

That was because the Power5-UL was canceled and Apple was "offered" a choice of paying IBM to deliver the Power5-UL or taking IBM development freebie on the Cell.
The Cell required a major rewrite, and if Apple paid for the Power5-UL the would be in the same position of paying for the development of a Power6-UL.
Basically IBM pruned the PowerX-UL from their roadmap, while waving Cell as the next big thing.
