I belive you are wrong about this. The 'Hammer' family are based on AMD's extension to the x86 architecture so-called x86-64. This is not a pure a RISC design by virtue of the fact it must be backwardly compatible with x86. Athlons and Pentiums are CISC/RISC hybrids they integrate the best features of both design philosophies.It's already a known fact that the Sledgehammer chip is a true 64 bit RISC processor, much like the G3.
The game cube does not use a G4, it uses a custom PPC chip called Gekko."establish a dedicated Mac chip factory, like the G4 factory they built for Nintendo "
