This is clear in the MacBench 5.0 FPU and G4TimeDemo tests. G4TimeDemo uses the AltiVec engine in a 3D game environment and the G4 beats the G3 by 40-80 percent. The PowerPC G4 CPU is a terrific CPU for those applications that use floating point calculations, especially if they are optimized to use the AltiVec engine. PowerLogix's PowerForce G4 and G4 ZIF will transform your older Mac into a performer equivalent to the new Apple supercomputers. The design, workmanship and claimed compatibility are outstanding.
Installation is very easy.
Setup is not too difficult. The software is outstanding. The manual has all the information needed to walk one through all the steps. With the extra steps required for the G4, there would be less of an opportunity for confusion with a separate G4-specific manual. The principal feature of PowerLogix CPU upgrade cards has been their ability to be optimized for the greatest speed in any computer.
