The processor in the Power Mac G4 Cube is a PowerPC G4 microprocessor running at a clock frequency of 450 or 500 MHz.
The PowerPC G4 microprocessor uses a pipelined system bus that is more efficient than the system bus on the PowerPC G3 microprocessors. The bus design, called MaxBus, allows for much greater efficiency of bus utilization than was possible with the previous design.
Features of the PowerPC G4 include:
