The G4 AGP introduced a number of performance improvements, including AGP-based graphics, AirPort compatibility, a faster memory bus, DVD-ROM or RAM standard, an internal FireWire port, 2 separate USB buses for a combined 24 Mbs, a 2X (133 Mhz) AGP slot, and up to 1.5 GB of RAM. The G4 AGP also introduced the new professional color, "graphite."
Edit: Apple var sin vana trogen redan då - (Om Yikes!) Originally, the MPC 7400 chip had been planned to debut in the G4 AGP model, but Apple was not able to get the new machine ready in time. The G4 PCI had been in the works in case of such an event, and allowed Apple to ship 7400-equipt machines while they worked out the final bugs of the G4 AGP.
