(3) The fourth generation of IBM's CMOS-based mainframes (Parallel Enterprise Servers), introduced in 1997. See IBM mainframes and Parallel Enterprise Server.

(4) An earlier series of Mac desktops and PowerBook portables that used the 32-bit G4 chip based on Motorola's PowerPC 7400. Introduced in 1999, G4 models were the successor to the G3 series and supported 2GB of RAM, 64-bit PCI slots and 4x AGP. The G4 CPU included the "Velocity Engine," which provided one gigaflops of floating point processing. See G5, G3 and Apple.
