Power Mac G4

The Power Mac G4 by the numbers.

With software applications becoming bigger and better—and making more demands on your computer’s processor—you could use all the additional horsepower the Power Mac G4 provides. With PowerPC G4 with Velocity Engine speeds up to 500MHz, one megabyte of backside level-2 cache running at half the processor speed, and a 100MHz system bus supporting up to 800-megabytes-per-second data throughput, the Power Mac G4 delivers pulse-pounding performance. And when you’ve completed your projects, shooting those big files across the network is a snap. Because every new Power Mac G4 comes with 10/100BASE-T Ethernet built in.
