Power Mac G4
Buckle up—the Power Mac G4 is here. It features the revolutionary
PowerPC G4 with Velocity Engine, which crunches multimedia data at
blazing-fast speeds. The Velocity Engine uses true independent vector
processing—a technology originally developed for use in scientific
supercomputers. It gives you the power you need to create and
manipulate even the most complex graphics files. The result is
unprecedented productivity for creative professionals—in the arts
as well as the sciences.

Apple designed the new Power Mac G4 for creative professionals who use computers as the
pivotal tool of their trade, setting the pace of their work, their productivity, even their success.
With its Pentium-crushing speed and convention-crushing design, the Power Mac G4 picks up
where the best-selling Power Macintosh G3 left off. It’s simply the fastest desktop computer
ever, easily running up to a stunning 100% to 200% faster than the fastest Pentium III–based
PCs.1 The Power Mac G4 is so powerful that its speed is measured in gigaflops, or billions of
floating-point operations per second, just like supercomputers.
At the heart of this system is the brand-new PowerPC G4 with Velocity Engine. Using vector
processing, the PowerPC G4 brings supercomputer performance to the desktop for the first
time. The Velocity Engine moves vector and multimedia data at superefficient speeds—it can
process data in 128-bit chunks, instead of the smaller 32-bit or 64-bit chunks used in traditional
processors. System performance is further enhanced through the use of an all-new, superfast
system bus and 1 megabyte of backside cache.
Expansion is this computer’s particular talent. It accommodates more than 100 gigabytes of
hard disk storage and up to 1.5 gigabytes of SDRAM.2 USB and FireWire ports let you connect to
high-bandwidth peripherals such as printers, digital video cameras, hard disk drives, and more.
Three 64-bit PCI slots, a feature that until recently was available only in high-end workstations,
support a wide variety of expansion cards. Choose Apple’s Final Cut Pro video editing software
for flexible, highly productive video editing, compositing, and special effects.
When you’re ready, get unwired with AirPort, Apple’s new high-speed wireless local area
network option.3 AirPort gives you the freedom to surf the Internet without cables, additional
phone lines, or complicated networking hardware. Just install the AirPort wireless networking
card, connect to an AirPort wireless network, and start surfing from your business, classroom,
or any room in your home.
For all those who consider their desktop system a tool for expressing their creative abilities,
there’s finally a computer that can keep up with everything their minds can imagine—as quickly
as they can imagine it. Power Mac G4.
