Product Description

The Power Mac G4 is the
first Power Mac computer
based on the PowerPC G4
processor. Some
configurations also include
support for wireless
networking, dual-channel
USB, Gigabit Ethernet, dual
processing, digital audio,
and a wake/sleep power
management feature.

Basics Identifying Versions of the Power Mac G4 - 2

Identifying Versions of the Power Mac G4

There are six models of
Power Mac G4 computers:
AGP Graphics, PCI Graphics,
Gigabit Ethernet, Digital
Audio, QuickSilver, and
QuickSilver 2002.

Power Mac G4 (QuickSilver
and QuickSilver 2002)
computers are easy to
identify. Unlike other Power
Mac G4 models, these models
have a silver-colored case.
They also have a recessed
speaker on the front panel.

Basics New Technologies - 3

To identify the other Power
Mac G4 models, check the
I/O panel at the back of the
computer. The sound ports
align horizontally in the
lower half of the I/O panel
on PCI Graphics models and
vertically on AGP Graphics/
Gigabit Ethernet models. On
Digital Audio models, the
sound ports are in the upper
half of the I/O panel. In
addition, Digital Audio
models include four
expansion slots, instead of
three slots on PCI/AGP
Graphics/Gigabit Ethernet
models.

To further distinguish
Gigabit Ethernet models
from AGP Graphics models,
check the logic boards. AGP
Graphics boards include an
internal FireWire connector
at J9; Gigabit Ethernet
boards do not include the
connector.

New Technologies

While the Power Mac G4
family of computers all use
the innovative PowerPC G4
processor, they also include
a range of other new hard­ware and architectures. For
information on the latest
technolgies, check the Apple
Knowledge Base.
