Technology Overview

Power Mac G5

• All Power Mac G5 cards support two displays: one 20- or 23-inch Apple Cinema Display

and one 30-inch Apple Cinema HD Display. If you want to connect your Power Mac

G5 to two 30-inch Apple Cinema HD Displays—or use stereo 3D goggles—choose the

workstation-class NVIDIA Quadro FX 4500.

• If you plan to install as many as three PCI Express cards in your Power Mac G5, you’ll

want to consider cards that occupy a single slot.

Graphics performance

Each of the graphics card options available for the new Power Mac G5 provides

excellent support for 2D and 3D operations in applications such as Motion and in

games such as Halo.

Motion graphics. Motion, Apple’s motion graphics design application, leverages

the graphics processor to animate e∂ ects onscreen in real time. The test protocol

measured the uncached playback, cached playback, and export to QuickTime of

three projects: a ﬁ lter test, an HDV green screen matte, and a particle e∂ ects test.

3D gaming. 3D gaming involves realistic visualizations and rapid movements that

require maximum processor performance and top-of-the-line graphics capabilities—

all with more complexity and better texturing than ever before. Frame rates were

measured using the game Halo, one of the most popular gaming titles on the market,

which leverages the programmability features of the graphics card.

* Testing conducted by Apple in September 2005 using preproduction 2.5GHz Power Mac G5 Quad units. Motion tests included a

mix of particle e∂ ects, green screen compositing, and ﬁ lter e∂ ects. Halo 1.5.2 was tested using the Time Demo benchmark with

advanced pixel shaders.

Core Image in Mac OS X

Built into Mac OS X, Core Image is an

advanced image-processing technology

that leverages the graphics processor for

blistering-fast rendering performance.

E∂ ects and transitions can be expressed

with a few lines of code. Core Image handles

the rest, optimizing the path to the graphics

processor. The result is real-time response

as you select and apply ﬁ lters.
