Technology Overview 17 Power Mac G5 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 filters. • 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 filter test, an HDV green screen matte, and a particle e∂ects test.

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.

Motion tests included a mix of particle e∂ects, green screen compositing, and filter e∂ects. Halo 1.5.2 was tested using the Time Demo benchmark with advanced pixel shaders.
