Graphics Support
ATI Radeon X850 XT
The Radeon X850 XT graphics processor provides a significant step up in graphics processing horsepower. Featuring a 16-pixel pipeline architecture and a large 256 MB DDR SDRAM frame buffer the performance metrics delivered by the X850 XT are impressive; memory bandwidth is 34.6 GB per second, over 700 million vertices and over 8 billion textured pixels per second. This advanced graphics card also includes SMARTSHADER HD, the latest in graphics programmability allowing users to experience movie-quality effects in 3D games and pro applications. The Radeon X850 XT occupies a single slot and can support a single 30-inch Apple Cinema HD Display on the DVI port. The second port on the Radeon X850 XT is an Apple Display Connector (ADC port) for direct connection of Apple flat panel displays with ADC connectors.
NVIDIA GeForce 6800 GT DDL
The groundbreaking NVIDIA GeForce 6800 graphics processor also features a 16-pixel pipeline architecture and support for the world's fastest GDDR3 memory to raise the bar for 3D graphics performance. The specifications for the GeForce 6800 GT DDL include memory bandwidth of 32GB per second throughput, 525 million vertices and 5.6 billion textured pixels per second. The card features NVIDIA's industry leading CineFX 3.0 technology allowing incredible special effects to be processed in real-time.
The GeForce 6800 GT GPU is built on an AGP 8X board and includes 256MB of GDDR3 memory for use in the most demanding graphics applications. The GeForce 6800 GT DDL card supports the DVI standard dual link digital signal specification on each of the two DVI ports that are included. Dual link capability is required to drive the 30-inch Apple Cinema HD display and the GeForce 6800 GT DDL can drive two of them. The combination of a GeForce 6800 GT DDL with a dual processor Power Mac G5 driving two 30-inch Apple Cinema HD Displays is the definitive tool for the creative professional. Special note on the NVIDIA GeForce 6800 GT DDL: due to larger size of this advanced graphics card, the available PCI or PCI-X slots will be reduced to two slots from three.
Support for ADC, DVI and VGA
All but the ATI Radeon X850 XT graphics card option comes standard with two DVI ports. The Radeon X850 XT features a DVI and an ADC port. VGA based monitors attach to the DVI port via the included DVI to VGA adapter provided with your Power Mac G5 system. The ATI Radeon 9650 and the Radeon X850 XT feature support for one 30-inch Apple Cinema HD Display. The GeForce 6800 GT DDL features two dual-link DVI ports to support two 30-inch Apple Cinema HD's. ADC displays can be attached to any DVI port using an optional (sold separately) Apple DVI to ADC adapter.
Dual Display Modes
Each card offers built-in dual display support in two useful modes. Extended Desktop mode allows users to work on two monitors at once for increased desktop real-estate (and increased productivity). Video mirroring is useful when presenting, so you can see the same image on a projector that you're seeing on your Apple display. Simply attach two monitors and the Mac OS will recognize your display. Use the Displays System Preference to configure your monitors in either extended desktop or mirrored desktop modes.
Dual Apple Flat Panel Displays
Attach multiple Apple flat panels with DVI connectors to your Power Mac G5 graphics card directly. If you have an Apple flat panel with an ADC connector the optional Apple DVI to ADC adapter is required (sold separately). This adapter allows you to use the DVI port on your graphics card to drive an ADC monitor. Offering more than just a physical connection between a DVI port and a digital ADC monitor, it's been designed to maintain the digital integrity of the video signal to give you the ultimate pure digital experience. It features active components that regenerate both the digital graphics signal and the USB signal coming from the computer. The Apple DVI to ADC Adapter comes with a power supply, power cord and a 2-meter DVI/USB cable.
