Designed specifically for users of Apple's Power Mac desktop systems (Mac OS X version 10.2.5 or higher), the ATI Technologies Radeon 9800 Pro Mac Edition graphics card takes visual realism and performance for games and 3D animation to exciting new heights. The Radeon 9800 Pro Mac Edition offers full OpenGL support and full floating-point architecture to deliver all the performance and power of the standard Radeon 9800 Pro, with the added feature of ATI's VersaVision display rotation, a versatile dual display configurable for either landscape or portrait display. With 8 parallel rendering pipelines, a 256-bit memory interface, and 128 MB double-data-rate (DDR) memory, the card is capable of executing up to 8.4 billion instructions per second and delivering an astounding 21 GB per second of memory bandwidth. The graphics board's display flexibility supports multiple displays through its VGA, DVI, and S-video outputs.
SmoothVision anti-aliasing technology enhances image quality using programmable multi-sampling methods to post-process graphics before they are actually displayed. SmartShader makes both the geometry- and pixel-processing stages more programmable than ever so developers can easily create new graphics effects while maintaining high performance. Finally, Hyper Z makes Z-buffer bandwidth usage more efficient by decreasing the amount of information sent to the frame buffer.
VersaVision lets you rotate your display while maintaining the full feature set of other ATI 2D and 3D technologies. ATI's hardware-accelerated display rotation and scaling technology allows for rotation left or right by 90 degrees, or you can flip it upside down for a full 180-degree rotation. Relative Rotation allows you to rotate the contents of your display. The card maintains full 3D support regardless of your selected rotation. (A revert button undoes all changes and sets everything to the original state or last known good setting.)
Note: Radeon 9800 Pro Mac Edition only displays 3D graphics in thousands and millions of colors. When you set your display to 256 colors, this will affect Finder, OpenGL, Quartz Extreme, and QuickTime acceleration.
