ATI RAGE PRO TURBO™

Workstation Class / Arcade Level 3D Accelerator

First graphics accelerator to support AGP 2X (133MHz) mode with Sideband Addressing and AGP Texturing (Execute mode) to realize all the benefits of AGP
Superior 3D performance achieved through a floating point setup engine rated at 1.2 million triangles/sec
100MHz SGRAM support for maximum 2D and 3D performance
Integrated 230MHz DAC allows 85Hz refresh at 1600x1200 resolutions
Integrates superior video features, including filtered scaling of 720 pixel DVD content and MPEG-2 motion compensation for software DVD

OVERVIEW

The ATI RAGE PRO TURBO is a highly integrated 64 bit graphics accelerator with superior support for 3D and motion video, making it ideal for multimedia PCs and workstations.

ATI RAGE PRO TURBO incorporates comprehensive support for Intel’s Accelerated Graphics Port (AGP) including 1X or 2X mode and Sideband Addressing. RAGE PRO TURBO supports AGP Texturing (Execute mode), which offers superior performance to the Local Texturing (DMA mode) used in competing solutions.

The RAGE PRO TURBO delivers superior 3D acceleration and comprehensive 3D support including support for true color (32bpp) rendering, a triangle set-up engine, single-pass trilinear filtering, six perspectively correct texturing modes, video texturing, Gouraud and specular shading, texture compositing and a host of other 3D special effects.

The RAGE PRO TURBO includes motion video enhancements and TV-out support via the ImpacTV2 companion chip, enabling ‘Broadcast PC’ systems. Multiple options are available for MPEG-2 and DVD support: in software with ATI’s MPEG-2 motion compensation circuitry, or using the ATI-DVD card or module through the ATI Multimedia Channel (AMC).
