San Jose, CA--March 24, 1997--ATI Technologies Inc. (Thornhill, Ontario) demonstrated at Intel's Visual Computing Day its next-generation 3D graphics accelerator chip--the 3D RAGE PRO. It is the industry's only accelerator to unleash the full potential of Intel's Accelerated Graphics Port (AGP) and advanced processors such as the Pentium II. The DVD-enabled 3D RAGE PRO, with three times the 3D performance of the previous generation, is the first demonstrated AGP accelerator to support the 2X (133 MHz) mode of AGP, which offers twice the bandwidth of chips limited to the IX (66 MHz) mode.
Designed to take full advantage of the AGP high-speed interface, 3D RAGE PRO features 100-MHz SGRAM, floating-point set-up engine, 4-kbyte texture cache, a host of unique 3D features, 230-MHz DAC, and enhanced MPEG-2 motion compensation. 3D RAGE PRO components and boards are now sampling to major OEMs.
The 3D RAGE PRO supports AGP 2X mode with a peak bandwidth in excess of 500 Mbytes, which is twice the throughput of competitive solutions that are restricted to the AGP 1X mode. PCI graphics devices are limited to 133 Mbytes of peak bandwidth that must be shared with other PCI devices. Unlike competing solutions, the 3D RAGE PRO also supports AGP's pipeline and sideband protocols. These significantly improve the sustained bandwidth that is critical to 3D and video performance. Beta AGP drivers are now available for the 3D RAGE PRO. ATI is working closely with Intel and Microsoft to have software support for the AGP 2X mode available for production in calendar Q3/97.
The 3D RAGE PRO integrates a floating-point set-up engine capable of processing up to 1.2 million triangles per second. Significantly improving the 3D experience, this set-up engine greatly improves the performance of small triangles that add detail to 3D scenes. By off-loading the set-up function from the CPU, the 3D RAGE PRO dramatically improves the performance of the entire 3D pipeline by allowing the CPU to focus on 3D geometry and lighting transformations.
3D RAGE PRO's 64-bit, 100-MHz SGRAM interface delivers 800 Mbytes of low-latency frame buffer bandwidth, which is the highest bandwidth achieved by any mainstream graphics controller.
3D RAGE PRO also features a de-interlacing filter, video on graphics overlay, multi-stream video, color-space conversion, scatter-gather bus-master, planar YUV mode, ATI Multimedia Channel (AMC) video input port, and support for high-quality NTSC & PAL TV-out with the ATI ImpacTV chip.
3D RAGE PRO is available with an integrated 230-MHz DAC that supports 1600x1200 resolution at the 85-Hz refresh rate specified by the European market. Industry-leading 2D performance is provided by 100-MHz SGRAM, faster 2D engine speed, a deeper command FIFO, AGP 2X mode, and optimized drivers, resulting in WinBench 97 scores of over 100 million at 1024x768 in 65,000 colors.
Drivers will be available for all corporate operating systems and APIs, including Windows NT 4.0, Windows NT 5.0, Windows 95, Memphis, OS/2, MacOS, DirectX, OpenGL, Heidi, and QuickDraw3D. This allows support for 3D applications such as SGI's Cosmo Player VRML 2.0 browser, which ATI will bundle with ATI products.
For PC workstations, the 3D RAGE PRO can be configured with WRAM memory and an external 250-MHz DAC that will provide unmatched 2D and 3D performance at high resolutions and color depths. 3D RAGE PRO is the first mainstream part to incorporate edge anti-aliasing, deemed a necessity by CAD users.
The 3D RAGE PRO chip is available in AGP and PCI variants. The AGP 2X mode version supports the AGP 2X mode and a 230-MHz DAC and is packaged in a 256-pin BGA. The AGP 1X mode version is a pin-compatible 256 BGA for cost-sensitive markets, which supports the AGP 1X mode and a 200-MHz DAC. The PCI version is packaged in a 208-pin PQFP, which is also a pin-compatible performance upgrade for ATI's family of 264VT and 3D RAGE chips, offering a fast refresh strategy option for OEM systems. The PCI version incorporates the same performance enhancements and new features as the AGP 3D RAGE PRO version.
