Product Description

The newest member of S3®'s SavageTM product family, Savage4TM brings high-end graphics performance to the mainstream PC by integrating leading-edge 2D, 3D and DVD video acceleration into a cost effective package. Based on its capabilities, Savage4 is an ideal solution for the consumer, corporate desktop user and entry level professional. The industry's first AGP 4X solution, Savage4 combines AGP 4X with S3's DX6 texture compression (S3TC) to deliver unprecedented 3D performance and image quality for the mainstream desktop PC market. Supported by many of 1999's top 3D games such as Unreal Tournament and Quake III Arena, S3TC enables software developers to use up to 8x the amount of texture storage and AGP bus bandwidth.

High-Performance 3D Accelerator

Featuring a new super-pipelined 128-bit engine, Savage4 utilizes a single cycle architecture that provides high performance along with superior image quality. Several new features enhance the 3D architecture, including single-pass multitexturing, full scene anti-aliasing, anisotropic filtering, an 8-bit stencil buffer and hardware bump mapping. Savage4 also offers the industry's only simultaneous usage of single-pass multitexturing and single-cycle trilinear filtering - enabling stunning image quality without performance loss. Savage4 further enhances image quality with true 32-bit color rendering throughout the 3D pipeline to produce more vivid and realistic images. Savage4's advanced triangle setup engine provides industry leading 3D performance for a realistic user experience in games and other interactive 3D applications. The 3D engine is designed for AGP texturing from system memory or the local frame buffer.

128-bit 2D Graphics Engine

Savage4's advanced 128-bit 2D graphics engine delivers high-speed 2D acceleration for productivity applications. Several enhancements have been made to the 2D architecture to maintain best of class performance and to provide acceleration in all color depths.

DVD Playback and Video Conferencing

Savage4 provides the ideal architecture for high quality MPEG-2 based DVD applications and video conferencing. For DVD playback, Savage4's video accelerator offloads the CPU by performing the planar to packed format conversion and motion compensation tasks, while its enhanced scaling algorithm delivers incredible full-screen video playback. For video conferencing, Savage4's multiple video windows and image mirroring provide an ideal solution. Finally, Savage4's 60 MHz VIP video port allows low cost connection to industry-standard MPEG-2 decoders and video digitizers for applications such as WebTV® and TV tuner designs.

Flat Panel Desktop Monitor Support

Savage4 has the capability of displaying graphics on flat panel desktop monitors using a 24-bit digital interface to an external encoder. Savage4 also supports autoexpansion and centering of all VGA text and graphics modes to ensure that the entire flat panel display will be utilized. All resolutions are supported up to 1280x1024.
