Product Description

Savage3DTM brings high performance 3D graphics to the mainstream PC by integrating 2D acceleration, MPEG-2 video acceleration, and leading edge 3D performance into a cost effective package. Savage3D provides the solution for the high performance consumer, corporate desktop user and entry level professional.

Featuring a high performance 128-bit engine, Savage3D delivers a new single cycle architecture which provides leading edge performance along with the highest image quality.

The single cycle trilinear filtering enables the highest 3D graphics performance along with stunning image quality. Savage3D is the first 3D accelerator to utilize S3TC, which was endorsed by Microsoft as the standard compression technique in DirectX. The high quality texture compression enables 6X the amount of texture storage and AGP bus bandwidth. Savage3D produces the most vivid and realistic images through its true color rendering, which enables the use of 16 million colors vs. the traditional 64K. Savage3D architecture is optimized for full AGP 2X implementations and high performance AGP Texturing.

New Triangle Setup Engine
The advanced triangle setup engine provides industry-leading 3D performance for realistic user experience in games and other interactive 3D applications. The new 3D engine is designed for AGP texturing from system memory and provides peak performance with many 3D features enabled, such as trilinear filtering, specular and diffuse shading, perspective correction, and fogging. This powerful 3D accelerator moves the market to support more complex games and interactive 3D applications.

128-bit 2D Graphics Engine
The state of the art 128-bit 2D graphics engine delivers high speed 2D acceleration for productivity applications and wins benchmarks for desktop PCs. This full featured 2D engine provides acceleration in many color depths.

DVD Playback and Video Conferencing
Savage3D provides the ideal architecture for high quality MPEG-2 playback for interactive DVD applications and video conferencing. The video accelerator off loads the CPU by performing the planar to packed format conversion and motion compensation tasks. The enhanced scaling algorithm delivers incredible full screen video playback. The multiple video windows and image mirroring provides the ideal solution for video conferencing. The 60MHz VIP video port allows low cost connection to industry-standard MPEG-2 decoders and video digitizers.

S3 Streams Processor Technology
The proprietary S3 streams processor technology provides stretching, filtering and YUV color space conversion required for full screen video playback with both software CODECs and hardware MPEG sources. It allows simultaneous display of graphics and video of different color depths as well as vertical interpolation and color controls for high quality video playback.

TV Output Support
The integrated TV out capabilities set new quality standards for flicker reduction, filtered overscan compensation, and NTSC/PAL encoding. The integrated encoder with Macrovision support enables TV outputs of composite or S-video signals, providing flexibility for desktop computers. The programmable 3-tap flicker filter as well as vertical overscan compensation ensure excellent TV output quality.
