Geforce 6800 Chipset Features and Specifications
CINEFX 3.0 SHADING ARCHITECTURE • Vertex Shaders - Support for Microsoft DirectX 9.0 Vertex Shader 3.0 - Displacement mapping - Geometry Instancing - Infinite length vertex programs • Pixel Shaders - Support for DirectX 9.0 Pixel Shader 3.0 - Full pixel branching support - Support for Multiple Render Targets(MRTs) - Infinite length pixel programs • Next-Generation Texture Engine - Up to 16 textures per rendering pass - Support for 16-bit floating point format and 32-bit floating point format - Support for non-power of two textures - Support for sRGB texture format for gamma textures - DirectX and S3TC texture compression • Full 128-bit studio-quality floating point precision through the entire rendering pipeline with native hardware support for 32bpp, 64bpp, and 128bpp rendering modes
64-BIT TEXTURE FILTERING AND BLENDING • Full floating point support throughout entire pipeline • Floating point filtering improves the quality of images in motion • Floating point texturing drives new levels of clarity and image detail • Floating point frame buffer blending gives detail to special effects like motion blur and explosions
INTELLISAMPLE 3.0 TECHNOLOGY • Advanced 16x anisotropic filtering • Blistering-fast antialiasing and compression performance • New rotated-grid antialiasing removes jagged edges for incredible edge quality • Support for advanced lossless compression algorithms for color, texture, and z-data at even higher resolutions and frame rates • Fast z-clear • High-resolution compression technology (HCT) increases performance at higher resolutions through advances in compression technology
ULTRASHADOW II TECHNOLOGY • Designed to enhance the performance of shadow-intensive games, like id Software's Doom III
ADVANCED VIDEO AND DISPLAY FUNCTIONALITY • Dedicated on-chip video processor • MPEG video encode and decode • WMV9 decode acceleration • Advanced adaptive de-interlacing • High-quality video scaling and filtering • Dual integrated 400MHz RAMDACs for display resolutions up to and including 2048x1536 at 85Hz. • Dual DVO ports for interfacing to external TMDS transmitters and external TV encoders • Microsoft® Video Mixing Renderer (VMR) supports multiple video windows with full video quality and features in each window • Full NVIDIA® nView™ multi-display technology capability
