Intel(R) extreme graphics

The new integrated graphics core in the Intel® 845G, Intel® 845GL and Intel® 830M chipsets deliver an intense visual experience. Innovative technologies add new levels of both 2D and 3D graphic quality to integrated graphics chipsets: The Extreme Graphics core supports the latest 2D and 3D APIs, delivering real-life environment and character effects. A 256-bit internal path enables up to four textures per pixel on a single pass for super light maps, atmospheric effects, and more realistic surface details. Flexible display capabilities enhance the personal computing experience, offering significant benefits for applications requiring 32bpp and higher display resolution.

Features and Benefits

Feature Benefits
Multi-texture Useful for creating light maps, atmospheric effects, and more
2kx2k texture Enables desktop-size textures
Cube reflection textures Enables environment specular reflections
Render-to-texture Allows auto-generation of texture on the fly
Projected textures Projects textures onto other objects
DOT3 bump-mapping Models realistic surface details
Destination alpha blend Creates effects like force fields, flames, or plasma beams
Point sprites Provides particle systems for atmospheric effects such as snowfall
Per pixel fog Enables depth-cruising or hidden objects
Alpha blended sub-picture support Enables softer effects for captions and subtitles
Anisotropic filtering Provides high quality views of oblique surfaces
Hardware motion compensation Provides high-quality DVD playback
5x2 overlay Delivers smooth scaling of DVD playback
