Included on this page:
The 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:
Rapid Pixel and Texel Rendering Technology to deliver sharp images, fast rendering, smooth motion and awesome detail.
Dynamic Video Memory Technology to allocate graphics memory as needed to balance memory usage among the operating system, applications, and graphics.
Zone Rendering Technology for drawing 3D scenes that optimize performance between graphics and system functions.
Intelligent Memory Management Technology to optimize both graphics and system performance with shared system memory.
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.
