Features and Benefits

TeraScale Graphics Engine - The new TeraScale graphics engine features up to 1.2 teraFLOPS, nearly one billion transistors and up to 800 stream processors so you can enjoy the high resolutions and fast frame rates previously only available with dual-card systems.
Advanced Memory - GDDR5 memory provides twice the bandwidth per pin of GDDR3.
Enhanced Anti-Aliasing & Anisotropic Filtering- High performance anisotropic filtering and 24x custom filter anti-aliasing (CFAA) smooth jagged edges and create true-to-life graphics, for everything from grass to facial features.
Accelerated Video Transcoding (AVT) - AVT allows you to convert videos to H.264 and MPEG-2 formats up to 19x faster than when using a just CPU.3 Full 1080p files can be converted to H.264 and MPEG-2 up to 1.8x faster than real-time.³
Dynamic Contrast - Dynamic Contrast automatically adjusts the contrast and brightness during scenes to consistently deliver a crisp, vibrant picture.

Support and Drivers

1 HD capable monitor required
2 Blu-ray drive required
3 This may vary depending on your system configuration and video formats. Using an Intel Core 2 Duo E8500 3.16 GHz based PC, AMD was able to achieve GPU accelerated transcoding speeds up to 19x faster using Cyberlink PowerDirector than when using the same CPU alone with MainConcept encoder in Adobe Premiere CS3. Using the same system, full 1080p files were converted 1.8x faster than real-time.

ATI Radeon™ HD graphics chips have numerous features integrated into the processor itself (e.g., HDCP, HDMI, etc.). Third parties manufacturing products based on, or incorporating ATI Radeon HD graphics chips, may choose to enable some or all of these features. If a particular feature is important to you, please inquire of the manufacturer if a particular product supports this feature. In addition, some features or technologies may require you to purchase additional components in order to make full use of them (e.g. a Blu-Ray or HD-DVD drive, HDCP-ready monitor, etc.).
