ATI Radeon HD 4800 Series – Key Features
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.
DirectX® 10.1 - Play today while preparing for tomorrow with state-of-the-art DirectX 10.1 graphics capabilities.
ATI CrossFireX™ Technology - ATI CrossFireX™ technology with up to quad GPU support offers superior scalability so your system is ready to level up when you are.
PCI Express 2.0 - Support for PCI Express 2.0 will prepare you for bandwidth-hungry games and 3D applications.
Unified Video Decoder 2 (UVD 2) - UVD 2 frees up your CPU for other tasks so you get The Ultimate Visual Experience™ for even the most processing-intensive content, including VC-1, H.264 and now MPEG-2. Also, take full advantage of Blu-ray functionality with dual-stream, picture in picture (PIP) capabilities.
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
Upscale Beyond 1080p - Watch the hottest Blu-ray movies or other HD content at full 1080p display resolution and beyond.1
Enhanced DVD Upscaling - Watch standard DVD movies in near high-definition quality with DVD upscaling. The GPU uses post processing algorithms to enhance standard and low resolution videos and movies on your HD display.
Dynamic Contrast - Dynamic Contrast automatically adjusts the contrast and brightness during scenes to consistently deliver a crisp, vibrant picture.
HDMI - Enjoy the latest audio technologies using HDMI with 7.1 digital surround sound support. Also, xvYCC support allows the user to enjoy a wider range of color when connected to a capable HDTV.
Dynamic Power Management - ATI Radeon HD 4800 Series graphics cards deliver high performance when needed and conserve power when the demand on the graphics processor is low.
More Performance Per Watt - ATI Radeon HD 4800 series delivers up to 2x the performance per watt of AMD’s previous generation GPUs.
1 HD capable monitor required 2 The ATI Radeon HD 4800 Series GPUs can upscale video display to 2560x1600 on dual-link monitors which is almost twice the display resolution of 1080p displays. 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.).
