Redefine HD Gaming

  • TeraScaleGraphics Engine
    • The new TeraScale graphics engine features over one teraFLOPS, nearly one billion transistors and 800 stream processors so you can enjoy the high resolutions and fast frame rates previously only available with dual-card systems.

 

  • 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.
  • Power to Spare
    • This GPU has the brute processing power needed for physics, artificial intelligence, stream computing and ray tracing calculations.

Go Beyond HD Video

 

  • 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.** Full 1080p files can be converted to H.264 and MPEG-2 up to 1.8x faster than real-time
  • Upscale Beyond 1080p
    • Watch the hottest Blu-ray movies or other HD content at full 1080p display resolution and beyond.
  • 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.

 

Break-through Efficiency – Proof Points
