 Redefine HD Gaming

  • Advanced Memory
    GDDR5 provides twice the data per pin of GDDR3 memory at the same clock speeds.
     
  • 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 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) capabilities1, 2.
     
  • Accelerated Video Transcoding (AVT)
    With ATI Stream technology, owners of ATI Radeon™ HD 4770 GPUs can help accelerate the conversion of standard and HD video into multiple formats for use on differing consumer electronics devices. The ATI Video Converter, designed to enable GPU transcoding of HD video streams, is currently available.
