Sapphire HD4770 PCIE 512MB DDR5 VGA DVI-I HDMI 128BIT

Condition: Brand new, USA Warranty
The HD4770 is the first card in its class to use GDDR5 memory. It's based on the first ever GPU built in 40nm process technology. It uses the powerful graphics architectures from the ATI division of AMD, incorporating multi-purpose stream processing units

Redefine HD Gaming

  • Advanced Memory - GDDR5 provides twice the data per pin of GDDR3 memory at the same clock speeds.
  •  Enhanced Anti-Aliasing (AA) & Anisotropic Filtering (AF) - 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
  • Microsoft 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) - Unified Video Decoder 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) - 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
  • 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.

      1 HD capable monitor required
      2 Blu-ray drive required
      3 The ATI Radeon HD 4770 GPU can upscale video display to 2560x1600 on dual-link monitors which is almost twice the display resolution of 1080p


  • Dynamic Power Management - ATI Radeon HD 4770 GPU delivers high performance when needed and conserves power when the demand on the graphics processor is low
