Tear through the latest games with seamless frame rates and go beyond HD1 with the power of the ATI Radeon™ HD 4890 graphics processing unit (GPU). Building on the strength of the ATI Radeon™ 4800 series award-winning architecture, this GPU stands out from the rest with massive graphics processing muscle. Take ultimate control over your game and crank it up with scalable performance. Go ahead, max out the settings and put the ATI Radeon HD 4890 through its paces.

TeraScale Graphics Engine

  • The TeraScale graphics engine in the ATI Radeon™ HD 4890 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.

    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.

    Unified Video Decoder 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,2.

    Accelerated Video Transcoding (AVT)

  • With ATI Stream technology, owners of ATI Radeon™ HD 4800 series graphics cards 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.

    Dynamic Power Management

  • ATI Radeon HD 4890 GPUs deliver high performance when needed and conserve power when the demand on the graphics processor is low.

    Energy Efficient Manufacturing Process

  • Second generation 55nm chip uses the industry’s most energy efficient manufacturing process.
