Believe it or not - the best just got better. For the first time ever, 2.4 teraFLOPS of graphics horse power, 1600 stream processors and 2 GB of GDDR5 memory have been combined to create the fastest and most powerful graphics card available today.¹

• Dual TeraScale graphics engines work in tandem to deliver blazing frame rates, putting the power of graphics ‘supercomputing’ in the hands of extreme gamers.
  
• 1600 stream processors and 230GB/sec of memory bandwidth provide the brute power needed to tackle the most intense 3D games, even those with artificial intelligence, physics operations and tessellation.
  
• Unparalleled anti-aliasing (AA) and anisotropic filtering delivers striking graphics with extraordinary realism so you can max out the settings of the most demanding next-generation games.
  
• Regardless of platform, these graphics cards delivers the power needed to blaze through games while dynamically conserving energy at idle or when demand is low.
  
• ATI CrossFireX™ technology with quad GPU support in dual mode offers superior scalability so you can take your game to new heights.
  
• Watch the latest Blu-ray and HD movies play with incredible fidelity and have the freedom to edit videos and convert video formats at lightning-fast speeds.²

Go Beyond HD Video
Unified Video Decoder 2 (UVD 2)
UVD 2 frees up your CPU for the most processing-intensive content, including VC-1, H.264 and MPEG-2. 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.1 Full 1080p files can be converted to H.264 and MPEG-2 up to 1.8x faster than real-time¹

Upscale Beyond 1080p
Watch the hottest Blu-ray movies or other HD content at full 1080p display resolution and beyond.²

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.

Advanced Connectivity
Enjoy the latest audio technologies using HDMI with 7.1 digital surround sound support. Also, HDMI with xvYCC support allows the user to enjoy a wider range of color when connected to a capable HDTV.

¹ As of August 12th, 2008, the ATI Radeon™ HD 4870 X2 is the fastest, most powerful graphics card based on the 3DMark Vantage v.101 extreme top score of 6920.  ² HD capable monitor required. ³ ATI PowerPlay™ technology consists of numerous power saving features. Not all features may be available in all ATI Radeon HD 4800 Series graphics cards.
