Redefine HD Gaming

The ATI Radeon HD 4800 Series GPUs deliver a cinematic gaming experience with unprecedented performance. The powerful new TeraScale graphics will propel you deep into your gameplay with seamless frame rates and high resolutions. Enhanced anti-aliasing (AA) and anisotropic filtering create striking graphics with unparalleled realism so you can max out the settings of the most demanding next-generation games or revitalize your favorite titles. Play today while preparing for tomorrow with tessellation, support for DirectX® 10.1 and scalable ATI CrossFireX^TM technology.

ATI Avivo^TM HD Technology

ATI Avivo^TM HD is the advanced image and video processing and display technology found in ATI Radeon^TM HD GPUs and ATI Theater^TM video capture processors. Specifically designed for HDTV and HD video enthusiasts, ATI Avivo HD provides brilliant colors, sharp images, smooth playback of Blu-ray^TM* and HD video content, HDMI with built-in multi-channel digital audio, and on some GPUs, Unified Video Decoding (UVD). UVD is designed to enable a cool and quiet media PC with low CPU power requirements and playback of HD 1080p content. HD Monitor is required for full 1080p enjoyment.

HDMI Video and Audio

A system with an ATI Radeon^TM HD 4800 Series graphics card can help enhance the HD entertainment experience by providing a seamless connection to an HDTV or home theater system. With built-in 7.1 surround sound audio (AC3 / DTS ), the new GPUs and graphics cards support single cable connection directly to a compatible HDTV, projector or receiver. This single cable carries both the HD video and 8 channel audio for a clean, high definition connection. Some graphics cards will be equipped with an HDMI connector, while others will output the HDMI signal using a special ATI Radeon DVI-I to HDMI adapter. These options give consumers more options and flexibility when connecting their PCs to monitors or home theaters for maximum enjoyment of HD content. The new GPU also supports xvYCC color which can display a wider range of color when connected to capable HDTVs.
