Features:

The new TeraScale graphics engine features up to 1.2 teraFLOPS, nearly one billion transistors and up to 800 stream processors so you can enjoy the high resolutions and fast frame rates previously only available with dual-card systems.

Equipped with the fastest, most advanced GDDR5 memory technology, this GPU supports higher data rates which translates directly into superior performance and maximum memory bandwidth.

Get right in the action and experience cinematic gaming with mind-blowing performance in the latest DirextX 10.1 games.

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.

Accelerated Video Transcoding (AVT) allows you to convert videos to H.264 and MPEG-2 formats up to 19x faster than when using a just CPU.

More Performance Per Watt - ATI Radeon HD 4800 series delivers up to 2x the performance per watt of AMD’s previous generation GPUs
