* Advanced Memory - GDDR5 memory provides twice the bandwidth per pin of GDDR3.
* 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.
* 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.
* Unified Video Decoder 2 (UVD 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.
* 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.3 Full 1080p files can be converted to H.264 and MPEG-2 up to 1.8x faster than real-time.3
* Upscale Beyond 1080p - Watch the hottest Blu-ray movies or other HD content at full 1080p display resolution and beyond.1
