The new SAPPHIRE HD 4770 is the first card in its class to use GDDR5 memory and is based on the first ever GPU built in 40nm process technology. It uses the powerful graphics architectures from the ATI division of AMD, incorporating multi-purpose stream processing units and improved memory management architecture.

Advanced Memory
GDDR5 provides twice the data per pin of GDDR3 memory at the same clock speeds.

Enhanced Anti-Aliasing (AA) & Anisotropic Filtering (AF)
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.

Microsoft 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.

Power to Spare
This GPU has the brute processing power needed for physics, artificial intelligence, stream computing and ray tracing calculations.

Unified Video Decoder 2(UVD 2)
Unified Video Decoder 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.
