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.
-Power to Spare
This GPU has the brute processing power needed for physics, artificial
intelligence, stream computing and ray tracing calculations.
-Accelerated Video Transcoding (AVT)
With ATI Stream technology, owners of ATI Radeon™ HD 4770 GPUs can
help accelerate the conversion of standard
and HD video into multiple formats for use on differing consumer
electronics devices. The ATI Video Converter,
designed to enable GPU transcoding of HD video streams, is
currently available.
-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.
-HDMI
Enjoy the latest audio technologies using HDMI with 7.1 digital
surround sound support. Also, xvYCC support allows the user to enjoy a
wider range of color when connected to a capable HDTV.
