SAPPHIRE Technology is now shipping a new model of the highly acclaimed SAPPHIRE HD 4770 - a powerful midrange graphics card for enthusiasts on a budget, now with better connectivity and a custom cooler by Arctic Cooling.
The earlier SAPPHIRE HD 4770 was the first card in its class to use GDDR5 memory and was based on the first ever GPU built in 40nm process technology, but was quickly sold out. The new model is a SAPPHIRE original design based on the same GPU and a special cooler built exclusively for this product by Arctic Cooling. The new SAPPHIRE HD 4770 also features native HDMI, VGA and DVI connections on the rear bracket, supporting a wider range of displays without the use of adapters.
The SAPPHIRE HD 4770 uses the powerful graphics architectures from the ATI division of AMD, incorporating multi-purpose stream processing units and improved memory management architecture. With 640 stream processors – twice as many as previous generation mid-range cards - and core clock speed of 750MHz, together with 512MB of GDDR5 memory clocked at 800MHz (3200MHz effective), the SAPPHIRE HD 4770 delivers stunning performance for gaming or image rendering at a mid-range price.
The new 40nm core technology delivers all of this with reduced power consumption, making the total power requirement of the card only 80Watts and typically less in operation as a result of dynamic power management. And of course, the SAPPHIRE HD 4770 supports DirectX10.1 for enhanced rendering performance and special lighting effects now being implemented in the latest games.
The SAPPHIRE HD 4770 series uses the PCI-Express Gen2 interface, and features connectors for CrossFireX bridge cables, allowing two or more cards to be used together on a CrossFireX compatible mainboard for higher graphics performance.
All of the SAPPHIRE graphics cards in the HD 4000 series incorporate the latest ATI Avivo™ HD Technology for enhanced Video display. They feature a new generation of built in hardware UVD (Unified Video decoder) considerably reducing CPU load and delivering smooth decoding of Blu-ray™ and HD DVD content for both VC-1 and H.264 codecs, as well as Mpeg files. Integrated upscaling technology delivers the best quality DVD video images. With the latest drivers, the SAPPHIRE HD 4770 also offers ATI Stream processing for the acceleration of video transcoding and other supported applications.
SAPPHIRE HD 4000 series graphics cards are Microsoft Windows Vista™ Premium certified and supported by the ATI Catalyst® suite of software, ensuring customers have ongoing access to software updates for performance, stability and added features.
