The new SAPPHIRE HD 4670 GDDR4 has been production engineered by SAPPHIRE to bring new levels of performance to the mainstream previously associated only with high end cards. With its 320 stream processors and carrying 512MB of GDDR4 memory the SAPPHIRE HD 4670 GDDR4 is now the best product in its class. Clock speeds are 750MHz for the core and 1100MHz (2.2GHz effective) for the memory making this the fastest HD 4670 card available. The card is cooled by a new large diameter fan based cooler which keeps noise levels to the minimum (<20dBA).
