We all know that the crown for the fastest graphics card currently belongs to AMD's HD 5970, but AMD needs something better to pit against Nvidia's upcoming Fermi-based graphics cards. Today our eyes were blessed with new Sapphire HD 5970 card equipped with 4GB of memory, special cooling solution and some higher clock speeds.
The card has three silent fans and big heatsink which makes card three slots high.
Only a couple of AMD partners might introduce HD 5970 4GB card, but as far as we know Sapphire is the only one to provide this card with 2x8-pin power connectors, and not with 2x8-pin plus one 6-pin connector.
The GPU runs at 850MHz, while the memory is clocked at 1200MHz (effective 4800MHz). This is enough for 22K in Vantage Performance. The I\O panel features two dual-link DVIs plus one mini DisplayPort output.
