Sapphire Radeon Vapor-X HD 7970 GHz OC 3GB DDR5 DL-DVI-I/SL-DVI-D/HDMI/DP PCI-Express Graphics Card (11197-12-40G )

SAPPHIRE HD 7970 3GB Vapor-X Edition has the latest GDDR5 memory clocked at 6000MHz effective, and runs with a core clock speed of 1000 MHz which with Power Tune Dynamic Boost rises to 1050 MHz on the engine. It has a slightly less sophisticated 8-phase power design and the versatile output configuration of Dual-link DVI-I, DVI-D, HDMI and Display Port. The Vapor-X cooler is based on a new vapor chamber designed especially for this series. Heat is carried away by four heat pipes (2 x 8mm plus 2 x 6mm), and finally dispersed by two 90mm fan with aerofoil blades and dust repelling bearings. The Vapor-X cooler easily handles the heat generated from the HD 7970 GHz Editions even under extreme load conditions.
