SAPPHIRE Vapor-X HD 5870 1GB Video Card Pictures and Specs Announced
Sapphire just sent over some specifications and pictures of their Vapor-X HD 5870 1GB Video Card. It has been just recently revealed that the Vapor chamber technology used in SAPPHIRE Vapor-X coolers comes from Microloops. Vapor-X has very efficient heat dissipation, which helps to remove heat quickly GPU better than the stock cooling solution by ATI. The card is rumored to be coming out on November 3 along with a new Sapphire Radeon HD 5750 with Vapor X. The ATI Radeon HD 5870 reference model comes clocked at 850MHz on the stream processors and on the Vapor-X edition they are clocked 20MHz higher at 870MHz. That means this card is slightly overclocked right out of the box, which is nice for an extra performance boost. You can find tons of pictures and the full specs of the card in our forums by following the link below.
Vapor Chamber Technology is based on the same principles as heatpipe technology. A liquid coolant is vaporised at a hot surface, the resulting vapor is condensed at a cold surface then the liquid is returned to the hot surface. The recirculation process is controlled by a wick system. SAPPHIRE Vapor-X flattens the whole system into a slim chamber – which in the graphics application is mounted in contact with the surface of the graphics chip. Actually, the coolant is water but because the chamber is evacuated to a very low pressure, the vaporisation process occurs at a much lower temperature than normal boiling point. The complex wick arrangement inside the module controls the flow of water and water vapor so that the system can be used in any orientation.
