Sapphire HD 4870 1GB VAPOR-X Computing

Review

SAPPHIRE Technology was the first company to implement cooling for PC graphics cards based on Vapor Chamber Technology. Vapor Chamber Technology was previously used in blade servers to provide more efficient yet compact cooling. SAPPHIRE’s Vapor-X cooler was introduced in 2007 with its HD 3870 ATOMIC Edition graphics card and then rolled out to the global market with the successful TOXIC HD 3870 and HD 4870 series. Based on the successful experience on TOXIC with Vapor Chamber cooler, SAPPHIRE introduces the new Vapor-X graphics card series to bring an users a silent and efficient cooling solution based on Vapor Chamber technology. With such a efficient cooling system, the Vapor-X series has a more potential in overclocking and longer life expentancy.
