SAPPHIRE technology, the leading manufacturer and global supplier of AMD-based graphics products, has just announced an exciting new model in the successful R9 series of graphics cards. The SAPPHIRE R9 290X 8GB Vapor-X OC adds an industry leading 8GB frame buffer to the company's award winning cooling technologies and a factory overclock to deliver best in class performance with very low noise.

Based on the award-winning Graphics Core Next (GCN) architecture from AMD with 2816 Stream Processors, the SAPPHIRE R9 290X Vapor-X is an Overclocked edition which boasts 8GB of the latest GDDR5 memory running at 1375MHz (5.5GB/s effective) and high speed engine clocks of 1030MHz. Together these clocks deliver industry leading performance - but to achieve this performance with stability and reliability demands high quality components throughout the design (especially in the power control circuitry) together with a sophisticated cooling solution.
