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 290 Vapor-X OC features several of the company's industry-leading 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 2560 Stream Processors, the SAPPHIRE R9 290 Vapor-X is an Overclocked edition which boasts 4 GB of the latest GDDR5 memory running at 1400 MHz (5.6 GB/s effective) and high speed engine clocks of 1030 MHz. 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.
