Vapor chamber strapped to hot-clocked Radeon R9 290
 

Sapphire has added another hot-clocked Radeon to its stable. The R9 290 Vapor-X OC features the same, 2560-shader version of AMD's Hawaii GPU as other R9 290 cards. However, instead of clocking the chip at the default 947MHz, the Vapor-X cranks it to 1050MHz. The 4GB of onboard memory is faster than stock, too: 5.6Gbps versus 5.0Gbps in the reference card.
