The ‘world’s only’ 8GB edition of AMD’s flagship 290X graphics card has gone on sale.
The Sapphire R9 290X Vapor-X OC features 8192MB of GDDR5 video memory running at 5600MHz, a 1060MHz core speed, 2816 stream processors and a 512-bit memory interface.
The memory capacity doubles the 290X’s original 4GB provision and additionally tops that of AMD rival Nvidia’s Titan Black card, which runs on 6GB of VRAM.
The 290X 8GB is said by retailer Overclockers UK, which currently has the exclusive rights to the product, to be “perfect for a 4K setup”.
The card includes two dual-link DVI connetions, a HDMI output and a DisplayPort. At least 600W of power supply is required, as well as eight-pin and six-pin cables for power.
The ‘Vapor-X’ moniker refers to the trio of fans sat on top of the card, which employ a choke design claimed by Sapphire to improve power efficiency by 25 per cent.
The card also includes the custom card firm’s ‘Intelligent Fan Control’, which means only one fan will operate when the card is under low workload.
The Sapphire R9 290X Vapor-X OC 8GB is available now for £600.
