Following recent rumors that AMD has given a green light to its AIB partners for an 8GB version of the Radeon R9 290X graphics card, Sapphire has now officially announced a new model in its Radeon R9 lineup, the Sapphire R9 290X 8GB Vapor-X OC.

Based on AMD's Hawaii GPU with 2816 Stream Processors, the new Sapphire R9 290X 8GB Vapor-X graphics card is also a part of Sapphire's Overclocked Edition, which means that it will feature a factory-overclock which puts the GPU at 1030MHz while 8GB of GDDR5 memory paired up with a 512-bit memory interface ended up clocked at 1375MHz (5.5GHz effective).

Sapphire has decided to pair up the new 8GB Radeon R9 290X graphics card with its well known Vapor-X series cooler which features vapor chamber technology as well as the Tri-X structure with five heatpipes (10mm main, two 8mm and two 6mm) and three 90mm fans with two sets of dust repelling ball bearings and aerofoil section blades for maximum airflow and minimum noise. Sapphire also included a new feature called the PCB Component heat spreader which uses an additional heatsink mounted directly on an exposed part of copper PCB layer, which should reduce the temperature even further.

The new Sapphire R9 290X 8GB Vapor-X OC also features a custom PCB with 10-phase VRM with Direct-FET technology and Sapphire Black Diamond chokes. The new Sapphire R9 290X 8GB Vapor-X OC also comes with two DVI, HDMI 1.4a and Display Port outputs, making it perfect for three monitor Eyefinity setup, without the need for an active adapter, or recently popular 4K/UHD setups.

Unfortunately, Sapphire did not reveal any details regarding the price but did note that the new Sapphire R9 290X 8GB Vapor-X OC is currently shipping and should be showing up on retail/e-tail shelves. We have only managed to spot a non-OC version of Sapphire R9 290X Vapor-X Tri-X 8GB graphics card which is listed at around €670.
