SAPPHIRE RADEON HD 6990 FEATURES
"AMD Eyefinity technology maximises your field of view across up to three displays, fully engaging your peripheral vision. For gamers this puts you right IN the game and for other applications it helps to increase productivity by maximising your visual workspace so that you can see more windows simultaneously. AMD Eyefinity technology is also ideal for multimedia applications as it allows you to keep several palettes or panels open over a larger workspace whist you edit your images or videos."
Dual AMD Radeon GPUs
"Internal AMD CrossFire X bridge enables parallel GPU Harnessing processing on a single card. The incredible power of dual GPUs with full support for DirectX 11 and scalable geometry processing, Sapphire Radeon HD 6990 is simply the fastest graphics processor in the world."
AMD Stream Technology
"Accelerate the most demanding applications with AMD Stream technology and do more with your PC. AMD Stream Technology allows you to use the teraflops of compute power locked up in your graphics processer on tasks other than traditional graphics such as video encoding, at which the graphics processor is many, many times faster than using the CPU alone."
AMD CrossFireX Multi GPU Technology
"Triple or Quadruple gaming power with AMD CrossFireX Multi GPU Technology. AMD CrossFireX technology supports up to four graphics cards to be used in a single system."
AMD HD3D Technology
"Enjoy the most immersive experience possible with full support for High Definition Stereoscopic 3D, a technique that presents 2D images (movies, games, photos) in a format that creates the illusion of three dimensional depth when using compatible 3D displays with glasses and software."
Microsoft DirectX 11
"Get intense gaming performance and unrivalled image quality with stunning 3D visual effects, realistic lighting and lifelike imagery with Sapphire Radeon HD 6990 graphics cards supporting DirectX11. New features in DirectX11 such as Hardware Tesselation, HDR Texture Compression, Multi-threading support and DirectCompute bring lifelike gaming and an experience never possible on a PC before."
Shader Model 5.0
"Supports Shader Model 5.0 feature set including VTF (Vertex Texture Fetch) which is a key feature used extensively in many of the games that ship today. Without support for this feature the game will fall back to a lesser shader path resulting in the loss of cool, lifelike effects made possible by Shader Model 5.0."
Physics processing support
"Accelerates the performance of Fluid Dynamics, Cloth Simulation, Soft or Rigid Body Dynamics, Universal Collision Detection, Hair Simulation and Finite Element Analysis for the most lifelike gaming experience."
AMD PowerTune Technology
"AMD PowerTune is a breakthrough technology that sets an entirely new direction for maximum performance at TDP. It allows the GPU to be designed with higher engine clock speeds which can be applied on the broad set of applications that have thermal headroom."
AMD Advanced Parallel Processing technology
"Accelerate the most demanding applications by offloading parallel data compute tasks from the CPU to GPU, dividing the tasks as evenly as possible for improved system performance and reliability."
Enhanced Internet Browser Applications
"Not just for video and games, the power of your GPU can now accelerate the latest versions of some Internet browsers (IE9/Mozzilla FireFox) utilising Direct 2D rendering for a faster and more responsive browsing experience including high quality image rendering and media playback."
