Advanced Micro Devices demonstrated what it called the first DirectX 11-compatible graphics chip at Computex, showing support for features like tesselation. The chip will debut before the end of 2009, AMD said. AMD did not reveal the name of the new chip, or its exact ship date. Microsoft revealed Direct3D 11 in mid-2008, and the API will reportedly be publicly released in July 2009. Its capabilities will only be available to Windows Vista and Windows 7, as well as future Windows operating systems. DirectX 11 is notable for both hardware tessellation and a new compute shader, both explained in greater detail in an ExtremeTech overview. The compute shader will support so-called GP-GPU acceleration, a technique to use the graphics processor as a form of general-purpose compute engine. AMD calls this technology its Stream technology; at Computex, AMD demonstrated drag-and-drop transcoding using ATI Stream technology, where an HD media file was encoded in 82 seconds, versus an encoding time of 160 seconds without ATI Stream acceleration.
