Computex: AMD announces DirectX 11 GPUs in 40nm
AMD's Rick Bergmann and TSMC's Dr. John Wie presented the first 40 nanometer wafer at the Computex and showed demos with Compute Shader and Tesselation support.
On which graphics cards the new 40nm DirectX 11 chips will be used, has not been revealed by AMD yet; as a schedule only "later this year” was given. Interesting about the new GPUs is, besides the smaller production process, the support of DirectX 11.
The most important features of DirectX 11:
• Tesselation: Tesselation allows the visualization of complex, detailed objects with many curves and a high number of polygons.
• Compute Shader 5.0: With Compute Shader 5.0 the GPU can for example be used to accelerate the conversion of video material.
The utilization of Tesselation and compute Shader 5.0 has been presented with several demos. So for example with activated Tesselation more details are displayed in a snow covered mountain scenery or on characters. The transcoding of a HD video for a mobile device took only half as long if the acceleration with Compute Shader 5.0 was activated.
Thus the rumors that AMD will be first to introduce DirectX 11 compatible graphics chips and increase the technology advantage is confirmed.
Nvidia on the other hand is said to have finished the tape-out of the new GT300 chip, but a schedule for the release has not been specified say sources at bit-tech.com. Furthermore the GT300 will, like AMD's RV740, be produced in 40 nm by TSMC. So the problems in production TSMC is having are affecting both manufacturers - more information, confirmations or denials are expected on the Computex.
