A Chinese web-site has published brief technical details about ATI’s future mainstream visual processing unit that should be announced in short-term future and be opposed to NVIDIA’s GeForce 6600-series GPUs unveiled last week.

Rather unexpectedly, ATI’s code-named RV410 graphics processor is said to resemble NVIDIA’s higher-end flavour of the GeForce 6600 family in terms of specifications. The new mainstream chip from ATI will have 8 pixel pipelines, 6 vertex pipelines and native support for PCI Express x16 bus. The technology will inherit feature-set of the RADEON X800-series products and will sport such technologies as Shader Model 2.0b, 3Dc and other, according to a report from HKEPC.com web-site.
