In a few months AMD will unveil their DirectX 11 graphic chips. As expected beginning with the performance chip RV870, which the details are already quite precise about, which though were not yet confirmed by another source.
Meanwhile we could figure out that there are many other AMD DirectX 11 graphic chips planned for this year - this also matches with AMD's last statements.
According to our information on hand AMD will introduce at least three DirectX 11 graphic chips within this year, two of them surely produced in 40 nm.
So the performance chip RV870 is followed by the dual chip R800. Additionally, the middle class chip RV840 is said to join the AMD portfolio this year.
We do not have any information about a potential RV810 chip for the low budget segment yet.
