AMD-ATI will release R670 graphic card composed by two RV670 cores in next Jan to against NVIDIA GeForce 8800 Ultra.
As the base of R670, RV670 Radeon HD 2900 PRO will launch in this Q4 and replace RV570 Radeon 1950 PRO. It will be between R600 and RV630. RV670 will use 55nm technology and it is also the AMD-ATI only this kind of product in 2007.
We thought it is more possible to use single card-dual chip while not dual card-dual chip mode.
If R670 come on time, then, AMD-ATI possible release R700 6 months later (around July, 2008) and upgrade to R780 at the end of 2008.
The only bad news is that R670 will miss this Christmas Day.
