We´ve heard a rumour saying that ATI plans to discontinue 40nm RV740 chip due to its very bad yields and before this escalates any further, let us simply say that this is not true.

We checked with multiple sources and people in the know said “this is absolutely not true” and we don´t have any reason to doubt them.

Same sources have confirmed that yields are not as good as ATI would like them to be and at the same time, demand for this product is huge but 40nm yields are getting better and the situation is improving.

If anything, RV740 40nm was a vessel product and a learning curve for RV870, next generation performance 40nm chip, scheduled for launch later this year.
