FUD Zilla found out ATI's next-generation 40nm performance graphics card will have an RV8x0 codename. The number is still unknown, but it could be RV870 or 880. This 40nm card is expected in Q3 2009, and in the same quarter NVIDIA will roll out its GT216.
This chip should be coming after Q2 2009, so it should launch a bit later, we suspect Q3 2009. Just bear in mind that Radeon HD 4870 and HD 4850 were launched in late Q2 and since RV740 looks quite ready to us, ATI might have its performance 40nm part sooner than many have expected.
