We learn from Rage3d forum that RV770, ATI next flagship product has two versions of silicon, A11 and A12. Now ATI has decided to use A 12 as the final silicon for RV770.

A12 version of RV770 is already in production right now at TSMC. Compared with 1.26v core working voltage of A11, ATI managed to lower the core working voltage of A12 to 1.13v. But both A11 and A12 version of RV770 use 102-B50102-00 PCB board and 16Mx32 HYB18H512321BF-10 Qimonda GDDR3.

We’re sure there’s no A13 or A14 version of RV770 in the near future. ATI will announce RV770 series graphics cards at June 16.
