RV670, ATI's first 55 nanometre chip turns out to be better than anyone inside ATI expected. ATI planned to have the chip ready in very early Q1 next year but for the first time in ATI's history the A11 silicon doesn't need a re-spin.

Traditionally A12 was ATI's production revision but it looks like that A11 is bug free and that it is ready for production.

It was about time that ATI got something right.
