Are we talking about metal or silicon respins? Dunno why nV has only one letter and one number in the spin code - while ATi lists both silicon and metal spins. Anyways, if ATi's A0 was first revision then R600 would have gotten unrealistic total of 4 four respins, as early samples were A11 (1st rev silicon, 1st rev metal) when retail chips were A13. More likely, ATi's first rev is A11 meaning R600 had two metal respins (A11 -> A12 -> A13).

And, I haven't seen any nV, nor ATi, chips marked A0...

Of course you haven't, A0 is usually in-house only. Only chip I can think of that released as an A0 from NVidia is the NV15. Usually it takes a few revisions before they can release.

Also, the R600 DID take several respins before it could release if you remember. You're talking about a card that was 6 months+ late.

Now again, all that could have changed since then, but I've never heard or read anything to tell me that. I'd ask the reps, but that's likely information they aren't willing to let out.
