Since the company believes this is the best way to keep all of the shading units well-fed, the target is to have 16 pixels out in every clock, regardless of how complex the pixel might be. But, don’t think for a second that R600 is weaker than G80 on the account of ROP units alone.You can read it all over here.
We also learned the reason why the product was delayed for so long. It seems that ATI encountered yet another weird bug with the A0 silicon, but this one did not lock the chips at 500MHz, but rather disabled the Multi-sampling Anti-aliasing (MSAA). At press time, we were unable find out if the A1 revision still contains the bug or not. Retail boards will probably run A2 silicon.
ATI R600 only processes 16 pixels per clock
