  ''While AMD will tell us that R600 is not late and hasn't been delayed, this is simply because they never actually set a public date from which to be delayed. We all know that AMD would rather have seen their hardware hit the streets at or around the time Vista launched, or better yet, alongside G80. But the fact is that AMD had quite a few problems in getting R600 out the door.
  
  While we couldn't really get the whole story from anyone, we heard bits and pieces here and there during our three day briefing event in Tunis, Tunisia. These conversations were short and scattered and not the kind of thing that it's easy to get a straight answer about when asking direct questions. Keeping that in mind, we do have some information and speculation about a few of the road bumps AMD faced with R600.
  
  Apparently, the first spin of R600 silicon could only communicate over the debugging interface. While the upside is that the chip wasn't totally dead, this is not a good problem to have. We also overheard that a later revision of the hardware suffered from fragments getting stuck in pixel shaders. We even overheard one conversation where someone jokingly remarked that AMD should design hardware but leave the execution to NVIDIA.
  
  In a wild bout of pure speculation on our part, we would have to guess about one other problem that popped up during R600's creation. It seems to us that AMD was unable to get their MSAA hardware to work properly and was forced to use shader hardware to handle MSAA rather than go back for yet another silicon revision. Please know that this is not a confirmed fact, but just an educated guess.''
