I have a hard time believing them too, not only are they really low, but also too close together. The margins would probably be non-existent.
While i dont believe this prices too (makes no business sense for AMD) ,why do you say that ? Barts supposed to be 230mm2 , nvidias GF104 (aka GTX460 cards) are 330mm2 die size.Youre saying Nvidia losses BIG TIME on every 460 out there ?
As i see it ,those prices are totally doable, however due to weak competition ,i doubt that they will be true, probably around mid way between those and 58xx series ATM stand at.
