semiconeng, Sorry Joe, the numbers don't add up.... ...A yield of 48%, doesn't sound too good to me. I said: 3.6 M would be acceptable (but not outstanding) yield. We may argue about some percentages up and down, for example you said: Wafer Area / Die Area = Total Die Per Wafer 31,400 / 117 = 268.37 Die Per Wafer But let's be fair, and count for partial die, and say 250 Die Per wafer. I am no expert in the field, but I have seen losses on edges and between individual die amount to more than that. Also, I don't know if 117 mm^2 is the official numner. I have used 120 mm^2 for Tbird. 3.6 million chips claimed by Jerry is the number of chips sold (which may be limited by the availability of chipsets). It is also a number that is the worst case scenario for AMD, because they sure don't want to miss it. They will most likely produce more. I guess these minor points combined will result in a yield in the 50s which again is acceptable (but not outstanding) yield. Joe
