Paul , for a PHD that is pretty simple maths As you state the K6-3D is 81mm so I used 320 dies per wafer . The 320 is an approximation but should be near to the mark 50% yield gives 160 dies per wafer . at 1000 wafers per week and 13 weeks in the quarter you get :- 160x1000x13 = 2.08M K6-3D per quarter Obviously I was referring to the quarterly production of K6-3D , I don't know how your brain was thinking .

Paul, calm down, Brian's number (2M K6-3D) is right for the QUARTER, which has THIRTEEN (not ONE) week if there are 1000 wafer starts PER WEEK. AMD said in CC that they are NOW at 1500 wafer starts/week, but these won't be coming out until the end of the quarter. I believe a month ago, when Ashok Kumar made his famous "almost 50% yield" announcement, AMD was at 1000 wafer starts (0.25) per week. These will be coming out in May. April production is unknown, but if we assume that late Jan./early Feb wafer starts were 500/week, then the wafer starts will average 1000/week. It is possible that the production yields will be higher or lower than 50%, since this already assumes a small improvement over what Kumar reported. But 2M K6's per quarter is about the right number if wafer starts average 1000 per week. Petz
