Mickey, Just for fun let's figure at 184mm2 that there will be 130 possible good die/wafer. 25/130= ~20% yield. That's probably the minimum I would expect for the first production run. So to make a couple hundred fifty thousand chips for release they would need about 10,000 wafers to be started at least 10 (2.5 months) weeks before introduction. So if they want to release the K7 on June 23 they will need to start these wafers on or near the first week of April. If they wanted to release by first week of April they would have to have started the wafers by now. Am I safe to assume that they wouldn't start that many wafers before the chip was totally (or nearly totally) debugged or can they fit certain bugs during the processing of wafers? Jim
