Yeah ignore the percentages I balls'd them up, Nvidia are meant to be getting 20 working gtx480's from every 1000 wafers is what I should have said. Ive also just read TSMC could be at 20,000 a month now, so ignore 60 a month too.
The numbers are simply wrong I'm afraid, 2% yield was where it was on A1, literally getting only 7-8 samples across 3-4 wafers they sent for tape out. Its supposed to be higher, but still single digit, so around 8-9% gives them around 10 per wafer, not every 1000 wafers.
They supposedly put through 9k wafers as hot lots so should have around 9k wafers capable of providing 10 or so cores per wafer, thats 90k cores working at one speed or another. I reckon, judging by the times its taken, they've spent a LONG LONG time testing those wafers insanely carefully to get every last working core out and I reckon we'll see insanely limited numbers on the 480gtx limited numbers of 470gtx's, and after a couple weeks a number of 460gtx's, which will likely be even slower with less SP's, and frankly will be hard pushed to beat a 285gtx.
