yield of 12" wafer of tsmc in 2010 for 40nm or 45nm
70% is better than 40%
If TSMC have improved their yields from 40% to 70% in the past few months, then AMD and their other customers will be far happier. They would have been worried that they wouldn't get above 50%!
And at <$40 a die for Cypress (and how cheap would the new 400SP Redwood be, at ~110mm^2?) AMD hopefully are making a few bob whilst they can!
Better than Toms Hardware who claimed AMD were getting 4% yields yesterday...
