Keep in mind that 10nm will be about 12-18 months later than planned and that it is the 2nd gen of SADP, so that will be more matuire. So I would expect healthy yields from the start, that's the whole reason for the delay. The only thing that 10nm needs isn't mature health, but better health than 14nm at same point in development. Because of the improvement in density, cost will be better (although offset for a part by bigger dies).Edit: The article does not mention Coffe Lake, and only the last paragraph is about Cannonlake, which we already know.
