In response to a question from an analyst, Intel CEO Brian Krzanich said that the company is now providing engineering samples of its first 10nm product, code named Cannon Lake, to customers.
The executive then went on to say that the yield rates "are continuing to improve pretty much right in line with the forecasted ramp rates."
Seemingly in defense of the company's rate of progress, Krzanich then said, "It's a new technology, so you always have some problems to get solved, but we're pretty comfortable with where we're at right now."
