It had been industry speculation prior to the iPhone 6S launch that Apple would be dual-sourcing the A9 and A9X from Samsung and TSMC, respectively. The A9 would have gone into iPhone 6S/6S+ and the A9X would have gone into iPad Pros, giving Samsung a large edge in volume for the A9 product family.
