Apple, TSMC reportedly ramping up 10nm chip mass production for use in future iPhones
Reports from China suggest that the major chip fabricators are all readying mass production of 10nm process processors, including Apple's manufacturing partner TSMC for multiple companies.

According to supply chain reports from DigiTimes besides just for Apple's future A-series processors, TSMC will supply the Helio X30 and X35 for MediaTek, between the end of 2016 and 2017.
TSMC is also expected to provide chips for HiSilicon, which will ultimately find its way into Android-based Huawei flagship phones.
Apple's A10 Fusion chip as found in the iPhone 7 family utilizes TSMC's 16nm FinFET process. Apple's A9 in the iPhone 6S family and iPhone SE, and A9X processors found in the 12.9-inch iPad Pro use the same size die.
Two otherwise identical chips with different die sizes have less the current used on the chip manufactured with the smaller die. As a result, in most cases the generated heat is less, and the power demanded by the smaller die size chip is lower as well.
Qualcomm has also recently announced its 10nm mobile chips will be fabricated by Samsung, with shipment of the Snapdragon 835 in commercial devices in the first half of 2017. Samsung's as-yet unrevealed Exynos evolution is also expected in the first half of 2017.
Smaller die sizes are in development at this point. IBM has built the first functional chips with 7nm technology, with consumer products with the technology likely at some point in 2019.

In 16FF the transistor went to TSMC's 16NM node but the metal layer connections were still from the 20NM node. So you have faster and more power efficient transistors on top of a larger spaced connectivity grid. In FFC, the designers could put those transistors closer together if they wanted to. Designers space transistors differently depending on power and heat, crosstalk, etc. The efficiency cores running at a lower speed are probably more tightly spaced taking advantage of the new metal layer.
So you should consider the 2016 A10 as a further shrink in process node. TSMC's 10NM node will be a shrink of both the transistor and the underlying wiring in one generation.
