Apple's recently announced fourth-generation iPad Air has Touch ID integrated into the sleep button. This means that Touch ID has been integrated into a smaller area than the previous home button. Apple executives have talked about the difficulties in developing it in a podcast (also available on YouTube).
Bob Borchers, Apple's vice president of product marketing, and John Ternus, vice president of hardware engineering, revealed the positioning of the current iPad lineup and some of the development process for the fourth-generation iPad Air.
First, speaking about the new iPad Air, Borchers said that implementing the Touch ID sensor into the top button was "an incredible feat of engineering." And Ternus explained that the narrow aspect ratio of the sensor made it quite challenging to implement. The sensor needed to be "incredibly sensitive" and would have to take time to capture a wider view of the fingerprint in the initial enrollment process.
In addition, the cellular model of the iPad Air has an antenna at the top of the enclosure, so a great deal of effort was put into making sure that the Touch ID sensor and the antenna did not interfere with each other, he said. Ternus added that with "hardcore silicon and engineering", the fingerprint sensor has achieved the same level of security as previous versions.
In this regard, Borchers says the A12Z is "optimized for pro workflows and experiences, especially those that may be more graphics-intensive." The difference between the two, he said, is that the A12Z has an advantage on "things that may be more graphically intensive," while the A14 offers "all-around amazing capabilities."
It's true that the A12Z has more CPU and GPU cores than the A14, and the above (unverified) benchmarks show that the A12Z has a superior multi-core score, so Borchers' statement seems to be a fact. On the contrary, it may have been designed that way to balance the Air and Pro models on the iPad lineup.
