The A11 Bionic chip of the iPhone X and the iPhone 8 took Apple three years of work

The A11 Bionic processor that includes the iPhone 8 and the iPhone X is the most powerful smartphone chip Apple has ever created, but making a processor as perfect for artificial intelligence tasks as the A11 has not been an easy task. has long led the Cupertino company.
In an interview with Mashable by Apple's hardware technology vice president Johny Sroujiand chief marketing officer Phil Schiller , Apple reveals that it took them three years to find the perfect solution for their new chip .
The company usually starts with the development of its processors three years in advance. When Apple launched the iPhone 6 in 2014, with the A8 chip , there were no indications that they were working on artificial intelligence at the mobile level, however, they were already very clear that soon they would need a neuronal motor in their chips to be able to support certain functions In the near future.
According to Srouji, the development process at Apple is flexible to changes, so if a team comes to him with a proposal that was not in the original plan, his reaction is, in his words: "We need to make that happen. We do not say, 'No, let me go back to my road map, and five years later I'll give you something.'

A11 Bionic: designing the perfect processor

The fact that Apple designs its own processors is one of the biggest advantages it has over its competitors. The other companies have to rely on chips created by other companies. However, Apple can create a chip that perfectly suits your needs .
Thanks to this, different divisions of Apple, such as Schiller's marketing group or the screen team, can go to Srouji's team and tell them what they think they'll need in three years. Then, the team decides whether they are going to rely on the design of their previous chips or if it is better to start from scratch.
The Bionic A11 chip also contains the first GPU designed by Apple , unlike its previous chips, which contained a GPU Imagination Technologies. This allows Apple to further control and refine the integration process between software and hardware, from start to finish, and how they interrelate one to the other.
"It's not about Lego pieces assembled together," says Schiller, "the team has designed the components of the A11 Bionic to work together."
Apple mentioned the A11 Bionic's Neural Engine several times during last week's keynote. It is a hardware component that allows for automatic learning tasks within the device itself.Automatic learning is a form of artificial intelligence that empowers computers to learn by observation, and is able to do incredibly fast calculations that require neural networks and, at the same time, be ultra-efficient.
Schiller has also confirmed to Mashable that the secure element of the processor has been redesigned , although he has avoided going into details, apart from stressing that Apple takes security "very seriously . "
Of course, the process is not always perfect. Schiller has revealed that there have been times when Apple has had to include changes that had not been planned by any of the teams:
"There have been some crucial things in recent years when we asked Johny's team to do something that was not scheduled, in a different sense from what they had seen for years, and have moved heaven and earth and done it , and it's awesome to see it. "
But in the end, Apple totally makes up for all of this work. The Bionic A11 chip is so powerful that early benchmarks suggest that its performance is on par with that of the latest 13-inch MacBook Pros in some areas .
However, Apple does not rest on its laurels: according to Srouji, are already developing great novelties for the future:
"We are already looking to the future, I can tell you this, and I do not think we will be limited," he said, adding that "it is becoming more difficult . "
