iPhone 11 is equipped with a completely new Apple A13 Bionic processor. However, this is not the only piece of Apple silicon that is worth paying attention to. During Tuesday's press conference, not a word was said about Apple Tags, U11 chip and orientation in the space of new iPhones.

Apple A13 Bionic – what do we know about it?

A13 Bionic was made in 7 nm second generation lithography. The CPU consists of two high-performance cores (20% faster and 30% more economical than in A12) and four low-voltage cores for low-demanding tasks. The 4-core graphics system has been optimized for API Metal. The 8-core Neural Engine has also been improved, adapted to support artificial intelligence, ubiquitous in iOS. In addition, A13 Bionic also has 6 cores to accelerate matrix multiplication, accelerating machine learning.

The whole consists of 8.5 billion energy-saving transistors. Individual sections will be included only when needed, which will ensure energy saving. According to Apple, B12ic is already ahead of the best Qualcomm and Huawei chips, the A13 leaves them far behind in terms of CPU and GPU performance. Games do not look worse than on PCs – graphics can have anti-aliasing and lighting effects at 60 fps.

A13 Bionic also has a lot of other dedicated sections, including the HEVC hardware codec.

U1 coprocessor – orientation in space

On the slides of yesterday's Apple presentation there was also a U1 chip, which was not mentioned explicitly. Some suspect that his action does not. has been further refined and Apple gave up giving details at the last minute. Therefore, yesterday's press conference lasted an hour and 40 minutes, not 2 hours as usual.

U1 is to provide iPhone 11 orientation in space and the ability to find objects and other Apple devices. We know from the iPhone specifications that it is an ultra-wideband location chip.

Apple informs that the U1 coprocessor will provide the precise location of compatible devices in the room. One application is indicated by the iOS 13.1 specification, which will be released on September 30. By using AirDrop (wireless file transfer between devices), we can simply point the iPhone 11 towards the recipient. Nearby iPhones will be sorted by distance.

iPhone 11 Pro is the first smartphone with Ultra Wideband technology that orientates it in space. (…) Thanks to iOS 13 and U1, all you have to do is point your iPhone towards another person's iPhone and AirDrop will give it priority, speeding up file sharing.

U1 is also associated with the Apple Tag, which we know from unofficial sources. Apple Tag are wireless labels that allow you to quickly find objects to which they will be attached. Space signs in a shopping center or museum can also work in the same way. Thanks to the power of the A13 Bionic system and precise orientation in space, Apple Tag can also be placed in augmented reality. This will greatly facilitate the search for keys and wallet.
