Apple A15 “lasts forever” for another year, the new A16 “squeezes toothpaste”

In the early morning of September 8th, Beijing time, Apple held a fall conference with the theme of “Super Forward Looking” at the Jobs Theater at its California headquarters.

At the press conference, Apple released a number of new products, including the new Apple Watch, the new AirPods Pro and the much-anticipated iPhone 14.

The two basic models of the iPhone 14 of different sizes have not been upgraded, and are equipped with the A15 processor used in the previous generation of iPhones, while the Pro model, which uses a new “pill screen” appearance, has upgraded the processor to A16. Leifeng Network

Apple said at the press conference that its competitors are still chasing the performance of its three-year-old A13 processor, and Apple is far ahead in terms of mobile phone processor performance. The new A16 processor will focus on power efficiency, display and image performance improvements.

The A16 processor is manufactured using TSMC’s 4nm process and integrates 16 billion transistors on the chip, making it the mobile SoC with the largest number of transistors at present. A16 has a 6-core CPU and a 5-core GPU, of which the CPU includes 2 performance cores and 4 energy efficiency cores, and is equipped with a new 16-core neural engine, which increases the computing power per second from 15.8 trillion times of the previous generation to 17 trillion times. .

Apple said that compared with the A15, the A16’s performance core is faster and consumes 20% less power, while the power efficiency core consumes only one-third of the competition.

In addition, the A16 memory bandwidth has been increased by 50%, and the new display engine coprocessor can support the display of the screen. The upgraded ISP can also power the new camera module of the iPhone 14, which can achieve 4 trillion operations when taking pictures. Apple says this “drives a 4-in-1 pixel sensor for a vast creative space”.

In addition to the upgrade of the chip on the Pro model, the entire iPhone 14 series also supports the function of satellite communication with specific software in emergency situations. This feature is very similar to what was shown at the Huawei Mate 50 launch a few days ago.

In an emergency, iPhone 14 users can use beamforming, directional antenna arrays to connect to LEO satellites, and send Apple’s preset text messages to ground receiving stations. If necessary, the information will be forwarded to the ambulance center.

When using this function, the user is required to be in an open area where the sky can be seen. The software directs the user to point the phone in the direction of the satellite and establish communication. The speed at which the information is sent depends on the area where the user sends the information. The information can be sent in about 15 seconds in the open field, and it takes a few minutes at most when there are obstacles such as leaves.

At the press conference, Apple did not specify the technical details of the feature, and it was not clear which satellite network the communication satellites used came from.

Received a “stay put” response after the message was sent in the demo video, but it’s unclear if this means that the satellite communication technology on the iPhone 14 supports the ability to receive messages.

Apple said that the reason for using preset text is that the data transfer rate between the phone and the satellite is very low. Using preset text can reduce the amount of data transmitted by one-third through Apple’s short text compression algorithm.

The satellite communications service will be available to the first iPhone 14 users in the U.S. and Canada starting in November, and will be free for the next two years.

In addition, at this event, it was rumored that the new processors of the Mac Pro and M2 series that will be unveiled at the conference were absent. At the Apple Developer Conference in June 2020, Apple CEO Cook once promised to switch the Mac series product line to Apple’s self-developed chip platform within two years. Now that the deadline is approaching, it seems likely that Apple’s “silicon plan” will not be completed as scheduled.
