On September 10, 2019, Apple released a new iPhone 11 series. In the face of doubts from the outside world and the pursuit of Android manufacturers, how will Apple fight the enemy? The answer is: A13 Bionic chip.
To make it clear A13 must first go back to the A11 period of "redefining smart phones". In 2017, Apple released the iPhone 10th anniversary commemorative model-iPhoneX. The new technology of iPhone X, including face ID, Neural Engine, portrait mode, etc. showed Apple's definition of future mobile phones: mobile computing platform. In other words, Apple essentially changed Jobs's basic definition of iPhone.
Apple redefines the iPhone as a mobile data hub with communication modules, including linkage with other devices, primary data processing, and mobile carriers for AR, VR and machine learning. Therefore, Apple has successively released three generations of bionic processors to improve the computing power of the iPhone through radical innovation year by year, and introduce the Pro concept to the iPhone to realize Apple's vision for the future mobile computing platform.
A13 process
A13 Bionic uses TSMC’s latest 7nm DUV Performance-enhance version process (also called the second-generation 7nm DUV), which is 7% or 10 higher than 7nm DUV performance % Power saving effect.
Huawei Kirin 990 5G uses a 7nm EUV process that is more advanced than the second-generation 7nm DUV, which can reach 1.2 times the density of 7nm transistors, which is 10% or 15% higher than the 7nm DUV performance.
But at this node in September 2019, 7nm EUV did not achieve mass production, so Apple chose the second-generation 7nm DUV, and Huawei’s 7nm EUV can only be launched in November. Therefore, the A14 made by the 5nm EUV process will have more process bonuses than the 990 5G (span of a generation and a half process).
Under the background that this year's Huawei 990 5G still cannot reach A13 in terms of traditional performance, the performance difference between 1000 and A14 next year is likely to increase.
Performance
The basic performance improvement is the most boring part, but I still mention it.
The second-generation 7nm process brings a 20% increase in CPU performance, and a 20% increase in performance of GPU and neural network engine. The measured Geekbench4 single-core 5480 points, multi-core 13,951 points, which are 16% and 27% higher than the A12. Energy consumption has also been reduced. According to the official website, the energy consumption of large CPU cores is reduced by 30%, small cores are reduced by 40%, and GPUs are reduced by 40%. Still the most powerful mobile processor on the surface.
With the deep integration function provided by A13, more powerful camera and detail processing capabilities
More powerful innovation in addition to basic performance
New ISP The four cameras brought are fully open and it can simultaneously shoot 4K60fps video. The matrix calculation unit similar to the Qualcomm 855AI unit and the new fourth-generation performance manager can simultaneously perform machine learning, which is doubled (but compared to the 855, A13 has an npu).
The fourth-generation performance manager, there is no problem in hitting Android manufacturers for two years. It is not only a CPU performance controller, but can control the frequency of all A13 computing units and the on-off state of each unit. Therefore, it can intelligently adjust the output of computing power to ensure that the load task is completed with the lowest power consumption, which can greatly improve the battery life. At a battery level of 3969 mAh, it has reached the endurance of 4500 mAh by other manufacturers.
AppleThe unique combination of hardware and software brings more new functions.
Stronger machine learning ability brings Deep Fusion deep fusion function, second-generation Smart HDR and night scene mode function. While maintaining the traditional camera size (1/2.55), it has achieved at least the same level of camera capability as Huawei (1/1.6) with stronger hardware configuration.
Therefore, it can be said that 80% of the new features of iPhone 11 are brought by A13, which is truly "innovative." Apple is more stable than anyone else in realizing its product ideas, and more determined than anyone else.
