Calculation force of A13 neural network
today's computers are logic computers with poor perceptual thinking ability, and quantum computers are still far away
according to the current theory and engineering practice, no matter how large the scale of neural network algorithm is, whether you really want the robot to move a finger or write programs in C + + or other languages honestly
neural network is a kind of information processing algorithm in essence, and only programming can make robot proce behavior. At present, there is no theory to integrate the two, that is, we can't achieve the purpose of automatic programming through information processing, and we can't generate unpredictable information through programming. Without this foundation, we can only say that we haven't even touched it.

The strength of a series processor ensures that the new iPhone keeps ahead of the price and performance every year. This year's new machine is still a "repeat of the old technique". The iPhone 11 series is equipped with a new a13bionic processor and a neural network engine. Apple continues to focus on AR function and AI experience
a13bionic is equipped with a new artificial intelligence core, neuralengine. Apple said that the machine learning (ML) performance of the chip has been greatly improved, and the 8-core neural engine can perform 1 trillion operations per second, "bringing six times the performance upgrade.". AI performance is more powerful, without the need to let A13 processor "small material big use", to achieve better performance. Of course, with Apple's optimization, these improvements will be "silent" reflected in your daily experience
Big
The differences are as follows:
1, processor parameters. A13 processor is manufactured by 7Nm process and has 8.5 billion transistors; The A14 processor uses the instry's first 5nm process and integrates 11.8 billion transistors
2. A14 is 30% higher than A12. Based on 100 points, A13 scores 120 points, A14 scores 130 points, and a14gpu is 8% better than A13
3. Neural computing engine. A14 has been upgraded from 8-core to 16 core of A13, and AI computing capacity has been increased to 11.8 trillion times{rrrrrrr}
extended data
A14 processor adopts the latest 5 nm process SOC. Compared with A12 and A13 in 7Nm process, A14 processor has higher logic density, higher speed and lower power consumption. The A14 processor has a staggering 11.8 billion transistor combs, while the A13 processor has only 8.5 billion transistors and the A12 processor has only 6.9 billion transistors
secondly, the architecture design of A14 processor is basically unchanged, which is still a combination of six core CPU and four core GPU, in which the CPU contains two high-performance cores and four low-power cores
The improved neural network engine NPU is more intuitive. The number of 16 cores is doubled, and 110000 neural network operations can be performed per second. In short, the performance of AI has doubledWhat's the difference between Apple B14 processor and A14 processor

in terms of CPU and GPU performance, Apple's A14 and A12 processors have improved GPU performance by nearly 40% and 30% respectively. So far, it's a good upgrade
compared with A14 processor and A13 processor, CPU and GPU are increased by 16.7% and 8.3% respectively, with larger CPU improvement and smaller GPU improvement
B14 processor is actually the lock screen version of A14 processor. Due to the 5nm process of TSMC, Apple had to shield part of the core, resulting in performance degradation
therefore, both A14 and B14 are chips with 5nm process. However, A14 is more powerful without frequency locking in terms of performance
however, the performance of B14 processor has been reced by apple for some reasons. The performance will be slightly worse, but there are still many improvements.
2. A13 bionic chip adopts 64 bit fusion architecture, the performance core handles complex tasks at a faster speed, and the special energy efficiency core is responsible for daily tasks. This design significantly improves the battery life
3. A13 is a six core processor. The CPU part is also composed of two large cores and four small cores. The speed of two performance cores can be increased by 20%, and the energy consumption can be reced by 30%. The speed of four energy efficiency cores can be increased by 20%, and the energy consumption can be reced by 25%
4. For the GPU part, apple said that it has optimized the metal framework and has four cores, with 20% performance improvement and 40% lower power consumption than the previous generation; Equipped with eight neural network engines, you can understand NPU and other things. Compared with the previous generation, its performance has been improved by 20% and its energy consumption has been reced by 15%.

3. Network: the three new procts of iPhone 11 series all support al sim card and al standby, support nano SIM card, and are not compatible with the existing micro SIM card. According to the introction, users can select data and voice SIM cards in the settings. The use of al cards requires the use of two mobile communication services (which may include restrictions on roaming). It is not supported to use two CDMA mobile communication services at the same time. Only some operators support al volte. Specific restrictions are to be observed
The highlights of iPhone 11 are: rich color matching, al camera system, superior performance and good enrance. This time, the iPhone 11 not only changed its shell, but also added a new imaging system, intelligent HDR, night photography, deep fusion and other apple black technology blessings, which made up for the shortcomings in photography
1. Rich color matching
the most intuitive feeling of a mobile phone is its overall color matching and mobile phone materials. As the successor of XR, this mobile phone continues the colorful design in color. In addition to the classic black, white, yellow and red color matching, it also adds light green and light purple color matching, which gives us more choices from the choice
the design of the material is still very good, and the integrated double ion exchange process glass is used in the overall material, which not only increases the firmness, but also better encapsulates the process, making the waterproof performance more brilliant
2. Dual camera system
this time, iPhone 11 really surprised us in the innovation of camera. This time, the camera design adopts a new al camera system. A standard lens and an ultra wide angle lens both use a new sensor of 12 million pixels. The design of the details is really refreshing
