The past two days, Sjonny Sloki, senior vice president of Apple hardware technology (Johny Srouji) at the end of the conference, when interviewed by the media said that Apple will develop 3 years ahead of the beginning of a chip, 3 years ago published equipped with A8 chip iPhone 6, Apple has been in the development of A11 bionic chip, however, about AI the topic of machine learning and three years ago, the mobile industry is not enough.

Three years later, Apple's latest generation of flagship smartphone iPhone 8, iPhone 8 Plus and iPhone X (iPhone 10), are equipped with a new mobile chip A11 bionic. Thanks to the self-designed GPU graphics processing unit and the unlimited potential of the neural network engine, as well as a series of unprecedented high degree of customization unit, Apple said A11 bionic iPhone is the most powerful, the most intelligent chip.

A few days ago, from Geekbench 4 unofficial A11 bionic chip benchmarks show that Apple has a fast chip behind the scenes, whether it is but the average score or multi-core run points, are spike all mobile phone industry with ARM-based design Mobile processor. The key is, compared to the x86 platform 2017 MacBook Pro, this equipped with 3.1 GHz Intel Core i5 processor A11 did not have to admit defeat. As shown below:

Run to verify A11 CPU performance explosion, strong no opponent

Recently, the real from Geekbench new official run points finally baked, the results show A11 bionic performance even higher than the leaked data even higher. Among them, iPhone 8 A11 single-core achievement reached 4203 points, multi-core test run points up to 10065 points.


In contrast, as one of the best Android flagship smartphone benchmarks this year, Galaxy S8 single-core score of only 1965 points and multi-core and only 6494 points, compared with the A11 chip is indeed a huge difference. In fact, this score should be seen as with the last year's iPhone 7 series flagship competition, rather than the latest iPhone 8 series, and Apple's advantage can be extended to next year.


At the same time, from the above run we can see that the same is equipped with A11 bionic chip, Apple iPhone 8 and iPhone 8 Plus Geekbench score higher than the iPhone X, single-core difference is almost negligible, but multi-core About 7% or so. The reason why there are differences, conventional speculation that most of this and the screen resolution and memory size have a certain relationship.

In addition, according to Apple's official statement, A11 bionic CPU uses a six-core design, composed of two high-performance core and four energy-efficient core, compared to A10 Fusion, two of the performance core speed increased by 25%. We through the Geekbench score compared to iPhone 7 and iPhone 8, A11 compared to the A10 is indeed as Apple said, single-core speed of 25% faster, but the multi-core upgrade is quite amazing, the speed increased by 80%.

Of course, A11 bionic enough Almighty This is no doubt, but Geekbench is mainly for CPU performance testing, A11 bionic chip provides a new neural network engine, self-designed GPU, camera ISP image signal processing unit and other units, these features The module is naturally not within the scope of the Geekbench benchmark.

This time the latest from Geekbench official data, once again confirmed the A11 bionic chip strong, at least in the CPU performance than all the current Android flagship smartphone ARM chip. And this is the expected thing, because in recent years before the Apple A series chips are doing the same thing, especially in the single-core performance on the invincible, even two years ago, A9 single-core performance is still defeated this year All the flagship of Android.

Again compared 2017 13-inch MacBook Pro, found A11 score A11 can be comparable shoulder Kaby Lake Core i5, single nuclear close, multi-core or even higher. But it should be noted that a lot of performance conversion tasks can be achieved on the MacBook Pro, but these can not be applied to the smart phone. For example, MacBook Pro can drive a larger, higher resolution external TV, and perform the appropriate task on top, while the iPhone can not.

Some of the things outside the chip

As we all know, higher resolution means dealing with more pixels. This is also why the iPhone SE A9 chip (single core 2394, multi-core 4083) performance can still beat the new Android flagship phone one of the reasons, after all, the lower resolution of the total pixels less. Most of the flagship Android has been in the pursuit of ultra-high resolution display, especially Samsung, long-term development of their own screen as a major selling point, but the higher the resolution of the same performance performance of the chip will be more obvious.

In contrast, Apple is not eager to carry high-pixel iPhone display, but starting from the mobile SoC chip, through the efforts to develop chips to meet the existing high-resolution display needs. And for the display selection, Apple is considered by the resolution of other qualitative factors, such as color accuracy and color range and so on.

Since the 3 years before the launch of iPhone 6 and iPhone Plus 6, apple hasn't changed the next new iPhone resolution. Only in the iPad direction is different, through the development of apple with more GPU graphics performance "AX" series chip (such as A8X, A9X and A10X) to enhance the resolution of balance, after all, in recent years, the new iPad and iPad Pro these models to screen resolution is much higher than the iPhone.

A few years ago, I believe many people noticed that the screen with high resolution iPhone 6 Plus, is smaller iPhone 6 beat in the running, so in actual use. Because of its more screen pixel, probably around 2 million, equivalent to two times the iPhone 6/7/8. The Plus model has is the original pixel 3x rendering, and then perform 1.15 times zoom, it just is displayed on the screen of 1920 x 1080 pixels.

Apple's new iPhone X to do the adjustment, as with the Plus model, the pixel will do 3x rendering, but now is the perfect presentation of 3x resolution, which is apple said super retina (Super Retina) levels of 2436 x 1125 pixels. The total pixel is more than 2 million 700 thousand, almost three times the pixels of iPhone 6 /7/8 no, zoom. So high resolution, Apple will improve the performance of A Series graphics chip, which is based on improved AX chip before accumulation, only to meet the iPhone X high resolution screen drive demand.

In contrast, many of the blind pursuit of resolution Android manufacturers, such as Samsung Galaxy S8 provides high 4 million 200 thousand pixel screen. However, there is no and the pixels that match the performance of the chip come out, so in the actual performance, S8 is the flagship machine with a resolution of 1080p almost only, including HUAWEI the resolution is lower and the millet flagship mobile phone, after all chips can meet both.

A series of chip advantage from the world-class chip team

Now in the mobile field, custom chip manufacturers a lot, including Samsung, Huawei and millet, these are Apple's competitors. However, the gap between these competitors and Apple is still not small. Take Samsung, as early as 2010, Apple and Samsung chips are still close cooperation, Samsung has its own chip factory, and Apple's first launch of customized A4 chip before Samsung has been in the field of mobile research has many years of experience in the chip The.

However, in the past seven years, all this has undergone enormous changes, for the chip research and development of Apple invested a lot of money, special components of a world-class chip team, and very dedicated to energy efficiency, and will not sacrifice performance in exchange for The In all efforts, every year Apple developed A series of chips, can be more than 200 million shipments in the iPhone service. Not only that, Apple also extended more applications for different devices, including S series chips, T series chips and W series chips.

By contrast, Samsung and other manufacturers have all custom chips, while custom chip, still can not get rid of dependence on traditional chip suppliers. For example, Samsung, although the design of Exynos series chip, but the main use of the flagship machine or Qualcomm's Snapdragon chip, HUAWEI also started in recent years to meet the demand of the custom chip. However, these have custom chip mobile phone manufacturers, actual custom chip shipments of products based on the scale, still much smaller than apple.

Of course, all this is related to the size of the company, Apple through high-end mobile devices to earn the industry's highest profits, to scale long-term maintenance of chip research and development, and into the core technology patents. In contrast, most of the other competitors can not afford the chip technology research and development costs, do not have the necessary resources to develop custom chips, not to mention the most advanced, most outstanding chip, and most OEM manufacturers can only buy directly from Qualcomm solution.

And this time, Apple in the A11 bionic chip which, and further also introduced a self-designed GPU, from custom CPU to independent GPU, an independent chip complexity far more than all the OEM manufacturers so far, no doubt once again widened The gap with these competitors. It is difficult to imagine the next Apple will also design which key core components, taking into account the custom chip as Apple's long-term one of the important strategy, will help to maintain its continued dominance in the move.

Having said that, what is the use of running high customization?

I believe many people will ask such a question, after all, there are too many people into the domestic and international competition test start speed test. It should be noted here that the performance of the same period of the chip, naturally do not expect the great difference between the application experience. But with the A11 performance gradually widened the gap, coupled with a large number of custom features, the same application will be increasingly difficult to port to the Android platform.

In short, this gap will lead to the same situation: the same focus on performance and functionality of the app, iPhone running very smooth, rich for the function of custom hardware, and Android can not maintain the same efficient operation, but no custom function.

As the two day of the interview, the Apple Corp marketing senior vice president Phil Schiller, and senior vice president of Apple hardware technology Sjonny Sloki mentioned, if not a crazy behind A11, dedicated chip development team, perhaps it is just a chip not worth mentioning.

Among them, Siloki said: "We started doing this thing 10 years ago, the design of our own chip, which is Apple's hardware and software is particularly optimized to achieve the best way to truly custom. This is not your casual Want to do something. "

"Now we are on a very clear path of development," said Schiller. "One of the core elements of each generation will be its built-in chip, which, for us, is essentially an important component of product definition section."
