The CPU, GPU, performance controller, neural network unit, and ISP inside the A11 biochip are all Apple-designed.
Self-designed CPU core: Six cores on the A10 chip, Apple introduced the so-called "Fusion" technology, the CPU uses a new four-core design, with two high-performance cores and two energy-efficient cores. Both high and low energy cores can achieve the desired performance and energy efficiency according to different needs.
Among them, the energy-efficient core is used to cope with intensive heavy tasks and improve processing speed to ensure performance. The energy-efficient core is used in daily affairs and low-energy operation to ensure the battery life is improved and enjoy a longer single-charge life.
With the latest A11 biochip, Apple has taken another step forward.
This time, the A11 bionic CPU uses a six-core design consisting of two high-performance cores and four energy-efficient cores. Compared to the A10 Fusion, two of the performance cores have a 25% increase in speed, and the four energy-efficient cores have increased speed by 70%, resulting in superior performance and energy efficiency.
The key is that Apple has also prepared a second-generation performance controller, so it can simultaneously play the full power of the six cores, with up to 70% performance improvement to cope with multi-threaded workloads.
For the performance of all six CPU cores, it is unclear how much improvement, but at least on the benchmark test, the current leaked scores are quite amazing.
Kirin 970The first integrated NPU of Huawei Kirin 970 adopts HiAI mobile computing architecture, and its AI performance density is much better than CPU and GPU. Compared to the core of four Cortex-A73 (the flagship CPU of mobile processor leader ARM last year), Kirin 970's new heterogeneous computing architecture has approximately 50 times energy efficiency and 25 times performance advantage when dealing with the same AI application tasks. . This means that the Kirin 970 chip can accomplish AI computing tasks with a higher energy efficiency ratio. For example, at an image recognition speed, it is possible to reach about 2000 sheets/minute.
Kirin 970 innovatively designed HiAI mobile computing architecture, using the most energy-efficient heterogeneous computing architecture to maximize the performance of CPU / GPU / ISP / DSP / NPU, while the first integrated NPU dedicated hardware processing unit, its acceleration performance and energy efficiency ratio is excellent For CPU and GPU.
A system-level mobile phone chip mainly includes CPU/GPU/DSP/ISP, and many components such as baseband chips. This time, the Kirin 970 still has an eight-core CPU built in, and there is no change compared with the previous generation Kirin 960. On the GPU, Kirin 970 uses the Mali-G72 architecture that ARM just released in May 2017. The performance is improved compared with the Mali-G71. In addition, in the core number, the GPU of the Kirin 970 is also 8 from the Kirin 960. The nuclear has increased to 12 cores.
On the baseband chip, Huawei has taken advantage of its position as a communications equipment manufacturer. Kirin 970 directly supports LTE (4G) Cat.18 (network speed rating) with a maximum speed of up to 1.2Gbps.
Although there is no particular surprise in the CPU and GPU, the overall performance will be improved due to the Kirin 970's 10nm process. Yu Chengdong said that the energy consumption ratio of Kirin 970 has increased by 20%.
éªé¾™835Qualcomm Snapdragon 835 chip is based on Samsung's 10nm manufacturing process. Compared with 14nm, the 10nm process will make the chip speed 27% faster and the efficiency increase 40%. The Qualcomm Snapdragon 835 chip area will become smaller.
In October 2016, Samsung announced that it has taken the lead in mass production of the 10 nm FinFET process in the industry. Compared to its predecessor's 14nm FinFET process, Samsung's 10nm process can reduce power consumption by up to 30% and achieve a 27% or up to 40% reduction in power consumption. By adopting a 10 nanometer FinFET process, the Snapdragon 835 processor will have a smaller chip size, allowing OEMs to get more space available in upcoming products to support larger batteries or thinner designs. The combination of process technology and more advanced chip design is expected to improve battery life.

Comparison of detailed performance parameters of three processors2017 is over, no surprise. Before 2018, major mobile phone chip makers will no longer have a heavy flagship chip release. In the first half of 2017, Xiaolong 835 took the lead and became the most mainstream flagship mobile phone chip. The Apple processor is a self-respect, and it is invincible in the fruit powder. Hai Si is more like a crouching ninja, watching the gap between himself and his opponent, seeking opportunities to give his opponent a fatal blow.
The calm of nearly half a year was broken in September. When the Apple Autumn Conference was held on September 13th, the Apple A11 chip came out as a second-second air, and the overall strength made the Android chip camp tremble. Yes, the A11 processor is too strong, and soon after the release, it occupied the top of the mobile CPU ladder list.
In October, it was not calm. As a representative of “China Coreâ€, Heis released its annual flagship chip, the Kirin 970. Hai Si seems to find a way to give opponents damage, that is AI. Kirin 970 became the world's first AI chip, leading the bionic chip Apple A11. The mobile phone CPU ladder diagram puts the Kirin 970 in second place, higher than the Xiaolong 835.
éªé¾™835
The Snapdragon 835, which has been arrogant for half a year, has become the third place. My heart is definitely not convinced: Where is it better than others?
In November 2016, Qualcomm released news that its next-generation flagship chip, the Snapdragon 835, has been mass-produced and will be available in early 2017. The Snapdragon 835 is based on the Samsung 10nm platform. The advanced technology makes the chip speed 27% faster and the efficiency increased by 40%. Of course, the chip size is further reduced.
Let's take a look at the configuration parameters of the Snapdragon 835:
The main frequency of the Snapdragon 835 chip is 1.9GHz+2.45GHz, with eight-core design, the size of the core is Kryo280 architecture, large core frequency of 2.45GHz, large core cluster with 2MB L2 Cache, small core frequency of 1.9GHz, small core The cluster has 1MB of L2 Cache and the GPU is Adreno 540. Compared with the previous generation, the performance is up to 25%. It supports 4K screen, UFS 2.1, dual camera and LPDDR4x four-channel memory, and integrates Cat.16 baseband.
The Snapdragon 835 processor supports Quick Charge 4 fast charging. Compared to Quick Charge 3.0, its charging speed is increased by 20% and charging efficiency is increased by 30%.
Compared to the Xiaolong 821, the Xiaolong 835 has been greatly enhanced in CPU, GPU, graphics API, ISP/DSP, memory bandwidth, baseband and fast charge modules.
Of course, this time the Snapdragon 835's opponent is not its own generation of flagship chip Snapdragon 821, but the competitor's latest flagship chip Kirin 970 and Apple A11. In the face of the latecomers, how is the performance of Xiaolong 835?
We first look at the running situation, this is the most intuitive performance of the mobile phone chip.

The Snapdragon 835 is the top player in the mobile CPU ladder list for more than half a year with its excellent multi-core capability.
A11 processor
After watching Xiaolong 835, we watched the second Apple A11 processor released. People who do mobile phone processor evaluations like to say a word: the processor is divided into two types, Apple and others. From this point, we can see that the Apple processor is powerful. Once Apple's latest processor is released, it must occupy the mobile CPU ladder list for a while, and the A11 processor is no exception.
The A11 processor is a processor chip independently developed by Apple. It adopts a 6-core design and consists of two high-performance cores code-named Monsoon and four low-power cores code-named Mistral. The A11 processor is a breakthrough in the history of Apple chips. The number of cores has reached six, which makes Apple, which has always been single-core performance, a new level of chip comprehensive capability.
Apple's A11 processor is exclusively manufactured by TSMC's 10nm platform. It is rumored that Apple has produced 100 million A11 chips in TSMC to cope with the strong demand of the new iPhone. At present, iPhone 8 shipments are not good, this batch of chips will be digested by iPhone X.
Let's take a look at the running scores of the Apple A11 processor.

A11 processor multi-core capability
Apple's multi-core running has been broken, and the single-core running score has reached an astonishing 4,200 points. The overall performance is indeed invincible.
From the running point of Ann Bunny, you can feel the power of the A11 processor more intuitively.

All the abilities are better than Snapdragon 835.
Kirin 970
Kirin 970 was placed in the second position by the mobile CPU rankings. This position is not good and requires a strong chip capability. The Kirin 970 chip is a new generation of chips from Huawei's 10nm process, which is the world's first smartphone AI computing platform with built-in independent NPU (Neural Network Unit).
The Kirin 970's first integrated NPU uses the HiAI mobile computing architecture, and its AI performance density is significantly better than CPU and GPU. Compared to the core of four Cortex-A73 (the flagship CPU of mobile processor leader ARM last year), Kirin 970's new heterogeneous computing architecture has approximately 50 times energy efficiency and 25 times performance advantage when dealing with the same AI application tasks. . This means that the Kirin 970 chip can accomplish AI computing tasks with a higher energy efficiency ratio. For example, at an image recognition speed, it is possible to reach about 2000 sheets/minute.
Kirin 970 innovatively designed HiAI mobile computing architecture, using the most energy-efficient heterogeneous computing architecture to maximize the performance of CPU / GPU / ISP / DSP / NPU, while the first integrated NPU dedicated hardware processing unit, its acceleration performance and energy efficiency ratio is excellent For CPU and GPU.
In the Antu Bunny and Geekbench4 running points, the Kirin 970 and the Xiaolong 835 were flat.

This kind of performance makes sense that the Kirin 970 should be at the same level as the Snapdragon 835, so why is it superior? The reason is the performance bonus brought by AI. Although Snapdragon 835 is consciously involved in AI, it is too far from the real AI. Remember the release of Huawei mate10? When Yu Chengdong demonstrated the image processing ability of Kirin 970, let us see that there is too much difference between Xiaolong 835.
Huawei mate10 conference demonstration PPT
Although Huawei mate10 also won Apple, but because the Apple A11 processor CPU capacity is too strong, this first position will be discussed later.
It can be seen from the data comparison of each running sub-platform that the ranking of the mobile phone CPU ladder diagram is still very reasonable. However, Qualcomm's release rhythm is clearly ahead of Apple and HiSilicon. At the beginning of 2018, the Snapdragon 845 will be released soon. The latest flagship chip based on 7nm may once again suppress all chips on this list for nearly a year.
