Nowadays, the competition in the smart phone chip market is becoming increasingly fierce. Every manufacturer is launching new products. Everyone claims that their products are excellent. How should we distinguish the advantages and disadvantages of smart phone chips and how to choose the products that suit them.
First, the secret of mobile phone chips
In addition to Apple, the mainstream smartphones are now mostly Android, and the software is basically homogenized. The running speed of the mobile phone, the corresponding time, the gaming experience, the communication speed, and even the Internet speed are directly related to the mobile phone chip. The mobile phone chip is not a single CPU, but a soc that integrates multiple parts.
First of all, there is a cpu inside the mobile phone chip, which is responsible for the main computing tasks. The running speed of the mobile phone is basically determined by the cpu. Now the cpu of the mobile phone is basically multi-core. In addition to Apple's insistence on dual core, it is basically four cores, eight cores, and ten cores.
It should be pointed out that the more the core, the faster the phone runs. For most tasks, the single core of the multi-core is the fastest speed, and in some programs that support multiple cores, the core number is more advantageous.
In addition to the cpu, the mobile phone processor also has gpu, gpu is mainly for the mobile phone 3d game preparation, gpu powerful, for the speed of the Internet to open the app does not make sense. But for mobile games, the strength of the gpu directly determines the speed and picture, directly affecting the experience.
In addition to CPU and GPU, most mobile phone processors now integrate baseband chips. The baseband chip is responsible for communication, and the baseband chip specification determines whether your mobile phone supports 2g, 3g, or 4g. The same is 4g, which determines your speed at that level. Of course, mobile communication is both sides, and the specifications are supported by the carrier's base station in addition to your mobile phone support.
In addition, the mobile phone chip also integrates coprocessor, memory control, video accelerator, image processor (ISP) and other parts. Each home is also different, but these things are not perceived by consumers because they use bottlenecks (the video accelerator supports more than the video format that users can find every day, and the number of pixels supported by the ISP far exceeds the pixels of the camera).
In addition to the chip's own specifications, the chip manufacturing process is also very important, the same design of the chip, the process is different, the chip's highest frequency, heat, power consumption is different, the more advanced the process. The better the performance of the mobile phone chip.
Therefore, for mobile phone chips, we mainly look at the CPU, GPU and baseband parts. In addition, for the actual products, we still need to see what process this chip is made of.
Second, which is the mainstream high-end chip?
Nowadays, there are several models of mainstream high-end chips on the market. Qualcomm's flagship processor is Snapdragon 820, while Snapdragon 652 and 650 perform well. Samsung's flagship is Exynos 8890; Huawei HiSili is Kirin 955, and MTK is X25.
Let's compare the specifications of these processors.
From the CPU point of view, the Snapdragon 820 is four big cores, the performance of a single core is not bad, and the ARM A72 is in the middle, the single core performance is top-level, and the multi-core performance is too small because the core number is too small.
And because the Snapdragon 820 has no small core, the power consumption will also suffer a little; on the GPU, the Snapdragon 820 adopts its own GPU core Adreno 530. This GPU has high specifications and the best performance; Qualcomm on the baseband Has always been a strong point, 4G download support to Cat.12, uplink support to Cat.13, the specification is one generation ahead of the competition, is the fastest.
In terms of craftsmanship, Xiaolong 820 uses the latest Samsung 14nm process, which is also top-level.
Looking at the Snapdragon 820 is still very good, but multi-core performance and power consumption are weak points.
Samsung's Exynos 8890 is an eight-core core with four high-performance M1 cores and four low-power A53 cores that switch to demand.
The single core performance is similar to the Snapdragon 820, but the multi-core performance wins by the core number, and because of the size of the core, the power consumption is ideal. On the GPU, Samsung was mad at the 12 GPU cores of the Mali T880, which was slightly behind the Snapdragon 820. Baseband Samsung and Snapdragon 820 basically the same specifications, the same 4G download support to Cat.12, uplink support to Cat.13. In terms of technology, Exynos 8890 is also the latest 14nm process.
Exynos 8890 and Snapdragon 820 strength between the secondary, CPU power and multi-core performance dominate, GPU is less.
Kirin 955 is also an eight core, but its four core is the public version of the A72, performance is not bad.
In terms of power consumption, plus the small core of four A53s, Kirin 955 power consumption is the most ideal; on the GPU, Kirin 955 only uses four Mali T880 GPU cores, although the frequency is raised, However, the actual performance is several times different from Qualcomm and Samsung; on the baseband, Huawei only supports Cat.6, and the competitors also have a generation difference.
In terms of technology, Huawei used TSMC's 16nm process, which is comparable to Samsung's 14nm.
The performance of Kirin 955 has a certain gap with Qualcomm and Samsung, but the power consumption control is ideal.
MTK's X25 is the only 10 core, three CPU cluster mobile phone processor, using two A72 big core, four high frequency A53 small core, four low frequency A53 small core combination, the advantage of this combination is work Consumption control can be more flexible, but performance will be weaker. On the GPU, the X25 and the Kirin 955 plugged four GPU cores of the Mali T880, which are also weaker grades. On the baseband, MTK also supports Cat.6, which is different from Qualcomm and Samsung.
The worst thing is that the MTK X25 uses a backward 20nm process, the frequency is difficult to pull up, and the power consumption is not too low.
In general, although the MTK X25 is known as the 10 core, the actual performance is the weakest, but this SOC is cheap, and LeEco even gives a low price of more than a thousand yuan, and the price is very high.
Third, how should consumers choose?
For consumers, it depends on specific needs. If you are looking for game performance, Qualcomm Snapdragon 820 is the best choice.
To pursue game performance, and also hope to control power consumption, Samsung Exynos 8890 is the best.
If you don't play games and have performance and power requirements, Huawei Kirin 955 is your best choice.
And to pursue cost-effective users, MTK X25 or even X20 is your best choice, now with several other chips are more than 2,000 yuan, while X25 and X20 machines are only more than 1,000 yuan. In particular, LeTV's ultra-low-priced products are worth buying.
The so-called poor performance of the X25 is in the new generation flagship. Compared with the last Snapdragon 810 and the low-end products of this generation, the X25 is still very good.
Mobile phone chip wars, consumers do not have to chase high, but should choose their own needs.
