What are the limitations of mobile phones compared to desktop computers?

The differences between a mobile phone and a computer are:

1. Different sizes: intuitive, small mobile phones and large computers. In terms of memory, there are actually very few things that can be stored on a mobile phone, while a computer can store a lot of things.

2. Power consumption is different: due to the small size of the mobile phone, the power consumed is very small. The computer is large and has many programs to execute. The more power is consumed.

3. Different network configurations: mobile phones can access the Internet without broadband connection, while computers need to be equipped with network cards and routers to access the Internet.

4. There is also a difference between the two in terms of games: if a computer game wants to attract players, the sense of control of the game and the impact of the picture are the two core elements. However, mobile games are restricted by the hardware of mobile phones themselves, and they cannot be compared with computer games in these two aspects, which is the biggest obstacle to the development of mobile games.

5. Different operation methods: the computer keyboard is operated with both hands, which can give gamers full operation skills and freedom, while the mobile phone is limited by the size of the keyboard, and is generally operated with one hand, and it is impossible to set up complex operation techniques, which is naturally difficult to provide players with fun in terms of operation skills.

In fact, smartphones and computers are still not comparable for the time being, and they are both irreplaceable.

For the same amount of money, the performance of the computer must surpass that of the mobile phone, especially the desktop, and the mobile phone is completely incomparable to the graphics card alone.

However, mobile phones are much more convenient than computers because they are much more convenient than computers.

In essence, there is no big difference between the two, and the future trend will definitely be one, and finally it is the smart terminal.

The screen can't be as big as 27 inches.

How big is the gap between a computer CPU and a mobile phone CPU? Objectively speaking, there is no comparison between computer CPUs and mobile phone CPUs, because they run on different platforms, which is like comparing two different industries, there is nothing substantial. Of course, if you insist on comparison, you can squeeze out something.

1. The architecture of computer CPU is different from that of mobile phone CPU.

The CPU, whether it is Intel or AMD, uses the Intel x86 architecture; The mobile phone CPU uses the British ARM architecture. There is a big difference between the two chip architectures, the x86 architecture focuses more on CPU performance, while the ARM architecture focuses more on low power consumption. Because the heat dissipation space of the computer is relatively large, the CPU of the x86 architecture does not need to worry too much about heat dissipation, so the focus is on the performance of the chip and the pursuit of faster computing.

The CPU of the ARM architecture has more problems to consider, because the mobile phone has a small space and poor heat dissipation, so it is necessary to find a way to reduce the power consumption of the chip, and at the same time, it is necessary to improve the computing power of the chip.

Second, the integration degree of computer CPU and mobile phone CPU is different.

In terms of integration, there is a big difference between a computer CPU and a mobile phone CPU. To be precise, the mobile phone CPU should be called the mobile phone SOC, the full name is System on Chip, Chinese means system-on-chip. The mobile phone SoC integrates a series of functional modules such as CPU, GPU, RAM running memory, MODOM, navigation and positioning, and mobile phone baseband (the following figure is a schematic design diagram of the Kirin 990 chip).

The computer CPU is not so complicated, it is a simple ** processor, there is no integration of other functional modules, the memory in the computer, graphics processor (graphics card), network interface are independent. Computers also have integrated graphics, but not in the CPU, but on the northbridge chip on the computer's motherboard.

Third, the computer CPU far surpasses the mobile phone CPU in terms of performance.

Due to the different architectures and integration levels, the computer CPU is N levels stronger than the mobile phone CPU in terms of computing power. Today's mobile phone CPUs and computer CPUs are almost the same in terms of process, both of which are manufactured using 7nm processes, and when the volume is the same, the internal transistors of the two CPUs are not much different. However, the volume of the computer CPU is much larger than that of the mobile phone CPU, and there are no other modules integrated inside, so it is more concentrated; The mobile phone CPU is smaller, and there are a lot of other modules integrated in it, which is more attentive, and the real CPU module is not large (as shown in the red of the above picture is the CPU module of the Kirin 990 chip SoC), so it is far behind the computer CPU in terms of overall computing power.

From the above comparison, we can see that computer CPUs and mobile phone CPUs are very different, each with its own advantages. There is a specialization in the art industry, which is not only for our profession, but also for computer CPUs and mobile phone CPUs.
