How big is the gap between computer CPU and mobile CPU?

At present, popular mobile phones in the market are equipped with Soc, such as Qualcomm Snapdragon, Huawei Kirin, Apple A series, Mediatek series, Samsung series and so on. Mobile Soc includes CPU, GPU, NPU, ISP, FPGA, baseband and so on. The CPU architecture of computer is different from the Soc architecture of mobile phone. The BASIC architecture of computer is X86, which consists of CPU, Northbridge chip, Southbridge chip, memory, graphics card, display interface, network card, sound card, serial advanced technology accessories, hard disk, and bus. Most of the current PC architectures are Intel's X86 architecture, which has contributed to Intel's dominance in PC chips today.

The mobile processor architecture is mainly based on the ARM architecture, which is a 32-bit compact instruction set (RISC) processor architecture, which is widely used in many embedded system designs. Due to its energy-saving characteristics, ARM processor is very suitable for the field of mobile communication, in line with its main design goal of low power consumption characteristics. The processors are based on the ARM architecture, which accounts for 75% of all 32-bit embedded processors and is one of the largest 32-bit architectures in the world. ARM processors are mainly used in portable devices, such as smart phones, handheld game consoles, and multimedia players.

How big is the gap between computer CPU and mobile CPU?Computer CPU is much stronger than mobile CPU in terms of performance and calculation speed. Currently, mobile CPU has reached 5nm process, such as Snapdragon 888, Kylin 9000 and Apple A14, all using TSMC's 5nm process, and the number of transistors has reached tens of billions. Intel's latest cpus currently use a 10nm process, which has lagged behind mobile chips. Currently, the latest Version of Snapdragon 888 has a running score of more than 740,000. Although snapdragon 888 mobile phone chip is very powerful in terms of data, its comprehensive performance is still not comparable with that of computer CPU.

Computer CPU has been monopolized by Intel for nearly 30 years, while operating system has been monopolized by Microsoft. The alliance between the two sides has formed incomparable advantages, also formed a huge customer base, and solidified the use habits of many users. As a result of Intel CPU monopoly, has formed a unified standard of hardware and software, basically all Intel CPU can use Microsoft system and now popular almost all tools software, so Intel CPU has strong compatibility.

And mobile phone chips, qualcomm Snapdragon, Apple A series, Huawei Kirin, Mediatek and so on jointly hold the market. There are two kinds of mobile phone systems, Android and iOS, as well as MIUI and EMUI, which are deeply customized based on Android. Therefore, the compatibility is far less than the COMPUTER CPU. Today's smart phones basically have no expansion ability, in addition to SIM card slot, other locations simply can not install memory card, with the development of science and technology, smart phones even SIM card slot disappeared, its expansion ability is basically zero.

Computer CPU development route is performance + speed. The speed of the computer from the original several M development to now is just a few G, and still a few cores, its speed and performance has been improved thousands, thousands of times, but the power consumption of the COMPUTER CPU is very large, the power consumption of the desktop is often able to reach hundreds of watts, even light thin notebook has dozens of watts of power consumption. The power consumption of mobile phones is much lower, requiring only a few thousand mAh battery to last a day. Because the ARM architecture is a compact instruction set, it itself takes into account the characteristics of low power consumption. In order to reduce power consumption, vendors put CPUS, Gpus, NPU, ISP, FPGA, baseband, etc., together, the size is only the size of a fingernail.

Overall, today's top-of-the-line mobile cpus are comparable to mid-range desktop cpus of at least 4-5 years ago, and because they are smaller and require controlled heat and power consumption, they are nothing compared to current laptop and desktop cpus.
