The CPU is the core processor of the computer, responsible for executing instructions and processing data, and its performance directly affects the operating speed of the device. The basic function of the CPU is to read instructions, perform calculations and output results. Key metrics include the number of cores, number of threads, main frequency, and cache size. 1. The more cores, the stronger the multi-task processing capability; 2. The more threads, the stronger the ability to process tasks at the same time; 3. The higher the main frequency, the faster the execution speed of a single task; 4. The larger the cache, the faster the data search speed. It is enough to use dual-core and four-threads in daily life, but the game is recommended to start with 6 cores, and video editing or 3D modeling requires more than 8 cores. Different scenarios have different CPU requirements, offices can be selected for entry-level, while mobile phones are commonly found in Qualcomm Snapdragon, Apple A series and other brands. Reasonable choice of CPU performance can avoid unnecessary expenses.

The full name of the CPU is a central processing unit (Central Processing Unit), which can be regarded as the "brain" of a computer. It is responsible for executing instructions in the program and processing data, and almost all calculations and operations are inseparable from it. Simply put, the stronger the CPU performance, the faster and smoother the device will run.

The basic role of the CPU

The core task of the CPU is to execute instructions. These instructions may come from operating systems, software or user operations, such as opening web pages, playing games, playing videos, etc.

• It reads instructions and data from memory
• Then perform calculations or logical judgments
• Finally, write the result back to memory or output to other devices

You can think of it as a super efficient factory administrator who constantly receives tasks, arranges processes, and deals with problems.

Several key indicators of CPU

If you have paid attention to the configuration when buying a computer or mobile phone, you may see some parameters, such as "4 cores and 8 threads", "main frequency 3.5GHz", etc. These are important indicators for measuring CPU performance.

• Number of cores : Multi-core CPUs work like multiple workers at the same time, which can significantly improve multi-tasking capabilities
• Number of threads : The more threads, the more tasks the CPU can handle at the same time.
• Main frequency : The higher the main frequency, the faster the individual task will be executed, and the unit is GHz
• Cache size : The larger the cache, the faster the CPU will find data, reducing waiting time

Generally, dual-core and four-threading are enough for daily use, but if you want to cut videos and play large-scale games, you need at least 4 cores or more.

CPU requirements in different scenarios

The CPU requirements vary greatly from different uses. To give a few examples you will understand:

• Office typing and Internet access : entry-level dual-core processors are sufficient, such as Intel Celeron or AMD A series
• Playing games : It is recommended to choose a mid-to-high-end CPU with 6 cores or more, such as Intel i5 or AMD Ryzen 5 to start with
• Video editing/3D modeling : This type of professional work pays more attention to multi-core performance, it is best to choose 8 cores or even more, such as i7/Ryzen 7 or above
• Mobile CPU : Although it is not called Intel or AMD, brands such as Qualcomm Snapdragon, Apple A-series, and MediaTek Dimensity also have obvious performance differences

So think clearly about the purpose before buying a device, and don’t blindly pursue top CPUs, otherwise it will be easy to waste money.

Basically that's it. After understanding what the CPU is and how it affects performance, you will have a clear idea of choosing a device in the future.
