Computers have long been a necessary intelligent device for office learning. In various scenes, there is one for each person. The existence of computers is indispensable in life. It will involve the purchase of computers. The update iteration speed of electronic products has been fast. In order to ensure the stability of their consumers, various brand manufacturers on the market introduce about two new computer models a year. This has a greater test for consumers’ purchase.

In fact, there are so many core components of the computer. We can make comparative choices. Combined with the latest evaluation data, it is not difficult to purchase the computer as imagined.

Processor CPU

CPU is similar to the human brain and can accept and process all the information of the whole computer. Its performance will affect and determine the use and running speed of laptops. At present, the mainstream CPU manufacturers in the market are Intel and AMD. If it is used in normal office scenarios, these mainstream CPU performances in the market can be supported. For users with game needs, the CPU requirements are high. The common processors in Intel include i5, i7 and i9. They are all different models of Intel Core series. AMD’s CPU name is similar to Intel’s,

so it will not be repeated here.

GPU Graphics Card

Graphics cards are used for graphics processing. People with high requirements for graphics display should pay more attention to the quality of graphics cards. It is divided into core graphics cards and discrete graphics cards. The latter has better performance indicators. However, the former can meet some daily use needs. At present, the mainstream graphics card manufacturers in the market include NVIDIA and AMD. The former is more common.

Hard Disk

Hard disks depend on the storage space size and reading and writing speed of computers. The larger the space, the faster the speed, which means better performance. There are two kinds of mechanical hard disks and solid-state hard disks on the market. Mechanical hard disks are cheap, large in capacity but slow in speed. Many computers on the market are a combination of solid-state hard disks and mechanical hard disks.The above three points are the most basic knowledge of laptops. These are the most basic issues to consider before purchasing products. There is the problem of cost performance that everyone is concerned about, which can only be specifically analyzed according to different product performances. However, under the current background, we can pay attention to the price differences in different regions. For example, the laptop price in UK and in US can be compared. This is more conducive to reasonable purchase.
