How to choose a computer when buying one?

Purchasing a computer is a complex task that requires consideration of multiple factors such as purpose, budget, and performance requirements. In this article, PHP editor Youzi will delve into the key factors that influence computer buying decisions, from processor type to storage capacity, to provide you with a comprehensive guide. This article will help you identify your needs, make an informed decision, and choose the computer that best suits your purposes.

1.

Determine the budget and needs

The prerequisite for purchasing a computer is to choose based on the budget, from the following three levels Budget to choose.

1. The first choice for low-end office users below 3,000 yuan.

2. 3000-5000 mid-range business users.

3. More than 5,000, high configuration experience, game players.

After knowing the budget, you must make an in-depth selection based on your own needs, that is, the purpose, and be clear about the main purpose of the computer you buy in the future. This will avoid over-configuration or failure to meet your needs.

Look at the configuration

You need to know the basic configuration before buying a computer.

CPU processor: The two mainstream manufacturers of CPUs are Intel and AMD.

1) Intel processor

CPU series: the most common Core series i9, i7, i5, i3, the performance is i9>i7>i5>i3 (only for the same generation and type processor comparison).

CPU generation: Represents which generation of CPU. Generally speaking, the larger the number, the better the performance. For example, i5-9300H is the ninth generation and i5-7200U is the seventh generation.

CPU type: divided into low voltage and standard voltage, marked on the suffix of the CPU model. Y and U represent low voltage, H, M, Q, and X represent standard voltage. Standard voltage CPU: has strong performance, high power consumption, high heat, and short battery life. Low-voltage CPU: low power consumption, low heat production, slightly poor performance, and long battery life.

2) AMD processor Ryzen series: Like Intel Core, it is divided into low-voltage and standard-voltage versions. The latest low-voltage version models are R5 3500U and R7 3700U, and the standard-voltage versions are R5 3550H and R73750H. Among them, the low-voltage Ryzen is at the same level as the low-voltage Core, and the standard-voltage version is slightly inferior to the Core.

Look at the configuration:

Graphics card: mainly handles graphics, divided into nuclear graphics/integrated graphics and independent graphics.

1) Integrated graphics/Integrated graphics

The integrated graphics card is welded to the motherboard, while the core graphics coexists with the CPU, with better performance and lower power consumption than integrated graphics.

2) Independent graphics

Independent graphics comes with its own independent video memory and does not occupy system memory. The current mainstream manufacturers are NVIDIA and AMD.

NVIDIA:

The performance of the 20 series from high to low is: GeForce RTX 2080Ti/2080/2070/2060

The performance of the 16 series from high to low is: GeForce RTX 1660Ti/1660/1650

10 series performance from high to low is: GeForce RTX 1080Ti/1080/1070Ti/1070/1060/1050

AMD:

Radeon RX Vega Series: Radeon RX Vega 64/56

Radeon RX 500 Series: Radeon RX 590/580/570/560XT/560/550

Radeon RX 400 Series: Radeon RX 480/470 /460

Memory

is used to temporarily store the calculation data in the CPU, which is the icing on the cake. The current computer memory is basically 4G or more. If you want to make the computer run faster, it is recommended to have 8G or more. However, in the case of excess configuration, you still have to choose the memory according to your own needs. It is not necessary.

5.

Hard disks

are basically divided into mechanical and solid-state. Mechanical has large space, slow transmission, and cheap price. On the contrary, solid-state has small space, fast transmission, and high price. There is nothing much to say about the hard drive. Conditions allow the solid state to be used as a system disk and a mechanical storage device to store data. However, current computers using solid state can meet the needs of basic users.

6.

Screen

If you feel comfortable using a computer, you should look at the screen. Please note the following when looking at the screen configuration:

1) Although there are IPS and TN screens, it is recommended to choose IPS!

2) The current mainstream resolution is 1080P or above.

3) Color gamut: The range of colors that can be displayed on the screen, 100%sRGB≈72%NTSC>45%NTSC. For design requirements, try to choose a high color gamut screen.
