College students should consider the performance of CPU, graphics card, screen and hard disk when choosing notebook computers.
1、CPU .
CPU is the core of a notebook computer, and its performance will directly determine the extreme computing power of this notebook computer. Of course, it is enough for the mainstream CPU in daily office, but it is very important to have a powerful CPU for rendering /3D drawing, video editing and simulation operation.
2. Graphics card.
A graphics card is firmware that processes images and outputs them to a monitor. At present, the graphics cards in notebook computers, whether nuclear display or stand-alone display, have the functions of 3D acceleration and image processing. The core graphics card is common in thin and light notebooks, with low power consumption and slightly weak performance, but it can meet the daily office use.
The performance of discrete graphics cards is stronger than that of core graphics cards, but the corresponding power consumption and heat generation are also greater, which is more common in game books or high-performance all-around books.
3. screen.
The quality of the screen directly affects how your eyes look at it, so a good screen can obviously improve the comfort of daily use. The screen with good normal use experience only needs to meet the color gamut coverage of 100%sRGB. Consumers who have high demand for color can also choose screens with color gamut coverage of 100%DCI P3 and 100%AdobeRGB.
Users with high experience requirements can choose a high refresh rate to refresh the screen. The refresh rate of common screens is 60Hz. In order to give consideration to battery life, thin and light books often use a screen with a refresh rate of 90Hz/ 120Hz, while game books generally use a refresh rate of 144Hz, 165Hz and 300Hz. The higher the refresh rate of the screen, the more pictures are displayed per second.
At present, high-end game books experience excellent screens with a resolution of 2K/2.5K and a refresh rate of 165Hz. Special reminder is to be wary of low color gamut and high refresh screen, which is very common in low-priced game books.
4. hard disk.
Hard disk is the place where data is stored on a notebook computer. The two parameters that need attention are capacity and reading and writing speed. The capacity of the hard disk determines how many files, photos and videos your laptop can store, and the speed of the hard disk determines the fluency of turning on and off, loading software and overall use.
The game book generally has a stable position, and the demand can be increased by itself. If there is only one interface, you need to choose carefully. After all, it is difficult for users to replace the original solid state, reinstall or migrate the system when they want to upgrade.
