Don't go to the physical store!
The price of the same notebook is often higher than that of online shops, and there are a large number of low-equipped notebooks in physical stores. Profiteers often sell these e-waste products to students who do not understand notebooks at high prices through deception and various semi-forced means.
If you don't buy notebooks in a physical store, where should you buy them?
When purchasing notebooks online, please try to buy them at the official brand store. If you buy them, you must identify the store.
I am personally accustomed to buying on JD.com, because the service attitude is better, It is easy to return and exchange and the express is reliable.
Hardware to pay attention to when buying a notebook:
Currently, Intel processor and AMD processor are main processor.
● CPU series: i9>i7>i5>i3 (no i9 and i3 on the notebook), note that this performance order is only true when compared to the same type of processor.
● CPU algebra: there is a bar behind i5 and i7, and the first number behind the bar is algebra. For example, i5-8300h is the eighth generation, and i5-7200u is the seventh generation. Be sure to buy the eighth generation! Compared with the seventh generation, the performance is greatly improved.
●CPU type: marked at the end of the CPU model, divided into low voltage version (U) and standard voltage version (H, 7 instead of HQ). Low pressure version of general performance, but less power consumption heating; Standard pressure version of good performance but more power consumption heating.
AMD processor:There are fewer notebooks. Be sure to buy the new Ryzen processor, and don't buy the A8, A10, and A12.
Mainly used for image processing, such as playing large games, clip video preview.
● Core video /Integrated Video Card: the video card is integrated in the CPU without independent video card, so it is not able to play large games, but it consumes less energy.
● independent video card: mainly produced by NVIDIA and AMD.
At present, most of the independent video card is produced by NVIDIA, so take N card as an example:
● MX150: an entry-level video card for thin and light notebook, with average performance.
● GTX series: games-level video cards.
Performance sequencing GTX1080 (trench specific) >GTX1070 (high-end game video card) >GTX1060 (good performance) >GTX1050Ti (common game video card).
8G is for common performance, and 16G is for high notebook performance.
There are mechanical hard disks (HDDS) and solid state drives (SSDS).
There must be solid state drives, which can read data much faster than mechanical hard drives. You can buy the type of solid + mechanical for large storage space requirements.
It is divided into IPS and TN screens according to the material. Be sure to buy an IPS screen!The resolution must be 1080.As for color gamut: the screen can display color range, 72%NTSC>, 45%NTSC. For students with high screen requirements (photoshop, etc.) try to buy high color gamut notebook.
So the question is, there may not be screen parameters on the current notebook sales page, so how to choose?
● If the merchant did not specify that it is IPS screen, then 99% is TN screen;
● If the merchant doesn't say the resolution is 1080, then 99% is low resolution.
● If the merchant does not specify a high color gamut screen, then 99% is the background gamut screen.
Before buying a notebook, you must first clarify your needs. At present, notebooks in the market can basically be divided into three categories: light notebook, game notebook and all-around notebook.
Light notebook: generally 13.3 or 14 inches, very light and thin, good battery life, with low-voltage processor, no independent video card or with entry-level video card, daily performance is enough, not good for playing large games.
Game notebook: 15.6 inches in general, standard pressure processor + gaming video card, strong performance, poor battery life, thicker and heavier.
All-around notebook: between the light notebook and the game notebook. The body is not too heavy and adopts an entry-level game card.
Following are some common problems in the selection and purchase of notebooks.
First, you should consider which generations they are, and are they standard pressure or low pressure?
In addition, even though these are the same, since the heat dissipation of the notebook is generally not very good, the i7 will tend to fall down so that the gap between i5 and i7 is reduced, and in many cases the i5 is more cost effective than i7.
To think about what you want. If it's just a daily use, or for playing the lol game, which requires less for the video card, it's perfectly adequate. And there's no such thing as an independent video card that you can't think about, because you don't have to think about the heat of the video card. The CPU will get a better release.
For quite some time now, AMD processors have been almost synonymous with profiteers, but with the launch of a new series of Ryzen CPUs, AMD processors have been able to match with those of Intel’s. However, its market share in the laptop market is still small. In the future, more and more notebooks should be equipped with AMD processors.
At present, the manufacturing technology of notebook is very mature, and it is not advanced technology. In addition, the designers of various manufacturers are also in flux. The components are purchased from the same companies, and the design is similar.
