Method of purchasing basic hardware processor of notebook computer
It is recommended to choose a processor whose name Intel starts with i3, i5 and i7. AMD's a 10 and fx processors can reach the level of i3 and i5, but it should be noted that they will only appear in notebooks with a price of 3,000 yuan. The current processors i3, i5 and i7 are all the sixth generation (the numbers after i3/i5/i7 indicate which generation, for example, i7-6700HQ is the sixth generation processor). The fifth generation has good performance and the sixth generation has weak performance, but the heating power consumption is low. In addition, the four generations of CPU machines are old models, so please choose carefully. The rest of the processors not mentioned are carefully selected. Memory and hard disk memory are at least 4G, which can be replaced or added. Sometimes adding a piece of memory can bring qualitative change to the notebook. Hard disk can be divided into mechanical hard disk and solid state hard disk. The mechanical hard disk has a large capacity, but the data transmission speed is slow. Solid-state hard disk can transmit data quickly, but its capacity is small and its price is expensive. Of course, if you find that the notebook is not suitable, you can upgrade it yourself, but you need to pay attention to the problem of expanding the interface.
Graphics cards are generally divided into integrated graphics cards and discrete graphics cards. The integrated graphics card is integrated in the processor, and its performance is weak. Discrete graphics cards vary according to specifications, but overall they are better than integrated graphics cards, and of course the price will be higher accordingly. Generally speaking, it is enough to integrate the graphics card, watch videos, read documents and finish homework. If you like playing games, you can consider a discrete graphics card. There are two main manufacturers of graphics cards, one is NVIDIA and the other is AMD. Nvidia's entry levels are gt920m, gt820m, gt930m, gt830m, gt940m and gt840m, and it can run many online games that don't flaunt image quality. The mainstream levels are gtx950m, gtx850m, gtx960m and gtx860m, which can run almost all online games and most of the latest masterpieces with good picture quality. There are gtx970m and gtx980m fever levels, and almost all games can be played at will. AMD is an entry-level graphics card. In addition, the professional graphics card is mentioned. Students with professional needs can consider it as appropriate. Of course, the price is very expensive, and if you don't use the corresponding software often, there is no need to buy a notebook for this type of workstation. Also note that the graphics card is only marked? 2G memory? Or? High performance graphics card? All machines may be used by businesses to kill people, so choose carefully.
Other hardware here can refer to screen resolution, speaker, keyboard feel, weight, size, heat dissipation, etc., but it still depends on everyone's own measurement. More importantly, the following aspects:
(1) Resolution: The popular resolutions are1366 * 768 (13-14 inch) to 1080p( 15.6 inch). (2) Heat dissipation is an important part of notebook. After all, the computer is too hot, the computer will reduce the frequency, so the performance will be reduced. At the same time, due to poor heat dissipation, hardware is prone to aging. Heat dissipation needs to be queried online. After all, every notebook has a different design. (3) Weight. If you are a game expert, please choose a notebook with a screen of 15 inch or more. If you meet certain performance and portability, please choose 14 or 13 inch. If you want to take it out for study often, please choose a notebook with a screen of no more than 12 inch (of course, this kind of computer is too cheap and its performance will be poor. The suggested price is at least 5,000 inches. (4) warranty. The convenient warranty point near Beihang University is Lenovo's site. Opposite Zhizhen Building, computers of other big brands can at least guarantee a maintenance point near Zhongguancun, and it is also convenient to take the subway or bus. (5) Others, such as the feel of the keyboard, whether it is a backlit keyboard or not, and whether there is fingerprint recognition, depend on personal needs. Buying a computer in a physical store or an online store is confusing for many people. The physical store can let us actually get in touch with the notebook and further understand its various performances. But now most physical stores want to kill people, so everyone must pay attention to doing their homework when they go to physical stores. Generally speaking, computers with the same configuration can be bought at the price given by JD.COM Mall, and it is possible to bargain. Therefore, it is recommended to go to an officially authorized physical store to buy after doing your homework. For notebooks with a rough grade of 3000+ to 4000+, you can buy a large screen of i5+ or a small screen of i7+, computers of major brands, and graphics cards of GT 820m-GT 840m and GT 920m-GT 940m. These computers can be used. 5000+ level, you can buy a notebook with i7 processor or i5 processor, gtx850m and gtx950m graphics card. More than 6000 yuan are mostly game books, high-end business books or ultra-portable notebooks. You can choose between thinness, performance and heat dissipation. common software
In the process of learning, there will be some courses that need special computer software, and it is best to buy a notebook computer with a configuration that can meet the minimum operating requirements of these software. The software needed for learning in the three major directions in the hospital includes various compilers, three-dimensional CAD systems, mathematical software, single chip microcomputer related software and so on. Advanced computer language compilers such as Dev-c++, VS, VC6.0, VC++, etc. Three-dimensional CAD can use CAXA, SolidWorks, etc. Mathematical software such as MATLABKeil series, Proteus series and other single chip microcomputer related software. It also includes analog circuit software, such as MultisimVerilog compiler software, such as ModelSim.
The software that may be used in college life is not limited to those mentioned above. No matter which direction, as long as you are interested and energetic, you can develop. Of course, you don't need to panic because you don't know them well. Teachers will guide the software that needs to be used skillfully, and there are many ways to provide you with college learning opportunities. These softwares are not only necessary for courses, but also very practical tools. During the summer vacation, we might as well have a preliminary understanding of them first.
Brief comment on notebook manufacturers This section is not aimed at any notebook manufacturers, but simply introduces the advantages and disadvantages of these brands from the perspective of students. Lenovo: The after-sales service of established manufacturers is guaranteed. There are many notebook styles corresponding to different functions, and there are also many official authorized stores, but the types of notebooks are too mixed. Dell: The high-end alien game series has complete atmospheric functions and may lose its cost performance. The mainstream products are moderately cost-effective, and the workmanship is not brilliant, but it is better than thoughtful after-sales service.
Asus: The series of high-end players' country has attracted a number of belief powders, which are excellent in all aspects but low in cost performance. The cost performance of mainstream products is slightly lower than that of Dell, but the quality control is better.
Hewlett-Packard, Acer and other established manufacturers: all aspects are moderate. Future new manufacturers such as human beings, Raytheon and mechanical revolution: high cost performance and cool appearance, but poor quality control, few physical retail stores and after-sales service centers.
MSI: Good quality control, proper details handling and good experience, but low cost performance, poor heat dissipation and few physical retail stores and after-sales service centers.
