How to choose a notebook What parameters should be paid attention to

In fact, buying a laptop now is like buying cabbage, and there is basically no need to make any comparisons, unless you are buying a high-end machine.

The reason is actually quite simple, the main factor in buying a laptop is your own budget and personal needs. Once the budget is determined, the configuration of the notebook computer is determined, (as long as you compare a few more and not be fooled by the merchant).

Secondly, as long as you understand the performance of the machine you buy, whether it can run the software you need, as far as I know, the current laptop can run these two software, of course, there will be fast and slow, this is related to the configuration, but it does not affect your application.

Because it is all flat design, it is recommended to use the CPU of i5 will be better. Now the general 4G memory is also enough. There's really nothing else you need**!

Why not talk about graphics cards, because in your budget, graphics cards perform the same, there are not many options, they are almost the same).

CPU you need i5 or above.

Graphics card N card gt335m or more The bigger the number, the better ATI HD5650 or more The bigger the number is also the better Around 5000 you can buy GT335M, 425M, 435M, etc. 310M Don't want Video memory to be 1G or more HD 5650 5730 etc.

Hard disk doesn't matter, but many of them are 320g 7200 rpm or 500g 5400 rpm, the higher the rpm, the stronger the hard drive's read and write capabilities.

RAM is mostly 2G which is sufficient.

Cons: The keyboard area is a bit small.

1. CPU type. At present, CPUs on the market are mainly produced by two manufacturers, namely Intel and AMD, among which Intel's Core series, which is the most widely used; AMD is owned by the Ryzen Ryzen series. Generally speaking, the performance of i9>i7> i5>i3, but it is not absolute, and it also depends on their algebra and suffix, for example, i7-11 generation is not necessarily worse than i9-7 generation, and most of the suffixes of general notebook CPUs are HQ standard voltage version and U low voltage version.

2. Main frequency. The main frequency refers to the clock frequency of the CPU, which is simply the working frequency of the CPU during operation. Generally speaking, the CPU we say is xx GHz, and this XX GHz is the main frequency of the CPU.

The higher the frequency, the faster the CPU. So in the same generation of products, the higher the main frequency, the better. In addition, the number of cores refers to the number of chipsets on the CPU that can process data.

For example, a single core is a chip that only has one chip to process data. The more cores there are, the more powerful the data processing capabilities are, and the more cores the more cores the better the performance will be at the same frequency. Of course, the heat dissipation capacity of the machine should also be considered when purchasing, the higher the main frequency, the greater the relative heat generation, the more energy consumption, in non-charging mode, the standby time is relatively short, so there are pros and cons to each, don't blindly compare, weigh all aspects before buying.

3. Graphics card model. Graphics cards are a major concern for users, especially for gamers. The current mainstream graphics card manufacturers are mainly AMD and NVIDIA, and the graphics cards of the two platforms are not very different, so there is no need to be too entangled.

However, you need to pay attention to the number behind the graphics card, generally speaking, the higher the number, the better the performance, for example, RTX3090> RTX3080> RTX3080. Regarding video memory, the larger the video memory for the same graphics card model, the greater the performance advantage. In addition, the performance of the independent display is stronger than that of the integrated display, but the power consumption of the independent display is higher than that of the integrated display, and the heat generation is relatively large, so when you buy, you should buy according to your own needs.

4. Hard disk. At present, there are two kinds of hard disks on the market: solid state drives and mechanical hard disks, and solid state drives have better shock and drop resistance than mechanical hard disks, and can minimize the possibility of data loss in the event of collisions and **. The performance improvement is also more than 2 times that of HDDs, in addition to being less noisy, but higher than SSDs.

5. Memory. Memory is used to temporarily store the computing data in the CPU,It can play a role in the icing on the cake,At present, the mainstream is 16GB,It is not recommended to buy 8GB or less,Of course, if you are a player who focuses on large games,If the budget is not tight, it is recommended to use32G memory,The larger the memory,The game will run more smoothly。

Laptops are one of the important electronic devices we need to use in study, office and entertainment, it is light and fashionable, relatively cheap to carry, and it is also one of the items that we often must bring when we go out, so when we buy laptops, how should we choose laptops, so I will introduce you to the 4 key points of choosing laptops.

The first point of how to choose a laptop: the hardware aspects of the laptop and the overall configuration parameters of the computer.

1. Under normal circumstances, notebooks are definitely inferior to desktop computers in terms of performance, and should not be compared with desktop computers when choosing, but everyone must choose those with better heat dissipation functions when choosing laptops, so as to prolong the life of the notebook and prevent overheating and causing crashes.

2. When we choose a notebook, the most important thing to look at the parameters is to look at the CPU of the notebook, to choose those CPUs with large frequency and cache, the CPU determines the running speed of the notebook and the hardware performance in all aspects, so choosing a good CPU is very important for the notebook.

3、When choosing a notebook, you should also pay attention to the graphics card of the notebook,Especially for those gamers,The graphics card determines the quality of your game,Most of the current notebooks have also installed independent graphics cards,But we must not be confused by the high-performance graphics cards of the merchants,When choosing a notebook TV in the empty space,Whether it is a N card or a card,The most important thing is to pick it up and experiment it yourself。

The second point of how to choose a laptop: the ** of the notebook.

Usually, if it is about 1000-2000 notebooks, it can only be used for study or work, basically can not play games, the performance is extremely low, it is recommended to change the channel directly. A notebook of about 2500-3500 yuan, with average performance, will be a little stuck when playing games, which is more suitable for student parties and office workers. If a laptop of about 5000-1w yuan is a high-end computer, it can run all kinds of games and office very smoothly.

The third point on how to choose a laptop: the appearance of the notebook.

The appearance of the notebook must also be paid attention to when we choose, in addition to the appearance of the notebook, the chain must also have a variety of different interfaces, which is convenient for us to use.

The fourth point of how to choose a laptop: notebook keyboard design.

The keyboard of the notebook is one of the most commonly used parts of the computer, so it is also very important, when we choose a notebook, we should choose those keyboards that feel easy to use and very comfortable to use, so that you will be more efficient in the game or office.

The CPU is Core 2

T6500.

The graphics card is an nvidia mid-range graphics card, business.

It's no problem to play games, and the after-sales service is very good, and there are all over the country, and the quality is no problem.

Right-click on my computer, click Properties, then click Hardware, and then click Device Manager to get the parameters.

The processor is the human brain, also known as the CPU, and its quality directly affects the speed of the computer.

Graphics card even if it supports your computer's display chip, good graphics card.

Hard disk is simpler, the larger the hard disk, the larger the storage, the hard disk has 5500 rpm and 7200 rpm, the latter reads data faster.

Memory is mainly the bridge of CPU communication, and the running of all programs of the computer is carried out in memory, so the memory has a great impact on the computer, as for the running speed, it mainly depends on the size of the CPU and memory.

Computer cache Because the internal data transmission speed of the hard disk is different from the external interface transmission speed, the cache plays a buffering role in it. The size and speed of the cache are important factors directly related to the transfer speed of the hard disk, which can greatly improve the overall performance of the hard disk. When the hard disk accesses the fragmented data, it needs to continuously exchange data between the hard disk and the memory, if there is a large cache, the fragmented data can be temporarily stored in the cache, reducing the load on the external system, and also improving the data transmission speed.

As for the expansiveness you said, I don't know, I don't know who you're listening to.
