What do people who know computers mainly look at when choosing computers?

If you buy a computer, it depends on whether you buy a whole machine or DIY to buy accessories for assembly.

If you buy a whole machine, it depends on the purpose of your computer. Computer machines are generally divided into business machines and home machines. The performance of business machine is relatively stable, but the configuration will be worse, and the configuration of home machine will be better. Now home machines are also divided into games, drawing videos and office use. These refer to desktops and notebooks. Notebooks include game books and light books, so first you have to confirm which type to buy. Secondly, it is to choose brands, generally choose big brands, because the quality of big brands is guaranteed, such as HP and Lenovo. After determining the brand and use, the next step is to look at the specific configuration of the computer, and strive to achieve the greatest cost performance.

If you want to buy a compatible desktop, which is what we generally call DIY, you can buy spare parts and assemble them yourself, or you can assemble them in a store that sells spare parts. Again, first determine the purpose of the computer. For people who play games, the graphics card and CPU are stronger and the memory is larger. Drawing and video production do not require high graphics cards, but to ensure large memory, it is best to have 16GB memory, and the CPU performance is also good. You have to decide whether to buy Intel CPU or AMD CPU, followed by motherboard, memory, graphics card, hard disk, power supply, chassis, keyboard and mouse. Remember that these spare parts must use the brand of big manufacturers, which will help you stabilize your computer in the future and reduce the failure rate of your computer. It's better to use accessories from big brands. This is my experience.

Therefore, to buy a computer, first determine the purpose, then choose the brand, and finally look at the configuration.

If you really want to say, what should people who know computers pay attention to when buying computers?

I can only say that those who like to toss about computer accessories almost all buy second-hand accessories, paying attention to a cost performance and compatibility. The collocation between hardware is very important. The current CPU is completely super-performance. For desktop processors, if you look closely, the speed and performance improvement of processor update have basically reached the bottleneck. At present, the fastest development can only be said to be graphics cards, memory chips and solid-state devices.

What is the reasonable collocation of hardware in the actual use process?

Take the game as an example.

Graphics card is higher than CPU, higher than memory and higher than SSD.

There is also in the process of game machine configuration.

The default frequency of CPU is also an important reference. The default frequency of some multi-core and multi-threaded processors is low, although there are many cores and threads.

Take L5640 as an example. Although it is a 6 and 12 thread processor, the default frequency is only 2.2, and the highest turbo frequency is only 2.6.

In addition, the production process is 32 nm, and the response speed is higher than x5650. Because the production process is the same, it is all 32 nm. Because the default frequency is higher, 5650 wants to use it faster. Take the current large-scale 3D games as an example.

X5675

Even with the third generation memory chip of e CC, the frequency is 1333.

Capacity of 24gb to 32gb, using GTX960

970, or AMD7970, the game experience effect will not be much lower than the 5000 yuan of mainstream computers now. The one mentioned here, as well as the choice of motherboard, it is best to choose a processor that can support overclocking, such as alien x58 and player country x58, and raise the default frequency of CPU to 3.5. The waste heat of the processor 5 or 6 years ago can still be used.

Speaking of which, some people say that x58 architecture is too old to find the motherboard. On this issue, there is a certain difference between knowing computers and not knowing computers.

I believe that almost everyone who knows hardware is tossing. It's okay. You can go to tualatin in Baidu.

I suggest you buy a Dell brand computer. Our company has used Dell computers for 20 years, covering many types of notebooks and desktops.

Generally speaking, Dell computers have good quality, low failure rate and guaranteed after-sales service.

There is a 20 1 1 year-old DELL790 desktop in my cab, almost1year-old. 24-hour boot, still working normally.

A few years ago, I recommended a classmate to buy a Dell computer. He used it to play games and turned it on 24 hours a day. After five years of use, this machine has been running stably without any problems. Later, he gave his old machine to his relatives, and the computer was still running normally.

He later bought a new Dell computer, which is still in use.

To buy a computer, you can buy it in a physical store, in an east, or through Dell official website.

If there is personalized demand, after selecting the machine appearance through Dell official website, you should also flexibly select and adjust accessories, such as replacing high-end CPU, increasing memory capacity, increasing hard disk space, and replacing high-performance graphics cards. To meet your individual needs.

You can also buy an extended warranty according to your personal situation, so that you can use your computer without worry!

You can trust me privately when you encounter computer problems, and I will try my best to help you solve the problem as soon as possible.

I wish you a happy purchase!

Generally, buying a computer depends on the following indicators. Different people can sort it according to their own needs.

1, CPU: As the central processing unit, its main function is to interpret computer instructions and process data in computer software, and it is the core of a computer. Therefore, its performance index directly determines the performance index of the purchased computer. At present, the mainstream of the market is Pentium, Core i5 and i7.

2. Display screen: The size of the display screen is roughly 13.3 inches, 14. 1 inch, 15 inches. If you need to choose a portable and light notebook, then a 13.3 inch computer is very suitable. If you want to play games, a bigger screen is more practical.

3. Memory: Memory is an important part of a computer and a bridge to communicate with CPU. All programs in a computer need memory, so it has a great influence on the computer. If it's just for ordinary office use, a smaller computer doesn't matter. If you want to run a big game, the memory must be large enough.

4. Whether to pre-install the operating system: A computer without pre-installed operating system is a "bare machine", which will have a certain impact on the stability of the system.

5. Brand: This mainly depends on its after-sales service, computer maintenance costs and so on. Generally, computer manufacturers with good brand image are still very responsible for their computers.

The choice of this kind of computer is really a headache, especially for friends who are unfamiliar with computer hardware. Faced with all kinds of hardware, they are at a loss. So what do people who know computers mainly look at? Next, I will talk to you about this problem.

First of all, for friends who know computers, they don't actually choose a configuration directly at the first time. Instead, they first find out what the main purpose of installing this computer is, and then how much budget they have, and then reasonably choose some configurations that are similar to their own budgets according to their own purposes. For friends who don't know computers, most of them are judged according to the price. They think that the more expensive the computer, the better. This seems to be no problem in theory, but there is a big difference between those who know computers and those who don't know computers at the same price.

The first is to look at the CPU, which is also the central processing unit of the computer. Its performance determines the overall running speed of a computer, that is to say, the better the CPU, the faster the computing speed of the computer. So for people who know computers, they will focus on choosing CPU, and they know what kind of CPU they should choose to satisfy themselves. But how to choose this CPU? It is estimated that people who don't understand computers are simply confused about various models. Actually, this is very simple. If you are new to hardware, you can judge from the series and model of CPU. Let me briefly talk about it.

For Intel processors, Pentium series processors can be selected for office level, and Core series processors are recommended for home use. This Core series is divided into i3 i5 i7 i9, in which i3 is the entry level for home use, i5 is the mainstream level, i7 is the high end, and i9 is the flagship. Look at its numbers. The greater the number of the same series, the stronger the performance, and the greater the number of the same series, the better. Generally speaking, ordinary households can choose i3 series. You can choose i5 for mainstream games, i7 for multi-tasking and frequent large-scale games, and i9 for enthusiasts. For AMD, the view is actually similar to that of Intel. At present, AMD uses Ruilong series, which is also divided into R3 R5 R7 R9, in which R3 is Intel i3, R5 is i5 R7 is i7 R9, and numerically, the greater the performance, the better. Then let's look at the number of cores, threads, main frequency and cache, so that we can basically understand the positioning of CPU.

The second is to look at the motherboard. For people who know computers, the motherboard should first look at its own purpose, whether it needs more external expansion, and whether it likes large boards or small boards. It is estimated that many small partners have not figured out this size board. The so-called big board means more materials, more expansion, bigger board, better heat dissipation, but more expensive. Relatively speaking, it takes up some space, which is a fly in the ointment for those who pursue a small chassis. The small board can meet the requirements that are not very high, and it doesn't need too much expansion. Small partners who like mini-chassis. In addition to the specifications of the motherboard, we also need to look at the material of the motherboard, mainly to see whether the memory and graphics card slots are enough, and then the power supply. For the capacitor part, Japanese capacitor motherboard is preferred. For the motherboard, I still suggest you buy a better brand motherboard. The performance of the motherboard will affect the performance of other hardware. Similarly, for the motherboard, we can also use letters and numbers to distinguish its performance.

Motherboards are also divided into Intel chipsets and AMD chipsets. For Intel chipsets, the letter H is usually entry-level, such as H110H310H410, etc. B is the mainstream level, such as B360 B460 B560, and Z is the high-end board, such as Z390 Z490 Z590. In addition, the motherboard starting with z supports super. However, you need an Intel processor ending in K to turn on overclocking. AMD motherboard, A starts from the entry level, such as A320 B, the mainstream level, such as B350 B450 B550, and X starts from the high-end motherboard, such as X370 X470 X570. Relatively speaking, AMD motherboards basically support overclocking, but X series overclocking is better, and it also supports automatic overclocking. It should be noted here that AMD motherboards and Intel motherboards cannot be used together because of their different CPU interfaces. Don't buy it wrong.

After the motherboard passes, it is the graphics card. In fact, this graphics card is mainly to watch the group. If you don't have high requirements for the graphics card or are dispensable, then the graphics card really doesn't matter, and the verification can be satisfied. However, if you use it in games or some programs that need the computing power of the graphics card, then the graphics card is very important, such as various large-scale games at present, and virtual currency that relies on the computing power of the graphics card, such as Bitcoin. Because these virtual coins can be directly converted into real-life money, and they all rely on video cards, why are video cards so expensive this year? Because most of the graphics cards have been bought by these mine owners, relatively speaking, graphics cards are the third most important accessories after CPU and motherboard.

As for the hard disk, I won't introduce it much, because unlike the CPU and motherboard, the hard disk can be replaced at any time. Compared with other accessories, it is not so important. I'm not saying it's not important here, but it's weaker than other hardware. We can buy the corresponding hard disk according to the type supported by the motherboard. At present, it is basically based on solid-state disks, and high-end motherboards reserve m.2 interface solid-state disks. So it is right to buy according to the type supported by the motherboard. In fact, every accessory is very important to the computer itself, because it is indispensable, but it is only a relative priority. If computer hardware is really divided into primary and secondary, then CPU ranks first, motherboard ranks second, graphics card ranks third, power supply ranks fourth, memory ranks fifth, hard disk ranks sixth, and chassis ranks seventh. I wonder what my friends have to say about this arrangement.

What do people who know computers mainly look at when choosing computers?

Choosing a computer must mainly look at CPU and graphics card. Whether these two characters can be bad or not is very troublesome, so we must buy them well. In the latter two stages, you usually need to replace it, which costs a lot of money, which is equivalent to buying a new computer. There is no need to tinker. If it is a notebook, theoretically you can't replace the CPU and graphics card at all.

As for the memory hard disk, whether it is a desktop or a notebook, upgrading is very simple, unless there are some special types of notebooks. Generally, you don't need to replace the original memory or hard disk, just add it directly.

Another thing to note is that if you buy a desktop, you need to pay attention to buying a good power supply. The power supply is for the mainframe. If the power supply is unstable, the service life of the host hardware will be greatly reduced. This is generally not felt, but it will cause damage to your computer invisibly, so it is very troublesome. In addition, if the power supply is not enough, the computer will suddenly crash, so the power supply is also a component that needs attention.

As for the others, you can choose according to your own budget and preferences. As long as you don't choose small brands, there is generally no problem.

I usually buy computers mainly by CPU, memory, graphics card and motherboard.

1、CPU

CPU ranks first, and a good CPU is like a locomotive. No matter how good the train is, it's no use without a good locomotive. With the fuselage of Harmony and the era of steam locomotives, you can imagine what it would be like.

There are two camps of CPU, Intel and AMD. Personally suggest Intel, which is also subjective. I always feel that AMD's CPU is not as fast as Intel's and its stability is poor.

Step 2 remember

When I was studying computer before, I saw a vivid metaphor: memory is like a transit station between CPU and hard disk. The bigger the transfer station, the faster the overall operation speed, and vice versa. The reason for this transfer station is that the speed gap between CPU and hard disk is too big. If the output instructions of CPU are directly executed by hard disk, it will be very slow and slow down the speed of the whole computer.

The operating mechanism is: the software in the hard disk is transferred into memory, calculated in CPU and then put into memory. If you want to save it, it will be stored on the hard disk. Before turning off the power, the software was running in the memory. After turning off the power, there is nothing in the memory.

There are many brands of memory, Kingston, Weigang and Pirate Ship. If you buy capacity now, it is recommended to buy a single piece of 8G, which is convenient for future upgrade.

3. Graphics card

Whether playing games or office design, graphics cards are becoming more and more important in the whole computer. For more than 90 years, a voodoo graphics card was released. Some games can only be played with voodoo graphics cards, forcing many players to upgrade. Now, it is basically impossible to have a smoother game, better special effects and more beautiful pictures without a powerful graphics card. So the choice of graphics card is also very important. This choice is as good as possible within the acceptable range, and hardware upgrade is always greater than software optimization.

4. Motherboard

A computer is unstable, and the motherboard is very important. After all, CPU, memory and graphics card are all plugged in. The motherboard is unstable, the capacitor Explosicum, the circuit falls off, and the interface solder joints are welded, which is really fatal, so choosing a good motherboard is also a necessary requirement for a good computer.

Choose first-line brands, such as ASUS and Gigabyte. Adopt new technologies as much as possible. As the saying goes, buy new ones instead of old ones. Of course, classic models that have been tested for many years are also among the choices.

Having said that, there is actually another important place in the configuration of computers: balance. Don't use small horse-drawn carts, and don't use big horse-drawn carts. Balance is a necessary condition for playing computer.

I hope you can buy your favorite computer.

In reality, most people buy computers by looking at the price first, and then at the cpu and graphics card. In fact, people who know computers will not only look at these points, because these are the points that determine the comprehensive performance of a computer:

Cpu mainly depends on the number of cores, main frequency, and the higher the parameters, the better the performance. It is the brain that determines the speed of a computer. Both office and games need a good CPU, otherwise it will be weak in the future!

Graphics card is the key to playing games. Look at the frequency, bit width, sp and core of the memory, and finally look at the memory. General gamers or people who edit videos should pay more attention to graphics cards, and graphics processing performance is very important!

Hard disks are divided into mechanical hard disks and solid-state hard disks. Mechanical hard disk depends on the number of revolutions, the higher the number of revolutions, the better, and then on the capacity, the capacity is much larger. Solid-state hard disk is better and more expensive than mechanical hard disk, and the startup speed is faster, that is, smaller, but now we recommend dual disk, which does not affect the speed or the storage of files.

Generally speaking, the larger the memory, the better the relative performance. 4-8G memory is enough if you are just working or playing games. However, if it is a PR professional, it must be at least 16G, otherwise it will be stuck frequently.

Motherboard is actually the foundation, any good CPU or graphics card, if there is no good motherboard, then it will only be difficult to move!

So people who know how to choose a computer will look at these points and measure the price of the whole computer according to the model and market price of each spare part.

People who know computers mainly consider three points when choosing computers. First, computer configuration. Second, the computer price. Third, the design work, of course, includes the face value, and the face value is also an important part of choosing a computer. Let me talk about the above three parts:

First, computer configuration.

Hardware configuration determines the performance of a computer, and the performance of the computer determines the service life of the computer. After all, no one wants a computer whose performance is not enough after two years of use, so the computer configuration is the first thing we should look at when choosing a computer.

So how do you look at the computer configuration? First of all, whether it is a notebook or a desktop, the choice of hardware configuration is to buy new ones instead of old ones. For example, Intel's 10th generation Core has been released, and the 10th generation i3 can play the 9th generation i5, and the price i3 is cheaper, so you must buy the 10th generation i3, although nominally i3 is second to i5.

In addition, the graphics card, motherboard and CPU follow the principle of buying new products instead of buying old ones. There is also a principle: the bigger the number, the higher the positioning and the better the performance of the same generation of products. For example, RTX 20 series graphics cards also belong to RTX 2080. Even if it is a beggar version, its performance is RTX 2070.

In addition to the above-mentioned bulky products, DDR4, that is, the fourth generation memory, is generally purchased as memory, depending on parameters such as frequency and memory timing. For solid state, it depends on whether the protocol supports SATA or NVMe, whether the interface is m.2 or SATA3, as well as reading and writing speed, flash memory granules, warranty and so on.

Second, the computer price.

Hardware products of the same model will have different prices according to different brand positioning. For example, both graphics cards are RTX 2080, but the prices of MSI magic dragon and ASUS Raptor are different, but their positioning is similar, and they are both top models in graphics cards.

Therefore, regardless of personal belief, I still suggest buying a more advantageous price for the same positioning between products of the same model. For another example, when the budget is insufficient, the performance of the product is given priority, and then the premium brought by product positioning and belief dividend to consumers is considered. In other words, if the budget is limited, it is right to buy products with higher cost performance.

Third, design work.

As mentioned above, the same model of hardware products will have different brand positioning and different prices, but what if the prices are the same? Here we have to consider a problem, that is, design work.

A simple example, ASUS B360 TUF and MSI B360 Mortar, both motherboards of B360 chipset, are the two most popular B360 motherboards with the same positioning and similar prices. What should we watch at this time?

This time depends on the design and workmanship of the two products. For example, MSI motherboard power supply has 3 mos per phase, and ASUS has only 2. For example, MSI motherboard has dual m.2 slots but no m.2 network card, and ASUS does. When faced with such a choice, just choose the part that you value more according to your own needs.

abstract

Finally, I want to say that the value of a computer or computer hardware varies from person to person, but most beautiful things are not cheap. Think about which parts you value more, and choose according to your preferences!
