I also analyze the quality of the computer configuration and how to understand the quality of the co

The performance of a computer is mainly determined by the following accessories:

1) CPU: Determine the running speed, such as Inteln Pentium Dual-Core, where "" refers to its computing speed, but the unit "G" here is different from the "G" of the hard disk, not the size, the "G" of the CPU is the frequency, that is, it can be calculated several times per second.

2).Motherboard: Determines the speed and stability of computing, and can be divided into many types due to the different chips used in motherboards.

3) Hard disk: determine the speed and size of read and store data, such as Seagate 500GB 16M (serial port scattered) ST3, of which 500G is the size, 7200 is the speed, the speed determines the speed of reading and storing data, and 16M is the cache of the hard disk, which also determines the speed.

4) Graphics card: Determine the quality of the screen display effect and display speed, its performance index generally depends on its video memory and number of bits, such as people often say double 256, that is, the memory and bandwidth bits of the graphics card are 256 bits.

5) Memory: Memory is very important for the operating system, as more and more software consumes more and more resources, we currently need to let the computer be configured with 2G memory or more. XP system, 1G of memory is also enough, but the new Win7 operating system needs at least 2G of memory.

Personally, I think that buying a computer or depends on personal use, if you don't need a particularly high configuration, there is no need to buy a high configuration, because the high configuration also thinks it costs more! Inferior: If you need to play big games, you need a good discrete graphics card.

In addition, the easiest way is to use software to detect, some software will conduct systematic analysis of the computer, such as "Master Lu", "Optimization Master", "360", etc., you can install it in the U disk after **, carry it with you, and analyze and score the computer configuration at any time.

Generally,It depends on what you do.,It's OK to play general games and office.,But if it's a drawing 3D.,Or play a large 3D can't be OK.,And I don't know what you say about the quality of the configuration.。

If you want to play new and new single-player games, and large online games, it is recommended to change the graphics card.

Your graphics card interface is PCIe-16, so if you like to play DX10 new games, it is recommended to change to a Shadow 8600GT 799 yuan.

It's basically OK to just change the graphics card.,Playing games generally has high graphics card requirements.,You have enough memory.。

Test the performance of your computer with Master Lu to know the high and low configurations.

Open the start bar, hover over Computer or My Computer, and right-click Properties to view configurations.

Depending on what you're using it for, depending on what you're using it for.

Take a look at the number of cores in the CPU.

At present, the mainstream is dual-core, single-core (such as Pentium 4) has long been discontinued, and the high-end has quad-core.

Second, look at the production process.

The current 45nm CPU is popular, the previous generation was 65nm, and the older 90nm (rare). The manufacturing process of 45 nanometers refers to the width of the wire connection between the transistor and the transistor (referred to as the line width), which simply means that it can be on the chip in the same area"Squeeze"More transistors, more transistors leads to higher performance. Even if the number of transistors does not increase, the area of the chip can be reduced accordingly, so that the power consumption and temperature can be reduced by a lot.

Third, look at the size of the L2 cache.

The CPU is in the computer"Run"Sometimes, because it runs too fast, other hardware such as memory can't keep up with it, so CPU manufacturers have introduced caches. Judging the quality of the CPU by looking at the size of the second-level cache is mainly for Intel's CPU, because Intel's CPU relies heavily on the second-level cache, Intel's CPU second-level cache is mainly used to store data, and the first-level cache stores the address of the second-level cache, and these data are numbered such as a-z in the first-level cache, and the CPU needs to retrieve the data directly from the first-level cache when the number of the data is retrieved, for example, For example, the L2 cache is the content of a book, and the L1 cache is the directory of the book, which is why Intel's CPU L2 cache is particularly large, while the L1 cache is particularly small. AMD's CPU design is different from Intel's, AMD's CPU Level 1 cache is used to store the most commonly used data, and the Level 2 cache is used to store more commonly used data, so AMD's CPU Level 1 cache and Level 2 cache are about the same size.

Theoretically, Intel's CPU is more efficient, and the CPU can directly retrieve the number when it needs to retrieve some data.

Fourth, look at the main frequency. In the case that the first three are the same, the quality of the CPU can be judged by the level of the main frequency, most of the CPU main frequency is around the to, and now the highest is not exceeded, because if the main frequency is too high, the heat and power consumption will also increase accordingly.

It depends on what you do, some people are game enthusiasts, and the graphics card must be high, and some people use design software like UG, which requires the memory and CPU to be as high as possible, so different requirements and performance standards are different.

If from the perspective of the general public, the third or fourth generation i5 + minimum 4G memory + GTX660 graphics card can be regarded as better, this standard is also a watershed, higher than this configuration (such as i7), it can be said that it is more feverish.

The configuration lower than this belongs to the low-end one; The main representative models are: third-generation or fourth-generation i3 + minimum 4G memory + GTX650 graphics card.

Or FX6300 + minimum 4G memory + GTX650 graphics card and low-end are office configurations, such as G2030.

It's very simple, go to the next Master Lu, this is the easiest, he will give you a rating, the more points the better.

You go to the Internet to see,Jingdong's machine and then search**The most appearing**,The most important thing to buy a computer is not to be slaughtered。

This one is the same as people. A high income naturally allows you to consume more things. The same goes for computer performance. Strong performance can be opened more. Poor performance, cards, and so on become normal. Overworked.

The power of the chess software is controlled by a computer program and has nothing to do with the computer hardware.

How to judge whether the configuration of the computer is good or bad:

1. Processor, CPU processor, the core part of the brain of the computer, the collocation of the processor can be seen the overall grade of a computer, the CPU has a dual-core four-core and an eight-core, we all know that the eight-core is much faster than the four-core The higher the processor, the faster it can be used.

2. Graphics card, graphics card is a place that gamers pay more attention to, generally choose independent graphics cards, and now the market is basically independent graphics cards or dual graphics cards, so there is no need to worry about the problem of integrated graphics cards, Nvidia's mainstream graphics cards GTX series and AMD's HD are not bad, and the general large-scale games can also run. The video memory is generally 512M and 1G, and the bigger the better.

3. Memory, needless to say, is now mainly 2G and 4G memory, which is enough to cope with many programs running, if you use office software, you can choose to add a memory module to increase memory.

4. Hard disk, computer hard disk mainly looks at the capacity, the current standard hard disk capacity is 500g, or more than 500g, the important point of the hard disk is the speed of the hard disk, the higher the speed of the hard disk, the faster the reading speed of the hard disk, most of the common hard disks are 5400 mainstream 7200 rpm, but ** is generally not cheap.

CPU processor, the core part of the brain of the computer, the collocation of the processor can be seen the overall grade of a computer, the CPU has a dual-core, four-core and eight-core, we all know that the eight-core is much faster than the four-core The higher the processor, the faster it will be used.

Look at the motherboard, the motherboard is also the core component of the computer, generally use ASUS's on it, don't choose some miscellaneous brands that you haven't heard, you don't know how to die in the later stage, ASUS's motherboard is generally stable and overclocking, and the materials are better.

There's also memory.,Memory mainly depends on the size of the capacity and the brand.,Memory capacity can be satisfied with 4G.,Of course, more than 4G is better.,It's much better than 2G when playing.,The memory is large and runs fast.。

Graphics card,First look at the parameters of the graphics cardThe chip of the graphics card determines the typing of the graphics card, mainly to look at the graphics card's video memory and bit width and core frequency, video memory frequency, and one thing to pay attention to is heat dissipation, at present, the memory displayed by the graphics card is more than 500m, and the bit width is 128. The value of the graphics card is that the larger the performance, the better, so you can buy a larger value when buying, and more than 500 is enough.

There is also a hard disk, the main thing to look at is the capacity, the current standard hard disk capacity is 500g, or more than 500g, the important point of the hard disk is the speed of the hard disk, the higher the speed, the faster the hard disk read speed, most of the common hard disks are 5400 mainstream 7200 rpm, but ** is generally not cheap.

Computer display screen, the monitor mainly depends on personal preference size and looks comfortable, it is generally recommended to buy a brand, the monitor is generally not very expensive, do not buy miscellaneous brands for a long time will have problems, such as my miscellaneous brand of display used for less than half a year, the screen appeared a few green lines across the screen, the result is that the more lines are used, the black screen some time ago, and then I bought a brand It feels good.

Look at the method of computer configuration, open the computer and find "My Computer" on the desktop, and the right mouse button on the stand-alone machine is now the property at the bottom of the options. Click on the properties in the options to enter the device manager, and then we can see the basic information of this computer, as well as the configuration or something.

If you don't understand the computer at all, then you can look at how well your computer is configured this way. The bigger the number is smaller than the number, the better, (of course, I'm not saying that the run is still degree) 2G memory is better than 1G, the third generation of memory is better than the second generation, (the third generation of memory is 1333hz, much higher than the second generation and the first generation, and the technical rules are different, think about who is easier to gamble on the eight lanes and four lanes) The higher the graphics card memory, the better (the higher the video memory, the faster the processing pattern), the larger the hard disk (the larger the room, the more furniture can be placed), the faster the speed, the better, the faster the speed, the faster the data is read, The higher the number of CPU cores and frequency, the better (the faster the number of data and floating-point operations are processed, think of one core as a person's brain, and six cores as six people's brains. The power supply of the host is a good quota, and it depends on the weight, the better, of course, the higher!

The chassis is to look at the weight, the heavier the better, (the heavier proves that the material is sufficient, not easy to break or deform), but also to see whether the switch button of the chassis is easy to break, (the case with enough material but the button is easy to break is not easy to sell when bought at a cost.) *** with blue light *** is the best, of course** is also very expensive. Needless to say, if the graphics card is high-end (high-end, you think of it as a graphics card fan with two or three, the kind that is lined up, and then accounts for two or three PCI interfaces, and then looks at pure copper or degree copper, etc.), motherboard?

Now the popularity of solid-state motherboards, some also naturally come with solid-state drives, the darker the color of the motherboard, the better, the best black, and then you have to see how many layers of the motherboard are made of yellow, the thicker the better.
