What are the main considerations to measure the quality of a computer

Personally, I think an Internet café-style computer is a good choice. If you don't like it, you can choose the speed reference Athlon 3000+ or more RAM 512MB or more Graphics card 128MB I don't feel like I can play any game in the Internet café and feel that its performance is not bad in terms of gaming! Generally smooth!

Illustrate that the general computer can complete the needs of home, business, and gaming! When configuring a computer, the memory must first be sufficient! Nowadays, the average computer combined with the current software generally widely uses 1G memory.

It is fully for general business, i.e. game needs! However, the 128MB used in the past to run the current software is obviously difficult! When running files, a lot of memory is pumped out, resulting in insufficient memory, and the speed is very slow, and now the memory is generally enough!

If the software is bigger in the future, the memory required will be larger, and it should be replenished in time! It should now be recommended in 1g! However, when the memory is added (referring to the future), the speed of replacing the CPU and motherboard in time is not possible!

It's still a problem to be able to use the memory to the fullest! Graphics card nowadays, the average hardware enthusiast doesn't care about its capacity, and some have a video memory of 512MB or even less than 128MB. Obviously there is not everything, its frequency and transmission speed are the fundamentals of performance.

The main thing to pay attention to should be the bit width, for example: 128MB graphics card, the bit width is 128D compared with 512MB 64B, the performance is still 128B advantage! Because of the wide bits, the bandwidth can be calculated!

Large bandwidth is the foundation of performance, which can give full play to the video memory, otherwise no matter how large the capacity of the video memory is, it can only be stuck like pouring water in a bottle (video memory capacity)! Therefore, it is recommended to buy a bottle with a large mouth (bit width) and use 128 bit width, which can meet the performance of current business, games and so on. Then there is DDR1, DDR2, DDR3, which is also the speed at which the table is obviously stored!

This means that speed can be exerted in a wide channel! Then there is the speed of the graphics card interface on the motherboard, AGP : 1x 266MB s 2x 532MB s 4x 1G s 8x X4 can be completely suitable for 3D.

For gaming performance, it's okay! Its data transfer rate can reach 1G! It is recommended that you need to look for a performance ratio, preferably with PCI-E 16X can reach 8G!

This is online shopping, and there are a lot of hardware devices in it. **Definitely re-excellent. Because the above sellers like to mark ** very low, otherwise I am out of 10 people out of 8, I can see it at a glance, so ** is very reasonable, I recommend you to buy on it.

If you don't want to bother, you can also choose to buy it appropriately in your own local area. There are also a lot of second-hand ones. Good luck finding a device that performs well!

It's detailed enough, I wish you to choose a machine with good performance, I'm tired and so serious that you don't choose me? I'm playing inside QQ Q! Choose me! Beg.

It should be said that all hardware should be considered, such as the display performance of your monitor, the gaming performance and functions of the graphics card, the performance of the CPU, the matching of memory, as well as the capacity and transfer speed of the hard disk and the size of the cache ......and so onThe computer should be gradually refined from the whole to the part, and a reasonable configuration should be obtained according to your own needs.

The performance of a computer is mainly determined by:

1. Processor CPU

The processor is the core of computer control, a set of reasonable computers, look at the processor to see the grade of the whole machine. So what parameters does the processor mainly look at? There are mainly cores, main frequency, etc., the core is dual-core, quad-core, etc., the main frequency mainly depends on the frequency value, in general, the higher the main frequency and core, the better, such as Intel's i7, AMD's FX8300.

2. Motherboard. The motherboard is the core component of the computer, equivalent to a platform, different hardware works on this platform, the motherboard mainly looks at the work and chipset, the workmanship is mainly the use of sufficient materials, whether it is the all-state capacitor design, etc., how the overclocking performance is a more important parameter, the motherboard has little impact on the speed of the computer, so we pay attention to the stability and overclocking ability of the computer motherboard. So so; The stability of the motherboard with the all-old capacitor design is very good, and the workmanship and materials of the brand motherboard are better.

3. Memory. Memory mainly depends on the size of the capacity.

4. Graphics card. The parameters of the graphics card are the most important thing for us to look at the graphics card chip, and the chipset determines the grade of the graphics card. The other main things to look at are: the graphics card's memory and bit width, core frequency and memory frequency, etc., and one thing to pay attention to is heat dissipation.

At present, the general graphics card video memory is 512M, and the bit width is 128bit, and the larger these values, the better the graphics card performance.

There are also hard drives, power supplies, etc.

The CPU is the chip of a computer. The quality of the computer cannot be determined by a single accessory, and the overall coordination depends on the overall configuration. If the motherboard is poor, no matter how good the graphics card and CPU are, the performance will not be able to play, and it will be in vain.

For example, the current trend is CPU i3 RAM, 4G DDR3 1333 graphics card, D5 450 or the cheaper 550. Motherboard H61 or H67. In the future, the CPU will also come out with a bulldozer series.

Right now, only high-end motherboards support bulldozers. The light motherboard is about 1,000. If you have money, you can engage in high-end points on the motherboard, and if you want to upgrade the bulldozer series CPU out, you can directly buy a CPU and replace it with the high-end motherboard, and if you want to upgrade it, it will support DDR3 1333 and 1600 memory, and then 1333 will be outdated, and you want to use 1600 memory, which is also very convenient for future upgrades.

Therefore, if you buy a computer, it is completely necessary to spend more money on the motherboard, and the accessories other than the motherboard power supply must be coordinated. It's the same when it comes to power. The quality of the computer and the power supply are important links.

CPU overclocking is popular now. Originally, the voltage is sufficient, but overclocking will require voltage. Generally, those who can overclock know to turn up the voltage as well.

So it's a test for the power supply if it's not good. The consequences can be imagined. People who are bold will overtake the graphics card (the kind that is not afraid of being super bad if they are rich, or they are very confident in their own technology).

So if you have a machine, the power supply and motherboard are the key.

The speed mainly depends on the CPU and memory! The outside quality depends on the graphics card! The CPU is the heart of the computer! CPU also needs a processor!

Computer configuration: A measure of how well a computer performs.

1. The version of the operating system installed on the computer; 2. The type of processor configured by the computer; 3. The size of the memory installed on the computer; 4. Whether the operating system is 32-bit or 64-bit.

4. Check whether the system type is 32-bit or 64-bit, in general, 64-bit has better processing power than 32-bit.

graphics card, the frequency of the graphics card reflects the speed of the graphics card to a certain extent; The capacity and capacity of the graphics card determine the ability of the video memory to temporarily store data, so the frequency and capacity are very important.

Hard disk. The hard disk mainly depends on the speed, and the higher the speed, the better. Also look at the memory, the larger the memory, the better.

In fact, the performance of the hardware should be high-profile, and compatibility should be considered, and only reasonable configuration can give full play to the best effect.

Hope it helps.

It's the combination of the individual components! If you sell a notebook, the 5000 is basically very powerful! Is it okay to have a desktop host of about 3000?

The performance mainly depends on the CPU, motherboard, memory, if you need graphics processing, it also depends on the display performance, in addition to the performance of a single element, but also depends on how the system is matched.

The two major factors that determine the performance of a computer, the configuration of the computer and the IQ of the human brain, are indispensable

The configuration should be balanced, ** should be reasonable, and it is good to be able to use sex.

Mainly look at the following aspects:

1. CPU (very important).

2. Motherboard (important).

3. Graphics card (if you want to play large games, this is also very important) 4. Memory (more than 4GB can be basically satisfied).

5. Hard disk (not important).

Usually for a computer host, mainly look at the motherboard, CPU, memory, graphics card, the motherboard is divided into a variety of types, what kind of bus structure is supported, co-processors, etc., there are more CPUs, the higher the level, the better, the current mainstream i7 is good. The memory is also divided into dd2 or dd3, 1333 or 1666. There are too many brands of graphics cards, and usually the larger the video memory, the better, and the higher the resolution, the better.

There are more displays, depending on what brand you buy, like Apple Display, 1 20,000 are available.

1. CPU 2, graphics card 3, motherboard.

These three are the most important.

Others are also important, but they are not worth much, such as memory, hard disks (except for SSDs), and of course, monitors.

Press Motherboard, CPU, Hard Disk, Power Supply, Graphics Card, Memory, Display.

CPU, graphics card, memory, hard disk, motherboard, power supply, chassis.

Graphics card: A computer with a high CPU and a graphics card will be very good.

Computer configuration: A measure of how well a computer performs.

The quality of the computer configuration can not only look at the level of a certain accessory, but to look at the whole, motherboard, CPU, memory, graphics card, hard disk, power supply, these are all factors to consider, even if one of the performance is very high, and the other accessories are average, it will cause some bottlenecks in performance, so when building a computer, we should consider the whole, not just consider one of the most basic accessories of a computer.

Motherboard,,, graphics card... Hard disk. Monitor (if desktop). Power supply.

Look at the attributes, generally the bigger the better, and there are compatibility problems, you test the machine is easy to use.

Performance metrics for your computer.

The main technical performance indicators of the computer are: main frequency, word length, memory capacity, access cycle, computing speed and other indicators.

1. Main frequency (clock frequency): refers to the number of pulses output by the computer CPU per unit time. It largely determines how fast your computer runs. Unit: mhz.

2. Word length: refers to the number of bits of binary data that can be processed by the computing parts of the computer at the same time. The word length determines the accuracy of the computer's calculations.

3. Memory capacity: refers to the total number of bytes of information that can be stored in the memory memory. It can often be used as a byte with 8 binary bits (bits).

4. Access cycle: the memory is independent for two consecutive times"Read"or"Write"The minimum time required for operation, in nanoseconds (ns, 1ns = 10-9s). The memory is completed once"Read"or"Write"The time required for the operation is called the access time (or read and write time) of the memory.

5. Computing speed: It is a comprehensive indicator, and the unit is MIPS (million instruction seconds). The factors that affect the computing speed are mainly the main frequency and access cycle, and the word length and storage capacity also have an impact.

Other indicators: machine compatibility (including data and file compatibility, program compatibility, system compatibility and equipment compatibility), system reliability (MTBF), maintainability of the system (MTTR), maximum number of external devices allowed to be configured by the machine, graphics and image processing capacity of the computer system, audio input and output quality. Chinese character processing capabilities, database management systems, network functions, etc.

The performance** ratio is a comprehensive measure of a computer's performance.

You can use some testing software, such as PCMark DMark and other software, to run a score to see how well you can get a general idea of the overall level of your computer.
