Processor is the core of computer control. If a computer is properly matched, you can see the grade of the whole machine by looking at the processor. What parameters does the processor mainly look at? There are mainly cores and main frequencies. The cores are dual-core and quad-core. The main frequency mainly depends on the frequency value. Generally speaking, the higher the main frequency and core, the better. For example, the author's computer processor is intel E4300, and the dual-core main frequency is 2. 10Ghz, which belongs to the previous generation processor products. Obviously, the main frequency is 2. 10Ghz, which is not high. At present, the main frequency of processors with more than two cores is above 2.

Two: What does the motherboard look at?

Motherboard is the core component of computer, which is equivalent to a platform. Different hardware works on this platform. Motherboard mainly focuses on work and chipset. In terms of workmanship, it is mainly whether the materials are sufficient, whether it is a fully dead capacitor design, etc. Overclocking performance is a more important parameter. Motherboard has little effect on computer speed, so we are concerned about the stability and overclocking ability of computer motherboards. Generally speaking, the motherboard designed by full dead capacitor has good stability, and the brand motherboard has better workmanship and materials.

Three: What does the memory look like?

Memory mainly depends on capacity and brand capacity. At present, the hard disks are all over 2G, which can fully meet everyone's requirements, so I won't introduce them here.

Four: What does the graphics card look at?

The most important parameter of the graphics card is the graphics card chip, and the chipset determines the grade of the graphics card. Other main ones are: memory and bit width of graphics card, core frequency and memory frequency, etc. Another thing to pay attention to is heat dissipation. At present, the general memory of graphics cards is 5 12M and the bit width is 128bit. The larger these values, the better the performance of the graphics card. The graphics card chip shown below is: GT240 belongs to the low-end independent graphics card level. Take the graphics card of a popular game as an example.

The graphics card parameters in the above picture are those in 600 yuan at present, which can meet the needs of most games at present. You can compare some good graphics card parameters.

The latest graphics chipset rating table is attached below:

Finally, here is a brief talk about the application performance of entry-level graphics cards, mid-range graphics cards and high-end graphics cards. I. Entry-level graphics cards mainly use G2 10, GT220, and HD5550 and HD5450 chipsets.

You can know the grade of the graphics card by looking at the chipset from the graphics card parameters. General entry-level graphics cards are suitable for surfing the Internet, general entertainment and general games. What is the general game novice friends may not know. Here briefly, the general games are mainly World of Warcraft, CF, QQ free fantasy and so on. Getting started with graphics cards will be more difficult for large games and will not run smoothly. It is necessary for players to choose high-end discrete graphics cards.

Five: What does the hard disk look at?

At present, the most popular hard disks are Seagate and Western Digital. As we all know, hard disk mainly depends on capacity. At present, the standard hard disk capacity is more than 500G, but it is easy to ignore the speed of the hard disk. The higher the rotational speed, the faster the hard disk reading speed. At present, most hard disks are 5400 rpm, while the mainstream is 7200 rpm. At present, the reading speed of solid-state hard disk is the fastest, but it is expensive at present and is not recommended.

Six: What does the monitor see?

In fact, there is nothing wrong with the monitor, mainly depending on whether the monitor is bad or not.

Seven: what does the chassis power supply look at?

Chassis power supply is the key point that everyone ignores, but you must correct the previous misconception that chassis power supply is not important, but you may change your opinion after reading this article.

Further reading: Computer configuration generally refers to the high-grade degree and cost performance of computer hardware accessories, and the performance of computers mainly depends on.

(1)CPU: determines the running speed, such as Celeron D2.66G, where "2.66G" refers to its running speed, but the unit "g" here is different from the hard disk's "g", not the size, and the CPU's "g" is the frequency, that is, it can run 2.66G times per second.

(2) Motherboard: determines the running speed and stability. Due to the different chips used in the motherboard, it can be divided into many types, such as 845, 865, 895, 8 15, etc.

(3) Hard disk: determines the speed and size of reading and storing data, such as 80G/7200/0.8M, where 80G is the size, 7200 is the rotation speed, and 0.8M is the cache of hard disk, which also determines the speed. (4) Graphics card: It determines the display effect and speed, and its performance index generally depends on its memory and number of bits, which is what people often say.

1, CPU, this mainly depends on frequency and secondary cache. The higher the frequency, the larger the secondary cache and the faster the speed. In the future, CPU will have three-level cache and four-level cache, which will affect the response speed.

2. memory. The access speed of the memory depends on the interface, the number of particles and the storage size (including the interface of the memory, such as SDRAM 133, DDR233, DDR2-533, DDR3-800). Generally speaking, the larger the memory, the stronger the data processing ability and the faster the speed.

3. Motherboard, mainly processing chips. For example, the processing ability of notebook i965 is stronger than that of i945, and the data processing ability of i945 is stronger than that of i9 10, and so on.

4, hard disk, hard disk in daily use, less consideration, but there are some effects, the first is the speed of hard disk (divided into high-speed hard disk and low-speed hard disk, high-speed hard disk is generally used in large servers, such as: 10000 rpm,15000 rpm; General computers (including notebook computers) use low-speed hard disks, desktop computers generally use 7200 rpm, and notebook computers generally use 5400 rpm, mainly because of power consumption and heat dissipation.

The speed of the hard disk varies with different interfaces. Generally speaking, it is divided into IDE and SATA (also known as serial port) interfaces. In the past, hard disks were mostly IDE interfaces, and the access speed was slower than SATA interfaces.

In recent years, with the development of the hard disk market, the cache has increased from 2M to 8M or even more. Just like CPU, the bigger the cache, the faster.

5. Graphics card: This is directly related to the response speed of running super-large program software, such as running CAD2007, 3DStudio, 3DMAX and other graphics software. In addition to the distinction of hardware levels, graphics cards also have the technology of "* * * with video memory", which is different from general chips with video memory, that is, the technology of "* * * with video memory" needs to be read from memory to handle the requirements of corresponding programs. Or some people call it dynamic memory. This technology is more used in notebook computers.

6, power supply, this is OK as long as the power is enough and the stability is good.

7. Monitor: The interface between the monitor and the motherboard has the same influence, but people generally don't care too much.
