When it comes to computer performance, what determines the performance of a computer?

These two accessories alone cannot completely judge the advantages and disadvantages of the computer, and the graphics card, an important accessory, is not clearly written. CPU,It's E4400,It can only be said to be a little better than the entry-level E2000 series,It's not comparable to E5200,1G memory is small,It's better to add 2G。 If there is a discrete graphics card, and it is 8600GT, HD2600 or above, the performance of the whole machine is OK, if the independent graphics card is lower than the above graphics card, or the integrated graphics card, the performance of the whole machine is weak.

In general, it's not too rubbish, it's not much better, it's probably low-end. If you want to get better performance, you can add 1G memory of the same specification, and add an HD4650 to the graphics card.

Where is there garbage? Who said rubbish? Stand out! If 1G memory is XP, I don't think it's enough to stand up for the theory!

Even if it's 1G memory is less (relatively mainstream),But smooth running system,And generally more software is absolutely no problem,Personally,This configuration is absolutely not garbage,If someone says so,Call him and me theory!

This kind of performance is good· · For home users·· That's a pretty good configuration...

You like this, it is recommended to configure the memory on 2G...

Basically you can do a lot of things with your computer...

It's okay.,Don't play any games.,It's nothing.,For example, learn what c.,C++ or something.,The configuration is still high.,That's good.,Hehe.。

The Core doesn't have that model 4400 that you said....

The main frequency of 2G is really not high. 1GB of RAM isn't ideal either.

The performance is average, if you buy it now, it's not worth it.

What is the model?

1G memory is ordinary.

The assembly is still the brand, the brand description brand, if the assembly, the individual parts are explained.

Computer configuration generally refers to the high-end degree of hardware accessories of the computer, cost performance, etc., and the performance of the computer is mainly determined by the following accessories:

1) CPU: Determine the running speed, such as Intel Pentium Dual-Core E6300 (box), 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 "GHz" is the frequency, that is, the computer configuration can be calculated per second.

2) Motherboard: Determine the speed and stability of the operation, due to the different chips used in the motherboard, it can be divided into many kinds, and the latest chipset has the following types: Intel H55 | amd 880g | amd 785g | intel p55 |AMD 790GX by motherboard interface:

lga 775 | lga 1366 | lga 1156 | socket am2/am2+ |socket am3 and so on.

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 configure the computer with 2G RAM or more. XP system, 1G of memory is also enough, but the new Win7 operating system needs at least 2G of memory.

For example, Kingston 2GB DDR3 1333.

The performance of the computer is a relatively general statement, and the performance of different people who need it is different, generally speaking, there are the following aspects of performance: CPU performance, disk performance, display performance, etc.

CPU performance: mainly the computing power of the CPU, it is an important indicator to measure the performance of the computer. The powerful computing power of the CPU is mainly used to process data, such as processing the weather by calculating the weather according to the data model and formula.

Disk performance: or IO performance, it is an indicator of the computer's data input and output ability, using a person as an analogy, it is said that this person speaks fast; The input and output capabilities are reflected in the copying and transmission of files, for example, the interface used to copy files must be more than ten times faster.

Display performance: It mainly refers to the performance of the graphics card and the display, the performance of the graphics card is strong, you can make the picture of some 3D games more delicate, real, and the display performance is good, that is, the picture it can display is more real, more delicate, and more pleasing to the eye.

The performance of a computer mainly depends on: word length, operation speed (the number of instructions that can be executed per second), the capacity of internal memory, the capacity of external memory, the speed of IO, video memory, hard disk speed, and the clock frequency of the CPU (the clock frequency at which the CPU core works).

There are three main things that usually affect the performance of a computer: CPU, memory, and graphics card.

Because the technical improvement of the hard disk is not very obvious, the impact on the performance is relatively small compared to the above 3 major pieces Of course, if you use an SSD, the data transfer performance will be greatly improved

1.CPU is the first processor, as the name suggests, its role directly affects the computing performance of the entire computer, but the current software and games for ordinary people, the performance of the CPU has risen to a certain height, so in general, the gap between the mainstream CPU and the high-end CPU is not very large, for games, the impact of the main frequency of the CPU is greater. This is also the reason why the performance of high-end dual-core games is stronger than that of low-end quad-cores.

Example: Intel Core 2 Duo E8400

2.Memory,Now the memory ** is cheap,The mainstream is directly on 2G,But if you go on4G, it doesn't matter,But for 32-bit operating systems,Memory addressing ability is limited,At most, it can only identify the capacity of 3G,That is to say, the extra 1G is free,The system can only call 3G memory,But if you install a 64-bit operating system,It's another matter。 In terms of current large-scale 3D games, upgrading from 1G memory to 2G is still a significant improvement in performance.

Upgrading memory is also the easiest, most straightforward, and most cost-effective upgrade solution.

3.Graphics card,The impact on game performance,I think the graphics card can be ranked before the CPU and memory,It is mainly responsible for game graphics rendering,In the same case of mainstream CPU+2G memory,The gap between the low-end graphics card and the high-end graphics card is very large

In terms of game performance alone, the arrangement of the above 3 major items should be: graphics card, CPU, and memory.

Display. Graphics card (both discrete and integrated).

Mainboard. cpu

Hard disk. Memory.

Chassis. Speakers.

Mouse. Keyboard.

Optical storage. Power supply.

Radiator. Mouse pad.

The division of performance should know what the strongest performance is, the computer that is overclocked to the limit is nothing more than powerful, and what is the core inside the processor? Single-core or multi-core? Manufacturing process technology?

What is the size of the front-side bus? What is the size of the L2 cache and the L3 cache? These are the main criteria for measuring the processor, the overclocking of the motherboard is nothing more than good, the materials used in the PCB board, the *** bad of the electronic components, and the heat dissipation of the north and south bridge chips?

How much does the interface extensibility? Is PCI-E16X a standard? Is there 1 or 2?

Rent Min Nai dual-channel memory must be supported, is the integrated sound card HD? How many PCI extension interfaces are there? How many SATA interfaces are there?

Does it have SATA2 functionality? What about the power supply? How powerful is the processor and how high is the memory available?

Most people in memory are in the problem of capacity, however, it is more important to have his memory particles, take care of the strong memory particles can achieve extremely fast clock sequences to keep the memory in a high-speed state, rather than blindly pursuing high-capacity memory, if the reading and writing ability does not change, it is useless. The graphics card is also in the core, the size of the video memory does not matter, how large is the bit width, how many fixed-point shaders, how many pixel fill rates, how many rendering pipelines? Is it a multi-core graphics card?

What about the cooling system? What are the materials used for PCB? These are the main ones.

If you think it's troublesome, we recommend that you use everest to test all the performance of your computer to the fullest, and it will give you a satisfactory answer.
