How to look at Processor CPU and video card

We just know the CPU frequency, the core number, two cache and other parameters can be, the higher the frequency of high-frequency operation, the core number of the more the better, two-level cache the more about good.

For graphics cards too, we just need to know the graphics card frequency memory and brand, the main frequency is also the speed of the graphics card, the higher the better, video memory is the display performance of the graphics card, the greater the performance of the cards obviously, the better the brand good technology, mature, so that the graphics card compatibility is better, running more stable. If you want to know the specifics of your own computer configuration can be installed by the master and other testing software to detect their own computer configuration.

Let's take a look at what the CPU has in particular.

The CPU is the abbreviation of the central processing Unit, which we call the CPU, which contains the logical operational units, control units, and storage units. There are registers in the logical Operation Unit and control unit, which can temporarily store the data of CPU operation.

1, CPU Frequency

CPU's main frequency is the CPU clock frequency, that is, the work is the most frequent (CPU frequency is less than this value), the following figure shows the CPU frequency is 2.7GHz, a general clock cycle to complete the instructions when certain, the higher the frequency is the faster the operation. Algorithm: the clock frequency = FSB x magnification.

2, CPU FSB.

CPU FSB is the CPU's external clock frequency, motherboard and CPU standard external frequency has 66mhz,100mhz and 133MHz several, the same FSB better CPU performance will be better, the motherboard can regulate FSB, the same motherboard regulation of the higher the better, can also overclocking use.

3, the CPU magnification.

Magnification is the ratio between CPU frequency and FSB.

4, CPU interface

CPU interface is the link between the pig CPU and the motherboard, mainly has the card interface (SLOT) and the mainstream pin-type interface. At present, most are pin-type interfaces.

5, the CPU cache.

The cache is divided into two types of L1 cache (internal or first-level caching), L2 cache (external cache or level two cache), and the greater the cache, the better the CPU performance.

6, the CPU's multimedia instruction.

In order to improve the CPU performance in 3D, multimedia cover, many processor instructions have been developed, they are mainly for image processing, floating-point operations, 3D operations, such as to strengthen the role.

7.CPU manufacturing process.

Now the CPU manufacturing process is nanometer level, now the minimum level is 28NM, the smaller the size of the unit area on the integration of the more electronic components, not only can reduce CPU volume can also increase CPU performance.

8, CPU operating voltage.

CPU operating voltage is smaller, the smaller the CPU power consumption, the smaller the production of heat, we all know that too much temperature will affect the CPU's calculation speed.

For us just with the computer, just need to understand the CPU's main frequency, the core number, and the cache can be, there is no need to understand so fine, can install a master and other testing software can see your computer hardware configuration.
