How to check the configuration of your love machine is good or bad

  

For many newcomers, how to check the quality of their computer configuration is a more tangled problem, and sometimes there are some misunderstandings. In order to let everyone have a deeper understanding of the hardware, the following is for everyone. Dedicated a little about your own.

Motherboard

A look at the number of CPU cores

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

Second look at the production process

At present, the 45nm CPU has been popularized, the previous generation is 65 nanometers, and the older 90 nanometers (not much seen). The manufacturing process of 45 nm refers to the width of the wire connection between the transistor and the transistor (referred to as the line width). Simply put, it is possible to "squeeze" more transistors and more transistors on the same area of ​​the chip. What brings is higher performance. Even if the number of transistors does not increase, the area of ​​the chip can be reduced accordingly, so that power consumption and temperature can be reduced a lot.

Three look at the size of the secondary cache

CPU is the fastest in the computer "run", sometimes because it runs too fast, causing other hardware such as memory to follow On his rhythm, so the CPU manufacturer introduced the cache this thing. Look at the size of the secondary cache to determine the quality of the CPU is mainly for Intel's CPU, because Intel's CPU depends on the secondary cache is relatively large, INTEL's CPU secondary cache is mainly used to store data, the first level cache is stored The address of the second-level cache, in the first-level cache, the data is compiled with a number such as AZ. When the CPU needs to retrieve the data, it can directly retrieve the data number from the first-level cache. For example, it is like two levels. The cache is the content of a book, the first level cache is the directory of this book, which is why INTEL's CPU L2 cache is particularly large, and the L1 cache is particularly small. AMD's CPU design is different from Intel. AMD's CPU level 1 cache is used to store the most commonly used data, and Level 2 cache is the more commonly used data, so AMD's CPU level 1 cache and level 2 cache are similar. Big. In theory, Intel's CPU is more efficient. When the CPU needs to retrieve some data, it can directly retrieve the number.


Four look at the main frequency

In the case where the first three are the same, you can judge the quality of the CPU by the frequency of the main frequency, most of the CPU frequency is From 2.0GHz to 3.0GHz, the highest is now no more than 4.0GHz, because the main frequency is too high, the heat and power consumption will be correspondingly larger.

Graphics Card:

At present, the manufacturers of graphics chips (GPU) on the market have NVIDIA and ATI, which are the N and A cards that people usually say. The GPU's position on the graphics card is equivalent to the CPU in the computer. Geforce and HD are often mentioned as a series of NNIDIA and ATI. Geforce has been around for ten generations. Generally speaking, it is not necessary to add this when using the graphics card model. There are too many manufacturers of graphics cards, but they all use the above two chips.

Look at the quality of the graphics card mainly depends on [graphic chip, SP unit, manufacturing process, core frequency], [memory frequency, memory bandwidth, memory speed, memory capacity] (ranked in order, the more the front Important), the specific point depends on the work of the graphics card.

Motherboard:

Motherboard mainly depends on the chipset. There are not many chipsets common on Intel platforms, such as P55, P45, P43, etc. with integrated graphics. Commonly there are G41, G43, G45, and the set is the beginning of G. The main board of the AMD platform is now the AMD 7 series chipset, and it is also equipped with G, such as 780G, 785G, 790G, 790GX. As with the graphics card, it is also necessary to look at the motherboard to see how it works.


Others:

The hard disk speed is now 7200 rpm on the desktop, and the notebooks are 5400 rpm.

The memory frequency is mainly to meet the bandwidth of the CPU. For example, to use the E5200, the FSB (front-side bus frequency) of this CPU is 800MHz, the bandwidth is 800MHz× 64÷ 8=6.4GB/s, if the CPU does not If you are overclocking, you can use the memory of DDR2 800MHz frequency to meet the bandwidth requirement of the CPU. If the CPU uses the E8400, its FSB is 1333MHz. When using the memory with a DDR2 800MHz frequency, the CPU performance cannot be fully utilized. At this time, it is necessary to rely on dual channels, and two 667MHz frequency memory groups have dual channels. Just meet the needs of the E8400, if overclocked, it will be equipped with two 800 memory sets dual channel.

Hey, by the way, Windows 7 optimization masters and Rubik's Cube can read the life of the hard disk.
