What are the classifications of graphics cards? What are the types of graphics cards?

At present, there are two main graphics cards. NVDIA and ATI (acquired by AMD but retaining its brand); There are many card models of NV, and the full line of PCI-E series models range from 7100 7300 7600 7800 84000 8500 8600 8800, which is also divided into LE, GS, GT, GTX; There are fewer ATI models, and the full line of PCI-E series models range from X300 X500 X1300 X1600 X1950 HD2400 HD2600 HD3850, which are also divided into ordinary version, Pro version, and TX. If you want to know more, have time to go to Zhongguancun** to have a look.

Let's talk about the classification of graphics cards and how to choose the right one for you.

According to the type, it can be divided into two types: integrated graphics cards and discrete graphics cards. Integrated Graphics:

Completely free (free when you buy a motherboard or CPU, integrated into the motherboard or CPU), low power consumption, poor performance. Discrete graphics card: more expensive, higher power consumption (roughly proportional to performance), stronger performance (depending on the grade of the graphics card, of course, if you buy a pure impotent discrete graphics card, of course, the performance will not be strong).

Graphics cards are AMD, NVIDIA, Intel, etc. according to brands, independent graphics cards, integrated graphics cards, core graphics cards, etc., high-end graphics cards, mid-range graphics cards, low-end graphics cards, etc. according to performance, and ordinary graphics cards, professional graphics cards, etc.

The classification of graphics cards depends on how they are divided, according to the manufacturer, there are Nvidia and AMD. In addition, there are discrete graphics cards and integrated graphics cards, as well as different divisions of video memory.

There are two classifications of graphics cards: integrated graphics and discrete graphics.

There are two types of discrete graphics cards: N-card (NVIDIA) and A-card (AMD).

Integrated graphics card, core graphics card, consumer-grade discrete graphics card, professional-grade discrete graphics card, professional computing card.

Graphics cards are mainly divided into two mainstream brands: AMD and NVIDIA.

Integrated graphics and discrete graphics.

The graphics card is one of the most basic components of the personal computer, which is used to convert the display information required by the computer system to drive the display, and provide progressive or interlaced scan signals to the display to control the correct display of the display, and is an important component to connect the display and the motherboard of the personal computer. So what are the classifications of graphics cards?

1. Integrated graphics card: The integrated graphics card is to make the display chip, video memory and related circuits on the motherboard, and integrate it with the motherboard; There are separate graphics chips for integrated graphics, but most of them are integrated into the motherboard's northbridge chip; Some motherboard integrated graphics cards also have separate video memory installed on the motherboard, but its capacity is small, and the display effect and processing performance of the integrated graphics card are relatively weak, and the graphics card cannot be upgraded hardware, but the potential of the graphics chip can be tapped by adjusting the frequency of CMOS or flashing in a new BIOS file to achieve software upgrades.

2. Independent graphics card: Independent graphics card refers to the display chip, video memory and its related circuits are made separately on a circuit board, which is self-contained and exists as an independent board, which needs to occupy the expansion slot of the motherboard (ISA, PCI, AGP or PCI-E).

3. Video memory: Video memory is the abbreviation of display memory (similar to the memory of the motherboard). Its main function is to temporarily store the data to be processed by the display chip and the data that has been processed.

The more powerful the graphics core, the more memory is required. In the past, the video memory was mainly SDR, and the capacity was not large. Most graphics cards on the market use GDDR3 memory, and today's graphics cards use GDDR4 or GDDR5 memory with better performance.

4. Graphics card BIOS: The graphics card BIOS (similar to the BIOS of the motherboard) is mainly used to store the control program between the graphics chip and the driver, and also stores the model, specification, manufacturer and factory time of the graphics card. When the computer is turned on, this information is fed back to the screen by displaying a control program within the BIOS.

While early display BIOS were solidified in the ROM and could not be modified, most graphics cards used high-capacity EPROM, the so-called FlashBIOS, which could be rewritten or upgraded through a dedicated program.

Graphics cards can be divided into discrete graphics cards, integrated graphics cards, and core graphics cards. The graphics card name is preceded by HD, Readon, X, etc., these are A-cards; The name is preceded by GeForce, GTX, etc., and these are N cards. Suffocation.

A discrete graphics card is a graphics card chip, video memory, and other circuits placed on a separate circuit board, which can automatically move between the computer and the computer.

The integrated graphics card is to put the graphics chip, video memory and related circuits all in the motherboard, so that the motherboard and the graphics card become a whole, so it cannot be moved at will.

The core graphics card integrates the graphics core and the processing core all on a single substrate, so that a complete processor can be formed.

Data expansion: The process of opening the discrete graphics card on the computer is as follows - first turn on the computer to enter the desktop, then right-click on the desktop, click the "NVIDIA Control Panel" option in the pop-up menu, and then the NVIDIA settings menu will pop up, click the "Manage 3D settings" button, you will see the global use of integrated graphics or independent graphics options, after selecting the discrete graphics card, the system will use the discrete graphics card when performing tasks.

In addition, users can also choose to add their own programs.

Advantages of independent graphics card: Separately installed video memory, generally does not occupy system memory, and is technically much more advanced than integrated graphics card, but the performance is certainly not inferior to that of integrated graphics card, and it is easy to upgrade the hardware of the graphics card.
