What are the main types of graphics cards used in computers today?

PCI Express is a new generation of bus interfaces, and graphics cards with such interfaces have been available since 2004. As early as the spring of 2001, at the "Intel Developer Forum", Intel proposed to replace the PCI bus and the internal connection of a variety of chips with a new generation of technology, and called it the third generation of IO bus technology. Subsequently, at the end of 2001, more than 20 industry-leading companies, including Intel, AMD, Dell, and IBM, began to draft specifications for the new technology, which was completed in 2002 and officially named PCI Express.

The theoretical speed is more than 10Gbit, so in this gap, AGP has been hit by PCIe, but just like PCI replaces ISA, it takes a certain amount of time, and it must be 915 or more North Bridge to support PCIe, so it is foreseeable that PCIe will take a long time to replace AGP.

Cultivators. Outside of Yingchi, it is either a miscellaneous brand or a scolded brand (such as Tongde), make a mistake? Since.

There are many brands, so I won't introduce them one by one!

There are two kinds of mainstream chips!

NV's and ATI's!

Among them, the mainstream models of NV are: 8500GT, 8600GT, 8600GTS, 9600GT, 9600GSO, 8800GS, 8800GT!

The mainstream models of ATI are (because I prefer NV this one is not very concerned): 3650, 3690, 3850, 3870, 3870 x2!

The performance is from weak to strong, and so is the price! Only the current mainstream models are listed, and the previous obsolete ones are not listed! ）

1. According to independence, there can be independent graphics cards and integrated graphics cards

A discrete graphics card is a graphics card that is inserted in the expansion slot of the motherboard, and its performance is generally more powerful than that of an integrated graphics card.

The integrated graphics card is a display chip integrated on the motherboard, or integrated in the CPU like the Intel Core I series, which is generally not very powerful and can only meet the needs of general applications;

2. According to the use, there are ordinary graphics cards and professional graphics cards

An ordinary graphics card is a graphics card that is generally bought on the market to watch movies and play games;

A professional graphics card is a graphics card that is used in graphic design.

Graphics cards are divided into integrated graphics cards and discrete graphics cards:

The advantages of integrated graphics cards: low power consumption, low heat generation, and the performance of some integrated graphics cards is comparable to that of entry-level discrete graphics cards, so there is no need to spend additional money to buy graphics cards.

Disadvantages of integrated graphics cards: The performance is relatively low, and it is solidified on the motherboard or CPU, and it cannot be replaced by itself, and if it needs to be replaced, it can only be replaced with the motherboard or graphics card at one time.

Advantages of independent graphics card: Separately installed video memory, generally does not occupy system memory, and is much more advanced than integrated graphics card in technology, which can get better display effect and mega performance than integrated graphics card, and is easy to upgrade the hardware of graphics card.

Graphics card (videocard, graphicscard) is the full name of display interface card, also known as display adapter, is one of the most basic configuration and important accessories of a computer. As an important part of the computer host, the graphics card is a device for the computer to convert digital-to-analog signals, and undertakes the task of outputting and displaying graphics. The graphics card is connected to the motherboard of the computer, which converts the digital signal of the computer into an analog signal for the display of the display, and the graphics card still has image processing capabilities, which can assist the CPU to work and improve the overall running speed.

For people who are engaged in professional graphic design, graphics cards are very important. The manufacturers of graphics chips for civil and military graphics cards mainly include AMD and NVIDIA. Today's TOP500 computers all contain graphics card computing cores.

In scientific computing, graphics cards are referred to as display accelerator cards.

Graphics cards are divided into independent graphics cards, integrated graphics cards and core graphics cards, and the differences are: different properties, different graphics cores, and different power consumption.

From the bus interface, there are ISA, PCI, AGP, PCI-E, and now the mainstream graphics card is PCI-E.

In terms of chip brands, the mainstream graphics cards are NVIDIA, AMD, and some less common ones like Matrox, S3 (now acquired by VIA) and so on.

In terms of the independence of the graphics card, there are discrete graphics cards and integrated graphics cards.

In terms of the algebra of graphics cards, there are DirectX1 graphics cards, DX2, DX3, DX5, DX6, DX7, DX8, and DX11 graphics cards, and now the mainstream ones are DX10 graphics cards and DX11 graphics cards.

A graphics card is a graphics card!

The role of the graphics card (also known as the display card) is to control the display mode of the display. There are also control circuits in the display, but it is the graphics card that plays the main role. In terms of bus type, there are four types of display cards: ISA, VESA, PCI, and AGP.

Nowadays, PCI graphics cards have become very common and are widely used in 486 and 586 computers; The more high-end ones are AGP graphics cards, and most of the computers of the Pentium II class use AGP graphics cards.

In the early days, the role of graphics chips was relatively simple, everything was handled by the CPU, they only played a role in transmitting display information, which reduced the display speed and increased the workload of the CPU. With the advent of the graphics operating system Windows, this drawback has become more and more serious, so the graphics acceleration card has appeared. Nowadays, most graphics cards have acceleration chips, and these chips have graphics processing capabilities.

It's not that there is no graphics card If your computer can display it, it means that you are using an inherited graphics card, if it is independent, you can see that your display device is on your AGP interface, hehe, if there is no graphics card, your computer can't display it, hehe.

In terms of interfaces, the current mainstream is the graphics card with PCI-E interface. The previous ones had AGP interfaces and PCI (antique) interfaces. It's all out.

In terms of usage categories, there are professional graphics cards and gaming graphics cards (that is, those used by ordinary users. As the name suggests, professional graphics cards are very capable of drawing, especially 3D rendering, but they are not capable of 3D games. The opposite is true for gaming graphics cards.

The game is powerful, but not the drawing rendering 3D design aspect....

There are only 2 manufacturers from the main chip: NVIDIA and the company have deep pockets, all kinds of game support, good compatibility, and strong drivers, AMD's graphics card was acquired by ATI company, focusing on cost performance, but its driver is weaker, and the compatibility is not so good compared to N card.
