What is a video card?

What is a graphics card, what is the role of the video card ?

Generally speaking, the graphics card is the control of computer graphics output, we like with the video hook, in fact, video is also a combination of pictures, through a more than a show of consecutive pictures of the combination of video.

So professional that the graphics card is a graphic adapter, we just know that the graphics card and computer display screen has a great relationship can be.

Professionally speaking, the video card is also known as an audio, video adapter, graphics card, graphics adapter and display adapter, and so on.

It is the connection between the host and the Monitor "bridge", the role is to control the graphics output of the computer, responsible for the CPU sent to the image data processing into the format of the display, and then sent to the monitor to form an image.

Graphics card mainly by the display chip (i.e. graphics processing chip graphicprocessingunit), video memory, digital analog Converter (RAMDAC), Vgabios, all aspects of the interface, such as the composition of several parts.

According to the structure of the graphics card can be divided into 2 categories, is often said that the independent graphics and integrated graphics 2 major categories.

Independent video card refers to the display chip, memory and its associated circuit on a single circuit board, self-contained and as a separate board exists, it needs to occupy the motherboard expansion slots.

The independent video card by the interface type is divided into ISA video card, PCI video card, AGP video card, PCI-E video card and so on, the ISA video card, the PCI video card has eliminated, the AGP video card also faces eliminates, the PCI-E video card is now the popular video card, its interface transmission speed is the current fastest

Integrated graphics, integrated graphics cards will display chips, video memory and related circuits are done on the motherboard, with the motherboard integrated;

Integrated graphics display chip has a separate, but now most are integrated in the motherboard of the North Bridge chip;

Some motherboards integrated graphics cards are also installed on the motherboard video memory alone, but its capacity is small, the majority of the current integrated graphics do not have a separate video memory, the need to use system memory to serve as memory, the use of the system automatically adjusted;

Cheng Xianka Display effect and performance is poor, can not be hardware upgrades to the graphics card;

The advantage is that the system consumes less power and does not have to spend extra money to buy graphics cards.

Because the independent video card has its own module, including their own cache, and a slightly better independent video card has a cooling fan, so we can see that the independent graphics card technology is also more advanced than integrated graphics, more than integrated graphics can be better display effect and performance, easy to carry out the hardware upgrade graphics;

Its disadvantage is that the system power consumption has increased, calorific value is larger, more suitable for the configuration display performance of the game user selection, and integrated graphics is mainly suitable for the computer performance requirements are not high, general access to the Internet, play a simple game user selection.

Is it OK for the computer to have no video card?

A: A lot of novice friends often say that there is no video card in the computer, in fact, is not a separate use of independent graphics card, but the motherboard has at least integrated graphics card, where the editor means that the computer can not have a video card.

The reason is that if the computer does not even have a graphics adapter, how can display the picture? So most friends said that the integration of the configuration is not a stand-alone video card, but selected the motherboard on the integrated graphics card.

Are all motherboards integrated with the first video card?

A: Not all motherboards have integrated graphics, the specific need to see the motherboard parameters

Is there an integrated video card in the motherboard on the computer that can also use a standalone video card?

A: Yes, when the integration platform computer can not meet the needs of the game may be separate with independent graphics upgrade performance, computer display performance will be greatly improved.

Introduction to Here, I believe that the graphics card should have a more comprehensive understanding, if you have any questions about the graphics card, welcome to connect us.
