1. Right-click Computer and left-click the Properties button.

2. You can see some vague information here. To view the "Graphics Card" information, click the "Device Manager" option on the left side of the page.

3. There are all kinds of computer devices in the device manager, and we found the "display adapter".

4. Then double-click the display card, and the model and information of the display card will appear below.

Graphics card (full name: display interface card, also known as display adapter) is one of the most basic accessories of computer, which is mainly divided into integrated graphics card, independent graphics card and core graphics card. As an important part of the computer host, the graphics card is the equipment for digital-to-analog signal conversion, which undertakes the task of outputting and displaying graphics. In scientific calculation, the graphics card is called the display accelerator card.

Advantages of integrated graphics cards: low power consumption and low calorific value. The performance of some integrated graphics cards can be comparable to that of entry-level discrete graphics cards, and there is no need to spend extra money on discrete graphics cards.

Disadvantages of integrated graphics card: the performance is relatively low, solidified on the motherboard or CPU, and cannot be replaced. If it must be replaced, only the motherboard can be replaced.

Independent graphics card means that the display chip, video memory and its related circuits are made on a circuit board and exist as independent cards, which need to occupy the expansion slot (ISA, PCI, AGP or PCI-E) of the motherboard.

Advantages of discrete graphics card: it has independent video memory, generally does not occupy system memory, is much more advanced than integrated graphics card in technology, can obtain better display effect and performance than integrated graphics card, and it is easy to upgrade the hardware of graphics card.

Disadvantages of discrete graphics cards: the system power consumption increases, the heat generation is also large, and it needs to spend extra money on graphics cards, which takes up more space (especially notebook computers).

Due to the different performance of graphics cards, the requirements for graphics cards are different, so now independent graphics cards are actually divided into two categories, one is entertainment graphics cards specially designed for games, and the other is professional graphics cards used for drawing and 3D rendering. At present, the strongest discrete graphics cards for games are GTX690 from NVIDIA and HD7990 from AMD, and Q6000 from NVIDIA is used for 3D drawing.
