Is there a big or small graphics card? What is the use of the graphics card memory size

No, there are AGP and PCI, and now they are generally PCI-Express. There are no big or small ones.

There is no difference between big and small.

There are only slot types.

At present, there are generally two types: AGP and PCI-E.

A good graphics card may be a little longer and a little thicker.

Your worries are unnecessary.

The chassis can't be designed so that the graphics card can't fit in.

The size of the graphics card is different, generally the larger the volume of the video memory,,, the smaller the size.

But the socket, the VCA is the same arrangement, and the PCI is the same

There are only two interfaces for the graphics card, AGP and PCI-E.

There is generally no difference in size.

At the very least, a decent chassis will definitely be able to fit the graphics card.

Upstairs is **, and there are Trojan horses and viruses.

There are different models of graphics cards.

PCI E and AGP graphics cards.

There is only a difference in model, there is no difference in size.

The height of the general graphics card is the same. There is a special graphics card, called a half-height graphics card, and the height of the PCB board is only the same as that of an ordinary one. As for the length, each graphics card may be different, generally the more high-performance the graphics card, the longer the length will be.

It doesn't matter how big or small the general ATX case is, ordinary graphics cards can be installed, but if it is the case of an ultra-thin brand machine (such as Dell), it can't fit in.

It's basically all the same.

Like a computer's memory, video memory is the part that is used to store the graphic information to be processed. The picture we see on the display is made up of pixels, and each pixel controls its brightness and color with 4 to 32 or even 64 bits of data, which must be saved through video memory, then handed over to the display chip and CPU for configuration, and finally the calculation result is converted into a graphic output to the display.

Video memory, like motherboard memory, performs the function of storage, but it stores information about each pixel that the graphics card outputs to the display. Video memory is a very important part of the graphics card, after the graphics chip processes the data, it will save the data to the video memory, and then the RAMDAC (digital-to-analog converter) will read the data from the video memory and convert the digital signal to an analog signal, and finally it will be displayed on the screen.

Due to the role that the graphics presence plays on the graphics card, it is clear that the speed and bandwidth of the video memory directly affect the overall speed of the graphics card. As a memory, video memory has also gone through multiple stages of development like motherboard memory, and it can even be said that the development of video memory is more active than motherboard memory, and there are more varieties and types.

The difference in the size of the graphics card's video memory:

1. The maximum resolution that can be supported is different: the video memory capacity is the capacity of the local video memory on the graphics card, which is one of the key parameters for selecting the graphics card. In terms of the maximum resolution of the graphics card, the maximum resolution is directly related to the video memory to a certain extent, because the data of these pixels is initially stored in the video memory, so the video memory capacity will affect the maximum resolution.

2. The amount of data that can be cached is different: as the processing power of the display chip becomes more and more powerful, especially the current large-scale 3D games and professional renderings need to temporarily store more and more data, and the required video memory capacity is also increasing, and the video memory capacity will also affect the performance of the graphics card to a certain extent.
