The structure of a general graphics card is as follows:
Capacitors: Capacitors are a very important component of the graphics card, because the quality of the display image mainly depends on the quality of the capacitors, and the quality of the capacitors directly affects the quality of the graphics card circuit.
Video memory: Video memory is responsible for storing various data that the display chip needs to process. Its capacity and performance directly affect the display effect of the computer. The new graphics cards all use DDR6/DDR5 video memory, and the mainstream video memory capacity is generally 2GB ~ 4GB.8G-80G
GPU and fan: GPU is the graphics chip , it is responsible for most of the calculation work of the graphics card , which is equivalent to the role of the CPU in the computer. The function of the GPU fan is to dissipate heat for the GPU.
Graphics card interface: Usually called golden finger , it can be divided into three types : PCI , AGP and PCI Express . PCI and AGP graphics card interfaces are basically eliminated. The mainstream graphics cards on the market use PCI Express graphics cards.
Peripheral interface: The peripheral interface of the graphics card is responsible for the output task of the graphics card. The new graphics card includes a traditional VGA analog interface and one or more digital interfaces (DVI, HDMI and DP).
Bridge interface: Mid-to-high-end graphics cards can support multiple work at the same time, and the bridge interface is connected through a bridge between them. display card rtx3090
