1)GPU
The full name is graphics processing unit, which is translated as "graphics processor" in Chinese. NVIDIA first proposed the concept when it released GeForce 256 graphics processing chip. GPU reduces the dependence of graphics card on CPU and does some work of the original CPU, especially in 3D graphics processing. The core technology adopted by GPU is hardware T&; Cube environment material mapping and vertex blending, texture compression and T& mapping, dual texture four-pixel 256-bit rendering engine, etc. , and hardware T &；; L technology can be said to be the symbol of GPU.
2) Graphics card
The basic function of the graphics card is to control the graphic output of the computer. Only when the video card is connected to the monitor can we see the image on the display screen. Graphics card consists of display chip, display memory, RAMDAC, etc. These components determine the output on the computer screen, including screen speed, color and display resolution. Graphics cards, from the early monochrome graphics cards, color graphics cards, enhanced graphics cards to VGA (video graphics array) display graphics array, are all IBM-led graphics card specifications. The resolution of VGA in text mode is 720*400, that in drawing mode is 640*480* 16, and that in color mode is 320*200*256. This 256-color display mode has become the * * * same standard for later graphics cards, so we generally call graphics cards VGA. Later, various display chip manufacturers made more efforts to improve the display capability of VGA, and some terms such as SVGA(SuperVGA) and XGA(eXtended Graphic Array) appeared. In recent years, display chip manufacturers have integrated 3D functions with VGA to become what we call 3D accelerator cards and 3D graphics cards.
