Graphics card configuration
As an important part of computer host, graphics card is very important for people who like to play games and engage in professional graphic design. The graphic chip suppliers of civil graphics cards mainly include ATI and nVIDIA. (ATI has been acquired by AMD and renamed AMD)
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.
In 2020, the highest-end graphics cards on the market are generally considered as NVIDIA 2080ti and NVIDIA Titan X.
display 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 you 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. Display cards range from early monochrome display cards, color display cards and enhanced drawing display cards to VGA (video graphics array) display drawing number cards.
The maximum pixel filling rate is the 3D clock multiplied by the number of rendering processes. For example, NVIDIA's GeForce 2 GTS chip has a core frequency of 200 MHz and has four rendering pipelines, each of which contains two texture units. Then its filling rate is 4x2 pixels x2 billion/sec =16 billion pixels/sec. The pixels here make up the picture seen on the display screen. At the resolution of 800x600, there are 800x600 = 480,000 pixels, and so on, at the resolution of 1024x768, there are1024x768 = 786,432 pixels. When playing games and using some graphics software, the resolution is often set. The higher the resolution, the more pixels the display chip will block, so the filling rate is of great significance to measure the performance of a graphics card. The above calculation shows that the filling rate of GTS is 65.438+0.6 billion pixels per second, and then look at MX200. Its standard core frequency is 175, and there are only two rendering pipelines, so its filling rate is 2x2 pixels.
