Graphics type

There are two types of graphics cards available for desktop computers on the market today: discrete graphics and integrated graphics.

The discrete graphics card has its own display chip and memory particles, and does not occupy CPU and memory. The advantage of the discrete graphics card is that the data processing does not require the CPU to help complete the release of CPU usage, and the native GPU can handle the data with its own 3D performance. The disadvantage is that the performance of the discrete graphics card is strong, but the heat output and power consumption are relatively high. It requires extra investment to purchase the graphics card, and the price of the good graphics card is very high.

The integrated video card refers to an integrated display chip in the chip set. The motherboard using this chip set can realize ordinary display functions without requiring a separate video card to meet the general home entertainment and commercial applications, and save users the expense of purchasing the video card. The integrated graphics card does not have video memory, and uses part of the main memory of the system as video memory. The specific number is generally dynamically adjusted by the system as needed. Obviously, if you use an integrated graphics card to run a program that requires a large amount of memory, the impact on the entire system will be obvious. In addition, the frequency of system memory is usually much lower than that of a discrete graphics card, so the performance of integrated graphics is much lower than that of a discrete graphics card.

For the average user, generally speaking, if you do not do 3D graphics design or other professional use, the performance of integrated graphics and discrete graphics is basically the same, the general family can not feel what they are different, integrated graphics The performance is completely suitable for their daily office entertainment, and the excellent compatibility and stability, moderate price, and constant optimization of technology are the advantages of integrated graphics. Discrete graphics cards are only necessary for professional users and game enthusiasts who really need high-speed, high-quality displays.
