What is the difference between discrete graphics card and integrated graphics card

The difference between independent graphics card and integrated graphics card is: 1. Independent graphics card is an independent hardware device, while integrated graphics card is a part integrated on the computer motherboard; 2. Independent graphics card usually has stronger performance than integrated graphics card. graphics processing power and performance; 3. Independent graphics cards require additional power supply, while integrated graphics cards are relatively small and have low power consumption; 4. Independent graphics cards are slot-type hardware devices that can be replaced or upgraded, while integrated graphics cards Cannot be replaced or upgraded individually.

Discrete graphics cards and integrated graphics cards are two common types of computer graphics processing units (GPUs). They differ in the following aspects:

1. Physical independence : A discrete graphics card is an independent hardware device that has its own GPU, video memory and other related components, separate from the computer motherboard. The integrated graphics card is a part integrated on the computer motherboard and does not have independent video memory and components.

2. Performance: Discrete graphics cards usually have greater graphics processing power and performance than integrated graphics cards. Independent graphics cards use specialized GPU chips and have larger video memories, which can handle more complex graphics tasks, such as high-resolution games, 3D modeling, etc. Integrated graphics cards usually have lower performance and are suitable for general office applications and basic graphics processing needs.

3. Heat dissipation and power consumption: Due to its higher performance, discrete graphics cards usually require additional power supply and generate more heat. Therefore, discrete graphics cards usually require a separate cooling system to keep the temperature stable. Integrated graphics cards, on the other hand, are relatively small and consume low power, and are usually cooled by the cooling system of the computer motherboard.

4. Upgradeability and flexibility: Since the independent graphics card is a slot-type hardware device, users can replace or upgrade the independent graphics card to meet different needs. The integrated graphics card cannot be replaced or upgraded separately because it is already fixed on the motherboard.

It should be noted that choosing a discrete graphics card or an integrated graphics card depends on the usage scenario and needs. For professional users such as gamers and graphic designers who require high-performance graphics processing, a discrete graphics card may be more suitable. For general users and daily office use, integrated graphics cards are sufficient to meet the needs, and the cost is lower.
