What is difference between discrete graphics and integrated graphics?
Our friends who often use computers for games and watching videos should know how important graphics cards are for computers. A good graphics card can let us enjoy excellent gaming experience and video in games and watching videos. However, many friends may not know that our computer graphics cards are divided into discrete graphics cards and integrated graphics cards, so what is a discrete graphics card and what is an integrated graphics card? What is difference between discrete graphics and integrated graphics? Let's learn together below!
1. Embedded Graphics
An integrated graphics card is a special type of graphics card that does not normally have video memory, but uses a portion of system's main memory as video memory, and its specific amount is automatically and dynamically adjusted by system according to need. Since integrated graphics card is on motherboard, work of heat dissipation is also done by motherboard, and effect is not perfect. With prolonged use, heat dissipation becomes main problem. So main problem is heat dissipation. However, for home users who do not freeze for a long time and play large-scale games, built-in graphics card can fully meet the needs of users. If you're only considering price, you only need integrated graphics.
2. Independent video card
Discrete graphics card is called independent graphics card, which refers to graphics card, which is an independent board and must be inserted into corresponding interface of motherboard. Discrete graphics cards are divided into integrated discrete graphics cards and external graphics cards. The discrete graphics card has independent video memory, does not take up system memory, and is technically ahead of integrated graphics card, which can provide better display effect and performance. As an important part of a computer, a discrete graphics card is very important for those who love to play games and do professional graphic design. At present, main suppliers of graphics chips for civilian video cards are AMD (formerly ATI) and nVIDIA.
3. The difference between an integrated graphics card and a discrete graphics card
Integrated graphics card means that display chip is embedded in chipset. The motherboard using this chipset can perform normal display functions without a separate graphics card, to meet general home entertainment and business applications, and save users purchase of graphics. cards. The chipset in which graphics card is integrated is also often referred to as an integrated chip, and such a motherboard is often referred to as an integrated motherboard.
Integrated graphics cards typically do not have video memory and use a portion of main memory of system's integrated graphics card as video memory. The specific amount is usually automatically and dynamically adjusted by system according to needs. Obviously, if you use integrated video card to run programs that require a lot of video memory, impact on entire system will be more obvious, in addition, frequency of system memory is usually much lower than frequency of discrete graphics. card, so performance of integrated graphics card is inferior to that of discrete graphics card.
The discrete graphics card is replaceable. If a used discrete graphics card doesn't meet your needs, you can buy a more powerful one. Of course, you should also pay attention to matching of corresponding accessories. Just upgrade your graphics card and ignore other accessories.
In terms of performance and power consumption, integrated graphics card is average in performance, but in principle it can handle some everyday tasks, and its heat dissipation and power consumption are lower than those of discrete graphics cards. Despite high performance of independent graphics card, heat dissipation and power consumption are relatively high. Discrete graphics cards are better than integrated graphics cards in terms of 3D performance.
What needs to be explained is that if users want to play games, they should choose a discrete graphics card so that game does not freeze, and if theypania, they should choose an integrated graphics card. which is cheap. It is recommended that users can choose according to their needs!
The above pair is the introduction of a discrete graphics card and an integrated graphics card. Have you already studied it?
