Graphics card knowledge: What is the difference between set display, nuclear display, single display, and double display?

The graphics card believes that everyone will not be unfamiliar. In a computer, the graphics card controls the display of the display. If a computer does not have a graphics card, there will be no screen display. However, the graphics card can be divided into set display, nuclear display, single display, double display, then what is the difference between so many graphics card categories? The following small series will be directed at the rookie friend science.

"Graphic card" in English is called Video card, Graphics card, also known as display interface card or display adapter, is one of the most basic configuration, the most important and necessary accessories. In general, we say that the graphics card has integrated graphics, core graphics, discrete graphics, dual graphics (dual card crossfire) points, although they can be collectively referred to as graphics cards, but the corresponding meaning or form of existence is also different, below we Introduce separately.

Set display (integrated graphics, cheap)

Integrated graphics card refers to the graphics card integrated on the motherboard. The integrated graphics card has the advantages of low price, good compatibility and low upgrade cost.

Above: Integrated graphics (some old-fashioned motherboards are available, now eliminated)

However, the integrated graphics card does not have independent video memory. It takes up system memory and reduces the available physical memory of the CPU. In the process of interaction with the system memory, it will occupy the bus cycle and CPU cycle, so it will affect the performance of the computer in some aspects; Secondly, although the integrated graphics card has low upgrade cost, it is troublesome. To upgrade, the motherboard BIOS must be updated. Finally, the performance of the integrated graphics card is generally low. In the personal PC, it has been basically eliminated and has been replaced by the core graphics card.

Core graphics card: (low energy consumption, relatively cheap price)

The core graphics card is also a kind of integrated graphics card. It can be regarded as a special integrated graphics card. It is not integrated on the motherboard like the integrated graphics card, but integrated in the CPU, which brings better performance than the integrated graphics card.

Above: Core graphics card (CPU comes with it, in fact, the current smart phones are also CPU built-in GPU, which is the core graphics solution)

At present, Intel's Core processor, AMD's APU processor have built-in core graphics, and the performance is constantly enhanced, the high-end CPU built-in core graphics card can be comparable to some entry-independent graphics. Therefore, choose a built-in core graphics card computer, you can meet the needs of many online games without a separate graphics card. For example, APU computers generally locate intro game users, without the need for a separate graphics card, relying on the CPU built-in core graphics card to meet the needs of the public. demand.

Independent graphics (high cost performance, expensive)

Integrated graphics and core graphics card is basically to buy a motherboard or processor comes with a graphics card, equivalent to send, the price is relatively cheap. A discrete graphics card is different and it needs to be purchased separately. Need to be plugged into the motherboard's PCI graphics card slot, due to the large size, equipped with a separate cooling fan, the performance is naturally superior to the set and display.

The advantage of a discrete graphics card is that it has its own independent graphics memory and does not occupy system memory. Now, the average gaming computer is a discrete graphics card. Moreover, it can form multiple graphics cards inside the computer and has powerful image processing capabilities. However, the price of a discrete graphics card is more expensive. To upgrade, it is generally more expensive to purchase graphics cards. The upgrade is convenient but the cost is high, which is more suitable for mainstream game users.

Dual graphics (currently ubiquitous)

Dual graphics means that a computer contains 2 graphics cards, which are also common. For example, the CPU has built-in core graphics card, and the user separately purchased a separate graphics card. Such a computer is equipped with a dual graphics card. At present, most of the independent computers are equipped with dual graphics cards, and the computer will switch intelligently according to the needs.

Above: Discrete graphics

In addition, there is a situation where high-end gamers may be equipped with two high-end discrete graphics cards for combination. This situation is called dual-card crossfire. If you combine the core card built into the CPU, you can basically see it as a three-card card. It is.

Above: Double independence and crossfire (usually common in high-end fever game computer configuration)

In addition, some of AMD's APU core graphics cards can also be used in conjunction with discrete graphics cards to improve game performance.

Graphics card purchase suggestions:

For ordinary mass users who are not gamers, today's computer-integrated graphics cards have been eliminated. For beginners or users with less demanding games, a slightly better core graphics card can meet the daily needs without having to purchase a discrete graphics card. But if it is a game player, want to play all kinds of mainstream games, a mainstream independent graphics card is still essential, of course, in this case, most users of the computer are actually equipped with a core graphics card + independent dual graphics.

to sum up:

1. If you are browsing the web on a daily basis, playing web games, or working in the office, the general core graphics card can meet the demand, and you can save the budget for purchasing a discrete graphics card.

2, if it is a game user, especially 3D game enthusiasts, then a discrete graphics card is essential, of course, better CPU, such as the flagship APU, Intel six generations of i3 or higher processor itself built a good performance of the core graphics card, to meet CF , lol and other games without pressure, and later can increase the graphics card upgrade, this part of the user budget is limited, you can start not to buy a separate graphics card, you can purchase a graphics card upgrade later.

3, if you want to play large single game or medium and large online games, you must purchase more than the mainstream graphics card to meet the demand.

4, for some special user groups, such as design, 3D rendering, modeling professional users, you need to buy a dedicated workstation design graphics card, ordinary game graphics card is not suitable.

Finally, it is only mentioned that the graphics card is a must-have hardware for the computer. Any computer does not have a graphics card, and the display does not have a screen display. Therefore, a computer must contain at least one type of graphics card, including set display, nuclear display, independent display, and dual graphics. , like AMD Athlon series processor, FX bulldozer series processor and Intel Xeon E series processor, because the CPU is shielded and information point card, this part of the computer must be equipped with a discrete graphics card.
