What is the use of a computer discrete graphics card, what is the use of a discrete computer graphic

Clearer development, faster processing of high-resolution games, and smoother work.

1. The main function of the graphics card is to process the instructions and data provided by the CPU into text or images that can be accepted by the display and display them, so as to provide a basis for users to continue running or terminate the program.

2. In layman's terms, the graphics card plays an irreplaceable role when you play large-scale 3D games, and the more high-end the graphics card, the better the effect of playing 3D.

3. Independent graphics card refers to the display chip, video memory and related circuits are made separately on a circuit board, which is self-contained and exists as an independent board, which needs to occupy the expansion slot of the motherboard.

4. The main advantage of a discrete graphics card is that it has its own independent video memory and will not occupy system memory.

5. Nowadays, most gaming computers use discrete graphics cards. Moreover, the independent graphics card can be composed of multiple graphics cards inside the computer, and has powerful image processing capabilities.

6. The independent graphics card is for the integrated graphics card, the integrated graphics card is integrated on the motherboard, there is a special display chip on the motherboard, there is no independent display memory, or the display memory is very small (generally no more than 16M).

7. When working, the integrated graphics card occupies the memory of the computer and is used as display memory, which is a little inadequate in playing 3D games and processing 3D images, which will reduce the running speed of the computer. The advantage of integrated graphics is that it is cheaper.

There are two types of graphics cards currently used on computers: discrete graphics and integrated graphics, which users can choose to use.

1. A discrete graphics card refers to the display chip, video memory and its related circuits are made separately on a circuit board, which is self-contained and exists as an independent board, which needs to occupy the expansion slot (ISA, PCI, AGP or PCI-E) of the motherboard. The independent graphics card is installed separately with video memory, which generally does not occupy system memory, and is much more advanced in technology than the integrated graphics card, which can get better display effects and performance than the integrated graphics card, and is easy to upgrade the hardware of the graphics card. The disadvantage is that the power consumption of the system is increased, and the heat generation is also larger, which requires additional funds to buy a graphics card.

Second, the integrated graphics card is to make the graphics chip, video memory and its related circuits on the motherboard, and the motherboard is integrated, and the system memory needs to be used as the video memory, and its usage is automatically adjusted by the system. The advantage is that the system power consumption is reduced, and there is no need to spend extra money on a graphics card. The display effect and performance of the integrated graphics card are poor, and the hardware upgrade of the graphics card cannot be carried out.

The processing of the integrated graphics card is achieved by the operation of the CPU, and the video memory also occupies memory, which will greatly reduce the computing speed, and the integrated graphics card can only complete the general 2D, and some simple 3D work. When playing 3D games, a lot of complex calculations are required, one is acceptable, two or more integrated graphics cards are not enough, in exchange for smooth game speed, only to sacrifice the picture quality, severe blue screen or crash. 。

A dGPU is a type of graphics card.

Graphics cards are divided into integrated graphics cards and independent graphics cards.

A discrete graphics card is a discrete graphics card, and an integrated graphics card is an integrated graphics card.

Integrated graphics cards often occupy CPU resources, if the CPU itself performance is not strong, it will affect the entire operation of the system and then process complex image information, it is inadequate, independent graphics cards have independent chips that can process images, compared with integrated graphics cards, the ability is stronger, and the impact on the system is smaller.

Laptop graphics card means that the notebook is configured with a separate graphics card and video memory, and the graphics card is not integrated into the CPU.

Hello, notebook independent graphics card means that the graphics card of the notebook is an independent graphics card, and the independent graphics card is a display chip and related devices made into a board independent of the computer motherboard, becoming a professional image processing hardware device. Its performance is far superior to that of onboard graphics cards, and it can be used not only for general work, but also for perfect 2D effects and strong 3D levels.

Independent graphics card is also known as independent graphics card, graphics card is an independent individual, can be directly installed in the computer, for laptops, independent graphics card is also a separate individual, with independent graphics card chip.

The meaning of the notebook independent graphics card is that the graphics card of the hardware part of your notebook lock configuration is a discrete graphics card, which corresponds to the integrated graphics card. So, what's the difference between a discrete graphics card and an integrated graphics card for a notebook? Let me briefly summarize it below.

First of all, the discrete graphics card of the notebook, the huge advantage is in terms of performance, the discrete graphics card can improve the image quality and smoothness of the game, and can also make the graphics processing software faster and smoother, on the other hand, the discrete graphics card is relatively more high-grade.

However, the independent graphics card configured with the laptop also has certain disadvantages compared with the integrated graphics card, first of all, in terms of **, the cost of the independent graphics card is relatively high, often more than twice as high as the integrated graphics card, on the other hand, the independent graphics card power supply heat dissipation and compatibility requirements are relatively high, the independent graphics card needs a power supply with enough wattage, and this power supply is more power-consuming, some independent graphics cards also need independent power supply, in terms of maintenance costs, The discrete graphics card of the notebook is naturally higher than the model of the integrated graphics card, and the most important thing for the notebook is to choose the discrete graphics card or the integrated graphics card, and the most important thing is to make a decision based on your actual needs and budget.

The recommended model is powered by an Intel 11th Gen Core i7-11800H processor, 16GB of RAM, a 512GB SSD, and an RTX 3060 discrete graphics card.

5. Thor Zero

One of the dark horses in the game market in the first half of the year is none other than Thor Zero. It is no exaggeration to say that this machine exceeded expectations in all aspects, so it quickly gained the approval of many Xifan users. The recommended model is powered by an Intel 11th Gen Core i7-11800H processor, 16GB RAM, a 512GB SSD, and RTX 3060 discrete graphics, as well as Wi-Fi 6 and Thunderbolt 4 support.

The advantage is that the picture rendered by the independent display can be output to the screen without loss, and the cost is that the high-power independent display always runs, and the battery life "blood collapses".

For gaming laptops with built-in independent graphics, when playing large-scale 3D games, all the images need to be rendered by the independent display, and the rendered data stream also needs to borrow the core display to output the picture to the screen of the notebook, this mode can also be called "hybrid mode".

Due to the addition of the "middleman who makes the difference", it will inevitably lead to energy loss and latency, which is reflected in the actual game experience is a decrease in frame rate. The correct way to deal with it is to keep the core display connected to the screen in low-load environments such as office and Internet access to save power. When running a game, find a way to bypass the electrical signal of the screen and communicate directly with the independent display, which is the "direct connection of the independent display" technology that many mid-to-high-end game laptops focus on today.

Comparison between direct connection and hybrid mode:

There is only one graphics card, and the hybrid mode is that there is an independent graphics card, and there is a graphics card in the CPU, called GPU, the graphics card in the CPU for office use is enough, and if you play games, the operating system will automatically convert to a separate graphics card to run.

In the hybrid output mode, the independent graphics card of the notebook completes the main image rendering work, and then the rendered image model is sent back along the PCIe channel, and handed over to the core graphics card attached to the processor for the final image model output work. The direct connection of the independent display card can be understood from the literal meaning, that is, the graphics card is the same as the desktop graphics card, working alone, not being transmitted back to the CPU, and the computer system cannot recognize the core display. <>
