Video card (graphics card) full name display interface card, also known as display adapter, is the most basic configuration of computer, one of the most important accessories. As an important part of the computer host, the graphics card is the equipment of digital to analog signal conversion, and it undertakes the task of output display graphics

the graphics card is connected to the main board of the computer, which converts the digital signal of the computer into an analog signal for the display. At the same time, the graphics card still has the ability of image processing, which can help the CPU work and improve the overall running speed. For those engaged in professional graphic design, graphics card is very important. Civil and military graphics chip suppliers mainly include amd (ultra micro semiconctor) and NVIDIA (NVIDIA). Today's TOP500 computer, including graphics card computing core. In scientific computing, graphics card is called display accelerator

2. As the name suggests, the mine calculation card is a graphics card used for mining. More strictly speaking, it is a graphics card used for mining with high load for a long time. The graphics card used in mining usually works at full load 24 hours a day for several months. In this way, PCB and electronic components will accelerate aging, affecting the life of components. Not counting the rest time of the graphics card, even if we play the game for 8 hours a day, the life of the mine card is only one third of that of the normal graphics card. It can be said that the general life of the mine card is only a few months.

3. Overlord. It is the earliest currency. However, other currencies, including Ethereum, are on the same level. Although they can't shake the dominant position of bitcoin, they are also eroding its original share. Maybe Ethereum can surpass it at any time!

4. Computing power is a concept put forward by NVIDIA when it released CUDA (Compute Unified Device Architecture, a programming language for GPU, similar to C programming for CPU). Because the graphics card itself is a floating-point computing chip, it can be used as a computing card, so the graphics card has computing power. Different graphics cards have different computing power. In order to show the difference, NVIDIA put forward the corresponding version of computing power x.x on the procts of different periods. Computing power 1.0 appeared on early graphics cards, such as the original 8800 ultra and many 8000 Series cards, as well as Tesla C / D / s870s cards. Cuda1.0 was released corresponding to these graphics cards. Today, computing power 1.0 has been eliminated from the market. Then there was computing power 1.1, which appeared on many 9000 Series graphics cards. Computing power 1.2 appears together with GT200 Series graphics card, while computing power 1.3 is proposed when upgrading from GT200 to GT200 A / b revision. In the future, there will be computing power 2.0, 2.1, 3.0 and other versions. The latest released version is computing power 6.1, which is supported by the latest Pascal architecture graphics card. At the same time, CUDA version is also updated to cuda8.0

ordinary users do not need to care about the computing power of the graphics card, only GPU programmers care about this problem when they write CUDA programs to develop GPU computing. As long as you know the model of your computer's graphics card, you can find the corresponding computing power https://developer.nvidia.com/cuda-gpus .

5. GPU is the "brain" of the display card, which determines the grade and most of the performance of the card. It is also the basis for the difference between 2D display card and 3D display card. 2D display chips mainly rely on the processing power of CPU when processing 3D images and special effects, which is called "soft acceleration". 3D display chip is the so-called "hardware acceleration" function, which integrates 3D image and special effect processing functions into the display chip. The display chip is usually the largest chip (with the most pins) on the display card. Now most of the graphics cards on the market use NVIDIA and ATI graphics processing chips< When NVIDIA released geforce 256 graphics processing chip in 1999, it first proposed the concept of GPU. GPU makes the graphics card less dependent on CPU, and does part of the original CPU work, especially in 3D graphics processing. The core technologies of GPU include hardware T & L, cubic environment material mapping and vertex blending, texture compression and bump mapping, al texture four pixel 256 bit rendering engine, etc
in short, GPU is a display chip that can support T & L (transform and lighting, polygon conversion and light processing) in hardware, because T & L is an important part of 3D rendering, which is used to calculate the 3D position of polygons and process dynamic light effects, also known as "geometric processing". A good T & L unit can provide detailed 3D objects and advanced light effects; However, in most PCs, most of the T & L operations are handled by the CPU (that is, the so-called software T & L). Because the CPU has many tasks, in addition to T & L, it also does non 3D graphics processing work such as memory management and input response. Therefore, in the actual operation, the performance will be greatly reced, and the graphics card often waits for CPU data, Its computing speed is far behind the requirements of today's complex 3D games. Even if the working frequency of CPU exceeds 1GHz or higher, it will not help much. Because this is a problem caused by the design of PC itself, it has nothing to do with the speed of CPU.

The main manufacturers of graphics chips are NVIDIA and AMD

Second, the chip model meaning of the graphics card

the chip model meaning of the N card: the model of the N card is composed of prefix + number

prefixes start with GTX, GTS, GT and GS respectively. The digital model behind it is the higher the performance, the stronger! At present, the most common N cards are GT and GTX. GT positioning entry level, GTX positioning middle level or above

the meaning of the chip model of a card: the model of a card is complicated. For example, the model of the latest Polaris architecture graphics card is RX + XXX, which starts with RX and is currently Polaris architecture graphics card. The higher the digital model, the stronger the performance

for example, rx580 & gt; RX570> RX560> Rx550 et al

for the performance of graphics card, please refer to the ladder diagram of graphics card performance:

7. It is the most important part of the graphics card, and also the GPU.
its function is to convert the digital signal of the computer into the analog signal that can be recognized by the display, and to calculate and process the image data

Display chip performance comparison

at present, there are professional websites or institutions that will update the so-called graphics card performance ladder map from time to time

network search year + graphics card performance ladder map

to find the relevant display chip performance ranking

9. Nvida used to be OK, but I heard that there is a problem now. Let's use via!

10. The display chip is the core chip of the graphics card. Its performance directly determines the performance of the graphics card. Its main task is to process the video information input by the system and construct and render it. The performance of the main display chip directly determines the performance of the display card. Different display chips, whether from the internal structure or its performance, there are differences, and their prices are also very different. The position of display chip in the graphics card is equivalent to the position of CPU in the computer, and it is the core of the whole graphics card. Because of the complexity of display chips, only NVIDIA, ATI, SIS, 3dlabs and other companies design and manufacture display chips. Home entertainment graphics cards all use single-chip display chips, while some professional workstation graphics cards use multiple display chips.
