Graphics bar mining

1.

You can refer to the following, according to some commonly used graphics cards in the Internet bar market, sort out the price and calculation power of a related graphics card, as well as the expected return to the current period, It can be used as a reference:

{rrrrrrr}

power consumption: 243w
computing power: 22.4m
price of graphics card: 1999 yuan
quantity of eth g every 24 hours: 0.015
revenue generated every 24 hours: 24.48 yuan
expected payback time: 81.66 days

power consumption: 159w
computing power: 24.3m
price of graphics card: 1599 yuan Yuan
number of eth g every 24 hours: 0.017
revenue generated every 24 hours: 27.9 yuan
estimated payback time: 57.31 days

total power consumption: 171w
computing power: 24.4m
price: 1999 yuan
number of eth g every 24 hours: 0.017
revenue generated every 24 hours: 27.87 yuan
estimated payback time: 71.73 days

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

The so-called mine card is bitcoin mining graphics card. Because of the overload operation of the mine card, the life of the graphics card is shortened and the aging is serious

the bitcoin mining machine is the computer used to earn bitcoin. This kind of computer generally has professional mining chips, and works by installing a large number of graphics cards, which consumes a lot of power. One of the ways to get bitcoin is to download mining software and then run specific algorithm to communicate with remote server to get corresponding bitcoin

mining is actually a competition of performance and equipment. Some mining machines are made up of more graphics card arrays. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining

the discrimination method of mine card, Even the plastic plug is on it, so pay a little attention to it

The second is to look at the capacitance and other components on the graphics card. In essence, the graphics card is a combination of various chips and electronic components on the PCB board. In the process of overclocking and long-term use, the mine card will cause many components to turn yellow. If you carefully observe, the video memory chip will be black in yellow phenomenon, and then according to the time of the video card to judge, this will be more secure

3. There is also the mark of screw. Only a few mine cards are installed with screws. If the screw hole position of the second-hand card purchased by yourself is very new or even has no mark, you should pay attention to it

3. CPU can be used to mine, but the efficiency of CPU mining is not as high as graphics card. In order to make money, absentees have to calculate the input-output ratio. The input-output ratio of mining with graphics card is higher, so we graally start mining with graphics card. Now you should understand why mining with graphics card does not use CPU.

4. Mining is a way of virtual currency, it is the ruthless occupation of power and graphics resources. Of course, the fire of chicken eating games is also a reason for the sharp increase in the sales of graphics cards and memory moles
therefore, the relationship between supply and demand determines the price of goods. Now the graphics card, especially the high-end graphics card, is in short supply. That's why the price is high

5. Memory jammed, too high temperature, loss?

6. HD5870 graphics card
built in 1600 stream processors

pay attention to the number of stream processors in mining

and this graphics card is very affordable now

7. Mining is to dig bitcoin. Now the price of bitcoin has increased. If you dig bitcoin and sell it, you can make money for yourself.

8. Mining is to use the high computing power of graphics card to dig bitcoin
if you dare to buy a mining card, you must have faith and believe that you are lucky enough

9. This is very simple. You can compare CPUs to PhD students, who are very good at dealing with complex problems. The stream processors of graphics cards are high school students. However, there are only a few CPU cores (for example, 8 cores), and there are thousands of stream processors for a single graphics card.
mining is actually equivalent to pasting envelopes. If you think about it, eight PhD students paste quickly, Or more than a thousand high school students
mining is to use the parallel computing function of graphics card to solve simple but huge mathematical problems
