Mining calculation rate of Qicaihong 1660s graphics card

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}

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

bitcoin was obtained by CPU in the early days. With the continuous development of GPU speed and the emerging advantages of GPU general computing, miners graally began to use GPU instead of CPU for mining. Bitcoin mining uses SHA-256 hash operation, which will carry out a large number of 32-bit integer cyclic right shift operation. Interestingly, this algorithm operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate in NVIDIA GPU. This one alone brings an additional 1.7 times of computing efficiency advantage for AMD GPU. With this advantage, amd GPU is favored by the majority of miners

advise the landlord not to dig up if the budget is not too much!!! This money is not earned if you want to

the difficulty of bitcoin is increasing. Mining with graphics card is a race against time. The main reason is that the difficulty of mining bitcoin is graally increasing (the reason of bitcoin algorithm design). If a set of platforms can get 1 bitcoin per day according to the current difficulty, then in one month, the platforms with the same computing power will only get 0.8 bitcoins, even the top graphics cards will get 18.2 days (which can't be shut down), and the lowest second-hand hd7750 will need more than 400 (it will take 214 days to get one). Just look at this figure (this is the data in May this year, Now it's more than 18 days)

people can earn money by buying several mining machines (mining machines with dozens of top graphics cards piled together)

I hope I can help you

3. If it doesn't work, mining needs to be operated at full load. A single card should basically be rated at about 200W, and three cards should be at least 600W. In addition to the processor and other power consumption, the connection is to use the power supply rated at 700W.

Gtx1660s is much worse than rtx2060 in performance and parameters

At present, Qicaihong has six versions of gtx1660s graphics card, as shown in the figure below, with the core code tu116. The core frequency of the six versions is different, and other parameters are basically the same. Master Lu runs about 16W

6. Now the third generation of RTX has been fully launched. In terms of performance, gtx1660s must be too poor
however, the mainstream games on the market can run smoothly
computers are paid for every cent, but do you report your configuration every time you play games?

7. Try to replace the old driver, but it's not enough. There's something wrong with the graphics card

8. It's better

950 is not 970, 980. The gap is still small. After all, the last generation of graphics card

9. It's impossible without proct instructions. It's the same as the certificate of conformity. However, there is no requirement for the specific form. It can be in this book or in other forms. Please check it carefully

10. If you want to see the size of video memory, use gpu-z instead of using windows to blindly estimate the data.
