Mining parameters

1.

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

2. The core can exceed 1g, and the video memory is 5200mhz. If you worry about the heat dissipation, the core is 930mhz, and the video memory is 5000mhz (without external heat dissipation). If you install water cooling or better heat dissipation, you can exceed more, or you can exchange fire and overclocking
3. Stop digging.. It's too bad to mine now
4. N6 Series graphics card mining? Do you think too much? It's not known whether 10 years is enough for one year's electricity bill.

    7. The future? Now mining has mainly used special mining machine, and in the future will not mix with ordinary graphics card to make graphics card prices out of stock.
