7850 computing power

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. Don't think about mining. When you install the miner, the price may drop. As a whole, the electricity bill for one day is not enough. Mining machine, then at least 6 cards to have effect, the previous hd7850 speed is difficult to get a bitcoin a month!

3. It's too difficult for you to enter this field now. I'm afraid that even if you start the machine 24 hours, you can't find one in a month, and the electricity consumption will be astronomical.

5. 7850 has at least 320. 1000 yuan a piece. 290x more than 4000. That's 900.. So. You can calculate it yourself.. Of course, 7850 you can't buy.....

6. It's quite safe. Its income cycle is relatively short, and the amount of investment is not very large. The investment income is quite high

7. The so-called mining refers to a method of obtaining virtual currency (such as bitcoin, Shanzhai coin, etc.) through high-speed computing by computer or mining machine. For mining, the graphics card is the core, and the rest are auxiliary accessories. Considering that everyone uses different platforms, the mining cost considered here only includes the price of the graphics card and the electricity charge
in theory, no matter what graphics card is used, it is called mining with graphics card, but in the early days, it focused on the high end of a card, because it has a large number of stream processors and relatively strong computing power. The prices of hd7850, hd7870, rx480 and rx580 are unreasonably high. In 2017, Jingying's hd7850 was over 1000
later, n card came out of gtx1060. After gtx1070, most people began to dig with these graphics cards. And now, many people, no matter what graphics card, as long as it is Samsung memory, are used to dig. Gtx750, gtx750ti, these low-end graphics cards have attracted the attention of miners
therefore, HD4830 can also be used for mining. It is only because of the low computing power that it may not be able to earn back the electricity charges. It is recommended not to invest in it. Mining is risky and investment needs to be cautious.
