Ant S7 computing power

1.

It is reported that the performance of bm1385 chip is more than twice that of bm1384

The power supply scheme of S7 is similar to that of S5. The S5 + mode of dense chip arrangement is adopted, which makes the arrangement structure more compact. Under the same space, 60 chips are placed in S5 and 162 chips are placed in S7

The price of S7 is 1823 US dollars, equivalent to 11650 RMB yuan, and the delivery time is from September 21 to September 30. At the same time, the official announced the parameters of ant mining machine S7. The chip adopts bm1385, a 28nm fully customized chip independently developed by bitcontinental, with a computing power of 4.86t and a power consumption of 1201w. Ant miner S7 is the best miner with the best power consumption ratio so far, and the power per T is about 250W

official website is not open for sale at the moment. Users of early adopters can place their orders in overseas official website. The delivery address is 17% of the Chinese mainland tax and the purchase price is 13630 yuan. p>

According to the current difficulty, we can dig about 0.01584 bitcoins a day. Of course, the final result of each mine is not the same, but it will be very close

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

4. You are talking about two mobile phones. The price of the new one is very expensive, about 0.01 a day

5. The style is generous

6. It's the same as bitcoin. The algorithms of both are the same.

7. Because of different brands, the design concepts of procts are different, and each has its own advantages
it is recommended to choose the right mobile phone according to the needs and preferences. Due to the large number of mobile phone models and different application groups, you can visit Samsung website to view the popular flagship models and the latest procts.
