Computer price

1. At the beginning of 2017, the price of a 14.5t S9 mining machine was as high as 20000 yuan. Take the current market situation, the cost of investment and mining is very low. Moreover, according to the current issue price of HRT, the cost of the same computing power is only about one tenth, which is about more than 2000 yuan.

2.

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>

ant mining machine S7 specification parameters:

1. rated calculation force: 4.86 Th / S ± 5%

2. wall power consumption: 1210 watts (bit mainland apw3-1600 watt power supply, 93% AC / DC efficiency, 25 ℃ ambient temperature)

3. power efficiency: 0.25 Joule / GH (wall, 93% AC / DC efficiency, 25 ℃) ° C)

4. rated voltage: 12V ± 5%, which should not be lower than 12.0V

5. number of single power board chips: 162x bm1385

6. overall dimension: 301 mm (L) * 123 mm (W) * 155 mm (H)

7. cooling: 2 × 12038 fan

8. working temperature: 0 ℃ to 40 ℃

9. network connection: Ethernet

3. Ant z9nini official website to the news is only for sale overseas version, from the pre-sale to now a few days, I have received a lot of customer orders! Because there is no prototype now, we can only analyze its cost performance from data and parameters! The official calculation power of ant z9mini is tentatively 10K / s, but the official announcement is that the calculation power of ant z9mini will be higher when it is really on the market. If the current 10K / s calculation power is used to dig the zero coin of Zec, the advantage is very obvious! At present, the 8K graphics card miner on the market has a unit price of 15800. The computing power of the price is only 2K, and the power consumption is about 1100 watts. The official power consumption of ant z9mini is 300 watts

4. The difference between mining by Sifang computing power users and mining by mining machines purchased by indivials is as follows:
①. Early stage investment: Sifang computing power provides, which saves users this link. Indivial: purchase of mining machine, selection of mining machine model, preparation of power facilities, etc
2. Field equipment: provided by Sifang computing power, users can save this link. Indivial: rental site, mining machine support rack, noise elimination equipment, etc
3. Software assembly: provided by Sifang computing power, users do not need to master professional knowledge. Indivial: learn professional software assembly knowledge or hire a special person to operate
4. Maintenance: Sifang computing professional technical team, all-weather supervision and maintenance. Indivial: employ professionals to supervise and maintain all day long< (5) electricity and electricity charges: professional large chain mines and users do not need to pay electricity charges. Indivial: the power facilities in the residential area are unstable, the price is high, and the cost-benefit of mining is unbalanced< (6) risk taking: users obtain BTC net assets. Indivial: the equipment investment in the early stage is huge, which is easy to form heavy asset operation, and the income and investment in the later stage are likely to be unequal.

5. At present, the total network computing power of lightcoin is about 400g. It is impossible for any miner to achieve this calculation power. At present, the calculation power of the world's best lightcoin miner is less than 1G. It is estimated that such a high computational power is sky high

when Leyte coin was born, its founder claimed that Leyte coin was not suitable for AISC. Now, Leyte coin has fallen sharply, which has nothing to do with mining machinery manufacturers

I guess it's bitcoin miner. Miner with 400g computing power is very common. The mainstream Avalon 3 single-mode group 290g on the market, the price is only about 1800. The price of ant s3440g is 2550 yuan.

6. There are many kinds of mining machines in the market, and the currencies they dig are different. Bitcoin machines are the most. From Shenma m3 and ant S9 to many computing power machines, customers have more choices. The computing power is getting bigger and bigger, and the price of machines will rise correspondingly. There are many small currency machines coming out, so if you are just starting to contact this instry, You can choose a BTC digging machine with high cost performance, and buy one or two back as a reference. If you suggest, you can choose ant S9 or core T2T, with computing power of more than 10 t to 30 t, and the price is less than 1000 yuan

7. At present, bitcoin mining machine has 14T computing power of ant s9i, more than 4000, and another is ant T9 + 10.5t computing power, about 1500

8. This question is too vague and direct! The answer is definitely different! Even if the al cards are 3G or 2G, the network speed will not be the same, and the signal strength of China Telecom and China Unicom or China Mobile in the same place will not be the same, understand?

9. Which fat man doesn't have a heart that wants to thin down, and I feel that it's not good. I don't think so alone. People who are not fat won't understand the mood of fat man. I never give up, study and stick to it. Finally, I'm thin down. I can wear beautiful clothes, and I'm thin and cherish it!

10. Mining machine price is OK, because compared with many platforms, their price is already preferential, and some of the guarantees and technical support they provide are very good.
