Unit price of computing power

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. Recently, the price of bitcoin is relatively low, about 60000. The latest quotation of computing power on 58coin is about 0.0139btc, about 839 yuan / T. the computing power of an S9 mining machine is 13.5T, and the price is about 11000 yuan.

3. Personally, I think their computing power contract is very cost-effective and worth buying.

4. When the price of currency rises, the calculation power will rise, because the income of digging currency increases, so if you have the investment intention, the earlier you buy the calculation power, the more cost-effective it will be.

5. It's troublesome for you to calculate in several steps, and you need to use your force adjustment coefficient
1. Actual power factor = total active energy / sqrt (total reactive energy square + total active energy Square)
2. Through the actual power factor and force regulation coefficient standard, look up the table to get the adjustment proportion, which can be found in the network force regulation comparison table
3. Step 3: force regulation electricity charge = (basic electricity charge + electricity charge) × Adjustment ratio

you also need to provide the power adjustment coefficient and electricity tariff (customer price)

6. The key is that kind of calculator is more convenient. The speed of mobile phone is not as fast as calculator
the calculator on Google play calculates an integral. If it's a little more complicated, it will take about 4S< Moreover, the calculator is usually used by people with special needs.

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

8. 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
