Overview of the new ASIC from Bitmain: ANTMINER S15 and T15 – characteristics and profitability

The new ASIC Antminer S15 and T15 from Bitmain run on the latest 7-nanometer chips, are energy efficient and are compatible with the SHA256 algorithm ( mine Bitcoin and Bitcoin Cash).

New models Antminer S15 and T15 have two different modes :

• energy saving,
• high performance.

In the power saving mode, the S15 consumes only 850 watts , which makes it a good option for use in regions with expensive electricity. In the high-performance mode, the miner consumes 1596 W, but, surprisingly, an increase in the hashrate compensates for the additional power consumption, even if you need to pay 12 cents per kWh.

In fact, the only reasons you can use an ASIC miner in energy saving mode are:

• reduce heat and noise
• if you do not have the infrastructure to support such increased power consumption.

Prices ASIKi S15 and T15

According to the data on Bitmain’s official website, the cost of the devices is $ 1,475 for the Antminer S15 and $ 913 for the Antminer T15.

The start of the first batch of equipment deliveries from December 20 to December 31, 2018.

Antminer S15 Specifications

S15 is more like a flagship – at least by price and hashrate.

• Mining Algorithm – SHA256.
• Weight – 7 kilograms.
• Price – $ 1,475 for the first batch (December 20-31).
• Dimensions – 221 x 175.4 x 278.8 millimeters.
• The presence of energy saving mode – yes.
• The hash rate in performance mode is 28 TH / s.
• The energy saving hashrate is 17 TH / s.
• Power consumption mode performance – 1596 watts.
• Power consumption in power saving mode – 850 watts.
• The design of the fans is parallel.
• The production technology of chips – 7-nanometer.

Miner has two modes of operation. The first is aimed at maximizing the hashrate, the second – to save energy costs.

Antminer T15 Specifications

T15 is simpler. Performance and cost are lower, while the chips are still 7-nanometer.

• Mining Algorithm – SHA256.
• Weight – 6.6 kilograms.
• Price – $ 913 for the first batch (December 20-31).
• Dimensions – 205.15 x 175.4 x 278.8 millimeters.
• The presence of energy saving mode – yes.
• Performance hash rate is 23 TH / s.
• The energy saving hashrate is 20 TH / s.
• Power consumption mode performance – 1541 watts.
• Energy consumption in power saving mode – 1200 watts.
• The design of the fans is parallel.
• The production technology of chips – 7-nanometer.

Yield Antminer S15

Today, the income from the Antminer S15 is $ 50 per month if you pay 12 cents per kWh. (in high performance mode).

The cost of electricity per month is $ 140 , which means that those who have free electricity can receive income from $ 190 per month. Even with the cost of electricity $ 0.08 / kW / h, the income from the device is still $ 95 / month at current rates and the complexity of mining cryptocurrency.

The payback of the Antminer S15 in high performance and energy saving modes

Bitcoin miners usually pay off in about two years, and S15 is no exception to the rule. If the mining difficulty remains the same, we can expect the investment to return in about 10-14 months. But the complexity of production will undoubtedly increase, therefore, in fact, the payback should be about 20 months.

Now consider how much will increase the complexity of mining ? Since the S15 is based on new technologies, we expect the complexity to grow significantly. We know that large companies (especially Bitmain) own most of the Bitcoin network hashrate. We also know that their hangars use cheap electricity.

S15 replaces the older series – S9. This means that instead of 14 TH / s, Bitmain will start adding 30 TH / s to its farms. This is not so much, given the existing colossal Bitcoin network hashrate.

In fact, for a Chinese farm (with almost free electricity), the Innosilicon T2 turbo 32 (32TH / s) can be a better investment than the S15.

Payback Antminer S15 in high performance mode:

The payback of the Antminer S15 in energy saving mode:

The obtained figures allow to draw conclusions about the payback of the device. It is more logical to count on maximum performance. We divide the $ 1,475 price by the maximum profit of $ 4.58. We get 322 days or almost 11 months. The result is relevant with the stability of the network and the course.

Profitability and payback Antminer T15

On top performance, ASIC will deliver 23 TH / s and 1541 watts.

3.49 dollars of profit per day at the same value of the outlet. We estimate the energy saving mode with 20 TH / s and 1200 W of consumption.

$ 3.2 per day in Bitcoin. The result of mining Bitcoin Cash is a little behind – 3.15 dollars.

Payback Antminer T15 – 913 dollars prices are divided by 3.49 dollars profit. We get 261 days or almost 9 months.

Of course, the rental of premises as a result is not taken into account. This factor will have to be considered independently.

Conclusion

Should I buy an S15? The device definitely belongs to the field of industrial mining, and "home miners" should, apparently, look for other options, such as cloud mining .

It seems that Bitmain itself will become the main consumer of its own S15 asiki, although those of you who have cheap electricity can get their share of the cake.
