Antminer R4 is one of the latest innovations of miners for a cryptocurrency production created by Bitmain.
In this review, we will talk about its characteristics, profitability and payback, can we buy R4 in 2018, we will open its further prospects and cost.
Antminer R4 Characteristics
On the market of ready-made mining farms there are already more powerful representatives, such as Antminer S9 and Antminer D3 , but R4 is one of the best options from the ratio of price, profit and comfort from mining Bitcoin at home.
Anthemer R4 hashes up to 8.6 TH / s, making it the second and fastest after Antminer S9, R4 surpasses .
- 8.6TH / s hash rate (deviation ± 5%);
- Power consumption: 845 W + 9% (with Bitmain APW5 power supply)
- Energy efficiency: 0.1 J + 9%
- Noise level: 52 dB (at an ambient temperature of 35 ° C)
- number of chips: 126 x BM1387
- default frequency: 600 MHz
- Rated voltage: 11.60 ~ 13.00V
- Network connection: Ethernet
- Operating temperature: 0 ° C to 40 ° C
- case dimensions: 515 mm / 100 mm / 222 mm
The efficiency of R4 is equal to 0,098 J / GH due to the fact that it is built on the most powerful processor on the market. Here is a direct quote from the Bitmain website:
The Bitmain BM1387 chip is built using 16-nm FinFET technology from TSMC and provides a record 0.098 J / GH, is the world’s most efficient bitcombe chip in the consumer market.
Miner R4 consists of 126 such chips, which are manufactured using 16-nm process technology. BitFury became the first company to release 16-nm chips.
Antminer R4 uses the most modern power supply (PSU) to date. Bitmain recommends using the APW5 power supply.
The APW5 operates with a 220V and 110V output for 2600W and 1300W, respectively. APW5 is sold separately for about $ 240.
Noise at work
One of the most unique features of the Antminer R4 is that it was designed to provide the least possible sound with maximum hash frequency.
Antminer R4 replaces the traditional fan with a rotating blade system. A traditional fan was the biggest source of noise for other equipment mining industry.
The Antminer R4 fan is a split air conditioner, which reduces the noise of the standard miner by 50%, the sound level is 51 dB. Its fan speed is controlled automatically, ensuring that the noise is regulated.
The Antminer R4 uses the Xilinx ZYNQ-7000 system on a chip that combines the ARM Cortez-A9 multifunctional basic processing system.
It also uses Xininx 28 programmable logic, supports Gigabit Ethernet to ensure instantaneous block calculations.
Setting up Antminer R4
After installing Antminer R4, you’ll see that its interface is well designed with user interests in mind. It is very easy to use.
All that you need is to enter your bitcoin wallet address and the pool settings, after which the cryptocurrency mining will be automatically started. You can also set parameters such as fan speed or frequency.
Antminer R4 price
As they say, a good thing is expensive. With all the great features that come with the Antminer R4, its price is high. One Antminer R4 on the manufacturer’s website is worth $ 1000.
Profitability and payback of Antminer R4 in 2018
So, how the device was developed primarily for BTC mining, consider its profitability in 2018, the profitability of R4 at a set hashing frequency of 8.6 TH / s.
Your costs will be $ 1000 for Antminer R4 and $ 240 for the APW5 power supply. The miner consumes about 845 watts, so you should consider the cost of electricity.
The net income of Antminer R4 per day is: $ 8-10 per day, $ 360-400 per month, at the current Bitcoin exchange rate around $ 7000, you will need about 3-4 months to recoup the investment, the floating period depends on the complexity of the currency mining, and when accounting if the electricity will not cost more than 6 rubles per kilowatt.
Reviews about Antminer R4
Of course, risks need to be taken into account, and all factors do not remain constant, with Bitcoin’s changing world. This means that the Antminer R4 will eventually bring in profit, but only if the network hash level, bitcoins price and electricity costs remain unchanged.
Thus, you are definitely at risk, and this may not be worth your time, despite the many advantages that the miner provides compared to other equipment.
The production of bitcoins at home in 2018 has become almost impossible task, so it’s worth paying attention to less popular ones, but promising for investment cryptocurrencies.
