What is the difference between mine mining and computer mining?

Bitcoin mining machines are now almost all eye-catching, like ant mining machines, Avalon mining machines and Shenma mining machines. Many miners have one or more bitcoin mining machines in their hands. Why do mining needs? Bitcoin mining machine? What is the difference between a Bitcoin miner and a computer? What are the selection criteria for Bitcoin mining machines? Below, follow the RHY mine to show you the difference between Bitcoin mining and computer mining.

Why do Bitcoin mining require ASIC mining machines?

When designing bitcoin, Satoshi Satoshi originally hoped that people would use home computers to mine and use the computing power of the CPU to collide with the hash value to obtain bitcoin. In January 2009, the average computing power of the whole network was 5.899 megabytes (M), and the difficulty of the whole network was 1, with a total of 2,494 blocks, equivalent to 124,700 bitcoins. At the same time, mainstream CPU chips such as the Core 2 Duo E8400 have a computing power of 6.9Mhash/s. So at that time, computer enthusiasts could easily mine at home or in Internet cafes. However, because the CPU is designed to handle general-purpose complex instructions (CISC), the calculation speed of the SHA256 algorithm for mining is not ideal.

With the influx of miners, the computing power of ordinary chips has shown a weak trend. The development of Bitcoin mining machine chips has gone through four processes from CPU, GPU, FPGA to ASIC. In this process, the chip that provides the computing power has gradually shifted from the general type to the mining-specific type.

After sacrificing general-purpose computing power, ASIC's mining capabilities and efficiency have also improved. For specific algorithm requirements, ASICs have smaller size, lower power consumption, higher reliability, and lower unit cost than mass-produced integrated circuits.

Bitcoin mining is a repetitive calculation under a specific algorithm, so the application of ASIC solutions will greatly improve the performance of the chip.

Is there a difference between Bitcoin mining machines and computer mining?

The ASIC Bitcoin mining machine is a computer that specializes in mining procedures and cannot do anything other than mining. Can't play Super Mario, can't pick mushrooms, and can't use WeChat. The difference between the two is similar to the difference between the Formula 1 car and the ordinary family car. The F1 is faster, but it can't do anything except the game; the ordinary car can't match the speed of F1, but it is more widely used in daily life.

For example, the current Avalon 7nm series Avalon mining machine A921, using 104 A3206 7nm ASIC chip, the computing power reached 20TH / s, the price of the whole machine is about 258.9886 US dollars, power consumption 1700W. In contrast, the current computer flagship graphics card NVIDIA Titan RTX single card price of 2893.5832 US dollars, power consumption of more than 280W, but the mining power will not exceed 60MH / s, and the Avalon mining machine A920 computing power difference of hundreds of thousands Times.

Pick the standard for bitcoin mining machines?

Calculation power

For example, the current network computing power is 43.75 EH / s, the entire network difficulty 6.07T, 24 hours output 1800 bitcoin. Then the 20T computing machine theoretically produces about 0.000827 bitcoins per day, about $3.1469.

2. Power;

Power represents the power consumption rate of the Bitcoin miner. A 1000W mining machine consumes 24 degrees in 24 hours.

3. Cost.

In terms of electricity consumption, the average price of the current electricity market is 0.05064 US dollars / kWh. A mining machine that consumes 24 degrees per day has a power cost of $1.2154. On the network side, the Bitcoin mining machine has low requirements on the network, and the 1M bandwidth can bring 150 mining machines, and the cost is almost negligible.

4. Return to this cycle.

Back to the cycle = mining machine price / (daily income - electricity fee), the return cycle is only the theoretical calculation of the number of days, the bitcoin market is changing every day, the difficulty of computing is also increasing, coupled with the mining pool and trading Therefore, it is difficult to try to calculate the exact return time.

However, it should be noted that when buying a Bitcoin mining machine, you should not only focus on high computing power and pursue the limit. The ASIC bitcoin mining machine is composed of dozens or even hundreds of ASIC chips, and the computing power can be increased without an upper limit, but the calculation is high. Force also means high power consumption and power consumption will increase.

Moreover, the current ASIC chip process of major mining machine manufacturers has a small gap. Excessive computing power means that the number of ASIC chips in a single mining machine is too large, and it is easy to overheat during operation. If the mine ventilation environment is not good, the mining machine may malfunction. greatly increase. Therefore, when selecting a mining machine, you must choose the Bitcoin mining machine that suits you according to your own situation (hosting environment, power resources, etc.). In addition, the mine is also an important option, the mine environment and electricity prices are closely related to the miners' mining revenue.

Therefore, many miners now choose overseas mines for mining layout, because overseas mines are cheaper. According to the large overseas mine, RHY Mine, its overseas mines in the Middle East have electricity rates as low as 0.02749 US dollars per kWh. The power supply is very stable and there is professional operation and maintenance. Miners can choose mining power and mining equipment such as mining machine rental and mining machine hosting. The majority of miners friends, today the bitcoin price is $ 7,317, you are ready to mine.
