Are you still blindly pursuing high computing power? 99% of mining machine manufacturers won’t tell you the secret

Miners all know that the performance of mining machines is directly linked to profits. There are more and more mining machine brands on the market, and the prices are getting more and more expensive. There are bound to be fakes among them. Faced with a wide range of mining machines, how to judge their overall performance? What are the requirements for ore dressing machines?

1: Are high-computing-power mining machines necessarily good?

In theory, the faster the mining speed, the greater the possibility of finding a valid hash value. The higher the probability of "block explosion", the more chances miners have to get high Bitcoin rewards. This has led many people to use computing power as the only criterion for choosing a mining machine.

As we all know, the computing power of a mining machine is determined by the performance of the chip. The iteration of the chip can greatly improve the computing power of the mining machine. However, after all, the chip is a high-tech equipment, and it is not so easy to update it. If the chip process is not effectively improved, there are only two ways to improve the computing power of the mining machine:

1.   Add hashboard.

2.   Increase the number of chips on the hashboard.

A 49T mining machine that has attracted much attention in the industry recently is a typical example of a machine that uses the number of chips to add up computing power. According to its official parameters, the mining machine has 6 computing boards and a total of 576 chips , which is equivalent to 96 chips on each computing board . Both the number of computing boards and the number of chips on a single computing board far exceed the average level of other mainstream mining machines on the market.

Professional mining machine engineers pointed out that if a single machine has too many hashboards, the most direct impact is that the mining machine will be too large. Such a machine is more difficult to repair, and is essentially no different from stacking multiple mining machines together. The size of the mining machine should be controlled within a certain range to optimize the overall performance.

It is even worse to forcibly increase the number of chips on the hashboard. When the mining machine is running, the chip will generate very high temperature. In order to dissipate heat in time, the chip is usually equipped with a heat sink. If there are too many chips on a single hashboard, the temperature will be too high, which will directly cause irreversible damage to the mining machine.

Conclusion: If the technological level of a certain mining machine does not improve significantly, but the computing power of the mining machine increases by leaps and bounds, the performance of the mining machine will be greatly reduced.

2. How to judge whether the price of the mining machine you purchased is cost-effective?

Usually, the price of mining machines on the market fluctuates according to the price of Bitcoin. But the specific price will be calculated in units of computing power. For example, when Bitcoin was 100,000, the futures price of mainstream brand mining machines on the market was about RMB 2,000/T . With the current price of 55,000, the price of mining machines is around RMB 1,200/T .

Recently, a company announced a mining machine with a computing power of 5120T, and the price of the whole machine is about RMB 7 million. Assuming that this money is used to buy a domestic 13.5T mining machine, you can buy 411 units, which is equivalent to 5548T computing power. It is reported that in addition to the high price, this machine has not been mass-produced. Currently, 100 units have been issued worldwide, and only 10 units are in China. In addition, the machine only supports hosting in Japan.

Therefore, some of the machines on the market that focus on ultra-high computing power are very eye-catching in the publicity, but the price is not particularly affordable. Sometimes it is more cost-effective to buy multiple mining machines with low computing power.

Conclusion: When judging whether the price of a mining machine is reasonable, you can refer to the market price per T computing power and make a horizontal comparison.

3: How to calculate the input-output ratio of mining machine operation?

In addition to studying how to get a mining machine from the official website as quickly as possible, a miner's daily routine should be to find cheaper electricity resources. After all, the biggest cost of mining is electricity. Therefore, we should pursue maximum benefits for every kilowatt-hour of electricity we invest.

All mining machines on the market have specifications, showing a series of parameters such as the product's overall computing power, wall power consumption, size, etc. However, there is one indicator that rarely appears in the parameter display of major mining machines, because it is like a "magic mirror" that directly reveals your power conversion rate, leaving some so-called "high computing power" "power hogs" nowhere to hide. It is - computing power per watt.

Simply put, this data means how much profit your mining machine can bring you for every kilowatt-hour of electricity consumed. The formula is G / W .

For example, a mainstream mining machine has a computing power of 13.5T and a power consumption of 1350W , and the computing power per watt is calculated to be 10.24G / W . Another brand of mining machine with a computing power of 12T seems to be not much worse than the former in terms of computing power, but because the power consumption reaches 2100W , the computing power per watt is only 5.85G/W , which is only half of the former.

Conclusion: Calculating the computing power per watt can help you see how much profit you get for every kilowatt-hour of electricity you invest, and prevent you from being misled by some parameters.
