Which ASIC miner is good for digging big change

1. I recommend eco and RCO, which are better than bitcoin. This is the simplest digital currency that can be found at present. It's easy to directly mention the currency exchange transaction to realize it.

2. The miner is composed of chips, cooling fans, batteries and other components. The "chip" is the core component, which determines whether the miner can dig out more digital currency more easily. mining machine chip manufacturers need to have a very strong R & D strength, need to race with the rising global computing power, test the ability to integrate with science and technology. Therefore, it is very important to select powerful brands and teams
at present, there are two most famous bitcoin miners in the world: ant miner of bitcoin mainland and Avalon miner of Zhang Nangeng. The latter is also the inventor of the first ASIC chip miner in the world
when choosing mining machines, we should first look at computing power, second look at power consumption, and third look at historical reputation
computing power is the ability of a machine to perform operations, that is, how many hash operations can this machine perform per second. At present, the computing power of mainstream bitcoin mining machines is 14T, that is, 14 * 10 ^ 13C hash collisions per second
power consumption is an indicator of power consumption when the mining machine is running, which is directly related to the cost of mining. Under normal circumstances, the mining machine will operate 24 hours a day, so even if the power consumption of different types of mining machine is very small, the power cost gap is very large
the historical reputation represents the stability of the miner's operation. You can know the overall user evaluation, after-sales service and whether the prepayment miner can deliver on time from different purchase channels
to say that the simplest way is to directly select the latest spot miner model. Because the latest mining machine power consumption will be relatively small, computing power is relatively high, input-output ratio is the most cost-effective
we need to remind you that the noise of the miner is relatively loud, which is also a tough injury of the miner.

4. GPU is the meaning of graph line processor, the original design intention is to do graphics computing. GPU chip is essentially a collection of many small CPUs for image processing. Of course, each CPU can also do general operations such as addition, subtraction, multiplication, division or non shift jump, so it can also be used for mining. When GPU is mining, it wastes less chip area and power consumption than CPU, so mining efficiency is higher than CPU
What about ASIC? It is a more optimized circuit than the CPU mentioned above. There is no specific definition, but there is a rule in the field of chip design: the more general computing platform, the less efficient it is to complete specific computing. ASIC is the most dedicated computing platform. If we understand this, we can come to such a basic conclusion: in the mining field, if we use the computing power proof mechanism, as long as the CPU can dig, ASIC can dig. No matter what algorithm is used, ASIC can dig. There is no reason that CPU can dig, but ASIC can't, So the biggest difference between GPU and ASIC is their specific computing power.

5. Wait; The Avalon ordered in October last year has not been received yet; Now we have to order three. Four months to get it.

6. Bitcoin mining has formed a huge instry in the world, and it is difficult to dig bitcoin again with ordinary computers. Therefore, it is better for building owners to buy professional bitcoin ASIC mining machines and join the mining pool for mining
bitcoin mining machine market has a high threshold and deep water depth. It is recommended to be cautious. Building owners can buy bitcoin mining machines on professional platforms such as 58btc. At present, the mainstream mining machines in the market are ant S9 and Avalon mining machines. It is said that the expected limit of S9 mining machine and silicon chip is 7 / 10nm, which can be g for a very long time and obtain high profits.

7. Nakamoto once said that the number of bitcoins is fixed at 21 million. Since the bitcoin was g out, the price has been high. However, with more and more miners, we all see the fat of blockchain mining. Mining is naturally more and more difficult, so it is very important to choose a good miner. At present, the mainstream miner is ASIC miner, graphics card miner, GPU miner, storage miner. Specifically, we need to find a professional mining platform to ask, such as jinhoe mining, professional mining platform, each miner model should have it, you can try to ask.

The main differences between 7Nm and 10nm are as follows:

1, gate length is different. The width of the gate formed on the CPU is also called the gate length. The 7Nm process can integrate more transistors into CPU and GPU, and make the processor have more functions and higher performance

2. Different power consumption. For 7Nm technology and 10nm technology, the volume of 7Nm will be smaller when the same number of transistors are plugged. The large volume of 10nm, because of the process problems, will lead to the larger capacitance of the original, the required voltage is higher than 7Nm, resulting in higher overall power consumption

performance:

the chip is composed of transistors. The smaller the process, the more transistors in the same area of the chip, and the stronger the natural performance. The performance of 7Nm is better than that of 10nm

take Huawei Qilin 980 as Qilin 970, where Qilin 980 is a chip with 7Nm process and Qilin 970 is a chip with 10nm process

first look at the number of transistors, Kirin 980 has 6.9 billion transistors, Kirin 970 has 5.5 billion transistors, an increase of about 25.5%. In terms of performance, it's not as simple as 25.5%, because it involves not only the number of transistors, but also the upgrade of CPU, GPU, NPU and other IP cores

in terms of specific values, for example, the running points of CPU, Qilin 980, GPU and NPU are about 50% higher, twice as high

extended data:

integrated circuits have two main advantages for discrete transistors: cost and performance. The low cost is e to the fact that the chip prints all the components as a unit through photolithography, rather than making only one transistor at a time. The high performance is e to the fast switching of components, which consumes less energy, because the components are small and close to each other. In 2006, the chip area ranged from a few square millimeters to 350 mm, with a million transistors per mm
