What is a graphics card mining machine (GPU)? What is the difference between GPU and CPU?
GPU Mining Do you still remember the programmer who exchanged 10,000 Bitcoins for pizza? He was the first person to use GPU mining. As more people mined, ordinary CPUs did not have enough computing power, so this Programmers began to use graphics cards and GPUs for mining, which led to a global shortage of graphics cards, and this situation was repeated again in the Ethereum mining process.

Mining machine mining
As the computing power required for mining continues to rise, GPUs have also reached the upper limit of computing power. In order to break through this limitation, some people have invented professional equipment specifically for mining. Although these devices are all computers, they can't do anything except mine Bitcoins and run hash operations. We call them "mining machines." Bitcoin mining machines can only perform calculations based on Bitcoin algorithms.

Litecoin mining machines can only perform calculations on the Litecoin algorithm and cannot be used interchangeably with each other. It’s not that it’s technically impossible, but that mining machines are essentially a computing competition, a process that constantly breaks through the limits of computing. All conditions need to be reached to the extreme to win in the competition. If both are taken into account, the efficiency of operation will only be reduced, and the computing power will not be able to keep up with that of specialized mining machines, thus being eliminated by the market.

Because the chips of mining machines require very strong R&D technical strength, they need to compete with the rising computing power of the world and integrate with technology. In the early days of the industry, there were many examples of mining machines being eliminated from the market as soon as they were launched, or even being eliminated during the production process, resulting in heavy losses for both entrepreneurs and investors. Therefore, when choosing a mining machine, you also need to choose a strong brand and team.

Since the competition among mining machines is so fierce, how should you choose a mining machine if you want to mine? In theory, of course, it is best to choose the latest model. The latest mining machines consume less power and have very high computing power. So how to select a mineral concentrator?

1. Looking at computing power means looking at a computer’s ability to perform calculations, that is, how many hash operations the machine can perform per second. The current computing power of mainstream Bitcoin mining machines is 14T, which means 1410^13 power hash collisions per second.

2. Looking at power consumption is an indicator of the power consumed by this mining machine when it is running. Power consumption will have a huge relationship with mining costs. Generally, a mining machine will run 24 hours a day to mine, so the power consumption sometimes seems to be a small difference. In fact, the difference in cost over a year is still relatively large. of.

3. Look at historical reputation. There are currently two most well-known Bitcoin mining machine manufacturers in the world, Bitmain’s Ant Mining Machine and Zhang Nangeng’s Avalon Mining Machine. The latter is also the first in the world
The inventor of ASIC chip mining machine. ASIC refers to an integrated circuit designed and manufactured in response to specific user requirements and the needs of specific electronic systems. Nowadays, companies that make mining machines basically started by making chips. Mining machines are composed of chips, cooling fans, batteries and other components. The core component that determines whether the mining machine can dig out more coins is the chip. Another little knowledge here is that digital assets with the same algorithm can be mined with the same mining machine. For example, a Bitcoin (BTC) mining machine can also mine Bitcoin Cash (BCC), and an Ethereum (ETH) mining machine can also mine Ethereum Classic (ETC).

What is the difference between GPU and CPU? To understand the difference between GPU and CPU, first we know what GPU and CPU are:

CPU mining When Satoshi Nakamoto invented Bitcoin, he hoped that everyone could participate, and did not want to have dedicated mining machines. You should have heard stories about people using laptops to mine at home or in the office in the early days. At that time, CPU mining was still used. However, the era of CPU mining has long passed, and now Bitcoin mining is the era of ASIC mining and large-scale cluster mining.

CPU：Central
ProcessingUnit, central processing unit, is a very large-scale integrated circuit and is the computing core and control core of a computer. Its function is mainly to interpret computer instructions and process data in computer software.

GPU: Graphics Processing Unit, image processor, is a microprocessor specialized in image computing on personal computers, workstations, game consoles and some mobile devices.

In order to enhance the ability to display images, the graphics card eliminates many transistors that have nothing to do with the display function. Therefore, the graphics card can only display the image, but it is much faster than the CPU in the task of displaying the image. The tasks that need to be performed for mining are exactly the same as those of the graphics card. almost.
