The computing power required for mining is usually completed by hashing and decryption algorithms. This algorithm has a feature of low complexity, but extremely high strength, which is exactly what GPU is good at.
Both CPU and GPU can calculate, but they are good at different aspects. There are few CPU cores, but the architecture is complex, the logic control unit is complex, and it is better at complex operations; GPU has many cores, but its architecture is relatively simple, which is very suitable for Qualcomm and high-density computing.
Roughly speaking, CPU is equivalent to a college student who can do advanced mathematics, while GPU is like a hundred primary school students who can only do four operations. It is definitely better for college students to solve Olympic math problems, but to calculate the addition, subtraction, multiplication and division of 1000, a college student can't be faster than a hundred primary school students in any case-primary school students can do parallel calculations together, but how many problems can college students calculate at a time?
Mining algorithms such as hashing and encryption are like massive problems of addition, subtraction, multiplication and division. They are not difficult, but they need to be calculated repeatedly, which coincides with the advantages of graphics cards.
In this round of digital currency's skyrocketing market, the price of graphics cards has been greatly pushed up, and the biggest driver is actually not Bitcoin, which everyone is most familiar with, but Ethereum.
Today, the computing power of participating in bitcoin mining is already very large, and it is impossible to obtain enough distribution weight in the mine pool by relying on the graphics card. Now, if you want to get a share in bitcoin mining, you need a special mining machine.
Unlike Ethereum, it can still be calculated by the graphics card at present, and its algorithm Ethash has very high requirements for RAM, and the calculated results will be directly stored in RAM. At present, the bottom line of RAM capacity is 4G. So now graphics cards with certain computing power and large memory are more popular. In order to achieve stronger mining performance, many miners will overclock the memory. It can be seen that at present, the graphics card is indeed one of the most suitable tools for digging Ethereum, and the CPU is not good at it.
