First of all, Bitcoin was originally mined by cpu, but the number of cpu cores is small, and the mining algorithm is simple but complex, which does not need strong cores and requires a large number of small cores. Therefore, a method of mining with graphics cards is developed. Now, later, a professional mining machine was developed, with only calculation function and no display function, with super calculation ability and high efficiency. At present, no one uses graphics cards to dig bitcoin. They are all professional mining machines.

Graphics cards are basically digging Ethereum. However, at present, there are also Ethereum mining machines listed one after another, and the computing power of the whole network has soared, and Ethereum 2.0 has also been put on the agenda. I believe that the future graphics cards will be reduced in price.

The internal structure of CPU and GPU is very different. CPU uses a small number of more powerful ALUs (arithmetic units), while GPU uses a large number of ALUs with simpler structure. Therefore, the performance characteristics of CPU and GPU are completely different: CPU focuses on complex logic control and general serial operation, while GPU tends to handle large-scale concurrent calculation (graphics and image processing, which also belongs to this kind of operation), so CPU and GPU belong to different departments.

Digging bitcoin does not require a high single computing power, and the number of cores is exactly the number of GPU cores, so a graphics card is needed.

Little friend, have you ever heard of GPU?

Shouldn't this kind of question go to Baidu?
