For investors who have mined, they all know that mining can be done with either a graphics card or a CPU. The specific tool and equipment used for mining depends on the mining efficiency and revenue, and the choice is different for different currencies. . Some currencies do not require a CPU but require a graphics card because the performance of the graphics card matches the currency, and when setting rules, the graphics card is used as a mining tool for the currency. Back in 2010, people could mine Bitcoin using their Intel Pentium CPUs and generate over 100 Bitcoins. But this is no longer possible, and this is true for almost all altcoins. Many investors still don’t understand why mining requires a graphics card instead of a CPU? Let the editor of the currency circle take you through it.

 Why don’t you use a CPU for mining but a graphics card?

Some currencies do not require a CPU but require a graphics card because the performance of the graphics card matches the currency, and when setting rules, the graphics card is used as a mining tool for the currency. The efficiency of mining has a great relationship with the configuration of mining tools, currency mechanisms, and rules.

Taking graphics card mining as an example, mining efficiency is related to the number of graphics cards, graphics card configuration parameters, and mining rules. If we evaluate graphics card mining from the perspective of efficiency, if the currency is limited to mining with graphics cards, compared with other mining methods, For example, hard drives, CPUs, mining machines, etc., the graphics card must have high mining efficiency.

But if we compare similar mining cards, whoever contributes more computing power will be more efficient. In addition, mining calculates the hash value by contributing computing power. The calculation method is similar, but it is not a repetitive calculation, and the results calculated every time are different.

 Introduction to the differences between CPU mining and graphics card mining

The difference between CPU mining and graphics card mining lies in the computing efficiency. The efficiency of CPU mining is not as high as that of graphics card mining. Compared with the complex calculations of the CPU, the GPU used by the graphics card performs general calculations. Therefore, hundreds or thousands of stream processors can be stacked. Each stream processor is like a small CPU. Although its ability to run complex programs is far less powerful than that of a CPU, it cannot support many stream processors, so the actual performance In particular, single-precision floating point performance is much stronger than that of the CPU.

Mining generally refers to the process of producing cryptocurrency using mining machines. Specifically, it is the process of participating in network accounting through computer CPU (memory), GPU (graphics card) or professional mining machine, and forming a proof of work (POW) based on accounting, thereby obtaining corresponding block rewards.

CPU mining is a type of cryptocurrency mining that uses CPU cores to verify transaction blocks, check blockchain transactions, and solve puzzles. It also creates new coins.

Graphics card mining: refers to the problem-solving process of using a computer motherboard to mine Bitcoin. Graphics card mining is to first make a formula with many answers. Users use their personal computers to download decoders and run specific algorithms to decode them. After communicating with the remote server, the corresponding Bitcoins can be obtained.

The above content is the detailed explanation of the editor of the currency circle on why mining does not require a CPU but a graphics card. Regardless, even today some cryptocurrencies are still focused on CPU mining. One such popular coin is Monero (XMR, RandomX algorithm), which is the largest and easiest coin to mine by CPU. Monero mining on AMD
It's profitable on Ryzen CPUs and some Intel processors. When it comes to mining, particularly cheap low-end CPUs are no longer profitable. But at least Ryzen
The CPU will pay off, but with the current network difficulties, it will still take more than a year to get ROI.
