Graphics card or CPU

1. Now it is suggested not to mine bitcoin at will. After all, because of the problems in the country, the price of bitcoin in China is not good. Moreover, the computing rate of ordinary home computers can't keep up at all, and they may not be able to dig out a bitcoin for hundreds of hours in a row. During this period, the electricity and hardware consumption are not worth the loss.
2. It's very easy to judge whether the CPU is working,
disassemble the host computer, press the power on button, and then check whether the CPU fan is rotating
has this problem ever occurred on your computer before
does it crash after a period of work
if it is, the temperature of CPU is too high, and it will shut down automatically. You should help it cool down.

3. It's bitcoin. It can only use GPU, which is graphics card
4. Bitcoin was acquired by CPU in the early days, e to different working methods. CPU is mainly to do full-function operation, the number of core is small, and the operation ability is limited (GPU is a very large number of operation core for special operation). With the advantages of GPU general computing and the continuous development of GPU speed, miners graally began to use GPU instead of CPU for mining. Bitcoin mining uses SHA-256 hash operation, which will carry out a large number of 32-bit integer cyclic right shift operation. Interestingly, this algorithm operation can be implemented by a single hardware instruction in AMD GPU, while it needs three hardware instructions to simulate in NVIDIA GPU. This one alone brings an additional 1.7 times of computing efficiency advantage for AMD GPU. With this advantage, amd GPU is favored by the majority of miners. At present, it has left GPU computing. At present, miners have begun to widely use integrated circuit (ASIC) mining machine. Although this kind of mining machine can only be used to dig bitcoin, other currencies can not be used yet, but a single mining machine can reach the level of megabytes, especially loved by mine owners in Sichuan, Guizhou and other regions. Tens of thousands of professional mining machines are in full swing, and retail investors are unlikely to get bitcoin in the face of such powerful computing power.
5. Theoretically, both CPU and GPU operations can be mined
in the early days of the advent of a virtual currency, it was relatively easy to mine. Maybe a CPU with strong enough performance could easily mine the currency
as it becomes more and more difficult to dig money, the CPU has already been unable to cope with the huge computing power required for mining, and the terrible performance of the large-scale stream processor parallel computing in the GPU core of the graphics card is more suitable for mining this kind of parallel computing
therefore, today's professional mining machinery has become the world of GPU and professional chips, in which CPU plays the most coordinating role. Moreover, with the increase of mining difficulty, the demand for the display memory capacity of the mine card is higher and higher. A few years ago, 2-3gb was enough, but now 6GB may not be enough.

6. Mining software, from the programming principle, is about large-scale parallel computing
there are many stream processors in GPU of graphics card. For example, the old HD5770 has 800 stream processors, which is equivalent to 800 computing cores. In recent years, the mainstream high-end graphics card has more built-in stream processors and more powerful computing performance. Using GPU for mining operation, the stream processor is used for parallel operation, and the mining program also optimizes the GPU parallel operation, so the operation efficiency is particularly high, and the efficiency of bitcoin mining has been greatly improved
the number of CPU cores is relatively small. At present, the number of the most powerful mainstream desktop processor cores is no more than 10 or 20 (many are logic cores virtualized by hyper threading technology), and the parallel computing power is far less than that of GPU.

7. Yes, but it's estimated that the money won't cover the electricity bill and the time wasted
the efficiency of single core processor with gate level graphics card can not be compared with other high-performance graphics card; You can't dig out an eighth of them
if you don't understand, please ask. If you are helpful, please take it. Thank you.

8. I'm afraid it's not enough electricity. It's not cost-effective.
