FPGA mining machines are mining machines that use FPGA chips as the core of computing power. FPGA mining machines are one of the early mining machines. They first appeared in late 2011. They were once promising at the time, but their active period was not long. They were gradually replaced by ASIC mining machines and GPU mining machines.

To understand FPGA mining machines, we must first explain what FPGA is. FPGA(Field-Programmable Gate
Array), the Chinese name is field programmable gate array. A more popular understanding is that FPGA is a large number of logic devices (such as AND gates, NOT gates, OR gates, selectors) packaged in a box. How to connect the logic components in the box is all up to the user (programmer) to decide. It's like we bought a set of Lego toys, and it's up to the child how to put them together.

This is easy to understand. By writing different programs as needed, the FPGA can implement any function, and mining is naturally no problem. And due to the high flexibility of FPGA, it can not only support the SHA256 algorithm of Bitcoin, but also the Scrypt algorithm that GPU mining machines are good at.

During the period when FPGA mining machines were active, compared with CPU and GPU mining machines of the same era, although FPGA's computing power performance was not superior, its power consumption was much lower, and its overall power consumption ratio was very high.

However, with the emergence of ASIC mining machines, FPGA mining machines have gradually faded out of people’s sight. Because ASIC is built for specialized functions, it has more advantages in computing power and power consumption than FPGA, and the development difficulty is much lower than that of FPGA. Therefore, FPGA mining machines are basically no longer seen, replaced by ASIC mining machines and GPU mining machines. machine.

Of course, FPGA mining machines are not dead. There are still teams developing new FPGA mining machines, which may one day become mainstream again.
