A mining machine is commonly referred to as a mining device. Mining machines mainly include ASIC miners and GPU miners. Some coins support FPGA miners, CPUs, or other equipment, but the proportions are relatively lower.
An ASIC miner is a highly customized professional mining machine that generally has a high hashrate but supports only a few coin types because of its fixed algorithm. For example, Ant S19 Pro can only mine SHA256d algorithm coins (such as BTC, BCH, DGB, etc.). GPU miners are more flexible and support mining for almost all coin types. However, the hashrate of GPU miners is relatively lower than that of ASICS.
Relative to ASIC miners, GPU miners are more flexible. Coin types can be easily switched depending on market factors like prices. The residual values of GPU miners are also higher as second-hand graphic cards can still be used and sold on markets.
You can choose to buy graphics cards and assemble them individually or directly purchase custom-built GPU miners. Assembling GPU miners mainly includes GPUs, CPU, RAM, hard disk, motherboards, and power supply components.
Regardless of dependence on ASIC miners or GPU miners, the process of profit generation is done through fixed investments in equipment and electricity. Market fluctuations are also an important factor. You can use our advanced mining calculator to estimate the payback periods or refer to the daily output of popular miners for evaluation.
