GPUs were able to solve many mathematical calculations effectively when compared to CPUs. GPUs can also be programmed to compute specific algorithms. Thus, GPU mining came into practice.

    GPU mining enabled miners to mine Bitcoins efficiently and earn more rewards. However, since GPUs were highly efficient than CPUs, the price of GPUs became expensive, almost twice the cost of CPU devices. Not many crypto mining enthusiasts could afford the huge cost, which quickly paved the way for the next generation of mining equipment, FPGA.

    3. Field Programmable Gate Arrays (FPGAs)

    Launched in 2011, FPGAs compute mathematical algorithms much faster and mine cryptocurrencies quicker than GPUs. In fact, FPGAs are highly flexible and can be programmed and reprogrammed to solve various mathematical problems and mine different cryptocurrencies. Thus, FPGAs can be customized to mine any cryptocurrency effectively.

    FPGAs have a longer lifespan as they can be repurposed for any algorithms. However, building FPGA devices is challenging as they must be programmed and architected to run on customized code. That again led to ASIC miners.

    4. Application Specific Integrated Circuit (ASIC)

    Unlike CPUs, GPUs, and FPGAs, ASICs are designed and optimized for specific algorithms. Hence, they are more efficient than general-purpose devices. For example, today, we have ASIC miners for specific cryptocurrencies like the Kadena miner, Kaspa miner, Bitcoin miner, etc. These miners come with excellent hash rates, high speed, and energy efficiency, optimal for mining that specific cryptocurrency. Thus, ASIC miners are popular among crypto miners and are the most opted mining hardware. On the flip side, ASICs are slightly expensive as manufacturers need specialized resources and expertise to design ASICs.
