ASICs are built for the express purpose of calculating one specific algorithm. While not as popular as GPUs or ASICs, they have in some cases acted as a happy medium due to their efficiency advantages over GPUs and their flexibility advantages over ASICs.ĪSICs ( application-specific integrated circuits) are the king of the hill when it comes to pure mining power, if the currency for which they are designed is worth mining. While they are more powerful than GPUs, they are also a little less flexible, and can be very expensive, although there are some more affordable options available for certain mining solutions. These devices are more powerful than video cards, but can be reprogrammed to specifically mine different algorithms quite efficiently - even more efficiently than a GPU.

The next stage in mining evolution was the introduction of FPGAs (f ield-programmable gate arrays).

CPUs found it nearly impossible to compete with graphics processors, which caused mining difficulty to ramp up considerably due to their huge advantage in efficiency. So, GPUs offered more mining power and efficiency, but a little less flexibility.Īs miners began building multiple-card rigs, these performance differences became even more apparent.

Video cards, or Graphics Processing Units (GPUs), offer considerably more power than CPUs due to their ability to perform more calculations in the same amount of time.īut some cards are better at performing certain algorithms than others, depending on the manufacturer or even the specific model. It’s kind of like figuring out a combination lock by trial and error, but with a lot of possible combinations. This is generally referred to as “Proof-of-Work,” since the computer must solve a puzzle in order to add transactions to the ledger. CPUs offered the greatest flexibility, and could perform whatever algorithm was needed to solve mining puzzles for block rewards. If you go waaaay back (about nine years ), you would find that older cryptocurrencies were mined with CPUs, the basic processor in any computer. source: Here’s what you need to know about mining equipment: Each cryptocurrency uses a distinct algorithm, which incurs important tradeoffs in centralization, equipment and network security. So you might be thinking it’s time to fire up your own rig again, or perhaps order parts and set up your own little mining farm for the first time.īut before you start counting your bitcoins, it’s worth taking the time to understand some of the fundamentals of the cryptocurrency economy.

In the past couple of months, hashrates have been racing higher, indicating that some large-scale miners may be back in business. Cryptocurrency prices are back on the rise, and the number of miners is rising with them.
