What Is a Mining Rig?
A mining rig is a computer that is customized for cryptocurrency mining. A miner is used to help process transactions and secure the network of a cryptocurrency that uses a Proof-of-Work (POW) algorithm. A mining rig constantly performs hash functions to be the first to create a new block of transactions that can be added to the blockchain. [link widoczny dla zalogowanych]

Types of Mining Rigs
There are several types of mining rigs that have been popular since the emergence of Bitcoin. Due to the historical profitability of mining, manufacturers keep pushing the limits of what is possible to achieve a higher efficiency and thus profitability. We look into the different types of mining rigs below and how they have changed the mining industry over the years.

What Is a CPU Miner?
Mining originates from the CPU (Central Processing Unit), which is present in any personal computer. In the early days of Bitcoin this type of miner was all that was used. Computers are multi-purpose tools, however. They are not optimized to be as energy efficient as possible in one specific type of calculation. As mining competition increased, CPUs quickly became outclassed, which is why it is often mentioned that mining from a personal computer is no longer profitable.

What Is a GPU Miner?
A GPU mining rig is a computer that is put together to mine cryptocurrencies. It can look like a regular personal computer, but it typically has several GPUs (Graphics Processing Units) connected to its motherboard. [link widoczny dla zalogowanych] As a result, it has significantly more mining power than a CPU. The first GPU mining rigs in 2009 introduced a ~332% efficiency improvement over CPU miners.

What Is a FPGA Miner?
A FPGA (Field-Programmable Gate Array) is an electronic circuit that can be programmed to execute specific operations. It can therefore be used to mine a specific cryptocurrency, and then reprogrammed to mine a different one. While this sounds great in theory, in practice this process is difficult, and FPGAs have a lower energy-efficiency than ASIC miners. This also explains why they are not used much for mining anymore. The first FPGA mining rigs in 2011 were 615% more energy efficient than GPU miners.

What Is an ASIC Miner?
The most popular mining rig today is the ASIC or Application-Specific Integrated Circuit. Unlike the other processing units, this is a chip that is customized and manufactured for a particular use, rather than a general-purpose use. [link widoczny dla zalogowanych] One of such particular uses is mining. When an ASIC is optimized for mining, it will far outclass the power efficiency of other computers. This makes trying to compete with ASIC mining rigs impossible without using ASICs. The first ASIC mining rigs in 2013 were 460% more energy efficient than FPGA miners.
