Understanding Graphical Processing Units (GPUs)
A Graphical Processing Unit (GPU), a graphics card, is a hardware component widely used for processing computer images and videos.
How GPU Mining Works
GPU mining operates similarly to mining with ASICs for cryptocurrencies like Bitcoin.
GPU Mining Algorithms
There are several mining algorithms explicitly designed for GPU mining:
- SHA-256: This is the most widely used cryptographic hash function, producing a 256-bit signature for text strings. Cryptocurrencies such as Bitcoin (BTC), Bitcoin Cash (BCH), Terracoin (TRC), and Peercoin (PPC) are based on the SHA-256 algorithm.
- Scrypt: Introduced as an alternative to SHA-256, Scrypt is a less resource-intensive algorithm that measures its output in kilohashes. Litecoin (LTC) is one of the prominent cryptocurrencies that utilizes the Scrypt algorithm, which also features a faster block generation time of 2.5 minutes.
- X11: X11 is an energy-efficient mining algorithm that measures its output in megahashes. Cryptocurrencies like Dash (DASH), StartCoin (START), CannabisCoin (CANN), and XCurrency (XC) employ the X11 algorithm.
- Ethash: Ethash was initially the mining algorithm for Ethereum and continues to be utilized by its forks, EthereumPoW and Ethereum Classic.
Cryptocurrencies Suited for GPU Mining
Previously, Ethereum was a popular cryptocurrency for GPU mining.
Currently, the most popular cryptocurrencies to mine with GPUs include:
- Ethereum Classic
