The following points will help you decide whether ASIC or GPU is the better choice-
Hash rate
Mining cryptocurrency requires significant processing power. ASIC has the highest hash rate. Once the miner has solved the puzzle, a new coin will be created. While your hashing rate may not be a major factor in the rewards you receive, it is still important to have mining equipment that will complete the task quickly. A mining equipment with a high hash rate should create a safer blockchain network. This is the standard requirement at all times.
ASICs have a higher hash rate than GPUs, and are therefore more powerful mining equipment.
Easy of Use
It is evident that miners will choose the equipment that is easier to use if they want to mine cryptocurrency efficiently. ASICs allow novices to start mining with just a few simple steps, without the need for expert assistance. Mining efficiency is directly related to profitability.
But GPUs are the more difficult mining equipment to use for cryptos. ASICs offer a more attractive option to miners due to their ease of use and monitorable interfaces.
Versatility
The mining setup of ASICs can be easily done by reading the manual, watching a YouTube Video, or even using a blog. At first, the energy consumption was an issue. The latest ASIC miners, however, are more efficient per hash due to the fact that they consume less energy and have been specifically designed for mining a particular cryptocurrency.
Setting up a GPU miner requires more expertise and complexity. ASICs are smaller and require less maintenance. ASICs are more versatile than GPUs because they have an easy setup, can be modified to reduce energy consumption and require less maintenance.
