One of the most cost-efficient and cheap Ethereum mining rig with a hash rate of 25 MH/s.
Power cost per day is significantly lower than the already mentioned hardware at $0.4320.
It gives a return per day of $1.21 and therefore a return per year of $440.91.
Its cost per MH is only $7.96 which is highly sought after in the cryptocurrency market. However, it should be noted that Radeon RX 480 has a 4GB version that runs at 7 GHz and a more expensive 8GB model that runs at 8 GHz. Compared to the 8GB model, the 4GB model runs slower by about 2-3 MHz. Hence, the 8GB version is recommended for all mining purposes. The power of Radeon RX 400 can never be undermined, and RX 480 is no exception yielding good power results.
Pros
The most affordable choice for miners Good hash rate and better return per day
Cons
Lack of cooling facilities. Lack of overclocking for GPU frequencies
Buy AMD Radeon RX 480
