The encrypted cryptocurrencies such as Bitcoin, Litecoin and Dash can be mined with ASIC miners. However, due to different algorithm settings, some currencies such as Ethereum and ZEC need to be mined with GPU miners currently.

Nowadays, AMD and Nvidia are the two types of graphics cards which are most commonly used for mining. The miner with 8 AMD graphics cards to be introduced today is Antminer G2 produced by BITMAIN, the well-known cryptocurrency ASIC miner manufacturer. Now, let’s have a look at the performance of Antminer G2!

Performance Test

The noise of Antminer G2 is relatively big. The measured noise about 10cm away from the miner is about 90dB while about one meter away the noise is still 80dB.

The nominal hashrate of Antminer G2 is 220M. According to the actual 12-hour test, the hashrate is maintained at about 230M in stable operation, which is slightly higher than the nominal value. The nominal power consumption is 1200W and the actual tested value is 1222W, which is also a little higher than the nominal value. The ratio of power consumption and hashrate per M is 5.31W/M.

 

Summary

The GPU Antminer G2 runs stably and the actual values of hashrate and power consumption are higher than the nominal ones. The only flaw is the noise which can be heard even the door has been closed.

Ethereum is very promising. In 2017, the price increased quickly and it’s very profitable to mine Ethereum with Antminer G2. Those who want to buy GPU miners can take Antminer G2 into consideration.
