Benchmarks of mining speeds with different GPUs
As we mentioned earlier, the Bitcoin network hash rate is really high now. Mining with GPUs is no longer guaranteed to bring profits. This is due to the fact that during the mining process you are competing with other miners to try to solve a block. If those other miners are running on faster hardware, you will be at a disadvantage, as your hardware can only make a certain number of guesses (hashes) in a given time frame.
To compare the mining speed of a few GPU's, look at the following table:
|
GPU |

Power used (Watts) |
