Benchmarks of mining speeds with different FPGAs
As we have mentioned earlier, the Bitcoin network hash rate is really high now, and even mining with FPGAs does not guarantee 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 a larger percentage of the total mining power, you will be at a disadvantage, as they are more likely to solve a block.
To compare the mining speed of a few FPGAs, look at the following table:
|
FPGA |
Mining speed MH/s |
Power used watts |
Efficiency W/MH/s |
