Compared to APW3++, the rated power of APW7 has increased by 200 W. And we can understand from the below APW7 Efficiency Curve diagram that its efficiency is 95% which increased 1.5%.
We are using APW7 to run the X3 Antminer (with rated Power is 500 W). We see that the power consumption of 490.8 W (on the left picture), so the load percentage is 490.8/1800 = 27.27%
Whereas using APW3++ to run X3 miner has a power consumption of 498.2 W (on the right picture), so the load percentage 498.2/1600=31.14%
We can conclude that APW7 could save around 4% of the power used. This would reduce the cost of mining.
APW7 has better heat dissipation, which means APW7 can work in a higher temperature environment.
