You guys sure this miner doesn't submit fake shares to offset the increase in hash-rate?
Because I have no idea how it mines 40-50% faster while using 10% more electricty.
Code refactoring can work wonders. There is plenty of room to optimize AMD code to produce more hash at the same wattage.
Optimized Nvidia code is producing 2+ mhs @ 30w on a 750 Ti and 5.5mhs+ on 780 Tis @ ~250w.
AMD code is so unoptimized for x11 it's nearly criminal.
