EWBF behave totaly different
ewbf use a lot GPU power, depending on card near 90% tdp, Memory controller load is ~60%, memory use ~1.5Gb
nicehash use same 10-15% less power, memory load in 2x exe go up to 71%, memory use ~250mb per instance
I presume both have one or other parts done better, so in time i bet we can have more then 300sol (maybe even 400 with OC as 1070 is a lot bettern then AMD in blace algo calculations) on default 1070 or even more, at least more then AMD HW have atm
i managed to do 250 sol at 100 watt like nicehash, but ncicehash was only 220 at the same wattage, so this is actually coded better
