Well, obviously the "will ever" bit is nonsense. There will be a more powerful, more efficient miner within the next 2 months for sure. its called progress
Have you heard about more powerful electrically efficient chips being produced? I sure havent...cant pull anymore power from a consumer standpoint
What's the wattage per GH on this "most powerful, electrically efficient miner that will ever be produced"?
Well its the 20NM chip...its the best. Its a 30% reduction per GH from the 28NM chips used in saturns and jupiters. I think if something else bigger was coming out, you would of heard about it by now...you cant go any bigger than 4TH on a consumer power supply...Not the way I see it at least
