As it stands, I was saddened to find out that we were basically losing money or barely breaking even with 0.5-0.7w/Gh miners during 2014-2015 while 21 inc were mining at 0.22w/GH

Intel factories, the documents suggested, were responsible for at least two generations of 21 bitcoin mining chips, a 0.57 w/GH 22nm FinFET chip (codenamed CyrusOne) and a 0.22 w/GH 22nm chip (codenamed Brownfield).

They are quoting 0.22 J/GH at the ASIC chip level, not total system draw at the wall. Competitor ASICS are fairly close, e.g. Spondoolies-Tech RockerBox at 0.35 J/GH (as featured in SP3X and SP20, see https://bitcointalk.org/index.php?topic=521520.msg6519857).

And if Intel really did do those chips then they did a pretty shit job of it.
