As promises go, I like friedcat's better.

0.2w/GH at 40nm... wow... let's hope Ken can get proportionally efficient chips at 28nm... 0.1w/gh should be possible if friedcat can get 0.2w/gh on a 40nm

It doesn't work like that. Bitfury's 55nm chips aren't half as efficient as today's 28nm chips. They're *more* power-efficient

Yes because bitfurys chips have been designed better, hence my hope that ken can make the most of the power efficiency benefits of a smaller process and get down to the theoretical level of about 0.1w/gh
