Just because it was made 9 months later means it's somehow an inferior chip?
AM's chip basically what I'd expect a Bitfury 40nm chip to be like. (had they not scrapped it)
This is bitcoin world. 9 months is almost like 5 years. I wouldn't brag with that "on par" chip after 9 months. Maybe in May AM will produce a chip with 0.5J/GH efficiency that is the standard since August.
