I wasn't exactly comparing them, as BFL does not make chips.  They sort of implied they do but now they claim they weren't referring to the chips.  They admit their chips are made in Asia.  Taiwan if I'm not mistaken and that's where most of them are.  You can probably count the number of high end and/or custom chip manufacturing plants in the world on 2 hands.  It's just that they sell to one company that sells to another that sells to another that sells to BFL.  The same goes for Marvell and Phision and SiS and even Samsung for example.  I think maybe Nvidia owns their own chip fab plant but I wouldn't be surprised if they actually didn't.
