People were saying the same about gen 3 a few hundred pages back.
So what? Gen 3 may not be as efficient as some other chips, but it's certainly competitive based on price and is certainly not a complete disaster. So, I'm not sure what point are you actually trying to make. AM Tubes actually have a pretty good value (a combination of efficiency and cost) per volume despite BE200 not being the most efficient ASIC. The price and size offset the efficiency.
The quantity of gen3, despite the failings in the design's efficiency, allowed enough of a margin on the project to stay in the fight for the top chip producer. Gen4 needs to be able to beat that efficiency mark and still make the large-scale quantity orders that we saw with gen3.
Can anyone give info on which of AM's chips are in current mining hardware from hardware partners (namely RockMiner)?
