Yes but this is 10 chips because he has 10 chips... And 24W power usage. So yes only bit more then 50% at the moment but there is also efficiently that you need to think about. And overheating. I have a Chili board. And the biggest problem is power supply. It is on the limit and it needs additional cooling or the board slows down by 20%... So because you have save some $ on parts you need now additional cooling(fan and heatsinks) on power supply and that cost more then stronger power supply and uses more power since you need a fan and it runs in less effective part of operational range... Not to talk about lost hashes... So some parts are better if they are stronger...
