Re: Black Arrow 28nm 100Ghash Bitcoin ASIC from $1.99/GH/s, miners from $2.97/GH/s

Speaking as someone who has their products in hand, no they dont. They get effective about 1.1-1.2w/gh.

Rockminer is not a great example, they run their core VDD at 0.72v whereas the BE200 can go as low a 0.55v.

What's the W/GH ratio for end system at 0.55v?

Who knows, they quote only the chip specs, have to wait until someone under clocks a system properly.
