How many GH per watt do ASICMiner et al get?

It's quite variable, based upon the stats in the main chart ("Complete ASIC Hardware")

http://mining.thegenesisblock.com/

ASICminer (blade) is 7 Watts/GH, Avalon 10, BFL 6, BitFury & KnC 1-1.5

So, the mining power consumption has broadly been in 3 levels:
650 W/GH until end-Feb
8 W/GH March through June
2 W/GH Since July but will drop below 1 early next year.

Rough numbers, but perhaps usable

This is the problem:

At least they understand that ASICs are more efficient, but logic won't get in the way of a FUD headline.
