Dude, your question shows exactly how far back you read... The whole reason this shit about bitfury cropped up is because people were claiming ridiculous numbers on the efficiency of a 65nm chip which for all intensive purposes should not have been possible and then transformed into an argument over whether or not the BF chip was more efficient than KNC's. That was the point he was getting at I believe, people where claiming some crazy shit, with out any proof to back it up...
...
The KNCminer specs from there own data is Energy consumption: 1.6 W/Gh/s. the Bitfury is 1.0W/GH/s what's so hard about that to understand? The Bitfury is more energy efficient, though they both are pretty good.

The KnC 1.6 is at the wall though, right? What is bitfury's at the wall?

-MarkM-


I asked KNC to confirm that the 1.6 J/GH is at the wall but they did not.  Given that the at the wall efficiency will depend on the user supplied power supply efficiency I think the most probable scenario is that the 1.6 J/GH represents the entire system DC wattage.  At the wall would be ~10% lower for the average 80Plus Gold PSU.  Unless KNC states in clear terms the at the wall/plug efficiency we won't know until some units get to users.
