Due to double node jump, the max power should be 0.77W/GH (3.1W/GH divided by 4). Based on everything we know from any chip industry (FPGA, CPU, GPU, etc), that should be the ceiling in power-consumption.

Picture says 600 GH/s @ 350W.
BFL "engineer" (who's area of expertise is Visual Basic and .NET) says 0.77W per GH/s

Unfortunately, multiplication says 600 GH/s * 0.77W per GH/s = 462W

Based on everything we know about multiplication (FPGA, CPU, GPU. etc) that should mean you are just as good at guessing TDP in August of 2013 as you were in August of 2012.

If you read carefully, it's noted that 0.77W/GH would be ceiling due to node jump, not taking any optimization or correction into consideration. The actual numbers are lower, and the ~0.6W/GH was number we decided that was closest to reality + error margin.

1) How are you going to get 400+ watts into 1 card 4 x Pcie connectors Huh

2) You would no be able to disapate the heat that 400 watts would generate for a single fan reference design
3) Your VB.NET power estimates where out by ~ 40% what happened in the last 6 months

Finally 4 how can u as a human be associated with this total joke of a company whose professionalism is NON EXISTANT if not criminal in nature !

Reference style fans work the best by far. You could cool a 400 watt card, depending on how the heat was spread out. A 6990 is about the same. They should be able to make a water block for these pretty easily though. Seems more likely that the card will not run at 400watts. When is the last time they hit the mark guessing wattage?
