Regarding power consumption, Radeon 5970 and 5870 both consume more power than our card does, the very reason we took this design approach.

Yeah, but what about when the power doubles from your pre-fab estimates, like every other chip you've built?

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.

HAHAHAHAHAH.  WHAT!? The calculations for transistor gate energy are pretty complicated, and they certainly aren't linear with respect to surface area. and I think at 28nm you have more leakage which leads to more waste energy as well.

I think this shows you have absolutely no idea what you're talking about.
Where is TheFiend when you need him?

I would love to hear his input on this and many other crazy claims by BFL.
