Nvidia on new self-driving system: “basically 5 years ahead and coming in 2017”

That's a big "+" on your figure - it's about 300 Watt-hours per mile, or 3600W constantly, if you're going 60 mph. For comparison, one horsepower is about 750 watts - a Tesla is a very low-drag car.

Anandtech reported [1] that the TDP of the whole board is around 250W. The Tegra SoCs are probably around 10W, but that doesn't get you much in the way of GPU horsepower.

Yeah, I screwed up the math.

Point stands though.

I don't think it does still stand when you were off by an order of magnitude.

Yeah, in the wrong direction, I underestimated the powertrain consumption, so the power cost of the computer is relatively even smaller.

The point I made missed the point though, it apparently isn't the energy consumption they are concerned with, other people in the thread are pointing to limiting/getting rid of the heat being the main concern.
