I wondered about that as well. When i see 1 gpu get nearly 1 teraflop eating probably a tad more power than official, say a 250 watt it'll consume. I already use more power now than the specs in fact. Yet even then that's 4 gflop per watt. Last time i calculated bluegene, sure that's probably the previous generation, it was 3 watts per gflop, or factor 12 more power than a Radon HD 7970. Please note that in the statements of most HPC centers claiming blue gene to be energy efficient, usually they do not release numbers. But now the important question, what's price of bluegene per teraflop? It's let's have a look, around a 500 euro or so for a Radeon HD7970 card.
