In any case, my major point was that power really does matter and I think either of these ways of reasoning shows that it does matter.
Using your assumptions that BFL is wrong and that you know bASIC's power figures that Tom hasn't released yet ...
Huh? No. Power matters no matter what sane figures you plug in to either my deprecation free model or sturles alternative. Depending on the power costs you assume you might find that bASIC comes out ahead, or you might find BFL does (which is what I expect based on my prior power estimates at 130nm). But it certainly
matters as differences in the figure change which product is more cost effective.
300W? So BTCFPGA is going to be 5x less efficient than BFL @ 60W? That seems a little high to me, but maybe you know better than I do. Let's see what cablepair says..
It's not surprising at all if they're on different process (or have made some improbable breakthrough against SHA256). And I can't believe BFL's numbers at all if they're not on a substantially more efficient process than 130nm.
