(but raw FLOPs doesn't mean actual performance, obviously)
It is an interesting question, but you're counting much more than just the transistors required for the raw flops and don't take into account the increased TEX and MC logic compared to previous generation. And then make a sweeping statement about just the shaders. So you're mixing apples and oranges to calculate grapes and then compare it to apples (I'm sure there is a better car based metaphor for this.)
Edit: really not singling you out, it's endemic and probably unavoidable given the limit amount of data there is in the open...
