Seems like a pretty big catch there. And 7% cost is also pretty big. The fact that TSMC is not interested in FD-SOI is also rather telling.

Honestly, the FD-SOI numbers seem somewhat...hazy. I'd be a lot more favorably inclined if they had some real IEDM papers and I could understand the baseline references. They don't talk about Ion vs. Ioff curves, sub-threshold slopes or any of the real trade-offs.

In all fairness, Intel didn't give sub-threshold slope numbers in their presentation (or Ion vs. Ioff), but:
a) I could probably calculate the SS
b) I'm sure they will have numbers at IEDM
c) Intel's baseline was their 32nm process
