I actually attended the FD-SOI symposium at IEDM and I've talked to multiple vendors about it.

And as much as the SOI consortium would like to believe that it's suitable for mobile, their actions indicate otherwise. Even on their roadmaps, they show that the first users will be high performance logic, and then eventually mobile devices.

The guys at STM believe in FD-SOI, but Global Foundries is much more cautious and it's not clear which way IBM leans.

Even if I look at this presentation though, they are claiming a 40% improvement in power by dropping Vcc by 150mV. Intel got a bigger improvement with FinFETs. I also see little in the way of comparison to FinFETs in their presentations, only to bulk CMOS and PD-SOI.

Also, I think Intel dismissed FD-SOI for other reasons. They only recently were able to tape out the Cortex M0, in December. That's a very simple chip.

Intel had to tape out Ivy Bridge months before that, and it wasn't a synthesized chip. So I suspect that FD-SOI might have had too many unknowns and too many risks for Intel to chance it - especially given the cost premium.

I'm sure that Intel has experience with FD-SOI and didn't mindlessly reject it.
