A massive IPC jump like that is only going to come with a big change to the core design.
Why the heck would AMD spend millions designing a new core, on a type of process it's never used before, porting its GPU to a process it's never used before, just to target a tiny niche of the market with wafer thin margins?
Most of the design methodology of 22FDX is from low-power Bulk. It isn't radically different compared to the SR/XV process, while it might adopt some BD/PD optimizations. Relative to Stoney, a 22FDX APU would have higher margins.
22FDX/12FDX <== More lucrative than anything on => 14LPP/7FF.
28nm FDSOI => Cortex-A9 @ 1V = 2.3 GHz
22FDX => Cortex-A53 @ 0.9V = 2.4 GHz
22FD w/ FBB = Cortex-A53 @ 0.9V+0.9Vbb = 2.5 GHz (0.9+0.9 should equal 1V without Vdd degradation and lower power consumption.)
Production ramp for 28nm at GlobalFoundries = 2012
Production ramp for 22FDX at GlobalFoundries = 2018
Historically, we have a bit of time still before 22FDX if we take 28nm into consideration.
