How about GF 14nm HP? That's what IBM is using for POWER9, and it is estimated to launch in the 4 GHz range. Later chips will probably hit 4.5 GHz if POWER8 is any indicator.14nm LPP is perfectly fine (and potentially even the optimal choice) for low clocked, high core count server parts (such as Naples).
The consumer parts definitely need a higher Fmax capability and most likely 16nm FF+ could provide that.
The issue with the newer Samsung process variant is that they are currently not available, and are not proven in practice like the 16nm FF+ is.
