When the Intel story becomes obvious, you will have missed it.
'Intel's fabrication will prevail. The only question is how long it will take.'
This advantage has to be actually demonstrated in the designs at the lower processes though. The facts are that all Intel has shown are incremental improvements in both clock speed and low power while ARM has shown staggering improvements in clockspeed, ipc, multi-core with new architectures going to lower process sizes and this does not seem to be stopping any time soon.
Samsung have gone from 1.2 GHz dual-issue A9 at 45nm to 2 GHz triple-issue A15 at 32nm. What Intel did going from 45nm to 32nm in comparison was only increase Atom clockspeed from 1.86 GHz to 2.13 GHz ,albeit at lower power.
Ultimately all this fabrication talk is just grandstanding hand and arm waving without discussing the actual designs that will be competing against each other which show that ARM designs are remaining very competitive despite being built on larger process sizes.
