And that means in Low Power segment ARM realm supreme. Not likely to be dethrone in the next coming decade. As they have solid roadmap and pretty much the plan for next few years are all set and done.
So where does it left for Power? Coming from IBM they are very likely to be expensive. IBM has never been known to iterate as fast as Intel. Let alone ARM which now offers all sort of ARM chips for everything except High performance in their portfolio.
I just dont see how this could change anything.
