GlobalFoundries are nowhere near the leading edge on node process, and Intel have opened up their foundries to customers since Pat's return with the advent of IFS: https://www.intel.com/content/www/us/en/foundry/overview.htm...
It never died. It was always there. Pat's just fulfilling the vision Paul had.
Some context from 2013 when they tried their hand at it: https://www.extremetech.com/computing/150217-intel-pumps-up-...
It's funny as a side note that their big foundry announcement at the time was making chips for Altera before the merger, and now Altera is parting ways with Intel after 8 years. Time flies.
