For what it's worth, Intel has been using Arm cores in its products for years. Some we know about, others we do not. Some Intel products contain solely Arm cores.
As for their own custom cores, Intel has had an Arm architecture license for around a decade, if not longer.

How much has Intel used that architecture licence? Golden question. Given that Arm's own cores go from the M0 for microcontrol, up to the X1 for performance, and R-series for real time, and lots in-between, it's hard to say.
A modern CPU has a lot of microcontrollers.

Just don't ask what secret sauce they already add for big customers.
Intel also does partnerships to build security stuff like this that next-to-no-one knows about. Who knows what additional control was built into the Skylake silicon to enable this solely for Tsinghua.
