Intel doesn't lack strong core design people despite what the 10nm delays and having to ride Skylake all these years would tell you, but everything around the core is a real pain for them as they failed to standardize it within the company.
Given that AMD with so limited resources and having inferior process got so close to Intel suggests the other way.
It seems they have solid teams, but nothing extraordinary that other solid teams can't get close to pretty easily.
When I say solid I mean average. Not elite team.
If I was an Intel share holder that was the 2nd most frightening thing to think about (Just after how badly the manufacturing advantage was managed to make it disappear).
