Intel owns outright most of their fabs that produce their processors. Intel is the fab, hopefully they trust themselves.

AMD on the other hand, is going fab-less for at least some of their products. TSMC was mentioned in the past as being a partner. So you'd have to trust both AMD and TSMC.

I have heard it joked that Intel is a fab with a small design firm attached.
