I think they're referring to the Core/Penryn series (the "direct" ancestor to modern Intel x86s). But even that goes back to the P6->P5->486->386->286->8086->8

I think they're referring to the Core/Penryn series (the "direct" ancestor to modern Intel x86s). But even that goes back to the P6->P5->486->386->286->8086->8088->8080->8008->CTC lineage of 50+yrs. It literally just cuts out the few years of the abandoned NetBurst architecture.
