The Haswell-E die is composed of 2.6 billion transistors. You have
to achieve phenomenal component reliability for any of them to
work as they leave the factory, let alone years later!

One might argue that all the transistors are created simultaneously in a
single processing sequence, and that the chip is, technically, a single
component.
In general its also a tested component.

so it works to spec or it doesn't.

This is completely impossible to determine. There are far too many paths
through a modern microprocessor to test them all. Hence the Intel maths
debacle of a few years ago.


That's a design issue, not a wearing out issue.
