I don't know how much this is still true but traditionally Intel processes have better drive currents but more restrictive design rules than their competitors' at a given node. So I'm skeptical that their densities would equal TSMC's in practice. This isn't to deny that Intel 10nm and TSMC 7nm are roughly equivalent, just to say they make different trade offs in a way that chart doesn't cover.

Density is not really an important metric to end users though. What matters is power consumption and achievable clock speeds but these are very difficult to directly compare between processes unless someone has made the same design on both (as has happened with several phone SoCs dual sourcing from TSMC/Samsung).
