Again... What other explanation do you have? Have you ever idea of what the FO4 is? Enlighten me, please...
What other explanation do I have for an AMD CPU of an approximately similar approach on an approximately equivalent process to its Intel counterparts achieving approximately similar clock speeds?
Nothing magical - just that its a fairly converged solution in both design and build which will result in fairly converged results.
Fixating on a measurement of inverter delay, which just happens to also be used as a unit of nomalisation means nothing. You've no idea of the exact correlation of a normalised F04 to actual results from a given process, nor do you have any means of comparing across uArchitectures. For all we know, the FO4 of Zen and of Haswell could be closer than the end frequencies of both products - the difference resulting mostly from the process and not the design.
Your broadly right in pointing at FO4 as a means of measuring design speed - but its too complicated to simplify to one parameter. You should know that.
