Of course, you wouldn't fab the current design on TSMC 5nm as they'd have more transistors to play with.
It's still not a level playing field as they'd be implementing different ISAs. If Intel acquired an ARM architecture license and then designed an ARMv8 CPU with identical constraints then you'd get a valid comparison.
Although you'd likely have different IP in other areas which could skew the results.
If you're looking for a comparison of the ISA's I think the decoding issues / execution width points to a likely ARM win still - only question is by how much.
