Clearly we need a better measurement. I suggest picking an open core, then reporting the number that can be produced per square meter. Some choices:

The IBM A2 and the UltraSPARC T2 look like sane choices. Perhaps there is a suitable RISC-V.

So then comparing processes, we could say that process X can do 54255 chips per square meter and process Y can do 83802 chips per square meter.

There is such standard measure but it is the number of transistors for a square millimeter[1].

That is not a great measurement. Transistors can be of different types, each with different value in terms of making products work. Other things matter too: metal, pads, die separation saw cuts, e-fuses, diodes, resistors, and capacitors. Nobody cares about transistors that can't be hooked up to anything.
