Just want to make sure you know what voltage does for chips so we don't' need to go through this exerciser in EE futility down the road.
Chips need a certain amount of resistance for a given node size, architecture, voltage to sustain proper signal cohesion throughout the chip to function properly. What does heat do to resistance in silicon? It drops resistance unlike in other metals it has a different and opposite affect on silicon.
Now signal cohesion can drop due to leakage, which is due to drop in resistance which is do to increase in temperature. To maintain signal cohesion you can use more voltage up to a certain point, at a certain point electro migration, electron tunneling, etc just becomes uncontrollable.
That is why the curves for different architectures for power draw are different even though the nodes might be the same.
When you increase voltage, (unlike frequency) voltage will increase power draw by a factor of powers where frequency has a 1 to 1 ratio of power draw increase.
So dropping voltage drops power draw for a square root. Significantly changing the power draw.
Hopefully this will answer your mythical unicorn understanding of die thinning.
