If perf(r) modeled as sqrt(r), the total computation power varies given different partition condition even the total number of transistors is the same.

No. perf(r) as sqrt(r) indicates as you double the transistors, performance increases by 1.4x. Power still remains proportional to the number of transistors.

Oh. Sorry to create the confusion. What I'm referencing is the computation power not the physical power.
bpr
Yes, then you are correct. Smaller cores give you more computational power, if you have the parallelism to use them.

i.e. n/r * perf(r) is different given different r, even the total number of transistors doesn't change.
