Laptops with active cooling however...

How do you see active cooling playing a role ?

Are you thinking, for example, at reduced fan noise if we remain below
a certain OPP ?

Are you factoring fans power consumptions into the overall P consumption ?

Nothing as fancy as that; I just figured that with a larger cooling
capacity, you can push chips higher onto that curve past the optimal
IPC/Watt point. Make it go fast etc..

That very concept of "optimal IPC/Watt" point is not something easy to
define considering a monotonic function and without considering the
specific optimization goals.

It really sounds like saying that an LP problem has a unique solution
independently from the optimization function.

Do you think we should "mandate" an optimization function from kernel
space? I'm not saying it does not make sense, but I find it at least a
strong implementation enforcement.
