But could they be better utilized than 4 cores with the same energy budget and cost?

Most of the time, most applications use barely any CPU at all. What you really feel is the moments when a single application suddenly needs a lot of CPU, and when it isn't parallelized it wants a single fast one, not several slower ones. I almost never see my system under 100 % load, but I regularly see processes maxing a single core.

You'd think most apps could be built to utilize at least 2 cores, instead of pinning just 1 core.
