As you suggest, the performance benefits of increased clock speeds is highly workload specific. I agree. It's roughly linear for some workloads up to a point, and highly non-linear for other workloads (especially memory bandwidth constrained workloads, which is a relevancy case given that it's SoCs we compare, not stand-alone CPUs). Yes, target clock speed is a big part in considering power usage, but also fab process, memory architecture, etc. Adjusting for clock speed makes no sense, though adjusting for power consumption might.
