Yes, per core power consumption or better performance per Watt is usually more relevant than the total power consumption. And 1 high-core CPU is usually better than the same number of cores on multiple CPUs. (That is unless you are trying to maximize memory bandwidth per Watt.)

What I wanted to get at is that the pure core count can be misleading if you care about power consumption. If you don't and just look at performance, the current CPU generations are monsters. But if you care about performance/Watt, the improvement isn't that large. The Zen1 CPU I was talking about had a TDP of 180 W. So you get 6x as many cores, but the power consumption increases by 2.7x.
