Yeah but you're comparing a 95 Watt 2500k Desktop CPU to a 6 Watt N4020 Celeron laptop CPU.
It's really not a fair comparison.
If you want to cite more recent cheap laptop CPUs against a 95 Watt desktop CPU, maybe something like Intel Core i5-8265U @ 1.60GHz would be a better example. It's 1.45x faster than the 2500k and consumes only 15 watts, in a $270 Dell laptop.
