A 2500K (from 2011) can still beat the pants of off cheap laptops today.

This was shockingly true. I had originally written (and deleted) a reply that discounted what you said not realizing that UserBenchmark had flipped the CPUs I searched for. The 2500K does legitimately stomp cheap laptops.

N4020 vs 2500K: https://cpu.userbenchmark.com/Compare/Intel-Core-i5-2500K-vs...

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.

You know, that's a great point. I was trying to stick to what I thought was the spirit of the comparison by just grabbing the cheapest laptop I could find, but $270 is well within the "cheap" range, and the instructions per watt are significantly higher on that 8265U.

N4020 is quite old too. The N95/100/200, single channel memory aside, holds up pretty well against even 6th gen i5's and has AVX2.

That's true unless you have a Micro Center nearby. I picked up a new Asus laptop with an i5 1135g7 for $250 about 6 months ago. They are selling a new Lenovo with an i3 1115g4 for $200 currently.
