"(Oh and fun fact: recently I wanted to test out Moore's Law, and see how the RasPi 4 compared to that Core Duo laptop (that I still have!) Well, the 18y-old laptop still handily beat out the RasPi4 in single-CPU performance! Moore's law can't quite make up for opposite market segments)"
shouldn't power consumption also be a factor in comparing performance?
I would think an ARM would use less wattage than a Core 2 Duo.
Certainly, in a MIPS/W or MIPS/$, the RasPi beats the pants off the old laptop (Edit: which I now remember was a Dell Precision M65, which specs say weighed 2.81kg (6.2lb) (likely without extra battery), whereas my current MBP M1 Pro is 1.6 kg (3.5 lbs) so more than half as heavy!)
But I had the mistaken assumption that 15+ years of Moore's Law would certainly leave the old laptop in the dust, in the same way that "modern smartphone more powerful than an old supercomputer". It was interesting to be corrected!
