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!
