Pentium 4 HT 3.8F, November 2004, 3.8GHz, 115W TDP
Core i9-13900KF, October 2022, 3.0GHz, 125W TDP
Of course, the latter does give you 8 performance cores and 16 efficiency cores so performance-per-watt has clearly improved; and it has 'turbo boost'. But in terms of sustained single-core performance? It's clear Intel's attention has been elsewhere. Such as on the laptop market, where power efficiency is king.
