In late 2000, Intel promised that Pentium 4s will hit 10GHz by 2005 – on a presumed 130W power budget –, after the last 5 years saw clock speeds increase from 150MHz to 1.4GHz for the P6 architecture (at a stable 30-40W power budget), and other vendors saw similar increases.
Over 20 years later, we're barely scratching the 6GHz barrier with an opportunistic turbo mode that isn't guaranteed to kick in, if your cooling isn't up to the task of dissipating a record-breaking 250W of peak power consumption.
