> Older computers usually guzzle power, especially if you look at the absolutely awful Pentium4 systems.

https://en.wikipedia.org/wiki/List_of_Intel_Pentium_4_proces...

The Northwood chips were 50 to 70 W. HT chips and later Prescott chips were more 80 to 90 W. Even the highest chips I see on the page are only 115 W.

But modern chips can use way more power than Pentium 4 chips:

The i5-14600K has a base TDP of 125 W and turbo TDP of 181 W, and the high-end i9-14900KS is 150 W base/253 W turbo. For example, when encoding video, the mid-range 14600K pulls 146 W: https://www.tomshardware.com/news/intel-core-i9-14900k-cpu-r...

More recent processors can do more with the same power than older processors, but I think for the most part that doesn't matter. Most people don't keep their processor at 100% usage a lot anyway.

As I said in a sister comment here, you can't compare CPUs by TDP. No one runs their CPU flat-out all the time on a PC. Idle power is the important metric.
