> even when Intel TDP was 20x worse than today.

When has Intel's real, advertised, or specified CPU power consumption or TDP ever been 20x that of the i9-13900KS?

Core i9-13900KS consumes 150W with 24 cores (8P+16E)

so an average of 6.25 watts per core

which is less than a Pentium 90, a 1994 CPU running at 90Mhz

in absolute is not a 20x worse TDP, but it is relatively to the gain in frequency and performances (more than 20x actually)

No, the 13900KS has a nominal "TDP" of 150W. That's a marketing number, not a measurement and not even a control target parameter for the default boost management settings. Out of the box, a 13900KS in a typical desktop motherboard will happily draw more than twice that, indefinitely, if you can cool it and have a workload that can actually keep all of those cores busy: https://images.anandtech.com/doci/18728/13900KS%20Power%20Gr...

If you want to compare per-core power, you either have to use a power number for a workload that's actually loading all the cores, or divide the measured power by the number of cores actually in use.
