You appear to be correct. I dug around a bit, and on Intel's ARK there are 2 numbers: Processor Base Power (125W) and Maximum Turbo Power (241W, same as the one used with the benchmarks). It appears the Processor Base Power might be a closer equivalent to TDP than the other one. If that's the case, the 12900K is much more efficient than the 8700K.

Can't edit the comment anymore, but I made a mistake. The Maximum Turbo Power explanation is as follows: "The maximum sustained (>1s) power dissipation of the processor as limited by current and/or temperature controls."
Somehow I have misread it to mean that it can peak up to said power limit for UNDER 1 second, which is incorrect - the CPU will run at that limit for as long as cooling allows. The CPU will gulp down ~240W when under full load, as evidenced here at ~24 minutes: https://www.youtube.com/watch?v=fhI9tLOg-6I
