IIRC lately, Intel's real TDP under serious load is almost twice as the public value. I guess it's also valid to their server parts to a certain degree.
Intel has a habit of hiding some ugly things about their chips under NDA until it has competition or the chip is last-gen. The uglier thing is they're adding these values back to their documents later as a revision and telling look, it was already there! (cough, AVX base frequencies, cough!).
Competition and being a very big company changed them... a lot.
Sadly very few companies are integrating the higher end Zen chips.
