Some quick maths?
4.9GHz vs 4.7GHz max single core boost = 4% difference in clock speeds (being in Intels favour)
1717 vs 1674 is the max single thread score of both CPU's mentioned (being in Intels favour again)... but when we take 1717 (the score of the mentioned 11900T) and reduce it by 4% to take into account clock disparity between CPU's, we actually get a score of 1648 for the Intel part... less than the 5800X's score, at the same clock speed.
Or, in "points-per-ghz":
1717/4.9=350.40
1674/4.7=356.17
Maybe I'm mistaken, but that doesnt equate to a 2.5% lead.
Edit to ask
@W1zzard for employment due to my amazing mathematical skills. Any chance?
