It's no secret that user bench is a notoriously bad source when comparing amd and intel, or amd and nvidia. For whatever reason the people running the site have it out for team red, the 5000 series in near every benchmark and game beats intels 11th gen handily, yet almost all of 11th gen is ranked above almost all of ryzen 5000. The fact that the 5800x3d and 12900ks trade blows yet the the 12900ks is 3-400$ more should be the real take away. If you purely want the best gaming experience while still being budget conscious then the 5800x3d is the route to go. If you want the balls to the walls best system price be damned then go 12900ks. That said, early leaks of zen4 and intels 13th gen have AMD utterly destroying intel and those chips are coming just a bit later this year. If you can wait another 6 months to upgrade or buy, wait.
