Techpowerup did an article on lowering power limits on a 12900k, all the way from 50W to 241.
Gaming performance, for what games they tested anyway, did not change much down to 125W for PL1 and PL2. Below that there was a performance decrease.
Application / multithreaded performance would drop a decent amount with the lower limits but gaming you can cut power quite a bit from stock before you will notice a change.
