(WRONG) So a 9600K has 9-10% gaming performance advantage over 3900X and cost of only $220 with a z390 MB for $120.
The 9600K does NOT have 9-10% advantage over the 3900X. At best in gaming it sometimes is on par but the rest of the games it loses.

Note these are before overclocking the 9600k which overclocks well to 5+ GHz all core. The reviews are stating that the OC headroom on 3900X is minimal to roughly 4.1 GHz.
AMDs best still struggles to beat a NON-OC Intel 9600k costing 56% less in gaming.
