13th gen is faster, but 13th and 14th gen is under fire currently for high failure rates. As others have stated, a 12900k is closer to a 13700k in core count or even a 13600k in actual performance in say, gaming. The only advantages of the 12900k are stability (since it isnt affected by the issues the newer chips are) and sometimes price. Like if you got a microcenter in your area and you can get that sweet sweet $400 12900k bundle, and you arent interested in AMD, 12900k all day. otherwise it's kinda overprice for what you get and you can do better with 13th gen assuming you dont get a lemon.

12900K or 13900K
If you are looking at the i9 12900K perhaps you should also look at the i7 13700K. It has the same core count as the 12th gen i9 and offer 95% of the performance of the 13th gen i9. ...

11900K vs 12900K vs 13900K
Well I'm your guy because I have the same setup as you. My friend has a 4090 and a 13900k. At 1440p maxed he gets 220 to 270fps in ground war. I, with my 11900k and 4090, get 144 to 180 fps in ground war. (Hovering at 160) in 6v6 he gets basically 300fps at all times, I get 170 to 220. Sometimes it goes higher but not usually. The 11900k bottlenecks the shit outta the 4090. The 13900k still does but not as much. For instance his GPU utilization is always at 85 to 95% were mine is 50 to 60%. The 11900k really holds this card back. I'm happy with my performance though and am gonna wait for the 14900k as it'll run on TSMCs 7nm architecture. Then I'll really be able to see what this card can do lol. If I were you I'd wait for the next Gen of CPUs. (but if you're impatient get the 13900k and you'll see a fucking massive performance boost) More on reddit.com

Is it worth upgrading from i9-12900K to i9-13900K?
If you currently have the i9-12900K, then you shouldn’t go for the i9-13900K unless you want the latest and greatest chipset. Yes, the i9-13900K is quite an upgrade, but we don’t think you should swap your current i9-12900K for it.
