A lot of people answering, and not even owning a intel cpu, that‘s funny.

I did it, 12700k to 14700k. Same mobo, ram. Added a contact frame, and needed to underclock and undervolt (as i did with the 12700k) with a NH-D15. After a weekend of fiddling around i‘m at 35-37C idle temp with fans off and at max 90C in CB24 mt. Scores are way above anything the 12900k could do, with way less voltage. Also in the most demanding games it gave me a palpable uplift in fps. But i‘m talking high end. I have a RTX4090 and i can see it in maxed out CP77 (pathtracing) i can see and feel it in msfs20 in VR, also simracing, Automobilista2 VR. I really see and feel the difference.

But if you have a mid tier gpu or even a 4070/4080 i don‘t know if it really makes sense. Depends on the game or workload. If you can use your old mobo and can sell the 12700k for 200€/$ go for it. If it makes you happy, go for it! Don‘t expect a generational uplift in performance though. 7-14% depending on the game/programm.

Well, either this video And many reviews are lying, or maybe it is you.

Wrecks it with 7fps lead at 1080p

And is behind at 4k…
