If I was you and dead set on upgrading, the only thing I’d upgrade to is either the 13700k or 14700k since it has more P-cores which will help with gaming, but it probably will be negligible in most games at your resolution. The 13600k/13700k/14600k/14700k also comes with more e-cores (IIRC) but they won’t really make that big of an impact in gaming.
Honestly, I’d just OC the 12600k you have and call it a day if you’re gaming at 4k since you’re mostly going to be bottlenecked at the GPU.
Q3 2024 Financial reports shows total datacenter revenue of $14.51B. I’d assume that there’s some discounting going on at that kind of volume.
By comparison, gaming revenue was $2.86B for Q3 2024.
To show the explosive growth:
The Q1 2024 financial report had datacenter revenue at $7.19B. Q3 2023 datacenter revenue was at $3.83B.
