Consider them the same!

Does anybody test 6.18 vs 6.12 kernel in gaming?

Generally speaking newer kernels are faster for gaming and gaming distros generally aim for the newest kernel.
I was recently testing stable vs testing branch on my distro with kernel 6.12 vs 6.17 on them and there was a noticable difference in performance in my case. about 10-15% in Dead Space for example.
But that depends on games. There can be a performance gain in general with performance degradation in some specific cases at the same time.

6.18 had an improvement in the memory management subsystem but nothing majour.
