Well, I'm about to write a major rant here. Here it comes:
Phone's CPU and memory, while important, are NOT what make the phone FEEL fast. It's the OS. Ask why iPhones have always been traditionally behind Android phones on memory capacity, with only recently has memory sizing increased?
For pure benchmarking of mobile CPU performance, no Android phone is faster than Apple's latest chip, especially in single-core and GPU (aka gaming) scores. The latter is looking particularly terrible for Android.

https://browser.geekbench.com/android_devices/oneplus-13 = I picked it since, in my quick search, it was reported to be the fastest Android phone.
If you could swing OnePlus 13 - I'd say go for it, but like I said, the OS matters more than pure CPU speed (or ram)
But as mentioned had mention Google's Pixel line is one I'd recommend, and not necessary to be the fastest, but to give you the FEELING of a faster phone for far longer, as it's less encumbered by 3rd party junk software (looking at you, Samsung)
P.S.: Judging CPU performance in terms of gigahertz is just plain stupid in 2025.
P.S.S: With Google potentially looking to lock down Android very soon, to create the same closest app garden that Apple got slack for so many years, I must ask, what is the reason to get an Android phone today?
(I mean, stuff like ReVanced I get, but for most users it won't matter)
