I'm talking specific to these two build to point out differences, rather than going general(though the general differences are quite similar):
AMD build - more cores, less clock speed, more future-proof, cheaper, smoother gameplay(consistent FPS, but lower average)
Intel build - fewer cores, more clock speed, less future-proof, more expensive, faster gameplay(inconsistent FPS, but higher average)
For 60 Hz at 1440p, the Ryzen build is perfect. But, if instead of going to 1440p you want to go towards 1080p at 144 Hz, then the Intel build will be more suited. But since you are going to upgrade the resolution rather than more FPS, the Ryzen build is what I would recommend.
That's the basic performance difference. Part differences include different CPU(duh), different motherboard, different RAM. You could usually keep the same RAM, too, but then the total cost really shoots up.
In short, AMD Ryzen builds are suited for gaming at 60-120 Hz at high details for longer, and Intel builds are suited to play at high refresh rates for lesser time(time as in future-proofing, not playing time).
No problems about the downvote
