Best choice for you currently is a 12900k. It's the fastest gaming CPU, has DDR5, PCIEv5 and also has an upgrade path to a new architecture, Raptor Lake.
AM4 is dead - all it's getting is a 5800X with more cache, which will release in Spring. I doubt it'll beat a 12900KS (or a 12900k with small overclock) in gaming performance. It lacks the cores to beat it in MT performance.
Either that or wait around a year for AM5 and Zen4, to see how it competes with Raptor Lake/Meteor Lake, though you'll spend a year suffering slow performance for this privilege.
Zen4 is also an unknown, performance wise. It could be another Bulldozer FX-9590 scenario, which only the most special AMD fan bought (it had terrible ST and MT performance, with huge power consumption), or it could be amazing and have 20% more IPC than Raptor Lake/Meteor Lake.
Zen 4 release date is also unknown. AMD said at CEX that it's "on track" for 2H 2022 - though this could easily be delayed to 1H 2023 or later. Also, they may not be able to get the wafers they need from TSMC, as they have to beg for these and compete with Apple for supply.
Fastest cpu gaming is amd 5800x3D.
(soon zen4)
Your comment is riddled with guesswork and your intel bias is showing.
Intel is done.
