When I replaced my Ryzen 9 5900X with a 5800X3D a couple of years ago, the performance improvement was obvious almost immediately. Some games, like Valorant and Battlefield 2042, were clearly CPU-limited at 1440p when I had the 5900X, often leaving my RTX 4090 sitting at around 70–80% usage. After the upgrade, both ran significantly better, with GPU usage improving across the board. It was so good that I never felt the need to ditch AM4 unless I wanted the RTX 5090.
