They didn't. The performance is highly dependent on the game. I know this is true because part of the repair process we do when fixing busted hdmi ports is to test them. We let them run for about 20 minutes on our 4k test tv. We have copies of madden 22 for both, and we let the ai play a game against itself.

Having seen this for dozens of hours on both I can safely say that they are near enough identical.
