Does DDR5 memory help gaming performance?

DDR5 mostly helps CPU-bound games like sims, strategy, and esports — titles such as Factorio, Civilization VI, and Counter-Strike 2 can see 15-30% higher fps over good DDR4. But most AAA games are GPU-bound, so they barely care — Cyberpunk 2077 at 1440p ultra with ray tracing shows only 1-3% difference.
