Flagship Rematch: Ryzen 7 5800X3D vs. Core i9-12900K

A fresh gaming benchmark revisits the Ryzen 7 5800X3D vs. Core i9-12900K matchup.

Intel’s 12900K can pull ahead with fast DDR5-7200, but its lead shrinks or disappears on DDR4-3600.

In games like Rainbow Six Siege X and Battlefield 6, memory speed makes a major difference in frame rates and 1% lows.

The results also underscore the limited upgrade path for AM4 owners, even as chips like the Ryzen 5 5500X3D and Ryzen 7 9700X enter the conversation.
