I'm choosing a processor mainly for gaming, so productivity performance and extra cores aren't important to me. How does Intel's Core Ultra 7 270K Plus compare with AMD's Ryzen 7 7800X3D, and which one should I buy for the best gaming performance?

The 7800X3D is generally the stronger gaming CPU, especially when you’re CPU-limited at 1080p or 1440p with a very fast graphics card. Its 3D V-Cache helps a lot in many games, while the 270K Plus is more competitive when paired with fast memory.
For gaming alone, I’d choose the 7800X3D unless the 270K Plus is substantially cheaper where you live. The Intel processor can be a good value and is much better suited to heavy multicore workloads, but it doesn’t consistently outperform the 7800X3D in games. If you already have a capable CPU, waiting for a later generation may make more sense than upgrading now.
Your graphics card and resolution matter more than many comparisons suggest. With a high-end card at 1080p or competitive settings, the 7800X3D’s advantage is easier to notice. At 1440p or 4K with mostly demanding AAA games, the difference may be small because the GPU becomes the bottleneck.
If you’re buying a platform for future upgrades, AM5 is also the safer choice because you can potentially upgrade the CPU without replacing the motherboard.
The two can be fairly close in average gaming performance depending on the game, graphics card, resolution, and memory configuration. In some newer or memory-bandwidth-limited titles, Intel may even win, and its 1% lows can occasionally look better at 4K. However, that isn’t the typical result across a broad gaming lineup.
There are a few games where the Intel processor can beat even newer X3D chips, but those are exceptions rather than the general rule.
With slower RAM, the 7800X3D tends to pull ahead more clearly. The Intel chip needs fast memory to get close.
