AMD’s 3D V-Cache processors are some of the fastest gaming CPUs. More affordable than its Intel rivals, the Ryzen 7 7800X3D offers similar or superior frame rates with a significantly lower power draw. At the time of reporting, the 7800X3D is priced under $400 and is as fast as the $550 i9-13900K. In this comparison, we’ll pitch these CPUs across 22 games, including ray-tracing.

AMD Ryzen 7 7800X3D vs Intel Core i9-13900K Gaming Benchmarks
Intel’s Core i9-13900K marks its first win in “A Plague Tale: Requiem.” The Ryzen 7 7800X3D isn’t far behind, trailing by 5% on average.
The Ryzen 7 7800X3D has fewer spikes in the frametime graph, resulting in a smoother gameplay experience.
In Assassins’ Creed Valhalla, the Ryzen 7 7800X3D takes the lead over the Intel Core i9-13900K, with much higher lows.
All recent Assassin’s Creed games exhibit the following stuttery behavior even on the fastest CPUs. It’s yet to be fixed.
Cyberpunk 2077 has gone from the worst-optimized to the most-optimized title within a year. The Core i9-13900K wins big, with a lead of 20%.
The frametime data indicates a bit of stuttering on the Ryzen side towards the end of the benchmark. The 13900K has similar but smaller spikes.
Dying Light 2 is a tie between the two processors. However, the Ryzen 7 7800X3D registers notably higher lows.
The frametime graph produces an extremely clean line for the 7800X3D with spikes that reflect the change in the scene.
F1 2022 favors the Ryzen 7 7800X3D with a paltry 6% lead over the 13900K. The latter also exhibits a fair bit of stuttering through the course of the benchmark.
The worse lows on the Core i9 are represented by the periodic spikes on the frametime data below:
Ghostwire Tokyo marks another win for AMD. However, the Core i9-13900K offers a smoother experience in comparison.
Both the CPUs face slight micro-stuttering, but the 7800X3D is more affected by it.
Hitman 3 is another big win for the Ryzen 7 7800X3D, with a lead of 75% over the 13900K.
Even the frametime graphs look much better for the X3D while the Core i9-13900K produces a bit of a mess.
Hogwarts Legacy is another game that runs exceptionally well on the 7800X3D. We’re again looking at a >70% lead over the Core i9-13900K, with notably smoother frametimes.
The frametime graph of the 7800X3D is interesting. It looks almost like there’s almost a cap (L3 cache serves) keeping the frametimes limited to 5ms. In comparison, the 13900K faces a fair number of spikes.
Shadow of the Tomb Raider favors the Ryzen 7 7800X3D, with a 49% lead over the Core i9-13900K. The lows don’t look any good either for the Core i9.
However, a look at the frametime graph reveals more consistent frame-pacing for the Intel part.
The Callisto Protocol is an AMD partner title, yet the Core i9-13900K manages a strong win with similar lows. The frametime graphs of the two CPUs are almost identical.
Tiny Tina’s Wonderlands is the final rasterized benchmark, and it also runs better on the Ryzen 7 7800X3D. The 13900K is a bit over 10% slower than the Ryzen with notably worse lows and a messy frametime graph.
Overall, that’s seven wins for the Ryzen 7 7800X3D and four for the Core i9-13900K in rasterization.
