The AMD Ryzen 7 7800X3D is one of the fastest gaming processors on the market. With a price tag of $449, the octa-core 3D V-Cache chip mangles its more expensive Intel rivals. The 7800X3D has a TDP of 120W and often draws a third as much power as the Core i9-13900K. This review compares the two heavyweights across thirteen popular titles and compiles the results.

AMD Ryzen 7 7800X3D Gaming Benchmarks
We tested all the games using the “Ultra” graphics quality at 720p native (without any upscaling techniques):
The Ryzen 7 7800X3D and Core i9-13900K split the spoils in the first four games. The former wins by a large margin in Cyberpunk 2077 with rasterization and ray-tracing, while the rest are a close call. The Crysis Remaster is an Intel favorite, leading the 7800X3D by 20% at the “Very High” RT preset.
The Ryzen 7 7800X3D absolutely dominates the Core i9-13900K in the second set of games. In Dying Light 2 and Ghostwire Tokyo, it maintains a hefty lead of 80% and 60%, respectively. Hitman 3 sees a massive gulf of over 160 FPS between the CPUs in rasterization, which gets reduced to 60 FPS with ray-tracing enabled.
In the last five, the Ryzen 7 7800X3D ekes out in three, leaving the Core i9-13900K with only four victories and nine defeats. This isn’t even close. The 7800X3D is clearly the better option, especially if you consider the lower price, power, and cheaper platform.
Thermals, Power, and Clocks
The Ryzen 7 7800X3D is one of the most energy-efficient CPUs on the market. It draws a mere 50-55W under load while the Core i9-13900K tops out at 199W. The X3D stays below 75C, averaging 73C in the most intensive scenarios. Meanwhile, the 13900K averages 83C with a peak of 97C. The former runs at a much lower clock (4900MHz vs. 5500MHz), showing that cache is most important in gaming workloads.
The Ryzen 7 7800X3D is the better chip, no matter how you look at it. It’s faster, draws less power, and runs 10C cooler. Pair it with a $100 A620 board, and you’ve got a capable gaming PC for just around $1,000.
