AMD Ryzen 7 7800X3D vs Intel Core i9-13900K: 12 Gaming Benchmarks, Power Efficiency, Temps

The launch of the Ryzen 7 7800X3D puts AMD firmly in control of the gaming CPU market. The affordable price point, power draw, and platform pricing make it a better option than any Intel chip on the market. In this post, we’ll test the 7800X3D across 13 games, with and without ray-tracing, to see where it stands compared to the Core i9-13900K.

Test Bench

  • Motherboard: ASUS ROG X670E Hero/Z790 Hero.
  • Memory: 16GB x2 DDR5 6000MT/s CL38.
  • Cooler: Lian Li Galahad x360.
  • GPU: GeForce RTX 4090 FE,
  • PSU: Corsair HX1000i.

Ryzen 7 7800X3D vs Core i9-13900K: 720p Gaming Benchmarks

In gaming, GPUs scale across resolutions and the graphics settings used. CPUs, however, are only affected by the polygon counts (rendering quality) and not the rendering resolution. Therefore, we tested the two CPUs at 720p to reduce any possible GPU bottlenecks. The mighty RTX 4090 should have no difficulty rendering even the most taxing games at 720p and it’ll be held back by the CPU (read previous lines).

The Core i9-13900K snags a win in “A Plague Tale” both with and without ray-tracing. It’s marginally faster than the Ryzen 7 7800X3D with similar lows. The tables get turned in Assassins’ Creed Valhalla as the 7800X3D edges past the 13900K in Ubisoft’s latest title.

Crysis Remastered has always preferred Intel chips and that hasn’t changed even with the release of the Ryzen 2nd Gen V-Cache processors. The Core i9-13900K is 20% faster than the 7800X3D in Crytek’s ray-traced game.

Cyberpunk 2077 is faster on the Ryzen 7 7800X3D, leading the Core i9-13900K by 33% and 17% with and without ray-tracing, respectively. Dying Light 2 marks an even stronger win for the 7800X3D with a lead of 80% over the 13900K with ray-tracing turned on.

F1 2022 is the third consecutive title in our list to favor the Ryzen 7 7800X3D, beating the i9-13900K by 15% and 8% with and without ray-tracing, respectively.

Hitman 3 is a particularly CPU-intensive game, and the 7800X3D takes full advantage of that. It crushes the Core i9 by a massive margin of 70%. With ray-tracing thrown into the mix, the delta dwindles to 42%.

Hogwarts Legacy is yet another game that runs much better on the Ryzen 7 7800X3D. The AMD chip maintains a lead of over 2x at 720p ultra which shrinks to 39% with ray-tracing on.
