Doom

The AMD Ryzen 9 7900X paired with the NVIDIA GeForce RTX 4080 is an exceptionally powerful combination for Doom, delivering frame rates that far exceed the 60 FPS playability threshold at every tested resolution and preset. The benchmark data shows this system is not merely capable of running the game; it dominates it, with the least demanding settings producing over 400 FPS at 1080p and even the most punishing Ultra preset at 4K maintaining a smooth 85 FPS average. This is a textbook example of a high-end setup where the user can prioritize visual fidelity without compromising performance.

Best Settings per Resolution

At 1920x1080, the Ultra preset delivers an average of 241 FPS. This is the most demanding graphics configuration available in the game, and the data confirms it is not a bottleneck for this hardware. The performance headroom is enormous, with the High preset reaching 295 FPS and the Low preset hitting 401 FPS, making this resolution entirely GPU-bound at the highest settings.

Moving to 2560x1440, the system continues to excel. The Ultra preset, which is the most visually demanding option, maintains an average of 156 FPS. This is more than double the 60 FPS playable threshold, ensuring a fluid experience even in chaotic firefights. The scaling from 1080p to 1440p shows a performance drop of 85 FPS at Ultra, but the absolute numbers remain exceptionally high.

At 3840x2160, the story remains one of overwhelming capability. The Ultra preset is still the best setting, producing an average of 85 FPS. This is the only resolution where the frame rate dips below the triple digits, but it is still comfortably above the 60 FPS standard. The data indicates that the GPU's 16 GB of memory and 716.8 GB/s bandwidth are sufficient to handle 4K textures without issue, as even the most demanding settings stay well within playable territory. The Medium preset offers a small boost to 123 FPS, but the visual gains from Ultra are worth the 38 FPS difference for most users.

CPU and GPU Roles

The benchmark results across different resolutions and presets reveal a clear shift in system bottleneck behavior. At 1920x1080, the performance difference between presets is stark: the Low preset averages 401 FPS while Ultra averages 241 FPS. This 160 FPS gap indicates that the graphics workload is the primary variable, but the CPU’s 12 cores and 24 threads, based on its Zen 4 architecture, are more than capable of feeding the GPU at these high frame rates. The Ryzen 9 7900X’s strong single-thread performance, evidenced by a 3DMark single-thread score of 1093, prevents it from becoming a limiting factor even at the lowest settings where the GPU has less work to do.

At 2560x1440, the gap between presets narrows slightly (260 FPS Low vs 156 FPS Ultra), showing the GPU is beginning to take on a more significant role. However, the CPU still has ample headroom, as the average frame rates remain very high across all settings. The 226 FPS average at Medium, with a minimum of 192 FPS, demonstrates that the processor can maintain high throughput without stuttering, even when the GPU is working harder.

At 3840x2160, the GPU becomes the definitive bottleneck. The difference between Low (141 FPS) and Ultra (85 FPS) is 56 FPS, but the overall frame rates are lower than at other resolutions. This is expected, as the RTX 4080’s 48.74 TFLOPS of FP32 performance is being taxed by the increased pixel count. The CPU’s role diminishes further, as the frame rates are capped by the GPU’s rendering capabilities rather than the processor’s ability to issue draw calls. The data suggests that the Ryzen 9 7900X is never a limiting factor in this game; it provides a stable platform that allows the RTX 4080 to perform at its full potential across all resolutions.

The Verdict

This PC can absolutely run Doom, and it does so with remarkable ease. The verdict data is unambiguous: at every resolution from 1920x1080 to 3840x2160, all four settings (Low, Medium, High, and Ultra) are classified as playable. The best settings for each resolution are the Ultra presets, which provide the highest visual quality while still maintaining frame rates far above the 60 FPS target. At 1080p, the Ultra preset averages 241 FPS; at 1440p, it averages 156 FPS; and at 4K, it averages 85 FPS. The system not only clears the playable threshold but does so with a massive margin, making it suitable for high-refresh-rate monitors at 1080p and 1440p and for a smooth 4K experience. The Ryzen 9 7900X and RTX 4080 combination is a top-tier performer for this title, with no configuration in the test data presenting a challenge. The only consideration is that the 4K Ultra setting, while playable at 85 FPS, leaves less headroom for potential frame rate dips in extremely intense scenes, but the measured data does not indicate any such issues.
