Doom

Benchmark data for Doom on the AMD Ryzen 9 7900X and NVIDIA GeForce RTX 4090 shows a high-performance pairing across every tested resolution and settings level. The measured FPS table includes 1920x1080, 2560x1440, and 3840x2160 with Low, Medium, High, and Ultra settings, and the combination is ranked 22nd out of 1681 tested CPU/GPU pairs.

Resolution Scaling — how FPS drops from 1080p to 4K and what it says about the limiting component

The resolution scaling pattern is consistent: for every settings level, average FPS falls when resolution moves from 1920x1080 to 2560x1440 to 3840x2160. At Low, the system produces 441.2 fps at 1920x1080, 290 fps at 2560x1440, and 155.5 fps at 3840x2160. At Medium, the values are 390.1, 254.1, and 134.8 fps. High drops from 329.3 fps to 209.9 fps to 113.6 fps, and Ultra drops from 266.5 fps to 173.9 fps to 96.8 fps.

This ordering shows that pixel count is a major factor in the measured results. At every resolution, the Low setting also produces the highest average, followed by Medium, High, and Ultra. That means settings workload changes frame rates just as clearly as resolution changes.

The 1920x1080 Low result of 441.2 fps is particularly instructive. It shows the processor and memory subsystem can support very high frame delivery when the per-pixel load on the GPU is low. The 1920x1080 Ultra result of 266.5 fps remains high, which suggests the CPU is not preventing strong performance even under higher settings. As resolution increases to 3840x2160, the GPU has to process far more pixels, and the lower averages at 4K indicate the graphics card becomes the more heavily loaded component. The 3840x2160 Ultra average of 96.8 fps is still high, but the gap between 1920x1080 and 3840x2160 at every setting is substantial, pointing toward GPU-limited scaling at higher resolutions.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4090 dominates the graphics side of this combination. It has 24 GB of GDDR6X memory, a 384-bit memory bus, and 1.01 TB/s memory bandwidth. The base clock is 2235 MHz and the boost clock is 2520 MHz. These figures describe a large graphics memory interface and high operating clock range.

The Doom results show the GPU handling all three tested resolutions without falling below a high average. At 3840x2160 Ultra, the average is 96.8 fps. At 3840x2160 Low, it climbs to 155.5 fps. At 2560x1440, the range runs from 173.9 fps at Ultra to 290 fps at Low. At 1920x1080, the range is 266.5 fps at Ultra to 441.2 fps at Low. This pattern is consistent with the GPU absorbing additional rendering work as settings and resolution increase.

The general benchmark profile also places the GPU near the top of its database. The RTX 4090 has an average benchmark score of 66473 and sits in the 91st percentile versus all GPUs. Its nearest rivals in the average-score comparison are the NVIDIA Tesla T4 with an average score of 66733 and a deltaPct of -0.4, the NVIDIA Tesla P40 with an average score of 66127 and a deltaPct of 0.5, the AMD Radeon Pro Vega 56 with an average score of 67097 and a deltaPct of -0.9, and the NVIDIA Quadro P6000 with an average score of 67320 and a deltaPct of -1.3.

How This Combo Ranks

The combo rank field places this system at rank 22 out of 1681 tested combos in Doom. That is a high placement in the measured FPS database. The individual component percentiles are also strong: the Ryzen 9 7900X is in the 93rd percentile versus all CPUs, and the RTX 4090 is in the 91st percentile versus all GPUs. The in-game rank of 22 is therefore consistent with the overall benchmark standing of both parts.

The rank data does not list the names of the 21 combinations ranked above this one, so direct rival comparisons within Doom are not available from the fact pack. What can be stated from the data is the final position: this 7900X + RTX 4090 setup is the 22nd-fastest among 1681 recorded combinations for this game.

CPU Role — cores, clocks, and how they relate to this game's results

The AMD Ryzen 9 7900X contributes 12 cores and 24 threads to the system. Its base clock is 4.70 GHz and its boost clock is 5.60 GHz. It uses the Zen 4 Raphael architecture, supports DDR5 memory, and has a dual-channel memory bus with 83.2 GB/s bandwidth. The cache layout includes 64 MB of shared L3 cache.

The CPU benchmark data shows strong multithreaded and single-threaded performance. In Cinebench R23, the CPU scores 43695 in multi-core and 6168 in single-core. In PassMark multithread testing, it scores 51406, and in single-thread testing it scores 4238. These results reflect both high thread throughput and high per-thread speed.

In Doom, the CPU’s role is most visible at 1920x1080, where frame rates are extremely high even on the Low preset. The 1920x1080 Low result of 441.2 fps, 2560x1440 Low result of 290 fps, and 3840x2160 Low result of 155.5 fps form a clear scaling chain. The ability to reach 441.2 fps at 1920x1080 suggests the CPU can keep pace when the GPU has relatively light per-pixel work. The 1920x1080 Ultra result of 266.5 fps also remains high, showing the CPU continues to deliver solid frame rates under higher settings.

The CPU’s nearest rivals in average benchmark score are the Intel Core Ultra 5 235 with an average score of 50598 and a deltaPct of -0.1, the AMD Ryzen 9 5900XT with an average score of 50738 and a deltaPct of -0.4, the Intel Core i7-13850HX with an average score of 50827 and a deltaPct of -0.5, and the Intel Core i9-13980HX with an average score of 50944 and a deltaPct of -0.8. The Ryzen 9 7900X’s own average benchmark score is 50556.

Measured FPS Breakdown — resolution by resolution, settings by settings, exact numbers

The measured FPS data is organized by resolution and settings. All values are reported as average FPS; minimum and maximum FPS fields are not present in the data. The measured flag is true, meaning these are measured results rather than estimates.
