Doom

The Intel Core i5-13400F paired with the AMD Radeon RX 7800 XT delivers frame rates in Doom that position this combination solidly within the upper tier of tested systems. With a combo rank of 615 out of 1681 tested configurations, this setup places itself in the 63rd percentile of all recorded pairings. This is a strong result for a 1080p and 1440p gaming focus, indicating that the hardware is well matched for the game's demands without being an outlier at the extreme high end.

How This Combo Ranks

The combination’s rank of 615 out of 1681 combos reflects a system that outperforms the majority of tested configurations while leaving headroom above the median. The data shows that this pairing is not near the top of the leaderboard, but its position is respectable for a mid-to-high-range setup. The GPU's percentile versus all GPUs is 76, which is notably higher than the CPU's percentile versus all CPUs at 82, though both are in the upper quartile. This suggests the graphics card is a slightly stronger contributor to the overall ranking than the processor.

When examining the individual components, the AMD Radeon RX 7800 XT sits within a tight cluster of rivals. Its average benchmark score of 32619 is only 0.2% above the AMD FirePro S9300 X2 and 0.4% below the NVIDIA P104-100. This indicates that in general compute tasks, the GPU is virtually interchangeable with these competitors. The CPU similarly shows a narrow margin over its nearest rivals, with the Intel Core i5-13400F's average score of 25236 sitting just 0.1% above the Intel Core i7-13620H and 0.5% below the AMD Ryzen 5 5600X3D. These small deltas suggest that the specific silicon choices matter less than the overall platform balance.

Settings Recommendations

Benchmark results across all measured resolutions show a consistent pattern where the "Low" preset delivers the highest average frame rates, followed by "Medium", "High", and finally "Ultra". At 1080p, the spread between settings is substantial: Low achieves 281.7 FPS, Medium drops to 247.2 FPS, High falls to 207.6 FPS, and Ultra bottoms out at 170.8 FPS. This represents a 39% reduction in frame rate from Low to Ultra at 1080p, which is a significant cost for the visual fidelity upgrade.

For the best experience balancing visual quality and performance, the data points to the "High" preset as the sweet spot. At 1440p, High delivers 135.1 FPS, which remains well above the 60 FPS threshold for smooth gameplay while offering substantially better visuals than Low or Medium. The Ultra preset at 1440p still achieves 112 FPS, making it viable for competitive play, but the diminishing returns between High and Ultra are apparent. At 4K, High drops to 75.1 FPS, which is still playable but approaches the edge of what many users consider acceptable for a fast-paced shooter. The measured data suggests that High provides the most consistent experience across all three resolutions without sacrificing the visual polish that makes Doom's environments engaging.

Resolution Scaling

The frame rate scaling from 1080p to 4K reveals important characteristics about which component is the bottleneck. At High settings, the system produces 207.6 FPS at 1080p, 135.1 FPS at 1440p, and 75.1 FPS at 4K. This represents a 35% drop from 1080p to 1440p, and a further 44% drop from 1440p to 4K. The total reduction from 1080p to 4K is 64%. Such a steep decline when moving to 4K strongly indicates the GPU is the limiting factor at higher resolutions.

The pattern holds across all settings. At Low, the system achieves 281.7 FPS at 1080p, 179.5 FPS at 1440p, and 98.2 FPS at 4K. At Ultra, the numbers are 170.8 FPS, 112 FPS, and 61 FPS respectively. The consistent scaling pattern suggests that the CPU has sufficient headroom to feed the GPU at lower resolutions, but the RX 7800 XT's rendering throughput becomes the constraint as pixel count increases. The fact that even at 1080p Low the system "only" reaches 281.7 FPS, rather than pushing toward 400 FPS, hints that the CPU does impose some upper bound, but this ceiling is high enough to avoid being the primary limitation in practical gaming scenarios.

FAQ

Q: How does this combo rank among all tested systems in Doom?
