Rust

This analysis covers the Intel Core i5-12400 paired with the NVIDIA GeForce RTX 5090 D for Rust, a survival game released on 2018-02-07. Measured frame rates across three resolutions and four settings presets show that the combination remains above the 60 FPS playable threshold at every tested configuration, with the Ultra preset averaging 61 FPS at 3840x2160, 103 FPS at 2560x1440, and 149 FPS at 1920x1080.

Similar Performance Alternatives

The i5-12400 posts an average benchmark score of 18683, placing it at the 72nd percentile among all CPUs. Its nearest rivals are extremely close in aggregate performance. The AMD EPYC 7643 scores 18697, which is 0.1% higher than the i5-12400. The Intel Core i7-1355U scores 18730, 0.3% higher. The AMD Ryzen AI 5 330 scores 18811, 0.7% higher. On the other side, the Intel Core i3-14100F scores 18519, which is 0.9% lower. In CPU-bound scenes, any of these processors would produce nearly identical frame pacing in Rust, because the differences are all under one percent.

The GPU side shows a similar pattern of tightly grouped rivals. The RTX 5090 D averages 77712, sitting at the 92nd percentile among all GPUs. The AMD Radeon RX 6650M XT scores 76904, which is 1.1% lower than the RTX 5090 D. The AMD Radeon RX 6850M XT scores 78940, 1.6% higher. The NVIDIA Tesla P100 PCIe 12 GB scores 79396, 2.1% higher, and the NVIDIA Tesla P100 PCIe 16 GB scores 79605, 2.4% higher. Thus, swapping to any of those GPUs would keep Rust performance within a few percent of this combo, assuming the CPU remains the same.

Because both the CPU and GPU have nearest rivals within roughly two and a half percent, the practical gaming experience with those alternatives would be very similar to what the i5-12400 and RTX 5090 D deliver. The measured FPS in Rust would shift only slightly, and the playable settings at each resolution would likely remain the same.

Best Settings per Resolution

At every resolution, the Ultra preset is the most demanding setting tested, and it stays at or above 60 FPS. Therefore, the best settings are Ultra at all three resolutions.

At 3840x2160, Ultra averages 61 FPS. That is just one frame above the 60 FPS playable threshold, but it clears it. At 2560x1440, Ultra averages 103 FPS, providing a comfortable margin. At 1920x1080, Ultra averages 149 FPS, which is far above the threshold. Since the Ultra preset is the highest available in this test and it remains playable everywhere, no lower preset is needed to reach playability.

The data also shows that lower presets offer much higher frame rates. For example, Low at 4K reaches 141 FPS, Low at 1440p reaches 179 FPS, and Low at 1080p reaches 203 FPS. But the question of best settings is about the most demanding preset that still clears 60 FPS, and that is Ultra at all three resolutions.

CPU and GPU Roles

Resolution scaling reveals where each component becomes the limiting factor. At 1920x1080, the Low preset averages 203 FPS and the Ultra preset averages 149 FPS. At 2560x1440, Low averages 179 FPS and Ultra averages 103 FPS. At 3840x2160, Low averages 141 FPS and Ultra averages 61 FPS.

The pattern shows that raising resolution costs more FPS when settings are high. The Low preset falls from 203 FPS at 1080p to 141 FPS at 4K, while the Ultra preset falls from 149 FPS at 1080p to 61 FPS at 4K. The gap between Low and Ultra widens as resolution increases, which indicates that the GPU's workload grows disproportionately with pixel count when the preset is demanding.

At 1080p, the Ultra preset still delivers 149 FPS, which is well above the 60 FPS threshold. This suggests that at lower resolutions the CPU is able to feed the GPU fast enough, and the frame rate is not tightly constrained by the GPU. At 4K, however, the Ultra preset lands at 61 FPS, very close to the playable threshold. That indicates the GPU is now the dominant constraint, because the higher resolution and heavier settings push the GPU much harder.

The Medium preset provides another view of this scaling. It averages 174 FPS at 1080p, 154 FPS at 1440p, and 95 FPS at 4K. The drop from 1440p to 4K is much steeper than the drop from 1080p to 1440p, which is consistent with a GPU that becomes increasingly loaded as resolution rises. In short, the CPU matters more at lower resolutions where frame rates are high, while the GPU matters more at higher resolutions and higher presets.

How This Combo Ranks

In the database, this specific CPU and GPU combination ranks 133 out of 3723 tested combos for Rust. That places it in the upper portion of all systems tested. The CPU sits at the 72nd percentile among all CPUs, while the GPU sits at the 92nd percentile among all GPUs. The measured FPS data is marked as measured, not estimated, which means the frame rates come from actual testing rather than projection.

The rank reflects the combined capability of the i5-12400 and the RTX 5090 D. The GPU is particularly strong relative to its peers, and the CPU is above average as well. The combination produces playable frame rates at all tested resolutions and presets, which is consistent with a high ranking. The fact that the Ultra preset at 4K still averages 61 FPS shows that this system is near the top end of what is needed for smooth gameplay in Rust.

The Verdict

The data indicates that this PC can run Rust at every resolution and preset tested. At 3840x2160, Ultra averages 61 FPS, which clears the 60 FPS playable threshold. At 2560x1440, Ultra averages 103 FPS, and at 1920x1080, Ultra averages 149 FPS. All three resolutions are playable on the highest settings.

For users who prefer higher frame rates, lower presets provide even more headroom. The Low preset yields 141 FPS at 4K, 179 FPS at 1440p, and 203 FPS at 1080p. The Medium preset stays above 95 FPS at 4K and above 154 FPS at 1440p. Overall, the i5-12400 and RTX 5090 D combination delivers a smooth experience across the board, with the only near-threshold result being 4K Ultra at 61 FPS.
