Rust

Can Intel Core i5-11400F + NVIDIA GeForce RTX 3080 run Rust? The recorded data says yes, with the answer depending heavily on resolution. At 1080p and 1440p, this combination delivers fully playable frame rates even at the highest preset. At 4K, the hardware is capable but requires a significant settings reduction to maintain smooth performance. The measurements show a system that is well-balanced for high-refresh 1440p gaming, while 4K users will need to make compromises in visual quality to stay above the 60 FPS threshold.

Measured FPS Breakdown

The database contains average FPS measurements for this specific CPU and GPU combination across three resolutions and four quality presets. No minimum or maximum frame time data was recorded, so the analysis relies on average performance only.

At 1920x1080, the results are uniformly strong. The Low preset delivers the highest raw throughput at 174.3 FPS average. Moving to Medium drops the average to 147 FPS, a reduction of 27.3 FPS from Low. The High preset records 124 FPS average, which is 23 FPS lower than Medium. The most demanding setting, Ultra, still holds an average of 92.3 FPS. The scaling from Low to Ultra shows a total drop of 82 FPS, indicating that the Ultra preset imposes a substantial load on the hardware, yet the final figure remains well within comfortable playable territory.

At 2560x1440, the same pattern emerges with lower absolute numbers. The Low preset averages 146 FPS. Medium follows at 100.6 FPS, a drop of 45.4 FPS. High comes in at 86 FPS average, and Ultra lands at 63.2 FPS. The transition from Medium to High is notable at 14.6 FPS, while the step from High to Ultra is a further 22.8 FPS. The difference between Low and Ultra at this resolution is 82.8 FPS, almost identical to the 1080p gap, but the Ultra result sits much closer to the 60 FPS playability floor.

At 3840x2160, the frame rates compress into a narrower band. The Low preset averages 89 FPS, which is the only setting at this resolution that clears the 60 FPS mark with headroom. Medium drops to 56.6 FPS, just below the playable threshold. High averages 50.5 FPS, and Ultra falls to 39.5 FPS. The scaling here is steep: Low to Medium costs 32.4 FPS, Medium to High costs 6.1 FPS, and High to Ultra costs 11 FPS. The total range from Low to Ultra at 4K is 49.5 FPS, showing that the Ultra preset at this resolution cuts performance nearly in half compared to Low.

Best Settings per Resolution

The playable threshold in the database is defined as 60 FPS average. The best settings are the most demanding preset that stays at or above that mark.

At 1920x1080, every recorded preset qualifies as playable. The best settings are therefore Ultra, which produces an average of 92.3 FPS. This leaves a 32.3 FPS margin over the 60 FPS floor, suggesting that even demanding scenes will likely hold above the threshold.

At 2560x1440, all four presets also remain playable. The Ultra preset averages 63.2 FPS, which is above the 60 FPS line but with only a 3.2 FPS margin. This is a tight buffer, and users who prefer a larger safety net might consider High at 86 FPS average. However, by the strict definition of the playable threshold, Ultra is the best setting for this resolution.

At 3840x2160, the situation changes dramatically. Only the Low preset stays above 60 FPS, averaging 89 FPS. Medium falls to 56.6 FPS, which is below the threshold. The best settings for 4K are therefore Low, with a 29 FPS margin over the playability floor. The jump from Low to Medium costs 32.4 FPS, which is a severe penalty for what is likely a modest visual improvement.

CPU and GPU Roles

The division of labor between the Intel Core i5-11400F and the NVIDIA GeForce RTX 3080 shifts as resolution increases. The data shows how the bottleneck moves from one component to the other.

At 1920x1080, the GPU is likely not the limiting factor. The frame rates are very high across all presets, with Low hitting 174.3 FPS and Ultra still at 92.3 FPS. The scaling from Low to Ultra at this resolution is 82 FPS, which indicates that the GPU has enough headroom to absorb the extra load of higher presets. The CPU, with its 6 cores and 12 threads, appears sufficient to feed the GPU at these frame rates, as even the heaviest preset does not cause a collapse.

At 2560x1440, the GPU begins to take a more prominent role. The frame rates are lower across the board compared to 1080p, with Low at 146 FPS and Ultra at 63.2 FPS. The resolution increase from 1080p to 1440p reduces performance by 28.3 FPS at Low, 46.4 FPS at Medium, 38 FPS at High, and 29.1 FPS at Ultra. The larger absolute drops at Medium and High suggest that the GPU is working harder to fill the extra pixels, while the CPU side remains relatively constant.

At 3840x2160, the GPU is clearly the dominant factor. The frame rates are dramatically lower, with Ultra at 39.5 FPS and Medium at 56.6 FPS. The resolution increase from 1440p to 4K costs 57 FPS at Low, 44 FPS at Medium, 35.5 FPS at High, and 23.7 FPS at Ultra. The fact that the Low preset at 4K still produces 89 FPS indicates that the GPU can handle the pixel count when the shading load is light. The CPU is unlikely to be a bottleneck at this resolution, as the frame rates are low enough that even a modest processor could keep up.

The preset scaling also reveals the GPU's role. At 1080p, the difference between Low and Ultra is 82 FPS, while at 4K it is 49.5 FPS. This compression at higher resolutions is typical of a GPU-bound scenario, where the absolute frame rate ceiling is lower and the relative cost of each preset becomes larger in percentage terms. The data indicates that users with a 1080p or 1440p display will be limited by the CPU in some low-preset scenarios, while 4K users will see the GPU as the clear performance governor.

How This Combo Ranks

In the database of tested hardware combinations for Rust, this pairing holds a rank of 1144 out of 3723 total combos. This places it in the top 30.7 percent of all tested systems, which is a solid position for a mid-generation CPU paired with a high-end GPU.

The rank reflects the system's ability to handle Rust at high settings and high resolutions. The GPU's percentile standing of 68 against all GPUs suggests that the RTX 3080 is a strong performer, while the CPU's percentile of 71 against all CPUs indicates a balanced pairing. The combination rank of 1144 suggests that while the GPU is powerful, it is not paired with the absolute fastest processors, which would push the combo higher in the rankings.

The measured frame rates support this ranking. At 1440p Ultra, the system achieves 63.2 FPS, which is playable but not exceptionally high. A system with a faster CPU might push that number higher, but the current pairing is sufficient for a smooth experience. At 1080p, the frame rates are high enough that the ranking might be held back by the CPU in low-preset scenarios, where the GPU is not fully utilized.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-11400F in the database are all within a narrow performance band. The AMD EPYC 7H12 has an average score that is 0.3 percent higher, while the Intel Core i5-12450H is 0.4 percent lower. The AMD Ryzen 3 PRO 8300G is 0.6 percent lower, and the Intel Core Ultra 7 164U is 0.6 percent higher. These deltas are all under one percent, meaning that swapping the i5-11400F for any of these CPUs would result in nearly identical frame rates in Rust, assuming the GPU remains the same.

On the GPU side, the nearest rivals to the RTX 3080 are similarly close. The NVIDIA P106-100 has an average score that is 0.3 percent lower, while the AMD Radeon Pro Vega 16 is also 0.3 percent lower. The AMD Radeon RX 6600M is 0.4 percent lower, and the AMD Radeon R9 M290X is 0.4 percent lower. These deltas are negligible, so a user with any of these GPUs paired with the i5-11400F would see essentially the same performance as the RTX 3080 in this game.

For practical purposes, the data suggests that the i5-11400F and RTX 3080 combination is at a performance plateau. Moving to any of the listed rival CPUs or GPUs would not meaningfully change the frame rates in Rust. The system's rank of 1144 out of 3723 is therefore representative of a broad cluster of hardware that delivers similar gameplay experiences.
