Rust

The Intel Core i3-12100F paired with the NVIDIA GeForce RTX 4070 delivers a strong Rust experience, but the data shows that 4K gaming is the only area where compromises are needed. In short, this PC is fully capable of running Rust at 1080p and 1440p with maximum settings, while 4K requires dropping to Medium settings to stay above the 60 FPS threshold. The measured results indicate a system that is heavily GPU-bound at higher resolutions, but the four-core i3-12100F still manages to keep up at 1080p, where frame rates exceed 200 FPS on Low settings.

Measured FPS Breakdown

The measured FPS data for Rust reveals a clear performance hierarchy across the three resolutions and four quality presets. At 1920x1080, the system is exceptionally fast, with the Low preset averaging 204.2 FPS. This drops to 151.7 FPS on Medium, 129.6 FPS on High, and 100.1 FPS on Ultra. Notably, even the most demanding 1080p preset, Ultra, maintains an average above 100 FPS, indicating substantial headroom for high-refresh-rate monitors.

Moving to 2560x1440, the performance remains strong but shows a more pronounced scaling penalty. The Low preset averages 156.4 FPS, which is a 23% reduction from the 1080p Low result. Medium follows at 101.6 FPS, High at 87.9 FPS, and Ultra at 69.7 FPS. The gap between Low and Ultra at this resolution is 86.7 FPS, which is a larger absolute difference than at 1080p, where the gap is 104.1 FPS. This suggests that the GPU is starting to become a more significant factor as pixel count increases.

At 3840x2160, the performance curve becomes much steeper, and the system clearly struggles with the highest presets. Low settings average 93.3 FPS, which is still playable but represents a 40% drop from 1080p Low. Medium averages 60.9 FPS, barely clearing the 60 FPS threshold. High settings drop to 54.4 FPS, and Ultra falls to 36.8 FPS. The difference between Low and Ultra at 4K is 56.5 FPS, showing that the RTX 4070's rendering load at this resolution is extreme.

The data also shows that the scaling between presets is not linear. At 1080p, going from Low to Medium costs 52.5 FPS, while from High to Ultra costs 29.5 FPS. At 1440p, the Low-to-Medium drop is 54.8 FPS, and the High-to-Ultra drop is 18.2 FPS. At 4K, the Low-to-Medium drop is 32.4 FPS, and the High-to-Ultra drop is 17.6 FPS. This suggests that the visual quality gains from higher presets become relatively cheaper at higher resolutions, but the baseline performance is much lower.

CPU and GPU Roles

The benchmark results indicate that the RTX 4070 is the primary performance driver at 4K, while the i3-12100F has enough single-thread strength to keep the system balanced at lower resolutions. Evidence for this comes from the scaling between 1080p and 1440p. At Low settings, the average FPS drops from 204.2 to 156.4, a 23% reduction. At Ultra settings, the drop is from 100.1 to 69.7, a 30% reduction. This larger relative drop at Ultra suggests that the GPU is working harder at higher presets, which is expected.

However, the CPU's role is visible in the 1080p results. The fact that Low settings at 1080p hit 204.2 FPS, while the RTX 4070 is capable of much higher frame rates in other games, points to the i3-12100F being a limiting factor at this resolution. The CPU's passmark single-thread score is 3444, and its 3dmark single-thread score is 893, which are respectable numbers for a quad-core part but not top-tier. The data shows that at 1080p Low, the system is likely CPU-bound, as the GPU could theoretically render more frames if the CPU could feed it faster.

At 1440p, the balance shifts more toward the GPU. The Ultra preset at 1440p (69.7 FPS) is 30% slower than at 1080p (100.1 FPS), which aligns with the 78% increase in pixel count. This indicates that the GPU is now the dominant bottleneck. At 4K, the GPU is overwhelmingly the limiting factor. The Ultra preset at 4K (36.8 FPS) is 63% slower than at 1440p, and the pixel count increases by 125% from 1440p to 4K. This disproportionate drop suggests that the RTX 4070's memory bandwidth (504.2 GB/s) and compute resources are being saturated.

The CPU's influence is most apparent in the low-setting results at 1080p. The i3-12100F's boost clock of 4.30 GHz and its 12 MB of shared L3 cache help it maintain high single-thread performance, which Rust relies on for game logic and physics. But the data shows that the CPU cannot push beyond 204.2 FPS at 1080p Low, while the GPU's measured passmark G3D score of 26927 indicates it has more headroom. For players targeting 144Hz or 240Hz at 1080p, this CPU will be the ceiling.

Best Settings per Resolution

For 1920x1080, the best settings are Ultra, which delivers an average of 100.1 FPS. This is the most demanding preset available, and it clears the 60 FPS threshold by a wide margin. Players can enable maximum quality without worrying about frame rate, as even the highest preset leaves 40 FPS of headroom above the playable threshold.

At 2560x1440, Ultra settings also provide the best experience, with an average of 69.7 FPS. This is above the 60 FPS threshold but with less margin than at 1080p. The data shows that High settings at 1440p (87.9 FPS) would offer more frame rate buffer, but Ultra remains playable and is the best choice for visual fidelity.

For 3840x2160, the best settings are Medium, which yields an average of 60.9 FPS. This is just barely above the 60 FPS threshold. High settings (54.4 FPS) fall below the playable mark, and Ultra (36.8 FPS) is far too demanding. The Low preset (93.3 FPS) is also playable, but Medium offers better visual quality while still maintaining that critical 60 FPS average.

The Verdict

This PC can run Rust successfully at all three tested resolutions, but with important caveats at 4K. At 1920x1080, all four presets (Low, Medium, High, Ultra) are playable, with the Ultra preset averaging 100.1 FPS. This means the system can handle any settings combination at 1080p without dropping below the playable threshold of 60 FPS.

At 2560x1440, the verdict is equally positive. All four presets are playable, with the Ultra preset averaging 69.7 FPS. Players can use maximum settings at 1440p and still maintain a frame rate that is 9.7 FPS above the threshold. The High preset (87.9 FPS) and Medium preset (101.6 FPS) offer even more headroom for those who prefer higher frame rates.

At 3840x2160, the verdict is more nuanced. Only Low (93.3 FPS) and Medium (60.9 FPS) are playable. High (54.4 FPS) and Ultra (36.8 FPS) fall short of the 60 FPS threshold. Therefore, at 4K, players must use Medium settings to get the best balance of visual quality and performance. The data clearly indicates that 4K Ultra is not achievable with this combination.

Overall, the system ranks 895th out of 3723 combinations tested for this game, placing it in the upper quartile of all tested hardware. The i3-12100F's 68th percentile ranking among all CPUs and the RTX 4070's 81st percentile among all GPUs confirm that this is a balanced, above-average pairing for Rust.

Similar Performance Alternatives

For the CPU, the Intel Core i3-12100F's nearest rivals in benchmark performance offer nearly identical results. The Intel Core 3 N355 has an average score of 13492, which is essentially the same as the i3-12100F's 13494, with a deltaPct of 0. This means swapping to the N355 would yield no measurable difference in CPU-bound scenarios. The Intel Core i5-9500 scores 13452, just 0.3% slower, while the Intel Core 5 120UL scores 13594, which is 0.7% faster. The Intel Core i7-1250U scores 13351, 1.1% slower. In Rust, where the CPU is critical for 1080p Low settings, any of these alternatives would behave similarly in terms of frame rates.

For the GPU, the NVIDIA GeForce RTX 4070's nearest rivals are also close in performance. The NVIDIA Tesla P4 has an average score of 37628, just 0.1% below the RTX 4070's 37648. The AMD Radeon RX Vega 56 scores 37507, 0.4% slower. The NVIDIA GeForce RTX 4080 Mobile scores 38135, which is 1.3% faster, and the AMD Radeon PRO W6400 scores 37157, 1.3% slower. In practical terms, these GPUs would produce nearly identical frame rates in Rust at all resolutions and presets. Players with any of these alternatives should expect the same 4K Medium (60.9 FPS) and 1440p Ultra (69.7 FPS) results.
