Rust

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 3080 delivers a robust performance profile in Rust, with benchmark data showing that this combination is well-suited for high-refresh-rate gaming at mainstream resolutions while remaining capable at 4K with adjusted settings. The measured FPS data reveals a clear scaling pattern where the GPU becomes the dominant factor as resolution increases, while the CPU's 6-core/12-thread configuration provides sufficient headroom for the game's simulation-heavy workload.

Measured FPS Breakdown

At 1920x1080, this combo demonstrates substantial headroom across all presets. The Low preset averages 205 FPS, which is the highest recorded figure in the entire dataset and indicates that the system is largely CPU-bound at this resolution with lower graphical loads. Moving up to Medium settings, the average drops to 145 FPS with a minimum of 123 FPS and a maximum of 166 FPS, showing consistent frame delivery that stays well above any refresh-rate concerns. High settings yield 122 FPS average, while the most demanding Ultra preset still maintains a strong 93 FPS average, proving that even at maximum graphical fidelity, the system never approaches the 60 FPS threshold from above.

Stepping up to 2560x1440, the performance remains excellent but begins to show the GPU's workload increasing. The Low preset delivers 148 FPS average, still comfortably in high-refresh territory. Medium settings produce 100 FPS average with a minimum of 85 FPS and maximum of 115 FPS, indicating good frame pacing with no severe drops. High settings average 84 FPS, while Ultra drops to 64 FPS average. This 64 FPS figure is notable because it sits just above the 60 FPS playable threshold, meaning that even at the highest preset, the system barely maintains playability at 1440p.

At 3840x2160, the GPU workload becomes much more demanding. The Low preset is the only configuration that clears the 60 FPS threshold comfortably, averaging 88 FPS. Medium settings average 59 FPS with a minimum of 50 FPS and maximum of 68 FPS, placing it just below the playable threshold on average but with some frames exceeding 60 FPS. High settings drop to 50 FPS average, while Ultra falls to 38 FPS average. The gap between Low (88 FPS) and Ultra (38 FPS) at 4K represents a 50 FPS swing, demonstrating how heavily the higher presets impact the RTX 3080's rendering load.

How This Combo Ranks

The benchmark database ranks this specific CPU-GPU combination at position 1037 out of 3723 tested combos for Rust. This places the system in the top 27.8% of all configurations tested, which is a strong showing given the wide range of hardware combinations in the database. The percentile ranking reflects that while this is not an absolute top-tier configuration, it sits well above the median and should handle the game comfortably at most resolutions.

The CPU itself holds a 73rd percentile ranking among all CPUs in the database, while the GPU sits at the 68th percentile among all GPUs. These individual rankings suggest that the system's overall performance is well-balanced, with neither component dramatically outperforming the other relative to their respective pools. The combo's rank in-game at 1037 out of 3723 aligns with these component-level percentiles, indicating that Rust's performance scaling with this hardware follows expected patterns without unusual bottlenecks or inefficiencies.

Similar Performance Alternatives

Looking at the CPU's nearest rivals, the AMD Ryzen 5 7535HS shows an average score of 19047, which is effectively identical to the i5-12400F's 19039 average (0% delta). This suggests that systems built around the Ryzen 5 7535HS would deliver nearly indistinguishable CPU performance in Rust. The Intel Core 3 201E scores 19056 (-0.1% delta), also essentially matching the i5-12400F's performance. The Intel Core i5-1335U scores 18982 (0.3% delta), placing it slightly below the i5-12400F but within a negligible margin. The AMD EPYC 7773X scores 18979 (0.3% delta), similarly close. These rivals indicate that any of these CPUs would produce very similar frame rates in CPU-bound scenarios, though the i5-12400F's desktop-oriented architecture with 6 cores and 12 threads may behave differently in sustained workloads compared to the mobile-oriented chips.

On the GPU side, the nearest rivals to the RTX 3080 are somewhat unexpected. The NVIDIA P106-100 scores 23249 (-0.3% delta), the AMD Radeon Pro Vega 16 scores 23250 (-0.3% delta), the AMD Radeon RX 6600M scores 23273 (-0.4% delta), and the AMD Radeon R9 M290X scores 23276 (-0.4% delta). These delta values are all within half a percent of the RTX 3080's 23172 average score, yet these are dramatically different GPUs in terms of architecture and intended use cases. The P106-100 is a mining-oriented card, the Pro Vega 16 is a professional mobile GPU, and the R9 M290X is an older mobile part. This underscores that average benchmark scores alone do not capture real-world gaming performance differences, as the RTX 3080's 10 GB of GDDR6X memory and 760.3 GB/s bandwidth would provide significantly better texture throughput in Rust than these rivals despite similar synthetic scores.

The Verdict

Benchmark results indicate that this system can run Rust effectively across all tested resolutions, but with important caveats at 4K. At 1920x1080, all four presets clear the 60 FPS threshold with substantial margin, making any settings configuration viable for smooth gameplay. The Ultra preset averages 93 FPS, which is 55% above the 60 FPS playable threshold, providing a comfortable buffer for demanding scenes.

At 2560x1440, the verdict is equally positive. All four presets maintain averages above 60 FPS, with Ultra at 64 FPS being the only preset that approaches the threshold. This means that at 1440p, players can use the highest settings while still maintaining playable frame rates, though the 64 FPS average leaves less headroom for frame drops during intense moments.

At 3840x2160, the verdict becomes more restrictive. Only the Low preset clears the 60 FPS threshold, averaging 88 FPS. Medium settings average 59 FPS, which is just below the playable threshold, meaning it would likely produce noticeable stutter or frame pacing issues despite occasionally exceeding 60 FPS. High and Ultra settings fall well below the threshold at 50 FPS and 38 FPS respectively. Therefore, at 4K, the system should be configured to Low settings for consistent playability, though users with adaptive sync displays might find Medium acceptable given its 50-68 FPS range.

Best Settings per Resolution

At 3840x2160, the best settings configuration is Low, which achieves an average of 88 FPS. This is the only preset at 4K that maintains an average above 60 FPS, making it the sole recommended option for playable performance. While the Medium preset averages 59 FPS with a minimum of 50 FPS and maximum of 68 FPS, its average falls below the threshold, so Low is the safest choice.

At 2560x1440, the best settings configuration is Ultra, which averages 64 FPS. This preset provides the highest visual quality while still maintaining an average above the 60 FPS playable threshold. The margin is relatively slim, but the data confirms that Ultra is playable at this resolution.

At 1920x1080, the best settings configuration is also Ultra, averaging 93 FPS. This provides a much larger margin above the threshold compared to 1440p, giving players confidence that even demanding scenes will maintain smooth frame rates.

CPU and GPU Roles

The measured FPS data reveals a clear division of labor between the CPU and GPU across resolutions. At 1920x1080, the system achieves 205 FPS on Low settings, which is the highest average in the dataset. This high frame rate at a low graphical preset indicates that the CPU is capable of feeding the GPU with enough draw calls and simulation data to maintain very high frame rates, and the GPU is not yet saturated. The difference between Low (205 FPS) and Ultra (93 FPS) at 1080p represents a 112 FPS gap, driven entirely by GPU rendering workload as the CPU has ample headroom at this resolution.

Moving to 2560x1440, the Low preset still achieves 148 FPS, showing that the CPU remains capable of high frame rates even with the increased resolution. However, the gap between Low (148 FPS) and Ultra (64 FPS) widens to 84 FPS, indicating the GPU is becoming more of a limiting factor. The Ultra preset at 1440p drops to 64 FPS, which is nearly identical to the 4K Medium preset's 59 FPS, suggesting that the GPU's rendering capabilities are the primary constraint at higher resolutions and settings.

At 3840x2160, the GPU's dominance becomes unmistakable. The Low preset drops to 88 FPS from 148 FPS at 1440p Low, showing that even the least demanding preset is heavily impacted by the resolution increase. The difference between 4K Low (88 FPS) and 4K Ultra (38 FPS) represents a 50 FPS range, and the fact that 4K Low barely exceeds 1080p Ultra's 93 FPS demonstrates that the RTX 3080's rendering throughput is the decisive factor at this resolution. The CPU's influence diminishes as resolution increases, with the i5-12400F providing consistent simulation performance while the GPU's pixel and texture processing becomes the bottleneck.
