Rust

The data shows that the Intel Core i5-12400F paired with the AMD Radeon RX 6800 XT delivers a highly capable Rust experience, but with a clear ceiling at 4K. At 1080p and 1440p, this combo clears the 60 FPS threshold at every preset, including Ultra, while 4K requires dropping to Low settings to maintain smooth gameplay. The combination of a mid-range 12th-gen CPU with a high-end RDNA 2 GPU proves to be well-balanced for Rust, with the GPU becoming the primary limiting factor only at 3840x2160.

Measured FPS Breakdown

The measured FPS data for this combo reveals distinct performance tiers across resolutions and settings. At 1920x1080, the results are uniformly strong. Low settings produce an average of 205.3 FPS, which is the highest figure recorded for this combo in any configuration. Moving up to Medium drops the average to 140.7 FPS, a substantial but expected reduction of roughly 31%. High settings yield 117.8 FPS on average, while Ultra — the most demanding preset — still maintains an average of 89.9 FPS. None of these 1080p results approach the playability floor of 60 FPS, leaving significant headroom even at the highest visual quality.

Stepping up to 2560x1440, the performance remains strong but shows the expected scaling penalty. Low settings average 146.3 FPS, which is about 29% lower than the equivalent 1080p result. Medium settings deliver 93.7 FPS, a drop from 140.7 FPS at 1080p. High settings average 82.3 FPS, while Ultra sits at 64.2 FPS. The Ultra figure is particularly notable: it clears the 60 FPS threshold by only 4.2 FPS, indicating that this is the edge of comfortable playability at 1440p with maximum visuals. The gap between Medium and High at 1440p is 11.4 FPS, while the gap between High and Ultra is 18.1 FPS, showing that the Ultra preset imposes a disproportionately larger cost.

At 3840x2160, the picture changes dramatically. Low settings are the only playable option, averaging 86.7 FPS. Medium settings fall to 59.6 FPS — just shy of the 60 FPS target — and High drops to 47.9 FPS. Ultra is the weakest result in the entire dataset, averaging only 34.7 FPS. The scaling from 1440p to 4K is severe: Medium falls from 93.7 FPS to 59.6 FPS (a 36% reduction), and High falls from 82.3 FPS to 47.9 FPS (a 42% reduction). This indicates that the RX 6800 XT's 16 GB of GDDR6 memory and 512.0 GB/s bandwidth are insufficient to maintain fluid frame rates at 4K with higher presets in Rust.

Best Settings per Resolution

For each resolution, the most demanding preset that maintains an average of at least 60 FPS is as follows. At 1920x1080, Ultra is the best playable setting, delivering an average of 89.9 FPS. This means the full visual experience is available at 1080p with ample margin above the playability threshold. At 2560x1440, Ultra also qualifies as the best playable setting, but with a much tighter margin: the average is 64.2 FPS, which is only 4.2 FPS above the 60 FPS floor. Players seeking a safety buffer at 1440p could drop to High, which averages 82.3 FPS, but the data confirms that Ultra is technically playable. At 3840x2160, the best playable setting is Low, with an average of 86.7 FPS. Medium at 4K falls short at 59.6 FPS, so it cannot be recommended for sustained 60 FPS gameplay.

Q: Is the RX 6800 XT the limiting factor at 4K?

A: The data suggests yes. At 3840x2160, even Medium settings fail to hit 60 FPS (59.6 FPS average), while dropping to Low yields 86.7 FPS. The GPU's performance scaling at 4K is steep, indicating a rendering bottleneck rather than a CPU limitation.

Q: What is the highest average FPS this combo achieves in Rust?

A: The highest recorded average is 205.3 FPS, achieved at 1920x1080 with Low settings.

Q: Does this combo ever drop below 60 FPS at 1440p?

A: No. All four presets at 2560x1440 — Low, Medium, High, and Ultra — average above 60 FPS. The lowest of these is Ultra at 64.2 FPS.

The Verdict

This PC can absolutely run Rust, and the data shows it handles the game with ease at mainstream resolutions. The verdict by resolution is clear. At 1920x1080, every preset is playable, with Ultra averaging 89.9 FPS. This is the sweet spot for this combo: maximum visual quality with substantial performance to spare. At 2560x1440, all presets also clear the 60 FPS bar, but Ultra is the only one that sits close to the line at 64.2 FPS. For a more stable experience at 1440p, High at 82.3 FPS is the safer recommendation. At 3840x2160, the situation is more restrictive. Only Low settings are playable, with an average of 86.7 FPS. Medium misses the target by a hair at 59.6 FPS, and High and Ultra fall further behind at 47.9 FPS and 34.7 FPS respectively. Therefore, this combo is best suited for 1080p and 1440p gaming, where it delivers a fully playable experience across all settings. 4K gaming is possible only with significant visual compromises.

CPU and GPU Roles

The performance scaling across resolutions and presets reveals how the CPU and GPU divide responsibility in Rust. At 1920x1080, the CPU's influence is most pronounced. The jump from Low (205.3 FPS) to Medium (140.7 FPS) is a 64.6 FPS drop, and the jump from High (117.8 FPS) to Ultra (89.9 FPS) is a 27.9 FPS drop. These large deltas at 1080p indicate that the i5-12400F is capable of feeding the RX 6800 XT enough data to reach very high frame rates, but the GPU's workload grows quickly as settings increase. The fact that Low at 1080p exceeds 200 FPS suggests the CPU is not a bottleneck at this resolution; the GPU is doing most of the heavy lifting even at lower presets.

At 2560x1440, the GPU's role becomes more dominant. The drop from Low (146.3 FPS) to Medium (93.7 FPS) is 52.6 FPS, which is a larger absolute reduction than at 1080p. This indicates that the RX 6800 XT is being pushed harder as pixel count rises. The gap between High (82.3 FPS) and Ultra (64.2 FPS) is 18.1 FPS, showing that the Ultra preset at 1440p is particularly demanding on the GPU's shading units and memory bandwidth. The CPU's 6 cores and 12 threads appear sufficient to keep up, as frame rates remain high across all presets.

At 3840x2160, the GPU is unequivocally the limiting factor. The scaling from 1440p to 4K is brutal: Medium drops from 93.7 FPS to 59.6 FPS, and High drops from 82.3 FPS to 47.9 FPS. The RX 6800 XT's 4608 shading units and 128 ROPs are simply overwhelmed at 4K with higher presets. The CPU's role diminishes further, as the frame rates at 4K are far below what the i5-12400F could theoretically support. The data shows that the GPU is the primary bottleneck at 4K, while the CPU and GPU are more evenly matched at 1080p and 1440p.

How This Combo Ranks

In the benchmark database, this specific combination of Intel Core i5-12400F and AMD Radeon RX 6800 XT ranks 1142 out of 3723 tested combos for Rust. That places it in the top 31% of all configurations tested for this game. The rank reflects a strong overall result, driven by the GPU's high performance. The RX 6800 XT sits at the 85th percentile among all GPUs, with an average benchmark score of 48477. Its nearest rivals include the NVIDIA RTX A1000 Mobile (1.5% higher score), the Intel Arc A550M (2.5% lower score), the NVIDIA GeForce RTX 5070 Ti (3% lower score), and the AMD Radeon RX Vega 64 (3% lower score). This indicates the GPU is a high-end part that performs competitively against newer and older alternatives.

The CPU, meanwhile, ranks at the 73rd percentile among all CPUs, with an average benchmark score of 19039. Its nearest rivals include the AMD Ryzen 5 7535HS (0% delta), the Intel Core 3 201E (0.1% lower score), the Intel Core i5-1335U (0.3% higher score), and the AMD EPYC 7773X (0.3% higher score). These near-identical scores show that the i5-12400F is a solid mid-range performer, though not exceptional. The combo rank of 1142 out of 3723 suggests that while the GPU contributes heavily to the overall result, the CPU's mid-pack standing prevents this combo from reaching the top tiers. In practical terms for Rust, the rank confirms that this system is well above average for the game, but there is headroom for improvement — particularly by pairing the RX 6800 XT with a higher-ranked CPU. The measured FPS data supports this interpretation: the combo delivers excellent playability at 1080p and 1440p, but the 4K results are constrained by the GPU, while the CPU never appears to be the limiting factor at any resolution.
