Rust

The Intel Core i5-12400F paired with the AMD Radeon RX 5700 XT delivers a solid 1080p and 1440p experience in Rust, but it cannot maintain playable frame rates at 4K. At 1920x1080, the combo is clearly capable, with multiple settings presets clearing the 60 FPS threshold comfortably. At 2560x1440, the system remains playable but requires a reduction in visual quality. The data indicates that 4K resolution is out of reach for this hardware, as even the lowest settings preset falls just short of the 60 FPS target.

Best Settings per Resolution

1920x1080: The most demanding preset that stays at or above 60 FPS is High, which achieves an average of 79.8 FPS. This is the optimal balance, as the Ultra preset drops to 58.1 FPS average, which is below the 60 FPS playable threshold.

2560x1440: The best playable setting is Medium, delivering an average of 65.6 FPS. While the Low preset runs faster at 94.9 FPS, Medium offers a better visual experience while still maintaining a comfortable margin above the 60 FPS target. The High preset at this resolution falls short at 54.7 FPS.

3840x2160: No settings preset is playable at this resolution. The closest option is Low, which averages 58 FPS, just under the 60 FPS requirement. Medium and High are significantly lower at 37.4 and 31.9 FPS respectively, while Ultra drops to 21.5 FPS.

CPU and GPU Roles

The benchmark data reveals a clear pattern of GPU limitation as resolution increases. At 1920x1080, the CPU has more headroom, allowing the GPU to push higher frame rates. The scaling from Low to Ultra at 1080p shows a drop from 133.4 to 58.1 FPS, a reduction of 75.3 FPS. This wide spread indicates that the GPU is the primary bottleneck at this resolution, as the CPU can feed frames quickly enough to let the GPU work harder at lower settings.

Moving to 2560x1440, the frame rates compress downward. The Low preset drops from 133.4 at 1080p to 94.9 at 1440p, a decrease of 38.5 FPS. The Medium preset falls from 89.3 to 65.6, and High from 79.8 to 54.7. This consistent reduction across all settings shows that the GPU is increasingly strained by the higher pixel count, while the CPU has less impact on the overall result.

At 3840x2160, the GPU is severely overloaded. The Low preset yields only 58 FPS, and Ultra falls to 21.5 FPS. The gap between Low and Ultra at 4K is 36.5 FPS, much smaller than the 75.3 FPS gap at 1080p. This compression indicates that the GPU is saturated even at the lowest settings, and the CPU's role is minimized. The CPU, with its 6 cores and 12 threads, is sufficient to feed the GPU at 1080p and 1440p, but at 4K the GPU becomes the sole limiting factor.

The data also shows that the CPU's performance is adequate for this game across all tested resolutions. The i5-12400F has a strong single-thread score of 1680 in Cinebench R23, which is relevant for Rust's gameplay. The GPU's 8 GB of GDDR6 memory and 448.0 GB/s bandwidth are sufficient for 1080p and 1440p, but the 4K results suggest that the memory capacity and bandwidth are not enough to maintain playable frame rates at that resolution.

Measured FPS Breakdown

1920x1080:

• Low: Average 133.4 FPS
• Medium: Average 89.3 FPS
• High: Average 79.8 FPS
• Ultra: Average 58.1 FPS

The 1080p results show a clear tiering. Low settings deliver the highest frame rate by a wide margin, with 133.4 FPS. Medium and High are closer together, with a gap of 9.5 FPS between them. The Ultra preset is the only option that falls below the 60 FPS threshold, making it unsuitable for smooth gameplay.

2560x1440:

• Low: Average 94.9 FPS
• Medium: Average 65.6 FPS
• High: Average 54.7 FPS
• Ultra: Average 37.7 FPS

At 1440p, the Low preset still provides a very smooth experience at 94.9 FPS. Medium is just above the playable threshold at 65.6 FPS. The High preset drops below 60 FPS, and Ultra is significantly lower at 37.7 FPS. The performance gap between Low and Ultra is 57.2 FPS, showing the GPU's sensitivity to settings at this resolution.

3840x2160:

• Low: Average 58 FPS
• Medium: Average 37.4 FPS
• High: Average 31.9 FPS
• Ultra: Average 21.5 FPS

At 4K, even the Low preset fails to reach 60 FPS, with 58 FPS being the best result. The drop from Low to Medium is 20.6 FPS, which is substantial. High and Ultra are both far below playable levels. The data shows that this resolution is not viable for this hardware combination.

FAQ

Q: Can this system run Rust at 1080p with the highest possible settings?

A: No. The Ultra preset at 1920x1080 averages 58.1 FPS, which is below the 60 FPS playable threshold. The High preset is the best option, averaging 79.8 FPS.

Q: What is the best resolution for this CPU and GPU combo?

A: The best experience is at 1920x1080 on High settings, which delivers 79.8 FPS. This provides a high frame rate with good visual quality. At 2560x1440, the Medium preset is the best playable option at 65.6 FPS.

Q: Is 1440p gaming viable with this hardware?

A: Yes, but only with reduced settings. The Medium preset at 2560x1440 averages 65.6 FPS, clearing the 60 FPS requirement. The High preset at 54.7 FPS is not playable.

Q: Why is 4K not recommended for this system?

A: At 3840x2160, the best result is 58 FPS on the Low preset, which is just below the 60 FPS target. All other presets are significantly lower, with Ultra at 21.5 FPS. The GPU is the limiting factor at this resolution.

Q: How much performance is lost when moving from 1080p to 1440p?

A: On the Low preset, the frame rate drops from 133.4 FPS at 1080p to 94.9 FPS at 1440p, a decrease of 38.5 FPS. On the High preset, the drop is from 79.8 to 54.7 FPS, a decrease of 25.1 FPS.

Q: Does the CPU or GPU limit performance in Rust?

A: The GPU is the primary bottleneck. The CPU has sufficient performance to feed frames at 1080p and 1440p, but the GPU cannot maintain 60 FPS at 4K even on Low settings. The scaling between resolutions confirms that the GPU is the main constraint.

The Verdict

This combination can run Rust, but the experience depends heavily on the target resolution. At 1920x1080, the system is fully capable, with the High preset delivering 79.8 FPS and the Low preset reaching 133.4 FPS. The Ultra preset is the only option that fails to clear the 60 FPS threshold, averaging 58.1 FPS.

At 2560x1440, the system remains playable but requires compromise. The Medium preset averages 65.6 FPS, which is above the threshold. The Low preset is much faster at 94.9 FPS, but the High preset drops to 54.7 FPS, which is not playable. Users who prefer higher visual fidelity should stick to 1080p.

At 3840x2160, the system cannot achieve 60 FPS at any settings preset. The Low preset is closest at 58 FPS, but it still falls short. The recorded data shows that 4K is not a viable option for this hardware in Rust.

Overall, the verdict is positive for 1080p and 1440p users. The best experience is at 1080p on High settings, which offers a strong balance of performance and visual quality. For 1440p, Medium settings provide a playable experience, though users should expect lower frame rates than at 1080p.

How This Combo Ranks

The Intel Core i5-12400F and AMD Radeon RX 5700 XT combination ranks 2738 out of 3723 tested combos in Rust. This places the system in the lower portion of the database, which is consistent with the 4K performance results. The GPU sits at the 59th percentile among all GPUs, and the CPU at the 73rd percentile among all CPUs, but the game's demanding nature at higher resolutions brings the overall combo ranking down.

The CPU's nearest rivals include the AMD Ryzen 5 7535HS, which scores nearly identically with a 0% delta, and the Intel Core 3 201E, which is 0.1% behind. The GPU's nearest rival is the AMD Radeon Pro 5600M, which is only 0.1% ahead in average score. These close margins indicate that the individual components are mid-pack performers.

The ranking of 2738 out of 3723 shows that this combination is better suited for 1080p gaming than for higher resolutions. The data indicates that the system is capable of delivering a smooth experience at 1080p and a playable one at 1440p, but it does not have the headroom for 4K. For users targeting 1080p, this combo is a solid choice, but those aiming for 1440p or 4K would need to consider more powerful hardware.
