Rust

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 5070 delivers a strong 1080p and 1440p experience in Rust, but the data reveals a clear ceiling at 4K. The measured frame rates show that the RTX 5070 is the dominant component at higher resolutions, while the i5-12400F’s six performance cores provide enough headroom to keep frame rates high at lower settings. This combination ranks in the top 20% of tested combos for Rust, making it a viable option for high-refresh-rate gaming without requiring a flagship CPU.

Settings Recommendations

The measured data indicates that the Medium preset at 1080p offers the best balance of visual quality and performance for most users. At 1920x1080, Medium produces an average of 161 FPS, with a minimum of 137 FPS and a maximum of 186 FPS. This is a significant jump from the High preset’s 136 FPS average, and it keeps frame rates well above the 144Hz refresh rate common on modern monitors. The Low preset at 1080p reaches 205 FPS, which is excellent for competitive play, but the visual compromise is substantial for a survival game where environmental readability matters.

At 2560x1440, the Medium preset again emerges as the sweet spot. It delivers an average of 111 FPS, with a minimum of 94 FPS and a maximum of 128 FPS. This is more than enough for a smooth experience on a 1440p 120Hz or 144Hz display. The High preset at 1440p drops to 94 FPS, which is still playable but leaves less headroom for demanding scenes with multiple players or large bases. The Ultra preset at 1440p falls to 71 FPS, which is borderline for fast-paced combat, so Medium is the recommended choice for this resolution.

For 3840x2160, the situation changes dramatically. The Medium preset yields only 66 FPS, with a minimum of 56 FPS, which is below the 60 FPS target for many players. The High preset drops further to 55 FPS, and Ultra falls to 42 FPS. The Low preset at 4K reaches 98 FPS, but the visual quality at Low is poor enough that it defeats the purpose of playing at 4K. Therefore, the data suggests that 4K gaming with this combo is only viable at Medium settings if you can tolerate occasional dips below 60 FPS, or at Low if you prioritize frame rate over visuals. For most users, 1440p Medium provides the best overall experience.

The rank also indicates that the combo is not overkill for 1080p gaming, as the CPU can still push frame rates above 200 FPS at Low settings, but it excels at 1440p where the GPU takes over.

Measured FPS Breakdown

At 1920x1080, the combo delivers its highest frame rates across all settings. The Low preset averages 205 FPS, which is ideal for competitive play or high-refresh-rate monitors. The Medium preset averages 161 FPS, with a minimum of 137 FPS and a maximum of 186 FPS, making it the most consistent option for smooth gameplay. The High preset drops to 136 FPS, still well above 100 FPS, while the Ultra preset averages 104 FPS, which is the first setting to fall below the 144 FPS mark. The data shows that the RTX 5070 has headroom at 1080p, and the i5-12400F is not limiting performance even at the highest settings.

At 2560x1440, the frame rates scale down as expected. The Low preset averages 165 FPS, which is a 19.5% drop from 1080p Low, indicating the GPU is becoming more involved. The Medium preset averages 111 FPS, with a minimum of 94 FPS and a maximum of 128 FPS, which is a 31% drop from 1080p Medium. The High preset averages 94 FPS, a 30.9% drop from 1080p High, while the Ultra preset averages 71 FPS, a 31.7% drop from 1080p Ultra. The consistency of these percentage drops suggests that the GPU is the primary bottleneck at this resolution, with the CPU providing stable frame delivery.

At 3840x2160, the performance drops become more pronounced. The Low preset averages 98 FPS, which is a 52.2% drop from 1080p Low, showing the GPU is heavily loaded. The Medium preset averages 66 FPS, with a minimum of 56 FPS, a 59% drop from 1080p Medium, indicating that 4K pushes the RTX 5070 to its limits. The High preset averages 55 FPS, a 59.6% drop from 1080p High, while the Ultra preset averages 42 FPS, a 59.6% drop from 1080p Ultra. The data clearly shows that 4K is not viable for smooth gameplay at High or Ultra settings, and even Medium dips below 60 FPS.

Resolution Scaling

The FPS drops from 1080p to 4K reveal the limiting component in this combo. From 1080p to 1440p, the average FPS drops by approximately 30% across all settings, which is consistent with the pixel count increase of 78% (from 2.07 million pixels to 3.69 million pixels). This suggests that the GPU is the primary limiter at these resolutions, as the CPU has enough headroom to maintain frame rates.

From 1440p to 4K, the drops become more severe. At Low settings, the FPS drops from 165 to 98, a 40.6% decrease. At Medium, it drops from 111 to 66, a 40.5% decrease. At High, it drops from 94 to 55, a 41.5% decrease, and at Ultra, it drops from 71 to 42, a 40.8% decrease. These larger percentage drops indicate that the RTX 5070’s 12 GB of GDDR7 memory and 192-bit memory bus are reaching their limits, as the 4K resolution demands significantly more memory bandwidth.

The data shows that the RTX 5070 is the clear bottleneck at 4K, as the CPU’s performance is unlikely to change with resolution. The i5-12400F’s 6 cores and 12 threads provide consistent performance across all resolutions, as evidenced by the similar FPS scaling patterns. At 1080p, the combo is CPU-bound at Low settings (205 FPS), but as resolution increases, the GPU becomes the limiting factor. This means that for 4K gaming, a stronger GPU would be required to maintain 60+ FPS at Medium or higher settings.
