Rust

The Intel Core i5-13400F and AMD Radeon RX 6800 XT form a desktop combination that has been measured in Rust, with frame rates recorded across three resolutions and four quality presets. The data shows that this system clears the 60 FPS playable threshold at 1080p and 1440p on every preset, while 4K requires dropping to Low settings. The combo ranks 1146th out of 3723 tested configurations, placing it in the upper third of all tested systems. The CPU sits in the 77th percentile of all CPUs, and the GPU in the 85th percentile, indicating a well-balanced pairing with the GPU slightly stronger relative to its peers.

Best Settings per Resolution

The most demanding preset that stays at or above 60 FPS at each resolution is as follows:

• 3840x2160 (4K): Low settings, averaging 83 FPS. Medium drops to 55.6, High to 48.1, and Ultra to 35.7, so only Low is playable.
• 2560x1440 (1440p): Ultra settings, averaging 65.1 FPS. All presets exceed 60 FPS here: Low at 146.7, Medium at 95.8, High at 83.4, and Ultra at 65.1.
• 1920x1080 (1080p): Ultra settings, averaging 88.1 FPS. Low reaches 206.8, Medium 142, and High 117.6, all well above the threshold.

These results indicate that the system is fully capable of high-refresh-rate play at 1080p and 1440p, but 4K is limited to the lowest preset for a smooth experience.

FAQ

Q: Can this combo run Rust at 4K with High settings?

A: No. At 3840x2160 with High settings, the average FPS is 48.1, which is below the 60 FPS playable threshold. Only Low settings at 4K achieve 60+ FPS, with an average of 83 FPS.

Q: What is the best preset for 1440p?

A: Ultra, which averages 65.1 FPS. All presets at 1440p exceed 60 FPS, so players can choose the highest quality without sacrificing smoothness.

Q: How does the i5-13400F compare to its nearest CPU rivals?

A: The i5-13400F has an average benchmark score of 25292. It is 0.4% higher than the AMD Ryzen 7 6800H (25201) and 0.3% lower than the Intel Core 5 120 (25362) and AMD Ryzen 5 5600X3D (25365). It is essentially tied with the AMD Ryzen 9 6900HS (25284, 0% delta).

Q: What is the combo's rank among all tested systems?

A: The combo ranks 1146th out of 3723 tested configurations. This places it in the upper third of the field, meaning it outperforms the majority of tested systems.

Q: How does the RX 6800 XT compare to its nearest GPU rivals?

A: The RX 6800 XT has an average benchmark score of 48477. It is 1.5% higher than the NVIDIA RTX A1000 Mobile (47743) and 2.5% lower than the Intel Arc A550M (49737), 3% lower than the NVIDIA GeForce RTX 5070 Ti (49957), and 3% lower than the AMD Radeon RX Vega 64 (50001).

Q: Is the game more CPU or GPU bound at 1080p?

A: At 1080p, the FPS ranges from 206.8 on Low to 88.1 on Ultra, showing that the GPU still has a significant impact on performance. However, the very high frame rates on Low suggest the CPU is not the limiting factor at this resolution. At 4K, the FPS drops dramatically, indicating a GPU bottleneck.

How This Combo Ranks

The combo's rank of 1146 out of 3723 tested configurations places it in the upper third of all systems tested for Rust. This is a strong showing, especially considering the CPU's 77th percentile and GPU's 85th percentile among their respective component pools. The rank reflects the measured frame rates, not just synthetic scores, and the data shows that the system can handle the game at high settings on mainstream resolutions. The gap between the CPU and GPU percentiles suggests that the GPU is the more dominant component in this pairing, which aligns with the observed scaling: at higher resolutions, the GPU becomes the primary bottleneck. The rank also indicates that while many combos outperform this one, a significant majority of tested systems fall below it, making this a capable setup for Rust.

Similar Performance Alternatives

Based on average benchmark scores, the i5-13400F is closely matched by several CPUs. The AMD Ryzen 9 6900HS has a score of 25284 (0% delta), the Intel Core 5 120 scores 25362 (-0.3%), the AMD Ryzen 5 5600X3D scores 25365 (-0.3%), and the AMD Ryzen 7 6800H scores 25201 (+0.4%). Swapping the CPU to any of these would yield nearly identical CPU-bound performance in Rust, as the differences are within a fraction of a percent.

For the GPU, the RX 6800 XT is within 3% of several alternatives. The Intel Arc A550M (49737, -2.5%), NVIDIA GeForce RTX 5070 Ti (49957, -3%), and AMD Radeon RX Vega 64 (50001, -3%) are all slightly ahead, while the NVIDIA RTX A1000 Mobile (47743, +1.5%) is slightly behind. A system with any of these GPUs would produce similar frame rates in Rust, assuming the CPU remains the same. These alternatives are based on synthetic benchmark averages, but the measured FPS for this combo provides a concrete reference point.

Measured FPS Breakdown

The following table lists the average FPS for each resolution and preset combination. No minimum or maximum frame rates were recorded in the data.

| Resolution | Settings | Avg FPS |

|------------|----------|---------|

| 3840x2160 | High | 48.1 |

| 3840x2160 | Low | 83 |

| 3840x2160 | Medium | 55.6 |

| 3840x2160 | Ultra | 35.7 |

| 2560x1440 | High | 83.4 |

| 2560x1440 | Low | 146.7 |

| 2560x1440 | Medium | 95.8 |

| 2560x1440 | Ultra | 65.1 |

| 1920x1080 | High | 117.6 |

| 1920x1080 | Low | 206.8 |

| 1920x1080 | Medium | 142 |

| 1920x1080 | Ultra | 88.1 |

The data shows a clear progression: at each resolution, lowering the preset increases FPS, and at each preset, lowering the resolution increases FPS. The largest absolute jump occurs from 4K to 1440p at Low settings (83 to 146.7), while the smallest is from 1440p to 1080p at Ultra (65.1 to 88.1). This pattern is consistent with a GPU-bound scenario at higher resolutions.

The Verdict

This PC can run Rust at 60+ FPS on all presets at 1080p and 1440p. At 1080p, the Ultra preset averages 88.1 FPS, and at 1440p, Ultra averages 65.1 FPS. At 4K, only Low settings achieve the 60 FPS threshold, with an average of 83 FPS; Medium (55.6), High (48.1), and Ultra (35.7) all fall short. Therefore, for a 60 FPS target, the system is fully capable at 1080p and 1440p with maximum quality, and at 4K only with the lowest preset. The best settings per resolution are: 1080p Ultra (88.1 FPS), 1440p Ultra (65.1 FPS), and 4K Low (83 FPS). The playable threshold is 60 FPS, and the data confirms that this combo meets or exceeds it in all but the most demanding 4K presets.

CPU and GPU Roles

The scaling between resolutions and presets reveals which component dominates performance. At 1080p, the FPS ranges from 206.8 on Low to 88.1 on Ultra, a 57% reduction. At 1440p, the range is 146.7 to 65.1, a 56% reduction. At 4K, the range is 83 to 35.7, a 57% reduction. The relative drop is similar across resolutions, but the absolute values are much lower at 4K, indicating that the GPU is the primary constraint at higher resolutions. The CPU's high single-thread performance (Geekbench single 1996, Cinebench R23 single 3191) and multi-thread capability (Cinebench R23 multi 22604) allow it to feed the GPU effectively at lower resolutions, where frame rates are high. The GPU's 16 GB of VRAM and 512.0 GB/s bandwidth are sufficient for Rust's demands, but the raw compute power (20.74 TFLOPS FP32) becomes the limiting factor as resolution increases.

The data shows that at 1080p, the CPU is not the bottleneck, as even the most demanding preset yields 88.1 FPS. At 4K, the GPU is clearly the limiting factor, since even Low settings only reach 83 FPS, while Medium drops to 55.6. The CPU's percentile (77) is lower than the GPU's (85), reinforcing that the GPU is the stronger component relative to its peers. This asymmetry explains why the system performs well at 1080p and 1440p but struggles at 4K: the GPU cannot maintain high frame rates at that resolution, regardless of the CPU's capability. For players targeting 4K, a more powerful GPU would be necessary, while the CPU would remain sufficient. At 1080p and 1440p, the balance is excellent, with both components contributing to a smooth experience.
