Rust

The Intel Core i5-12400 paired with the AMD Radeon RX 7700 is a desktop combination built around a 6-core, 12-thread Alder Lake processor and a 16 GB RDNA 3 graphics card. The CPU has a launch MSRP of $199. Measured frame rates in Rust show that this system comfortably handles 1080p and 1440p play, while 4K requires the lowest preset to stay above the 60 FPS threshold. The data indicates a well-balanced pairing for mainstream gaming, with clear GPU scaling as resolution climbs.

Best Settings per Resolution

For each resolution, the most demanding preset that maintains at least 60 FPS average is as follows:

• 3840x2160 (4K): Low preset — average 70 FPS. Medium drops to 47 FPS, High to 40 FPS, and Ultra to 30 FPS, all below the playable threshold.
• 2560x1440 (1440p): High preset — average 67 FPS. Medium (80 FPS) and Low (119 FPS) also exceed 60, but Ultra falls to 51 FPS.
• 1920x1080 (1080p): Ultra preset — average 75 FPS. All four presets clear 60 FPS, with High at 98, Medium at 116, and Low at 173.

These results come directly from the measured FPS data and the verdict summary, which lists the best playable setting for each resolution.

CPU and GPU Roles

The scaling between resolutions and presets reveals how the workload shifts between the CPU and GPU. At Low settings, average FPS drops from 173 at 1080p to 119 at 1440p and then to 70 at 4K. This steep decline as pixel count increases is a classic sign of GPU-bound behavior — the Radeon RX 7700 is the limiting factor at higher resolutions. At Ultra settings, the same pattern appears: 75 FPS at 1080p, 51 at 1440p, and 30 at 4K, again indicating that the GPU cannot keep pace with the added pixel workload.

At 1080p, the spread between Low and Ultra is 98 FPS (173 vs. 75), which shows that the CPU is capable of feeding the GPU with high frame rates when the graphics load is light. The fact that Low reaches 173 FPS suggests the i5-12400 has enough single-thread performance to avoid bottlenecking at this resolution. Conversely, at 4K the difference between Low and Ultra is only 40 FPS (70 vs. 30), meaning the GPU is saturated even at the lowest preset. The CPU’s role becomes less significant as resolution increases, and the GPU dominates the performance envelope.

The minimum and maximum frame times for the Medium preset further illustrate this. At 1080p, the range is 99 to 133 FPS; at 1440p, it narrows to 68 to 92; and at 4K, it tightens to 40 to 54. As resolution grows, the frame rate ceiling falls and the variance compresses, reinforcing the GPU-bound nature of the workload at higher resolutions.

Measured FPS Breakdown

The table below lists every measured average FPS value from the FACT PACK. Min and max values are only available for the Medium preset; all other settings report only the average.

| Resolution | Settings | Avg FPS | Min FPS | Max FPS |

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

| 3840x2160 | High | 40 | — | — |

| 3840x2160 | Low | 70 | — | — |

| 3840x2160 | Medium | 47 | 40 | 54 |

| 3840x2160 | Ultra | 30 | — | — |

| 2560x1440 | High | 67 | — | — |

| 2560x1440 | Low | 119 | — | — |

| 2560x1440 | Medium | 80 | 68 | 92 |

| 2560x1440 | Ultra | 51 | — | — |

| 1920x1080 | High | 98 | — | — |

| 1920x1080 | Low | 173 | — | — |

| 1920x1080 | Medium | 116 | 99 | 133 |

| 1920x1080 | Ultra | 75 | — | — |

The data shows a consistent step-down in performance as both resolution and quality increase. At 1080p, every setting exceeds 60 FPS, with Medium providing a comfortable 116 FPS average. At 1440p, only Ultra falls below the threshold. At 4K, only Low remains playable.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-12400, based on average benchmark scores, are all within about one percentage point of the CPU’s score. The AMD EPYC 7643 is 0.1% slower, the Intel Core i7-1355U is 0.3% slower, the AMD Ryzen AI 5 330 is 0.7% slower, and the Intel Core i3-14100F is 0.9% faster. In Rust, any of these CPUs would deliver frame rates nearly identical to the i5-12400, meaning the same resolution and preset recommendations would apply.

For the AMD Radeon RX 7700, the closest GPU alternatives are similarly tight. The AMD Radeon R9 370X is 0.1% slower, the AMD Radeon RX 9060 is 1% slower, the AMD Radeon Pro W5500 is 1.1% faster, and the NVIDIA GeForce RTX 3060 Ti is 1.7% slower. These delta percentages refer to average benchmark scores, not Rust-specific numbers, but they indicate that swapping the GPU for any of these parts would yield comparable frame rates in most scenarios.

A system built with the i5-12400 and any of these rival GPUs would likely produce the same playability verdict: 1080p and 1440p at high settings, 4K only on Low.

How This Combo Ranks

Among all tested CPU-GPU combinations for Rust, this pairing ranks 1728 out of 3723. That places it in the upper half of the field — more than half of the tested combos are slower. The CPU itself sits in the 72nd percentile among all CPUs, while the GPU is in the 58th percentile among all GPUs. These percentile figures reflect synthetic benchmark standings, but the in-game rank confirms that the combination is competitive for Rust without being near the top.

The rank is consistent with the measured FPS: strong at 1080p and 1440p, but limited at 4K. Many higher-ranked combos would likely feature more powerful GPUs, while lower-ranked ones would struggle to hit 60 FPS even at 1080p.

A: The minimum measured FPS on Medium at 1080p is 99, with a maximum of 133 and an average of 116.

Q: How does this combo rank among all tested combinations?

A: It ranks 1728th out of 3723 tested combos, placing it in the upper half of the field.

Q: Is the CPU or GPU the bigger bottleneck at 1080p?

A: The data shows a 98 FPS gap between Low (173) and Ultra (75) at 1080p, indicating the GPU is the primary constraint at higher quality settings. The CPU is capable of delivering very high frame rates when the graphics load is low.

The Verdict

The Intel Core i5-12400 + AMD Radeon RX 7700 can run Rust with the following results:

• 1080p: All presets clear 60 FPS. Ultra averages 75 FPS, High 98, Medium 116, and Low 173.
• 1440p: High, Medium, and Low are playable, with High at 67 FPS. Ultra falls to 51 FPS and is not recommended.
• 4K: Only Low achieves 60 FPS (70 average). Medium (47), High (40), and Ultra (30) are below the playable threshold.

This system is well-suited for 1080p and 1440p gaming, where it can handle high or ultra settings smoothly. At 4K, it requires the lowest preset to maintain playable frame rates. For players targeting 1080p or 1440p, this combination delivers a solid experience in Rust; for 4K, it is a viable option only with reduced visual fidelity.
