Rust

The combination of an AMD Ryzen 7 3700X and an Intel Arc B390 delivers playable performance only at 1920x1080 with Low settings, where it averages 76 FPS. At 2560x1440 and 3840x2160, no preset reaches the 60 FPS threshold. The GPU, which sits in the 9th percentile of all tested GPUs, is the primary constraint. The CPU, by contrast, is in the 84th percentile, making this a heavily GPU-bound pairing. The game Rust, released on 2018-02-07, demands more from the graphics subsystem than this GPU can provide at higher resolutions.

Best Settings per Resolution

At 1920x1080, the only preset that maintains an average of at least 60 FPS is Low, with an average of 76 FPS. Medium drops to 51 FPS, High to 43 FPS, and Ultra to 33 FPS. Therefore, the most demanding preset that stays at or above 60 FPS is Low. The Medium preset at 1080p has a minimum of 44 FPS and a maximum of 59 FPS, so even its peak never reaches the 60 FPS line.

At 2560x1440, no preset qualifies. The highest average is 53 FPS at Low, followed by Medium at 35 FPS, High at 30 FPS, and Ultra at 23 FPS. The Medium preset at 1440p shows a minimum of 30 FPS and a maximum of 41 FPS, confirming that even the best case is far below the threshold. There is no "best settings" that satisfies the 60 FPS condition at this resolution.

At 3840x2160, the situation is worse. Low averages 31 FPS, Medium 21 FPS, High 18 FPS, and Ultra 13 FPS. The Medium preset at 4K has a minimum of 18 FPS and a maximum of 24 FPS. No preset comes close to 60 FPS, and the highest average, 31 FPS at Low, is less than half the target. For users who prioritize frame rate, the only viable configuration is 1080p with Low settings.

Similar Performance Alternatives

The AMD Ryzen 7 3700X has an average benchmark score of 34260 and ranks in the 84th percentile among all CPUs. Its nearest rivals, based on average score, are the AMD Ryzen AI 7 350 (34222, 0.1% higher), AMD EPYC 4244P (34220, 0.1% higher), Intel Core i5-13450HX (34333, 0.2% lower), and Intel Core Ultra 7 165H (34083, 0.5% higher). These CPUs would deliver very similar computational performance in Rust, though the actual frame rate will still be limited by the GPU. The CPU had a launch MSRP of $329, but its current market position is not the focus here.

The Intel Arc B390, on the other hand, has an average benchmark score of 1482 and sits in the 9th percentile. Its nearest rivals are all older NVIDIA parts: GeForce GT 520MX (1463, 1.3% higher), GeForce 800M (1460, 1.5% higher), GeForce GT 625 OEM (1446, 2.5% higher), and GeForce GT 710 (1443, 2.7% higher). These GPUs are all in the same performance class, meaning the Arc B390 is not meaningfully faster than a decade-old entry-level card. In Rust, which can be demanding on both CPU and GPU, the GPU will be the decisive factor. The recorded data shows that even a strong CPU cannot overcome the GPU's limitations.

Measured FPS Breakdown

The following table lists all recorded average, minimum, and maximum frame rates for each resolution and preset. Minimum and maximum values are only available for the Medium preset at each resolution.

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

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

| 3840x2160 | High | 18 | | |

| 3840x2160 | Low | 31 | | |

| 3840x2160 | Medium | 21 | 18 | 24 |

| 3840x2160 | Ultra | 13 | | |

| 2560x1440 | High | 30 | | |

| 2560x1440 | Low | 53 | | |

| 2560x1440 | Medium | 35 | 30 | 41 |

| 2560x1440 | Ultra | 23 | | |

| 1920x1080 | High | 43 | | |

| 1920x1080 | Low | 76 | | |

| 1920x1080 | Medium | 51 | 44 | 59 |

| 1920x1080 | Ultra | 33 | | |

The data shows a consistent pattern: as resolution increases, frame rates fall sharply. At Low settings, the average drops from 76 FPS at 1080p to 53 FPS at 1440p, and then to 31 FPS at 4K. The Medium preset at 1080p averages 51 FPS, with a minimum of 44 FPS and a maximum of 59 FPS. At 1440p Medium, the average is 35 FPS, with a minimum of 30 FPS and a maximum of 41 FPS. At 4K Medium, the average is 21 FPS, with a minimum of 18 FPS and a maximum of 24 FPS. These numbers illustrate that the GPU cannot handle the workload at higher resolutions, and even at 1080p, only the lowest preset provides a smooth experience.

The Verdict

The verdict is clear: this PC can run Rust, but only at 1920x1080 with Low settings, where it averages 76 FPS. The recorded data shows that no other resolution or preset combination meets the 60 FPS threshold. At 2560x1440, the best average is 53 FPS at Low, which is 7 FPS short of the target. At 3840x2160, the best average is 31 FPS at Low, making the game effectively unplayable at that resolution. The GPU's low percentile (9th) is the primary reason. The CPU, with an 84th percentile, is not the limiting factor in most cases, as evidenced by the fact that even at 1080p Ultra the average is only 33 FPS. This indicates that the GPU is the bottleneck across all tested settings.

For users who insist on higher resolutions or higher quality presets, this combination will not deliver a playable experience. The only way to achieve 60 FPS is to run the game at 1080p with the lowest possible graphics settings. Even then, the margin is modest, and any future game updates or added scene complexity could push the average below 60 FPS.

How This Combo Ranks

The combo ranks 3312 out of 3723 tested combinations, placing it in the lower portion of the database. The CPU is above average, but the GPU is far below it. The GPU's 9th percentile means it outperforms only a small fraction of all GPUs in the database, while the CPU's 84th percentile indicates it is better than most. This mismatch explains why the combo only manages playable frame rates at the lowest settings and resolution. In Rust, which can be demanding on both CPU and GPU, the GPU becomes the limiting factor. The recorded FPS data supports this: even at 1080p Low, the average is 76 FPS, but any increase in quality or resolution quickly drops below the 60 FPS threshold. The high CPU score does not compensate for the GPU's weakness, and the overall rank reflects that imbalance.
