Rust

The AMD Ryzen 7 7700 and Intel Arc B390 combination delivers a narrow band of playability in Rust, a survival title that leans heavily on both CPU and GPU resources. The recorded data shows that this pairing can handle the game, but only at the lowest settings at 1080p. At higher resolutions, the frame rates fall well below the 60 FPS threshold that the database uses to define playable performance. The measurements paint a clear picture: this is a system for playing Rust at entry-level graphical quality, not for pushing high refresh rates or high fidelity.

Measured FPS Breakdown

The benchmark results for this CPU and GPU pairing show a significant performance drop as resolution increases. At 1920x1080, the system produces its most usable frame rates. The Low preset averages 76 FPS, which is the only measured setting to clear the playable threshold. The Medium preset averages 51 FPS, with a recorded range between 44 and 59 FPS. High settings drop the average to 43 FPS, while the Ultra preset falls to an average of 33 FPS.

Moving to 2560x1440, the performance declines substantially. The Low preset averages 53 FPS, which is below the 60 FPS target but not by a large margin. Medium settings at this resolution average 35 FPS, with a range of 30 to 41 FPS. High settings produce an average of 30 FPS, and Ultra falls to 23 FPS. None of these results reach the playable threshold.

At 3840x2160, the frame rates become marginal for any kind of responsive play. Low settings average 31 FPS. Medium averages 21 FPS, with a recorded range of 18 to 24 FPS. High drops to 18 FPS, and Ultra falls to 13 FPS. These numbers indicate that 4K gaming is not viable with this hardware combination in Rust, regardless of the quality preset selected.

The data shows a consistent pattern: each step down in resolution or settings yields a proportional increase in frame rate. The gap between Low and Ultra is substantial at every resolution, highlighting the GPU workload scaling. The min and max FPS values are only recorded for the Medium preset at each resolution, showing a narrow band of variance at 1440p and 4K, while the 1080p Medium range is wider.

Best Settings per Resolution

The database identifies the most demanding preset that remains at or above 60 FPS for each resolution. For this CPU and GPU combination, the results are straightforward.

At 1920x1080, the only playable setting is Low. The Low preset delivers an average of 76 FPS, which comfortably exceeds the 60 FPS threshold. The Medium preset falls short with an average of 51 FPS, so it cannot be considered playable by this metric. The best playable setting at this resolution is Low, with 76 FPS.

At 2560x1440, there are no playable settings recorded. The Low preset averages 53 FPS, which is below the 60 FPS threshold. Medium averages 35 FPS, High averages 30 FPS, and Ultra averages 23 FPS. The database lists no best settings for this resolution because none clear the playable bar.

At 3840x2160, the situation is similar. The Low preset averages 31 FPS, Medium averages 21 FPS, High averages 18 FPS, and Ultra averages 13 FPS. No settings achieve the required 60 FPS, so no best settings are assigned.

The verdict data confirms this: the 1080p Low preset is the only playable configuration across all tested resolutions and quality levels.

CPU and GPU Roles

The scaling between resolutions and presets reveals which component is the limiting factor in Rust for this combination. The CPU, an AMD Ryzen 7 7700 with 8 cores and 16 threads, has a strong benchmark profile. Its multi-threaded scores are solid, with a Cinebench R23 multi-core score of 18760 and a Geekbench multi-core score of 15371. The single-thread performance is also respectable, with a Geekbench single-core score of 2525 and a Cinebench R23 single-core score of 1930.

The GPU, an Intel Arc B390, is the clear bottleneck in this pairing. Its average benchmark score is 1482, and its percentile ranking against all GPUs is only 9%. The nearest rivals are low-end mobile or OEM parts, such as the GT 520MX and GT 710. The GPU also has a low pixel rate of 60.00 GPixel/s and a texture rate of 120.0 GTexel/s, which are not competitive for modern titles.

The frame rate data shows that reducing resolution from 1080p to 1440p has a severe impact on performance. At Low settings, the average FPS drops from 76 at 1080p to 53 at 1440p, a reduction of about 30%. At 4K Low, the average falls to 31 FPS, which is less than half of the 1080p result. This scaling indicates that the GPU is the primary bottleneck, as a stronger GPU would be able to maintain higher frame rates at higher resolutions.

The CPU does show its influence in the 1080p results. At 1080p Low, the average of 76 FPS is well above the GPU's typical output for more demanding settings, suggesting that the CPU can feed the GPU with enough data to keep it busy. However, the GPU's limited shader processing power becomes clear once the resolution increases, and the frame rates collapse. The data suggests that the CPU is not the limiting factor at any resolution, but the GPU is unable to keep up beyond the 1080p Low preset.

FAQ

Q: What is the highest average FPS this combo achieves in Rust?

A: The highest recorded average FPS is 76, achieved at 1920x1080 with the Low preset.

Q: Can this system run Rust at 2560x1440?

A: No, the database does not record any playable settings at 2560x1440. The Low preset averages 53 FPS, which is below the 60 FPS threshold.

Q: What is the performance difference between the Low and Ultra presets at 1080p?

A: At 1920x1080, the Low preset averages 76 FPS, while the Ultra preset averages 33 FPS. That creates a 43 FPS gap between the lowest and highest quality settings.

Q: How does the Intel Arc B390 GPU compare to its nearest rivals?

A: The GPU's average benchmark score of 1482 is 1.3% ahead of the GT 520MX, 1.5% ahead of the GeForce 800M, 2.5% ahead of the GT 625 OEM, and 2.7% ahead of the GT 710.

How This Combo Ranks

In the database's rankings for Rust, this specific CPU and GPU combination is placed at rank 3312 out of 3723 tested combinations. That places it in the lower 10% of all tested systems. The rank reflects the GPU's low performance percentile relative to other parts. The GPU's 9th percentile ranking drags the overall system, despite the CPU's solid 87th percentile standing.

The gap between the CPU and GPU performance is stark. The CPU is in the 87th percentile, while the GPU is in the 9th percentile. This indicates that the system is heavily unbalanced for gaming, with a very strong processor paired with a very weak graphics card. In a game like Rust, which relies on both CPU and GPU for rendering, the GPU's limitations dominate the final frame rates.

The measured FPS data aligns with this ranking. The 1080p Low result of 76 FPS is the only positive point, while the other settings and resolutions fall well below the playable threshold. The system is not a good fit for modern gaming beyond the most basic settings.

The Verdict

Can this PC run Rust? Yes, but only in a limited capacity. The data shows that the AMD Ryzen 7 7700 and Intel Arc B390 combination can play Rust at 1920x1080 with the Low preset, where it averages 76 FPS. This is the only configuration that clears the 60 FPS playable threshold.

At 2560x1440 and 3840x2160, the system is not playable by the database's standard. The best results at these resolutions are 53 FPS and 31 FPS, respectively, both at the Low preset, and both below the 60 FPS mark. The CPU and GPU roles are clear: the CPU is strong, but the GPU is the limiting factor. For a stable 60 FPS experience, the system must be kept at 1080p Low, which is the best settings per resolution for this hardware. Any increase in resolution or quality settings will result in frame drops below the playable threshold.
