Similar Performance Alternatives

The CPU in this pairing, the AMD Ryzen 5 8400F, sits very close to several other processors in the database's aggregate benchmark scores. Its nearest rival is the AMD Ryzen 5 7500F, which scores 24,964 against the 8400F's 25,005, a delta of just 0.2%. The Intel Core i7-11850H is 0.3% behind, and the Intel Core i7-13620H trails by 0.4%. On the other side, the AMD EPYC 9474F leads by 0.4%. What this means in practice is that swapping the 8400F for any of these chips would produce nearly identical CPU-bound behavior in Rust at the tested resolutions; the differences are well within run-to-run variance.

The GPU side is a very different story. The Intel Arc B370 scores just 1,184 in the 3DMark Steel Nomad DX12 test, placing it in the 5th percentile of all GPUs. Its nearest rivals are all legacy parts: the ATI Mobility Radeon HD 5570 is 0.2% faster, the ATI Radeon HD 5770 is 0.5% faster, and the AMD Radeon HD 7650M is 0.7% faster. The AMD FirePro M2000 trails by 1.4%. The data shows that this GPU is operating in a performance tier populated by integrated and very old discrete graphics solutions. If a user were to swap the Arc B370 for any of these rivals, the frame rate impact would be minimal, meaning the GPU is the clear bottleneck in this system.

CPU and GPU Roles

For this pairing, the GPU dictates playability at every resolution. The CPU has ample headroom, as evidenced by its 77th percentile ranking among all CPUs, but the Arc B370's 5th percentile GPU score means it cannot feed frames fast enough to stress the processor. Benchmark results confirm this pattern: at 1920x1080, the average frame rate climbs from 39 FPS on High to 69 FPS on Low, a 77% increase purely from lowering graphics load. At 2560x1440, the same settings change yields 27 FPS to 48 FPS, an improvement of 78%. At 3840x2160, Low produces 28 FPS versus 16 FPS on High, a 75% jump. The consistency of these scaling ratios across resolutions indicates the GPU is the limiting factor; if the CPU were the constraint, lowering resolution would not produce such proportional gains.

The resolution scaling itself reinforces this conclusion. Dropping from 3840x2160 to 1920x1080 at Low settings raises the average from 28 FPS to 69 FPS, a 146% improvement. At High settings, the same resolution drop moves from 16 FPS to 39 FPS, a 144% gain. These are GPU-bound scaling characteristics. The CPU's role is essentially static: it maintains the game's logic, physics, and entity updates without becoming the constraint. The recorded data shows no scenario where the CPU prevents the GPU from reaching its maximum output, which is why the verdict at 1440p and 4K is unplayable regardless of preset.

Best Settings per Resolution

At 3840x2160, no preset achieves 60 FPS. The best recorded result is 28 FPS at Low settings. Medium produces 19 FPS, High drops to 16 FPS, and Ultra falls to 12 FPS. The database lists no playable settings for this resolution, meaning the most demanding preset that stays at or above 60 FPS does not exist here.

At 2560x1440, the situation is similar. Low settings yield 48 FPS, which is the highest average across all presets at this resolution, but it still falls short of the 60 FPS threshold. Medium averages 32 FPS, High averages 27 FPS, and Ultra averages 20 FPS. Again, no preset meets the playability bar.

At 1920x1080, Low settings deliver 69 FPS average, clearing the 60 FPS threshold. This is the only playable preset at this resolution. Medium drops to 46 FPS, High to 39 FPS, and Ultra to 30 FPS. The data indicates that a user must accept Low settings at 1080p to maintain fluid gameplay. The minimum frame rates recorded for Medium at 1080p are 39 FPS, which further confirms that even the next step up from Low introduces noticeable stutter potential.

The Verdict

This PC cannot run Rust at 60 FPS in most configurations. The verdict by resolution is unambiguous: at 3840x2160, there are no playable settings, meaning no preset reaches 60 FPS. The best average is 28 FPS at Low, which is less than half the playable threshold. At 2560x1440, the same verdict applies: no playable settings. Low averages 48 FPS, which is 80% of the threshold but still below it. Only at 1920x1080 does the system find a playable configuration: Low settings at 69 FPS average. That is the sole combination of resolution and preset that clears the 60 FPS bar.

The practical takeaway is that this hardware is suited for 1080p gaming with reduced graphical fidelity. Users who prioritize visual quality will have to sacrifice it entirely to reach playable frame rates. The GPU's 5th percentile ranking among all GPUs is the root cause; the CPU's 77th percentile ranking cannot compensate. The measured frame rates show a consistent pattern: even at the lowest settings, 1440p and 4K are out of reach, and 1080p only barely crosses the threshold.

FAQ

Q: What is the highest average frame rate this system achieves in Rust?

A: The highest recorded average is 69 FPS at 1920x1080 with Low settings. No other resolution or preset combination exceeds this value.

Q: Can this system run Rust at 2560x1440?

A: No. The best result at 1440p is 48 FPS at Low settings, which is below the 60 FPS playable threshold. The verdict lists no playable settings for 2560x1440.

Q: How does the CPU compare to its nearest rivals?

A: The AMD Ryzen 5 8400F scores 25,005 on average, within 0.4% of the AMD Ryzen 5 7500F, Intel Core i7-11850H, and Intel Core i7-13620H. The AMD EPYC 9474F is 0.4% faster.

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

A: The Intel Arc B370 scores 1,184 in 3DMark Steel Nomad DX12. The closest rival, the ATI Mobility Radeon HD 5570, is 0.2% faster, while the AMD FirePro M2000 is 1.4% slower.

Q: What is the frame rate difference between Low and Ultra at 1080p?

A: At 1920x1080, Low averages 69 FPS while Ultra averages 30 FPS. That is a 39 FPS drop, or a 57% reduction in average frame rate.

Q: Does lowering resolution help this system reach 60 FPS?

A: Only at 1080p with Low settings. At 1440p, the best average is 48 FPS, and at 4K, the best average is 28 FPS. Neither reaches the 60 FPS threshold.

How This Combo Ranks

The AMD Ryzen 5 8400F and Intel Arc B370 combination ranks 3,437 out of 3,723 tested combos in Rust. This places the system in the bottom 8% of all configurations in the database. The ranking reflects the GPU's severe limitation: the Arc B370's 5th percentile standing among GPUs drags the entire system down, despite the CPU's respectable 77th percentile position. The data shows that this combo outperforms only 286 other tested configurations, which are likely older or more imbalanced pairings. For context, the combo sits far below the median tested configuration, and the measured frame rates confirm this ranking is not an artifact of the ranking methodology. The system's only playable scenario, 1080p Low at 69 FPS, is a marginal pass that leaves no headroom for demanding scenes or multiplayer population spikes common in Rust. Users seeking a smoother experience would need to consider a different GPU, as the CPU is not the limiting factor in this pairing.
