Rust

Best Settings per Resolution

The recorded data for this combination shows a clear pattern: 60 FPS is only achievable at the lowest settings and only at 1080p. At 3840x2160, no preset reaches the playable threshold. The High preset averages 16 FPS, Medium averages 19 FPS, Low averages 28 FPS, and Ultra averages 12 FPS. None of these approach 60 FPS, and the best available option is Low at 28 FPS, though it remains far below playable.

At 2560x1440, the situation improves slightly but still falls short. High averages 27 FPS, Medium averages 32 FPS, Low averages 48 FPS, and Ultra averages 20 FPS. The closest to the 60 FPS target is Low at 48 FPS, but it still misses the threshold by a significant margin. No settings preset at this resolution can be recommended for smooth gameplay.

At 1920x1080, the Low preset is the only one that clears 60 FPS, averaging 69 FPS. This is the single playable configuration in the entire dataset. The next best option is Medium at 46 FPS, which falls below the threshold. High averages 39 FPS, and Ultra averages 30 FPS. For users who insist on 1080p, Low is the only viable choice, and it delivers a comfortable margin above the 60 FPS line.

CPU and GPU Roles

The benchmark results indicate a heavy GPU bottleneck across all resolutions. The Intel Arc B370, with its 1280 shading units and 6.144 TFLOPS FP32 throughput, is clearly the limiting factor. The Intel Core i7-12700K, a 12-core, 20-thread Alder Lake processor with a 5.00 GHz boost clock, has ample compute headroom for this title. Its Cinebench R23 multi-core score of 19784 and single-core score of 1850.5 place it in the 84th percentile among all CPUs, suggesting it is not struggling to feed the GPU.

The scaling between resolutions confirms this. Moving from 1920x1080 to 2560x1440 at Low settings drops the average FPS from 69 to 48, a 30% reduction. Moving further to 3840x2160 at Low settings drops it to 28 FPS, another 42% reduction. This steep decline with increasing pixel count is characteristic of a GPU-bound scenario. If the CPU were the constraint, resolution changes would have a much smaller impact on frame rates.

The settings scaling further reinforces this conclusion. At 1920x1080, going from Low to Medium reduces FPS from 69 to 46, a 33% drop. Low to High reduces it to 39 FPS, a 43% drop. Low to Ultra reduces it to 30 FPS, a 57% drop. These are substantial penalties for graphical quality increases, again pointing to the GPU as the primary bottleneck. The Arc B370's memory bandwidth is system dependent, and its 25 W TDP indicates a low-power integrated-class part, which aligns with the observed performance ceiling.

At all three resolutions, the CPU's role is secondary. The i7-12700K has more than enough single-thread and multi-thread capability for Rust's simulation and physics workloads, as evidenced by its PassMark single-thread score of 4013 and multi-thread score of 34404. The data suggests that even at 1080p Low, the CPU is not the limiting factor; the GPU simply cannot render frames fast enough to saturate the processor's capabilities.

Measured FPS Breakdown

3840x2160:

• High: average 16 FPS
• Medium: average 19 FPS, minimum 16 FPS, maximum 22 FPS
• Low: average 28 FPS
• Ultra: average 12 FPS

2560x1440:

• High: average 27 FPS
• Medium: average 32 FPS, minimum 27 FPS, maximum 37 FPS
• Low: average 48 FPS
• Ultra: average 20 FPS

1920x1080:

• High: average 39 FPS
• Medium: average 46 FPS, minimum 39 FPS, maximum 53 FPS
• Low: average 69 FPS
• Ultra: average 30 FPS

The medium preset data points are the only entries with recorded minimum and maximum values. At 3840x2160, the frame time variance is tight, with a 6 FPS spread between minimum and maximum. At 2560x1440, the spread widens to 10 FPS, and at 1920x1080 it reaches 14 FPS. This suggests that frame pacing becomes more consistent at higher resolutions, likely because the GPU is uniformly saturated. At 1080p, the GPU has occasional bursts of headroom that allow for higher peaks, but these are not sustained.

The average FPS figures show a linear relationship with resolution scaling. At Low settings, the progression is 69, 48, and 28 FPS for 1080p, 1440p, and 4K respectively. This roughly corresponds to the pixel count ratios: 1440p has 1.78 times the pixels of 1080p, and 4K has 2.25 times the pixels of 1440p. The FPS drops are close to these ratios, confirming that the render pipeline is scaling as expected for a GPU-limited workload.

The Verdict

This combination cannot run Rust at a playable level at 3840x2160 or 2560x1440 under any settings preset. The verdict data shows no playable settings for either resolution, meaning every configuration falls below 60 FPS. Even the best option at 1440p, Low at 48 FPS, misses the threshold by 12 FPS.

At 1920x1080, the system is marginally playable, but only on Low settings. The average FPS at this configuration is 69, which provides a 9 FPS cushion above the 60 FPS line. Medium, High, and Ultra all fail to reach the threshold, with averages of 46, 39, and 30 FPS respectively.

The overall picture is that the Intel Arc B370 is the decisive limiting factor. Its performance percentile of 5 among all GPUs places it near the bottom of the hardware pool, and its benchmark score of 1184 in 3DMark Steel Nomad DX12 confirms its low-end positioning. For users seeking a smooth Rust experience, this GPU is not sufficient beyond 1080p Low. The CPU, by contrast, is not a concern; the i7-12700K has ample headroom for this game's demands.

How This Combo Ranks

In the database's ranking of tested CPU and GPU combinations for Rust, this setup ranks 3437 out of 3723 combinations. This places it in the bottom 8% of all tested systems, reflecting the GPU's severe performance limitation. The rank is consistent with the measured FPS data: the system can barely manage 60 FPS at 1080p Low, and it fails entirely at higher resolutions.

The ranking is driven almost entirely by the GPU. The i7-12700K is a high-end processor, but the Arc B370's integrated-class performance drags the entire combination down. The data shows that this pairing is heavily imbalanced, with the CPU capable of far more than the GPU can deliver. Users considering this combination should be aware that the GPU will need to be upgraded to achieve playable performance at higher resolutions or settings.

Similar Performance Alternatives

Looking at the nearest rivals for the GPU, the Intel Arc B370 performs almost identically to several older discrete and mobile parts. The ATI Mobility Radeon HD 5570 scores 1186, a 0.2% difference from the Arc B370's 1184. The ATI Radeon HD 5770 scores 1190, and the AMD Radeon HD 7650M scores 1192, both within 0.7% of the Arc B370. The AMD FirePro M2000 scores 1168, which is 1.4% lower. Any of these GPUs would deliver essentially the same Rust performance as the Arc B370, meaning all would struggle to exceed 1080p Low at 60 FPS.

On the CPU side, the i7-12700K's nearest rivals are all within 0.4% of its average benchmark score. The Intel Core i5-13600T scores 35305, a 0.1% difference. The Intel Core i7-12700KF scores 35365, a 0.2% difference. The Intel Core i7-13700T scores 35403, a 0.3% difference, and the Intel Core 5 213PE scores 35428, a 0.4% difference. Swapping the i7-12700K for any of these processors would have a negligible impact on Rust performance, since the GPU is the bottleneck. The choice of CPU among these alternatives is effectively irrelevant for this game at this GPU level.
