Q: What is the minimum FPS recorded in any tested configuration?

A: The only configurations with recorded minimum FPS values are the Medium settings at each resolution. At 4K Medium, the minimum is 18 FPS; at 1440p Medium, it is 30 FPS; and at 1080p Medium, it is 44 FPS.

GPU Role

The Intel Arc B390 is an integrated graphics solution based on the Xe3-LPG architecture, built on Intel’s 3 nm process. It has a base clock of 300 MHz and a boost clock of 2500 MHz, with a TDP of 80 W. The GPU’s memory is entirely system-shared, meaning its bandwidth is dependent on the host system’s DDR4 memory configuration. With 1536 shading units, 48 texture mapping units, and 24 raster output units, the Arc B390 is fundamentally a low-power integrated part.

Benchmark results confirm this weak positioning. The Arc B390 scores only 1482 in the 3DMark Steel Nomad DX12 test, placing it at the 9th percentile of all GPUs. Its nearest rivals are ancient discrete parts: the NVIDIA GeForce GT 520MX, which it beats by 1.3%, and the NVIDIA GeForce GT 710, which it outperforms by 2.7%. This context is crucial for understanding the Rust results, as the GPU is clearly the primary limiting factor in this system.

The GPU’s impact on Rust is dramatic. At 4K Ultra settings, the system manages only 13 FPS, which is unplayable by any standard. Even at 1080p Low, the best-case scenario, the system reaches 76 FPS, but this is the only configuration that breaks the 60 FPS threshold. The data suggests that the Arc B390’s 7.680 TFLOPS of FP32 performance is simply insufficient for Rust’s rendering demands at higher resolutions and settings. The 60.00 GPixel/s pixel rate and 120.0 GTexel/s texture rate are not competitive for a game that requires sustained fill-rate performance in open-world environments.

CPU Role

The AMD Ryzen 5 4600G is a 6-core, 12-thread processor from the 4000 series, based on the Zen 2 architecture (codename Renoir) on a 7 nm TSMC process. It has a base clock of 3.70 GHz and a boost clock of 4.20 GHz, with a TDP of 65 W. The CPU features 8 MB of shared L3 cache and supports dual-channel DDR4 memory with a bandwidth of 51.2 GB/s.

In synthetic benchmarks, the 4600G shows respectable multi-threaded performance. It scores 13593 in Cinebench R23 multi-core and 5709 in Cinebench R20 multi-core. However, single-thread performance is weaker, with a Cinebench R23 single-core score of 1919 and a Geekbench single-core score of 1460. The CPU sits at the 71st percentile among all CPUs, with an average benchmark score of 17507.

The CPU’s nearest rivals are all comparable or slightly inferior in average score. The AMD Ryzen 3 PRO 5355GE is essentially tied at 0.1% faster, while the Intel Core 7 150U is 0.6% faster. The AMD Ryzen 3 8300GE and Intel Core i3-14100T are 0.6% and 0.8% faster respectively. This means the 4600G is not a standout performer, but it is also not a weak link that would severely bottleneck a more powerful GPU.

In Rust, the CPU’s role is secondary to the GPU. The measured FPS data shows that resolution scaling has a massive impact on performance, which is characteristic of GPU-bound scenarios. However, the CPU’s 12 threads and 4.20 GHz boost clock are likely sufficient to feed the Arc B390 in most situations. The data does not show a scenario where the CPU is clearly the limiting factor, as frame rates drop sharply with increased resolution, which taxes the GPU more than the CPU.

Settings Recommendations

Given the extreme performance limitations of this combo, the settings recommendations are straightforward. The only configuration that provides a consistently playable experience is 1920x1080 with Low settings, which delivers an average of 76 FPS. This should be the default recommendation for any user of this system.

The data shows a clear progression of performance degradation at 1080p. Medium settings drop to 51 FPS, which is playable but not smooth, with a minimum of 44 FPS that could cause noticeable stuttering. High settings fall to 43 FPS, and Ultra plummets to 33 FPS, both of which are below the threshold for comfortable gameplay in a fast-paced survival game like Rust.

At 1440p, only Low settings (53 FPS) approach playability, but the minimum FPS is not recorded, leaving uncertainty. Medium at 1440p averages 35 FPS with a minimum of 30 FPS, which is borderline. At 4K, no settings are viable, with the best case being Low at 31 FPS and the worst being Ultra at 13 FPS.

The recommendation is clear: use 1080p Low for the best experience. If visual fidelity is a priority, 1080p Medium at 51 FPS is the only other option that maintains an average above 50 FPS. Anything higher in resolution or settings will result in a sub-30 FPS experience that is detrimental to gameplay in a survival title where quick reactions are essential.

How This Combo Ranks

This combo ranks 2601st out of 2953 tested combos in Rust, placing it in the bottom 12% of all configurations. This low ranking is driven almost entirely by the GPU, which is at the 9th percentile globally. The CPU is in the 71st percentile, so the pairing represents a significant mismatch in capability.

The ranking suggests that this system is not suitable for Rust at any settings above minimal. The data shows that even at the lowest resolution and settings, the system is only marginally above the 60 FPS threshold, and any increase in graphical load pushes it into unplayable territory. The combo’s position in the bottom 12% indicates that the vast majority of tested systems can handle Rust better, likely because they use discrete GPUs.

The Arc B390’s integrated nature is the fundamental issue. Compared to its nearest GPU rivals, which are all over a decade old discrete parts, the Arc B390 is competitive, but those rivals are not capable of running modern games at playable frame rates either. The combo rank reflects the reality that this is an entry-level integrated solution being asked to run a demanding open-world game.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of this combo’s capabilities across resolutions and settings.

At 3840x2160 (4K), the results are uniformly poor. Low settings achieve an average of 31 FPS. Medium settings drop to 21 FPS, with a minimum of 18 FPS and a maximum of 24 FPS. High settings reach 18 FPS, while Ultra falls to 13 FPS. No 4K configuration is playable.

At 2560x1440 (1440p), the situation improves slightly. Low settings average 53 FPS. Medium settings average 35 FPS, with a minimum of 30 FPS and a maximum of 41 FPS. High settings drop to 30 FPS, and Ultra falls to 23 FPS. Only Low settings approach playability.

At 1920x1080 (1080p), the best results are achieved. Low settings average 76 FPS. Medium settings average 51 FPS, with a minimum of 44 FPS and a maximum of 59 FPS. High settings reach 43 FPS, and Ultra drops to 33 FPS. This is the only resolution where Low settings provide a smooth experience.

The data reveals a consistent pattern: performance scales linearly with resolution and settings. The gap between Low and Ultra at each resolution is significant, with Ultra averaging roughly 43-58% of the Low setting’s FPS across all resolutions.

Resolution Scaling

The performance drop from 1080p to 4K is severe and reveals the GPU-bound nature of this system. At Low settings, the average FPS drops from 76 at 1080p to 53 at 1440p (a 30.3% decrease) and then to 31 at 4K (a 59.2% decrease from 1080p). This scaling is not linear, indicating that the GPU becomes increasingly overwhelmed at higher resolutions.

At Medium settings, the drop is similar: from 51 FPS at 1080p to 35 FPS at 1440p (a 31.4% decrease) and 21 FPS at 4K (a 58.8% decrease). The minimum FPS also scales, from 44 at 1080p to 30 at 1440p and 18 at 4K.

This scaling pattern is a classic sign of a GPU bottleneck. If the CPU were the limiting factor, the FPS would remain relatively constant across resolutions. Instead, the sharp drops indicate that the Arc B390’s rendering capabilities are being saturated. The 4K results, which are below 32 FPS in all settings, suggest that the GPU’s fill rate and memory bandwidth (which is system-shared and dependent on DDR4) are insufficient for Rust’s high-resolution textures and geometry.

The data implies that the limiting component is unambiguously the GPU. The CPU’s 71st percentile ranking and 12 threads are more than adequate for Rust’s CPU demands, but the GPU’s 9th percentile ranking and integrated architecture cannot keep up. Any user of this system should prioritize upgrading to a discrete GPU, as the CPU has headroom to support a significantly more powerful graphics card.
