FAQ

Q: What is the best playable setting for this PC in Rust at 1920x1080?

A: At 1920x1080, the Low preset is the only setting that stays at or above 60 FPS, delivering an average of 76 FPS. The Medium preset drops to 51 FPS, High to 43 FPS, and Ultra to 33 FPS.

Q: Can this combo handle Rust at 2560x1440?

A: No. At 2560x1440, none of the tested presets reach 60 FPS. The closest is Low at 53 FPS, followed by Medium at 35 FPS, High at 30 FPS, and Ultra at 23 FPS.

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

A: The Arc B390's average benchmark score is 1482. It sits 1.3% above the NVIDIA GeForce GT 520MX (score 1463), 1.5% above the GeForce 800M (score 1460), 2.5% above the GT 625 OEM (score 1446), and 2.7% above the GT 710 (score 1443). These are very close margins, indicating near-identical raw performance.

Q: What is the CPU's standing relative to other processors?

A: The AMD Ryzen 5 7600 scores at the 78th percentile among all CPUs. Its average benchmark score is 26324. It is 0.2% ahead of the Ryzen 9 6900HX (score 26274), 0.4% ahead of the Core i9-11900KF (score 26212), 0.5% ahead of the Ryzen 5 8540U (score 26187), and 0.3% behind the Ryzen 7 7435HS (score 26402).

Q: What is the highest FPS recorded across all resolutions and settings?

A: The highest average FPS is 76, achieved at 1920x1080 with Low settings. The maximum FPS recorded in any measurement is 59, which is the max value at 1920x1080 Medium settings.

Q: Does the GPU's percentile ranking suggest it is a strong performer?

A: The Intel Arc B390 ranks at the 9th percentile among all GPUs, which is very low. Its nearest rivals are all older NVIDIA entry-level parts, and in Rust the measured frame rates confirm this weak standing, as even at 1080p Low it only reaches 76 FPS.

Best Settings per Resolution

3840x2160 (4K): No preset reaches 60 FPS. The highest average is 31 FPS at Low, followed by 21 FPS at Medium, 18 FPS at High, and 13 FPS at Ultra. Even the Low preset falls far below the playable threshold, so this resolution is not viable for smooth gameplay.

2560x1440 (1440p): No preset reaches 60 FPS. The Low preset delivers 53 FPS, which is the best result, but it still misses the 60 FPS target. Medium yields 35 FPS, High yields 30 FPS, and Ultra yields 23 FPS. The gap between Low and the next step is substantial, indicating a steep performance cliff as settings increase.

1920x1080 (1080p): The Low preset is the only playable option, delivering 76 FPS average. This is the most demanding preset that stays at or above 60 FPS. Medium drops to 51 FPS, High to 43 FPS, and Ultra to 33 FPS. For a consistent 60+ FPS experience, Low is the required setting.

Similar Performance Alternatives

CPU side: The Ryzen 5 7600's nearest rivals are all within a half-percent of its average score. The AMD Ryzen 9 6900HX (0.2% faster) and Intel Core i9-11900KF (0.4% faster) would behave nearly identically in CPU-bound scenarios. The AMD Ryzen 7 7435HS is 0.3% faster, and the AMD Ryzen 5 8540U is 0.5% slower. These deltas are so small that in real-world Rust gameplay, frame timing differences would be imperceptible.

GPU side: The Intel Arc B390's nearest rivals are dramatically older and weaker parts. The NVIDIA GeForce GT 520MX is 1.3% slower, the GeForce 800M is 1.5% slower, the GT 625 OEM is 2.5% slower, and the GT 710 is 2.7% slower. All four GPUs fall within a 3% band of the Arc B390's score, meaning a system with any of these GPUs would produce nearly identical frame rates in Rust, assuming the same CPU and settings.

Combined perspective: Since the GPU is the clear bottleneck (the CPU sits at the 78th percentile while the GPU sits at the 9th), swapping the Ryzen 5 7600 for any of its near-equal rivals would barely change the measured FPS. The recorded frame rates are almost entirely dictated by the Arc B390's low-end capabilities.

The Verdict

This PC can run Rust, but only at 1920x1080 with the Low preset. The recorded data shows an average of 76 FPS at that setting, which clears the 60 FPS playable threshold. No other combination of resolution and settings reaches 60 FPS.

At 2560x1440, the best result is 53 FPS on Low, which is below the threshold. At 3840x2160, the best result is 31 FPS on Low, which is far below playable. The verdict by resolution confirms this: only 1920x1080 has a playable setting (Low), with an average of 76 FPS. Both higher resolutions have no playable settings at all.

The pattern is consistent: this system is heavily GPU-limited, and the Arc B390's performance level is simply too low for anything beyond 1080p Low in Rust. Users who want higher settings or higher resolutions would need a much stronger GPU, as the CPU has ample headroom.

CPU and GPU Roles

The data shows a clear division of labor. At 1920x1080, the CPU is more than sufficient, as demonstrated by the 76 FPS result on Low. The Ryzen 5 7600's 78th percentile ranking and strong multi-threaded scores (Cinebench R23 multi-core 12735, Geekbench multi-core 13413) indicate it can handle Rust's simulation and networking loads without becoming the limiting factor.

The GPU takes over as the dominant constraint at every resolution. The Arc B390's 9th percentile ranking and its nearest rivals (all legacy entry-level GPUs) tell the story. As resolution increases from 1080p to 1440p to 4K, the average FPS on Low drops from 76 to 53 to 31, a decline of 30% and then another 41%. This steep scaling is characteristic of a GPU that runs out of fill rate and shading capacity quickly.

Within each resolution, the settings scaling also points to GPU dominance. At 1080p, going from Low to Medium drops FPS from 76 to 51 (a 33% reduction), and from Medium to High drops to 43 (a 16% reduction). At 1440p, Low to Medium drops from 53 to 35 (a 34% reduction). These consistent drops across settings indicate that the GPU is saturated even at Low settings, and any increase in pixel work or shading load directly cuts frame rates.

The CPU's role is secondary. At 1080p Low, the CPU is likely not fully utilized, but at higher resolutions the GPU bottleneck becomes so severe that CPU performance is irrelevant. The recorded data shows no scenario where the CPU's capabilities are stretched, and given its near-tie with the Ryzen 9 6900HX and Core i9-11900KF, any of those CPUs would produce nearly identical results.

How This Combo Ranks

In the database of tested CPU and GPU combinations for Rust, this pairing ranks 3312 out of 3723 combos. That places it in the bottom 11% of all tested systems. The rank reflects the GPU's severe limitation, as the CPU alone would rank much higher.

The combination of a high-end CPU (78th percentile) with a bottom-tier GPU (9th percentile) creates a heavily imbalanced system. The CPU contributes little to the final ranking because the GPU caps performance so low. In Rust, which is known for being CPU-intensive in server-side simulation, this imbalance still does not rescue the frame rates, because the GPU cannot keep up with even the simplest rendering tasks.

For context, combos ranked near 3312 would typically feature similarly weak GPUs paired with mid-range or better CPUs. The measured FPS data confirms that this combo's ranking is driven almost entirely by the Arc B390's performance ceiling.

Measured FPS Breakdown

3840x2160 (4K):

• Low: average 31 FPS, no min/max recorded
• Medium: average 21 FPS, min 18 FPS, max 24 FPS
• High: average 18 FPS, no min/max recorded
• Ultra: average 13 FPS, no min/max recorded

2560x1440 (1440p):

• Low: average 53 FPS, no min/max recorded
• Medium: average 35 FPS, min 30 FPS, max 41 FPS
• High: average 30 FPS, no min/max recorded
• Ultra: average 23 FPS, no min/max recorded

1920x1080 (1080p):

• Low: average 76 FPS, no min/max recorded
• Medium: average 51 FPS, min 44 FPS, max 59 FPS
• High: average 43 FPS, no min/max recorded
• Ultra: average 33 FPS, no min/max recorded

The Medium preset is the only one with recorded min/max values across all resolutions. At 1080p Medium, the min of 44 FPS and max of 59 FPS show that even the best-case frame rate stays below 60. At 1440p Medium, the range is 30 to 41 FPS. At 4K Medium, the range is 18 to 24 FPS. These ranges indicate significant frame time variance, but the averages are consistently low.

The step from Low to Medium is the largest performance penalty at every resolution, suggesting that Medium introduces rendering features (likely ambient occlusion, shadows, or texture quality) that disproportionately burden the Arc B390. The gap from Medium to High is smaller, and from High to Ultra is smaller still, indicating diminishing returns in visual quality relative to the FPS cost at the high end.
