Rust

The Intel Core i5-12400 paired with the Intel Arc B390 presents a sharply defined performance profile in Rust, one that is heavily constrained by the graphics solution. The data indicates a system that can handle the game at 1080p with reduced settings, but which falls short of a smooth experience at higher resolutions or more demanding presets. This analysis breaks down the recorded measurements to show exactly where this combo stands.

Measured FPS Breakdown

The measured frame rates for this combination span three resolutions and four settings presets, revealing a consistent and predictable pattern of performance. The Arc B390, with its integrated graphics architecture, is the primary limiter, and the numbers reflect its capabilities.

At 3840x2160 (4K), the results are uniformly below playable thresholds. With the Low preset, the average frame rate is 31 FPS. Moving to Medium drops the average to 21 FPS, with a minimum of 18 FPS and a maximum of 24 FPS. The High preset yields an average of 18 FPS, and the Ultra preset falls to an average of 13 FPS. None of these settings approach the 60 FPS playable threshold.

At 2560x1440 (1440p), performance improves but remains insufficient for smooth gameplay at standard settings. The Low preset records an average of 53 FPS, the highest of any setting at this resolution. Medium averages 35 FPS, with a minimum of 30 FPS and a maximum of 41 FPS. High drops to an average of 30 FPS, and Ultra falls to 23 FPS. While the Low preset is close, it still does not clear the 60 FPS bar.

At 1920x1080 (1080p), the combination finally finds a playable configuration. The Low preset achieves an average of 76 FPS, which is the only setting across all resolutions to exceed the 60 FPS playable threshold. The Medium preset averages 51 FPS, with a minimum of 44 FPS and a maximum of 59 FPS, placing it just below the target. High averages 43 FPS, and Ultra averages 33 FPS. The data clearly shows that 1080p Low is the sole viable option for this hardware.

CPU and GPU Roles

The benchmark results indicate a system where the GPU is the dominant performance bottleneck. The Intel Core i5-12400 is a 6-core, 12-thread processor with a boost clock of 4.40 GHz, and its benchmark scores (such as a Cinebench R23 multi-core score of 15989) suggest it has ample headroom for gaming. However, the Intel Arc B390 is an integrated graphics processor (IGP) with a 9th percentile ranking among all GPUs, which puts its performance in the lowest tier.

The evidence for the GPU bottleneck is visible in the scaling between resolutions. When moving from 1080p to 1440p at the Low preset, the average frame rate drops from 76 FPS to 53 FPS, a 30% reduction. Moving from 1440p to 4K at Low further reduces the average to 31 FPS, another 41% drop. This steep decline with increasing pixel count is a classic sign of a GPU-limited scenario. A CPU-bound system would show a much smaller frame rate difference across resolutions, as the processor's workload would remain relatively constant.

The same pattern holds across presets. At 1080p, increasing the settings from Low to Ultra reduces the average frame rate from 76 FPS to 33 FPS, a 57% decrease. This significant performance hit from raising graphical fidelity again points to the GPU's fill-rate and shading capabilities as the limiting factor. The CPU, with its strong multi-threaded performance, is not the constraint; it is the Arc B390's 1536 shading units and 24 ROPs that are unable to keep up with the demands of higher resolutions and more complex shaders.

The data suggests that the i5-12400 could support higher frame rates if paired with a more powerful discrete GPU. The processor's percentile rank of 72 among all CPUs indicates solid performance, far above the GPU's 9th percentile. This imbalance is the defining characteristic of this pairing: a capable processor held back by an entry-level graphics solution.

FAQ

The Verdict

Can this PC run Rust? The answer is conditional. Based on the recorded data, this combination can run the game, but only within a narrow range of settings. The verdict by resolution is clear:

At 3840x2160, the system is not playable. No settings preset achieves a frame rate close to 60 FPS, with the highest average being 31 FPS on Low.

At 2560x1440, the system is also not playable. The best result is 53 FPS on Low, which still falls short of the 60 FPS threshold.

At 1920x1080, the system is playable, but only with the Low preset. This configuration delivers an average of 76 FPS, which clears the playable threshold. The Medium preset, at 51 FPS average, will not provide a consistently smooth experience.

For users targeting a stable 60 FPS, this system is limited to 1080p with the lowest graphical settings. Any attempt to increase visual quality or resolution will result in frame rates that are below the acceptable threshold for smooth gameplay.

Similar Performance Alternatives

The nearest rivals for the Intel Arc B390 provide a context for its performance level. According to the database, the GPU's average benchmark score of 1482 is closely matched by several older, low-end discrete GPUs:

• The NVIDIA GeForce GT 520MX has an average score of 1463, which is 1.3% lower than the Arc B390.
• The NVIDIA GeForce 800M has an average score of 1460, which is 1.5% lower.
• The NVIDIA GeForce GT 625 OEM has an average score of 1446, which is 2.5% lower.
• The NVIDIA GeForce GT 710 has an average score of 1443, which is 2.7% lower.

These GPUs would likely produce very similar frame rates in Rust, meaning they would also be confined to 1080p Low settings for playable performance. The Arc B390 holds a slight edge over all of them, but the differences are minimal, within a 3% range.

On the CPU side, the Intel Core i5-12400's nearest rivals show that its processing power is in a much higher tier. Its average benchmark score of 18683 is nearly matched by:

• The AMD EPYC 7643, which scores 18697, a 0.1% difference.
• The Intel Core i7-1355U, which scores 18730, a 0.3% difference.
• The AMD Ryzen AI 5 330, which scores 18811, a 0.7% difference.
• The Intel Core i3-14100F, which scores 18519, a 0.9% difference.

These CPUs would all provide similar processor-level performance for Rust, but none of them would overcome the GPU bottleneck that defines this system's gaming capabilities.

How This Combo Ranks

In the database's overall rankings for Rust, this specific combination of the Intel Core i5-12400 and Intel Arc B390 holds a rank of 3312 out of 3723 tested combos. This places it in the bottom 11% of all systems, which is consistent with the measured frame rates. The low ranking is almost entirely attributable to the GPU's performance, as the CPU's score is above average. This rank indicates that the vast majority of other tested hardware combinations will deliver better frame rates in Rust, often at higher resolutions and with higher quality settings.

This position in the rankings underscores the fundamental imbalance of this pairing. While the i5-12400 is a competent processor, the Arc B390 is a severe limiting factor, dragging the overall gaming experience down to the lowest tier of the benchmark charts.

Best Settings per Resolution

The optimal settings for achieving a frame rate at or above the 60 FPS playable threshold are as follows:

• At 3840x2160: No settings are playable. The database records no playable settings for this resolution.
• At 2560x1440: No settings are playable. The database records no playable settings for this resolution.
• At 1920x1080: The Low preset is the most demanding setting that remains playable, with an average frame rate of 76 FPS. This is the only configuration across all tested resolutions and presets that meets the 60 FPS target.
