Rust

Intel Core i5-12400F and Intel Arc B370 is a combination that lands near the bottom of the database for Rust, with the recorded data showing a fundamental mismatch between the CPU's mid-range capability and the GPU's very low performance tier. The Arc B370 sits in the 5th percentile of all GPUs tested, and its only benchmark score (1184 in 3DMark Steel Nomad) places it alongside integrated and decade-old discrete parts. This pairing manages to clear the 60 FPS threshold at only one setting across all tested resolutions, and even that success is marginal. The following analysis breaks down the measured FPS data, ranking, and component roles to explain exactly where this system stands.

Measured FPS Breakdown

At 3840x2160, the results are uniformly below playable levels. The highest average FPS recorded is 28 at Low settings, which is less than half of the 60 FPS playable threshold. Medium settings produce an average of 19 FPS, with a minimum of 16 and a maximum of 22, showing tight but consistently low performance. High settings drop further to 16 FPS average, and Ultra bottoms out at 12 FPS. No resolution at 4K comes close to delivering a smooth experience, and the gap between Low and Ultra is a 16 FPS spread, indicating that the GPU is the limiting factor even at the lowest preset.

Moving to 2560x1440, the situation improves slightly but remains firmly in unplayable territory. Low settings deliver 48 FPS average, which is still 12 FPS short of the 60 FPS target. Medium settings average 32 FPS, with a minimum of 27 and a maximum of 37, a range that shows some variability but no hope of reaching playability. High settings average 27 FPS, and Ultra drops to 20 FPS. The scaling from Low to Ultra at this resolution is a 28 FPS drop, which is proportionally similar to 4K, suggesting the GPU is consistently saturated across these settings.

At 1920x1080, the only playable result appears. Low settings average 69 FPS, which clears the 60 FPS threshold by 9 FPS. Medium settings average 46 FPS, with a minimum of 39 and a maximum of 53, meaning even the maximum recorded frame time stays below the playable mark. High settings average 39 FPS, and Ultra averages 30 FPS. The difference between Low and Ultra at 1080p is 39 FPS, the largest spread across all resolutions, which indicates that the GPU's limited compute resources are heavily taxed by higher presets.

The data shows a clear pattern: each resolution step down from 4K to 1080p roughly doubles the average FPS at Low settings (28 to 48 to 69), while the higher presets improve less proportionally. This suggests that at 4K and 1440p, the GPU is completely overwhelmed, while at 1080p Low, it finally has enough headroom to approach a playable frame rate.

How This Combo Ranks

The combined rank for this CPU and GPU pairing in Rust is 3437 out of 3723 tested combinations, placing it in the bottom 8 percent of all configurations in the database. This is a very low standing, driven almost entirely by the GPU's performance class. The Arc B370's percentile rank of 5 means it outperforms only 5 percent of all GPUs recorded, a figure consistent with its 3DMark Steel Nomad score of 1184. The nearest GPU rivals in the database are the ATI Mobility Radeon HD 5570 (score 1186, 0.2 percent slower), ATI Radeon HD 5770 (score 1190, 0.5 percent slower), AMD Radeon HD 7650M (score 1192, 0.7 percent slower), and AMD FirePro M2000 (score 1168, 1.4 percent faster). These are all legacy or entry-level parts, confirming that the Arc B370 is not competitive with modern discrete GPUs.

The CPU, by contrast, is a much stronger component. The Intel Core i5-12400F ranks in the 73rd percentile of all CPUs, with an average benchmark score of 19039. Its nearest rivals are all within a fraction of a percent: AMD Ryzen 5 7535HS (score 19047, 0 percent delta), Intel Core 3 201E (score 19056, 0.1 percent faster), Intel Core i5-1335U (score 18982, 0.3 percent slower), and AMD EPYC 7773X (score 18979, 0.3 percent slower). This means the CPU is capable of feeding a much more powerful GPU, but the pairing with the Arc B370 severely limits overall game performance. The rank of 3437 out of 3723 reflects the GPU bottleneck, not the CPU's potential.

FAQ

Q: Can this PC run Rust at 1080p with playable frame rates?

Q: Does the combination rank well among tested systems?

A: No, it ranks 3437 out of 3723 combinations in the database for Rust. This places it in the bottom 8 percent, consistent with the GPU's very low performance percentile.

The Verdict

Based on the recorded data, this PC can run Rust at 1920x1080 with Low settings, achieving an average of 69 FPS. This is the only resolution and preset combination where the average FPS meets or exceeds the 60 FPS playable threshold. At 2560x1440, no preset reaches 60 FPS, with Low averaging 48 FPS and all higher presets falling below 33 FPS. At 3840x2160, the situation is worse, with Low averaging 28 FPS and Ultra at 12 FPS. The verdict is clear: this system is only viable for 1080p gaming on the lowest settings, and even then, the margin above 60 FPS is slim. For any higher resolution or preset, the performance is not playable according to the database's threshold.

Similar Performance Alternatives

For the GPU, the nearest rivals in the database are the ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, AMD Radeon HD 7650M, and AMD FirePro M2000. These parts have average scores within 1.4 percent of the Arc B370's 1184, meaning they would deliver nearly identical frame rates in Rust. A system using any of these GPUs with the same CPU would be expected to produce similar results, i.e., the same 69 FPS at 1080p Low and sub-60 FPS everywhere else.

For the CPU, the nearest rivals are the AMD Ryzen 5 7535HS, Intel Core 3 201E, Intel Core i5-1335U, and AMD EPYC 7773X. These processors have average scores within 0.3 percent of the i5-12400F's 19039, so swapping the CPU for any of these would have virtually no impact on Rust's frame rates, given that the GPU is the bottleneck. A system with any of these CPUs paired with a more powerful GPU would perform much better, but with the Arc B370, the CPU choice is nearly irrelevant.

Best Settings per Resolution

At 3840x2160, there is no preset that stays at or above 60 FPS. The highest average FPS is 28 at Low settings, which is the best possible result, but it is not playable. At 2560x1440, the same applies: no preset reaches 60 FPS, and Low at 48 FPS is the highest recorded average. At 1920x1080, the most demanding preset that stays at or above 60 FPS is Low, with an average of 69 FPS. Medium settings at 1080p average 46 FPS, which is below the threshold, so Low is the only choice for playable performance. The data shows that each resolution step down allows for the same relative improvement, but only 1080p Low crosses the line.

CPU and GPU Roles

The data shows a stark division of labor between the CPU and GPU in Rust. The Intel Core i5-12400F is a strong processor, ranking in the 73rd percentile of all CPUs, with an average benchmark score of 19039. Its nearest rivals, such as the AMD Ryzen 5 7535HS and Intel Core 3 201E, have nearly identical scores, indicating that this CPU is more than capable of handling the game's logic and physics. The GPU, however, is the limiting factor. The Intel Arc B370 ranks in the 5th percentile, and its score of 1184 is comparable to decade-old integrated graphics.

The scaling between resolutions and presets confirms this. At 4K, the average FPS ranges from 12 (Ultra) to 28 (Low), a 16 FPS spread. At 1440p, the range is 20 (Ultra) to 48 (Low), a 28 FPS spread. At 1080p, the range is 30 (Ultra) to 69 (Low), a 39 FPS spread. This increasing spread at lower resolutions is a classic sign of a GPU bottleneck: as resolution drops, the GPU has more headroom to respond to preset changes, but the overall performance is still capped by the GPU's low compute power. The CPU's role is to feed frames, and it does so without issue, but the GPU cannot process them fast enough.

At 4K and 1440p, the GPU is so overwhelmed that preset changes have relatively little impact, with only 16 to 28 FPS differences between Low and Ultra. At 1080p, the GPU is still the bottleneck, but it has enough headroom to show a larger 39 FPS difference between presets. If the CPU were the limiting factor, the FPS would remain roughly constant across resolutions, but the data shows a clear increase as resolution drops, which points entirely to the GPU. For this game, the Arc B370 is the component that determines whether the system is playable, and it only allows for 1080p Low.
