Rust

Measured FPS Breakdown

The recorded data for Rust on this AMD Ryzen 9 5900X with Intel Arc B370 combination shows a clear picture: performance scales predictably with resolution and preset, but the GPU becomes the limiting factor early. At 3840x2160, the results are uniformly poor. The High preset averages 16 FPS, Medium averages 19 FPS with a minimum of 16 and maximum of 22, Low averages 28 FPS, and Ultra drops to 12 FPS. None of these numbers approach playable territory, and the spread between presets is narrow, indicating the GPU is saturated even at the lowest settings.

Moving to 2560x1440, the situation improves but remains far from smooth. Low settings produce an average of 48 FPS, which is the only setting at this resolution that comes close to the 60 FPS threshold. High averages 27 FPS, Medium averages 32 FPS with a minimum of 27 and maximum of 37, and Ultra falls to 20 FPS. The jump from Low to Medium is only 16 FPS on average, which suggests that the GPU’s limited shading and rasterization capabilities are the primary bottleneck rather than CPU overhead.

At 1920x1080, the data finally shows a playable configuration. Low settings deliver an average of 69 FPS, which clears the 60 FPS threshold by a comfortable margin. Medium settings average 46 FPS with a minimum of 39 and maximum of 53, High averages 39 FPS, and Ultra averages 30 FPS. The gap between Low and Medium is 23 FPS, which is larger than the gap between Medium and High (7 FPS) or High and Ultra (9 FPS). This indicates that the Low preset avoids certain GPU-intensive effects that disproportionately impact this particular graphics solution.

The min/max data is only recorded for Medium settings at each resolution. At 1080p Medium, the range is 39 to 53 FPS, meaning even the peak frame rate does not hit 60 FPS. At 1440p Medium, the range is 27 to 37 FPS, and at 4K Medium, it is 16 to 22 FPS. These ranges are tight, which points to consistent frame pacing rather than sudden spikes or drops. However, consistency at low frame rates does not make up for the overall lack of headroom.

Best Settings per Resolution

For 3840x2160, no preset achieves 60 FPS. The best recorded average is 28 FPS at Low settings, which is less than half of the playable threshold. The database’s verdict confirms this: there are no playable settings at 4K for this combination. If a user must run at this resolution, Low is the only option that offers any semblance of responsiveness, but the experience will be severely compromised.

At 2560x1440, the same conclusion applies. No preset reaches 60 FPS. The highest average is 48 FPS at Low settings, which is 12 FPS short of the threshold. Medium, High, and Ultra all fall further behind, with averages of 32, 27, and 20 FPS respectively. The verdict lists no playable settings for 1440p, so users should not expect a smooth experience at this resolution regardless of quality adjustments.

At 1920x1080, the Low preset is the only configuration that clears 60 FPS, with an average of 69 FPS. This is the sole playable setting across all resolutions and presets in the measured data. Medium, High, and Ultra all fail to reach the threshold, averaging 46, 39, and 30 FPS respectively. The recommendation is clear: if you want to play Rust on this hardware, 1080p Low is the target. The 9 FPS margin above 60 FPS provides some breathing room for less demanding scenes, but the minimum frame rate at Medium (39 FPS) suggests that even Low may dip during heavy load, though no min data is recorded for Low to confirm this.

FAQ

Q: Can this PC run Rust at 4K resolution?

A: No. The best average FPS at 3840x2160 is 28 FPS on Low settings, which is far below the 60 FPS playable threshold. Medium averages 19 FPS, High averages 16 FPS, and Ultra averages 12 FPS. The database records no playable settings at this resolution.

Q: What is the highest playable preset at 1080p?

A: The only preset that achieves 60 FPS or higher at 1920x1080 is Low, with an average of 69 FPS. Medium averages 46 FPS, High averages 39 FPS, and Ultra averages 30 FPS, so none of those are playable by the 60 FPS standard.

Q: How does the Intel Arc B370 compare to its nearest GPU rivals?

A: The Arc B370’s average benchmark score is 1184. Its nearest rival is the ATI Mobility Radeon HD 5570 with a score of 1186, which is 0.2% faster. The ATI Radeon HD 5770 scores 1190 (0.5% faster), and the AMD Radeon HD 7650M scores 1192 (0.7% faster). The AMD FirePro M2000 scores 1168, which is 1.4% slower. This places the Arc B370 at the 5th percentile of all GPUs, indicating very low relative performance.

Q: Why is the frame rate so similar between Medium and High settings?

A: At 1080p, Medium averages 46 FPS while High averages 39 FPS, a difference of only 7 FPS. At 1440p, the gap is 5 FPS (32 vs 27), and at 4K it is 3 FPS (19 vs 16). This narrow scaling suggests the GPU is already maxed out, so raising settings from Medium to High adds only marginal visual load but the hardware cannot translate that into meaningful extra work.

Q: What does the combo rank tell us about this system?

A: This CPU and GPU combination ranks 3437 out of 3723 tested combos in Rust. That places it in the bottom 8% of all recorded configurations, which is consistent with the measured FPS results showing only 1080p Low as playable.

Q: Is the CPU or GPU the bottleneck in Rust?

A: The data indicates the GPU is the limiting factor. The Arc B370 sits at the 5th percentile of all GPUs, while the Ryzen 9 5900X is at the 87th percentile of all CPUs. The CPU’s nearest rivals include the Intel Core Ultra 7 366H (0.3% faster) and the Intel Core i7-14650HX (0.5% slower), showing it is a strong performer. The GPU’s nearest rivals are over a decade old, which explains why frame rates drop so sharply when resolution increases.

The Verdict

Can this PC run Rust? The answer depends entirely on resolution. At 3840x2160, absolutely not. The best case is 28 FPS on Low, which is unplayable for a survival game that requires quick reactions. At 2560x1440, still no. The Low preset averages 48 FPS, which is 12 FPS short of the 60 FPS threshold, and every other preset falls even further behind.

At 1920x1080, the answer is a qualified yes. The Low preset achieves an average of 69 FPS, clearing the playable threshold by 9 FPS. This is the only configuration in the entire dataset that meets the 60 FPS standard. Medium, High, and Ultra all fail, with averages of 46, 39, and 30 FPS respectively.

The verdict from the database is unambiguous: playable settings exist only at 1080p, and only on Low. The 69 FPS average provides enough headroom for most gameplay, but users should be aware that the minimum frame rate at Medium (39 FPS) hints that Low may also experience dips in dense scenes with many players or complex bases. This is not a system for high-refresh monitors or for pushing visual quality. It is a configuration that can run Rust at entry-level settings, nothing more.

CPU and GPU Roles

The division of labor between the AMD Ryzen 9 5900X and the Intel Arc B370 is stark. The CPU is a high-end desktop processor from 2020 with 12 cores and 24 threads, a 64 MB L3 cache, and a boost clock of 4.80 GHz. It sits at the 87th percentile of all CPUs, with an average benchmark score of 41376. Its nearest rivals include the Intel Core Ultra 7 366H (0.3% faster) and the Intel Core i7-14650HX (0.5% slower), both modern laptop-class chips. This is not a CPU that will hold back a game like Rust, which is known to be single-thread sensitive.

The GPU, on the other hand, is an integrated-class part based on Intel’s Xe3-LPG architecture with 1280 shading units, 40 TMUs, and 20 ROPs. Its average benchmark score is 1184, placing it at the 5th percentile of all GPUs. The nearest rivals are the ATI Mobility Radeon HD 5570 and the ATI Radeon HD 5770, both from around 2010. This is the clearest possible signal that the GPU is the bottleneck.

The scaling data confirms this. Going from 1080p to 1440p at Low settings drops the average from 69 to 48 FPS, a 30% reduction. Going from 1440p to 4K at Low drops from 48 to 28 FPS, another 42% reduction. These are GPU-bound scaling patterns. If the CPU were the limiting factor, resolution changes would have a much smaller impact on frame rates. Similarly, at 1080p, the difference between Low and Ultra is 39 FPS (69 to 30), which is a 57% penalty for maxing out settings. This is consistent with a GPU that has only 6.144 TFLOPS of FP32 performance and a pixel rate of 48.00 GPixel/s.

The CPU’s role becomes more apparent when looking at the lack of frame time variance. The recorded min/max values for Medium at all three resolutions are tight, with spreads of 14 FPS at 1080p (39 to 53), 10 FPS at 1440p (27 to 37), and 6 FPS at 4K (16 to 22). This suggests the CPU is feeding frames consistently without stutters or hitches. The problem is not frame pacing, it is raw throughput. The GPU simply cannot render enough frames to reach 60 FPS except at the lowest settings and resolution.

For users considering an upgrade path, the data points to the GPU as the component to replace. The Ryzen 9 5900X has enough headroom to drive a much faster graphics card, and the 87th percentile CPU ranking shows it is not the weak link. Swapping the Arc B370 for something with even double the average benchmark score would likely unlock 60 FPS at 1440p, and possibly higher presets at 1080p.

How This Combo Ranks

The AMD Ryzen 9 5900X and Intel Arc B370 combination ranks 3437 out of 3723 tested combos in Rust. That puts it in the bottom 7.7% of all systems tested, which is a poor result by any measure. The rank is driven overwhelmingly by the GPU, as the CPU’s individual ranking is strong while the GPU’s is near the bottom of the database.

To put this in context, the GPU’s nearest rivals are all over a decade old. The ATI Mobility Radeon HD 5570, ATI Radeon HD 5770, and AMD Radeon HD 7650M all score within 1% of the Arc B370. These are cards from the era when 1080p gaming was just becoming mainstream, and they were mid-range or entry-level even then. The CPU, meanwhile, is competing with modern laptop processors like the Intel Core Ultra 7 366H and Intel Core i7-14650HX, and it holds its own against them.

The practical implication is that this combo is severely imbalanced. The CPU has far more capability than the GPU can utilize. In Rust, which is a CPU-intensive game due to its large persistent world and many entity interactions, this imbalance does not help because the GPU still becomes the limiting factor at any resolution above 1080p Low. The combo rank of 3437 reflects this reality: the system can run the game, but only at the lowest possible quality settings, and it will not handle future updates or more demanding presets gracefully.

For anyone building a system for Rust, this rank serves as a warning. A CPU of this caliber deserves a GPU that is at least in the 50th percentile or higher. The Arc B370, with its 5th percentile ranking, is holding back the entire system. The measured FPS data shows that even the CPU’s strong single-threaded performance (3dmark single thread score of 941, Cinebench R23 single core of 1527) cannot compensate for the GPU’s lack of fill rate and shading power. The result is a system that technically runs Rust, but only in the most minimal sense of the word.
