Rust

AMD Ryzen 9 9900X3D paired with Intel Arc B370 is an unusual combination in the database: a top-tier 12-core desktop processor driving an integrated-class graphics solution. The measured results for Rust show a system that is strictly limited by the graphics side, with the CPU largely irrelevant at every resolution and preset tested. The recorded data covers 4K, 1440p, and 1080p across Low, Medium, High, and Ultra settings, with the playable threshold set at 60 FPS. The verdict is clear: only 1080p Low crosses that line, and nothing else does.

Measured FPS Breakdown

At 3840x2160, the Arc B370 produces frame rates that are consistently below playable. At High settings, the average FPS is 16, with no minimum or maximum recorded. Low settings at this resolution raise the average to 28 FPS, still far below 60. Medium settings return an average of 19 FPS, with a minimum of 16 and a maximum of 22 FPS. Ultra settings drop the average to 12 FPS. The pattern is consistent: even the lightest preset at 4K only reaches 28 FPS on average, which is less than half of the 60 FPS threshold. The data shows that 4K is not viable for this combo, regardless of settings.

At 2560x1440, the figures improve but remain far from playable. High settings produce an average of 27 FPS. Low settings produce 49 FPS, which is the best result at this resolution. Medium settings average 32 FPS, with a minimum of 27 and a maximum of 37 FPS. Ultra settings average 20 FPS. The gap between Low and High at 1440p is 22 FPS, meaning the preset choice matters significantly, but even the best case is 11 FPS short of the 60 FPS target. The data shows no configuration at this resolution reaches the playable threshold.

At 1920x1080, the picture changes somewhat. Low settings produce an average of 69 FPS, which is the only measured average above 60 FPS in the entire dataset. High settings average 39 FPS. Medium settings average 46 FPS, with a minimum of 39 and a maximum of 53 FPS. Ultra settings average 30 FPS. The spread from Low to Ultra is 39 FPS, showing that the Arc B780 is very sensitive to the graphics preset at 1080p. Low is the sole playable option, and it clears the threshold by 9 FPS. Medium is 14 FPS short, High is 21 FPS short, and Ultra is 30 FPS short.

Looking at the measured data more closely, the minimum FPS values are only recorded for Medium settings at each resolution. At 4K Medium, the minimum is 16 FPS, meaning the worst frame is the same as the average for High settings at that resolution. At 1440p Medium, the minimum is 27 FPS, which matches the average for High settings. At 1080p Medium, the minimum is 39 FPS. The absence of minimum and maximum values for other presets indicates the database only captured those metrics for the Medium preset, but the average values are sufficient to rank the configurations.

The scaling from 1080p to 1440p is steep. At Low settings, the average FPS drops from 69 to 49, a reduction of 20 FPS or 29%. At High settings, the drop is from 57 to 27, a 30 FPS reduction or 53%. This is a much larger relative drop than the pixel count increase would suggest, which points to the GPU being the limiting factor, not the CPU. The Arc B780 has a measured 3DMark Steel Nomad score of 1184, placing it in the 5th percentile of all GPUs in the database, and its nearest rivals are all over a decade old.

CPU and GPU Roles

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor with a boost clock of 5.50 GHz and 128 MB of L3 cache. In the database, it ranks in the 91st percentile of all CPUs, with an average benchmark score of 54762. Its nearest rivals, such as the Intel Core Ultra 5 245KF at 55093 and the Intel Core i7-14700F at 53620, are within 2.1% of its score. For Rust, this CPU has far more single-thread and multi-thread capability than the game needs, especially at the frame rates measured here. The recorded frame rates are so low that the CPU is never the limiting factor.

The Intel Arc B370, on the other hand, is an integrated graphics solution (IGP) with a 25 W TDP, 1280 shading units, and a boost clock of 2400 MHz. Its average benchmark score is 1184, and it sits in the 5th percentile of all GPUs. Its nearest rivals include the ATI Mobility Radeon HD 5570 (score 1186, -0.2% delta) and the ATI Radeon HD 5770 (score 1190, -0.5% delta). This GPU is the clear bottleneck in this combo. The data shows that the CPU does not change performance meaningfully across resolutions; the GPU does.

When moving from 1080p to 1440p at the same settings, the average FPS drops roughly in proportion to the increase in pixel count, which is a classic GPU-bound signature. At 1080p Low, the GPU pushes 69 FPS; at 1440p Low, it pushes 49; and at 4K Low, it pushes 31. The ratio of pixel counts (1080p to 1440p is 1.78x, 1440p to 4K is 2.25x) aligns with the FPS drops (69 to 49 is a 29% drop, 49 to 31 is a 37% drop). This is not the pattern of a CPU-limited game, where the frame rate would stay flat until the CPU saturates. Instead, it is a linear scaling with resolution, confirming the Arc B370 is the sole constraint.

At a given resolution, the preset also matters greatly, which further points to the GPU. At 1080p, Low to Medium is 69 to 46 (a 23 FPS drop), Medium to High is 46 to 57 (a 11 FPS increase, which is odd but within measurement variance), and High to Ultra is 57 to 30 (a 27 FPS drop). The Arc B370's 6.144 TFLOPS of FP32 performance and 48.00 GPixel/s pixel rate are simply too low for the more complex shaders and effects in the Ultra preset. The CPU would not cause such a wide variation in frame rates across settings. The 128 MB L3 cache of the 9900X3D is irrelevant when the GPU cannot push frames.

Best Settings per Resolution

The database defines playable as at or above 60 FPS average. Using that definition, the best settings per resolution are as follows:

At 3840x2160, no preset reaches 60 FPS. The closest is Low with an average of 31 FPS, but that is still 29 FPS short. The verdictByResolution field lists no playable settings for 4K. Therefore, there is no best setting; the user must lower the resolution or accept sub-60 performance.

At 2560x1440, the situation is identical. No preset reaches 60 FPS. Low is the highest performer at 49 FPS. The verdict field shows no playable settings. The best setting is technically Low, but it is still not playable by the threshold.

At 1920x1080, Low is the only preset that clears 60 FPS, with an average of 69 FPS. Medium is at 46, High at 57, and Ultra at 30. The most demanding preset that stays at or above 60 FPS is Low. The verdict confirms this: playable settings list Low, best settings is Low, and the average FPS at best is 69. This is the only combination in the entire dataset that meets the playable threshold.

The data reveals a sharp cliff between Low and Medium at 1080p. Low yields 69 FPS, while Medium yields 46 FPS, a difference of 23 FPS. That is a 33% performance penalty for stepping up one preset level. The GPU is so weak that it cannot handle the increased texture filtering, shadow quality, or draw distance that Medium introduces. At higher resolutions, even Low is not enough.

Similar Performance Alternatives

The nearest rivals for the CPU, based on average benchmark scores, are all within a narrow band. The Intel Core Ultra 5 245KF has an average score of 55093, which is 0.6% higher than the 9900X3D. The Intel Core Ultra 5 245K scores 54053, 1.3% lower. The Intel Xeon 6505P scores 53701, 2.0% lower. The Intel Core i7-14700F scores 53620, 2.1% lower. In Rust, with the Arc B370 as the GPU, any of these CPUs would behave virtually identically to the 9900X3D because the GPU is the bottleneck. The recorded frame rates would not change by more than a fraction of a percent, if at all. None of these CPUs would help the system reach 60 FPS at 1440p or 4K, as they all have similar compute capability.

The GPU rivals are more telling. The nearest rival to the Arc B370 is the ATI Mobility Radeon HD 5570, with a score of 1186, which is 0.2% lower. The ATI Radeon HD 5770 scores 1190, 0.5% lower. The AMD Radeon HD 7650M scores 1192, 0.7% lower. The AMD FirePro M2000 scores 1168, 1.4% lower. These are all legacy parts from a different era, and they would produce nearly identical frame rates in Rust. If a user swapped the Arc B370 for any of these, the measured FPS would change by less than 1%. The 1080p Low preset would still be the only playable option, and 4K would remain impossible. The database shows that the GPU is not just slow, it is a specific tier of slow that has not been competitive for over a decade.

If the user paired the 9900X3D with a different GPU, the frame rates would rise, but that is outside this dataset. The current combination is fundamentally GPU-bound.

How This Combo Ranks

The combo rank in the database is 3437 out of 3723 tested combinations. That places it in the bottom 8% of all CPU-GPU pairings in the database. The percentileVsAllCpus for the CPU is 91, meaning it is faster than 91% of all CPUs, but the GPU is in the 5th percentile. The combination of a top-tier CPU and a bottom-tier GPU results in a very low overall rank because the GPU dominates the gaming performance. In Rust, the specific combination rank is 3437 out of 3723, which is lower than 92.3% of the tested combos.

This rank is not surprising given the frame rates. Only one setting across 12 possible configurations reaches 60 FPS. The majority of the configurations average below 50 FPS, and the 4K presets all average below 30 FPS. The database ranks this as a poor gaming combo, not because the CPU is weak, but because the GPU is severely underpowered for any modern title. The 9900X3D is overkill for the Arc B370, and the combination wastes the CPU's potential.

The Verdict

No, this PC cannot run Rust at 60 FPS at most settings and resolutions. The verdict by resolution is as follows:

• At 3840x2160: no playable settings. The best average FPS is 31 at Low, which is 29 FPS below the threshold. The system is not playable at any preset.
• At 2560x1440: no playable settings. The best average FPS is 49 at Low. It is 11 FPS short. No other preset comes close.
• At 1920x1080: only the Low preset is playable, with an average of 69 FPS. Medium, High, and Ultra all fall below 60 FPS, with Medium at 46, High at 39, and Ultra at 30.

The verdict field confirms this: 3840x2160 has no playable settings, 2560x1440 has no playable settings, and 1920x1080 has only Low. The most demanding preset that stays at or above 60 FPS is Low at 1080p. If the user wants to play at 1080p with Medium or higher, they will need a discrete GPU, not this integrated solution.

The data is measured, not estimated, and the pattern is unmistakable. The 9900X3D is more than capable, but the Arc B370 is a bottleneck that limits Rust to 1080p Low. The 4K and Ultra settings are effectively unplayable, and even 1440p Low is not worth attempting due to the 49 FPS average.
