Rust

The AMD Ryzen 9 5950X paired with the Intel Arc B390 presents a highly unusual combination for running Rust, a survival game known for its demanding simulation and rendering loads. The recorded data shows a system where the CPU is a top-tier 16-core, 32-thread processor, while the GPU is an integrated solution with a benchmark percentile ranking that places it far below most dedicated graphics cards. This analysis walks through the measured frame rates, component roles, and performance comparisons to determine what this system can realistically deliver.

Best Settings per Resolution

The database records a playable threshold of 60 FPS for Rust. Using that standard, the only settings configuration that clears this bar is at 1920x1080 with Low settings. The data shows an average of 76 FPS at this resolution and preset, which is the single playable combination for this entire hardware pairing.

At 1920x1080, the Medium preset produces an average of 51 FPS, which falls below the 60 FPS target. High settings at this resolution yield 43 FPS, and Ultra drops to 33 FPS. None of these meet the playable threshold. The Low preset is the only option that stays above 60 FPS, and it does so with a notable margin of 16 FPS over the threshold.

Moving to 2560x1440, no preset achieves 60 FPS. The Low settings average 53 FPS, which is the closest result at this resolution, but it still misses the target by 7 FPS. Medium settings average 35 FPS, High averages 30 FPS, and Ultra averages 23 FPS. The verdict data confirms that 2560x1440 has no playable settings for this system.

At 3840x2160, the situation is more difficult. Low settings average 31 FPS, Medium averages 21 FPS, High averages 18 FPS, and Ultra averages 13 FPS. The verdict data lists no playable settings for 4K. The best that can be said is that Low settings at 4K are still running at half the 60 FPS target.

For users seeking the most demanding preset that stays at or above 60 FPS, the answer is exclusively 1920x1080 with Low settings, delivering 76 FPS average. This is the only data point in the entire measured set that meets the playable threshold. The database shows that every other preset, at every other resolution, falls short.

CPU and GPU Roles

The data reveals a stark imbalance between the CPU and GPU in this pairing. The Ryzen 9 5950X is a high-end desktop processor with a percentile ranking of 91 among all CPUs, and a 3DMark max-threads score of 11597. Its Cinebench R23 multicore score of 26017 reflects substantial processing power. The Intel Arc B390, however, has a percentile ranking of 9 among all GPUs, with a single 3DMark Steel Nomad DX12 score of 1482. This places it in the same performance tier as very old or entry-level mobile graphics chips.

The measured FPS scaling across resolutions points to the GPU as the primary bottleneck. Consider the 1920x1080 Low settings average of 76 FPS. When moving to 2560x1440 Low, the average drops to 53 FPS, a reduction of 30%. Moving from 1440p Low to 4K Low, the average falls from 53 to 31 FPS, another 41% reduction. This pattern of large FPS losses as resolution increases is characteristic of a GPU-bound scenario. The CPU is not changing; only the rendering load on the GPU is growing.

The settings scaling reinforces this. At 1920x1080, Low to Medium high yields a drop from 76 to 51 FPS, a 33% decrease. Low to High drops to 43 FPS, a 43% decrease. Low to Ultra drops to 33 FPS, a 57% decrease. These large margins show that the GPU cannot handle the additional shading and texture work. A CPU-bound scenario would show frame rates that are much flatter across settings, since the CPU would be the limiting factor regardless of graphical detail.

The 3DMark scores of the CPU further support this. The 3DMark 16-thread score of 10810 and max-threads score of 11597 are strong for a desktop CPU. However, the GPU's single benchmark score of 1482 is extremely low. The database shows that the Arc B390's nearest rivals are the NVIDIA GeForce GT 520MX with an average score of 1463 and the GeForce GT 710 with a score of 1443. These are not modern gaming GPUs. The data clearly shows that, at all three tested resolutions, the Intel Arc B390 is the component that determines the frame rate ceiling.

The system is not using a CPU bottleneck at any point. Even at 4K Low, where the CPU has to work harder to feed frames, the GPU is still the limiting factor. The CPU's high single-thread performance, evidenced by a Passmark single-thread score of 3470 and a Cinebench R23 single-core of 1614, is sufficient to avoid limiting the GPU at these low frame rates. The conclusion from the recorded data is that the GPU dictates all performance outcomes, from 1080p to 4K.

Measured FPS Breakdown

The database provides a complete set of measured FPS data across three resolutions and four settings. Each data point is a direct measurement of this specific CPU and GPU combination.

At 3840x2160, the results are consistently below playable levels. The Low preset averages 31 FPS. Medium averages 21 FPS, with a minimum of 18 and a maximum of 24. High averages 18 FPS. Ultra averages 13 FPS. The 4K data shows no minimum or maximum values for three of the four presets, but the Medium preset gives a clear range of 18 to 24 FPS, indicating a very tight and low range.

For 2560x1440, the averages are higher but still do not reach the 60 FPS target. Low settings produce 53 FPS average. Medium produces 35 FPS, with a recorded range of 30 to 41 FPS. High settings yield 30 FPS average. Ultra drops to 23 FPS average. The Medium preset at 1440p shows a 12 FPS difference between min and max, which is a wider frame time spread than the 4K Medium preset.

The most complete dataset is at 1920x1080. Low settings average 76 FPS, which is the highest recorded average in the entire dataset. Medium settings average 51 FPS, with a minimum of 44 and a maximum of 59. High settings average 43 FPS. Ultra settings average 33 FPS. The Medium preset at 1080p is particularly interesting as it is the only recorded preset that approaches the 60 FPS threshold, peaking at 59 FPS maximum, but still averaging 9 FPS below the target.

A pattern emerges when comparing similar settings across resolutions. For Low settings, the FPS goes from 76 at 1080p to 53 at 1440p to 32 at 4K. For Medium, it goes from 51 at 1080p to 35 at 1440p to 21 at 4K. For High, it goes from 43 at 1080p to 30 at 1440p to 18 at 4K. For Ultra, it goes from 33 at 1080p to 23 at 1440p to 13 at 4K. The consistent halving of frame rates from 1080p to 4K for each preset is a clear sign of a uniform GPU bottleneck.

Similar Performance Alternatives

Looking at the nearest rivals for both components provides useful context for what this system is comparable to. The CPU, the Ryzen 9 5950X, has an average benchmark score of 51947. Its nearest rivals in the database are all within a small margin. The Intel Core Ultra 5 235HX has an average score of 52073, which is 0.2% lower than the 5950X. The AMD EPYC 8124P scores 52121, 0.3% lower. The Intel Core i9-13900F scores 51730, which is 0.4% higher. The Intel Core i7-14700 scores 52301, which is 0.7% lower. These results show that the CPU is comparable to a wide range of high-end desktop and workstation chips, all within a 0.7% performance band. Any of these would likely provide the same CPU performance in Rust, which is good since the CPU is not the limiting factor.

The GPU tells a different story. The Intel Arc B390 has an average benchmark score of 1482. Its nearest rivals are all much older or low-end GPUs. The NVIDIA GeForce GT 520MX has an average score of 1463, which is 1.3% lower. The NVIDIA GeForce GT 800M has 1460, 1.5% lower. The GeForce GT 625 OEM has 1446, 2.5% lower. The GeForce GT 710 has 1443, 2.7% lower. This means the Arc B390 performs within a 3% margin of these very old graphics chips. In practice, any of these GPUs would produce similar frame rates in Rust. The database shows that the GPU is the primary determinant of the measured FPS values. If a user had any of these rival GPUs instead of the Arc B390, the game performance would be nearly identical.

The Verdict

The recorded data provides a clear verdict. This PC can run Rust, but only under a narrow set of conditions. According to the verdict by resolution, at 3840x2160 there are no playable settings. The best possible scenario is Low at 31 FPS, which is unplayable by the 60 FPS standard. At 2560x1440, there are also no playable settings. The best is Low at 53 FPS, which is 7 FPS short of the target. At 1920x1080, the system can run the game. The playable settings list includes only Low, and the best settings for 1080p is Low with an average FPS of 76. This is 16 FPS above the 60 FPS threshold.

The verdict is that this system is playable only at 1920x1080 with Low settings. Any attempt to increase the resolution or the graphics preset will cause the frame rate to drop below 60 FPS. The data shows that the system is heavily GPU-bound, and the Arc B390 does not have the rendering power to handle Rust at higher settings. The CPU is more than capable, but it is held back by the GPU. The system will be able to play Rust at 1080p Low, but users should not expect smooth performance at higher settings.

How This Combo Ranks

The database ranks this specific combination of AMD Ryzen 9 5950X and Intel Arc B390. The combo rank in Rust is 3312 out of 3723 total tested combinations. This places it in the lower 11th percentile of all tested combos for this game.

The rank is a direct reflection of the GPU's performance. The CPU is a high-performing part, but the database's ranking for the GPU is low. The Arc B390 has a percentile ranking of 9 among all GPUs, meaning it performs better than only 9% of the GPUs in the database. This low GPU ranking pulls the entire system down in the rankings.

The nearest rival comparisons for the GPU show it is in the same performance class as the GeForce GT 520MX and GT 710. Those are not parts that are associated with modern gaming. As a result, the combo ranking of 3312 is expected. The CPU is capable of running any game, but the GPU cannot deliver the frame rate output that a competitive system would need. The system is only able to play Rust at 1080p Low, and even that is only a 76 FPS average. This places it well below the average system in the database. For a user looking to play Rust smoothly at higher settings, this combination is not a suitable one. The recorded data shows that the system can handle the game at the most basic level, but it is ranked to be in the bottom 11% of all other combos.
