Rust

Measured FPS Breakdown

The recorded data for this AMD Ryzen 7 9800X3D and Intel Arc B390 combination shows a clear performance ceiling imposed by the graphics solution. At 4K, the frame rates are consistently low. At 3840x2160 with High settings, the average FPS is 18. Dropping to Medium yields an average of 21 FPS, with a recorded range of 18 to 24 FPS. The Low preset at this resolution produces an average of 31 FPS, while the Ultra preset falls to an average of 13 FPS. None of these figures approach the 60 FPS threshold considered playable in the database.

At 2560x1440, the situation improves but remains below the playability bar. The High preset averages 30 FPS. Medium produces an average of 35 FPS, with a range of 30 to 41 FPS. The Low preset reaches an average of 53 FPS, coming closer to the target. The Ultra preset, however, drops to an average of 23 FPS. Even the best result at this resolution, the Low preset at 53 FPS, falls short of the 60 FPS benchmark.

At 1920x1080, the data shows a more viable picture. The Low preset achieves an average of 76 FPS, which clears the playable threshold. The Medium preset yields an average of 51 FPS, with a range of 44 to 59 FPS, narrowly missing the target. High settings average 43 FPS, while Ultra averages 33 FPS. The data indicates that only the Low preset at 1080p reaches a consistently playable frame rate.

Best Settings per Resolution

For 3840x2160, no settings preset achieves the 60 FPS target. The database records no playable settings at this resolution. The highest average recorded was 21 FPS on the Low preset, which is insufficient for smooth gameplay.

At 2560x1440, the result is the same: no playable settings. The best attempt, again the Low preset, averages 53 FPS. This is a significant improvement over 4K but still not enough to meet the playability standard.

At 1920x1080, the Low preset is the only configuration that clears the 60 FPS threshold. It averages 76 FPS. This is the single playable configuration in the entire measurement set. The Medium preset averages 51 FPS, which is below the threshold, so it is not recommended for a consistent 60 FPS experience.

FAQ

Q: What is the highest FPS recorded in any configuration?

A: The highest average FPS recorded is 76 FPS, achieved at 1920x1080 with the Low preset. This is the only configuration in the entire dataset that clears the 60 FPS threshold.

The Verdict

The recorded data answers the question directly: this combo can run Rust, but only under the most restrictive conditions. The verdict by resolution is clear. At 3840x2160, there are no playable settings; the 13 to 21 FPS range across presets makes the game effectively unplayable at this resolution. At 2560x1440, the situation is similar, with no preset reaching the 60 FPS mark. The best result here is the Low preset at 53 FPS.

At 1920x1080, the system finally delivers a playable experience. The Low preset achieves an average of 76 FPS, which is above the 60 FPS threshold. This is the only playable configuration in the dataset. The Medium preset at 1080p averages 51 FPS, which is not playable according to the threshold.

The verdict is that this PC can run Rust at 1920x1080 with Low settings, providing a playable experience. For any higher resolution or higher quality preset, the performance falls below the playable threshold. Users expecting to run Rust at higher visual fidelity or higher resolutions will need to consider the limitations of this combination.

CPU and GPU Roles

The data reveals a stark imbalance between the CPU and GPU capabilities. The AMD Ryzen 7 9800X3D is a high-end processor with a strong benchmark profile, including a Cinebench R23 multicore score of 23230 and a Geekbench single-core score of 2964. In contrast, the Intel Arc B390, as an iGPU, shows significantly lower performance, with a 3DMark Steel Nomad score of 1482. This score places it in the 9th percentile of all GPUs, indicating a weak graphics solution.

When comparing the scaling between resolutions, the influence becomes evident. The FPS drops sharply as resolution increases. At Low settings, the average FPS goes from 76 at 1920x1080 to 53 at 2560x1440, and then to 21 at 3840x2160. This is a reduction of roughly one-third from 1080p to 1440p, and then more than half from 1440p to 4K. This scaling pattern is classic for a GPU-bound scenario, where the graphics processor is the limiting factor.

The CPU, with its high core and thread count, is likely not the bottleneck in this configuration. The data shows that the frame rates are heavily constrained by the GPU, especially at higher resolutions. The 3DMark score of 1482, which is comparable to the GeForce GT 520MX and GT 710, confirms the low level of graphics performance. The CPU's capabilities are largely unused, as the GPU cannot process frames fast enough to utilize the processor's potential.

At 1920x1080 with the Low preset, the GPU is still the primary constraint, but the CPU has enough headroom to support the 76 FPS result. At higher resolutions, the GPU is fully saturated, and the CPU's role becomes secondary. The benchmark results indicate that the GPU is the dominant component in Rust performance, with the CPU having little to no impact on the frame rate differences across resolutions and presets.

The scaling between the Medium and Ultra presets also confirms the GPU limitation. At 1920x1080, the average FPS drops from 51 on Medium to 33 on Ultra, a reduction of 35%. At 2560x1440, it drops from 35 to 23, also a 34% reduction. At 4K, the drop is from 21 to 13, a 39% reduction. This consistent pattern across resolutions indicates that the GPU is the primary limiter, and the CPU is not a significant factor in this game.

How This Combo Ranks

The combination of the AMD Ryzen 7 9800X3D and the Intel Arc B390 is ranked 3312 out of 3723 tested combos in Rust. This places it in the bottom 11% of all measured systems. The rank is heavily influenced by the GPU, which sits in the 9th percentile of all GPUs. The CPU, in contrast, is in the 87th percentile of all CPUs.

The CPU's nearest rivals in the database include the AMD Ryzen 7 PRO 8840HS, which has an average score of 39603, a 0.4% difference from the 9800X3D. The AMD Ryzen AI 9 365 is 0.7% lower, the AMD Ryzen AI 7 450 is 0.7% higher, and the AMD Ryzen 7 7700 is 0.8% higher. These small deltas show that the 9800X3D is competitive with other high-end processors, but this does not translate into game performance due to the GPU bottleneck.

The GPU's nearest rivals are all much weaker. The GeForce GT 520MX scores 1463, a 1.3% difference. The GeForce 800M is 1.5% higher, the GT 625 OEM is 2.5% higher, and the GT 710 is 2.7% higher. These are all entry-level graphics solutions from previous generations. The Arc B390's score of 1482 is only marginally better than these, confirming its limited capacity.

The combination rank of 3312 out of 3723 is a direct result of this mismatch. A high-end CPU paired with an entry-level GPU creates an unbalanced system that performs poorly in GPU-heavy games like Rust. The data shows that this combo is only suitable for 1080p gaming on the lowest settings. For any other use case, the system will not meet the playable threshold. The ranking reflects this, placing the combination in the bottom 8% of all tested systems.
