Rust

Measured FPS Breakdown

The benchmark results for the AMD Ryzen 9 9900X and Intel Arc B390 combination in Rust are heavily dependent on both resolution and preset selection. The data is measured, not estimated, and the playable threshold is set at 60 frames per second. At 4K (3840x2160), the combination struggles significantly. At High settings, the average FPS is 18. Low settings raise that to 31 average. Medium settings produce an average of 21 FPS, with a minimum of 18 and a maximum of 24. Ultra settings drop the average to 13 FPS. No preset at this resolution reaches the 60 FPS threshold, and the recorded data shows a clear ceiling below 35 FPS.

Moving to 1440p (2560x1440), the results improve but remain far from playable. High settings yield an average of 30 FPS. Low settings jump to 53 FPS average. Medium settings average 35 FPS, with a minimum of 30 and a maximum of 41. Ultra settings average 23 FPS. Again, no preset clears the 60 FPS mark, and even the best case, Low, falls 7 FPS short of the playable threshold.

At 1080p (1920x1080), the combination finally shows a playable configuration. Low settings deliver an average of 76 FPS, which exceeds the 60 FPS threshold by a comfortable margin. High settings average 43 FPS, Medium averages 51 FPS with a minimum of 44 and a maximum of 59, and Ultra averages 33 FPS. The data indicates that only the Low preset at 1080p is viable, while all other settings at this resolution miss the 60 FPS target. The Medium preset at 1080p comes closest among the non-playable options, with an average of 51 FPS, but its maximum of 59 FPS still falls below the threshold.

FAQ

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

A: No. The verdict data for 3840x2160 lists no playable settings. The best average FPS at 4K is 31 on Low settings, which is far below the 60 FPS playable threshold. High, Medium, and Ultra average 18, 21, and 13 FPS respectively.

Q: What is the best playable configuration for this system?

A: The only playable settings are at 1920x1080 with the Low preset, which achieves an average of 76 FPS. This is the sole configuration across all resolutions and presets that clears the 60 FPS threshold. The verdict data confirms 1080p Low as the best settings, with an average FPS of 76.

Q: How does the Intel Arc B390 compare to its nearest rivals?

A: The Arc B390 has an average benchmark score of 1482. Its nearest rival, the NVIDIA GeForce GT 520MX, scores 1463, which is 1.3% lower. The GeForce 800M scores 1460 (1.5% lower), the GeForce GT 625 OEM scores 1446 (2.5% lower), and the GeForce GT 710 scores 1443 (2.7% lower). This places the Arc B390 slightly ahead of these older GPUs, but the percentile ranking of 9 indicates very low overall performance relative to all GPUs.

Q: What is the performance gap between Low and Ultra settings at 1440p?

A: At 2560x1440, the Low preset averages 53 FPS, while Ultra averages 23 FPS. This represents a 30 FPS difference, meaning Low settings deliver roughly 2.3 times the average frame rate of Ultra. Medium sits between at 35 FPS average, and High at 30 FPS.

Q: Does the CPU or GPU limit performance more in this game?

A: The data suggests the GPU is the primary bottleneck. The AMD Ryzen 9 9900X ranks in the 92nd percentile among all CPUs, with a strong multi-core score of 32172 in Cinebench R23. In contrast, the Intel Arc B390 ranks in the 9th percentile among all GPUs. The measured FPS scales directly with resolution changes, which is typical for GPU-bound scenarios, indicating the Arc B390 is the limiting factor.

Q: What are the minimum and maximum FPS values recorded for Medium settings?

A: The recorded data includes min/max values only for Medium settings. At 3840x2160, the minimum is 18 FPS and the maximum is 24 FPS. At 2560x1440, the minimum is 30 FPS and the maximum is 41 FPS. At 1920x1080, the minimum is 44 FPS and the maximum is 59 FPS. No min/max values are provided for Low, High, or Ultra presets.

Similar Performance Alternatives

Looking at the nearest rivals for both components, this system behaves similarly to configurations built around the CPU and GPU alternatives listed in the database. For the AMD Ryzen 9 9900X, the closest matches by average benchmark score are the AMD EPYC 9015, which scores 57555 and is 0.1% lower, and the AMD EPYC 7313, which scores 57399 and is 0.2% higher. The Intel Core i9-14900 scores 58115, which is 1.1% higher, and the Intel Xeon Platinum 8260M scores 58323, which is 1.4% higher. Any of these CPUs paired with the same Intel Arc B390 would likely produce very similar FPS results in Rust, as the CPU performance delta is minimal and the GPU remains the dominant constraint.

For the Intel Arc B390, the nearest GPU rivals are all NVIDIA models from older generations. The GeForce GT 520MX is 1.3% slower, the GeForce 800M is 1.5% slower, the GeForce GT 625 OEM is 2.5% slower, and the GeForce GT 710 is 2.7% slower. Swapping the Arc B390 for any of these GPUs would yield nearly identical performance, meaning the same 1080p Low playable configuration and the same sub-60 FPS results at higher resolutions. Conversely, a system with the AMD Ryzen 9 9900X and any of these rival GPUs would behave almost exactly like the tested combination, since the CPU's high multi-threaded scores (e.g., 32172 in Cinebench R23) are not the limiting factor in Rust at these settings.

The data indicates that the GPU's percentile ranking of 9 places it among the lowest-performing cards in the database, and its nearest rivals are all similarly limited. For users seeking better frame rates, the upgrade path would involve a substantially faster GPU, as the CPU has ample headroom, evidenced by its 92nd percentile ranking and multi-core score of 54643 in Passmark multithread tests.

The Verdict

Can this PC run Rust? Based on the verdict by resolution, the answer depends entirely on the target resolution and preset. At 3840x2160, there are no playable settings, meaning no configuration reaches the 60 FPS threshold. The highest average FPS at 4K is 31 on Low, which is unplayable by the database's standard. Similarly, at 2560x1440, there are no playable settings, with the best case being Low at 53 FPS average, still 7 FPS short of the 60 FPS target.

At 1920x1080, the system clears the threshold, but only on Low settings. The Low preset delivers an average of 76 FPS, which exceeds the 60 FPS playable threshold by 16 FPS. The verdict data confirms that 1080p Low is the best settings, with an average FPS of 76. All other presets at 1080p fail: High averages 43 FPS, Medium averages 51 FPS, and Ultra averages 33 FPS. The Medium preset's maximum of 59 FPS is still below the playable threshold, so even with frame time variations, it does not qualify.

In summary, this combination can run Rust only at 1080p with the Low preset. For 1440p or 4K gaming, the hardware is insufficient, and even at 1080p, higher quality settings are not viable. Users should expect to prioritize frame rate over visual fidelity with this setup.

CPU and GPU Roles

The division of labor between the AMD Ryzen 9 9900X and the Intel Arc B390 is clear from the scaling data. The CPU is a high-end part, ranking in the 92nd percentile among all CPUs, with strong synthetic scores such as 32172 in Cinebench R23 multi-core and 54643 in Passmark multithread. The GPU, by contrast, ranks in the 9th percentile among all GPUs, with a single 3DMark Steel Nomad DX12 score of 1482. This massive disparity indicates that the GPU is the bottleneck in Rust.

The resolution scaling confirms this. At 1080p Low, the average FPS is 76. At 1440p Low, it drops to 53, a 30% reduction. At 4K Low, it drops to 31, a further 42% reduction. This pattern is characteristic of GPU-bound performance, where increasing pixel count directly taxes the renderer. If the CPU were the limiter, the FPS would remain relatively flat across resolutions, as the CPU workload in Rust would not scale as severely with resolution.

Preset scaling also points to the GPU. At 1080p, moving from Low to High reduces the average FPS from 76 to 43, a 43% drop. At 1440p, the same move reduces FPS from 53 to 30, a 43% drop. At 4K, Low to High reduces FPS from 31 to 18, a 42% drop. The consistent proportional decline across resolutions indicates that the GPU's shading and pixel throughput are the limiting factors, not the CPU's ability to feed the renderer.

The CPU's role is to maintain frame pacing and handle game logic, and its high multi-threaded score of 13929 in 3DMark max threads suggests it is more than capable. However, the GPU's low pixel rate of 60.00 GPixel/s and texture rate of 120.0 GTexel/s, combined with its shared memory architecture, cannot keep up with the demands of Rust at higher resolutions or presets. The conclusion is that the GPU is the dominant factor, and upgrading it would yield far larger FPS gains than any CPU change.

How This Combo Ranks

In the database of tested combinations, this pairing of AMD Ryzen 9 9900X and Intel Arc B390 ranks 3312 out of 3723 total combos. This places it in the bottom 11% of all tested systems, which is consistent with the GPU's low percentile ranking. The rank is driven almost entirely by the GPU, as the CPU alone would rank much higher based on its 92nd percentile standing.

The rank of 3312 means that the vast majority of tested combinations deliver better performance in Rust. The measured FPS data supports this: only one configuration (1080p Low) achieves playable frame rates, and even that is at the lowest visual quality preset. For perspective, the combo rank is not a reflection of the CPU's capability, but rather the severe imbalance between the high-end processor and the entry-level integrated graphics solution.

Users considering this combination should understand that the Arc B390's performance class, as indicated by its nearest rivals (all NVIDIA GT-series or 800M-series GPUs), is far below what is needed for modern gaming at high settings. The combo rank of 3312 out of 3723 is a clear warning that this system is not suited for Rust beyond minimal settings at 1080p. The database records show no other resolution or preset that meets the 60 FPS playable threshold, making this one of the least capable combinations for this game among those tested.
