Rust

Measured FPS Breakdown

The recorded data for Rust with the AMD Ryzen 9 9950X3D and Intel Arc B390 shows a clear pattern: frame rates scale predictably with resolution and preset, but the GPU becomes the limiting factor almost immediately. At 4K, the combo cannot deliver playable performance under any setting. The High preset averages 18 FPS, Low averages 31 FPS, Medium averages 21 FPS with a minimum of 18 FPS and maximum of 24 FPS, and Ultra drops to 13 FPS. None of these approach the 60 FPS playability threshold.

Stepping down to 2560x1440 improves matters, but not enough. High averages 30 FPS, Low reaches 53 FPS, Medium averages 35 FPS with a range of 30 to 41 FPS, and Ultra sits at 23 FPS. The best result here, Low at 53 FPS, is still 7 FPS short of the playable mark. The gap between Low and Medium at this resolution is 18 FPS, indicating that even modest graphical increases heavily tax the Arc B390.

At 1920x1080, the picture changes. Low settings produce an average of 76 FPS, which clears the 60 FPS threshold with 16 FPS to spare. Medium averages 51 FPS with a minimum of 44 FPS and maximum of 59 FPS, High averages 43 FPS, and Ultra averages 33 FPS. The jump from Low to Medium costs 25 FPS, and from Medium to High costs another 8 FPS. This suggests that the Arc B390 has a narrow operating window: it can handle Rust at 1080p Low, but any higher preset pushes it below playable levels.

The min/max data for Medium presets is revealing. At 1080p Medium, the 44 FPS minimum means even the worst-case frame dips stay above 40 FPS, but the 59 FPS maximum never reaches 60. At 1440p Medium, the 30 FPS minimum and 41 FPS maximum show a tighter, lower band. At 4K Medium, the 18 to 24 FPS range confirms severe GPU-bound performance. Across all resolutions, Ultra settings are the worst performers, and Low settings are the only ones that ever hit 60 FPS or above, doing so exclusively at 1080p.

FAQ

Q: Can this PC run Rust at 4K with playable frame rates?

A: No. The recorded data shows no playable settings at 3840x2160. The best average FPS at this resolution is 31 FPS on Low, which is far below the 60 FPS playability threshold. Ultra averages just 13 FPS.

Q: What is the highest preset that stays at or above 60 FPS at 1080p?

A: Low is the only setting at 1920x1080 that clears 60 FPS, with an average of 76 FPS. Medium averages 51 FPS, High averages 43 FPS, and Ultra averages 33 FPS, all below the threshold.

Q: How does the Arc B390 compare to its nearest GPU rivals in this configuration?

A: The Arc B390's average benchmark score is 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). The Arc B390 leads this group by a narrow margin.

Q: What is the best frame rate this combo achieves in Rust?

A: The highest recorded average FPS is 76, achieved at 1920x1080 with Low settings. The next best is 53 FPS at 2560x1440 with Low settings, followed by 51 FPS at 1920x1080 with Medium settings.

Q: How does the Ryzen 9 9950X3D compare to its nearest CPU rivals?

A: The Ryzen 9 9950X3D has an average benchmark score of 75779. The AMD Ryzen 7 PRO 9755 scores 75738 (0.1% lower), the Ryzen 7 PRO 9755X3D scores 75716 (0.1% lower), the AMD EPYC 8224P scores 75582 (0.3% lower), and the Intel Core Ultra 9 285 scores 75488 (0.4% lower). The Ryzen 9 leads all of them, but by less than half a percent.

Q: Is the CPU or GPU the bottleneck in this system for Rust?

A: The data strongly implicates the GPU. The Ryzen 9 9950X3D ranks in the 95th percentile among all CPUs, with a Cinebench R23 multicore score of 42018 and a single-core score of 2259. The Arc B390, by contrast, sits in the 9th percentile among all GPUs. The measured FPS drops sharply with resolution and preset, which is characteristic of GPU-bound performance.

Best Settings per Resolution

At 3840x2160, no preset reaches 60 FPS. The best recorded average is 31 FPS on Low, but that is still 29 FPS short of the playable threshold. Medium averages 21 FPS, High averages 18 FPS, and Ultra averages 13 FPS. There is no recommended setting for 4K in terms of playability.

At 2560x1440, the situation is similar. No preset clears 60 FPS. Low comes closest with 53 FPS, but the 7 FPS shortfall means the game is not playable at this resolution. Medium averages 35 FPS, High averages 30 FPS, and Ultra averages 23 FPS. The best option, Low, is still below the threshold.

At 1920x1080, Low is the only playable preset, with an average of 76 FPS. This is the single setting across all resolutions that meets the 60 FPS requirement. Medium falls to 51 FPS, High to 43 FPS, and Ultra to 33 FPS. For users who prioritize smoothness over visuals, 1080p Low is the only viable configuration. The gap between Low and Medium is 25 FPS, so stepping up to Medium sacrifices a substantial portion of the frame rate headroom.

Similar Performance Alternatives

On the CPU side, the AMD Ryzen 9 9950X3D is closely matched by several processors in the database. The AMD Ryzen 7 PRO 9755 has an average score of 75738, just 0.1% lower. The AMD Ryzen 7 PRO 9755X3D scores 75716, also 0.1% lower. The AMD EPYC 8224P trails by 0.3% with a score of 75582, and the Intel Core Ultra 9 285 is 0.4% behind at 75488. In practical terms, any of these CPUs would deliver nearly identical performance in Rust, since the game is heavily GPU-bound with this particular graphics card. The Ryzen 9's 16 cores and 32 threads, along with its 128 MB of L3 cache, are more than sufficient for the workload, but the GPU prevents those resources from being fully utilized.

On the GPU side, the Intel Arc B390's nearest rivals are all older NVIDIA parts. The GeForce GT 520MX scores 1463 (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). These deltas are small, meaning a system with any of these GPUs would produce similar FPS numbers in Rust. However, all of them, including the Arc B390, are far below the performance level needed for smooth gameplay at higher presets. The Arc B390's 1536 shading units, 48 TMUs, and 24 ROPs, paired with 12 ray tracing cores, are simply not enough for Rust's demands beyond 1080p Low.

How This Combo Ranks

The combination of the AMD Ryzen 9 9950X3D and Intel Arc B390 ranks 3312 out of 3723 tested combos in Rust. This places it in the bottom 11% of the database, a direct reflection of the GPU's limitations. The CPU is a top-tier part, ranking in the 95th percentile among all processors, but the GPU sits in the 9th percentile. The pairing creates a massive imbalance: the Ryzen 9 is capable of far more, but the Arc B390 holds the system back.

The ranking is consistent with the measured FPS data. At 1080p Low, the system achieves 76 FPS, which is playable, but the margin is thin. At every other resolution and preset, the combo falls below 60 FPS. The rank of 3312 out of 3723 suggests that most other tested combinations deliver better performance in Rust, even those with weaker CPUs paired with stronger GPUs. The data indicates that swapping the Arc B390 for a more capable graphics card would dramatically improve the ranking, while swapping the CPU would have little effect given the GPU bottleneck.

The Verdict

Can this PC run Rust? The answer depends entirely on the resolution and settings. At 1920x1080 with Low settings, yes: the recorded average of 76 FPS clears the 60 FPS playability threshold, and this is the only configuration in the database that does so. At the same resolution with Medium settings, the average drops to 51 FPS, which is not playable by the 60 FPS standard. High and Ultra are worse still, at 43 FPS and 33 FPS respectively.

At 2560x1440, the verdict is no. The best recorded average is 53 FPS on Low, 7 FPS short of the threshold. Medium averages 35 FPS, High averages 30 FPS, and Ultra averages 23 FPS. At 3840x2160, the verdict is also no. Low averages 31 FPS, Medium averages 21 FPS, High averages 18 FPS, and Ultra averages 13 FPS. The database lists no playable settings for either 1440p or 4K.

The core issue is the Intel Arc B390. With a 7.680 TFLOPS FP32 throughput and a 60.00 GPixel/s pixel rate, it is designed for basic graphical tasks, not demanding survival games. The Ryzen 9 9950X3D, with its 16 cores, 32 threads, and 5.70 GHz boost clock, is not the limiting factor. Users who want to play Rust at higher presets or resolutions would need a significantly more powerful GPU. For those willing to accept 1080p Low, the system is functional, but just barely. The 76 FPS average provides some headroom, but the 44 FPS minimum at 1080p Medium suggests that frame dips could be noticeable in busy scenes even at Low settings.
