Rust

Can AMD Ryzen 7 5700 + Intel Arc B390 run Rust? The short answer is: only at 1080p with the Low preset does this combination clear the 60 FPS playable threshold. The benchmark data shows a system that is heavily constrained by the graphics processor, with the CPU having plenty of headroom left on the table.

Measured FPS Breakdown

The recorded measurements for this combination in Rust show a clear pattern: as resolution increases, average frame rates drop sharply, and the gap between Low and Ultra presets widens dramatically. At 1920x1080, the Low preset delivers an average of 76 FPS, which is the only configuration across all resolutions that exceeds the 60 FPS playable threshold. The Medium preset at this resolution averages 51 FPS, with recorded minimums of 44 FPS and maximums of 59 FPS, placing it just below the playable mark. High settings at 1080p drop further to 43 FPS average, while Ultra falls to 33 FPS average.

Moving up to 2560x1440, performance takes a significant hit across all presets. Low settings average 53 FPS, which is close to but still under the 60 FPS target. Medium averages 35 FPS (minimum 30, maximum 41), High averages 30 FPS, and Ultra averages 23 FPS. None of these configurations achieve playable status.

At 3840x2160, the results are more demanding. Low settings average 31 FPS, Medium averages 21 FPS (minimum 18, maximum 24), High averages 18 FPS, and Ultra averages just 13 FPS. The data shows a steep scaling curve: dropping from 1080p Low to 4K Low costs 45 FPS on average, while the difference between Low and Ultra at 4K is 18 FPS.

The min and max values recorded for Medium presets suggest frame pacing is consistent, with the 1080p Medium spread of 44 to 59 FPS showing a tight band. The 1440p Medium spread of 30 to 41 FPS and 4K Medium spread of 18 to 24 FPS follow similar patterns. No min or max values were recorded for the other presets, so the data focuses on averages for those configurations.

Similar Performance Alternatives

The database places the Intel Arc B390 in a very specific performance tier, with its nearest rivals all being older, low-end NVIDIA parts. The Arc B390 scores 1482 in the 3DMark Steel Nomad DX12 test, which is 1.3% ahead of the GeForce GT 520MX (1463 score), 1.5% ahead of the GeForce 800M (1460), 2.5% ahead of the GeForce GT 625 OEM (1446), and 2.7% ahead of the GeForce GT 710 (1443). This places the Arc B390 at the 9th percentile of all GPUs, meaning it outperforms only about 9% of the database's tested graphics cards.

On the CPU side, the AMD Ryzen 7 5700 sits at the 78th percentile of all CPUs, with an average benchmark score of 25517. Its nearest rivals are extremely close in performance: the Intel Xeon D-2752TER scores 25530 (0.1% faster), the AMD Ryzen 5 7640U scores 25485 (0.1% slower), the AMD Ryzen 5 6600H scores 25550 (0.1% faster), and the AMD Ryzen 7 5825U scores 25446 (0.3% slower). These deltas are within noise, meaning any of these CPUs would deliver virtually identical frame rates when paired with the same GPU.

For practical purposes, a builder looking at this combo should expect the GPU to be the limiting factor. Swapping the Ryzen 7 5700 for any of its nearest rivals would change performance by less than 0.3%, while swapping the Arc B390 for a GT 710 would drop the GPU score by 2.7%, which would likely push 1080p Low below the 60 FPS mark.

CPU and GPU Roles

The recorded data makes it clear that the Intel Arc B390 is the dominant bottleneck in this pairing. The CPU is a strong 8-core, 16-thread part with a 78th percentile ranking, while the GPU sits at the 9th percentile. In Rust, which is known for CPU-heavy simulation, this imbalance shows up in the scaling between resolutions.

At 1920x1080 Low, the system achieves 76 FPS. Dropping to 2560x1440 Low reduces this to 53 FPS, a 30% decrease. Going further to 3840x2160 Low yields 31 FPS, another 41% drop. This steep decline with resolution indicates the GPU is saturated well before the CPU runs out of headroom. If the CPU were the limiting factor, resolution changes would have a much smaller impact on frame rates.

The preset scaling tells a similar story. At 1080p, moving from Low to Medium costs 25 FPS (76 to 51), from Medium to High costs 8 FPS (51 to 43), and from High to Ultra costs 10 FPS (43 to 33). At 4K, the same preset ladder goes from 31 FPS (Low) to 21 FPS (Medium) to 18 FPS (High) to 13 FPS (Ultra). The fact that even the Low preset at 4K cannot approach 60 FPS shows that the GPU's raw throughput is the wall.

The CPU's capabilities, such as its 20655 Cinebench R23 multi-core score and 2916 single-core score, suggest it could push much higher frame rates in Rust if paired with a stronger GPU. However, with the Arc B390's 7.680 TFLOPS of FP32 performance and 60.00 GPixel/s pixel rate, the system is firmly GPU-limited in every measured configuration.

The Verdict

Based on the verdictByResolution data, this PC can run Rust at 1920x1080 with the Low preset, achieving an average of 76 FPS, which clears the 60 FPS playable threshold. This is the only playable configuration in the entire dataset. At 2560x1440, no settings preset reaches 60 FPS; the best option is Low at 53 FPS, which is playable but not smooth. At 3840x2160, even Low settings only manage 31 FPS, making 4K impractical for this game.

For competitive or fast-paced gameplay, the 1080p Low setting provides the only reliable experience above 60 FPS. The Medium preset at 1080p averages 51 FPS, which some players might find acceptable for a survival game, but it falls short of the defined playable threshold. The 1440p Low setting at 53 FPS is close but still under 60 FPS, and the frame pacing data from Medium presets suggests consistent delivery without severe stutters.

This is not a system for high-fidelity Rust. Players who prioritize visual quality over frame rate could run 1080p Medium at 51 FPS or 1440p Low at 53 FPS, but the data indicates that the GPU is too weak for anything beyond the lowest presets at mainstream resolutions.

How This Combo Ranks

In the database's combined rankings, this CPU-GPU pairing sits at rank 3312 out of 3723 tested combinations, placing it in the bottom 11% of all systems. This low ranking is driven almost entirely by the GPU, which is at the 9th percentile of all graphics cards. The CPU's 78th percentile ranking is wasted in this pairing, as the GPU cannot translate that processing power into frame rate.

The rank of 3312 out of 3723 means there are 411 tested combinations that perform worse, but the vast majority of systems in the database would deliver better Rust performance. For context, the GPU's nearest rivals are all over a decade old, and the Arc B390 only beats them by 1.3% to 2.7% in synthetic benchmarks. This is a bottom-tier gaming GPU, regardless of the CPU attached to it.
