Rust

Measured FPS Breakdown

The recorded data for Rust on this AMD Ryzen 7 9800X3D plus Intel Arc B370 combination shows a clear pattern: playable frame rates only appear at 1080p with the lowest settings, while higher resolutions and presets fall well short of the 60 FPS threshold.

At 1920x1080, the Low preset delivers an average of 69 FPS, which is the only configuration in the entire dataset that clears the playable benchmark of 60 FPS. The Medium preset at 1080p drops to an average of 46 FPS, with a recorded minimum of 39 FPS and maximum of 53 FPS. High settings at 1080p average 39 FPS, while Ultra averages just 30 FPS. The scaling from Low to Ultra at this resolution is steep, with a 39 FPS drop between the two extremes, representing a 56.5% reduction in average frame rate.

Moving to 2560x1440, the results become more constrained. The Low preset averages 48 FPS, which is playable in a loose sense but still below the 60 FPS target. Medium averages 32 FPS with a minimum of 27 FPS and maximum of 37 FPS. High settings average 27 FPS, and Ultra averages 20 FPS. The gap between Low and Ultra at 1440p is 28 FPS, showing that even the most aggressive settings reduction cannot bring this combination near the playable threshold.

At 3840x2160, the situation is challenging. Low settings average 28 FPS, Medium averages 19 FPS with a minimum of 16 FPS and maximum of 22 FPS, High averages 16 FPS, and Ultra averages 12 FPS. None of these configurations come close to 60 FPS, and even the fastest preset at 4K delivers less than half the required frame rate.

The data shows that min and max FPS values were only recorded for the Medium preset at each resolution. At 1080p Medium, the 39 FPS minimum and 53 FPS maximum bracket the 46 FPS average tightly, suggesting relatively consistent frame pacing. At 1440p Medium, the 27 FPS minimum and 37 FPS maximum show a similar spread. At 4K Medium, the 16 FPS minimum and 22 FPS maximum indicate that even the best-case frame times remain far below playability.

CPU and GPU Roles

The benchmark results indicate that the Intel Arc B370 is the dominant bottleneck in this pairing, particularly as resolution scales upward. The Ryzen 7 9800X3D is a high-end desktop processor with 8 cores, 16 threads, and 96 MB of shared L3 cache, but the GPU's position in the 5th percentile of all GPUs means it cannot translate that CPU horsepower into frame rate.

The resolution scaling tells a clear story. From 1080p Low to 1440p Low, the average FPS drops from 69 to 48, a 30.4% reduction. From 1440p Low to 4K Low, the average drops from 48 to 28, another 41.7% reduction. This consistent degradation across resolutions points to the GPU being the limiting factor, as the CPU workload in Rust at these settings is unlikely to change dramatically with resolution, while the pixel fill rate requirements scale directly.

The settings scaling reinforces this interpretation. At 1080p, moving from Low to Medium costs 23 FPS (from 69 to 46), then another 7 FPS going to High (from 46 to 39), and another 9 FPS going to Ultra (from 39 to 30). The GPU's limited shading units (1280) and ROPs (20) mean that each incremental increase in visual fidelity extracts a proportionally large toll on frame rate.

The CPU's role is diminished in this configuration. The Ryzen 7 9800X3D scores 23,230 in Cinebench R23 multi-core and 2,080 in single-core, placing it in the 87th percentile of all CPUs. Its nearest rivals, such as the AMD Ryzen 7 7700 with an average score of 40,081, are within 0.8% of its aggregate benchmark. This level of CPU performance is far beyond what the Arc B370 can feed, so the recorded frame rates reflect GPU limits, not CPU potential.

At 4K, the GPU's weakness becomes even more pronounced. The Arc B370's 6.144 TFLOPS FP32 throughput and 48.00 GPixel/s pixel rate are simply insufficient for Rust's large open-world rendering at high resolution. The fact that the best 4K result (28 FPS on Low) is still below the 1440p Medium result (32 FPS) shows how quickly the GPU saturates as pixel count increases.

FAQ

Q: Can this PC run Rust at 1080p with playable frame rates?

A: Yes, but only at the Low preset. The 1920x1080 Low configuration averages 69 FPS, which clears the 60 FPS playable threshold. Medium settings average 46 FPS, High averages 39 FPS, and Ultra averages 30 FPS, all of which fall short.

Q: What is the best settings preset at 1440p for this combination?

A: The verdict data indicates no playable settings at 2560x1440. The best average FPS at this resolution is 48 on Low, which is still below the 60 FPS threshold. Medium averages 32 FPS, High averages 27 FPS, and Ultra averages 20 FPS.

Q: How does the frame rate scale from 1080p to 4K on the same settings?

A: On Low settings, the average FPS drops from 69 at 1080p to 48 at 1440p to 28 at 4K. This represents a 59.4% reduction from 1080p to 4K on the same preset, highlighting the GPU's steep performance curve as resolution increases.

Q: Is the Ryzen 7 9800X3D the bottleneck in this system for Rust?

A: No, the data indicates the GPU is the limiting factor. The CPU scores in the 87th percentile of all CPUs, while the GPU sits in the 5th percentile. The frame rate drops consistently with resolution and settings increases, which is characteristic of GPU-bound performance.

Q: What frame rates can be expected at 4K with Medium settings?

A: The 3840x2160 Medium preset averages 19 FPS, with a minimum of 16 FPS and maximum of 22 FPS. This is the only 4K preset with recorded min/max values, and none of the 4K presets approach the 60 FPS playable threshold.

Q: Does the Ultra preset ever reach playable frame rates?

A: No. The Ultra preset averages 30 FPS at 1080p, 20 FPS at 1440p, and 12 FPS at 4K. None of these results come within 50% of the 60 FPS threshold, making Ultra settings impractical for this combination at any resolution.

The Verdict

The database verdict is clear: this combination can run Rust at 1920x1080 with the Low preset, achieving 69 FPS average. That is the only resolution and settings configuration that clears the 60 FPS playable threshold. At 2560x1440, no settings preset reaches 60 FPS, with the best result being 48 FPS on Low. At 3840x2160, the situation is worse, with the best result being 28 FPS on Low.

For players who prioritize frame rate over visual fidelity, the 1080p Low configuration is the only viable option. The 69 FPS average provides a comfortable margin above the playable threshold, though it leaves no headroom for demanding in-game moments. The 46 FPS average at 1080p Medium is technically playable in a relaxed sense, but it does not meet the database's 60 FPS standard.

The verdict data explicitly lists no playable settings for 1440p or 4K. This means that anyone using this combination for Rust at higher resolutions will need to accept frame rates well below the playable threshold. The best settings preset at 1440p is Low at 48 FPS, and at 4K it is also Low at 28 FPS, but both fail the 60 FPS requirement.

Similar Performance Alternatives

The nearest rivals for the Ryzen 7 9800X3D are all AMD processors with similar aggregate benchmark scores. The AMD Ryzen 7 PRO 8840HS averages 39,603 points, just 0.4% below the 9800X3D's 39,768 average. The AMD Ryzen AI 9 365 averages 40,048 points, 0.7% higher. The AMD Ryzen AI 7 450 averages 39,485 points, 0.7% lower. The AMD Ryzen 7 7700 averages 40,081 points, 0.8% higher. In practice, any of these CPUs would behave nearly identically in Rust when paired with the same GPU, since the GPU is the limiting factor.

The Intel Arc B370's nearest rivals are significantly older graphics solutions. The ATI Mobility Radeon HD 5570 averages 1,186 points, 0.2% higher than the Arc B370's 1,184. The ATI Radeon HD 5770 averages 1,190 points, 0.5% higher. The AMD Radeon HD 7650M averages 1,192 points, 0.7% higher. The AMD FirePro M2000 averages 1,168 points, 1.4% lower. These deltas are all within 1.4%, meaning the Arc B370 would produce nearly identical Rust frame rates to these legacy parts, all of which are similarly constrained.

For players considering alternatives, the CPU side offers several options that would not change the gaming outcome. Swapping the Ryzen 7 9800X3D for any of its nearest rivals would leave the frame rates essentially unchanged, since the Arc B370's 5th percentile GPU standing is the binding constraint. The GPU side is where meaningful change would need to occur, but the nearest rivals listed are all in the same performance class, so none would meaningfully improve Rust performance.

How This Combo Ranks

The AMD Ryzen 7 9800X3D plus Intel Arc B370 combination ranks 3,437 out of 3,723 tested combos in the database for Rust. This places it in the bottom 7.7% of all tested system configurations, reflecting the severe mismatch between the high-end CPU and the entry-level GPU.

The rank makes sense given the measured data. With only one playable configuration (1080p Low at 69 FPS), this combo sits far below the majority of tested systems that can handle higher resolutions or settings. The 286 combos ranked below this one would be expected to perform worse, likely falling below even the 1080p Low result or failing to reach playable frame rates at any setting.

The CPU's 87th percentile ranking does not help the overall combo position, because the GPU's 5th percentile ranking drags the combined score down. In Rust, where the GPU handles the bulk of rendering work, the CPU's strength is largely wasted. The benchmark results show that even at 1080p Low, the frame rate is only 69 FPS, which is modest for a system with a top-tier gaming CPU.

This rank signals that the Intel Arc B370 is the component to replace if higher performance is desired. The Ryzen 7 9800X3D provides ample CPU headroom for future GPU upgrades, but as configured, this system is only suitable for 1080p Low gaming in Rust, and even that is a marginal result given the hardware's theoretical capabilities.
