Rust

Measured FPS Breakdown

The recorded data for Rust on this AMD Ryzen 5 5600X and Intel Arc B370 combination shows a clear performance ceiling that scales directly with resolution. At 3840x2160, the highest measured average is 28 FPS on Low settings, while High drops to 16 FPS, Medium lands at 19 FPS with a minimum of 16 and maximum of 22, and Ultra falls to 12 FPS. The 4K results are uniformly below any playable threshold, with no setting producing a smooth experience.

Moving to 2560x1440, the numbers improve but remain constrained. Low settings deliver 48 FPS average, Medium reaches 32 FPS with a range of 27 to 37, High sits at 27 FPS, and Ultra bottoms out at 20 FPS. The gap between Low and Medium here is 16 FPS, which is substantial, but even the best case at 1440p falls short of the 60 FPS target.

At 1920x1080, the picture changes notably. Low settings achieve 69 FPS average, which is the only recorded result above the 60 FPS threshold in the entire dataset. Medium follows at 46 FPS with a minimum of 39 and maximum of 53, High reaches 39 FPS, and Ultra drops to 30 FPS. The spread from Low to Ultra at 1080p is 39 FPS, indicating that preset selection has a massive impact on this hardware.

The data reveals a consistent pattern: each resolution step down from 4K to 1440p to 1080p yields roughly a 1.7x to 1.75x improvement in average FPS at the same settings. For example, Low goes from 28 to 48 to 69 FPS across the three resolutions, while High goes from 16 to 27 to 39 FPS. This linear scaling suggests the system is heavily limited by the GPU rather than the CPU, as resolution changes directly affect the pixel throughput demand.

CPU and GPU Roles

The benchmark results indicate that the Intel Arc B370 is the dominant bottleneck in this pairing. The GPU's 3DMark Steel Nomad DX12 score of 1184 places it in the 5th percentile of all GPUs, which is extremely low. The CPU, by contrast, sits in the 75th percentile with an average benchmark score of 21771. This massive disparity in relative standing explains why resolution scaling has such a pronounced effect on FPS: the GPU is struggling to fill pixels, while the CPU has ample headroom to feed frames.

The scaling between presets reinforces this interpretation. At 1920x1080, dropping from Ultra (30 FPS) to Low (69 FPS) produces a 130% improvement. If the CPU were the limiting factor, this preset change would yield smaller gains because the CPU workload would remain similar. Instead, the large swings point to the GPU's shading units (1280), texture mapping units (40), and raster output units (20) being overwhelmed by higher-quality rendering features.

The GPU's memory configuration is described as "System Shared" with "System Dependent" bandwidth, which means it relies on the CPU's DDR4 memory in dual-channel mode at 51.2 GB/s. This shared memory architecture adds latency and reduces effective bandwidth compared to dedicated VRAM, further constraining the GPU in memory-intensive scenarios like Rust's large open world. The 25 W TDP for the GPU also suggests a power-limited design that cannot sustain high clocks under load, despite a 2400 MHz boost clock.

The CPU's role becomes more apparent when examining the 3DMark thread scaling scores. The Ryzen 5 5600X scores 917 in single-thread, 1793 in 2-thread, 3363 in 4-thread, 4811 in 8-thread, and 5588 in max-thread tests. Rust is known for heavy single-thread dependency, and the CPU's single-thread performance is strong relative to its rivals. However, the FPS data shows that even with a capable CPU, the GPU cannot deliver playable framerates at higher resolutions, which confirms the GPU-bound nature of the system.

Best Settings per Resolution

At 3840x2160, no preset achieves 60 FPS. The best recorded average is 28 FPS on Low settings, which is less than half the playable threshold. Medium, High, and Ultra all fall below 20 FPS. The database records no playable settings for 4K with this combination.

At 2560x1440, the situation is similar. No preset reaches 60 FPS. Low settings provide 48 FPS, which is the closest to the target, but it still misses by 12 FPS. Medium, High, and Ultra all remain in the 20 to 32 FPS range. The verdict data confirms that no playable settings exist at this resolution.

At 1920x1080, Low settings are the only playable option. The average FPS at Low is 69, which clears the 60 FPS threshold by 9 FPS. Medium falls short at 46 FPS, High at 39 FPS, and Ultra at 30 FPS. The database designates Low as the best settings for this resolution, as it is the most demanding preset that stays at or above 60 FPS. Players who want higher visual fidelity would need to accept framerates in the 30 to 46 FPS range, which may be tolerable for slower-paced gameplay but does not meet the playable standard.

How This Combo Ranks

The combination of AMD Ryzen 5 5600X and Intel Arc B370 ranks 3437 out of 3723 tested combos for Rust. This places it in the bottom 8% of all configurations, which is consistent with the low GPU percentile. The rank reflects the GPU's severe performance limitation rather than any deficiency in the CPU, as the CPU alone performs well in synthetic benchmarks.

The 3723 total combos represent a wide range of hardware pairings, and this specific combo's position indicates that most other configurations deliver better Rust performance. The GPU's 5th percentile standing among all GPUs is the primary driver of this low rank. Even a mid-range GPU from several generations ago would likely outperform the Arc B370 based on the nearest rival data, which shows the GPU scoring close to legacy parts like the ATI Radeon HD 5770.

The CPU's 75th percentile ranking means that if this processor were paired with a more capable GPU, the combo rank would improve dramatically. The bottleneck is unambiguous: the GPU is holding back an otherwise solid CPU. The data suggests that this pairing is fundamentally unbalanced for gaming, particularly for a demanding title like Rust.

Similar Performance Alternatives

Looking at the nearest rivals for the CPU, the AMD Ryzen 5 5600X is closely matched by the AMD Ryzen 7 4800H, which scores 21749 versus 21771, a delta of 0.1%. This means the Ryzen 7 4800H would perform nearly identically in CPU-bound scenarios. The AMD Ryzen 5 PRO 6650U scores 21874 (delta -0.5%), the Intel Core i7-11700 scores 21891 (delta -0.5%), and the AMD EPYC 9554P scores 21899 (delta -0.6%). All of these CPUs are within 0.6% of the 5600X in average benchmark score, so any of them paired with the same GPU would yield essentially the same Rust framerates, as the GPU remains the limiting factor.

For the GPU, the nearest rivals are all legacy or low-end parts. The ATI Mobility Radeon HD 5570 scores 1186 versus the Arc B370's 1184, a delta of -0.2%. The ATI Radeon HD 5770 scores 1190 (delta -0.5%), the AMD Radeon HD 7650M scores 1192 (delta -0.7%), and the AMD FirePro M2000 scores 1168 (delta 1.4%). These deltas are all within 1.4%, meaning any of these GPUs would produce nearly identical Rust performance. The close scores indicate that the Arc B370 is not a meaningful step up from hardware that is over a decade old, which explains the poor gaming results.

The Verdict

This PC cannot run Rust satisfactorily at 3840x2160 or 2560x1440 under any settings. At 4K, the highest average FPS is 28 on Low, and at 1440p, the highest is 48 on Low. Neither meets the 60 FPS playable threshold.

At 1920x1080, the system clears the bar with 69 FPS on Low settings. This is the only playable configuration in the entire dataset. The verdict data confirms that Low is the best settings option at 1080p, with no other preset reaching 60 FPS.

The broader implications are clear: the Intel Arc B370 is a severe performance bottleneck that prevents this otherwise capable Ryzen 5 5600X from delivering acceptable gaming performance in Rust. The combo ranks 3437 out of 3723 tested configurations, placing it near the bottom. For anyone considering this pairing, the data suggests that the GPU should be replaced with a more capable model to unlock the CPU's potential. As it stands, this system is only suitable for 1080p gaming at minimum settings, and even then, the experience will be limited to the lowest visual quality preset.
