Rust

AMD Ryzen 7 5800X3D and Intel Arc B370, when paired together, deliver a very limited experience in Rust. The data shows that this combination struggles significantly at higher resolutions, and only becomes playable at the lowest settings in 1080p. The following analysis breaks down the recorded performance metrics for this specific CPU and GPU pairing.

Best Settings per Resolution

The benchmark data for this combo shows a clear pattern: higher resolutions and more demanding presets push the frame rate well below the 60 FPS playable threshold. The recorded measurements provide specific average FPS figures for each tested setting and resolution.

At 3840x2160, no preset achieves a playable frame rate. The best result comes from the Low preset, which averages 28 FPS. The Medium preset averages 19 FPS, with a recorded minimum of 16 FPS and a maximum of 22 FPS. High averages 16 FPS, and Ultra drops to 12 FPS. None of these settings come close to the 60 FPS target, so the recommendation is that this resolution is not viable for smooth gameplay with this hardware combination.

At 2560x1440, the situation improves slightly but remains below the playable threshold. The Low preset averages 48 FPS, which is the highest recorded value at this resolution. Medium averages 32 FPS, with a minimum of 27 FPS and a maximum of 37 FPS. High averages 27 FPS, and Ultra averages 20 FPS. Since 48 FPS is still below 60, no settings at this resolution can be recommended for a smooth experience.

At 1920x1080, the Low preset finally crosses the 60 FPS mark, averaging 69 FPS. This is the only configuration that achieves a playable frame rate. The Medium preset averages 46 FPS, with a minimum of 39 FPS and a maximum of 53 FPS. High averages 39 FPS, and Ultra averages 30 FPS. The best settings per resolution are therefore: for 3840x2160, no playable settings exist; for 2560x1440, no playable settings exist; and for 1920x1080, the Low preset at 69 FPS is the only viable option.

CPU and GPU Roles

The recorded FPS data reveals how the workload shifts between the CPU and GPU as resolution changes. In this pairing, the Intel Arc B370 is an integrated graphics solution with a 25 W TDP and system-shared memory, which means it relies heavily on the CPU for memory access and overall system performance. The AMD Ryzen 7 5800X3D, with 8 cores and 16 threads based on Zen 3 architecture, provides strong processing power, but the GPU becomes the limiting factor in most scenarios.

Looking at the scaling between 1080p and 1440p, the frame rates drop consistently across all presets when resolution increases. For example, the Low preset falls from 69 FPS at 1920x1080 to 48 FPS at 2560x1440, a reduction of about 30%. The High preset drops from 39 FPS to 27 FPS, which is a similar proportional decline. This behavior indicates that the GPU is the primary constraint, as increasing the pixel count directly reduces the fill rate available.

The scaling from 1440p to 4K continues this trend. The Low preset drops from 48 FPS to 28 FPS, and Medium falls from 32 FPS to 19 FPS. The GPU's pixel rate of 48.00 GPixel/s and texture rate of 96.00 GTexel/s are simply insufficient for the demands of 4K rendering in Rust. The CPU, with its high single-thread score of 3234 in Passmark and multi-thread score of 28309, is not the bottleneck at these resolutions; the GPU's limited shader units (1280) and ROPs (20) cannot sustain higher output.

At 1080p, the CPU begins to matter more relative to the GPU, but the data still shows GPU limitation. The jump from Low (69 FPS) to Medium (46 FPS) is a 33% drop, while the jump from Medium to High (39 FPS) is only 15%. This suggests that the CPU can feed the GPU adequately at lower settings, but the GPU's processing capacity caps the frame rate. The CPU's 96 MB of shared L3 cache helps with game logic and world simulation, which is why the frame rates remain somewhat stable at 1080p, but the GPU's FP32 performance of 6.144 TFLOPS is too weak for higher presets.

The recorded minimum FPS values for Medium at each resolution (16 FPS at 4K, 27 FPS at 1440p, 39 FPS at 1080p) show that frame pacing becomes more erratic as resolution increases. This further points to the GPU as the limiting factor, as the CPU's 3DMark max threads score of 7285 indicates it can handle the game's threaded workload without severe dips.

How This Combo Ranks

In the database of tested combinations for Rust, this pairing of AMD Ryzen 7 5800X3D and Intel Arc B370 ranks 3437 out of 3723 total combos. This places it in the bottom 8% of all tested systems, indicating that it is a very weak configuration for this game. The percentile ranking for the CPU alone is 80, meaning the processor outperforms 80% of all CPUs in the database, but the GPU sits at the 5th percentile, meaning it outperforms only 5% of all GPUs. This mismatch highlights the severe bottleneck created by the integrated graphics solution.

The combo rank reflects the overall experience: with only one playable setting across all resolutions and presets, this system is far below what most other tested configurations achieve. The 3437th position out of 3723 combos means that the vast majority of other hardware pairings deliver higher frame rates in Rust. The data shows that the CPU is capable, but the GPU drags the entire system down to a level where only the lowest settings at the lowest resolution can reach the 60 FPS threshold.

Similar Performance Alternatives

The database provides nearest rival comparisons for both the CPU and GPU, which helps contextualize what other hardware would behave similarly.

For the CPU, the AMD Ryzen 7 5800X3D has an average benchmark score of 27896. Its closest rivals include the AMD Ryzen 7 6800U (average score 27887, virtually identical), the Intel Core i9-10900K (average score 27872, 0.1% slower), the AMD Ryzen AI 5 PRO 340 (average score 27932, 0.1% faster), and the Intel Core i5-12600KF (average score 27799, 0.3% slower). These differences are negligible, meaning a system using any of these CPUs would produce nearly identical CPU-bound performance in Rust. However, since the GPU is the limiting factor in this combo, swapping the CPU for one of these rivals would not change the overall frame rates meaningfully.

For the GPU, the Intel Arc B370 has an average benchmark score of 1184, based on a single 3DMark Steel Nomad DX12 test. Its nearest rivals are the ATI Mobility Radeon HD 5570 (average score 1186, 0.2% faster), the ATI Radeon HD 5770 (average score 1190, 0.5% faster), the AMD Radeon HD 7650M (average score 1192, 0.7% faster), and the AMD FirePro M2000 (average score 1168, 1.4% slower). These GPUs are all from older generations or lower tiers, and they would all deliver similar frame rates in Rust when paired with a strong CPU. The performance deltas are within a couple of percentage points, so any of these alternatives would produce nearly identical results in the game.

If a user were to substitute the CPU with one of its rivals, the frame rates would remain essentially unchanged because the GPU is the bottleneck. Conversely, substituting the GPU with one of its rivals would also yield similar results, since they all cluster around the same benchmark score. The only way to improve performance would be to use a significantly stronger GPU, which the nearest rival data does not indicate.

FAQ

A: The recorded data shows an average of 32 FPS at 2560x1440 with Medium settings, with a minimum of 27 FPS and a maximum of 37 FPS. This is well below the 60 FPS playable threshold.

The Verdict

The data clearly answers the question of whether this PC can run Rust. The combination of AMD Ryzen 7 5800X3D and Intel Arc B370 is only playable at 1920x1080 with the Low preset, where it achieves an average of 69 FPS. At every other resolution and preset combination, the frame rates fall below the 60 FPS threshold.

At 3840x2160, no settings are playable. The best result is 28 FPS on Low, with Medium at 19 FPS, High at 16 FPS, and Ultra at 12 FPS. At 2560x1440, no settings are playable either. The best result is 48 FPS on Low, with Medium at 32 FPS, High at 27 FPS, and Ultra at 20 FPS. These are all significant shortfalls from the target.

The verdict by resolution confirms this: for 3840x2160, there are no playable settings; for 2560x1440, there are no playable settings; and for 1920x1080, only the Low preset at 69 FPS clears the threshold. This system can technically run Rust, but only in a very limited configuration. Gamers who want to play at medium or high settings, or at higher resolutions, would need a more powerful GPU than the Intel Arc B370, as the CPU is not the limiting factor. The measured data shows this is a low-end experience overall, suitable only for 1080p gaming with the lowest graphical fidelity.
