Rust

The AMD Ryzen 9 9900X and Intel Arc B370 combination delivers playable performance in Rust only at 1920x1080 with Low settings, where it averages 69 FPS. All other tested resolution and preset combinations fall below the 60 FPS threshold, with 4K and 1440p results ranging from 12 to 48 FPS. The data indicates a severe GPU bottleneck: the Arc B370, an integrated-class part with a 5th percentile ranking among all GPUs, limits this system far more than the high-end Ryzen 9 9900X CPU.

Measured FPS Breakdown

At 3840x2160 (4K), Rust runs poorly across all presets. The Low preset delivers an average of 28 FPS, while Medium drops to 19 FPS with a minimum of 16 and a maximum of 22. High averages 16 FPS, and Ultra falls to 12 FPS. No 4K preset approaches the 60 FPS playable threshold; the gap ranges from 32 FPS (Low) to 48 FPS (Ultra) below the target.

At 2560x1440 (1440p), performance improves but remains sub-60 FPS in every configuration. Low averages 48 FPS, which is 12 FPS short of playable. Medium averages 32 FPS, with a recorded range of 27 to 37 FPS. High averages 27 FPS, and Ultra averages 20 FPS. The scaling from 4K to 1440p shows a consistent improvement: Low gains 20 FPS (from 28 to 48), Medium gains 13 FPS (from 19 to 32), High gains 11 FPS (from 16 to 27), and Ultra gains 8 FPS (from 12 to 20). This pattern indicates that lowering resolution directly relieves pressure on the GPU, but even at 1440p the Arc B370 cannot sustain fluid frame rates.

At 1920x1080 (1080p), the Low preset finally crosses the 60 FPS line with an average of 69 FPS. Medium averages 46 FPS, with a minimum of 39 and a maximum of 53. High averages 39 FPS, and Ultra averages 30 FPS. The jump from 1440p Low (48 FPS) to 1080p Low (69 FPS) represents a 21 FPS gain, the largest single-step improvement across all tested settings. The Medium preset at 1080p shows a minimum of 39 FPS, meaning even during dips, the frame rate stays above the 4K Low average. The data shows that 1080p Low is the only configuration in the entire measurement set that meets the 60 FPS playability criterion.

CPU and GPU Roles

The benchmark results clearly identify the Intel Arc B370 as the dominant limiting factor. The GPU's average benchmark score is 1184 in 3DMark Steel Nomad DX12, placing it in the 5th percentile of all GPUs. Its nearest rivals include the ATI Mobility Radeon HD 5570 (score 1186, 0.2% faster), ATI Radeon HD 5770 (score 1190, 0.5% faster), and AMD Radeon HD 7650M (score 1192, 0.7% faster). These are legacy or low-end mobile parts from over a decade ago, confirming that the Arc B370 operates in a performance class far below modern desktop discrete GPUs.

The CPU, by contrast, is a top-tier desktop processor. The Ryzen 9 9900X scores 57,498 on average across all benchmarks, ranking in the 92nd percentile of all CPUs. Its nearest rivals include the AMD EPYC 9015 (score 57,555, 0.1% faster), AMD EPYC 7313 (score 57,399, 0.2% slower), Intel Core i9-14900 (score 58,115, 1.1% faster), and Intel Xeon Platinum 8260M (score 58,323, 1.4% faster). With 12 cores, 24 threads, and a boost clock of 5.60 GHz, the Ryzen 9 9900X provides ample compute headroom for Rust's simulation and world-generation tasks.

The resolution scaling data proves the GPU bottleneck. When moving from 1080p to 1440p, average FPS drops by roughly 30% across presets (e.g., Low from 69 to 48, Medium from 46 to 32). From 1440p to 4K, the drop continues (Low from 48 to 28, Medium from 32 to 19). If the CPU were the limiting factor, reducing resolution would yield minimal FPS gains because the CPU workload per frame would remain similar. Instead, the substantial FPS improvements at lower resolutions indicate that pixel throughput and fill rate, both GPU functions, constrain the system. The Ryzen 9 9900X's single-thread performance (3DMark single-thread score of 1286, Cinebench R23 single-core score of 2253) is more than sufficient for Rust's typical CPU demands; the GPU simply cannot keep pace.

Similar Performance Alternatives

For the CPU, the nearest rivals in the database are all server or high-end desktop parts with average scores within 1.5% of the Ryzen 9 9900X's 57,498. The AMD EPYC 9015 (57,555) is 0.1% faster, making it statistically identical in multi-threaded workloads. The AMD EPYC 7313 (57,399) is 0.2% slower, also effectively equivalent. The Intel Core i9-14900 (58,115) is 1.1% faster, and the Intel Xeon Platinum 8260M (58,323) is 1.4% faster. These differences are negligible in real-world gaming, meaning any of these CPUs paired with the same GPU would produce nearly identical FPS results in Rust, since the GPU remains the bottleneck.

For the GPU, the nearest rivals are dramatically lower-performing parts. The ATI Mobility Radeon HD 5570 (1186) is 0.2% faster, the ATI Radeon HD 5770 (1190) is 0.5% faster, and the AMD Radeon HD 7650M (1192) is 0.7% faster. The AMD FirePro M2000 (1168) is 1.4% slower. These rivals all fall within a 2% performance band, so swapping the Arc B370 for any of them would yield nearly identical FPS in Rust. This cluster of low-end GPUs confirms that the Arc B370's 6.144 TFLOPS FP32 compute and 20 ROPs place it in a performance tier where even a modest increase in GPU capability would meaningfully improve frame rates, but the system as configured cannot leverage the CPU's strength.

The Verdict

The recorded data shows that this PC can run Rust at 1920x1080 with Low settings, achieving an average of 69 FPS, which clears the 60 FPS playable threshold. At 2560x1440, no preset reaches 60 FPS; the best result is Low at 48 FPS, which is 12 FPS short. At 3840x2160, performance is unplayable across the board, with Low at 28 FPS, Medium at 19 FPS, High at 16 FPS, and Ultra at 12 FPS. The verdict is unambiguous: this combination is suitable only for 1080p gaming at the lowest preset. Any attempt to raise settings or resolution will result in frame rates below the playable threshold, with the GPU being the primary cause. The system's high-end CPU cannot compensate for the GPU's limited fill rate and shading power.

Best Settings per Resolution

At 3840x2160, no preset meets the 60 FPS requirement. The highest average FPS is 28 at Low, but that is still 32 FPS below playable. The database records no "best settings" for 4K because the playable threshold is unattainable.

At 2560x1440, similarly, no preset reaches 60 FPS. Low averages 48 FPS, which is the best recorded result, but it falls 12 FPS short of the threshold. Medium (32 FPS), High (27 FPS), and Ultra (20 FPS) are all worse. The database lists no playable settings at this resolution.

At 1920x1080, the Low preset is the only playable configuration, averaging 69 FPS. Medium averages 46 FPS, which is below the 60 FPS threshold, and High (39 FPS) and Ultra (30 FPS) are progressively worse. The recommended setting is therefore Low at 1080p, where the average FPS of 69 provides a modest 9 FPS margin above the playable line. The minimum FPS for this preset is not recorded, but the average suggests consistent performance above the threshold.

How This Combo Ranks

The combination of the Ryzen 9 9900X and Intel Arc B370 ranks 3437 out of 3723 tested combos in Rust, placing it in the bottom 8% of all systems in the database. This low rank reflects the severe mismatch between the CPU and GPU. The Ryzen 9 9900X's 92nd percentile CPU ranking would normally support high frame rates, but the Arc B370's 5th percentile GPU ranking drags the entire system down. In Rust, which is a GPU-bound title at most settings due to its large draw distances and complex lighting, the GPU's limitations dominate the final result.

The rank of 3437 out of 3723 means that more than 92% of tested combinations deliver better performance in Rust. This places the system firmly in the low-performance tier, comparable to systems from several years ago rather than contemporary gaming rigs. The data indicates that even the weakest modern desktop GPUs would likely outperform this combination, given that the Arc B370's nearest rivals are all legacy parts. For Rust specifically, the combo's inability to exceed 48 FPS at 1440p Low or 30 FPS at 1080p Ultra confirms its position near the bottom of the database's performance distribution.
