Rust

The combination of the AMD Ryzen 7 5800XT and NVIDIA GeForce RTX 4090 delivers exceptional performance in Rust, with measured FPS data showing that this system can comfortably exceed the 60 FPS playability threshold at all tested resolutions. The data reveals a system that is heavily GPU-bound at lower resolutions, while the CPU’s 8-core/16-thread Zen 3 architecture becomes increasingly relevant at 4K, where the demand on the rendering pipeline shifts. This analysis breaks down the measured FPS, settings recommendations, and component roles based exclusively on the benchmark data provided.

Best Settings per Resolution

At 3840x2160 (4K), the most demanding preset that maintains an average FPS at or above 60 is High, delivering an average of 73.3 FPS. The Ultra preset falls short of the playability threshold at this resolution, averaging only 56.1 FPS, which is below the 60 FPS target. Low and Medium presets both clear the threshold, with averages of 129.8 FPS and 87.4 FPS, respectively, but High offers the best visual fidelity while remaining playable.

At 2560x1440 (1440p), the system can run Ultra settings while sustaining an average of 94.6 FPS, making it the recommended choice for maximum visual quality. All four presets—Low, Medium, High, and Ultra—produce averages above 60 FPS, with Low reaching 183.6 FPS, Medium at 144.7 FPS, and High at 123 FPS. The headroom at this resolution is substantial, allowing players to prioritize image quality without sacrificing smoothness.

At 1920x1080 (1080p), Ultra is again the best setting, achieving an average of 140.3 FPS. Every preset exceeds 60 FPS by a wide margin: Low averages 209.3 FPS, Medium 175.8 FPS, and High 166.1 FPS. The GPU’s raw throughput is more than sufficient at this resolution, and the limiting factor shifts toward CPU-bound game logic, though the Ryzen 7 5800XT’s single-thread performance (3,359 in Cinebench R23 single-core) keeps frame rates well above the threshold.

Measured FPS Breakdown

At 3840x2160, the measured average FPS values are as follows: Low settings produce 129.8 FPS, Medium 87.4 FPS, High 73.3 FPS, and Ultra 56.1 FPS. The scaling from Low to Ultra shows a 46% reduction in average FPS, with the largest single-step drop occurring between Medium and High (14.1 FPS) and between High and Ultra (17.2 FPS). No minimum or maximum FPS values are provided for any resolution.

At 2560x1440, the averages are: Low 183.6 FPS, Medium 144.7 FPS, High 123 FPS, and Ultra 94.6 FPS. The transition from Low to Medium costs 38.9 FPS, while Medium to High costs 21.7 FPS, and High to Ultra costs 28.4 FPS. The Ultra preset still maintains a 57% margin above the 60 FPS threshold.

At 1920x1080, the averages are: Low 209.3 FPS, Medium 175.8 FPS, High 166.1 FPS, and Ultra 140.3 FPS. The step from Low to Medium is 33.5 FPS, Medium to High is 9.7 FPS, and High to Ultra is 25.8 FPS. Notably, the Medium-to-High gap is the smallest across all resolutions, suggesting that at 1080p the visual quality increase from Medium to High has a relatively minor performance impact compared to other settings changes.

The data shows a consistent pattern: as resolution increases, the absolute FPS values drop across all presets, but the relative performance gap between Low and Ultra widens. At 1080p, Ultra achieves 67% of Low’s performance; at 1440p, it achieves 51%; and at 4K, it achieves 43%. This indicates that the GPU’s compute resources (82.58 TFLOPS FP32) are increasingly saturated at higher resolutions.

Similar Performance Alternatives

Based on the nearest rivals in the benchmark database, the CPU’s closest equivalents are all AMD processors with similar aggregate scores. The AMD Ryzen 7 7840H has an average score of 29,868, which is a 0% delta from the Ryzen 7 5800XT’s average benchmark score of 29,879. The AMD Ryzen 7 8845HS and AMD Ryzen 7 7840HS both score 29,955, representing a -0.3% delta, meaning they are marginally faster in synthetic tests. The AMD Ryzen 5 9600X scores 29,713, a +0.6% delta, indicating slightly lower aggregate performance. For gaming purposes, these differences are negligible, and any of these CPUs paired with the RTX 4090 would produce nearly identical FPS results in Rust, given that the GPU is the primary bottleneck at most settings.

On the GPU side, the nearest rivals are less conventional. The Intel Arc Pro A60 matches the RTX 4090’s average score of 60,347 exactly (0% delta), though this is likely a synthetic benchmark anomaly rather than a real-world gaming equivalency. The AMD Radeon Pro Vega 48 scores 60,140 (+0.3% delta), and the AMD Radeon Pro W6600M scores 61,896 (-2.5% delta), meaning the RTX 4090 is slightly ahead. The AMD Radeon PRO V710 scores 58,657 (+2.9% delta), indicating the RTX 4090 is about 3% faster in aggregate. In practice, none of these workstation or professional GPUs would match the RTX 4090’s gaming performance in Rust, but the benchmark data places them in the same score band.

How This Combo Ranks

The combination of the Ryzen 7 5800XT and RTX 4090 ranks 193rd out of 3,723 tested combos for Rust. This places the system in the top 5.2% of all configurations tested, which is consistent with the high-end nature of both components. The CPU’s percentile rank among all processors is 81st, indicating it outperforms 81% of tested CPUs. The GPU’s percentile rank is 88th, meaning it outperforms 88% of tested GPUs. The combo rank is lower than either component’s individual percentile, which suggests that some combinations with higher-ranked CPUs achieve better overall results in Rust, likely due to the game’s reliance on single-threaded performance for draw call processing and world updates.

The gap between the combo’s rank (193rd) and the GPU’s percentile (88th) indicates that the CPU is the limiting factor in achieving a top-100 rank. The Ryzen 7 5800XT’s Cinebench R23 multicore score of 23,794 and single-core score of 3,359 are strong, but newer CPUs with higher single-thread scores (e.g., the Ryzen 5 9600X, which has a +0.6% delta in aggregate but likely higher single-core performance) could push the combo higher.

The Verdict

This system can run Rust at playable frame rates across all tested resolutions and presets, with two exceptions: 4K Ultra settings, which average 56.1 FPS, fall below the 60 FPS threshold. At 4K, the best playable setting is High, averaging 73.3 FPS. At 1440p, all four presets—Low (183.6 FPS), Medium (144.7 FPS), High (123 FPS), and Ultra (94.6 FPS)—exceed 60 FPS, so players can use Ultra for maximum visual quality. At 1080p, all presets are comfortably playable, with Ultra averaging 140.3 FPS and Low reaching 209.3 FPS.

The verdict by resolution confirms that the system is fully capable for Rust: 4K users must compromise by dropping from Ultra to High, while 1440p and 1080p users can run the highest preset without issue. The measured data shows that the RTX 4090’s 24 GB of GDDR6X memory and 1.01 TB/s bandwidth handle the game’s textures effectively, while the Ryzen 7 5800XT’s 8 cores and 16 threads provide sufficient processing power for multiplayer server loads, which are not directly measured here but are inherent to Rust’s gameplay.

CPU and GPU Roles

The benchmark data reveals a clear division of labor between the CPU and GPU across resolutions. At 1920x1080, the GPU has ample headroom, as evidenced by the 209.3 FPS average at Low settings. The CPU’s single-thread performance (3,359 in Cinebench R23 single-core) becomes more relevant here, as the game’s logic and draw calls are more likely to be the limiting factor when the GPU is not saturated. The relatively small FPS drop from Medium to High (9.7 FPS) at 1080p, compared to the larger drop from High to Ultra (25.8 FPS), suggests that the Ultra preset introduces GPU-intensive effects that begin to tax the RTX 4090 even at this resolution.

At 2560x1440, the GPU’s workload increases, as shown by the wider spread between Low (183.6 FPS) and Ultra (94.6 FPS). The CPU still provides enough throughput to keep the GPU fed, but the scaling from Medium to High (21.7 FPS) and High to Ultra (28.4 FPS) indicates that the GPU is now the dominant factor in frame rate differences. The Ryzen 7 5800XT’s 16 threads (with a Passmark multithread score of 28,053) are sufficient to avoid bottlenecking at this resolution.

At 3840x2160, the GPU is unequivocally the limiting component. The Ultra preset averages 56.1 FPS, which is below the playable threshold, while the CPU’s performance does not change with resolution. The fact that Low settings at 4K (129.8 FPS) achieve nearly the same frame rate as Medium at 1440p (144.7 FPS) indicates that the GPU’s fill rate and memory bandwidth are the primary constraints. The RTX 4090’s pixel rate of 443.5 GPixel/s and texture rate of 1,290.2 GTexel/s are being pushed to their limits at 4K Ultra, while the CPU’s role diminishes to that of a supporting player, ensuring that game state updates and physics calculations keep pace with the rendering pipeline.

In summary, the CPU matters most at 1080p and 1440p where the GPU has headroom, while the GPU becomes the sole bottleneck at 4K. The data shows a 69 FPS difference between Low and Ultra at 1080p, a 89 FPS difference at 1440p, and a 73.7 FPS difference at 4K, which does not follow a simple linear scaling due to the CPU’s diminishing returns at higher resolutions. Players targeting 4K should prioritize GPU settings, while those at 1080p can benefit from a stronger CPU for frame rate stability in crowded servers.
