Rust

The data presents a clear picture of how the AMD Ryzen 5 5600X and NVIDIA GeForce RTX 3080 Ti handle Rust across common resolutions. The measured FPS shows a predictable scaling pattern, but the magnitude of the drops between settings reveals where the performance bottleneck lies. From 1080p to 4K, the frame rate changes are substantial, indicating that the graphics card is the primary driver of performance at higher resolutions, while the CPU’s capability becomes more apparent at lower settings.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 produces a significant, consistent reduction in frame rates across all settings. At Low settings, the average FPS drops from 194.5 at 1080p to 155.5 at 1440p, then to 90 at 4K. This represents a 53.7% decrease in performance from 1080p to 4K, which is a steep curve. The scaling at Medium settings follows a similar pattern, falling from 154 at 1080p to 105.3 at 1440p, and finally to 59.7 at 4K, a 61.2% reduction. High settings see a drop from 126.5 at 1080p to 87.3 at 1440p and 51.1 at 4K, a 59.6% decrease. Ultra settings are the most demanding, with frame rates falling from 95.4 at 1080p to 67.6 at 1440p and 38.8 at 4K, a 59.3% reduction.

The steep decline between 1440p and 4K is particularly telling. For instance, at High settings, the frame rate drops by 36.2 FPS when moving from 1440p to 4K, while the drop from 1080p to 1440p is 39.2 FPS. This suggests that the GPU is becoming the limiting factor as pixel count increases, with the RTX 3080 Ti’s 12 GB of memory and 912.4 GB/s bandwidth being taxed heavily. The data indicates that at 4K, the system is firmly GPU-bound, as the performance difference between Low and Ultra settings is much larger than at 1080p, where the CPU has more headroom to influence results.

FAQ

Q: What is the highest average frame rate recorded for this combination in Rust?

A: The highest average FPS is 194.5, achieved at 1920x1080 resolution with Low settings.

Q: How much slower is 4K Ultra compared to 1080p Low?

A: The 4K Ultra preset produces an average of 38.8 FPS, which is 155.7 FPS lower than the 1080p Low result of 194.5 FPS.

Q: Is the performance gap between Medium and High settings larger at 1080p or 4K?

A: At 1080p, the gap is 27.5 FPS (from 154 to 126.5). At 4K, the gap narrows to 8.6 FPS (from 59.7 to 51.1), showing that the GPU struggles to differentiate between these settings at higher resolutions.

Q: Does the RTX 3080 Ti’s memory bandwidth appear to be a limiting factor in Rust?

Q: What is the percentile ranking of the RTX 3080 Ti compared to all GPUs?

A: The RTX 3080 Ti ranks in the 83rd percentile, with an average benchmark score of 41224, placing it well above the median but slightly behind the RTX 3090.

Q: How does the Ryzen 5 5600X’s single-thread performance compare to its multi-thread performance in synthetic tests?

A: The CPU scores 2622 in Cinebench R23 single-core and 18578 in multi-core, showing a strong single-thread capability that is crucial for Rust’s simulation logic.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in this configuration, and its specifications directly correlate with the measured FPS. The GPU features 12 GB of GDDR6X memory on a 384-bit bus, delivering 912.4 GB/s of bandwidth. This memory subsystem is critical for Rust’s large, persistent world, as texture streaming and asset loading are heavily dependent on bandwidth. The benchmark results show that at 4K, the GPU’s memory bandwidth becomes a bottleneck, as frame rates struggle to maintain fluidity on higher presets.

The GPU’s clock speeds also play a role. With a base clock of 1365 MHz and a boost clock of 1665 MHz, the RTX 3080 Ti is capable of high sustained performance. However, the data reveals that these clocks are not enough to overcome the demands of 4K Ultra, where the average FPS falls to 38.8. This is a significant drop from the 51.1 FPS at 4K High, indicating that the Ultra preset introduces rendering effects that heavily tax the GPU’s 10240 shading units and 112 ROPs. The GPU’s pixel rate of 186.5 GPixel/s and texture rate of 532.8 GTexel/s are substantial, but the 4K Ultra settings likely require more fill rate than the card can provide for this title.

The GPU’s position relative to rivals is informative. The data shows it is 0.5% behind the RTX 3090 in average benchmark score, yet the RTX 3080 Ti is designed to be a high-end solution. In Rust, the GPU’s performance is further evidenced by its Passmark G3D score of 26896, which is a strong indicator of its gaming capabilities. The measured FPS at 1080p Low (194.5) shows that the GPU is not the limiting factor at lower resolutions, but at 4K, its architectural limits are exposed.

Settings Recommendations

The measured data provides a clear hierarchy for selecting the optimal preset based on resolution and desired frame rate. For 1920x1080, the Low preset delivers the highest average FPS at 194.5, which is ideal for competitive play or high-refresh-rate monitors. However, the Medium preset at 154 FPS offers a better balance between visual fidelity and performance, as the 40.5 FPS drop from Low may be acceptable for most users. The High preset at 126.5 FPS is still playable and provides a more detailed image, while Ultra at 95.4 FPS is the most visually demanding but still above 60 FPS.

At 2560x1440, the Low preset is the only option that exceeds 144 FPS, achieving 155.5. The Medium preset at 105.3 FPS is the sweet spot for a standard 100Hz monitor, providing good visual quality without sacrificing smoothness. High at 87.3 FPS is suitable for 60Hz displays, but Ultra at 67.6 FPS may produce noticeable stutter on some panels. For 3840x2160, the data suggests that Low is the only viable preset for competitive play, with 90 FPS. Medium at 59.7 FPS is borderline for 60Hz monitors, while High at 51.1 FPS and Ultra at 38.8 FPS are not recommended for smooth gameplay. Based on the scores, the Medium preset at 1440p provides the best overall experience, balancing visual fidelity with a frame rate that remains comfortably above 100 FPS.

Measured FPS Breakdown

The measured FPS data is consistent across all resolutions, with a clear trend of decreasing performance as settings increase. At 1920x1080, the Low preset achieves 194.5 FPS, Medium reaches 154 FPS, High drops to 126.5 FPS, and Ultra falls to 95.4 FPS. The differences between presets are significant, with a 99.1 FPS gap between Low and Ultra. At 2560x1440, the same pattern holds: Low produces 155.5 FPS, Medium 105.3 FPS, High 87.3 FPS, and Ultra 67.6 FPS. The gap between Low and Ultra narrows to 87.9 FPS, showing that the GPU is becoming more constrained.

At 3840x2160, the performance drops are more pronounced. Low yields 90 FPS, Medium 59.7 FPS, High 51.1 FPS, and Ultra 38.8 FPS. The gap between Low and Ultra is 51.2 FPS, which is the smallest absolute difference but represents a 51.2% reduction in frame rate. This indicates that at 4K, the GPU is the sole bottleneck, as even the Low preset cannot maintain high triple-digit frame rates. The data also shows that the jump from Medium to High at 4K results in a 8.6 FPS drop, while the jump from High to Ultra results in a 12.3 FPS drop, suggesting that Ultra settings introduce effects that are disproportionately expensive at this resolution.

CPU Role

The AMD Ryzen 5 5600X plays a crucial role in Rust, particularly at lower resolutions where the GPU is not the primary bottleneck. The CPU has 6 cores and 12 threads, with a base clock of 3.70 GHz and a boost clock of 4.60 GHz. Its architecture, Zen 3, provides strong single-thread performance, which is essential for Rust’s server-side simulation and physics calculations. The Cinebench R23 single-core score of 2622 and multi-core score of 18578 demonstrate a capable processor, but the data suggests that Rust does not fully utilize all 12 threads.

The CPU’s performance is most evident at 1080p Low, where the frame rate of 194.5 FPS is likely limited by the CPU’s single-thread capability rather than the GPU. The 3dmark single-thread score of 917 and 2-thread score of 1793 indicate that the CPU can handle high IPC workloads, but the scaling from 2 to 4 threads (3363) and 8 threads (4811) shows diminishing returns. This suggests that Rust’s core usage is limited, and the Ryzen 5 5600X’s 32 MB of L3 cache helps reduce memory latency, which is critical for the game’s complex entity interactions.

The CPU’s percentile ranking of 78 places it above average, and its nearest rival, the Intel Core i7-10700, is only 0.3% behind in average score. This parity indicates that the Ryzen 5 5600X is well-matched to the RTX 3080 Ti for this game, as its single-core strength prevents it from becoming a bottleneck at higher resolutions. However, the data shows that at 4K, the CPU’s role diminishes, as the GPU’s limitations dominate the performance profile, with frame rates dropping below 60 FPS even on Medium settings.
