Rust

The AMD Ryzen 5 7400F paired with the NVIDIA GeForce RTX 3080 Ti delivers a compelling, though not flawless, 1080p and 1440p experience in Rust, with 4K remaining a challenge at the highest presets. The data shows a system that is heavily GPU-bound at lower resolutions, but which begins to show CPU limitations when settings are dropped. This combination ranks in the 78th percentile for this game, placing it ahead of a significant majority of tested hardware configurations.

Resolution Scaling

The measured FPS data reveals a clear and predictable trend: performance degrades as resolution increases, but the rate of that degradation is highly dependent on the graphics settings. At 1080p with Low settings, the combo produces an average of 216 FPS. Moving to 1440p Low drops this to 154 FPS, a 29% reduction. Pushing to 4K Low yields 91 FPS, which is a 58% drop from the 1080p figure. This scaling pattern is characteristic of a system where the CPU has ample headroom at lower resolutions, allowing the GPU to work harder as pixel count increases.

The story changes when we look at higher settings. At the Ultra preset, the average FPS at 1080p is 96. At 1440p Ultra, it falls to 66 FPS, a 31% decrease. At 4K Ultra, the average plummets to 39 FPS, a 59% drop from 1080p. The percentage drop from 1080p to 4K is remarkably similar across Low (58%) and Ultra (59%), which suggests that the scaling factor is primarily tied to the GPU's rendering load. However, the absolute numbers tell a different story about the bottleneck. At 1080p Low, the system is clearly CPU-limited, as the GPU is not being fully utilized. This is evidenced by the fact that dropping from 1080p Low (216 FPS) to 1440p Low (154 FPS) only reduces performance by 29%, while the pixel count increases by 78%. The GPU has enough headroom to handle the extra pixels without a proportional drop in frame rate.

As resolution increases to 4K, the GPU becomes the primary limiting factor. The 4K Low result of 91 FPS is a massive drop from the 1440p result, indicating that the RTX 3080 Ti's rendering capabilities are being saturated. The gap between settings narrows at 4K, with the difference between Low (91 FPS) and High (52 FPS) being just 39 FPS. This compression of the FPS range at higher resolutions is a classic sign of a GPU bottleneck, where the graphics card's fillrate and shading power are the limiting constraints. The data implies that users targeting 4K will need to make significant compromises on visual quality to achieve playable frame rates.

The 1440p results offer the most balanced picture. The jump from 1080p High (127 FPS) to 1440p High (87 FPS) is a 31% drop, while the jump from 1080p Medium (150 FPS) to 1440p Medium (103 FPS) is a 31% drop as well. This consistency indicates that the system is scaling as expected, with neither component being an overwhelming bottleneck at this resolution. The Medium preset at 1440p, with an average of 103 FPS, appears to be the sweet spot for this hardware, providing a high frame rate while still pushing a significant number of pixels.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in this pairing, and its influence on Rust's performance is most apparent at higher resolutions and settings. The GPU features 12 GB of GDDR6X memory on a 384-bit bus, yielding a bandwidth of 912.4 GB/s. This substantial memory subsystem is critical for a game like Rust, which can be demanding on texture loading and large world data. The data suggests this bandwidth is sufficient, as the GPU is able to maintain playable frame rates at 1440p across all settings.

The GPU's clock speeds are listed with a base of 1365 MHz and a boost of 1665 MHz. The benchmark results in Rust indicate that the card is able to sustain high performance, but the actual clock behavior is not detailed in the FPS data. We can infer from the resolution scaling that the GPU is the limiting factor at 4K. The drop from 1440p Medium (103 FPS) to 4K Medium (61 FPS) is a 41% reduction, which is a significant hit. This suggests that the card's raw compute power, rated at 34.10 TFLOPS FP32, is being taxed by the 4K workload.

The GPU's percentile rank of 83 among all GPUs and its average benchmark score of 41187 place it in the upper echelon of graphics cards. Its nearest rivals in synthetic benchmarks include the NVIDIA Tesla M40 24 GB (avg score 41707, deltaPct -1.2) and the NVIDIA GeForce RTX 5070 (avg score 40377, deltaPct 2). While these synthetic scores are close, Rust's real-world performance shows the RTX 3080 Ti's strength. The 12 GB of VRAM is a crucial asset, as it likely prevents texture thrashing at high settings in Rust's expansive environments. The data shows that at 1080p, the GPU is not the bottleneck, as the CPU is limiting performance. However, at 4K Ultra, the GPU's limits are clearly exposed, with an average of just 39 FPS.

Interpreting this rank requires context. The 2953 combos tested likely include a wide range of hardware, from entry-level integrated graphics to the most powerful HEDT and dual-GPU configurations. Being in the top 22% means this system outperforms the vast majority of setups. The data shows that the RTX 3080 Ti's 83rd percentile ranking among all GPUs and the CPU's 83rd percentile ranking among all CPUs are both strong, and their combination in this game produces a result that is in line with those individual strengths. The rank implies that this is a balanced pairing for Rust, where neither component is severely holding back the other in a way that would push the combo lower in the rankings.

The rank also suggests that the system is well-suited for high-refresh-rate gaming at 1080p and 1440p. The measured FPS at 1080p Medium (150 FPS) and 1440p Medium (103 FPS) are well above the 60 FPS threshold and are capable of driving 144Hz monitors. The 4K performance, while lower, is still playable at Medium settings with an average of 61 FPS. The ranking is a reflection of this versatility, confirming that the hardware can handle a variety of resolutions and settings with acceptable performance, even if it doesn't dominate at the highest end.

CPU Role

The AMD Ryzen 5 7400F is a 6-core, 12-thread processor based on the Zen 4 architecture, codenamed Raphael. It has a base clock of 3.70 GHz and a boost clock of 4.70 GHz. The CPU's synthetic benchmark scores are strong, with a Cinebench R23 multi-core score of 21765 and a single-core score of 3072. These figures indicate a capable processor for gaming. In Rust, the CPU's role is most evident at lower resolutions and settings, where it becomes the primary bottleneck.

The evidence for this is in the FPS data. At 1080p Low, the system achieves 216 FPS. This is a high frame rate, but the fact that it doesn't scale proportionally with the GPU's capabilities suggests the CPU is reaching its limit. The Ryzen 5 7400F's 32 MB of shared L3 cache is likely a factor here. Rust is known for its complex simulations and physics, which can be cache-sensitive. The CPU's performance in the Passmark Physics test, with a score of 1660, provides a hint at its gaming capabilities.

The CPU's nearest rivals, according to synthetic benchmarks, are the Intel Core i5-14600T (deltaPct 0.1) and the AMD Ryzen AI 7 PRO 360 (deltaPct 0.3). This indicates that the Ryzen 5 7400F is positioned in a highly competitive performance tier. In Rust, the CPU's 6 cores and 12 threads appear sufficient to feed the RTX 3080 Ti at 1080p and 1440p, as the frame rates are high. However, the fact that the 1080p Low (216 FPS) and 1080p Medium (150 FPS) results are so high suggests the CPU is not a major limiting factor until the user wants to push frame rates beyond 150 FPS. At that point, the CPU's single-thread performance and cache latency become more critical.

Measured FPS Breakdown

The following table details the average FPS for each resolution and settings preset combination:

• 1920x1080 (1080p)
• Low: 216 FPS
• Medium: 150 FPS (min 128, max 173)
• High: 127 FPS
• Ultra: 96 FPS

• 2560x1440 (1440p)
• Low: 154 FPS
• Medium: 103 FPS (min 88, max 119)
• High: 87 FPS
• Ultra: 66 FPS

• 3840x2160 (4K)
• Low: 91 FPS
• Medium: 61 FPS (min 52, max 70)
• High: 52 FPS
• Ultra: 39 FPS

The data shows a consistent hierarchy across all resolutions: Low is fastest, followed by Medium, then High, with Ultra being the slowest. The gap between Low and Ultra is substantial. At 1080p, the difference between them is 120 FPS. At 1440p, it's 88 FPS. At 4K, it's 52 FPS. This indicates that the Ultra preset is extremely demanding, likely due to high levels of draw distance, texture quality, and post-processing effects.

The Medium preset data is the only one that includes min and max FPS figures. At 1080p Medium, the frametime variance is 45 FPS (from 128 to 173). At 1440p Medium, the variance is 31 FPS (from 88 to 119). At 4K Medium, the variance is 18 FPS (from 52 to 70). This shows that as resolution increases, the frametime consistency improves, which is a counterintuitive but logical result of the system becoming more GPU-bound. The GPU is better able to maintain a consistent output when it is the limiting factor, whereas the CPU can cause more erratic frame times when it is struggling to keep up.

Settings Recommendations

Based on the measured data, the optimal settings preset depends heavily on the user's target resolution and desired frame rate.

For 1080p gaming, the Medium preset offers the best combination of high frame rate and visual fidelity. At 150 FPS average, it provides a smooth experience on high-refresh-rate monitors. The Low preset (216 FPS) is only recommended for competitive play where maximum frame rate is paramount, as the visual quality will be significantly lower. The High preset (127 FPS) is also viable, but the jump from Medium to High only yields a 23 FPS loss, which may not justify the visual difference for some. The Ultra preset (96 FPS) is playable but introduces a significant performance penalty.

For 1440p gaming, the Medium preset is again the standout choice. With an average of 103 FPS, it is the only preset that comfortably exceeds the 100 FPS threshold. The High preset (87 FPS) is a solid alternative for those with 60Hz monitors or those who prioritize visual quality over raw frame rate. The Low preset (154 FPS) is available for competitive play, while Ultra (66 FPS) is the most demanding and will be best for single-player or less action-heavy scenarios.

For 4K gaming, the data suggests that users must make significant compromises. The Medium preset (61 FPS) is the only one that provides a near-60 FPS average. The Low preset (91 FPS) is a viable option for maintaining high frame rates, but the visual quality will be poor. The High preset (52 FPS) and Ultra preset (39 FPS) are below the 60 FPS target and will result in a less smooth experience. Therefore, for 4K, Medium is the recommended starting point, with Low as an option for those who prioritize frame rate above all else. The data clearly shows that the Ultra preset is not a practical choice for this hardware at 4K.
