Rust

The Intel Core i5-11400F paired with the AMD Radeon RX 6600 delivers a playable Rust experience primarily at 1080p, where the Low preset achieves a decisive performance lead over other settings. At higher resolutions, the combination struggles to maintain smooth frame rates, making 1440p and 4K viable only with significant graphical compromises. The data shows a clear hierarchy: this combo is best suited for 1080p gaming, with the Low preset providing the highest headroom for competitive play, while Medium offers a balanced visual upgrade at a still-respectable frame rate.

Settings Recommendations

The benchmark results indicate that the Low preset at 1920x1080 is the optimal choice for this hardware configuration, delivering an average of 124.2 FPS. This score is substantially higher than the Medium preset’s 83.7 FPS, representing a 48.4% performance advantage. For players prioritizing smoothness and responsiveness in Rust’s survival gameplay, where sudden combat or environmental events can tax the system, this setting provides the most comfortable margin.

However, the Medium preset at 1080p remains a strong alternative for those seeking better visual fidelity without abandoning playability. At 83.7 FPS, it clears the 60 FPS threshold by a comfortable margin and is 18.3% faster than the High preset’s 69.9 FPS. The Ultra preset at 1080p falls to 52.6 FPS, which dips below the ideal range for fast-paced action, making it less recommended unless visual quality is the absolute priority.

At 2560x1440, the situation changes dramatically. The Low preset is the only setting that maintains a high frame rate, hitting 86.9 FPS. Medium drops to 58.1 FPS, which is borderline, while High (46.8 FPS) and Ultra (38.3 FPS) become increasingly difficult to recommend for consistent play. For 4K, no setting reaches 60 FPS; the Low preset’s 52.4 FPS is the only remotely playable option, with Medium at 35.9 FPS, High at 27.8 FPS, and Ultra at 24.9 FPS being more suitable for screenshots than gameplay. The verdict is clear: stick to 1080p with Medium or Low for the best experience, and reserve higher resolutions for less demanding scenarios.

GPU Role

The AMD Radeon RX 6600 features 8 GB of GDDR6 memory on a 128-bit bus, providing 224.0 GB/s of bandwidth. The GPU’s boost clock reaches 2491 MHz, with a game clock of 2044 MHz and a base clock of 1626 MHz. This memory configuration and clock speed profile directly influence the measured results, particularly at higher resolutions where bandwidth becomes a limiting factor.

The data shows that the GPU is the primary bottleneck when moving from 1080p to 1440p and 4K. At 1080p Low, the combo achieves 124.2 FPS, but at 1440p Low, this falls to 86.9 FPS, a 30% reduction. At 4K Low, the frame rate plummets to 52.4 FPS, which is less than half the 1080p score. This scaling pattern indicates that the RX 6600’s 8 GB frame buffer and 128-bit memory interface struggle to feed the rendering pipeline at higher pixel counts, especially with more demanding presets.

The GPU’s raw compute capabilities, rated at 8.928 TFLOPS FP32, are adequate for 1080p gaming but quickly become overwhelmed at 4K. The benchmark scores reinforce this: the RX 6600 sits at the 69th percentile among all GPUs, with an average benchmark score of 25235. Its nearest rival, the AMD Radeon 890M, scores nearly identically (25246, a 0% delta), while the NVIDIA GeForce RTX 3060 Ti is only 0.5% faster in aggregate benchmarks. This suggests the RX 6600 is a mid-range performer, and Rust’s demanding rendering at high resolutions exposes its limitations.

CPU Role

The Intel Core i5-11400F provides 6 cores and 12 threads, with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. It features 12 MB of shared L3 cache and a 65 W TDP. This processor is a solid mid-range option, placing at the 75th percentile among all CPUs with an average benchmark score of 17181. Its nearest rivals include the AMD Ryzen 7 5700U (score 17189, 0% delta) and the Intel Core i7-1260P (score 17212, -0.2% delta), indicating it competes well with modern laptop-class chips.

In Rust, the CPU’s role is most evident at 1080p with lower graphics settings, where the GPU is not the primary constraint. At 1080p Low, the combo hits 124.2 FPS, suggesting the 11400F’s single-thread performance (3dmark_single_thread score of 868) is sufficient to keep up with the GPU. The multi-threaded capabilities (cinebench_r23_multicore score of 14372) also help with Rust’s world simulation and entity updates, which can be CPU-intensive.

However, the CPU is not the limiting factor at higher resolutions. The frame rate drops from 1080p to 1440p and 4K are nearly identical across all presets, indicating that the GPU is the bottleneck once pixel count increases. For example, at High settings, the drop from 1080p (69.9 FPS) to 1440p (46.8 FPS) is a 33% reduction, and to 4K (27.8 FPS) is a 60% reduction. This pattern holds across all presets, confirming that the 11400F provides ample headroom and is not holding back the RX 6600 in this game.

How This Combo Ranks

The combination of the Intel Core i5-11400F and AMD Radeon RX 6600 ranks 1397 out of 1717 tested combos in Rust, placing it in the bottom 19% of all configurations. This low rank is somewhat surprising given the individual components’ mid-range status, but it reflects Rust’s demanding nature and the specific optimization of this pairing.

The rank suggests that while this combo is capable of 1080p gaming, it is far from top-tier. Many other combinations deliver higher frame rates, particularly those with more powerful GPUs or CPUs with higher single-thread performance. The data indicates that the RX 6600’s 69th percentile GPU score and the 11400F’s 75th percentile CPU score do not translate into a high combo rank, implying that Rust’s engine is sensitive to specific hardware characteristics that this pairing lacks.

For context, the combo’s performance at 1080p Low (124.2 FPS) is respectable, but at 4K Ultra (24.9 FPS), it falls well below playable thresholds. This wide variance across resolutions and settings underscores why the combo ranks so low overall—it cannot deliver a consistent high-end experience. Players with this hardware should temper expectations and focus on 1080p gaming, where the rank is less relevant than the actual playability.

Measured FPS Breakdown

At 1920x1080, the measured average FPS across presets is: Low at 124.2, Medium at 83.7, High at 69.9, and Ultra at 52.6. The progression from Low to Ultra shows a steady decline, with Ultra being 57.6% slower than Low. This resolution is clearly the sweet spot for this combo, with all presets except Ultra remaining above 60 FPS.

At 2560x1440, the scores are: Low at 86.9, Medium at 58.1, High at 46.8, and Ultra at 38.3. The jump from 1080p to 1440p costs roughly 30% performance on the Low preset (from 124.2 to 86.9 FPS), and the Medium preset falls below 60 FPS, making it a marginal choice. High and Ultra are not recommended for competitive play.

At 3840x2160, the results are: Low at 52.4, Medium at 35.9, High at 27.8, and Ultra at 24.9. None of these scores reach 60 FPS, and even the Low preset is only marginally playable. The Ultra preset’s 24.9 FPS is less than half of the 1080p Low score, highlighting the GPU’s severe limitations at 4K.

The data also shows that the gap between Low and Ultra widens at higher resolutions. At 1080p, the difference is 71.6 FPS (124.2 vs 52.6), but at 4K, it narrows to 27.5 FPS (52.4 vs 24.9). This suggests that at 4K, the GPU is so constrained that preset choice has less impact on absolute frame rates.

Resolution Scaling

The scaling from 1080p to 1440p and 4K reveals a consistent pattern across all presets, with frame rates dropping dramatically as pixel count increases. For the Low preset, the drop from 1080p (124.2 FPS) to 1440p (86.9 FPS) is a 30% reduction, and to 4K (52.4 FPS) is a 57.8% reduction. This indicates that the RX 6600 is heavily pixel-bound, with its 224.0 GB/s memory bandwidth and 128-bit bus struggling to feed the rendering pipeline at higher resolutions.

The Medium preset shows a similar trend: 83.7 FPS at 1080p, 58.1 FPS at 1440p (a 30.6% drop), and 35.9 FPS at 4K (a 57.1% drop). High settings follow suit, with 69.9 FPS dropping to 46.8 FPS at 1440p (33% drop) and 27.8 FPS at 4K (60.2% drop). Ultra is the most affected, falling from 52.6 FPS at 1080p to 38.3 FPS at 1440p (27.2% drop) and 24.9 FPS at 4K (52.7% drop).

The consistency of these drops—roughly 30% from 1080p to 1440p and 55-60% from 1080p to 4K—strongly suggests that the GPU is the limiting component. If the CPU were the bottleneck, we would expect smaller frame rate differences at higher resolutions, as the CPU load would not increase proportionally with pixel count. Instead, the GPU’s rendering load scales directly with resolution, and the RX 6600’s compute and memory resources are insufficient for 4K gaming in Rust. This analysis confirms that players should target 1080p for the best experience, with 1440p Low as a secondary option for those with higher-resolution monitors.
