Rust

The Intel Core i5-11400F paired with the AMD Radeon RX 6700 XT delivers a solid, if not spectacular, experience in Rust. The data shows a system that is clearly capable of high refresh rate gaming at 1080p, but one that begins to struggle as resolution and visual fidelity increase. The Core i5-11400F, with its 6 cores and 12 threads, holds its own, but the RX 6700 XT’s performance ceiling is the primary factor in determining playable settings, especially at higher resolutions.

Resolution Scaling

The measured FPS data reveals a predictable and steep performance curve as resolution scales from 1920x1080 up to 3840x2160. At 1080p with Low settings, the combo achieves an average of 166.4 FPS, which is exceptionally high and indicates that the system is not heavily bottlenecked by the CPU in this scenario. However, the drop from 1080p Low to 1440p Low is significant, falling by roughly 47 FPS to 113.4 average. Moving to 4K Low, the average further drops to 65.1 FPS, demonstrating that the GPU is taking on a much heavier load as pixel count quadruples.

The scaling pattern becomes even more pronounced when looking at higher quality presets. At High settings, the average FPS falls from 95.3 at 1080p to 62.8 at 1440p, a 34% reduction. The jump to 4K High is even more brutal, with the average FPS plummeting to 38.3. This steep decline indicates that at 4K, the RX 6700 XT is the limiting component, as it simply cannot maintain the frame rates seen at lower resolutions. The trend suggests that for smooth 4K gameplay, users would need to significantly lower graphical settings, as even Medium settings only yield a 45.8 FPS average at that resolution. The data clearly shows that this combo is best suited for 1080p and, with some compromises, 1440p gaming.

FAQ

Q: What is the best resolution for this combo to achieve high frame rates?

A: The data strongly favors 1920x1080. At Low settings, the system averages 166.4 FPS, and even at High settings it maintains a 95.3 FPS average. This is the only resolution where the system consistently exceeds 60 FPS across all tested presets.

Q: Can this system handle 4K gaming in Rust?

A: It can run the game, but not at high frame rates. At 4K, the average FPS ranges from 65.1 on Low settings down to 28.5 on Ultra. For a playable experience above 60 FPS, you would be restricted to the Low preset at this resolution.

Q: How much of a performance hit is there between 1080p and 1440p?

A: The performance cost is substantial. For example, at High settings, the average FPS drops from 95.3 at 1080p to 62.8 at 1440p, a decrease of over 32 FPS. This indicates a significant GPU load increase.

Q: Is the CPU or GPU the primary bottleneck at 4K?

A: The benchmark results indicate the GPU is the limiting factor at 4K. The massive FPS drops when moving from 1440p to 4K, such as going from 113.4 to 65.1 FPS on Low settings, show that the RX 6700 XT is overwhelmed by the pixel count, leaving the CPU with less relative impact.

Q: What is the performance difference between Low and Ultra settings at 1440p?

A: The gap is very large. At 1440p, the Low preset delivers an average of 113.4 FPS, while the Ultra preset only manages 52.1 FPS. This represents more than a 50% reduction in frame rate, emphasizing the heavy cost of Ultra graphics features.

Q: How does the i5-11400F's multi-threaded performance compare to its rivals?

A: In synthetic benchmarks, the i5-11400F scores an average of 17181. This places it in the 75th percentile of all CPUs. Its nearest rival, the AMD Ryzen 7 5700U, scores 17189, a negligible 0% difference, making them effectively tied in this metric.

GPU Role

The AMD Radeon RX 6700 XT is the workhorse of this pairing, and its 12 GB of GDDR6 memory is a significant asset for Rust. With a 192-bit memory bus providing 384.0 GB/s of bandwidth, the card has ample headroom for the game's large textures and open-world assets, even at 1440p. The GPU’s clock speeds are also notable, with a base clock of 2321 MHz and a boost clock of 2581 MHz. These high frequencies contribute to its strong compute performance, rated at 13.21 TFLOPS.

However, the data shows that this GPU's capabilities are strained at 4K. The measured FPS at 4K Ultra is just 28.5, which is below the threshold for smooth gameplay. The GPU's performance percentile, at 77, shows it is a strong card, but its 12 GB frame buffer and bandwidth are not enough to maintain high frame rates at the highest resolution. The card is clearly more comfortable at 1080p and 1440p, where its pixel rate of 165.2 GPixel/s and texture rate of 413.0 GTexel/s can be fully utilized. In this context, the RX 6700 XT is the star at 1080p, but it becomes the anchor at 4K.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend heavily on the user's display and performance targets. For 1080p gaming, the system is a powerhouse. The High preset offers an excellent balance, with an average of 95.3 FPS, which is more than enough for a smooth experience on high refresh rate monitors. If a player prioritizes maximum frame rates, the Low preset at 1080p delivers an outstanding 166.4 FPS, which is ideal for competitive play.

For 1440p, the Medium preset is the recommended starting point, as it yields a solid 73.5 FPS average. The High preset is also viable at 62.8 FPS, but this is very close to the 60 FPS threshold, and frame drops could become noticeable in busy scenes. The Ultra preset at 1440p is not recommended, as the 52.1 FPS average dips below the desired smoothness for most players. At 4K, the situation is more challenging. Only the Low preset provides a playable average of 65.1 FPS. The Medium preset at 45.8 FPS is borderline, and the High and Ultra presets should be avoided for any serious gameplay. The data suggests that for the best overall experience, users should target 1080p High or 1440p Medium.

How This Combo Ranks

In the grand database of tested combinations for Rust, this particular pairing of Intel Core i5-11400F and AMD Radeon RX 6700 XT ranks 938 out of 1717 combos. This places it in the 55th percentile of all tested systems, indicating that it is a mid-pack performer. This ranking is consistent with the hardware's specifications; the CPU is a capable mid-range part, and the GPU, while strong, is not at the top of the stack.

This rank suggests that while this combo is far from the fastest, it is also not a weak performer. Many other combinations with more powerful CPUs or GPUs will achieve higher frame rates, but this pairing offers a balanced experience that is likely sufficient for the majority of players. The ranking is a reflection of its overall capability across all settings and resolutions, and its mid-pack position underscores the fact that it is a versatile, but not extreme, gaming machine. For players targeting 1080p, this combo would likely rank much higher in a resolution-specific comparison.
