Rust

The Intel Core i5-11400F paired with the Intel Arc B580 presents a mid-range combination that is tested against Rust, a survival title known for its demanding simulation and rendering loads. The data shows a system that is highly capable at standard resolutions but runs into a hard ceiling at 4K, where even the lowest settings fail to maintain the 60 FPS playability threshold. This analysis breaks down the recorded measurements to show exactly where this combo excels and where it falls short.

FAQ

Q: What is the best playable setting at 1920x1080 for this combo?

A: The High preset is the most demanding setting that stays above 60 FPS, delivering an average of 76.9 FPS. The Low and Medium presets also clear the threshold, with 134.7 FPS and 92 FPS respectively, but High offers the best visual quality while remaining fluid.

Q: Can this system run Rust at 2560x1440?

A: Yes, but with limitations. The Medium preset is the most demanding playable option, hitting exactly 61 FPS on average. The Low preset runs much faster at 90.7 FPS, but the High preset drops to 51.4 FPS, and Ultra falls to 38.4 FPS, both below the 60 FPS threshold.

Q: Is 4K resolution viable for this game with these components?

A: No. At 3840x2160, the best recorded average is 56.4 FPS on the Low preset, which is below the 60 FPS playable threshold. The Medium preset drops to 38 FPS, High to 30.1 FPS, and Ultra to 20.8 FPS, making 4K unplayable according to the data.

Q: How does the Arc B580 compare to its nearest GPU rivals in raw benchmark scores?

A: The Arc B580 has an average benchmark score of 23021. It sits within a tight cluster: the NVIDIA GeForce RTX 2080 is 0.6% behind, the AMD Radeon RX 580 2048SP is 0.2% behind, and the NVIDIA GeForce RTX 3080 is 0.7% ahead. The NVIDIA P106-100 leads by 1.0%.

Q: How does the Core i5-11400F compare to its nearest CPU rivals?

A: The i5-11400F averages 17177 in benchmarks. It is effectively tied with the AMD EPYC 7H12, which is 0.3% behind, and the Intel Core Ultra 7 164U, which is 0.6% behind. The Intel Core i5-12450H is 0.4% ahead, and the AMD Ryzen 3 PRO 8300G is 0.6% ahead.

Q: What is the overall rank of this CPU and GPU combo for Rust?

A: The combination ranks 2805 out of 3723 tested combos in the database. This places it in the lower-middle portion of the ranking, indicating that while it can handle the game at certain settings, many other configurations deliver higher performance.

Best Settings per Resolution

The data indicates a clear progression of playable settings based on resolution. At 1920x1080, the system has headroom. The High preset is the most demanding that maintains 60 FPS, recording an average of 76.9 FPS. This is the recommended setting for full HD, as it balances visual fidelity with a comfortable margin above the playability threshold.

Moving to 2560x1440, the situation tightens. The Medium preset becomes the optimal choice, as it is the most demanding setting that stays at or above 60 FPS, with an average of exactly 61 FPS. This is a razor-thin margin, so users should expect occasional dips below 60 FPS in busy scenes. The Low preset offers a safer experience at 90.7 FPS, but for those prioritizing visual quality, Medium is the boundary.

At 3840x2160, there is no playable preset. The best recorded average is 56.4 FPS on Low, which falls short of the 60 FPS threshold. This means that for 4K gaming, this combo cannot deliver a smooth experience in Rust, and users must either lower the resolution or accept sub-60 FPS performance.

Similar Performance Alternatives

The database lists nearby rivals for both components, which helps contextualize what other hardware would behave similarly in this game. For the CPU, the Intel Core i5-11400F is bracketed by several processors with nearly identical average scores. The AMD EPYC 7H12 scores 17120, just 0.3% lower, meaning it would likely produce very similar frame rates in Rust. The Intel Core Ultra 7 164U scores 17074, 0.6% lower, and the Intel Core i5-12450H scores 17239, 0.4% higher. The AMD Ryzen 3 PRO 8300G scores 17278, 0.6% higher. All of these would behave almost indistinguishably from the i5-11400F in terms of CPU-bound performance.

On the GPU side, the Intel Arc B580 has an average score of 23021, and its nearest rivals show how close the field is. The NVIDIA GeForce RTX 2080 scores 22895, 0.6% lower, so it would deliver nearly identical frame rates. The AMD Radeon RX 580 2048SP scores 23061, 0.2% higher, and the NVIDIA GeForce RTX 3080 scores 23172, 0.7% higher. The NVIDIA P106-100 scores 23249, 1.0% higher. In practice, swapping the Arc B580 for any of these cards would result in very similar measured FPS in Rust, with differences well within a few percent.

The Verdict

The verdict is clear from the recorded data: this PC can run Rust, but the experience is heavily dependent on resolution. At 1920x1080, the system performs well. The High preset delivers 76.9 FPS, which clears the 60 FPS threshold with a solid margin. The Low and Medium presets are also playable, making 1080p a fully viable resolution for this combo.

At 2560x1440, the system is playable but limited. The Medium preset hits 61 FPS, just barely clearing the threshold. The Low preset runs at 90.7 FPS, offering a more stable experience, while High and Ultra fall to 51.4 FPS and 38.4 FPS, respectively. For 1440p, users must choose between visual quality and smoothness, with Medium being the absolute ceiling.

At 3840x2160, the verdict is negative. No settings achieve 60 FPS. The Low preset peaks at 56.4 FPS, which is below the playable threshold, and higher presets drop dramatically. This combo is not suitable for 4K gaming in Rust, and users should avoid that resolution entirely.

CPU and GPU Roles

The data reveals how the balance between CPU and GPU shifts across resolutions. At 1920x1080, the system shows significant scaling with settings. The Low preset hits 134.7 FPS, which drops to 92 FPS at Medium, then 76.9 FPS at High, and finally 55 FPS at Ultra. This steep drop from Low to Ultra suggests that the GPU becomes the limiting factor as graphical load increases, but the CPU is strong enough to feed the Arc B580 at lower settings.

At 2560x1440, the same pattern holds but with lower absolute numbers. Low runs at 90.7 FPS, Medium at 61 FPS, High at 51.4 FPS, and Ultra at 38.4 FPS. The scaling from Medium to High is a drop of about 16%, which is less severe than the 1080p drop from Medium to High (about 16.5% as well). This indicates that the GPU is increasingly stressed as resolution rises, while the CPU still provides enough throughput.

At 3840x2160, the GPU is clearly the dominant bottleneck. Low runs at 56.4 FPS, Medium at 38 FPS, High at 30.1 FPS, and Ultra at 20.8 FPS. The massive reductions with each preset step, especially from Low to Medium (a 32.6% drop), show that the Arc B580 is overwhelmed at 4K. The CPU, with its 6 cores and 12 threads, is likely not the limiting factor at this resolution; the GPU's rendering capabilities are what hold the system back.

How This Combo Ranks

In the database of tested combinations, this specific pairing of the Intel Core i5-11400F and Intel Arc B580 ranks 2805 out of 3723 combos for Rust. This places it in the 75th percentile of all tested systems, meaning roughly 75% of other combinations perform better. This is a modest ranking, reflecting that while the combo is capable at 1080p and entry-level 1440p, it lacks the power for high-refresh or high-resolution play.

The rank is consistent with the measured FPS data. The combo does not reach the top tiers of performance, but it is far from the bottom. It sits in a range where users can enjoy the game at standard settings, but enthusiasts looking for maxed-out visuals at high frame rates would need to look at more powerful hardware.

| 1920x1080 | Medium | 92.0 |

| 1920x1080 | Ultra | 55.0 |

The data shows a clear hierarchy. At 1080p, the system has a wide range of usable settings, with Low providing a high refresh rate experience and High still maintaining a solid 76.9 FPS. At 1440p, the playable range narrows to Low and Medium, with Medium being the boundary at exactly 61 FPS. At 4K, no preset is playable, and the best option, Low, falls short of the 60 FPS target by 3.6 FPS. The min and max FPS values were not recorded, so the analysis relies solely on average FPS, but the averages are consistent across resolutions and settings, painting a complete picture of this combo's capabilities.
