Rust

The Intel Core i5-11400F paired with the AMD Radeon RX 9070 presents a strong 1080p and 1440p gaming configuration for Rust, but the data indicates that 4K Ultra settings are beyond its comfortable reach. Benchmark results show the combo ranks in the 68th percentile of tested configurations for this title, positioning it as a capable mid-to-high-tier performer that scales predictably with resolution and settings.

Resolution Scaling

The measured FPS data reveals a clear pattern of performance degradation as resolution increases, with the GPU becoming the dominant limiting factor at 4K. At 1080p with High settings, the combo delivers 120 FPS average, which drops to 83 FPS at 1440p and further to 49 FPS at 4K — a reduction of approximately 31% from 1080p to 1440p and 59% from 1080p to 4K. This steep decline at higher resolutions is characteristic of a system where the graphics card is being pushed to its limits, especially given the RX 9070's 16 GB GDDR6 memory and 644.6 GB/s bandwidth.

The scaling behavior differs notably across settings presets. When using Low settings, the frame rate drops from 175 FPS at 1080p to 146 FPS at 1440p (a 17% decrease) and then to 86 FPS at 4K (a 51% decrease from 1080p). The Low preset's 4K performance of 86 FPS remains playable, suggesting that the GPU still has headroom when graphical load is reduced. In contrast, the Ultra preset shows the most dramatic scaling: 91 FPS at 1080p falls to 63 FPS at 1440p and then plummets to 37 FPS at 4K. This 59% drop from 1080p to 4K on Ultra indicates that the RX 9070's compute resources — 3584 shading units and 36.13 TFLOPS FP32 — are saturated by the combination of high resolution and maximum graphical fidelity.

The Medium preset provides the most complete data with min/max FPS values, showing a 142 FPS average at 1080p with a range of 121-164 FPS, 98 FPS at 1440p with a range of 83-113 FPS, and 58 FPS at 4K with a range of 49-67 FPS. The consistent spacing between resolution tiers at Medium settings — roughly 44 FPS drops between each step — suggests balanced scaling where neither the CPU nor GPU creates a disproportionate bottleneck. However, the fact that 4K Medium (58 FPS) falls below the 60 FPS threshold while 1440p Medium (98 FPS) remains comfortable indicates that 4K is the resolution where this combo begins to struggle.

FAQ

Q: Can this combo handle Rust at 4K resolution?

A: At 4K, the combo delivers 86 FPS on Low, 58 FPS on Medium, 49 FPS on High, and 37 FPS on Ultra settings. Only the Low preset achieves a consistently smooth experience above 60 FPS; Medium produces playable but not ideal frame rates, while High and Ultra fall below the 50 FPS mark.

A: At 1080p, Low settings produce 175 FPS average, while Ultra produces 91 FPS average — a 48% reduction in frame rate. The Medium preset at 142 FPS and High at 120 FPS sit between these extremes, showing that each step up in quality costs roughly 25-30 FPS at this resolution.

Q: How does this combo rank among all tested configurations for Rust?

A: The combo ranks 1190th out of 3723 tested combinations, placing it in the top 32% of all configurations. This ranking reflects its strong mid-to-high-tier performance, though it is not among the elite setups that achieve the highest frame rates at maximum settings across all resolutions.

Settings Recommendations

For players prioritizing smooth competitive gameplay, the Low preset at 1440p delivers 146 FPS, which is the highest frame rate achievable at that resolution and only 29 FPS short of the 1080p Low result. This makes 1440p Low the optimal choice for high-refresh-rate monitors, as it provides the responsiveness needed for Rust's survival combat while maintaining visual clarity through the higher resolution.

The Medium preset at 1440p offers the best balance for most players, delivering 98 FPS average with a range of 83-113 FPS. This configuration provides a 33% improvement over 1080p Ultra's 91 FPS while still maintaining frame rates above 80 FPS even at the minimum. The visual fidelity gains from Medium settings in Rust — including better texture filtering and shadow quality — justify the 48 FPS sacrifice from Low settings.

For players with 4K displays, the Low preset at 86 FPS is the only recommended option, as it remains above the 60 FPS threshold. The Medium preset at 58 FPS is borderline playable but risks dropping to 49 FPS in demanding scenes, which could impact gameplay. The High and Ultra presets at 4K produce 49 FPS and 37 FPS respectively, making them unsuitable for anything other than static screenshots.

At 1080p, the High preset provides the best experience for players with standard 60 Hz monitors, delivering 120 FPS with ample headroom above the refresh rate. The Ultra preset's 91 FPS is still smooth but offers diminishing returns over High for the 29 FPS cost. Players with 144 Hz panels should consider the Medium preset at 142 FPS, which stays above the refresh rate threshold while providing better visuals than Low.

Measured FPS Breakdown

The complete measured FPS dataset for this combo spans three resolutions and four settings tiers. At 1920x1080, Low settings produce the highest average at 175 FPS, followed by Medium at 142 FPS (range 121-164), High at 120 FPS, and Ultra at 91 FPS. The 84 FPS spread between Low and Ultra at 1080p demonstrates the significant impact of graphical settings on performance when resolution is not the primary constraint.

At 2560x1440, the frame rates compress to a tighter band. Low settings average 146 FPS, Medium averages 98 FPS (range 83-113), High averages 83 FPS, and Ultra averages 63 FPS. The 83 FPS difference between Low and Ultra at 1440p is nearly identical to the 1080p spread, but the absolute values are lower across every preset, indicating that the increased pixel count affects all settings proportionally.

At 3840x2160, the performance drops become more pronounced. Low settings average 86 FPS, Medium averages 58 FPS (range 49-67), High averages 49 FPS, and Ultra averages 37 FPS. The 49 FPS difference between Low and Ultra at 4K is significantly smaller than at lower resolutions, revealing that the RX 9070's rendering pipeline becomes saturated regardless of settings when pushing 8.3 million pixels. The 4K Medium range of 49-67 FPS shows considerable variance, suggesting that Rust's dynamic scenes can cause frame rate swings of nearly 20 FPS at this resolution.

Comparing the Medium preset across resolutions provides the clearest picture of scaling: 142 FPS at 1080p → 98 FPS at 1440p → 58 FPS at 4K. This represents a 31% drop from 1080p to 1440p and a 41% drop from 1440p to 4K, with the total loss from 1080p to 4K reaching 59%. The High preset scales similarly: 120 → 83 → 49 FPS, with a 59% total reduction. Low settings scale somewhat better, declining from 175 → 146 → 86 FPS, a 51% total reduction, suggesting that the GPU has more headroom when texture and shader complexity are minimized.

How This Combo Ranks

The combo's rank of 1190 out of 3723 tested configurations places it in the upper third of all systems tested for Rust. This percentile positioning is consistent with the measured frame rates, which show strong 1080p performance capable of exceeding 175 FPS on Low settings, but mid-pack 4K performance that struggles to maintain 60 FPS on anything above Medium settings.

The CPU component's individual standing reinforces this assessment. The Intel Core i5-11400F holds a percentile rank of 71 among all CPUs, with an average benchmark score of 17177. Its nearest rivals include the AMD EPYC 7H12 (0.3% higher score), Intel Core i5-12450H (0.4% lower), and AMD Ryzen 3 PRO 8300G (0.6% lower). These tight margins indicate the i5-11400F sits at a performance plateau where many comparable processors deliver nearly identical results, meaning the CPU is unlikely to be the differentiating factor in Rust performance.

Similarly, the AMD Radeon RX 9070's percentile rank of 69 among all GPUs, with an average benchmark score of 23877, places it in a cluster of closely matched graphics cards. Its nearest rivals — GTX TITAN Z (0.6% higher), RX 6800S (0.8% lower), RTX 3080 Mobile (1.1% higher), and RTX 2080 SUPER (1.2% lower) — all fall within a 2% performance band. This suggests that in Rust specifically, the combo's 1190th rank is driven more by the overall system balance than by any single component being exceptional or deficient.

The gap between the combo's 1080p and 4K performance — from 175 FPS on Low to 37 FPS on Ultra — is substantial but not unusual for a mid-range CPU paired with a high-end GPU. The ranking reflects that while this system can deliver competitive frame rates at mainstream resolutions, it does not reach the top-tier performance levels achieved by combinations with more powerful CPUs and GPUs that can maintain high FPS even at 4K Ultra.

CPU Role

The Intel Core i5-11400F contributes to this combo's performance through its 6 cores and 12 threads, operating at a base clock of 2.60 GHz and boosting up to 4.40 GHz. The CPU's Rocket Lake architecture, built on Intel's 14 nm process, provides a 12 MB shared L3 cache and dual-channel DDR4 memory support with 51.2 GB/s bandwidth. These specifications translate to benchmark scores that indicate solid gaming performance: Cinebench R23 multi-core of 14340 and single-core of 2024, Geekbench multi-core of 7737 and single-core of 1777, and 3DMark 2-thread score of 1691.

In Rust, which typically benefits from strong single-threaded performance due to its simulation and networking requirements, the CPU's 4.40 GHz boost clock and 868 3DMark single-thread score suggest it can adequately feed the RX 9070 at 1080p. Evidence for this lies in the 1080p Low result of 175 FPS, which approaches the practical limits for many games and indicates the CPU is not severely constraining the GPU at this resolution. The 3DMark 16-thread score of 5619 versus the 2-thread score of 1691 shows that multi-threaded scaling is present but modest, with only 3.3x improvement from 2 to 16 threads — a typical profile for a 6-core/12-thread processor.

At higher resolutions, the CPU's role diminishes as the GPU becomes the bottleneck. The fact that 4K Low (86 FPS) is only 49% lower than 1080p Low (175 FPS) while 4K Ultra (37 FPS) is 59% lower than 1080p Ultra (91 FPS) suggests that at 4K, the RX 9070's rendering throughput — 322.6 GPixel/s pixel rate and 564.5 GTexel/s texture rate — determines the frame rate, not the CPU's processing capabilities. The CPU's PassMark multi-thread score of 16908 and single-thread score of 2981 place it well within the range needed to avoid becoming the primary limiting factor in Rust at 1440p and below, where the measured 146 FPS on Low settings demonstrates the system's ability to deliver high frame rates when the GPU has sufficient headroom.
