Rust

The Intel Core i5-13400F paired with the AMD Radeon RX 7900 XT delivers a wide range of performance in Rust, scaling predictably with resolution and preset. The data shows a system that is firmly capable of high-refresh-rate play at 1080p and 1440p, while 4K demands preset compromises to maintain fluidity. This analysis walks through the measured FPS, optimal settings, and the system's position among tested hardware combinations.

Measured FPS Breakdown

At 1920x1080, the combination produces exceptionally high frame rates across all four tested presets. The Low preset yields an average of 214.4 FPS, which is the highest result in the entire measured set. Medium drops to 160.8 FPS average, still far above any practical refresh-rate ceiling. High settings produce 135.0 FPS average, and Ultra, the most demanding preset, still holds an average of 102.6 FPS. The gap between Low and Ultra is 111.8 FPS, indicating that the GPU has substantial headroom even at the highest settings.

Moving to 2560x1440, the frame rates remain strong but show the expected cost of additional pixels. Low averages 165.2 FPS, a 49.2 FPS reduction from the 1080p Low result. Medium averages 115.2 FPS, High averages 96.2 FPS, and Ultra averages 69.5 FPS. The spread between Low and Ultra at this resolution is 95.7 FPS, slightly narrower than at 1080p. The Ultra result of 69.5 FPS is notably close to the 60 FPS playability threshold, but it clears it with margin.

At 3840x2160, the performance curve steepens considerably. Low averages 96.9 FPS, which is still highly playable. Medium averages 69.0 FPS, narrowly above the 60 FPS threshold. High drops to 54.4 FPS average, falling below the threshold, and Ultra averages 40.8 FPS, the lowest result in the dataset. The difference between Low and Ultra at 4K is 56.1 FPS, showing that the 4K Ultra preset demands nearly 2.4 times the GPU resources of 4K Low. The minimum and maximum FPS values are not provided in the data, so the analysis relies solely on average frame rates.

Best Settings per Resolution

At 3840x2160, the most demanding preset that maintains an average of at least 60 FPS is Medium, which achieves 69.0 FPS. High falls to 54.4 FPS, so it cannot be recommended for a 60 FPS target. Ultra at 40.8 FPS is likewise below the threshold. Low at 96.9 FPS is playable but sacrifices visual quality unnecessarily when Medium still clears the bar.

At 2560x1440, the data shows that every preset — Low, Medium, High, and Ultra — averages above 60 FPS. The best playable setting is therefore Ultra, with an average of 69.5 FPS. This is a comfortable margin above the threshold, and the 102.6 FPS at 1080p Ultra suggests that 1440p Ultra is the highest quality setting this combination can drive without dropping below 60 FPS.

At 1920x1080, all four presets exceed 60 FPS, and Ultra is the best playable setting with an average of 102.6 FPS. The 1080p Ultra result is 33.1 FPS higher than the 1440p Ultra result, showing that the resolution increase costs more than one-third of the frame rate at the highest preset. For 1080p displays, the system has enough headroom to run Ultra and still approach 100 FPS.

How This Combo Ranks

The combo ranks 701st out of 3,723 tested combinations for Rust, placing it in the top 18.8% of all tested systems. This percentile position indicates that the i5-13400F and RX 7900 XT together outperform the vast majority of hardware pairings in this game. The ranking reflects the GPU's strong rasterization throughput, which is the dominant factor in Rust's rendering workload.

The CPU alone sits at the 77th percentile against all tested CPUs, with an average benchmark score of 25,292. The GPU holds the 55th percentile against all tested GPUs, with an average benchmark score of 13,745. The combination's rank of 701 out of 3,723 suggests that the CPU's higher percentile ranking helps boost the overall position, though the GPU's raw performance in Rust-specific workloads is what carries the measured FPS results.

Notably, the GPU's percentile rank is lower than the CPU's, but the measured FPS at 1080p and 1440p show no obvious CPU bottleneck. The 214.4 FPS at 1080p Low and 165.2 FPS at 1440p Low are indicative of a system where neither component is severely limiting at lower settings. At 4K, the GPU becomes the clear constraint, as evidenced by the steep drop in frame rates across presets.

Similar Performance Alternatives

The CPU's nearest rivals, based on average benchmark scores, include the AMD Ryzen 9 6900HS, which scores 25,284 with a delta of 0%, and the AMD Ryzen 7 6800H, which scores 25,201 with a delta of 0.4%. These two mobile processors effectively match the i5-13400F's aggregate performance, though they are designed for laptops and may exhibit different sustained behavior. The Intel Core 5 120 scores 25,362 with a delta of -0.3%, and the AMD Ryzen 5 5600X3D scores 25,365 with a delta of -0.3%, both slightly outperforming the i5-13400F by a negligible margin. In Rust, where single-thread performance matters, the 5600X3D's cache advantage could yield different results, but the benchmark data shows near-parity.

The GPU's nearest rivals are more varied. The AMD Radeon 660M scores 13,812 with a delta of -0.5%, the NVIDIA RTX A2000 Mobile scores 13,821 with a delta of -0.5%, and the AMD Radeon RX 570X scores 13,871 with a delta of -0.9%. These are all substantially slower GPUs in real-world gaming, and the average benchmark score parity is misleading because the RX 7900 XT's PassMark G3D score of 29,009 dwarfs the others. The AMD Radeon RX 9070 XT scores 13,543 with a delta of 1.5%, which is a closer competitor in aggregate, but again the G3D score difference suggests the 9070 XT is not a direct equal. Users seeking similar Rust performance should look at GPUs that deliver comparable 4K Medium frame rates, which the data indicates is around 69 FPS.

CPU and GPU Roles

The data reveals a clear shift in component responsibility as resolution changes. At 1920x1080, the CPU has a more prominent role, since the GPU can produce very high frame rates that stress the processor's ability to feed frames. The 214.4 FPS Low result and 102.6 FPS Ultra result at 1080p show that even the most demanding preset leaves the GPU with enough headroom to stay above 100 FPS. The CPU's 10 cores and 16 threads, with a boost clock of 4.60 GHz, are sufficient to handle Rust's simulation and rendering logic at these frame rates.

At 2560x1440, the balance shifts toward the GPU. The frame rate drop from 1080p to 1440p is consistent across presets: Low drops from 214.4 to 165.2 FPS (a 22.9% reduction), Medium from 160.8 to 115.2 FPS (a 28.4% reduction), High from 135.0 to 96.2 FPS (a 28.7% reduction), and Ultra from 102.6 to 69.5 FPS (a 32.3% reduction). The increasing percentage drop with higher presets indicates that the GPU is the primary limiter at 1440p, particularly at Ultra where the pixel fill and shading demands outpace the CPU's influence.

At 3840x2160, the GPU dominates entirely. The frame rate reductions from 1440p to 4K are steep: Low drops from 165.2 to 96.9 FPS (a 41.3% reduction), Medium from 115.2 to 69.0 FPS (a 40.1% reduction), High from 96.2 to 54.4 FPS (a 43.5% reduction), and Ultra from 69.5 to 40.8 FPS (a 41.3% reduction). These near-uniform reductions across all presets confirm that the RX 7900 XT's rasterization throughput is the limiting factor at 4K, regardless of settings. The CPU's contribution is effectively masked at this resolution, as even the Low preset cannot exceed 96.9 FPS.

The Verdict

The Intel Core i5-13400F and AMD Radeon RX 7900 XT combination can run Rust successfully at all three tested resolutions, but the settings ceiling varies. At 1920x1080, the system clears 60 FPS on every preset, with Ultra achieving 102.6 FPS — a strong result for high-refresh-rate monitors. At 2560x1440, Ultra remains playable at 69.5 FPS, making this the highest quality configuration that still meets the 60 FPS threshold. At 3840x2160, only Low (96.9 FPS) and Medium (69.0 FPS) are playable; High and Ultra fall below 60 FPS. The verdict is clear: this PC is a capable 1080p and 1440p Ultra machine, and a 4K Medium system. Gamers prioritizing 4K should stick to Medium, while those at 1440p can enjoy maximum settings without compromise. The ranking of 701 out of 3,723 confirms that this is a top-tier combination for Rust, with only a small fraction of tested systems delivering better overall performance.
