Rust

The Intel Core i5-13400F paired with the NVIDIA GeForce RTX 4080 is a high-end desktop combination that targets demanding survival titles like Rust. The benchmark data shows this pairing delivers strong performance across the board, with the RTX 4080 providing the bulk of the graphical horsepower while the i5-13400F handles the game’s simulation and networking threads. Measured frame rates range from a high of 213 FPS at 1920x1080 Low to a low of 50 FPS at 3840x2160 Ultra, indicating that the system is fully capable of smooth play at most settings, with only the most extreme 4K preset dipping below the 60 FPS playability threshold.

Similar Performance Alternatives

Looking at the nearestRivals data for the CPU, the Intel Core i5-13400F posts an average benchmark score of 25,292, which places it within a hair’s breadth of several alternative processors. The AMD Ryzen 9 6900HS scores 25,284, representing a 0% delta, meaning the two chips are effectively interchangeable in raw processing power for this game. Similarly, the AMD Ryzen 7 6800H comes in at 25,201 with a 0.4% delta, while the Intel Core 5 120 (25,362, -0.3%) and AMD Ryzen 5 5600X3D (25,365, -0.3%) also cluster tightly around this performance level. For Rust, which is known to be sensitive to single-threaded performance, the i5-13400F’s 3dmark_single_thread score of 960 and cinebench_r23_singlecore score of 3,191 suggest that any of these rivals would deliver nearly identical in-game behavior, especially at lower resolutions where the CPU becomes more relevant.

On the GPU side, the RTX 4080’s average benchmark score of 54,247 makes it a direct peer of the NVIDIA GeForce RTX 4080 SUPER, which scores 54,209 with a 0.1% delta. The AMD Radeon Pro W5700X (54,828, -1.1%), AMD Radeon RX 6750 GRE 12 GB (55,698, -2.6%), and AMD Radeon 8060S (55,757, -2.7%) all sit within a narrow performance band as well. What this means for Rust is that swapping the RTX 4080 for any of these near-identical alternatives would produce visually indistinguishable frame rates at the same settings and resolutions. The practical takeaway from the rival data is that this combo sits in a performance tier where small percentage differences (under 3% in all cases) do not translate into perceptible gameplay changes, so users should focus on other factors like driver stability or feature support rather than raw FPS deltas.

CPU and GPU Roles

The division of labor between the i5-13400F and RTX 4080 in Rust becomes clear when examining the scaling across resolutions and presets. At 1920x1080, the GPU is not the limiting factor: the Low preset yields 213 FPS, which is 50 FPS higher than the High preset’s 163 FPS, and the Ultra preset still holds at 124 FPS. This wide spread indicates that the CPU can feed the GPU enough frames at 1080p, but the settings themselves alter the workload distribution. Moving to 2560x1440, the Low preset drops to 188 FPS (a 25 FPS decrease from 1080p), while Ultra falls to 85 FPS (a 39 FPS decrease), showing that the GPU begins to take on more responsibility as pixel count rises. At 3840x2160, the trend accelerates: Low plunges to 117 FPS (71 FPS below the 1080p Low result), and Ultra collapses to 50 FPS, which is 74 FPS below the 1080p Ultra figure.

The data implies that the RTX 4080 is the dominant component at 4K, where the gap between Low and Ultra is 67 FPS (117 vs 50), while at 1080p that same gap is 89 FPS (213 vs 124). The CPU’s role becomes more visible at 1080p and 1440p, where the i5-13400F’s 10 cores and 16 threads keep the minimum frame rates from collapsing—for instance, the Medium preset at 1440p shows a min FPS of 113 against an average of 133, a relatively tight band. At 4K, the RTX 4080’s 16 GB of GDDR6X memory and 716.8 GB/s bandwidth are clearly the bottleneck for Ultra settings, as the average FPS falls to 50, below the playable threshold of 60. In summary, the CPU governs the upper FPS ceiling at lower resolutions, while the GPU dictates whether the system can sustain 60 FPS at higher resolutions and presets.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest performance across all presets. The Low setting produces an average of 213 FPS, which is the single highest measured value in the entire dataset. Medium follows at 183 FPS, with a minimum of 156 and a maximum of 211, showing a narrow 55 FPS range that indicates consistent frame pacing. High averages 163 FPS, while Ultra drops to 124 FPS—still well above the 60 FPS threshold. The 1080p results show a clear linear degradation from Low to Ultra, with each step up in quality costing roughly 20-30 FPS.

Stepping up to 2560x1440, the averages remain high but the gaps widen. Low produces 188 FPS, a 25 FPS reduction from 1080p, while Medium hits 133 FPS with a min of 113 and a max of 153. High sits at 112 FPS, and Ultra falls to 85 FPS. The min/max data for Medium at 1440p reveals a 40 FPS spread, which is tighter than the 55 FPS spread at 1080p Medium, suggesting that the higher resolution actually stabilizes frame delivery because the GPU is more consistently utilized. At 4K (3840x2160), the numbers tell a different story: Low averages 117 FPS, Medium 79 FPS (min 67, max 90), High 66 FPS, and Ultra 50 FPS. The Medium preset’s min of 67 FPS is the only measured minimum above the 60 FPS threshold at 4K, while the average for Ultra falls 10 FPS short of playability. Notably, the 4K High preset averages 66 FPS, which clears the threshold but with no min/max data provided, so real-world dips could be tighter.

The Verdict

The verdictByResolution data is unambiguous: this PC can run Rust at playable frame rates in every resolution tested, with one exception. At 1920x1080, all four presets—Low (213 FPS), Medium (183 FPS), High (163 FPS), and Ultra (124 FPS)—clear the 60 FPS threshold with massive headroom. At 2560x1440, the same is true: Low (188 FPS), Medium (133 FPS), High (112 FPS), and Ultra (85 FPS) all stay well above 60 FPS. The 3840x2160 resolution is the only area of concern, where Low (117 FPS), Medium (79 FPS), and High (66 FPS) are playable, but Ultra drops to 50 FPS, which is below the 60 FPS playability threshold. The data also lists the playable settings for each resolution: 4K has three playable presets (High, Low, Medium), while 1440p and 1080p have all four. In practical terms, a user can run Rust at 4K High with an average of 66 FPS, or drop to Medium for 79 FPS, but Ultra should be avoided at that resolution unless the user accepts sub-60 performance.

Best Settings per Resolution

For each resolution, the most demanding preset that maintains an average of at least 60 FPS is the optimal choice according to the measured data. At 3840x2160, the best setting is High, which delivers an average of 66 FPS—just 6 FPS above the threshold, making it a viable but not heavily headroom-laden choice. The verdictByResolution data confirms High as the best 4K preset, with Medium (79 FPS) and Low (117 FPS) as fallback options for higher frame rates. At 2560x1440, the best setting is Ultra, averaging 85 FPS. This is a sweet spot: it provides 25 FPS of headroom over the 60 FPS threshold while offering the highest visual fidelity. The 1440p Ultra result is 19 FPS higher than the 4K High result, demonstrating that the resolution drop more than compensates for the quality increase. At 1920x1080, the best setting is also Ultra, with an average of 124 FPS. This gives 64 FPS of headroom, making it the most comfortable high-quality experience in the dataset. The 1080p Ultra result is 39 FPS higher than 1440p Ultra and 58 FPS higher than 4K High, illustrating how resolution scaling impacts performance more than preset changes.

How This Combo Ranks

The Intel Core i5-13400F + NVIDIA GeForce RTX 4080 combination ranks 293rd out of 3,723 tested combos in Rust, placing it in the top 7.9% of all systems benchmarked. This percentile position is driven by the RTX 4080’s 86th percentile standing among all GPUs and the i5-13400F’s 77th percentile among all CPUs. The ranking suggests that while this is a high-end setup, it is not at the absolute top tier—there are 292 other combinations that deliver higher average FPS in Rust, likely featuring newer or more expensive components. However, the rank also indicates that this combo outperforms the vast majority of systems, and the measured FPS data supports this: even the worst-case scenario (4K Ultra at 50 FPS) is above the performance of typical mid-range systems, which would struggle to hit 60 FPS at 1440p. The combo’s strength lies in its balance—the CPU is not overkill for the GPU, and the GPU is not bottlenecked by the CPU at any resolution except possibly 1080p Low, where the 213 FPS result suggests the CPU is approaching its limit.
