Rust

The Intel Core i5-13400F and NVIDIA GeForce RTX 3080 Ti combination delivers a versatile 1080p and 1440p experience in Rust, with performance scaling that clearly identifies the GPU as the primary bottleneck at higher resolutions. The data shows a sharp drop in frame rates as resolution increases, but the system retains playability even at 4K with adjusted settings.

Resolution Scaling

The measured FPS data reveals a classic GPU-bound scaling pattern. At 1080p with Low settings, the combo produces 212.6 FPS, which drops to 153.6 FPS at 1440p and further to 93.8 FPS at 4K. This represents a 55.9% reduction from 1080p to 4K at Low settings, indicating that the RTX 3080 Ti is the limiting factor as pixel count increases. The GPU’s 12 GB of GDDR6X memory and 912.4 GB/s bandwidth are sufficient for Rust at all tested resolutions, but the render load at 4K overwhelms the graphics processor.

At Medium settings, the scaling is steeper: 152.6 FPS at 1080p, 106.2 FPS at 1440p, and 58.8 FPS at 4K. The 4K figure is 61.5% lower than the 1080p result, showing that the additional shading work from Medium settings amplifies the resolution penalty. High settings follow a similar trajectory: 129.4 FPS at 1080p, 89.5 FPS at 1440p, and 51.8 FPS at 4K. The gap between 1440p and 4K at High settings is 42.1%, which is slightly less than the Medium settings gap of 44.6%, suggesting diminishing returns on GPU load as settings climb.

Ultra settings reveal the most dramatic scaling. The combo achieves 98.7 FPS at 1080p, 67 FPS at 1440p, and just 37 FPS at 4K. The 4K Ultra result is 62.5% below 1080p Ultra, confirming that this configuration cannot sustain high refresh rates at maximum quality in 4K. The data indicates that the CPU, with its 10 cores and 16 threads, has sufficient headroom at 1080p to push frame rates above 200 FPS at Low settings, but the GPU’s 34.10 TFLOPS of FP32 compute becomes the hard ceiling as resolution scales.

Settings Recommendations

The benchmark results indicate that Ultra settings are only viable at 1080p for this combo. The 98.7 FPS average at 1080p Ultra is playable, but the drop to 67 FPS at 1440p Ultra and 37 FPS at 4K Ultra makes those configurations unsuitable for smooth gameplay. The data shows that Medium settings offer the best balance of visual quality and performance across all resolutions. At 1440p Medium, the combo delivers 106.2 FPS, which is 19.7% higher than High settings at the same resolution and 36.9% higher than Ultra.

For 4K users, Low settings are the only viable option, with 93.8 FPS. High settings at 4K produce 51.8 FPS, which is borderline but may be acceptable for slower-paced survival gameplay. The measured results show that Medium settings at 4K yield 58.8 FPS, which is 13.5% better than High but still below the 60 FPS threshold. The recommendation is to prioritize Medium settings at 1440p for the best experience, as this configuration provides 106.2 FPS while retaining more visual fidelity than Low. At 1080p, the choice between High (129.4 FPS) and Ultra (98.7 FPS) depends on whether the player values higher frame rates or maximum detail, with Medium (152.6 FPS) available for competitive play.

Measured FPS Breakdown

At 1920x1080, the combo delivers its strongest results. Low settings produce 212.6 FPS, Medium settings 152.6 FPS, High settings 129.4 FPS, and Ultra settings 98.7 FPS. The scaling from Low to Ultra is a 53.6% reduction, showing that settings have a substantial impact at 1080p. The 1080p results indicate the CPU and GPU work well together, with no single component dominating the frame rate.

Moving to 2560x1440, the frame rates drop across all settings. Low settings yield 153.6 FPS, which is 27.8% lower than 1080p Low. Medium settings produce 106.2 FPS, a 30.4% reduction. High settings achieve 89.5 FPS, down 30.8% from 1080p. Ultra settings fall to 67 FPS, a 32.1% decrease. The consistent percentage drops across settings suggest that the GPU’s rendering load scales uniformly with resolution.

At 3840x2160, the performance hit is more pronounced. Low settings produce 93.8 FPS, which is 38.9% lower than 1440p Low. Medium settings drop to 58.8 FPS, a 44.6% reduction. High settings yield 51.8 FPS, down 42.1%. Ultra settings fall to 37 FPS, a 44.8% decrease. The 4K results show that the RTX 3080 Ti, despite its 28,300 million transistors and 10240 shading units, cannot maintain high frame rates at this resolution with anything above Low settings.

GPU Role

The NVIDIA GeForce RTX 3080 Ti is the dominant component in this pairing. With 12 GB of GDDR6X memory on a 384-bit bus, the GPU provides 912.4 GB/s of bandwidth, which is more than adequate for Rust’s texture streaming. The boost clock of 1665 MHz drives 34.10 TFLOPS of FP32 performance, and the 80 RT cores and 320 tensor cores are available for ray-traced effects, though the measured data does not include RT-specific benchmarks. The GPU’s 83rd percentile ranking among all GPUs, with an average benchmark score of 41224, places it near the RTX 3090, which scores 41441 with a 0.5% higher delta.

The 4K results demonstrate the GPU’s limitations. The 37 FPS at 4K Ultra indicates that the 10240 shading units and 112 ROPs are saturated by the pixel workload. The pixel rate of 186.5 GPixel/s and texture rate of 532.8 GTexel/s are high, but Rust’s large open-world environments require substantial fill rate. The GPU’s 350 W TDP and 1x 12-pin power connector suggest it is a high-power part, and the suggested 750 W PSU is appropriate for this configuration. The GPU’s performance in Rust aligns with its position between the RTX 3090 and RTX 5070 in general benchmarks, though the game-specific results show it excels at 1080p and 1440p.

CPU Role

The Intel Core i5-13400F provides a strong foundation for this combo. With 10 cores (6 performance and 4 efficiency) and 16 threads, the CPU offers robust multi-threaded performance. The base clock of 2.50 GHz boosts to 4.60 GHz, and the 20 MB of shared L3 cache helps reduce memory latency in game scenarios. The CPU’s 82nd percentile ranking among all CPUs, with an average benchmark score of 25236, places it nearly level with the Intel Core i7-13620H (25201, 0.1% delta) and AMD Ryzen 5 5600X3D (25365, 0.5% delta).

In Rust, the CPU’s influence is most visible at 1080p Low, where the combo achieves 212.6 FPS. This high frame rate suggests the 16 threads are sufficient to keep the GPU fed at lower resolutions. The 3DMark 16-thread score of 7314 and Cinebench R23 multi-core score of 21279 indicate strong parallel processing capability, which is relevant for Rust’s physics and world simulation. However, the data shows that at 4K, the CPU becomes less relevant as the GPU takes over as the bottleneck. The 10-core design with a 65 W TDP is efficient, and the L3 cache of 20 MB helps with the game’s asset streaming. The CPU’s single-thread performance, measured at 3004 in Cinebench R23, is adequate for the game’s primary game thread, though the boost clock of 4.60 GHz is not exceptional compared to higher-end parts.

How This Combo Ranks

This specific combination of the Intel Core i5-13400F and NVIDIA GeForce RTX 3080 Ti ranks 401 out of 1717 tested combos in Rust. This places the system in the top 23.4% of all tested configurations, indicating solid performance for the hardware. The rank reflects the balance between the CPU’s 82nd percentile and the GPU’s 83rd percentile standings, showing that neither component is severely mismatched for this game.

The combo’s ranking is driven by the GPU’s ability to handle 1440p gaming well, with High settings achieving 89.5 FPS. The CPU’s 3DMark scores, including 7314 for 16 threads and 960 for single-thread, show that the processor can support high frame rates without bottlenecking. The rank of 401 suggests that while this is not a top-tier system, it outperforms the majority of tested hardware. The GPU’s proximity to the RTX 3090 in general benchmarks, with a mere 0.5% difference, further solidifies the system’s position. For Rust specifically, the data shows the combo is well-suited for 1080p and 1440p play, with 4K requiring significant settings compromises. The 401st rank out of 1717 combos is a strong result, placing this system ahead of roughly three-quarters of all tested configurations.
