Rust

The Intel Core i5-14400F paired with the NVIDIA GeForce RTX 4080 is an exceptionally strong combination for running Rust, a survival title that places heavy demands on both CPU and GPU. Measured benchmark data confirms that this configuration is not merely playable but delivers high refresh-rate performance across most settings, with only the most demanding 4K Ultra preset falling below the 60 FPS threshold. The data indicates that the RTX 4080’s raw graphics power is the primary driver, while the i5-14400F provides ample headroom to avoid bottlenecking at lower resolutions.

Measured FPS Breakdown

At 1920x1080, this combo delivers outstanding frame rates that easily exceed the 60 FPS playable threshold. The Low preset produces an average of 217 FPS, while the Medium preset yields 187 FPS with a minimum of 159 FPS and a maximum of 215 FPS. High settings average 163 FPS, and even the demanding Ultra preset maintains a robust 124 FPS average. These numbers indicate that the system is more than capable of high-refresh-rate gaming at 1080p, with all settings clearing the 60 FPS bar by a wide margin.

Moving to 2560x1440, performance remains excellent, though the scaling shows a predictable increase in GPU load. The Low preset averages 192 FPS, Medium delivers 133 FPS with a minimum of 113 FPS and a maximum of 153 FPS, and High reaches 112 FPS. Ultra settings still manage a strong 85 FPS average, confirming that even at 1440p, the RTX 4080 has sufficient headroom to run Rust at maximum visual fidelity without dipping below playable rates.

The 3840x2160 resolution reveals the first signs of strain, particularly at the highest settings. Low settings maintain a high 117 FPS average, Medium drops to 79 FPS with a minimum of 67 FPS and a maximum of 90 FPS, and High sits at 66 FPS. However, the Ultra preset falls to a 50 FPS average, which is below the 60 FPS playable threshold. This suggests that 4K gaming requires a trade-off between visual quality and frame rate, with High being the optimal choice for a smooth experience.

The data shows a consistent pattern: frame rates scale down as resolution and quality increase, but the system remains above 60 FPS for all settings except 4K Ultra. The gap between Low and Ultra presets is notable—at 1080p, the difference is 93 FPS, while at 1440p it is 107 FPS, and at 4K it is 67 FPS. This indicates that the GPU is the limiting factor at higher resolutions, while the CPU’s performance keeps the lower-resolution results from becoming CPU-bound.

Similar Performance Alternatives

The CPU’s nearest rivals, based on average benchmark scores, include the AMD Ryzen 7 PRO 8840U, which scores 32233 with a deltaPct of 0.1%, and the Intel Core i9-11900, scoring 32226 with a deltaPct of 0.2%. The AMD Ryzen 7 6800HS scores 32354 with a deltaPct of -0.2%, and the Intel Core i7-12800H scores 32121 with a deltaPct of 0.5%. These figures indicate that the i5-14400F’s performance is virtually indistinguishable from these alternatives, with deltas under 1%. For Rust, which benefits from strong single-core and multi-core performance, any of these CPUs would deliver similar frame rates when paired with the same GPU.

On the GPU side, the RTX 4080’s nearest rivals include the NVIDIA GeForce RTX 4080 SUPER, which scores 54209 with a deltaPct of 0.1%, and the AMD Radeon Pro W5700X, scoring 54828 with a deltaPct of -1.1%. The AMD Radeon RX 6750 GRE 12 GB scores 55698 with a deltaPct of -2.6%, and the AMD Radeon 8060S scores 55757 with a deltaPct of -2.7%. These results show that the RTX 4080 is closely matched with its direct successor, the RTX 4080 SUPER, while the AMD options score slightly higher on average. However, the deltaPct values are small, meaning that in-game performance for Rust would be very similar across these GPUs, with differences of only a few frames per second at most.

For a user considering alternatives, swapping the i5-14400F for any of the listed CPUs would produce negligible changes in Rust’s FPS, as the bottleneck at higher resolutions is the GPU. Conversely, replacing the RTX 4080 with an RTX 4080 SUPER would yield nearly identical results, while the AMD Radeon RX 6750 GRE 12 GB might offer a slight edge in synthetic benchmarks but not necessarily in real-world gameplay.

How This Combo Ranks

This specific combination of the Intel Core i5-14400F and NVIDIA GeForce RTX 4080 ranks 270th out of 3723 tested combos for Rust, placing it in the top 7.3% of all configurations. This ranking reflects the system’s ability to handle Rust’s demanding survival sandbox, which includes large open-world maps, dynamic lighting, and complex physics. The high ranking is driven primarily by the GPU’s strong performance, as the CPU’s 10 cores and 16 threads are sufficient to feed the RTX 4080 without creating a significant bottleneck.

The combo’s position in the 270th percentile is noteworthy because it places the system ahead of the vast majority of tested hardware, yet it is not at the absolute top. Higher-ranked combos likely include newer GPUs or CPUs with higher clock speeds, but the data shows that this pairing is more than adequate for competitive play and high-fidelity visuals. The ranking also suggests that the system can handle future game updates and additional mods that may increase CPU and GPU load, as it has substantial headroom above the minimum requirements.

The Verdict

Based on the measured FPS data and the 60 FPS playable threshold, this PC can run Rust successfully at all tested resolutions with specific settings. At 1920x1080, the system clears 60 FPS on every preset, from Low (217 FPS) to Ultra (124 FPS), making it ideal for high-refresh monitors. At 2560x1440, all presets also exceed 60 FPS, with Ultra achieving 85 FPS, which provides a smooth experience even at higher visual quality. At 3840x2160, the playable settings are High, Low, and Medium, with High being the best option at 66 FPS. The Ultra preset at 4K falls short at 50 FPS, so users prioritizing 4K should stick to High settings to maintain smooth gameplay.

The verdict by resolution confirms that the best settings for each resolution are High at 4K (66 FPS), Ultra at 1440p (85 FPS), and Ultra at 1080p (124 FPS). This indicates that the system is versatile enough to handle a range of display configurations, from competitive 1080p gaming to immersive 4K experiences with slight settings adjustments. For the vast majority of users, this combo will deliver an excellent Rust experience without compromises.

CPU and GPU Roles

The data reveals a clear division of labor between the CPU and GPU across different resolutions. At 1920x1080, the GPU is the primary bottleneck, as the i5-14400F’s strong single-core performance (evidenced by a Cinebench R23 single-core score of 3055 and a Geekbench single-core score of 2058) ensures that frame rates are limited by the RTX 4080’s rendering speed. The 217 FPS Low preset result at 1080p suggests that the CPU can push well beyond 200 FPS, but the GPU cannot keep up at higher settings.

As resolution increases to 2560x1440, the GPU becomes even more dominant, with the frame rate dropping by roughly 25-40% compared to 1080p across all presets. This is expected, as the number of pixels increases by 78%, placing a heavier load on the GPU’s shading units and memory bandwidth. The RTX 4080’s 716.8 GB/s of memory bandwidth and 48.74 TFLOPS of FP32 performance are sufficient to maintain high frame rates, but the scaling shows that the GPU is the limiting factor.

At 3840x2160, the GPU’s role becomes even more critical. The frame rate drops significantly, with Ultra falling to 50 FPS, which is below the playable threshold. This is a direct result of the GPU’s inability to process the 8.3 million pixels per frame at maximum quality. The CPU’s performance remains consistent, as the i5-14400F’s multi-core score of 21645 in Cinebench R23 indicates it can handle Rust’s simulation and world updates without issue. The data shows that the GPU is the component to upgrade for better 4K performance, while the CPU is sufficient for all tested resolutions.
