Rust

The Intel Core i5-12400 paired with the AMD Radeon RX 6750 XT delivers a highly capable Rust experience, with performance scaling predictably across resolutions and presets. The measured data, derived from direct testing, shows that this combination is best suited for 1080p and 1440p gaming, where it can comfortably exceed the 60 FPS threshold at most settings. At 4K, the system struggles with higher presets but remains playable at the lowest setting. The following analysis breaks down the exact frame rates, optimal settings, and the relative standing of this combo against other tested hardware.

Measured FPS Breakdown

The benchmark results for Rust provide a clear picture of how the i5-12400 and RX 6750 XT handle the game’s engine. At 1920x1080, the combo is exceptionally strong. On Low settings, it achieves an average of 171.1 FPS, which is more than double the playable threshold. Moving to Medium yields 115.4 FPS, and High settings still produce a very smooth 97.3 FPS. The most demanding Ultra preset at 1080p still clears the 60 FPS bar with an average of 73.8 FPS, indicating that the GPU has enough headroom to handle maximum detail without dropping into uncomfortable territory.

Stepping up to 2560x1440, the performance drops are consistent but not drastic. Low settings produce an average of 120.5 FPS, which is still excellent for high-refresh-rate monitors. Medium settings follow with 82.3 FPS, and High settings maintain 69.6 FPS, staying clear of the 60 FPS line. However, Ultra at 1440p falls to 53.7 FPS, which is below the playable threshold and signals that this preset is too demanding for the GPU at this resolution.

At 3840x2160, the RX 6750 XT begins to show its limits. Low settings yield an average of 71.3 FPS, which is just above the playable line and makes 4K gaming possible, but only with reduced visual fidelity. Medium drops to 49.2 FPS, High falls to 40.9 FPS, and Ultra bottoms out at 32.9 FPS. None of these higher presets are suitable for smooth gameplay at 4K, as they all fall significantly below the 60 FPS target. The data shows a clear pattern: the GPU is the primary bottleneck at higher resolutions, while the CPU has ample headroom to keep up with the frame generation demands at 1080p and 1440p.

Best Settings per Resolution

Based on the measured averages, the optimal preset for each resolution is the most demanding one that maintains an average of at least 60 FPS.

At 1920x1080, the best settings are Ultra, which delivers an average of 73.8 FPS. This is a strong result, as it allows players to enjoy the game with all visual features enabled without sacrificing fluidity. The 1080p resolution is clearly the sweet spot for this combo.

For 2560x1440, the best settings are High, producing 69.6 FPS. While Medium and Low also pass the threshold, High offers a better visual experience while still staying comfortably above 60 FPS. The jump from High to Ultra is too steep, as the latter drops to 53.7 FPS, making it unplayable by the set standard.

At 3840x2160, the only playable setting is Low, which averages 71.3 FPS. This is a marginal pass, and while it technically clears the bar, the visual compromise is significant. The other presets at 4K — Medium at 49.2 FPS, High at 40.9 FPS, and Ultra at 32.9 FPS — are all below the 60 FPS threshold and should be avoided for competitive or smooth play.

How This Combo Ranks

In the broader database of tested combinations, this specific pairing of the i5-12400 and RX 6750 XT ranks 1643rd out of 3723 tested combos for Rust. This places it in the upper-middle tier of systems, indicating that it performs better than a majority of other configurations, but it is not at the top end of the spectrum. The rank reflects a balanced setup that handles the game well at mainstream resolutions, but it is not designed to push 4K Ultra settings or extreme frame rates.

The percentile data supports this assessment. The CPU sits in the 72nd percentile among all processors, while the GPU is in the 71st percentile among all graphics cards. This alignment means neither component is significantly holding back the other in this title, though the GPU will become the limiting factor as resolution increases. The combo’s rank is a direct result of this balanced pairing, which provides a solid foundation for Rust at 1080p and 1440p, but does not have the raw power to dominate at 4K.

Similar Performance Alternatives

Looking at the nearest rivals for the CPU and GPU provides context for what other hardware would behave similarly in Rust. The i5-12400’s closest peers in terms of average benchmark score include the AMD EPYC 7643, which is 0.1% slower, and the Intel Core i7-1355U, which is 0.3% slower. The AMD Ryzen AI 5 330 is 0.7% slower, while the Intel Core i3-14100F is actually 0.9% faster. These deltas are all within a single percentage point, meaning that swapping the i5-12400 for any of these chips would yield nearly identical performance in CPU-bound scenarios, such as the lower-resolution, high-frame-rate cases at 1080p.

On the GPU side, the RX 6750 XT’s nearest rivals are the AMD Radeon R9 M395X, which is 0.5% faster, and the AMD FirePro W7100, which is 0.6% faster. The AMD FirePro D700 is 0.7% faster, and the NVIDIA GeForce RTX 3080 Ti Mobile is 1.1% faster. These are all very close in aggregate score, so a system with any of these GPUs would produce frame rates that are nearly indistinguishable from the RX 6750 XT in Rust. The practical takeaway is that this performance tier is consistent; moving to a slightly faster or slower component would not change the playability verdicts at any resolution.

CPU and GPU Roles

The scaling between resolutions and presets reveals which component dominates in Rust. At 1920x1080, the difference between Low and Ultra settings is notable — 171.1 FPS versus 73.8 FPS — which indicates the GPU is doing most of the work, as increasing visual fidelity directly impacts frame rates. However, the CPU must also be capable of feeding those high frame rates, and the i5-12400 does so without issue, as evidenced by the strong 1080p numbers.

When moving from 1080p to 1440p, the average FPS drops by roughly 30-40% across all presets. For example, High goes from 97.3 FPS to 69.6 FPS, and Ultra goes from 73.8 FPS to 53.7 FPS. This drop is consistent with a GPU-bound scenario, where the render resolution is the primary factor. The CPU’s role becomes less critical as resolution increases, because the frame rate ceiling is lowered, giving the processor more time to prepare frames.

At 3840x2160, the GPU is clearly the limiting factor. The Low preset at 71.3 FPS is the only one that clears the threshold, and the steep decline to 32.9 FPS at Ultra shows that the RX 6750 XT is overwhelmed by the pixel count. The i5-12400 is not the bottleneck here; even the most demanding 4K preset would benefit more from a faster GPU than a faster CPU. In summary, the CPU is sufficient for all tested scenarios, while the GPU determines playability at higher resolutions and presets.

The Verdict

The data confirms that this PC can run Rust effectively, but with caveats depending on the target resolution. At 1920x1080, the system is fully capable, with Ultra settings achieving 73.8 FPS, which clears the 60 FPS threshold with room to spare. This is the ideal environment for this combo, offering the best visual quality and smooth performance.

At 2560x1440, the system remains playable at High settings, with 69.6 FPS. This is a solid result for a 1440p monitor, though players who insist on Ultra will need to lower the preset, as it falls to 53.7 FPS. For most users, High at 1440p strikes the right balance between fidelity and speed.

At 3840x2160, the verdict is more restrictive. The only playable setting is Low, which delivers 71.3 FPS. This is technically above the 60 FPS line, but it requires sacrificing most graphical features. The other presets — Medium at 49.2 FPS, High at 40.9 FPS, and Ultra at 32.9 FPS — are all below the threshold and not recommended for a smooth experience. Ultimately, this system is a strong choice for 1080p and a good choice for 1440p, but it is only marginally suitable for 4K on the lowest settings.
