Rust

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce GTX 1070 delivers a highly resolution-dependent experience in Rust. At 1080p, this combination is genuinely capable, clearing the 60 FPS threshold at Low, Medium, and High settings. However, at 1440p, only the Low preset remains playable, and at 4K, no settings achieve a smooth frame rate. The data shows a clear pattern: this is a 1080p-oriented pairing for Rust, with playability dropping off sharply as resolution increases.

Measured FPS Breakdown

The recorded measurements provide a complete picture of performance across three resolutions and four quality presets. All numbers represent average FPS, as minimum and maximum values were not captured in the database.

At 1920x1080, the combo performs best. The Low preset produces an average of 112.8 FPS, which is well above the 60 FPS playability threshold. Medium settings deliver 77.9 FPS, still comfortably playable. High settings drop to 66.4 FPS, remaining above 60 FPS but with less headroom. The Ultra preset falls to 47.5 FPS, which misses the playable mark. The scaling from Low to Ultra shows a 65.3 FPS drop, indicating that the GPU becomes the limiting factor at the highest preset.

At 2560x1440, performance declines noticeably. The Low preset averages 75.7 FPS, which is the only playable option at this resolution. Medium falls to 49.5 FPS, and High drops further to 42.7 FPS. Ultra sits at 32.2 FPS, which is the lowest recorded value at this resolution. The gap between Low and Ultra is 43.5 FPS, showing that preset selection has a major impact on playability.

At 3840x2160, the pairing struggles across the board. Low averages 49 FPS, which is the best result at 4K but still below 60 FPS. Medium drops to 33.4 FPS, High to 28.6 FPS, and Ultra to 22 FPS. None of these values approach the playability threshold. The difference between the best and worst 4K results is 27 FPS, but even the best case is insufficient for smooth gameplay.

The overall trend is consistent: each step from Low to Ultra reduces frame rates by roughly 15-25% at every resolution, and each resolution step from 1080p to 1440p to 4K imposes a significant performance penalty.

How This Combo Ranks

The database places this specific combination at rank 3071 out of 3723 tested combos for Rust. This percentile position, roughly in the bottom 18% of all tested configurations, reflects the GTX 1070's age and the demanding nature of Rust's rendering workload.

The ranking is driven more by the GPU than the CPU. The Ryzen 5 8400F sits in the 77th percentile among all CPUs, indicating strong processing capability. The GTX 1070, however, sits in the 47th percentile among all GPUs, which is a middling position. When combined, the weaker GPU drags the overall ranking down substantially.

In practical terms, this rank means the combo outperforms many older or lower-end configurations, but it lags behind the majority of modern pairings. For a game like Rust, which is known for heavy draw calls and environmental rendering, the GPU's limitations become pronounced at higher resolutions and presets. The rank of 3071 out of 3723 suggests that users with this setup should expect to play at 1080p with reduced settings for a smooth experience.

CPU and GPU Roles

The data reveals a clear division of labor between the two components. The Ryzen 5 8400F, with its 6 cores and 12 threads based on Zen 4 architecture, provides ample processing headroom. Its benchmark scores, including a Cinebench R23 multicore score of 20851 and a single-core score of 2943, indicate that CPU-bound scenarios are unlikely to be the primary bottleneck.

The GTX 1070, with 8 GB of GDDR5 memory and 1920 shading units, becomes the limiting factor at higher resolutions. The scaling between resolutions confirms this. At 1080p Low, the combo reaches 112.8 FPS, suggesting the CPU is feeding frames efficiently. When resolution increases to 1440p Low, FPS drops to 75.7, a 32.9% reduction. At 4K Low, it falls to 49 FPS, another 35.3% reduction from 1440p. These steep drops indicate that the GPU's pixel throughput and memory bandwidth are inadequate for higher pixel counts.

Preset scaling tells a similar story. At 1080p, moving from Low to Medium reduces FPS by 34.9, and from Medium to High by another 11.5. These reductions are consistent with GPU-bound rendering. The CPU's role is more evident at lower resolutions and presets, where it can maintain high frame rates, but its influence diminishes as the GPU becomes the limiting factor.

For this game, the CPU matters most at 1080p Low, where the combo achieves its highest FPS. At 1440p and 4K, the GPU dominates the performance equation, and the CPU's power is largely underutilized. Users considering upgrades should prioritize the GPU first, as the CPU has substantial headroom remaining.

Similar Performance Alternatives

The database provides nearest rivals for both components, offering insight into what other hardware would produce similar results.

For the CPU, the AMD Ryzen 5 8400F has an average benchmark score of 25005. The closest competitors are the AMD Ryzen 5 7500F, with a score of 24964 and a delta of 0.2%, and the Intel Core i7-11850H, scoring 24935 with a 0.3% delta. The Intel Core i7-13620H is also close at 24911, a 0.4% delta. On the higher end, the AMD EPYC 9474F scores 25103, a -0.4% delta. These rivals would behave nearly identically in CPU-bound scenarios, meaning any of them paired with the GTX 1070 would yield similar frame rates in Rust.

For the GPU, the NVIDIA GeForce GTX 1070 has an average benchmark score of 9780. Its nearest rivals include the AMD FirePro W5000, scoring 9803 with a -0.2% delta, and the NVIDIA Quadro M2000M at 9832, a -0.5% delta. The NVIDIA Tesla M10 scores 9724 with a 0.6% delta, and the NVIDIA Tesla C2070 scores 9716 with a 0.7% delta. These GPUs would produce comparable FPS results in Rust, though the professional-oriented cards may lack the gaming-specific optimizations of the GTX 1070.

Substituting any of these CPUs or GPUs into the combo would result in performance within 1% of the measured values. For practical purposes, users with these alternative components can expect the same playability conclusions: 1080p is viable at Low through High, 1440p is playable only at Low, and 4K is not playable at any setting.

FAQ

Q: Can this PC run Rust at 60 FPS?

A: Yes, at 1080p. The combo achieves 112.8 FPS on Low, 77.9 FPS on Medium, and 66.4 FPS on High. At 1440p, only Low reaches 75.7 FPS, which clears 60 FPS. At 4K, no preset reaches 60 FPS; the best is Low at 49 FPS.

Q: What is the best settings preset for 1080p?

A: The High preset is the best playable option, averaging 66.4 FPS. It provides the highest visual quality while remaining above the 60 FPS threshold. Ultra is not playable, averaging 47.5 FPS.

Q: Is the GTX 1070 the bottleneck in this configuration?

A: Yes, at higher resolutions. The CPU has a 77th percentile ranking, while the GPU sits at the 47th percentile. The steep FPS drops from 1080p to 1440p to 4K indicate the GPU's pixel throughput limits performance.

Q: How does this combo rank among all tested configurations for Rust?

A: It ranks 3071 out of 3723 tested combos, placing it in the lower 18% of all configurations. This rank reflects the GPU's middling position relative to current hardware.

Q: What resolution should I use for the best experience?

A: 1080p is the recommended resolution. It offers playable frame rates at three presets, with High providing the best balance of quality and performance at 66.4 FPS. At 1440p, only Low is playable, and at 4K, nothing is playable.

Q: Would a different CPU improve performance significantly?

A: No. The nearest CPU rivals, such as the Ryzen 5 7500F or the Core i7-13620H, score within 0.4% of the Ryzen 5 8400F. The GPU is the limiting factor, so CPU changes would yield minimal FPS gains.

The Verdict

This PC can run Rust, but only under specific conditions. At 1920x1080, the combo is genuinely playable: Low, Medium, and High presets all clear 60 FPS, with High being the best visually appealing option at 66.4 FPS. At 2560x1440, playability narrows to a single preset: Low, which averages 75.7 FPS. At 3840x2160, no settings achieve 60 FPS, with the best result being 49 FPS on Low.

The verdict is clear: this is a 1080p gaming system for Rust. Users with 1440p displays should stick to Low settings, and 4K is not a viable option. The Ryzen 5 8400F provides strong CPU performance, but the GTX 1070's age limits the combo to lower resolutions and presets. For a smooth experience, prioritize 1080p and choose High settings for the best balance. If higher resolutions are required, a GPU upgrade would be necessary, as the CPU has ample headroom for future improvements.
