Rust

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 4070 pairing delivers a strong Rust experience across most resolutions, with the data showing a clear path to 60 FPS at 1440p and 1080p, while 4K requires a settings compromise. This combination of a Zen 4-based six-core CPU and an Ada Lovelace GPU produces measured frame rates that scale predictably with resolution and preset, making it a versatile choice for the survival title.

Measured FPS Breakdown

The measured performance data for Rust reveals a clear hierarchy across the three tested resolutions and four quality presets. At 3840x2160, the AMD Ryzen 5 8400F and NVIDIA GeForce RTX 4070 combination starts at 91 FPS average on Low settings, which is the only 4K preset that comfortably exceeds the 60 FPS playable threshold. Dropping to Medium at 4K yields a 61 FPS average with a minimum of 52 FPS and a maximum of 71 FPS, placing it right at the edge of playability. High settings at 4K reduce the average to 52 FPS, while Ultra plunges to 39 FPS average, both falling short of smooth gameplay.

Moving to 2560x1440, the same hardware shows substantially more headroom. Low settings produce a 155 FPS average, which is more than double the 60 FPS target. Medium settings deliver 104 FPS average with a measured range of 88 to 120 FPS, indicating consistent frame delivery. High settings at 1440p achieve an 88 FPS average, and even Ultra maintains a 67 FPS average, clearing the playability bar with room to spare. The 1440p results confirm that this CPU-GPU combo has sufficient compute headroom for Rust at this resolution, with even the most demanding preset staying above 60 FPS.

At 1920x1080, performance becomes abundant. Low settings hit a 216 FPS average, which is exceptional for a game with Rust's simulation overhead. Medium settings produce 151 FPS average with a minimum of 128 FPS and a maximum of 174 FPS, showing tight frame pacing. High settings reach 127 FPS average, while Ultra still manages a 97 FPS average. The 1080p data demonstrates that this pairing is nowhere near CPU or GPU bound at this resolution, with all presets delivering far more than the 60 FPS playable threshold.

The frame rate deltas between presets are informative. At 4K, the gap from Low to Medium is 30 FPS, from Medium to High is 9 FPS, and from High to Ultra is 13 FPS. This suggests that the Medium to High transition is relatively small in performance cost, while Low to Medium and High to Ultra are more significant jumps. At 1440p, the deltas are 51 FPS from Low to Medium, 16 FPS from Medium to High, and 21 FPS from High to Ultra, indicating that Low is disproportionately fast compared to the other presets. At 1080p, the deltas are 65 FPS from Low to Medium, 24 FPS from Medium to High, and 30 FPS from High to Ultra, following a similar pattern.

Minimum and maximum frame data is only available for the Medium preset at each resolution. At 4K Medium, the 52 FPS minimum versus the 61 FPS average shows a 15% dip below the mean, which can cause occasional stutter. At 1440p Medium, the 88 FPS minimum versus the 104 FPS average represents a 15% deviation, still smooth in practice. At 1080p Medium, the 128 FPS minimum versus the 151 FPS average shows a similar 15% drop, but the absolute floor is high enough to remain imperceptible.

Similar Performance Alternatives

The AMD Ryzen 5 8400F sits in a narrow performance band according to its average benchmark score of 25005. Its closest rival is the AMD Ryzen 5 7500F, which scores 24964, a delta of only 0.2%. This means the 8400F is effectively identical in synthetic CPU benchmarks to the 7500F, and users upgrading between these two would see no measurable difference in Rust frame rates. The Intel Core i7-11850H scores 24935, a 0.3% delta, making it another near-identical performer, although this is a mobile processor that would not typically be paired with a desktop GPU like the RTX 4070. The Intel Core i7-13620H scores 24911, a 0.4% delta, again very close. On the other side, the AMD EPYC 9474F scores 25103, a -0.4% delta, meaning the 8400F is slightly slower than this server chip, but the difference is negligible for gaming. The percentileVsAllCpus of 77 indicates the 8400F outperforms over three-quarters of all tested CPUs, reinforcing that it is a solid mid-range choice.

For the GPU, the NVIDIA GeForce RTX 4070 has an average benchmark score of 37648 and a percentileVsAllGpus of 81. Its nearest rival is the NVIDIA Tesla P4, which scores 37628, a delta of 0.1%, making them statistically equivalent in synthetic benchmarks, though the Tesla P4 is a data-center card with different driver optimizations. The AMD Radeon RX Vega 56 scores 37507, a 0.4% delta, indicating the RTX 4070 is only slightly faster in aggregate compute tests. The NVIDIA GeForce RTX 4080 Mobile scores 38135, a -1.3% delta, meaning the desktop RTX 4070 is actually 1.3% slower than this laptop GPU, which is notable given the power and thermal constraints of mobile parts. The AMD Radeon PRO W6400 scores 37157, a 1.3% delta, showing the RTX 4070 holds a modest lead over this workstation card. In practical Rust gameplay, these synthetic deltas translate to frame rate differences of only a few percent, so users with any of these GPUs would experience similar performance at the same settings.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is Medium, which achieves a 61 FPS average. This is the optimal choice for 4K gaming, as it balances visual quality with playable frame rates. Low settings would offer a higher 91 FPS average, but Medium provides better visuals while still clearing the 60 FPS bar. High and Ultra at 4K fall below 60 FPS, with averages of 52 and 39 respectively, making them unsuitable for smooth play.

At 2560x1440, the best settings option is Ultra, which delivers a 67 FPS average. This is the highest preset available, and the data shows it remains playable. Users can choose any preset at 1440p and stay above 60 FPS, with Low at 155 FPS, Medium at 104 FPS, and High at 88 FPS, but Ultra offers the maximum visual fidelity without sacrificing playability.

At 1920x1080, the best settings are also Ultra, with a 97 FPS average. This provides a comfortable margin above the 60 FPS threshold, and the frame rate is high enough for competitive play. All presets at 1080p are playable, with Low at 216 FPS, Medium at 151 FPS, and High at 127 FPS, but Ultra is the recommended choice for the best visual experience.

The pattern is clear: the AMD Ryzen 5 8400F and RTX 4070 combination can handle Ultra settings at 1440p and 1080p, but requires a drop to Medium at 4K to maintain 60 FPS. The playableThresholdFps of 60 is met by Low and Medium at 4K, and by all four presets at 1440p and 1080p.

The Verdict

The data confirms that this PC can run Rust effectively, but with resolution-dependent limitations. At 3840x2160, the verdictByResolution shows playable settings of Low and Medium, with Medium being the best at 61 FPS average. This means 4K users can achieve smooth gameplay, but only at reduced quality settings. High and Ultra at 4K are not viable, as they drop to 52 and 39 FPS averages respectively, which fall below the 60 FPS playable threshold.

At 2560x1440, the verdict is unequivocal: all four settings—High, Low, Medium, and Ultra—are playable, with Ultra being the best at 67 FPS average. This makes 1440p the sweet spot for this hardware combination, offering full visual fidelity without frame rate compromises. The measured data shows that even the most demanding preset clears the 60 FPS bar by a comfortable 7 FPS margin.

At 1920x1080, the verdict is similarly positive, with all four settings playable and Ultra as the best at 97 FPS average. This resolution provides the highest frame rates, with even Ultra nearly hitting triple digits. For users prioritizing frame rate over resolution, 1080p Ultra is the optimal configuration.

Overall, the AMD Ryzen 5 8400F and NVIDIA GeForce RTX 4070 is a capable Rust machine. The CPU's 6 cores and 12 threads, with a boost clock of 4.70 GHz, provide sufficient single-thread performance for Rust's simulation-heavy gameplay, as evidenced by the 3dmark_single_thread score of 951 and the cinebench_r23_singlecore score of 2943. The GPU's 5888 shading units and 12 GB of GDDR6X memory with 504.2 GB/s bandwidth handle the game's rendering demands effectively. The combination ranks 888 out of 3723 tested combos, placing it in the top 24% of all tested hardware pairings, which supports the conclusion that it is above average for this title.
