Rust

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 5080 is a combination that spans two very different performance tiers. The CPU is a solid mid-range desktop processor, while the GPU is a flagship Blackwell architecture part. For Rust, the data shows that this pairing produces a wide performance envelope, heavily dependent on resolution and quality settings. At 1080p, the system is overwhelmingly powerful, while at 4K Ultra, it finally meets its match, dropping just below the 60 FPS playability threshold. The following analysis breaks down the measured average frame rates, identifies the optimal settings per resolution, and ranks this combination against the broader benchmark database.

Measured FPS Breakdown

The measured FPS data for this configuration in Rust provides a clear picture of scaling across three resolutions and four quality presets. All figures are average FPS, as minimum and maximum frame rate data was not recorded for this test run.

At 3840x2160 (4K), the system produces a wide spread of results. On the Low preset, the average frame rate is 126.1 FPS, which is an exceptionally strong result for 4K. Moving to Medium reduces the average to 85.3 FPS, a significant drop of 40.8 FPS. The High preset yields an average of 69.9 FPS, which remains comfortably playable. The Ultra preset is the most demanding, bringing the average down to 54.0 FPS, which falls below the 60 FPS playability threshold. The scaling from Low to Ultra shows a performance degradation of 72.1 FPS, indicating that the GPU is the primary bottleneck at this resolution, with each step in quality having a substantial impact.

At 2560x1440 (1440p), the performance headroom is much more pronounced. The Low preset achieves an average of 181.7 FPS. The Medium preset averages 139.9 FPS, and High comes in at 119.3 FPS. The Ultra preset still manages an average of 90.7 FPS, which is well above the playable threshold. The gap between Low and Ultra is 91.0 FPS. This indicates that while the GPU is still heavily utilized, the CPU has enough headroom to feed it effectively, allowing for high frame rates even at the highest quality settings.

At 1920x1080 (1080p), the configuration is clearly CPU-bound at lower settings and still exceptionally fast at higher ones. The Low preset produces an average of 206.0 FPS. The Medium preset averages 179.2 FPS, and the High preset achieves 167.8 FPS. The Ultra preset, which is the most demanding, still yields a robust 133.5 FPS. The performance delta between Low and Ultra here is 72.5 FPS. Interestingly, the difference between High and Ultra at 1080p (34.3 FPS) is smaller than the difference between Medium and High (11.4 FPS), suggesting that the CPU is beginning to limit performance as the resolution drops and the frame rate climbs.

Best Settings per Resolution

Given the 60 FPS playable threshold, the data indicates the most demanding preset that remains playable at each resolution.

At 3840x2160, the High preset is the best choice, with an average of 69.9 FPS. While the Medium preset also clears the threshold at 85.3 FPS, High offers a better visual quality without dropping below the target. The Ultra preset, at 54.0 FPS, is not recommended for a consistent 60 FPS experience.

At 2560x1440, the system has enough performance to run the Ultra preset, which produces an average of 90.7 FPS. This is the highest quality setting available and it clears the 60 FPS requirement with a significant margin, making it the definitive best setting for this resolution.

At 1920x1080, the Ultra preset is also the best choice, achieving an average of 133.5 FPS. This provides a high-quality experience with frame rates far above the playable threshold. The system has ample performance at 1080p to run the most demanding settings without issue.

A: The measured average FPS at 2560x1440 with Medium settings is 139.9 FPS.

Q: Does the 4K Ultra preset meet the 60 FPS standard required for smooth gameplay?

A: No. The average FPS of 54.0 at 4K Ultra is below the 60 FPS playable threshold. To maintain a playable experience at 4K, you would need to use the High preset, which averages 69.9 FPS.

Similar Performance Alternatives

For the CPU, the Intel Core i5-12400F has an average benchmark score of 19039. Its nearest rivals are extremely close in performance. The AMD Ryzen 5 7535HS shows an average score of 19047, with a delta of 0%, meaning performance is effectively identical. Similarly, the Intel Core 3 201E and the AMD EPYC 7773X are within 0.3% of the i5-12400F's score. The Intel Core i5-1335U is also a close match, with a 0.3% delta. In practice, any of these processors would deliver a nearly indistinguishable experience in Rust, assuming the GPU is the same.

For the GPU, the NVIDIA GeForce RTX 5080 has an average benchmark score of 56083. Its nearest competitors show a mixed bag of performance. The AMD Radeon 8060S scores 55757, a 0.6% difference. The AMD Radeon RX 6750 GRE 12 GB scores 55698, a 0.7% delta. The AMD Radeon Pro W5700X is 2.3% slower. On the other hand, the AMD Radeon RX 9070 GRE is 2.2% faster, with a score of 57367. This suggests that in Rust, the RTX 5080 would perform almost identically to the Radeon 8060S, while the RX 9070 GRE might offer a slight edge in frame rates.

How This Combo Ranks

In the database of tested combinations for Rust, this pairing of the Intel Core i5-12400F and NVIDIA GeForce RTX 5080 ranks 239th out of 3723 tested combos. This places the system in the top 6.4% of all tested configurations. This high ranking is a direct result of the RTX 5080's immense rasterization power, which allows the system to post high average frame rates even at 4K resolution. While the CPU is a more modest performer, its capabilities are sufficient to avoid being a major bottleneck at higher resolutions, allowing the GPU to shine.

The Verdict

The data confirms that this PC can run Rust effectively across most resolution and quality settings. At 1920x1080, the system clears the 60 FPS threshold on all presets, with the Ultra preset achieving an average of 133.5 FPS. This makes it an excellent choice for high-refresh-rate 1080p gaming. At 2560x1440, the verdict is equally positive; all presets, including Ultra, are playable, with the Ultra preset hitting 90.7 FPS. This is the sweet spot for this combination, offering high visual quality and a high frame rate. At 3840x2160, the system is slightly less dominant. The High preset is the best playable option at 69.9 FPS. The Ultra preset, at 54.0 FPS, is not playable by the 60 FPS standard. Therefore, for 4K gaming, you must sacrifice the Ultra preset for High to maintain smooth gameplay.

CPU and GPU Roles

The benchmark data shows a clear shift in system bottleneck depending on the resolution. At 1920x1080, the CPU likely becomes the primary limiting factor, especially on the Low preset where the average FPS reaches 206.0. The frame rate scaling from 1080p to 1440p on the Low preset (206.0 to 181.7 FPS) is relatively modest, suggesting the CPU is struggling to keep up with the GPU's output. At 2560x1440, the balance shifts towards the GPU. The scaling from Medium to High at 1440p (139.9 to 119.3 FPS) shows a more linear relationship with GPU load. At 3840x2160, the GPU is unequivocally the dominant component. The frame rate drop from 126.1 FPS on Low to 54.0 FPS on Ultra is a massive 72.1 FPS difference, demonstrating that the RTX 5080's rendering capabilities are the sole determinant of performance. The CPU has ample headroom at this resolution to feed the GPU, meaning that any performance gains would need to come from GPU adjustments. In summary, for Rust, the GPU dictates performance at 4K, while the CPU plays a more significant role as resolution decreases and frame rates climb.
