Rust

The AMD Ryzen 5 8400F and AMD Radeon RX 580 form a pairing that mixes a modern 6-core Zen 4 processor with a 2017-era Polaris GPU. In Rust, a survival game released in 2018, the database has recorded average FPS across four presets and three resolutions. This analysis examines those measurements, the combo's ranking, and the roles each component plays.

Similar Performance Alternatives

The CPU and GPU each have close rivals in the database, meaning that swapping in any of these alternatives would produce nearly identical frame rates in Rust. The Ryzen 5 8400F has an average benchmark score of 25005, placing it in the 77th percentile of all CPUs. Its nearest rivals are the AMD Ryzen 5 7500F (24964, 0.2% higher), Intel Core i7-11850H (24935, 0.3% higher), Intel Core i7-13620H (24911, 0.4% higher), and AMD EPYC 9474F (25103, 0.4% lower). All deltas are under a single percentage point, so a system with any of these processors would behave essentially the same in CPU-bound scenarios.

For the GPU, the RX 580's average benchmark score is 12928, placing it in the 53rd percentile. Its nearest rivals are the NVIDIA GeForce RTX 3050 Ti Mobile (12940, 0.1% lower), NVIDIA GeForce GTX 1660 SUPER (12986, 0.4% lower), AMD Radeon 740M (12870, 0.5% higher), and AMD FirePro W5100 (12847, 0.6% higher). Again, the differences are negligible. A build with a GTX 1660 SUPER or an RTX 3050 Ti Mobile would deliver almost the same performance in Rust as this RX 580 configuration. The practical takeaway is that this combo is representative of a broad cluster of mid-range hardware from the same era.

How This Combo Ranks

The database ranks this CPU-GPU pairing at 3376 out of 3723 tested combinations for Rust. That places it in the lower portion of the ranking, with only a small number of combos performing worse. The rank reflects the overall FPS capability across all measured settings and resolutions. Given that the RX 580 is an end-of-life product while the Ryzen 5 8400F is a recent release, the low rank is not surprising. The CPU's 77th percentile standing suggests it is not the primary limitation, while the GPU's 53rd percentile indicates a mid-pack graphics chip. In Rust, which stresses both rendering and world simulation, the combination falls short of what many other tested systems achieve.

Measured FPS Breakdown

The database records only average FPS; no minimum or maximum values are available. The following table lists the recorded averages for each resolution and preset combination:

| Resolution | Settings | Avg FPS |

|------------|----------|---------|

| 3840x2160 | High | 15.0 |

| 3840x2160 | Low | 31.8 |

| 3840x2160 | Medium | 21.1 |

| 3840x2160 | Ultra | 14.8 |

| 2560x1440 | High | 30.8 |

| 2560x1440 | Low | 54.1 |

| 2560x1440 | Medium | 32.3 |

| 2560x1440 | Ultra | 23.8 |

| 1920x1080 | High | 44.9 |

| 1920x1080 | Low | 73.7 |

| 1920x1080 | Medium | 47.0 |

| 1920x1080 | Ultra | 34.9 |

At 4K, the highest average is 31.8 FPS on Low, which is far below the 60 FPS threshold. At 1440p, Low reaches 54.1 FPS, just short of 60, while all other presets fall below 33 FPS. At 1080p, Low is the only preset that clears 60, with 73.7 FPS. Medium and High sit at 47.0 and 44.9 respectively, and Ultra drops to 34.9.

The Verdict

Can this PC run Rust? The database's verdict is unambiguous: only at 1920x1080 with Low settings does the combo reach the 60 FPS playable threshold. The recorded average at that configuration is 73.7 FPS, providing a comfortable margin. At 2560x1440, no preset achieves 60 FPS; the best is Low at 54.1 FPS, which is below the threshold. At 3840x2160, even Low only manages 31.8 FPS, making 4K unplayable. Therefore, the system is playable only at 1080p with the lowest preset. Users who require higher settings or resolutions will need to upgrade the GPU, as the CPU is likely not the bottleneck given its strong benchmark standing.

CPU and GPU Roles

The recorded FPS scaling reveals which component dominates. At a fixed resolution, lowering the preset from Ultra to Low increases FPS substantially. For example, at 1080p, the jump from Ultra (34.9) to Low (73.7) is a large improvement. At 1440p, the same preset change goes from 23.8 to 54.1. At 4K, from 14.8 to 31.8. This consistent scaling with graphics settings indicates that the GPU's shading and memory throughput are the primary constraints. Resolution also has a large impact: at Low settings, moving from 1080p to 1440p drops FPS from 73.7 to 54.1, and to 4K it drops to 31.8. This is typical of a GPU-bound scenario. The CPU, with a 77th percentile rank and a Cinebench R23 multi-core score of 20851, is unlikely to be the limiting factor at these frame rates. The GPU's 53rd percentile and its 8 GB GDDR5 memory with a 256-bit bus are more indicative of the ceiling. The data implies that at 1080p Low, the CPU has enough headroom to feed the GPU, but at higher resolutions the GPU's raw pixel throughput becomes the bottleneck. In Rust, which is known for heavy world simulation, the CPU may still matter, but the measured FPS deltas across settings point to the GPU as the dominant factor for this pairing.

Best Settings per Resolution

Given the 60 FPS playable threshold, the database identifies the most demanding preset that stays at or above 60 FPS for each resolution. At 1920x1080, the only qualifying preset is Low, with an average of 73.7 FPS. Medium, High, and Ultra all fall below 60. At 2560x1440, no preset reaches 60 FPS; the best is Low at 54.1, which is below the threshold. Similarly, at 3840x2160, even Low is only 31.8 FPS. Therefore, the only playable configuration is 1080p Low. Users who want to play at higher resolutions must accept frame rates below 60 or upgrade the graphics card.

FAQ

Q: Can this CPU and GPU combo run Rust at 1920x1080 with 60 FPS?

A: Yes, but only with Low settings. The database records an average of 73.7 FPS at 1080p Low. Medium and High produce 47.0 and 44.9 FPS respectively, which are below the 60 FPS threshold.

Q: What is the best preset for 1440p with this combo?

A: None. At 2560x1440, the highest average FPS is 54.1 on Low, which does not reach 60 FPS. All other presets are below 33 FPS.

Q: How does the Ryzen 5 8400F compare to its closest rivals?

A: The Ryzen 5 8400F has an average benchmark score of 25005. Its nearest rivals are the AMD Ryzen 5 7500F (0.2% higher), Intel Core i7-11850H (0.3% higher), Intel Core i7-13620H (0.4% higher), and AMD EPYC 9474F (0.4% lower). These differences are negligible for gaming performance.

Q: What is the combo's rank among all tested systems in Rust?

A: It ranks 3376th out of 3723 tested combinations, placing it in the lower portion of the database.

Q: Is the RX 580 similar to the GTX 1660 SUPER?

A: The RX 580's average benchmark score is 12928, while the GTX 1660 SUPER scores 12986, which is 0.4% higher. This means they are effectively equivalent in performance, so a GTX 1660 SUPER would produce nearly identical frame rates in Rust.

Q: Why does the combo fail to reach 60 FPS at 1440p even on Low?

A: The RX 580's GPU resources are insufficient for that resolution. The data shows that at Low settings, 1440p yields 54.1 FPS, which is below the 60 FPS threshold. The GPU's 256-bit memory bus and 2304 shading units cannot push the pixel count fast enough.
