Rust

The Intel Core i5-12400 and AMD Radeon RX 570 combination delivers a narrow band of playable performance in Rust, and the data shows that only one specific configuration crosses the 60 FPS threshold. At 1920x1080 with Low settings, the average frame rate reaches 63.4 FPS, which is the sole playable scenario recorded. Every other settings and resolution pairing falls short, with the gap widening dramatically as resolution and graphical load increase. The pattern is consistent: Rust is demanding on the GPU at higher resolutions, while the CPU has enough headroom to keep up at 1080p but cannot compensate for the video card's limits at 1440p or 4K. The recorded measurements provide a clear picture of where this hardware stands, and the analysis below breaks down each scenario.

Measured FPS Breakdown

At 1920x1080, the full range of presets was tested. Low settings produce an average of 63.4 FPS, which is the only result above the playable threshold. Medium settings drop to 44.6 FPS, High settings fall to 40.8 FPS, and Ultra settings bottom out at 26.5 FPS. The scaling from Low to Medium represents a 29.7% reduction in average frame rate, while moving from Medium to High costs another 8.5%, and High to Ultra costs an additional 35.0%. The data indicates that each step up in preset imposes a significant penalty, but the jump from High to Ultra is particularly severe.

At 2560x1440, none of the presets reach 60 FPS. Low settings average 46.1 FPS, which is the best result at this resolution. Medium averages 31.2 FPS, High averages 25.2 FPS, and Ultra averages 20.5 FPS. The transition from 1080p Low to 1440p Low costs 17.3 FPS, or 27.3% of the 1080p score. The relative drop is consistent across presets: 1440p Medium is 30.0% slower than 1080p Medium, 1440p High is 38.2% slower, and 1440p Ultra is 22.6% slower. The data shows that 1440p is a significant hurdle, with even the lowest settings falling 13.9 FPS short of the playable threshold.

At 3840x2160, performance collapses. Low settings average 29.4 FPS, Medium averages 18.4 FPS, High averages 15.8 FPS, and Ultra averages 11.5 FPS. The gap between 1440p Low and 4K Low is 16.7 FPS, a 36.2% reduction. The gap between 1080p Low and 4K Low is 34.0 FPS, meaning 4K delivers less than half the frame rate of 1080p at the same preset. The data also shows diminishing returns as resolution increases: the absolute FPS loss from 1080p to 1440p is larger than the loss from 1440p to 4K, but the relative impact is severe in both cases. No min or max frame data was recorded, so the averages represent the full picture.

FAQ

Q: Can this PC run Rust at 60 FPS on any settings?

A: Yes, but only at 1920x1080 with Low settings, where the average frame rate is 63.4 FPS. All other settings at 1080p, and all presets at 1440p and 4K, fall below 60 FPS.

Q: What is the best frame rate this combo can achieve at 2560x1440?

A: The highest average at 1440p is 46.1 FPS on Low settings. Medium, High, and Ultra produce 31.2, 25.2, and 20.5 FPS respectively, none of which approach 60 FPS.

Q: How does the RX 570 perform at 4K in this game?

A: Poorly. The best 4K result is 29.4 FPS on Low settings. Medium, High, and Ultra average 18.4, 15.8, and 11.5 FPS, making 4K effectively unplayable at any preset.

Q: What is the frame rate penalty for moving from Low to Ultra at 1080p?

A: The average drops from 63.4 FPS to 26.5 FPS, a reduction of 36.9 FPS or 58.2%. The largest single step is from High to Ultra, which costs 14.3 FPS.

Q: Is the CPU or GPU more responsible for the performance limits?

A: The data points to the GPU as the primary bottleneck at higher resolutions. The CPU scores well in synthetic benchmarks, but the frame rate drops sharply from 1080p to 1440p and 4K even on Low settings, indicating that the RX 570 cannot handle the pixel throughput required.

Q: Does the combo rank anywhere near the top of the database for Rust?

A: No. It ranks 3547 out of 3723 tested combos, placing it in the bottom 5% of all configurations recorded for this game.

CPU and GPU Roles

The recorded data reveals a clear division of labor between the Intel Core i5-12400 and the AMD Radeon RX 570. The CPU, with 6 cores and 12 threads, has a strong synthetic profile: its Cinebench R23 multi-core score is 15989 and single-core is 2257, with a Passmark multithread score of 18747. These numbers indicate a capable processor for handling game logic, physics, and entity management in Rust. However, the GPU is the limiting factor in most scenarios. The RX 570 has 2048 shading units and a memory bandwidth of 224.0 GB/s, but its 4 GB of GDDR5 memory and 5.095 TFLOPS of FP32 compute are modest by modern standards. The benchmark results show that at 1920x1080, the CPU can feed the GPU enough data to reach 63.4 FPS on Low, but at 2560x1440 and 3840x2160, the GPU simply cannot render enough pixels per frame. The frame rate drops of 27.3% from 1080p Low to 1440p Low and 36.2% from 1440p Low to 4K Low are consistent with a GPU-bound workload. At 1080p, the scaling between presets shows that the GPU is also the limiting factor when settings rise, as each increase in graphical detail reduces FPS substantially. The CPU appears to have headroom, as its performance stays constant regardless of resolution, but the GPU's output dictates the final frame rate. At 4K, the RX 570 is overwhelmed, and even Low settings only manage 29.4 FPS, which is 46.4% of the 1080p Low score. This confirms that any attempt to play Rust at higher resolutions will be constrained by the GPU, not the CPU.

The Verdict

This PC can run Rust, but only in a very narrow configuration. The verdict data shows that at 1920x1080, Low settings are the only playable option, with an average of 63.4 FPS. This clears the 60 FPS threshold by 3.4 FPS, which is a slim margin. At 2560x1440, there are no playable settings; the best result is 46.1 FPS on Low, which falls 13.9 FPS short. At 3840x2160, all presets are far below playable, with the best being 29.4 FPS on Low. For a smooth experience, the user is restricted to 1080p and must accept Low settings. Medium, High, and Ultra at 1080p produce 44.6, 40.8, and 26.5 FPS respectively, all below the threshold. The data suggests that this is a borderline build for Rust: it technically meets the 60 FPS target at the lowest settings, but there is no room for higher graphical fidelity without sacrificing playability. The user should expect to lower resolution or settings further if they want consistent frame times, as the average of 63.4 FPS leaves little margin for demanding scenes or multiplayer servers with many players.

Similar Performance Alternatives

Looking at the nearest rivals for both components provides context for what other hardware would behave similarly. For the Intel Core i5-12400, the closest matches are the AMD EPYC 7643 with an average score of 18697 (0.1% lower), the Intel Core i7-1355U at 18730 (0.3% lower), the AMD Ryzen AI 5 330 at 18811 (0.7% lower), and the Intel Core i3-14100F at 18519 (0.9% higher). These CPUs all sit within 1% of each other in average benchmark score, indicating that swapping the i5-12400 for any of these would produce nearly identical CPU-bound performance in Rust. The i3-14100F is particularly notable as a lower-core-count alternative that still matches closely, suggesting that Rust's CPU demands are not extreme at 1080p Low. For the AMD Radeon RX 570, the nearest rivals are the AMD Radeon RX 6800M at 28874 (0.4% lower), the AMD Radeon R9 M295X at 28580 (0.7% higher), the AMD Radeon RX 470 at 28996 (0.8% lower), and the NVIDIA Quadro RTX 8000 at 28421 (1.2% higher). The RX 470 is essentially the same GPU with a slight clock difference, so it would deliver nearly identical FPS. The R9 M295X and Quadro RTX 8000 are interesting outliers: they score within 1.2% despite being from different eras and market segments, indicating that the RX 570's performance level is a common baseline. A user with any of these GPUs paired with a similar CPU would see the same 1080p Low playability and the same inability to handle 1440p or 4K.

Best Settings per Resolution

The data provides a clear answer for each resolution. At 1920x1080, the most demanding preset that stays at or above 60 FPS is Low, with an average of 63.4 FPS. Medium, High, and Ultra all fall below the threshold, so Low is the only viable choice. At 2560x1440, there is no preset that reaches 60 FPS; the closest is Low at 46.1 FPS, which is 13.9 FPS short. The best the user can do is accept 46.1 FPS or lower the resolution. At 3840x2160, no preset is playable, and the best result is Low at 29.4 FPS. For users who prioritize frame rate over visuals, the recommendation is unambiguous: 1080p Low is the only configuration that meets the playable threshold. Any attempt to increase settings or resolution will result in a sub-60 FPS experience, with the penalty being most severe at 4K where even Low settings deliver less than half the required frame rate. The margin at 1080p Low is thin, so users with demanding scenes may experience drops below 60 FPS, but the average is above the line.

How This Combo Ranks

In the database of tested combinations for Rust, this pairing ranks 3547 out of 3723 combos. This places it in the bottom 5.2% of all configurations, which is a poor showing. The rank reflects the overall performance across all resolutions and settings, and the data supports this low position: the combo only achieves playable frame rates at 1080p Low, while most other tested systems likely clear 60 FPS at higher settings or resolutions. The GPU's age and 4 GB memory capacity are likely the main contributors to this low rank, as the CPU's percentile (72nd among all CPUs) is much stronger than the GPU's (74th among all GPUs), but the combination underperforms in Rust specifically. The rank indicates that this system is at the low end of what can run the game at all, and users should not expect any headroom for future updates or more demanding community servers. The data suggests that this build is a legacy configuration that can handle Rust only in its most basic form, and it sits far below the median tested combo in the database.
