Rust

The Intel Core i5-12400F paired with the AMD Radeon RX 580 delivers a narrow band of playable performance in Rust, and only at the most modest settings. The recorded data shows a system that is fundamentally limited by the GPU at higher resolutions and quality presets, though the CPU has enough headroom to push respectable frame rates when the graphical load is reduced.

Measured FPS Breakdown

The benchmark results for this combination in Rust are recorded across three resolutions and four settings presets, with the strongest performance appearing at 1080p with Low settings.

At 1920x1080, the average frame rates are as follows: Low settings produce an average of 76.2 FPS, Medium settings drop to 49.2 FPS, High settings yield 43.9 FPS, and Ultra settings fall to 32.1 FPS. The jump from Low to Medium represents a significant 27 FPS loss, indicating that the RX 580's memory bandwidth and compute resources are heavily taxed as soon as texture quality and shadow details increase.

At 2560x1440, the averages decline across the board. Low settings manage 52.5 FPS, which is still below the 60 FPS playable threshold. Medium settings produce 32.0 FPS, High settings yield 32.1 FPS, and Ultra settings drop to 22.0 FPS. The near-identical scores between Medium and High at this resolution suggest a bottleneck that prevents further scaling, likely the GPU's pixel fill rate or shader throughput.

At 3840x2160, the results are largely unplayable. Low settings average 31.6 FPS, Medium settings drop to 18.6 FPS, High settings manage 14.4 FPS, and Ultra settings fall to 11.7 FPS. The gap between Low and Medium at 4K is 13 FPS, which is proportionally larger than the gap at 1080p, reinforcing that the RX 580's 256-bit memory interface and 8 GB GDDR5 buffer are overwhelmed by 4K rendering workloads.

Min and max frame rate values are not recorded in the database, so the analysis relies solely on average FPS. The absence of min FPS data means stutter behavior cannot be quantified, but the average values alone indicate that only the 1080p Low preset clears the 60 FPS threshold.

CPU and GPU Roles

The data reveals a clear division of labor between the Intel Core i5-12400F and the AMD Radeon RX 580 across resolutions. At 1080p, the CPU's single-thread performance becomes relevant. The i5-12400F scores 909 in 3dmark_single_thread and 1680 in cinebench_r23_singlecore, which are strong numbers for a desktop part from the Core 12th Gen lineup. This allows the system to reach 76.2 FPS at Low settings, where the GPU is not the primary constraint.

However, as resolution increases, the GPU's role dominates. The RX 580's average benchmark score of 12928 places it in the 53rd percentile among all GPUs, and its 6.175 TFLOPS FP32 throughput is insufficient for high-resolution rendering. The scaling from 1080p Low to 1440p Low shows a drop from 76.2 to 52.5 FPS, a 31% reduction. Scaling from 1080p Low to 4K Low shows a drop to 31.6 FPS, a 59% reduction. These percentages align with the GPU being the limiting factor, as pixel count increases disproportionately impact the RX 580's fill rate.

At Medium and High presets, the CPU's role diminishes further. The 1440p Medium average of 32.0 FPS is nearly identical to the 1440p High average of 32.1 FPS, and both are far below the 1080p Medium score of 49.2 FPS. This pattern indicates that the GPU reaches a saturation point around 32 FPS at 1440p regardless of whether Medium or High settings are applied. The CPU, with 6 cores and 12 threads, is not the bottleneck here; the i5-12400F's multicore score of 12380 in cinebench_r23 is ample for Rust's typical thread usage. Instead, the RX 580's 32 ROPs and 144 TMUs cannot keep pace with the increased fragment work at higher resolutions.

At 4K, the GPU is almost entirely responsible for the low scores. The 14.4 FPS High average and 11.7 FPS Ultra average are consistent with a GPU that is rendering nearly four times the pixels of 1080p while maintaining the same texture complexity. The CPU's contribution is negligible at this point, as even the Low preset at 4K (31.6 FPS) is lower than the 1440p High preset (32.1 FPS), proving that resolution scaling, not CPU capability, dictates performance.

All four alternatives would produce similar average FPS in Rust at the same settings, though driver-level differences in Rust's OpenGL or Vulkan paths could cause minor variations not captured in the aggregate scores.

How This Combo Ranks

The combination of the Intel Core i5-12400F and AMD Radeon RX 580 ranks 3389 out of 3723 tested combos in the database for Rust. This places the system in the bottom 9% of all configurations, which is consistent with the GPU's age and the game's demanding rendering pipeline. The rank reflects that most modern gaming PCs, even those with mid-range GPUs from later generations, outperform this pairing. The RX 580's percentile of 53 among all GPUs and the i5-12400F's percentile of 73 among all CPUs do not translate into a competitive gaming result for Rust, because the game stresses the GPU heavily at higher settings.

The low rank is driven primarily by the 4K and 1440p results, where the RX 580 falls far below playable levels. Even at 1080p, only the Low preset clears 60 FPS, and the Medium preset at 49.2 FPS is 18% below the threshold. The CPU's strong relative standing (73rd percentile) does not compensate for the GPU's mid-pack performance, as Rust's frame rate scales more with GPU throughput than CPU single-thread speed in the recorded data.

The Verdict

This PC can run Rust, but only under strict conditions. The database's verdict by resolution states that 1920x1080 with Low settings is the sole playable configuration, achieving an average of 76.2 FPS. At 2560x1440, no settings preset reaches 60 FPS; the best case is Low at 52.5 FPS, which is 12.5% below the threshold. At 3840x2160, all presets are unplayable, with the highest average being 31.6 FPS at Low.

For a player targeting 1080p gaming, this combination is viable for Rust at the lowest quality settings. The 76.2 FPS average provides a smooth experience in most scenarios, though the lack of min FPS data means occasional dips cannot be ruled out. For 1440p or 4K, the system is not suitable, and users would need to lower resolution or accept sub-60 FPS gameplay. The i5-12400F has enough headroom for future GPU upgrades, but the RX 580 is the limiting factor in this pairing, and its 8 GB VRAM and 185 W TDP reflect its age. As a 1080p Low-settings machine, it works; as anything more, it falls short.
