Rust

The Intel Core i5-12400F paired with the AMD Radeon RX 5700 XT delivers a playable but resolution-sensitive experience in Rust, with the data showing a clear shift from CPU-bound performance at 1080p to GPU-bound limitations at 4K. The measured frames per second (FPS) reveal that while the combo can push past 130 FPS at lower settings in Full HD, it falls below 60 FPS at 4K on anything above Low settings. This places the combination in the 1291st position out of 1717 tested combos for Rust, indicating that while it is not at the top of the charts, it remains a viable option for mainstream gaming at 1440p with adjusted settings.

Resolution Scaling

The FPS drop from 1080p to 4K is dramatic, illustrating the GPU's dominance in determining performance at higher resolutions. At Low settings, the average FPS falls from 133.4 at 1920x1080 to 94.9 at 2560x1440, a reduction of roughly 29%, and then to 58 at 3840x2160, a further 39% decline. This scaling pattern is typical of a system where the RX 5700 XT becomes the primary bottleneck as pixel count increases. The transition from 1440p to 4K is particularly steep, with the Low setting losing 36.9 FPS, versus a 38.5 FPS loss from 1080p to 1440p, showing that the GPU's 8 GB memory and 448.0 GB/s bandwidth are increasingly strained at 4K.

At High settings, the trend is even more pronounced. The average FPS drops from 79.8 at 1080p to 54.7 at 1440p, a 31% decrease, and then plunges to 31.9 at 4K, a 42% drop from 1440p. This indicates that the combination is heavily GPU-limited at 4K, with the Ultra preset being nearly unplayable at 21.5 FPS. The scaling data suggests that for a smoother experience, users should target 1440p, where the drop from 1080p is more manageable, or stick to 1080p for maximum frame rates. The CPU, with its 6 cores and 12 threads, appears sufficient to feed the GPU at lower resolutions, as evidenced by the 133.4 FPS result at 1080p Low, but it cannot compensate for the GPU's limitations at higher resolutions.

GPU Role

The AMD Radeon RX 5700 XT is the deciding factor in this combo's performance at higher resolutions. Its 8 GB of GDDR6 memory on a 256-bit bus provides 448.0 GB/s of bandwidth, which is sufficient for 1080p and 1440p gaming but becomes a limiting factor at 4K. The GPU's clock speeds, with a base of 1605 MHz and a boost of 1905 MHz, along with a game clock of 1755 MHz, contribute to its 9.754 TFLOPS of FP32 performance. These specifications allow the card to handle Rust's shading and texture work efficiently at 1080p, where it achieves 79.8 FPS on High, but the data shows a clear degradation as resolution increases.

The card's 2560 shading units and 160 texture mapping units help explain its strong 1080p performance, but its 64 ROPs become a bottleneck at 4K. This is reflected in the 4K results, where even Medium settings only produce 37.4 FPS, and Ultra drops to 21.5 FPS. The GPU's 68th percentile ranking among all GPUs, based on an average benchmark score of 24731, places it in the mid-range tier. In comparison to its nearest rivals, the RX 5700 XT performs nearly identically to the NVIDIA RTX A5000 Mobile, with a deltaPct of -0.1, and is 0.3% ahead of the Intel Arc A350M. This suggests that the GPU's performance in Rust is consistent with its general benchmark standing, with no unusual game-specific advantages or disadvantages.

CPU Role

The Intel Core i5-12400F provides a solid foundation for this combo, though its role diminishes at higher resolutions. With 6 cores and 12 threads, a base clock of 2.50 GHz, and a boost clock of 4.40 GHz, the CPU offers strong single-thread and multi-thread performance. Its Cinebench R23 scores of 2332 for single-core and 16518 for multi-core demonstrate its capability to handle Rust's simulation and physics workloads. The 77th percentile ranking among all CPUs, with an average benchmark score of 19221, shows it sits just above the midpoint of tested processors.

The CPU's nearest rivals show it is closely matched with the Intel Core i7-8700K, with a deltaPct of 0.1, and the Intel Core i5-1335U, with a deltaPct of 0.3. This indicates that the i5-12400F is competitive with older high-end parts, providing adequate processing power for Rust's server-side and client-side computations. At 1080p Low, the combo reaches 133.4 FPS, suggesting the CPU is not the primary bottleneck at this resolution. However, the 18 MB of shared L3 cache and dual-channel memory support (DDR4 and DDR5) are sufficient for the game's demands. The CPU's role becomes less critical at 4K, where the GPU's performance ceiling limits overall FPS, but it still prevents any CPU-induced frame drops, maintaining stable averages across all tested settings.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo's performance across three resolutions and four settings presets. At 1920x1080, the combo delivers its best results, with Low settings achieving 133.4 FPS, Medium at 89.3 FPS, High at 79.8 FPS, and Ultra at 58.1 FPS. This shows a clear progression where higher settings reduce frame rates, but even Ultra remains playable above 60 FPS.

Moving to 2560x1440, the frame rates drop significantly but remain mostly playable. Low settings produce 94.9 FPS, Medium 65.6 FPS, High 54.7 FPS, and Ultra 37.7 FPS. The drop from 1080p to 1440p at Low settings is 38.5 FPS, while at Ultra it is 20.4 FPS, indicating that the GPU's load increases more steeply at lower settings where the CPU can still keep up.

At 3840x2160, the combo struggles to maintain playable frame rates on higher presets. Low settings achieve 58 FPS, which is just at the edge of playability, but Medium drops to 37.4 FPS, High to 31.9 FPS, and Ultra to 21.5 FPS. The data shows that 4K is only viable with Low settings, and even then, the frame rate is marginal. The overall pattern indicates that the combo is best suited for 1080p and 1440p gaming, with 4K reserved for less demanding titles or lower presets.

How This Combo Ranks

In Rust, this combo ranks 1291st out of 1717 tested combinations, placing it in the lower-middle portion of the database. This ranking reflects the balance between the i5-12400F's strong CPU performance and the RX 5700 XT's mid-range GPU capabilities. The rank suggests that while the combo is not a top-tier performer, it is far from the bottom, offering a reasonable experience for most players.

The ranking is influenced by the GPU's 68th percentile standing and the CPU's 77th percentile standing. When combined, these components produce a system that excels at 1080p but falls behind at higher resolutions. The combo's performance in Rust is consistent with its overall benchmark averages, with no significant outliers. The rank of 1291 indicates that many other combinations offer better 4K performance, but for 1080p and 1440p gaming, this setup remains competitive. The data suggests that users with this combo should prioritize 1080p for high frame rates or 1440p for a balance between visual quality and performance.

Settings Recommendations

For the best experience with this combo, the data supports using the Low preset at 1920x1080, which delivers 133.4 FPS and ensures smooth gameplay in fast-paced scenarios. If visual fidelity is a priority, the High preset at 1080p offers 79.8 FPS, which is still above the 60 FPS threshold for most players. At 2560x1440, the Medium preset provides a good balance at 65.6 FPS, while the High preset drops to 54.7 FPS, which may be acceptable for slower-paced play.

Avoid the Ultra preset at all resolutions, as it reduces frame rates significantly, with 58.1 FPS at 1080p, 37.7 FPS at 1440p, and 21.5 FPS at 4K. For 4K, only the Low preset achieves a playable 58 FPS, but this compromises visual quality. The measured data suggests that the ideal settings are Low or Medium at 1440p for a high-refresh experience, or High at 1080p for better visuals without sacrificing too much performance. Users with this combo should adjust settings based on their monitor's resolution, prioritizing 1080p for competitive play and 1440p for immersive sessions.
