Rust

The Intel Core i5-12400 and NVIDIA GeForce GTX 1660 Ti combination delivers playable frame rates in Rust, but only under specific settings and resolution constraints. The data shows a system that is heavily GPU-limited at higher resolutions, with the CPU demonstrating sufficient headroom to push much higher frame rates when the graphical load is reduced. The measured results indicate that this combo is best suited for 1080p gaming, where it can achieve a smooth experience on lower presets, while 4K remains firmly out of reach for competitive play.

Resolution Scaling

Resolution scaling in Rust reveals a stark performance cliff for this hardware pairing. Moving from 1920x1080 to 2560x1440 on the Low preset drops the average frame rate from 106 FPS to 72.1 FPS, a reduction of 33.9 FPS. The scaling continues aggressively at 4K, where the Low preset manages only 44.8 FPS. This pattern of diminishing returns as resolution increases points directly to the GPU as the primary bottleneck, as the workload becomes increasingly pixel-bound.

The frame rate collapse is most dramatic on the Ultra preset. At 1080p, the combo produces 45 FPS, which falls to 33 FPS at 1440p and plummets to 19.3 FPS at 4K. The High preset follows a similar trajectory, dropping from 62.2 FPS at 1080p to 41.7 FPS at 1440p and finally to 23.3 FPS at 4K. These numbers indicate that the GTX 1660 Ti's 6 GB VRAM and 192-bit memory bus are simply overwhelmed by the pixel throughput required at higher resolutions, especially when texture and shading complexity increase.

The scaling behavior suggests that the CPU is not the limiting factor in this game. The i5-12400's six cores and twelve threads provide enough processing power to feed the GPU at lower resolutions, as evidenced by the 106 FPS result at 1080p Low. If the CPU were the constraint, we would expect to see a plateau in frame rates regardless of resolution changes, but the data shows a consistent and substantial drop with each step up in resolution, confirming that the GTX 1660 Ti is the performance ceiling.

CPU Role

The Intel Core i5-12400 brings a solid foundation for Rust, with six cores and twelve threads operating at a base clock of 2.50 GHz and a boost clock of 4.40 GHz. The processor's benchmark results show strong multi-threaded capability, with a Cinebench R23 multi-core score of 15935 and a single-core score of 2249. These figures place the CPU in the 77th percentile against all CPUs, indicating it has ample headroom for gaming workloads.

In the context of Rust's measured FPS, the CPU appears to be performing its role effectively without becoming a bottleneck. The benchmark data shows that at 1080p Low, the system reaches 106 FPS, a figure that is likely near the practical limit for this GPU at that settings level. The processor's 18 MB of shared L3 cache and support for DDR4 and DDR5 memory provide sufficient bandwidth for game logic and world simulation, which are CPU-intensive aspects of survival games like Rust.

The i5-12400's nearest rivals in synthetic benchmarks include the Intel Core i7-9700 with an average score of 19831, a delta of 0.1 percent, and the Intel Core i7-8700 at 19894, a delta of -0.2 percent. This places the i5-12400 in a performance tier that is effectively equivalent to these older i7 parts, suggesting that CPU performance is not a weakness in this combo. The processor's 65 W TDP and Alder Lake architecture contribute to efficient operation, but the measured FPS data indicates that the GPU is the component that dictates overall frame rates.

GPU Role

The NVIDIA GeForce GTX 1660 Ti is the decisive factor in this combo's Rust performance. With 6 GB of GDDR6 memory, a 192-bit bus, and 288.0 GB/s of bandwidth, the card has enough memory capacity for most game assets at 1080p, but struggles as resolution increases. The GPU's base clock of 1500 MHz and boost clock of 1770 MHz, combined with 1536 shading units, deliver a measured performance that places it in the 55th percentile against all GPUs.

The GPU's benchmark results, including a Passmark G3D score of 12871, show it to be a mid-range performer. Its nearest rivals include the AMD Radeon RX 570X with an average score of 13871 (0.4 percent delta) and the NVIDIA GeForce GTX 680 at 13812 (0.8 percent delta). This positioning explains the observed frame rates in Rust: the card can handle the game at 1080p with reasonable settings, but the 4K Ultra result of 19.3 FPS is clearly unplayable, and even 1440p High at 41.7 FPS falls short of smooth gameplay standards.

The GPU's 12 nm process node and Turing architecture, while dated, still provide DirectX 12 support, which Rust can utilize. However, the 6 GB VRAM capacity becomes a limiting factor at higher resolutions, likely causing texture swapping and reduced performance. The measured FPS data shows that the GTX 1660 Ti is the primary constraint in this system, as evidenced by the fact that reducing settings from Ultra to Low at any given resolution yields a substantial frame rate increase, whereas the CPU's capabilities remain underutilized.

Settings Recommendations

The measured FPS data provides clear guidance for optimal settings. At 1920x1080, the Low preset delivers 106 FPS, which is excellent for competitive play, while the Medium preset still achieves a respectable 72.7 FPS. The High preset at 62.2 FPS is playable, but the Ultra preset at 45 FPS introduces noticeable stutter in fast-paced scenarios. For the best balance of visual quality and performance at 1080p, the Medium preset is the recommended choice, as it provides a significant visual upgrade over Low while maintaining a frame rate well above the 60 FPS threshold.

At 2560x1440, the situation becomes more constrained. The Low preset achieves 72.1 FPS, which is playable, but the Medium preset drops to 50.3 FPS and High falls to 41.7 FPS. The data suggests that at 1440p, users should stick with the Low preset for competitive play, as the visual upgrade from Medium does not justify the substantial frame rate loss. The Ultra preset at 33 FPS is not recommended.

At 3840x2160, the results are clear: this combo is not suited for 4K gaming in Rust. Even the Low preset only manages 44.8 FPS, and the High preset at 23.3 FPS is unplayable. Users with a 4K monitor should plan to run the game at 1080p or 1440p with the Low or Medium presets, as the 4K Ultra result of 19.3 FPS is far below any acceptable threshold. The data indicates that the GPU's 6 GB VRAM and bandwidth are insufficient for 4K workloads in this title.

How This Combo Ranks

The Intel Core i5-12400 and NVIDIA GeForce GTX 1660 Ti combination ranks 1495 out of 1717 tested combos in Rust, placing it in the bottom 13 percent of all configurations. This ranking reflects the GPU's mid-range status and the game's demanding nature at higher settings. The combo's position suggests that while the CPU is capable, the GPU holds back overall performance, particularly at resolutions above 1080p.

The rank of 1495 out of 1717 indicates that a significant majority of tested combos outperform this pairing in Rust. This is consistent with the GPU's 55th percentile ranking and the fact that the GTX 1660 Ti is nearing end-of-life status. The CPU's 77th percentile ranking does little to compensate for the GPU's limitations in this game, as the measured FPS data shows the GPU to be the bottleneck at all resolutions above 1080p Low.

For context, the combo's rank suggests that users seeking higher frame rates in Rust would need to upgrade the GPU first, as the i5-12400 provides sufficient processing power for the game's CPU demands. The data shows that the combo is functional for 1080p gaming with adjusted settings, but it does not compete with higher-end configurations that can maintain 60 FPS at higher resolutions and presets.
