Rust

The Intel Core i5-12400 and NVIDIA GeForce RTX 3060 Ti combination delivers a revealing performance profile in Rust, one that shifts character dramatically depending on the resolution and quality preset selected. The measured data shows a system that can dominate at 1080p but struggles to maintain fluidity at 4K, pointing to a clear division of labor between the processor and graphics card. This analysis breaks down the measured frames per second to understand where the bottleneck lies and what the experience truly feels like across the board.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and tells a clear story about what limits this combo in Rust. At 1080p with Low settings, the system produces 138.8 FPS, but that number collapses to 57.9 FPS at 4K with the same preset. That is a 58% reduction in frame rate when moving from 1920x1080 to 3840x2160. The pattern holds across all settings: High goes from 78.5 FPS at 1080p to 55.9 FPS at 1440p and finally 34 FPS at 4K. Ultra settings are even more punishing, starting at 56.5 FPS at 1080p and falling to 23.4 FPS at 4K.

This scaling behavior indicates that at 1080p, the CPU is doing a significant amount of the heavy lifting, keeping frame rates high even when the GPU has less work to do. As resolution climbs, the pixel count increases and the GPU becomes the primary constraint. The data shows a non-linear drop: the gap between 1080p and 1440p is larger than the gap between 1440p and 4K for most settings. For instance, Low settings drop from 138.8 FPS at 1080p to 95.8 FPS at 1440p (a 43 FPS loss), but only drop another 37.9 FPS when moving to 4K. This suggests that while the RTX 3060 Ti is increasingly taxed at higher resolutions, the processor still has headroom to push frames at lower pixel counts.

The results imply that this combination is best suited for 1080p or 1440p gaming in Rust. At 4K, the GPU simply cannot keep up, and even the Medium preset, which offers a balance of quality, only manages 38.9 FPS. The Ultra preset at 4K is nearly unplayable at 23.4 FPS. For a game like Rust, where player interactions and base building demand responsiveness, the 4K experience would feel sluggish regardless of the visual fidelity.

CPU Role

The Intel Core i5-12400 brings six cores and twelve threads to the table, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. In the broader CPU landscape, it sits in the 77th percentile among all processors, with an average benchmark score of 19850. Its nearest rivals include the Intel Core i7-9700, which scores nearly identically (19831, a 0.1% difference), and the Intel Core i7-8700 (19894, -0.2%). This places the i5-12400 in a strong position for gaming, where single-thread performance often matters more than raw multi-core grunt.

In Rust, the CPU's influence is most visible at 1080p Low settings, where the system achieves 138.8 FPS. That frame rate is high enough to suggest the processor is not the limiting factor at that resolution. The 3DMark single-thread score of 910 and the Cinebench R23 single-core score of 2249 indicate solid per-core performance, which helps in a game that often relies on a few heavily loaded threads. The L3 cache of 18 MB shared across the six cores also aids in keeping frequently accessed data close at hand, reducing latency in a world where terrain and entity positions change constantly.

However, the CPU's role becomes less dominant as resolution increases. At 4K Ultra, the frame rate drops to 23.4 FPS, a number so low that no amount of CPU headroom can compensate. The data suggests that the i5-12400 is capable of feeding the RTX 3060 Ti at 1080p and 1440p, but the GPU's rendering limits take over at 4K. The 3DMark 16-thread score of 5873 and the max-thread score of 5890 show that multi-threaded workloads are handled well, but Rust's engine may not fully utilize all twelve threads, leaving the boost clock of 4.40 GHz as the more critical specification for frame pacing.

GPU Role

The NVIDIA GeForce RTX 3060 Ti is an Ampere-based card with 8 GB of GDDR6 memory on a 256-bit bus, delivering 448.0 GB/s of bandwidth. Its boost clock is 1665 MHz, and it features 4864 shading units. In the GPU hierarchy, it ranks in the 69th percentile of all graphics cards, with an average benchmark score of 25120. Its nearest rivals are interesting: the AMD Radeon RX 6700M scores 25180 (-0.2%), the RX 6600 scores 25235 (-0.5%), and the Radeon 890M scores 25246 (-0.5%). This shows the RTX 3060 Ti is slightly below these competitors in aggregate benchmarks, but the margin is thin.

In Rust, the GPU's memory capacity and bandwidth become critical at higher resolutions. The 8 GB VRAM is sufficient for 1080p and 1440p, but at 4K Ultra, the game likely pushes against the memory limit, contributing to the 23.4 FPS result. The texture rate of 253.1 GTexel/s and the pixel rate of 133.2 GPixel/s are solid for a mid-range card, but they cannot overcome the sheer pixel count at 3840x2160. The data shows that at 4K, the difference between Low (57.9 FPS) and High (34 FPS) is a 24 FPS gap, indicating that the GPU is the primary determinant of performance at this resolution.

The RTX 3060 Ti also supports DirectX 12 Ultimate, which Rust can leverage for modern rendering features. However, the measured FPS at 4K suggests that the card is not powerful enough to maintain high frame rates with maxed-out settings. The 1080p Ultra result of 56.5 FPS is playable but not smooth for a competitive survival game, while the 1440p Medium result of 64.6 FPS offers a better balance. The GPU's 200 W TDP and the 550 W suggested PSU indicate a power-hungry card, but the performance data is what matters most here: this is a 1080p and 1440p card for Rust, not a 4K solution.

FAQ

Q: Is the CPU or GPU the bottleneck at 1080p?

A: At 1080p Low, the system hits 138.8 FPS, which is high enough to suggest the CPU is not the limiting factor. The GPU is likely the constraint even at this resolution, as the frame rate scales down significantly when settings are increased to Ultra (56.5 FPS).

Q: What is the combo's ranking among tested systems?

A: This combination ranks 1151 out of 1717 tested combos in Rust, placing it in the lower third of all systems tested. This suggests that while it performs adequately at lower resolutions, it is not a top-tier setup for this game.

Q: Does the CPU's single-thread performance matter for Rust?

A: The i5-12400 has a 3DMark single-thread score of 910 and a Cinebench R23 single-core score of 2249. These scores indicate strong per-core performance, which is important for Rust's engine, but the data shows that the GPU becomes the bottleneck as resolution increases.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four quality settings, providing a complete picture of the combo's capabilities. At 1920x1080, the results are: Low 138.8 FPS, Medium 94.5 FPS, High 78.5 FPS, and Ultra 56.5 FPS. The jump from Low to Medium costs 44.3 FPS, while the jump from High to Ultra costs 22 FPS, showing diminishing returns as quality increases.

At 2560x1440, the results are: Low 95.8 FPS, Medium 64.6 FPS, High 55.9 FPS, and Ultra 43 FPS. The drop from 1080p to 1440p is consistent across settings, averaging around 30-40% fewer frames. Low settings remain playable at 95.8 FPS, but Ultra drops to 43 FPS, which is below the 60 FPS threshold for smooth gameplay.

At 3840x2160, the results are: Low 57.9 FPS, Medium 38.9 FPS, High 34 FPS, and Ultra 23.4 FPS. Only Low settings achieve above 50 FPS, and even that is marginal. The step from Low to Medium costs 19 FPS, while the step from High to Ultra costs 10.6 FPS, indicating that the GPU is running out of headroom at this resolution. The data clearly shows that 4K is not a viable option for this combo unless the player accepts low visual quality and moderate frame rates.

Settings Recommendations

The measured rows suggest that the best experience for this combo is at 2560x1440 with Medium settings, which achieves 64.6 FPS. This balances visual quality with smoothness, staying above the 60 FPS mark that is often considered the minimum for a responsive game. At 1080p, Medium (94.5 FPS) or High (78.5 FPS) are both excellent options, with High offering better visuals at a still-playable frame rate.

For players who prioritize frame rate above all, 1080p Low at 138.8 FPS is the clear winner, but the visual sacrifice is substantial. At 4K, the data shows that only Low settings (57.9 FPS) are worth considering, and even then, the experience is mediocre. The Ultra preset is not recommended at any resolution, as it yields 56.5 FPS at 1080p, 43 FPS at 1440p, and 23.4 FPS at 4K, all of which are below the threshold for smooth gameplay. The sweet spot lies in Medium or High settings at 1080p or 1440p, where the RTX 3060 Ti's 8 GB VRAM and 448.0 GB/s bandwidth are sufficient to maintain a fluid experience.

How This Combo Ranks

In the database of tested combos for Rust, this configuration ranks 1151 out of 1717, placing it in the lower third of all systems. This ranking reflects the fact that Rust is a demanding game, especially at higher resolutions and settings. The CPU's performance is solid, with an average benchmark score of 19850, which is nearly identical to its nearest rival, the Intel Core i7-9700 (19831, 0.1% difference). However, the GPU's average benchmark score of 25120 is marginally below its closest competitors, such as the AMD Radeon RX 6700M (25180, -0.2%) and the RX 6600 (25235, -0.5%).

The ranking of 1151 out of 1717 suggests that many other combos outperform this one in Rust, likely due to more powerful GPUs or newer CPU architectures. The data shows that the i5-12400 and RTX 3060 Ti can handle 1080p and 1440p well, but they fall behind when pushed to 4K or Ultra settings. This is not a top-tier combo for Rust, but it is a capable mid-range option that delivers playable frame rates at lower resolutions. The percentile rankings (77th for CPU, 69th for GPU) indicate that both components are above average in their respective categories, yet the combination does not translate to a top-tier gaming experience in Rust specifically.
