Rust

The Intel Core i5-12400 paired with the AMD Radeon RX 7600 presents a balanced mid-range setup for Rust, but the data shows a system that is decisively limited by the graphics card at higher resolutions. This analysis breaks down the measured performance across the three primary resolutions and four quality presets.

Resolution Scaling

The performance drop from 1080p to 4K is steep and consistent, revealing a GPU-bound scenario at higher resolutions. At Low settings, the average frame rate falls from 140.3 FPS at 1920x1080 to 94.3 FPS at 2560x1440, a reduction of 46 FPS. Moving to 4K at Low settings yields 57.8 FPS, which is less than half of the 1080p result. This steep decline indicates that the RX 7600's rendering capabilities are the primary bottleneck as pixel count increases.

The scaling pattern is similar across other presets. At High settings, the system delivers 79.9 FPS at 1080p, drops to 51.4 FPS at 1440p, and further falls to 33.4 FPS at 4K. The Ultra preset shows the most dramatic falloff: 62.3 FPS at 1080p, 40.9 FPS at 1440p, and only 21.7 FPS at 4K. These numbers suggest that the CPU has sufficient headroom at 1080p, but the GPU's 8 GB memory and 128-bit bus become increasingly strained as resolution climbs. The gap between Low and Ultra at each resolution is substantial—at 1080p the difference is 78 FPS, at 1440p it is 53.4 FPS, and at 4K it is 36.1 FPS.

CPU Role

The Intel Core i5-12400 is a 6-core, 12-thread processor from the Alder Lake architecture, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its benchmark scores position it as a competent gaming CPU; the Cinebench R23 multi-core score of 15935 and single-core score of 2249 indicate solid throughput for a mid-range part. The processor sits at the 77th percentile against all CPUs, with an average benchmark score of 19850.

Its nearest rivals in average score include the Intel Core i7-9700 (19831, a 0.1% delta) and the Core i7-8700 (19894, -0.2% delta). This shows the i5-12400 trades blows with older i7 parts, meaning its 12 threads and modern architecture are enough to avoid being the limiting factor in Rust at most settings. The data suggests that at 1080p Low, where the GPU produces 140.3 FPS, the CPU is likely still keeping pace, but the frame rate ceiling is more likely dictated by the graphics card than the processor. The L3 cache of 18 MB shared across the cores helps with the game's world streaming, though specific in-game CPU utilization is not provided in the measured data.

How This Combo Ranks

This specific combination of the Core i5-12400 and Radeon RX 7600 ranks 1199 out of 1717 tested combos for Rust. That places it in the lower third of all system pairings, which might seem surprising given the individual component scores. However, this rank reflects the overall average performance across all tested settings and resolutions, not just the best-case 1080p results.

The rank indicates that while this combo is far from the top, it is also not at the bottom of the barrel. The i5-12400's CPU percentile of 77 is strong, but the RX 7600's GPU percentile of 63 is more modest. This imbalance means the combo's overall standing is dragged down by the GPU's mid-tier position. Compared to other combos that might pair the same CPU with a higher-end GPU, or a lower-tier CPU with a stronger GPU, this pairing lands in the middle of the pack. The data implies that for users prioritizing high refresh rate 1080p gaming, this rank might be acceptable, but for 4K enthusiasts, the combo will likely struggle to compete with higher-ranked configurations.

Measured FPS Breakdown

At 1920x1080, the measured results are as follows: Low settings produce an average of 140.3 FPS, Medium yields 92.6 FPS, High delivers 79.9 FPS, and Ultra drops to 62.3 FPS. These numbers show that 1080p is the sweet spot for this hardware, with even Ultra settings remaining playable.

At 2560x1440, the averages are 94.3 FPS for Low, 61.7 FPS for Medium, 51.4 FPS for High, and 40.9 FPS for Ultra. The drop from Medium to High at 1440p is only 10.3 FPS, suggesting that the visual uplift from Medium to High is relatively cheap in performance terms. However, the jump from High to Ultra costs 10.5 FPS, which is a steeper penalty for marginal visual gains.

At 3840x2160, the results are 57.8 FPS for Low, 39.5 FPS for Medium, 33.4 FPS for High, and 21.7 FPS for Ultra. The 4K Ultra result is the only average below 30 FPS in the entire dataset, making it the single most demanding configuration tested. The difference between 1080p Low and 4K Low is 82.5 FPS, highlighting the massive impact of resolution on this GPU.

GPU Role

The AMD Radeon RX 7600 is built on the RDNA 3.0 architecture with a Navi 33 chip, manufactured on a 6 nm process. It features 2048 shading units, 128 TMUs, and 64 ROPs, with a boost clock of 2655 MHz. The 8 GB of GDDR6 memory on a 128-bit bus provides 288.0 GB/s of bandwidth. The GPU's benchmark scores show a PassMark G3D score of 16634 and a 3DMark Steel Nomad DX12 score of 2310, placing it at the 63rd percentile against all GPUs.

Its nearest rival in average score is the AMD Radeon RX 7600 XT (20146, a 0.6% delta), which is notably close, meaning the RX 7600 is nearly matching a higher-tier sibling in synthetic tests. The gap to the NVIDIA GeForce RTX 3070 Mobile (20534, -1.3% delta) is also small. This data suggests the RX 7600 is a solid performer for its class, but the 8 GB VRAM capacity is a potential limitation in Rust at 4K, where texture streaming can be heavy. The measured FPS at 4K Ultra (21.7 FPS) confirms that the GPU is overwhelmed, likely due to both memory bandwidth and compute limitations.

Settings Recommendations

For the best balance of visual quality and frame rate, the data points to the High preset at 1920x1080 as the optimal choice. It delivers 79.9 FPS, which is smooth for most players, while providing a significant visual upgrade over Medium (92.6 FPS) or Low (140.3 FPS). The jump from High to Ultra at 1080p only costs 17.6 FPS (from 79.9 to 62.3), but the visual difference in Rust is often subtle, making Ultra a less efficient choice unless frame rate is not a priority.

At 2560x1440, the Medium preset (61.7 FPS) is the recommended starting point, as it remains above the 60 FPS threshold and offers better visuals than Low (94.3 FPS). High at 1440p (51.4 FPS) is playable but may feel less responsive in fast-paced combat scenarios. For 4K gaming, Low settings (57.8 FPS) are the only viable option for a playable experience; Medium (39.5 FPS) and High (33.4 FPS) are borderline, while Ultra (21.7 FPS) is not recommended for serious play. The data strongly suggests that this combo is best suited for 1080p gaming, where it can handle all presets with acceptable performance, and that users should avoid 4K Ultra unless they are willing to accept a slideshow-like frame rate.
