Rust

The Intel Core i5-12400 and AMD Radeon RX 7700 XT combination delivers a playable experience in Rust, but the data reveals a clear hierarchy: this is a 1080p and 1440p pairing that struggles to maintain smooth frame rates at 4K. The measured results show a severe performance cliff as resolution increases, indicating that the GPU becomes the primary bottleneck at higher pixel counts. At 4K Ultra, the combo averages just 33.4 FPS, a figure that falls well below the threshold for comfortable competitive play, while the same settings at 1080p yield 81.7 FPS.

Resolution Scaling

The frame rate drop from 1080p to 4K is dramatic and tells a clear story about system balance. At Low settings, the combo produces 190.2 FPS at 1920x1080 but falls to 77.6 FPS at 3840x2160—a reduction of 112.6 FPS, or roughly 59% of the 1080p performance. The scaling is even more punishing at Ultra settings: 81.7 FPS at 1080p collapses to 33.4 FPS at 4K, a loss of 48.3 FPS. This pattern strongly suggests that the RX 7700 XT's 12 GB of GDDR6 memory and 192-bit bus are being saturated at higher resolutions, while the CPU's six cores have ample headroom at 4K.

The intermediate resolution confirms this trend. At 2560x1440, the combo delivers 130 FPS on Low and 55.3 FPS on Ultra. The gap between Low and Ultra at 1440p is 74.7 FPS, whereas at 1080p that same gap is 108.5 FPS. This narrowing delta as resolution increases is a classic sign of GPU limitation—the CPU can feed frames quickly at 1080p, but the GPU cannot keep pace when pixel count rises. The data indicates that 1440p is the practical ceiling for this pairing, with 4K reserved only for the lowest settings if playable frame rates are required.

How This Combo Ranks

Within the benchmark database, this specific CPU+GPU pairing ranks 683rd out of 1717 tested combinations for Rust. That places it in the 60th percentile of all combos, which is a solidly mid-pack result. The ranking reflects a balanced pairing where neither component is severely over- or under-powered for the other. The RX 7700 XT alone sits in the 73rd percentile among all GPUs, while the i5-12400 ranks in the 77th percentile among all CPUs. This near-parity in percentile positioning suggests the two components are well-matched for general workloads, though Rust's specific demands skew the in-game result slightly lower.

The combo's rank of 683 out of 1717 means there are 1,034 tested combinations that perform worse in Rust, but also 682 that perform better. This is not a top-tier configuration, but it is far from a weak one. The data shows that the pairing is more than capable of delivering high refresh rates at 1080p on medium-to-high settings, which aligns with its mid-pack status. The ranking does not account for price or efficiency, only raw measured frame rates in this specific title.

GPU Role

The AMD Radeon RX 7700 XT is the dominant factor in determining Rust's performance at higher resolutions. Built on the 5 nm process with the Navi 32 chip, this GPU features 3,456 shading units, 216 texture mapping units, and 96 raster output pipelines. Its boost clock reaches 2544 MHz, with a game clock of 2171 MHz. The 12 GB of GDDR6 memory operates across a 192-bit bus, delivering 432.0 GB/s of bandwidth. These specs translate to a pixel rate of 244.2 GPixel/s and a texture rate of 549.5 GTexel/s.

Benchmark results show the GPU achieves a PassMark G3D score of 22547 and an average benchmark score of 30097, placing it in the 73rd percentile of all GPUs. Its closest rival is the NVIDIA GeForce RTX 5060, which scores 30109—a negligible 0% difference. The RX 7700 XT also outperforms the AMD Radeon RX 570 by 0.2% and the NVIDIA Tesla M60 by 0.4%, while trailing the RTX 5070 Mobile by 0.6%. In Rust specifically, the GPU's 12 GB VRAM capacity is sufficient for 1080p and 1440p at all settings, but the 4K Ultra result of 33.4 FPS suggests either VRAM capacity or memory bandwidth becomes a limiting factor at that resolution.

Settings Recommendations

Based on the measured FPS data, the High preset offers the best balance of visual quality and performance for this combo. At 1920x1080, High delivers 109.1 FPS, which is smooth for most gameplay scenarios. At 2560x1440, High produces 75.6 FPS, still comfortably playable. The Medium preset provides higher frame rates—128.5 FPS at 1080p and 85.7 FPS at 1440p—but the incremental gain over High is modest relative to the visual downgrade. Low settings are only recommended for competitive play at 1440p, where 130 FPS is achievable, or for attempting 4K at 77.6 FPS.

Ultra settings are not recommended for this pairing. Even at 1080p, Ultra yields only 81.7 FPS, which is 27.4 FPS slower than High. At 1440p, Ultra drops to 55.3 FPS, and at 4K it becomes unplayable at 33.4 FPS. The performance cost of Ultra is disproportionate to its visual benefit in Rust, and the data clearly shows that High is the sweet spot for this hardware combination.

Measured FPS Breakdown

At 1920x1080, the combo delivers 190.2 FPS on Low, 128.5 FPS on Medium, 109.1 FPS on High, and 81.7 FPS on Ultra. The scaling from Low to Ultra is steep, with Ultra delivering only 42.9% of the Low settings frame rate. At 2560x1440, results are 130 FPS on Low, 85.7 FPS on Medium, 75.6 FPS on High, and 55.3 FPS on Ultra. The drop from 1080p to 1440p is consistent across settings, averaging about 31.5% fewer frames. At 3840x2160, the results are 77.6 FPS on Low, 51.9 FPS on Medium, 45 FPS on High, and 33.4 FPS on Ultra. The 4K Low result is the only 4K configuration that approaches playability, while 4K Ultra is clearly not viable.

CPU Role

The Intel Core i5-12400 provides the processing foundation for this combo. It features 6 cores and 12 threads, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Built on the 10 nm Alder Lake architecture, it has 18 MB of shared L3 cache and supports both DDR4 and DDR5 memory. Its benchmark results are strong: Cinebench R23 multicore scores 15935 and single-core scores 2249, while PassMark multithread reaches 18747 and single-thread 3456. The CPU ranks in the 77th percentile of all processors, with an average benchmark score of 19850.

Its nearest rival is the Intel Core i7-9700 with a score of 19831, which is just 0.1% different, and the Intel Core i7-8700 at 19894, which is 0.2% ahead. The AMD Ryzen Threadripper PRO 5995WX scores 19928 (0.4% ahead), and the Intel Core i5-11600K scores 19771 (0.4% behind). In Rust, the CPU's single-thread performance is critical for game logic and physics, and the data shows that at 1080p Low settings, the combo achieves 190.2 FPS, indicating the CPU can feed frames quickly. However, at 4K Ultra, the frame rate falls to 33.4 FPS, and since the CPU's capability does not diminish with resolution, this confirms the GPU is the constraining factor at higher pixel counts. The i5-12400's 6 cores are sufficient for Rust's demands, as evidenced by the strong 1080p results, and the CPU does not appear to limit performance in any of the measured configurations.
