Rust

The Intel Core i5-12400 paired with the AMD Radeon RX 9070 delivers a wide spread of performance in Rust, ranging from a demanding 4K Ultra experience that dips below playable thresholds to a high-refresh-rate 1080p setup. The measured data shows a system where the GPU is the clear scaling factor at higher resolutions, while the CPU’s six cores and 12 threads provide a solid foundation for the game’s simulation-heavy workload. Benchmark results indicate that this combination is most at home in the 1440p and 1080p ranges, where it can push beyond 60 FPS even at the highest preset.

Measured FPS Breakdown

At 3840x2160 (4K), the data shows a clear progression tied to the graphics preset. On Low settings, the combo averages 85.2 FPS, which is a comfortable margin above the 60 FPS playable threshold. Moving to Medium drops the average to 60.8 FPS, just barely clearing the bar. High settings reduce the average to 51.2 FPS, and Ultra falls to 38.9 FPS. The gap between Low and Ultra is substantial, a 46.3 FPS difference, indicating that the RX 9070’s shading units and memory bandwidth are heavily taxed at this resolution, particularly with the higher preset demands.

The 2560x1440 (1440p) results show a much healthier spread of playable options. Low settings produce an average of 147.5 FPS, which is nearly 2.5 times the 60 FPS threshold. Medium follows at 96.6 FPS, and High at 85.1 FPS. Even Ultra, the most demanding preset, maintains an average of 63.2 FPS, which is above the playable line. The step from Low to Ultra here is 84.3 FPS, but the key takeaway is that every preset tested at this resolution remains viable for smooth gameplay.

At 1920x1080 (1080p), the combination truly stretches its legs. Low settings yield an average of 204.4 FPS, which is well into high-refresh-rate territory. Medium produces 141.4 FPS, and High delivers 119 FPS. Ultra remains strong at 93.9 FPS, still far above the 60 FPS threshold. The scaling from Low to Ultra is 110.5 FPS, showing that even at the highest settings, the system has significant headroom. The data suggests that at 1080p, the CPU’s performance becomes a more significant factor, as the GPU has enough power to render frames quickly but the overall output is capped by the processor’s ability to feed the game’s logic.

CPU and GPU Roles

The division of labor between the Intel Core i5-12400 and the AMD Radeon RX 9070 changes predictably as resolution and settings shift. At 4K, the GPU is the dominant constraint. The average FPS drops sharply from 85.2 on Low to 38.9 on Ultra, a 54% reduction, which is a classic sign of GPU-bound rendering where the RX 9070’s compute units and memory interface are saturated. The CPU, with its 6 cores and 12 threads, has enough headroom to keep up with the frame pacing at this resolution, as evidenced by the fact that even the lowest FPS value (38.9) is not limited by processor stalls.

At 1440p, the balance shifts. The scaling from Low (147.5 FPS) to Ultra (63.2 FPS) is still significant, but the fact that Ultra stays above 60 FPS indicates that the GPU is still doing the heavy lifting, yet the CPU is capable of feeding it consistently. The difference between 1440p Low and 1080p Low is 56.9 FPS, which is larger than the difference between 1440p Ultra and 1080p Ultra (30.7 FPS). This suggests that at lower presets, the GPU is less stressed, and the CPU’s role in processing game logic and draw calls becomes more apparent, but the i5-12400 handles it without becoming a bottleneck.

At 1080p, the CPU’s influence is most visible. The jump from Ultra (93.9 FPS) to Low (204.4 FPS) is massive, but the absolute numbers are high enough that neither component is a hard blocker. The data shows that the RX 9070 is capable of far more than 204 FPS at low settings, but the i5-12400’s single-thread performance (3dmark_single_thread score of 910) and multi-thread capabilities (cinebench_r23_multicore score of 15989) are what keep the average from going even higher. In short, the GPU is the primary scaling factor at 4K and 1440p, while the CPU becomes co-limiting at 1080p, though both parts perform admirably.

Similar Performance Alternatives

Looking at the nearest rivals for the CPU, the Intel Core i5-12400 sits very close to several other processors in terms of average benchmark score. The AMD EPYC 7643 scores 18697, which is a 0.1% difference from the i5-12400’s 18683. This is essentially a statistical tie, meaning that in Rust, a system with the EPYC 7643 would likely produce nearly identical frame rates at the same settings, assuming the GPU and memory are the same. The Intel Core i7-1355U is another close match, with a score of 18730 (0.3% higher), and the AMD Ryzen AI 5 330 at 18811 (0.7% higher). The Intel Core i3-14100F scores 18519, which is 0.9% lower, so it would be marginally slower in CPU-bound scenarios, but the difference is within the noise of typical gameplay.

For the GPU, the AMD Radeon RX 9070’s nearest rivals are a mix of older and mobile parts. The NVIDIA GeForce GTX TITAN Z scores 23736, which is 0.6% lower than the RX 9070’s 23877, so it would deliver almost the same FPS in Rust at the same settings. The AMD Radeon RX 6800S scores 24063, which is 0.8% higher, meaning it would be slightly faster on average, though the difference is minimal. The NVIDIA GeForce RTX 3080 Mobile scores 23628 (1.1% lower) and the RTX 2080 SUPER scores 24170 (1.2% higher). In practice, any of these GPUs paired with a comparable CPU would produce frame rates within a few percentage points of the measured values, meaning that a user with a GTX TITAN Z or an RTX 2080 SUPER would see nearly identical performance in Rust at 1440p and 1080p.

The Verdict

The data is clear: this PC can run Rust, and it does so comfortably at most resolutions and presets. At 1920x1080, every preset from Low to Ultra clears the 60 FPS threshold, with Ultra averaging 93.9 FPS. At 2560x1440, all four presets also stay above 60 FPS, with Ultra at 63.2 FPS. This makes 1440p the sweet spot for visual fidelity without sacrificing smoothness. At 3840x2160, the situation is more limited. Low (85.2 FPS) and Medium (60.8 FPS) are playable, but High (51.2 FPS) and Ultra (38.9 FPS) fall short of the 60 FPS target. The verdict by resolution confirms this: 4K users must stick to Medium or Low, while 1440p and 1080p users can max out the settings.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is Medium, with an average FPS of 60.8. This is a close call, but it clears the threshold. For those who prefer a larger margin, Low settings provide 85.2 FPS, but Medium offers the best balance of visual quality and performance that meets the playable standard.

At 2560x1440, Ultra settings are the best choice, averaging 63.2 FPS. This allows for the highest visual fidelity while still maintaining a playable frame rate. If you want more headroom, High settings at 85.1 FPS or Medium at 96.6 FPS are also excellent options, but Ultra is the clear winner for image quality.

At 1920x1080, Ultra settings again take the top spot, with an average of 93.9 FPS. This is more than 30 FPS above the 60 FPS threshold, providing a smooth experience with all visual features enabled. For high-refresh-rate monitors, Low settings at 204.4 FPS or Medium at 141.4 FPS are preferable, but for standard 60 Hz displays, Ultra is the recommended setting.

How This Combo Ranks

In the grand scheme of tested hardware combinations for Rust, the Intel Core i5-12400 with the AMD Radeon RX 9070 holds a rank of 1062 out of 3723 combos. This places it in the upper third of all systems tested, indicating that it is a capable pairing for this game. The percentile data for the individual components supports this: the CPU is in the 72nd percentile of all CPUs, and the GPU is in the 69th percentile of all GPUs.
