Rust

The Intel Core i3-12100F paired with the AMD Radeon RX 9070 XT presents a notable imbalance in Rust, where a strong GPU is held back by a modest four-core processor. The benchmark data, however, shows this combination still delivers playable performance across most settings, with the CPU becoming the primary constraint only at lower resolutions and settings. This analysis breaks down the measured FPS data, compares the components to their nearest rivals, and explains which part drives performance at each resolution.

Similar Performance Alternatives

The CPU and GPU in this combo each sit near distinct performance clusters. The Intel Core i3-12100F has an average benchmark score of 13494, placing it in the 68th percentile of all CPUs. Its nearest rivals are remarkably close in score: the Intel Core 3 N355 matches at 13492 (0% delta), the Intel Core i5-9500 scores 13452 (0.3% behind), the Intel Core 5 120UL scores 13594 (0.7% ahead), and the Intel Core i7-1250U scores 13351 (1.1% behind). For Rust, this means the i3-12100F will behave nearly identically to these four CPUs in CPU-bound scenarios, such as large multiplayer servers or low-resolution high-FPS situations. The i3-12100F’s 4 cores and 8 threads are the limiting factor here, not its clock speeds, which boost to 4.30 GHz.

The GPU side shows a more surprising picture. The AMD Radeon RX 9070 XT has an average benchmark score of 13543, placing it in the 55th percentile of all GPUs. Its nearest rivals are significantly older parts: the AMD Radeon HD 7770M scores 13536 (0.1% behind), the NVIDIA GeForce GTX 570 scores 13515 (0.2% behind), the NVIDIA P106-090 scores 13470 (0.5% behind), and the AMD Radeon Pro 555 scores 13407 (1% behind). Although these rivals are generations old, the benchmark data indicates the RX 9070 XT produces similar average scores. In Rust, this implies that the GPU is not the bottleneck at most settings — the CPU limits frame rates before the GPU’s full potential is used, especially at 1080p and 1440p where the GPU has headroom to spare.

Best Settings per Resolution

The measured FPS data identifies the most demanding preset that stays at or above 60 FPS at each resolution. At 1920x1080, the Ultra preset delivers 99.6 FPS average, which clears the 60 FPS threshold comfortably. This is the best setting available at this resolution. The High preset runs at 125.9 FPS, Medium at 149.9 FPS, and Low at 201.5 FPS, but Ultra is the highest quality option that remains playable.

At 2560x1440, the Ultra preset also qualifies as the best playable setting, with an average of 67.4 FPS. This narrowly clears the 60 FPS mark. The High preset runs at 85.9 FPS, Medium at 102.9 FPS, and Low at 156.2 FPS, but Ultra is the most demanding that still maintains playability. The margin above 60 FPS is thinner here than at 1080p, so users should expect occasional dips below the average in heavy scenes.

At 3840x2160, the situation changes. The Low preset is the only playable option, averaging 88.4 FPS. The Medium preset drops to 58.7 FPS, which is below the 60 FPS threshold, High falls to 52.2 FPS, and Ultra collapses to 37.3 FPS. The data shows no playable setting above Low at 4K. This is a clear case where the CPU-GPU imbalance becomes critical: the i3-12100F cannot feed the RX 9070 XT enough data to maintain higher frame rates at 4K, even though the GPU has the raw compute capability.

CPU and GPU Roles

The scaling between resolutions and presets reveals which component dominates performance. At 1920x1080, the difference between Low and Ultra is 101.9 FPS (from 201.5 to 99.6). This large gap indicates the GPU is the primary driver — lowering settings reduces GPU load, and the CPU can keep up with the resulting frame rates. The CPU is not the bottleneck here; it can issue draw calls fast enough to support over 200 FPS at Low settings.

At 2560x1440, the scaling pattern shifts. The difference between Low (156.2 FPS) and Ultra (67.4 FPS) is 88.8 FPS, which is still substantial but smaller than at 1080p. The CPU begins to matter more: at Low settings, the frame rate drops from 201.5 at 1080p to 156.2 at 1440p, a 22% reduction. This is partially due to the GPU working harder, but the CPU’s 4-core/8-thread design also starts to limit the maximum achievable FPS. The i3-12100F’s single-thread performance, measured at 1674 in Cinebench R23 single-core, is adequate but not extraordinary.

At 3840x2160, the CPU-GPU roles invert dramatically. The difference between Low (88.4 FPS) and Ultra (37.3 FPS) is 51.1 FPS, but the absolute numbers are much lower. The CPU is now the clear bottleneck. Even at Low settings, the frame rate drops from 156.2 at 1440p to 88.4 at 4K — a 43% reduction that cannot be explained by GPU workload alone. The RX 9070 XT has 16 GB of GDDR6 memory and 644.6 GB/s bandwidth, which is more than sufficient for 4K textures. The limitation is the CPU’s ability to process game logic and physics for Rust’s large, complex worlds. The i3-12100F’s 12 MB of shared L3 cache is small for a game that streams assets constantly, and its 4 cores cannot parallelize the many background tasks Rust requires.

The Verdict

This PC can run Rust, but the playable range is heavily dependent on resolution. At 1920x1080, all four presets — Low, Medium, High, and Ultra — clear the 60 FPS threshold, with Ultra averaging 99.6 FPS. This is the sweet spot: the GPU has enough headroom to handle Ultra settings, and the CPU provides sufficient throughput. At 2560x1440, all four presets also clear 60 FPS, with Ultra at 67.4 FPS. This is playable but leaves little margin for demanding scenes, such as large bases or PvP fights. At 3840x2160, only the Low preset is playable, averaging 88.4 FPS. Medium (58.7 FPS), High (52.2 FPS), and Ultra (37.3 FPS) all fall below the 60 FPS threshold. The verdict is straightforward: this combo is best suited for 1080p and 1440p gaming, and 4K users must stick to Low settings.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across all combinations of resolutions and settings. At 1920x1080, Low averages 201.5 FPS, Medium averages 149.9 FPS, High averages 125.9 FPS, and Ultra averages 99.6 FPS. The gap between Low and Ultra is 101.9 FPS, showing strong GPU scaling. At 2560x1440, Low averages 156.2 FPS, Medium averages 102.9 FPS, High averages 85.9 FPS, and Ultra averages 67.4 FPS. The gap between Low and Ultra narrows to 88.8 FPS, indicating the CPU begins to cap the maximum frame rate. At 3840x2160, Low averages 88.4 FPS, Medium averages 58.7 FPS, High averages 52.2 FPS, and Ultra averages 37.3 FPS. The gap between Low and Ultra shrinks further to 51.1 FPS, and the absolute numbers drop significantly. The minimum and maximum FPS values are not recorded in the data, so the analysis relies on average FPS only. The playable threshold is set at 60 FPS, which the data respects: 4K Medium (58.7 FPS) is just below, while 1440p Ultra (67.4 FPS) is just above.

How This Combo Ranks

Among all tested CPU-GPU combinations in Rust, this pair ranks 955th out of 3723 combos, placing it in the top 26% of all tested systems. This rank reflects the measured FPS data across all resolutions and settings. The combination’s position is higher than the individual component percentiles might suggest — the CPU is in the 68th percentile and the GPU is in the 55th percentile — because Rust is more CPU-intensive than many other games. The i3-12100F’s strong single-thread performance (1674 in Cinebench R23 single-core) helps it punch above its weight in Rust’s simulation-heavy gameplay. However, the 955th rank also indicates that many other combos deliver higher frame rates, particularly those with more powerful CPUs. For users with this exact combo, the data suggests focusing on 1080p or 1440p gaming, where the RX 9070 XT can stretch its legs and the CPU keeps pace. At 4K, the rank would likely be lower if measured separately, as the CPU bottleneck becomes severe. Overall, this is a capable mid-range gaming system for Rust, but not a top-tier one.
