Rust

The Intel Core i3-12100F is a 4-core, 8-thread processor based on the Alder Lake architecture, with a base clock of 3.30 GHz and a boost clock of 4.30 GHz. In Rust, this CPU configuration demonstrates a distinct pattern: the game’s performance scales noticeably with resolution and settings, but the CPU’s 12 MB of shared L3 cache and dual-channel memory support are the primary architectural traits that influence frame pacing. The benchmark data shows that at 1920x1080 with Low settings, the combo achieves 171.8 FPS, which is the highest measured average across all configurations. This suggests that at lower graphical loads, the CPU is capable of feeding the GPU sufficiently to reach high frame rates. However, as resolution increases to 2560x1440, the frame rate drops to 117.3 FPS at Low settings, and at 3840x2160 it falls to 67.3 FPS. This scaling indicates that while the CPU is not the absolute bottleneck at lower resolutions, its 4-core/8-thread layout limits the headroom for maintaining high FPS when the GPU is less stressed, because Rust’s simulation and entity update logic often rely on single-thread performance. The 3DMark single-thread score of 893 and Geekbench single-core score of 2224 place this CPU in the 72nd percentile of all processors, showing it has solid single-core capability for a game like Rust that is known to be sensitive to per-core performance. The 3DMark 4-thread score of 2859 and 8-thread score of 4026 indicate that the processor scales well with its available threads, but the max-thread score of 4023 is nearly identical to the 8-thread score, confirming that the 8 threads are fully utilized but additional threads would not help. In the context of this game’s measured results, the CPU appears to be a competent partner for the GPU at 1080p, but the data shows a 19.3% performance drop from 1920x1080 Low to 2560x1440 Low, which is a larger relative decline than what would be expected if the CPU were the sole limiting factor, suggesting that the GPU also plays a significant role in these settings.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i3-12100F’s specifications—4 cores, 8 threads, with a 4.30 GHz boost clock—are directly reflected in the measured FPS data for Rust. At 1920x1080 with Low settings, the combo reaches 171.8 FPS, which is the highest average recorded across all resolutions and settings. This indicates that the CPU’s single-thread performance, evidenced by its 3DMark single-thread score of 893 and PassMark single-thread score of 3444, is sufficient to drive high frame rates when the GPU is not heavily burdened. The CPU’s 3DMark 4-thread score of 2859 and 8-thread score of 4026 show that the processor can efficiently use its available threads, but the game’s engine likely does not scale perfectly with all 8 threads, as the max-thread score of 4023 is essentially identical to the 8-thread result. This suggests that Rust’s core simulation loop is bound to a limited number of threads, making the i3-12100F’s high boost clock more relevant than its core count. When moving to 2560x1440 Low, the average FPS drops to 117.3, a 31.7% decrease from 1080p Low, which implies that while the CPU is still capable, the increased pixel workload shifts more responsibility to the GPU. At 3840x2160 Low, the FPS falls further to 67.3, a 42.6% drop from 1440p Low, showing that the CPU’s limitations become more apparent at higher resolutions when the GPU is less able to mask latency. The CPU’s position in the 72nd percentile of all CPUs, with an average benchmark score of 13516, places it just 0.1% below the AMD Ryzen Threadripper PRO 3975WX and 1.8% above the Intel Core i7-7700K, indicating that its performance is competitive with older high-end parts but not with modern multi-core flagships. In Rust, the data shows that this CPU provides enough headroom for playable frame rates at 1080p, but the 4-core limit becomes a constraint at higher resolutions where the GPU’s workload increases, leading to a more balanced system that still delivers acceptable performance.

GPU Role — VRAM, clocks, and how they relate to this game's results

The AMD Radeon RX 6750 XT is a RDNA 2.0 architecture GPU with 12 GB of GDDR6 memory on a 192-bit bus, providing 432.0 GB/s of bandwidth. Its base clock of 2150 MHz and boost clock of 2600 MHz, with a game clock of 2495 MHz, are key factors in the measured FPS across Rust’s settings. The GPU’s 40 ray accelerators and 2560 shading units contribute to its ability to handle the game’s environmental rendering, but the data shows that the GPU’s performance is heavily influenced by the chosen preset. At 1920x1080 with Ultra settings, the combo achieves 72.9 FPS, which is 57.6% lower than the 171.8 FPS at Low settings. This dramatic drop indicates that the GPU is the primary bottleneck when graphical features are maximized, as the increased shading and texture work overwhelm the GPU’s compute capabilities. The GPU’s PassMark G3D score of 20700 and 3DMark Steel Nomad DX12 score of 2548 place it in the 79th percentile of all GPUs, with an average benchmark score of 35327. Its nearest rival, the NVIDIA GeForce RTX 3080, is only 1.3% faster in average score, while the AMD Radeon RX 5600M is 0.2% slower, showing that the RX 6750 XT sits in a competitive mid-to-high tier. In Rust, the GPU’s 12 GB VRAM is more than sufficient for the game’s texture requirements, as evidenced by the steady performance at 2560x1440 High (66 FPS) compared to 3840x2160 High (41.1 FPS), where the higher resolution demands more memory bandwidth. The GPU’s 18 Gbps effective memory speed and 432.0 GB/s bandwidth are adequate for 1440p gaming, but at 4K Ultra (28.4 FPS), the GPU’s pixel rate of 166.4 GPixel/s becomes a limiting factor, unable to sustain fluid frame rates. The data shows that the RX 6750 XT is a capable partner for the i3-12100F at 1080p and 1440p, but it struggles at 4K Ultra, where the combination of high resolution and maximum settings pushes the GPU beyond its comfort zone.

At 3840x2160, the Ultra preset’s 28.4 FPS is limited by the GPU’s 166.4 GPixel/s pixel rate rather than VRAM capacity.

Settings Recommendations

The measured FPS data for this Intel Core i3-12100F and AMD Radeon RX 6750 XT combination reveals a clear hierarchy of settings presets across three resolutions. At 1920x1080, the High preset delivers 97.9 FPS, which is 14.6% lower than the Medium preset’s 114.7 FPS but provides substantially better visual quality. The Ultra preset at 72.9 FPS is 25.5% slower than High, making it less desirable for competitive play. For most users at 1080p, the High preset offers the best balance, as it maintains frame rates above 90 FPS while providing detailed textures and effects. At 2560x1440, the Medium preset emerges as the most sensible choice, with 79.7 FPS compared to High’s 66 FPS and Ultra’s 50.4 FPS. The 20.8% performance gain from Medium over High is significant, and the visual difference between these two settings is often less noticeable than the frame rate improvement. The Low preset at 1440p (117.3 FPS) is an option for users prioritizing high refresh rates, but it sacrifices too much visual fidelity for a 47.2% gain over Medium. At 3840x2160, the data shows that no preset provides a consistently smooth experience: Low averages 67.3 FPS, Medium 45.3 FPS, High 41.1 FPS, and Ultra 28.4 FPS. For 4K gaming, the Low preset is the only viable option for playable frame rates, but even then, the 67.3 FPS average is not ideal for fast-paced survival gameplay. The best overall experience per the measured rows is achieved at 1920x1080 with High settings (97.9 FPS), as it combines strong visual quality with frame rates that are 34.3% higher than the 1440p Medium preset’s 79.7 FPS. For users with higher-resolution displays, 1440p Medium is the recommended compromise, offering 79.7 FPS that is 18.2% higher than the 1080p Ultra preset’s 72.9 FPS, making it a more efficient use of the GPU’s capabilities.

How This Combo Ranks

The Intel Core i3-12100F and AMD Radeon RX 6750 XT combination ranks 857th out of 1717 tested combos in Rust, placing it almost exactly in the middle of the distribution. This rank is a composite of the CPU’s 72nd percentile performance (average benchmark score of 13516) and the GPU’s 79th percentile performance (average benchmark score of 35327), but the measured FPS data shows that the combo’s actual in-game performance is more nuanced than these aggregate scores suggest. The CPU’s nearest rival, the AMD Ryzen Threadripper PRO 3975WX, has an average score 0.1% higher, while the Intel Core i7-1250U is 0.4% lower, indicating that the i3-12100F’s processing power is on par with much more expensive parts in synthetic benchmarks, but its 4-core/8-thread configuration limits its real-world performance in heavily threaded scenarios. The GPU’s nearest rival, the NVIDIA GeForce RTX 3080, is 1.3% faster in average score, while the AMD Radeon RX 5600M is 0.2% slower, showing that the RX 6750 XT is competitive with higher-tier GPUs from other generations. In Rust specifically, the combo’s rank of 857/1717 suggests that it outperforms many combinations with more powerful CPUs but weaker GPUs, and vice versa. The measured FPS at 1920x1080 High (97.9 FPS) is 48.4% higher than at 3840x2160 High (41.1 FPS), demonstrating that the combo’s performance is heavily dependent on resolution. The rank reflects this variability: the combo is well-suited for 1080p gaming, where it achieves frame rates above 90 FPS on High settings, but it falls behind at 4K Ultra, where the 28.4 FPS average is below the threshold for smooth gameplay. Compared to other combos in the database, this pairing sits in the same performance tier as systems with mid-range CPUs and GPUs, offering a balanced experience that is neither exceptional nor underwhelming. The data indicates that the combo’s rank is primarily driven by the GPU’s ability to handle lower resolutions efficiently, while the CPU’s single-thread strength ensures that it does not become a bottleneck at 1080p. At higher resolutions, the combo’s rank would likely drop, as the GPU’s limitations become more pronounced, but the measured results show that for most players using 1080p or 1440p displays, this combination offers a competitive experience in Rust.
