Rust

The Intel Core i3-12100F paired with the NVIDIA GeForce RTX 4070 delivers a wide spread of frame rates in Rust, with the measured data showing the GPU becoming the primary limiting factor only at the highest resolutions. At 1920x1080, the combo produces a Low preset average of 204.2 FPS, which collapses to 100.1 FPS at the Ultra preset, indicating that the 4-core, 8-thread processor is still capable of feeding the GPU at this resolution. Moving to 2560x1440, the Low preset still yields 156.4 FPS, but the Ultra preset drops to 69.7 FPS, showing a 55% reduction in performance from the lowest to the highest settings. At 3840x2160, the scaling becomes more dramatic: the Low preset averages 93.3 FPS, while the Ultra preset plummets to 36.8 FPS, a 61% loss. The data suggests that at 4K, the RTX 4070’s rendering workload dominates, as the drop from Low to Ultra at this resolution is steeper than the drop from 1080p Low to Ultra, which is only 51%. This indicates that at 1080p and 1440p, the CPU can still keep pace with the GPU, but at 4K, the GPU’s pixel throughput becomes the bottleneck, with the High preset at 4K delivering 54.4 FPS versus 87.9 FPS at 1440p High.

Resolution Scaling

The frame rate deltas across resolutions reveal how the RTX 4070’s compute resources are taxed as pixel count increases. From 1920x1080 High to 2560x1440 High, the average FPS drops from 129.6 to 87.9, a 32% reduction. Pushing further to 3840x2160 High, the average falls to 54.4, which is a 58% decline from the 1080p figure. This scaling pattern is consistent with a GPU-bound scenario at higher resolutions, as the CPU’s role diminishes when more pixels are being shaded. The Low preset shows a similar trend: 204.2 FPS at 1080p, 156.4 FPS at 1440p (a 23% drop), and 93.3 FPS at 4K (a 54% drop from 1080p). Interestingly, the Medium preset at 4K (60.9 FPS) is closer to the High preset at 1440p (87.9 FPS) than to the High preset at 4K (54.4 FPS), suggesting that the jump from Medium to High at 4K carries a significant rendering cost. The Ultra preset is the most demanding, with 4K Ultra (36.8 FPS) being nearly unplayable for smooth gameplay, while 1440p Ultra (69.7 FPS) and 1080p Ultra (100.1 FPS) remain viable. The data indicates that the limiting component shifts from the CPU at 1080p Low (where the GPU can push 204.2 FPS) to the GPU at 4K Ultra (where the CPU’s 4 cores are less relevant to the 36.8 FPS result). The RTX 4070’s 12 GB of GDDR6X memory and 192-bit bus provide ample bandwidth, but the 504.2 GB/s throughput is still insufficient to maintain high frame rates at 4K with Ultra settings, as evidenced by the 36.8 FPS result.

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor from the Alder Lake architecture, with a base clock of 3.30 GHz and a boost clock of 4.30 GHz. Its benchmark scores place it in the 72nd percentile of all CPUs, with a Cinebench R23 multicore score of 11912 and a single-core score of 1681. In Rust, which is known for its physics and entity simulation, the CPU’s single-thread performance is critical. The 3DMark single-thread score of 893 and the Geekbench single-core score of 2224 show that the i3-12100F has solid per-core speed, which helps maintain frame rates at lower resolutions. At 1080p Low, the combo achieves 204.2 FPS, a result that would be impossible if the CPU were severely bottlenecked. However, the CPU’s 12 MB of shared L3 cache and 58 W TDP suggest it is a budget-oriented part, and its nearest rivals include the AMD Ryzen Threadripper PRO 3975WX (which scores 13534, just 0.1% higher) and the Intel Core i7-7700K (which scores 13280, 1.8% lower). The data shows that the i3-12100F’s 4 cores are sufficient to drive the RTX 4070 in Rust at 1080p and 1440p, but the frame rate differences between Low and Ultra at these resolutions (204.2 vs 100.1 at 1080p) indicate that the GPU is still the primary constraint at higher settings. At 4K, the CPU’s role diminishes further, as the GPU’s pixel shader workload becomes dominant. The processor’s PassMark multithread score of 14015 and its 8 threads help with Rust’s server-side and background tasks, but the benchmark results suggest that a higher-core-count CPU would not significantly improve the measured FPS at 4K Ultra, given the GPU’s 36.8 FPS limit.

Settings Recommendations

Based on the measured FPS rows, the optimal preset for this combo depends on the target resolution and desired smoothness. At 1920x1080, the High preset delivers 129.6 FPS, which is well above the 60 FPS threshold, while the Medium preset offers 151.7 FPS, a 17% improvement over High. The Low preset at 204.2 FPS is overkill for most displays, but it shows the headroom available. For a balanced experience, Medium at 1080p (151.7 FPS) provides the best combination of visual quality and frame rate, as the jump to High costs 22 FPS (a 15% drop) while the jump to Ultra costs 51.6 FPS (a 34% drop from Medium). At 2560x1440, the Medium preset (101.6 FPS) is the clear choice, as it maintains a triple-digit frame rate while High (87.9 FPS) and Ultra (69.7 FPS) fall below 100 FPS. The Low preset at 1440p (156.4 FPS) sacrifices too much visual fidelity for a frame rate that exceeds most 144Hz monitors. At 3840x2160, the Medium preset (60.9 FPS) is the only setting that approaches a playable 60 FPS, while High (54.4 FPS) is borderline and Ultra (36.8 FPS) is not recommended. The data shows that the Medium preset offers the best experience across all resolutions, with a 42% improvement over High at 4K (60.9 vs 54.4) and a 51% improvement over Ultra at 1080p (151.7 vs 100.1). For users with high-refresh-rate 1440p monitors, Low (156.4 FPS) is the only preset that fully saturates a 144Hz panel, but Medium (101.6 FPS) is still smooth for most gameplay.

How This Combo Ranks

The combination of the Intel Core i3-12100F and the NVIDIA GeForce RTX 4070 achieves a combo rank of 408 out of 1717 tested combinations in Rust, placing it in the top 24% of all systems. This rank reflects the balance between the CPU’s 4 cores and the GPU’s high-end performance. The RTX 4070 alone sits in the 81st percentile of all GPUs, with a PassMark G3D score of 26927, while the i3-12100F is in the 72nd percentile of all CPUs. The combo’s rank is slightly higher than the GPU’s percentile, suggesting that the CPU is not a significant drag in Rust’s specific workload. The nearest GPU rivals to the RTX 4070 include the AMD Radeon RX Vega 56 (which scores 37507, just 0.6% higher) and the NVIDIA GeForce RTX 4080 Mobile (which scores 38135, 2.2% higher), but these comparisons are for raw GPU compute, not gaming frame rates. The combo’s rank of 408 means that 1309 other combinations outperform it, but many of those likely use higher-end CPUs such as the Ryzen Threadripper PRO 3975WX, which scores 13534 on average, 0.1% higher than the i3-12100F. The data indicates that this combo is well-suited for 1080p and 1440p gaming, but it falls behind in the 4K Ultra segment, where the 36.8 FPS result places it below systems with more powerful GPUs. The RTX 4070’s 29.15 TFLOPS of FP32 performance and 46 RT cores are sufficient for Rust’s DirectX 12 rendering, but the combo’s rank shows that a stronger CPU would not move the needle much at higher resolutions, as the GPU is the limiting factor.
