Rust

The Intel Core i3-12100F paired with the NVIDIA GeForce RTX 4090 is a lopsided combination that, in Rust, still delivers a broadly playable experience across most resolutions and settings. The data shows that at 4K, the combo only fails to hit the 60 FPS playable threshold at the Ultra preset, while at 1440p and 1080p, every settings level from Low to Ultra clears that mark comfortably. The most striking finding is that this pairing produces an average of 202 FPS at 1080p Low and 137 FPS at 1080p Ultra, proving that the RTX 4090’s raw power can overcome the Core i3-12100F’s four-core limitation in this particular survival title.

Measured FPS Breakdown

The measured FPS data for Rust reveals a clear performance hierarchy across resolutions and presets. At 3840x2160, the results are as follows: Low settings produce an average of 129 FPS, Medium yields 87 FPS with a minimum of 74 and maximum of 100, High reaches 73 FPS, and Ultra drops to 56 FPS. The Ultra preset is the only configuration at 4K that falls below the 60 FPS playable threshold, and the gap is significant—the 56 FPS average represents a 23% drop from the High preset’s 73 FPS. The Medium setting, with its 74 FPS minimum, still maintains a buffer above the playable line, but the Ultra’s lack of min/max data suggests the average is the primary reference point.

Moving to 2560x1440, the performance improves substantially across all presets. Low settings average 178 FPS, Medium averages 147 FPS with a minimum of 125 and maximum of 169, High reaches 124 FPS, and Ultra delivers 94 FPS. The jump from 4K to 1440p is most pronounced at the Ultra preset, where the average climbs from 56 FPS to 94 FPS—a 68% increase. Even the Medium setting at 1440p, with its 125 FPS minimum, never approaches the 60 FPS threshold. The High preset’s 124 FPS average is notably lower than Medium’s 147 FPS, indicating that the graphical load scaling between these two settings is non-linear.

At 1920x1080, the combo reaches its peak performance. Low settings average 202 FPS, Medium averages 173 FPS with a minimum of 147 and maximum of 199, High achieves 163 FPS, and Ultra still manages 137 FPS. The 1080p Ultra result is particularly telling—it is 2.4 times faster than the 4K Ultra average, showing how resolution scaling heavily impacts this game’s frame rate. The Medium preset’s 147 FPS minimum is higher than the 4K High average, which underscores the CPU’s ability to feed the GPU at lower resolutions. Across all presets at 1080p, the minimum recorded frame rate is 147 FPS, which is more than double the playable threshold.

The data reveals that Rust’s frame rate scaling is not linear with resolution. From 1080p to 1440p, the average FPS drops by roughly 30-40% across presets (e.g., Ultra from 137 to 94, Medium from 173 to 147). From 1440p to 4K, the drop is even steeper, with Ultra falling from 94 to 56 FPS and High from 124 to 73 FPS. This suggests that at 4K, the GPU becomes the primary bottleneck, while at 1080p, the CPU’s capabilities start to limit maximum frame rates.

CPU and GPU Roles

The benchmark results indicate that the NVIDIA GeForce RTX 4090 is the dominant component in this pairing, but the Intel Core i3-12100F’s role becomes more significant as resolution decreases. At 3840x2160, the GPU’s workload is immense—the RTX 4090’s 82.58 TFLOPS FP32 performance and 24 GB of GDDR6X memory are pushed hard, and the CPU’s four cores are sufficient to keep up with the GPU’s output. This is evidenced by the 4K Ultra result of 56 FPS, where the GPU’s rendering demands outpace what the CPU can feed it, but the 4K Low result of 129 FPS shows that when the GPU load is reduced, the CPU can still deliver high frame rates.

At 2560x1440, the balance shifts slightly. The CPU’s 3DMark scores—4051 for 16 threads and 4026 for 8 threads—suggest that it can handle the game’s multi-threaded demands at this resolution. The 1440p Ultra average of 94 FPS is more than 60% higher than the 4K Ultra result, indicating that the GPU’s workload is easing and the CPU is no longer the limiting factor. The 1440p Low result of 178 FPS further confirms this, as the CPU’s single-thread performance (3DMark single-thread score of 893, Cinebench R23 single-core score of 1674) becomes more relevant when the GPU is less taxed.

At 1920x1080, the CPU’s role becomes the dominant constraint. The 1080p Low average of 202 FPS and Ultra average of 137 FPS show that the RTX 4090 is capable of far higher frame rates, but the Core i3-12100F’s four cores and 8 threads limit the maximum output. The CPU’s Cinebench R23 multi-core score of 11860 and Passmark multi-thread score of 14015 are modest compared to higher-core-count CPUs, but they are sufficient to maintain 137 FPS at Ultra. The scaling between presets at 1080p is relatively narrow—from 137 to 202 FPS—which suggests that the CPU is the primary bottleneck, not the GPU.

The resolution scaling data reinforces this analysis. From 1080p to 4K, the average FPS at Ultra drops from 137 to 56, a 59% reduction. This is a much steeper drop than would be expected if the CPU were the sole limiting factor, indicating that the GPU is heavily taxed at 4K. Conversely, the Low preset at 1080p (202 FPS) versus 4K (129 FPS) shows a 37% reduction, which is more moderate but still significant. The conclusion is that the RTX 4090 dominates performance at 4K, while the Core i3-12100F limits ceiling frame rates at 1080p.

Similar Performance Alternatives

The nearest rivals for the Intel Core i3-12100F, based on average benchmark scores, provide context for its CPU performance. The Intel Core 3 N355 matches the i3-12100F with an average score of 13492 and a delta of 0%, meaning they perform identically in synthetic benchmarks. The Intel Core i5-9500 scores 13452, which is 0.3% lower, placing it in the same performance tier. The Intel Core 5 120UL scores 13594, which is 0.7% higher, and the Intel Core i7-1250U scores 13351, which is 1.1% lower. These rivals suggest that the i3-12100F’s performance is comparable to a mix of older desktop and modern low-power mobile chips, all within a 2% delta band.

For the NVIDIA GeForce RTX 4090, the nearest rivals are equally telling. The Intel Arc Pro A60 matches the RTX 4090 with an average score of 60326 and a 0% delta, which is surprising given the huge difference in raw specs—the RTX 4090 has 16384 shading units and 128 RT cores, while the Arc Pro A60 is a workstation card. The AMD Radeon Pro Vega 48 scores 60140, a 0.3% delta, and the AMD Radeon Pro W6600M scores 61896, which is 2.5% higher. The AMD Radeon PRO V710 scores 58657, a 2.9% lower result. These rivals are all professional or workstation GPUs, indicating that the RTX 4090’s average benchmark score places it in a tier with these specialized cards, despite its gaming focus.

In practical terms for Rust, the CPU rivals would likely produce similar frame rates at 1080p, where the CPU is the bottleneck. The GPU rivals, being workstation-class, might not perform as well in gaming workloads, but the benchmark data shows they are statistically similar in synthetic tests. The deltaPct values of 0% to 2.9% suggest that swapping the RTX 4090 for one of these rivals would result in minimal performance differences in Rust, though the gaming-specific features of the RTX 4090—such as its 82.58 TFLOPS FP32 and 1.01 TB/s memory bandwidth—would still give it an edge in real-world gaming.

The Verdict

Can this PC run Rust? The verdict by resolution is unambiguous: yes, at nearly every settings level. At 3840x2160, the playable settings are High, Low, and Medium, with the best setting being High at an average of 73 FPS. The Ultra preset is not playable, as its 56 FPS average falls below the 60 FPS threshold. This means that 4K gamers can enjoy Rust at High settings with a comfortable margin, but must avoid Ultra.

At 2560x1440, all four settings—High, Low, Medium, and Ultra—are playable. The best setting is Ultra, which averages 94 FPS, providing a 34 FPS buffer above the playable threshold. Even the Medium preset’s minimum of 125 FPS is more than double the 60 FPS line. This resolution is the sweet spot for this combo, offering high visual fidelity without compromising frame rate.

At 1920x1080, the verdict is equally positive. All settings are playable, with Ultra averaging 137 FPS, which is more than double the playable threshold. The Low preset’s 202 FPS average is the highest recorded in the data, indicating that the CPU can push very high frame rates when the GPU is not stressed. For competitive play, 1080p Low or Medium would be ideal, while 1080p Ultra offers a smooth experience at 137 FPS.

The data confirms that this combo can run Rust across the board, with the only exception being 4K Ultra. The 60 FPS playable threshold is cleared by at least 13 FPS at every playable resolution and preset combination, and the 4K High result of 73 FPS provides a 22% margin. For users with 4K monitors, dropping to High settings is a minor compromise for a fully playable experience.

How This Combo Ranks

The combination of Intel Core i3-12100F and NVIDIA GeForce RTX 4090 ranks 225th out of 3723 tested combos in Rust, placing it in the top 6% of all systems tested. This is a strong result, particularly given the CPU’s modest specifications. The rank reflects the RTX 4090’s dominance in synthetic benchmarks—its average benchmark score of 60347 places it in the 88th percentile of all GPUs—while the CPU’s 68th percentile ranking is a limiting factor.

The combo’s rank of 225 out of 3723 suggests that it outperforms the vast majority of systems, but it is not at the very top. This is likely due to the CPU bottleneck at lower resolutions, where other combos with more powerful CPUs (e.g., Core i9 or Ryzen 9) would achieve higher frame rates. The data shows that at 1080p Low, the combo averages 202 FPS, which is impressive but not the highest possible. The RTX 4090’s 88th percentile GPU ranking is the primary driver of the combo’s high rank, while the CPU’s 68th percentile pulls it down.

In the context of all tested combos, this pairing is in the upper echelon, but it is not a top-tier performer. The rank of 225 out of 3723 means that 94% of tested systems score lower, which reflects the RTX 4090’s power. However, the gap between this combo and the top-ranked systems would be larger at 1080p than at 4K, where the GPU’s workload is more significant and the CPU’s limitations are less exposed.
