Rust

The Intel Core i3-12100F paired with the NVIDIA GeForce RTX 4080 SUPER lands at rank 135 out of 1,717 tested combinations in Rust. That places this build in the top 7.9% of all combos, a strong showing that reflects a high-end GPU doing most of the heavy lifting. The data suggests this pairing is far from a bottleneck-limited setup, but the rank also hints that the quad-core processor is not maximizing the GPU's potential in every scenario. The delta between this combo's rank and what the GPU alone could achieve implies the CPU is holding back some frames, especially at lower resolutions where the graphics card waits on the processor.

How This Combo Ranks

At position 135 of 1,717, this combo sits in the 92nd percentile of tested configurations. The ranking is heavily influenced by the RTX 4080 SUPER, whose average benchmark score of 53,610 places it in the 88th percentile among all GPUs. The CPU, however, is less dominant — the i3-12100F's average score of 13,516 lands in the 72nd percentile, and its nearest rivals show how close the competition is. The AMD Ryzen Threadripper PRO 3975WX scores 13,534, a mere 0.1% difference, while the Intel Core i7-1250U is 0.4% behind. This tells a clear story: the CPU is performing at a level where tiny margins separate it from many others, but the GPU's raw power boosts the entire system's ranking. The gap between the CPU's percentile and the combo's overall rank suggests Rust's engine leans heavily on the graphics card for the frame rates observed.

GPU Role

The RTX 4080 SUPER brings 16 GB of GDDR6X memory on a 256-bit bus, delivering 736.3 GB/s of bandwidth. The memory clock runs at 1438 MHz, translating to 23 Gbps effective, which is critical for Rust's large, streaming world. The GPU's boost clock of 2550 MHz (base 2295 MHz) drives its 52.22 TFLOPS of FP32 performance, and the 80 RT cores and 320 tensor cores handle any advanced effects. In Rust, the data shows the GPU being the dominant factor: at 4K Ultra, the combo still produces 47.6 FPS, a playable level for a survival title, while dropping settings to Low at 4K yields 117 FPS. The GPU's 88th percentile ranking among all GPUs aligns with these results — it is clearly capable of pushing high frame rates, but the CPU's limitations become apparent when comparing settings at the same resolution. The 45,900 million transistors on TSMC's 5 nm process (379 mm² die) provide the computational headroom, yet the frame data indicates that the processor is the constraining element in lower-resolution scenarios.

Resolution Scaling

The measured FPS reveals a predictable pattern: performance scales inversely with resolution. At 1080p High, the combo delivers 160 FPS, dropping to 114 FPS at 1440p High, and further to 66.9 FPS at 4K High. This represents a 28.8% drop from 1080p to 1440p and a 41.3% drop from 1440p to 4K. The scaling is more dramatic at Ultra settings: 123.3 FPS at 1080p, 86.7 FPS at 1440p, and 47.6 FPS at 4K — a 61.4% reduction from 1080p to 4K. These numbers indicate that at 1080p, the CPU is likely the bottleneck, as the GPU has spare capacity that the quad-core cannot feed. At 4K, the GPU becomes the limiting factor, as the frame rate drops significantly regardless of settings. The Low settings at 1080p hit 201.4 FPS, suggesting the CPU is nearly maxed out, while the same settings at 4K yield 117 FPS, showing the GPU is now the constraint. This crossover point occurs somewhere between 1440p and 4K, where the workload shifts from CPU-bound to GPU-bound.

FAQ

Q: Does this combo run Rust at 60 FPS on 4K Ultra?

A: No. The measured average at 3840x2160 Ultra is 47.6 FPS, which falls short of a smooth 60 FPS target. Dropping to High settings at 4K raises this to 66.9 FPS.

Q: Is the i3-12100F a bottleneck for the RTX 4080 SUPER in Rust?

A: The data suggests yes at lower resolutions. At 1080p Low, the combo reaches 201.4 FPS, but the CPU's 4 cores and 8 threads (with a boost clock of 4.30 GHz) appear to limit the GPU, as the RTX 4080 SUPER's raw power could likely push higher frame rates in a less CPU-dependent title.

Q: What is the best resolution for this pairing?

A: 2560x1440 offers the best balance. At Medium settings, the combo delivers 133.8 FPS, which is smooth for competitive play, while High settings at 1440p still achieve 114 FPS. The 4K results are playable but require lower settings.

Q: How does the CPU's benchmark score compare to its rivals?

A: The i3-12100F scores 13,516 on average, which is 0.1% below the AMD Ryzen Threadripper PRO 3975WX (13,534) and 0.4% above the Intel Core i7-1250U (13,462). It sits 1.8% ahead of the Intel Core i7-7700K (13,280).

Q: Does the GPU's 16 GB VRAM matter for Rust?

A: The 16 GB GDDR6X memory with 736.3 GB/s bandwidth is more than sufficient for Rust's requirements, even at 4K Ultra. The bottleneck at that resolution is compute, not memory capacity, as evidenced by the 47.6 FPS at 4K Ultra.

Q: What FPS can I expect at 1080p with High settings?

A: The measured average is 160 FPS. This is well above the typical 144 Hz refresh rate, making this combo excellent for high-refresh monitors at 1080p.

CPU Role

The Intel Core i3-12100F is a 4-core, 8-thread processor based on Alder Lake architecture, built on Intel's 10 nm process. Its base clock of 3.30 GHz boosts to 4.30 GHz, and it carries 12 MB of shared L3 cache. The 3DMark scores illustrate its multi-threaded potential: 4,051 for 16 threads and 4,023 for max threads, showing that scaling beyond 8 threads yields little gain. Cinebench R23 results show 11,912 multi-core and 1,681 single-core, which puts it in a competitive position for a budget chip. However, in Rust, the CPU's role is evident in the scaling pattern: at 1080p, the FPS difference between Low (201.4) and Ultra (123.3) is only 38.8%, while at 4K, the same settings difference is 59.4% (117 vs 47.6). This indicates that at 1080p, the CPU is the primary limiter, as the GPU cannot stretch its legs. The 4-core design with a 4.30 GHz boost is sufficient for Rust's engine, but the data shows that higher-core-count CPUs would likely improve 1080p performance, as the i3-12100F's 3DMark 8-thread score of 4,026 is only slightly lower than its 16-thread score of 4,051, suggesting diminishing returns beyond 8 threads.

Settings Recommendations

The measured data points to a clear sweet spot: 2560x1440 with High settings, delivering 114 FPS. This provides a 71.6% performance increase over 4K High (66.9 FPS) while maintaining visual quality. For players prioritizing frame rate over visuals, 1080p Low at 201.4 FPS is the maximum performance option, but it sacrifices the graphical fidelity that Rust's environment benefits from. At 4K, High settings (66.9 FPS) are the best choice for a playable experience, as Ultra drops to 47.6 FPS, which may feel sluggish in combat scenarios. The Medium preset at 1440p (133.8 FPS) offers a balanced alternative for those who want smoother motion without the visual compromises of Low. The data suggests avoiding Ultra at any resolution above 1080p — the FPS penalty is steep (from 123.3 at 1080p Ultra to 86.7 at 1440p Ultra, a 29.7% drop) and the visual gains are unlikely to justify it for a competitive survival game.

Measured FPS Breakdown

At 1920x1080, the combo delivers 201.4 FPS on Low, 172.4 FPS on Medium, 160 FPS on High, and 123.3 FPS on Ultra. The progression from Low to Ultra shows a 38.8% performance reduction, with the largest single drop occurring between High and Ultra (22.9%). Moving to 2560x1440, the frame rates are 178.3 FPS on Low, 133.8 FPS on Medium, 114 FPS on High, and 86.7 FPS on Ultra. The 1440p results show a similar pattern: Low to Medium drops 25.0%, Medium to High drops 14.8%, and High to Ultra drops 23.9%. At 3840x2160, the numbers fall to 117 FPS on Low, 78.9 FPS on Medium, 66.9 FPS on High, and 47.6 FPS on Ultra. The 4K scaling is steeper: Low to Medium drops 32.6%, Medium to High drops 15.2%, and High to Ultra drops 28.9%. Across all resolutions, the Low setting provides the highest headroom, suggesting that Rust's engine is more sensitive to settings changes at higher resolutions, where the GPU's workload increases exponentially. The 1080p Low result of 201.4 FPS is the highest recorded, while 4K Ultra at 47.6 FPS is the lowest, representing a 76.4% reduction in performance across the entire tested spectrum.
