Rust

The data for Rust with the Intel Core i3-12100F and NVIDIA GeForce RTX 5090 reveals a configuration where the CPU consistently limits performance, particularly at lower resolutions. The measured average frame rates across 1080p, 1440p, and 4K with varying presets show a clear pattern of GPU headroom being left on the table. This analysis breaks down the scaling behavior, the combo’s standing in the database, and the implications of pairing a high-end graphics card with a quad-core processor.

Resolution Scaling

The frame rate progression from 1080p to 4K clearly identifies the Intel Core i3-12100F as the primary constraint in this pairing. At 1080p with the High preset, the combo delivers 164.8 FPS. Moving to 1440p High drops the average to 126.4 FPS, a reduction of 38.4 FPS. The further step to 4K High yields 78.2 FPS, which is 86.6 FPS below the 1080p figure. This steep decline at higher resolutions suggests that while the GPU is taking on more work, the CPU’s four cores are still dictating the ceiling for how many frames can be processed.

The scaling pattern becomes even more telling when examining the Low preset. At 1080p Low, the system reaches 199 FPS, the highest number in the entire dataset. At 1440p Low, it falls to 176.9 FPS, and at 4K Low, it drops to 132.2 FPS. The difference between 1080p and 1440p Low is only 22.1 FPS, which is a relatively modest decline compared to the 44.7 FPS gap between 1440p and 4K Low. This indicates that at lower resolutions, the CPU is almost certainly saturating its capabilities. The RTX 5090, with its 32 GB of GDDR7 memory and 1.79 TB/s bandwidth, is not being fully utilized when the resolution is low enough for the CPU to keep up with the render requests.

The Ultra preset shows the most significant scaling drop. The system produces 142 FPS at 1080p Ultra, 98.5 FPS at 1440p Ultra, and only 61.2 FPS at 4K Ultra. The gap between 1080p and 1440p Ultra is 43.5 FPS, while the gap between 1440p and 4K Ultra is 37.3 FPS. This behavior is characteristic of a system where the GPU is increasingly burdened at higher resolutions, but the CPU’s single-thread performance, as evidenced by its 3dmark_single_thread score of 893, is still the limiting factor for peak frame generation.

How This Combo Ranks

This specific combination of the Intel Core i3-12100F and NVIDIA GeForce RTX 5090 ranks 58th out of 1717 tested combos in Rust. That places it in the top 3.4% of all configurations in the database, which is a strong overall position. However, the ranking is heavily influenced by the GPU’s raw power, which can brute-force through many scenes. The CPU’s percentile ranking against all processors is 72, indicating it is better than 72% of CPUs tested. The GPU, on the other hand, sits at the 94th percentile against all GPUs.

The deltaPct values for the CPU’s nearest rivals show how close the i3-12100F is to other processors in average benchmark score. The AMD Ryzen Threadripper PRO 3975WX has an average score of 13534, which is 0.1% higher than the i3-12100F’s 13516. The Intel Core i7-1250U scores 13462, putting it 0.4% behind, and the Intel Core i3-10105 scores 13430, a 0.6% deficit. The Intel Core i7-7700K is 1.8% lower with a score of 13280. These margins are tiny, showing that the i3-12100F is firmly in a competitive bracket for its average computational throughput, even though its four cores and eight threads limit its peak multithreaded performance in games that can scale beyond that.

Given the GPU’s high rank, the 58th position for this combo is likely lower than what the RTX 5090 could achieve with a more capable processor. The data strongly suggests that the combo’s rank is dragged down by the CPU’s inability to feed the GPU enough frames at lower resolutions, where the CPU’s limitations are most exposed.

GPU Role

The NVIDIA GeForce RTX 5090 is a Blackwell 2.0 architecture part built on a 5 nm process at TSMC. It features 32 GB of GDDR7 memory on a 512-bit bus, yielding a bandwidth of 1.79 TB/s. The GPU’s base clock is 2017 MHz with a boost clock of 2407 MHz. These specifications are relevant to Rust because the game’s large, persistent world and frequent asset streaming can benefit from high memory capacity and bandwidth. The 32 GB frame buffer is far beyond what the game currently requires, and the memory bandwidth is sufficient to handle any texture streaming load without issue.

The GPU’s benchmark scores reinforce its high-end status. It achieves a 3dmark_steel_nomad_dx12 score of 14411 and a geekbench_opencl score of 380114. Its passmark_g3d score is 39650, placing it in the 94th percentile of all GPUs. The nearest rival is the NVIDIA GeForce RTX 5090 D with an average score of 84241, a 0.1% difference. The NVIDIA GeForce RTX 5050 Mobile is 0.2% behind at 84171, and the AMD Radeon PRO W6600 is 1.3% lower at 83209. The NVIDIA CMP 40HX is 1.6% higher at 85637. These rival comparisons show that the RTX 5090 is at the absolute top of the performance stack.

In this specific Rust configuration, the GPU is largely underutilized. The measured frame rates at 1080p with any preset do not reflect the GPU’s peak capability. The GPU’s high pixel rate of 423.6 GPixel/s and texture rate of 1,636.8 GTexel/s are not being fully exercised because the CPU cannot issue draw calls fast enough. The GPU is waiting on the CPU to provide instructions, which is a classic bottleneck scenario.

Settings Recommendations

The measured data provides a clear hierarchy for settings presets at each resolution. At 1080p, the Low preset yields 199 FPS, which is the highest achievable average. The Medium preset delivers 174.9 FPS, and the High preset gives 164.8 FPS. The Ultra preset at 1080p produces 142 FPS. Since the CPU is the bottleneck, moving from Low to Ultra only reduces the frame rate, but the visual quality improvements from Ultra may be desirable for some users. However, the data shows that the jump from High to Ultra costs 22.8 FPS, which is a substantial hit for settings that may not provide a proportional visual benefit in a survival game where visibility and reaction time are critical.

At 1440p, the Medium preset stands out as a strong option. It delivers 152.7 FPS, which is 26.3 FPS higher than the High preset’s 126.4 FPS. The Low preset at 1440p gives 176.9 FPS, but the Medium preset offers a significant improvement in visual fidelity over Low while still maintaining a frame rate well above 144 Hz. The Ultra preset at 1440p drops to 98.5 FPS, which is playable but not ideal for high-refresh-rate monitors.

At 4K, the trade-offs are more pronounced. The Low preset achieves 132.2 FPS, which is excellent for 4K. The Medium preset drops to 89.2 FPS, and the High preset falls to 78.2 FPS. The Ultra preset at 4K yields 61.2 FPS, which is the lowest measured value in the entire dataset. For a smooth 4K experience, the Medium preset appears to be the best balance, offering a 60+ FPS experience with better visuals than Low. The High preset is also viable if the user prefers higher quality over frame rate, but the gap between High and Medium is only 11 FPS, while the visual difference is often minimal in fast-paced scenes.
