A true test for system memory. Procedural maps can exhaust RAM quickly; 16GB is the minimum, and 32GB is recommended. CPUs with 3D V-Cache (AMD X3D) offer massive performance gains here.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 135 FPS. At 1440p, all settings exceed 109 FPS. At 4K, frame rates range from 55 to 95 FPS.
The GeForce RTX 3070 is 100% above the recommended GPU (GeForce GTX 980) for Rust. The Core i5-12600K is 125% above the recommended CPU (Core i7-4790K).
The GeForce RTX 3070 sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Core i5-12600K still has additional frame-generation headroom.
Approximated average price on current market:
Combo price: $385. At 1080p Ultra, this combo delivers 135 FPS, equivalent to 0.35 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages. Adjacent heavier settings are lightly stabilized to remove prediction jitter that would otherwise create impossible reversals.
At 4k low, the GeForce RTX 3070 sets the ceiling at about 113 FPS, while the Core i5-12600K has headroom up to 183 FPS. In this scenario, the GPU limits the CPU potential by 38% (FPS gap: 70 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your GeForce RTX 3070 is the limiting side in the heaviest mismatch. This means part of the Core i5-12600K frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 29% | GPU Limits CPU 29% | GPU Limits CPU 29% | GPU Limits CPU 29% |
| 1440p (2K QHD) | GPU Limits CPU 30% | GPU Limits CPU 30% | GPU Limits CPU 30% | GPU Limits CPU 30% |
| 4K (Ultra HD) | GPU Limits CPU 38% | GPU Limits CPU 38% | GPU Limits CPU 38% | GPU Limits CPU 38% |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings and then monotonic-smoothed across heavier presets and resolutions, not generic utilization heuristics.
See how your processor and graphics card compare against the game official minimum and recommended system specs. The placement of your hardware is calculated using relative synthetic performance scores to help you gauge overall playability.
Your CPU is 125% above and your GPU is 100% above the recommended specs. Ultra settings at 1080p, or High at 1440p/4K.

Yes, the Core i5-12600K paired with the GeForce RTX 3070 can run Rust smoothly up to 1440p achieving around 109 FPS at Ultra quality. Your GPU is 100% above the recommended specs, and your CPU is 125% above the recommended requirements.
This CPU + GPU combo costs approximately $385 ($185 CPU + $200 GPU). Since the GPU is the main limiting factor, investing in a stronger GPU will improve your framerates and overall value. For example, upgrading to the GeForce RTX 4070 Ti for around $799 (Rank #248 for value) could deliver noticeably better performance.
For Rust, upgrading the GPU would give you the most noticeable improvement. The GeForce RTX 3070 is the limiting factor here, while the Core i5-12600K still has spare capacity. A more powerful GPU would unlock higher FPS, especially at higher resolutions and quality presets. GPU-limited at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
Rust does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
Rust requires at minimum a Core i7-3770 (CPU) and GeForce GTX 670 (GPU) with 10 GB RAM and 25 GB (SSD) storage. For the recommended experience, you need a Core i7-4790K and GeForce GTX 980 with 16 GB RAM. Your Core i5-12600K and GeForce RTX 3070 both exceed the recommended specs, so you're well-positioned for a great experience.
These Rust FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
