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 65 FPS. At 1440p, frame rates range from 49 to 91 FPS. At 4K, frame rates range from 18 to 42 FPS.
The RadeonT 780M is 36% below recommended, but 28% above minimum for Rust. The Ryzen 7 9800X3D is 226% above the recommended CPU (Core i7-4790K).
The RadeonT 780M sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Ryzen 7 9800X3D still has additional frame-generation headroom.
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 ultra, the RadeonT 780M sets the ceiling at about 23 FPS, while the Ryzen 7 9800X3D has headroom up to 91 FPS. In this scenario, the GPU limits the CPU potential by 75% (FPS gap: 68 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your RadeonT 780M is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 9800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 53% | GPU Limits CPU 53% | GPU Limits CPU 56% | GPU Limits CPU 59% |
| 1440p (2K QHD) | GPU Limits CPU 57% | GPU Limits CPU 57% | GPU Limits CPU 60% | GPU Limits CPU 60% |
| 4K (Ultra HD) | GPU Limits CPU 68% | GPU Limits CPU 68% | GPU Limits CPU 71% | GPU Limits CPU 75% |
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 226% below recommended and your GPU is 36% below recommended, but both meet minimum specs. Playable at Low/Medium settings, 1080p or below.

Yes, the Ryzen 7 9800X3D paired with the RadeonT 780M can run Rust smoothly up to 1080p achieving around 65 FPS at Ultra quality. Your GPU is 36% below the recommended specs, and your CPU is 226% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For Rust, upgrading the GPU would give you the most noticeable improvement. The RadeonT 780M is the limiting factor here, while the Ryzen 7 9800X3D 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 setup meets the minimum requirements but falls short of the recommended specs. You may need to lower some settings for smooth performance.
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.
