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, frame rates range from 2 to 5 FPS depending on quality settings. At 1440p, frame rates range from 2 to 4 FPS. At 4K, frame rates range from 1 to 2 FPS.
The GeForce9400M is 98% below minimum GPU requirement for Rust. The Ryzen 7 7800X3D is 180% above the recommended CPU (Core i7-4790K).
The GeForce9400M sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the Ryzen 7 7800X3D still has additional frame-generation headroom.
This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p ultra, the GeForce9400M sets the ceiling at about 2 FPS, while the Ryzen 7 7800X3D has headroom up to 168 FPS. In this scenario, the GPU limits the CPU potential by 99% (FPS gap: 166 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your GeForce9400M is the limiting side in the heaviest mismatch. This means part of the Ryzen 7 7800X3D frame-generation potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | GPU Limits CPU 98% | GPU Limits CPU 98% | GPU Limits CPU 98% | GPU Limits CPU 99% |
| 1440p (2K QHD) | GPU Limits CPU 98% | GPU Limits CPU 99% | GPU Limits CPU 99% | GPU Limits CPU 98% |
| 4K (Ultra HD) | GPU Limits CPU 99% | GPU Limits CPU 98% | GPU Limits CPU 98% | GPU Limits CPU 99% |
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, not generic utilization heuristics.

The Ryzen 7 7800X3D + GeForce9400M pairing runs this title with CPU utilization between 10% and 65% and GPU utilization between 62% and 100%. Ryzen 7 7800X3D keeps significant headroom across presets, while GeForce9400M carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 77% at 1080p to 93% at 4K, while CPU averages move from 28% to 26%.
From a utilization perspective, this is a GPU-heavy load profile. At 4K (Ultra HD) Low, the GeForce9400M averages 96% usage (92-100%), while the Ryzen 7 7800X3D stays at 22% (11-32%). This shows the graphics pipeline is carrying most of the workload, but utilization alone does not define the FPS limiter.
At 1080p, averages sit around CPU 28% and GPU 77%. At 1440p, that shifts to CPU 28% and GPU 77%, and at 4K it reaches CPU 26% and GPU 93%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) High is the most balanced preset based on this dataset. It runs around CPU 20% (10-31%) and GPU 90% (82-98%), which keeps GeForce9400M well utilized without constant max-out behavior while Ryzen 7 7800X3D remains stable for consistent frame delivery.
Upgrade priority should be the GPU. The GeForce9400M reaches 96% average load at 4K (Ultra HD) Low while the Ryzen 7 7800X3D still has headroom, so a faster graphics card would deliver the largest uplift.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

The Ryzen 7 7800X3D and GeForce9400M will struggle to run Rust at smooth framerates. At 1080p Ultra, you can expect around 2 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.
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 GeForce9400M is the limiting factor here, while the Ryzen 7 7800X3D 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 hardware falls below the minimum requirements for this game, which may result in poor 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.
