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

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k low, the Radeon Pro W6900X sets the ceiling at about 69 FPS, while the Ryzen 7 7800X3D has headroom up to 145 FPS. In this scenario, the GPU limits the CPU potential by 52% (FPS gap: 76 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your Radeon Pro W6900X 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 20% | GPU Limits CPU 21% | GPU Limits CPU 20% | GPU Limits CPU 16% |
| 1440p (2K QHD) | GPU Limits CPU 37% | GPU Limits CPU 39% | GPU Limits CPU 31% | GPU Limits CPU 30% |
| 4K (Ultra HD) | GPU Limits CPU 52% | GPU Limits CPU 52% | GPU Limits CPU 46% | GPU Limits CPU 45% |
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 + Radeon Pro W6900X pairing runs this title with CPU utilization between 10% and 67% and GPU utilization between 53% and 99%. Ryzen 7 7800X3D keeps significant headroom across presets, while Radeon Pro W6900X carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 68% at 1080p to 91% at 4K, while CPU averages move from 28% to 27%.
From a utilization perspective, this is a GPU-heavy load profile. At 4K (Ultra HD) High, the Radeon Pro W6900X averages 91% usage (83-99%), while the Ryzen 7 7800X3D stays at 21% (10-32%). 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 68%. At 1440p, that shifts to CPU 29% and GPU 68%, and at 4K it reaches CPU 27% and GPU 91%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) Low is the most balanced preset based on this dataset. It runs around CPU 22% (10-34%) and GPU 90% (87-93%), which keeps Radeon Pro W6900X well utilized without constant max-out behavior while Ryzen 7 7800X3D remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 7 7800X3D and Radeon Pro W6900X remain reasonably matched for this title.
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.

Yes, the Ryzen 7 7800X3D paired with the Radeon Pro W6900X can run Rust smoothly up to 1440p achieving around 94 FPS at Ultra quality. Your GPU is 57% above the recommended specs, and your CPU is 180% above the recommended requirements.
This CPU + GPU combo costs approximately $5384 ($384 CPU (Rank #212 Value) + $5000 GPU (Rank #104 Value)). Your Radeon Pro W6900X is currently the main performance bottleneck and its market value ($5000) is actually higher than newer, faster alternatives. Trading it or upgrading could yield immediate profit and performance gains. For example, upgrading to the RTX PRO 4500 Blackwell for around $2399 (Rank #51 for value) could deliver noticeably better performance while costing less than your current GPU.
For Rust, upgrading the GPU would give you the most noticeable improvement. The Radeon Pro W6900X 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 Ryzen 7 7800X3D and Radeon Pro W6900X 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.
