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 21 to 36 FPS depending on quality settings. At 1440p, frame rates range from 13 to 20 FPS. At 4K, frame rates range from 5 to 10 FPS.
The Radeon R7 384 Cores (Kaveri Desktop) is 82% below minimum GPU requirement for Rust. The Ryzen 7 7800X3D is 180% above the recommended CPU (Core i7-4790K).
The Radeon R7 384 Cores (Kaveri Desktop) 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.
Approximated average price on current market:
Combo price: $433. At 1080p Ultra, this combo delivers 21 FPS, equivalent to 0.05 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p ultra, the Radeon R7 384 Cores (Kaveri Desktop) sets the ceiling at about 22 FPS, while the Ryzen 7 7800X3D has headroom up to 90 FPS. In this scenario, the GPU limits the CPU potential by 76% (FPS gap: 68 FPS). Overall distribution: GPU limits 12/12 cells, CPU limits 0/12, balanced 0/12.
Your Radeon R7 384 Cores (Kaveri Desktop) 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 69% | GPU Limits CPU 75% | GPU Limits CPU 75% | GPU Limits CPU 76% |
| 1440p (2K QHD) | GPU Limits CPU 71% | GPU Limits CPU 75% | GPU Limits CPU 73% | GPU Limits CPU 73% |
| 4K (Ultra HD) | GPU Limits CPU 58% | GPU Limits CPU 61% | GPU Limits CPU 62% | GPU Limits CPU 61% |
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 and Radeon R7 384 Cores (Kaveri Desktop) will struggle to run Rust at smooth framerates. At 1080p Ultra, you can expect around 21 FPS which is classified as "struggling". Consider lowering settings or upgrading your hardware.
This CPU + GPU combo costs approximately $433 ($384 CPU + $49 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 5060 for around $299 (Rank #2 for value) could deliver noticeably better performance.
For Rust, upgrading the GPU would give you the most noticeable improvement. The Radeon R7 384 Cores (Kaveri Desktop) 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.
