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 163 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 140 FPS. At 4K, all settings exceed 98 FPS.
The GeForce RTX 4090 is 244% above the recommended GPU (GeForce GTX 980) for Rust. The Core i7-14701E is 113% above the recommended CPU (Core i7-4790K).
Rust supports: AFMF. This game does not have native DLSS 3 or FSR 3 Frame Generation support. AFMF is AMD-exclusive and not compatible with GeForce RTX 4090.
No major FPS-ceiling mismatch detected. The GeForce RTX 4090 and Core i7-14701E stay close in effective frame-generation ceiling across the tested resolutions and quality settings.
Approximated average price on current market:
Combo price: $2029. At 1080p Ultra, this combo delivers 163 FPS, equivalent to 0.08 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1440p high, the GeForce RTX 4090 sets the ceiling at about 156 FPS, while the Core i7-14701E has headroom up to 166 FPS. In this scenario, the GPU limits the CPU potential by 6% (FPS gap: 10 FPS). Overall distribution: GPU limits 1/12 cells, CPU limits 0/12, balanced 11/12. Confidence is low because both ceilings are very close in this cell.
The Core i7-14701E and GeForce RTX 4090 stay close in effective frame-generation ceiling across most presets, so neither side consistently suppresses the other by a large margin.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | Balanced | Balanced | Balanced | Balanced |
| 1440p (2K QHD) | Balanced | Balanced | GPU Limits CPU 6% | Balanced |
| 4K (Ultra HD) | Balanced | Balanced | Balanced | Balanced |
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.

Yes, the Core i7-14701E paired with the GeForce RTX 4090 can run Rust smoothly up to 4k achieving around 98 FPS at Ultra quality. Your GPU is 244% above the recommended specs, and your CPU is 113% above the recommended requirements.
This CPU + GPU combo costs approximately $2029 ($380 CPU (Rank #284 Value) + $1649 GPU (Rank #77 Value)). This is a well-balanced setup, meaning you're getting good value from both components without significant waste.
This setup is already well-balanced for Rust. No significant bottleneck - CPU and GPU are well matched across all settings. Both the Core i7-14701E and GeForce RTX 4090 complement each other effectively, so upgrading either component individually would yield diminishing returns. If you want more FPS, you'd benefit most from upgrading both CPU and GPU together.
Rust currently only supports AFMF (AMD Fluid Motion Frames) for frame generation, which is an AMD-exclusive technology. Because you are using an NVIDIA GPU, you cannot use Frame Generation for this specific game. However, the game does support DLSS Upscaling and FSR Upscaling, which you should enable to render at a lower resolution and use AI to significantly boost your FPS without losing visual quality.
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 i7-14701E and GeForce RTX 4090 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.
