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 182 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 159 FPS. At 4K, all settings exceed 82 FPS.
The GeForce RTX 5090 is 251% above the recommended GPU (GeForce GTX 980) for Rust. The Core i9-14900HX is 264% above the recommended CPU (Core i7-4790K).
The Core i9-14900HX sets the FPS ceiling at all 1440p settings, all 4k settings, while the GeForce RTX 5090 still has headroom. The FPS ceiling is closely matched at all 1080p settings.
Approximated average price on current market:
Combo price: $2849. At 1080p Ultra, this combo delivers 182 FPS, equivalent to 0.06 FPS per dollar.

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 1080p low, the Core i9-14900HX sets the ceiling at about 346 FPS, while the GeForce RTX 5090 could reach 367 FPS. In this scenario, the CPU limits the GPU potential by 6% (FPS gap: 21 FPS). Overall distribution: CPU limits 3/12 cells, GPU limits 0/12, balanced 9/12. Confidence is low because both ceilings are very close in this cell.
The Core i9-14900HX and GeForce RTX 5090 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) | CPU Limits GPU 6% | Balanced | Balanced | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 6% | Balanced | Balanced | Balanced |
| 4K (Ultra HD) | CPU Limits GPU 6% | 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 and then monotonic-smoothed across heavier presets and resolutions, not generic utilization heuristics.

Yes, the Core i9-14900HX paired with the GeForce RTX 5090 can run Rust smoothly up to 4k achieving around 82 FPS at Ultra quality. Your GPU is 251% above the recommended specs, and your CPU is 264% above the recommended requirements.
This CPU + GPU combo costs approximately $2849 ($149 CPU + $2700 GPU). Your Core i9-14900HX provides phenomenal top-tier performance but at a premium enthusiast price. Since you are essentially at the ceiling of current hardware capabilities, there are no meaningful performance upgrades available. However, if you wanted a more cost-effective build that still delivers a great experience, you could theoretically step down to a high-end processor with a significantly better value rating. For example, the Ryzen 9 9955HX3D is a great upgrade option for around $749 (Rank #109 for value).
Your Core i9-14900HX is already an incredibly powerful processor. While it's technically the first component to hit its limit (which is completely normal in state-of-the-art builds), there is no meaningful upgrade path that would drastically improve your Rust performance right now. CPU fully utilized at: 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 Core i9-14900HX and GeForce RTX 5090 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.
