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 107 FPS. At 1440p, all settings exceed 75 FPS. At 4K, frame rates range from 29 to 53 FPS.
The GeForce RTX 4090 is 244% above the recommended GPU (GeForce GTX 980) for Rust. The Xeon Gold 5317 is 124% above the recommended CPU (Core i7-4790K).
The Xeon Gold 5317 determines the performance ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GPU has headroom.
Approximated average price on current market:
Combo price: $2749. At 1080p Ultra, this combo delivers 107 FPS, equivalent to 0.04 FPS per dollar.

At 4k medium, the Xeon Gold 5317 sets the ceiling at about 46 FPS, while the GeForce RTX 4090 could reach 130 FPS. In this scenario, the CPU limits the GPU potential by 65% (FPS gap: 84 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Xeon Gold 5317 is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 36% | CPU Limits GPU 34% | CPU Limits GPU 28% | CPU Limits GPU 35% |
| 1440p (2K QHD) | CPU Limits GPU 46% | CPU Limits GPU 48% | CPU Limits GPU 41% | CPU Limits GPU 40% |
| 4K (Ultra HD) | CPU Limits GPU 62% | CPU Limits GPU 65% | CPU Limits GPU 63% | CPU Limits GPU 65% |
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.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

Yes, the Xeon Gold 5317 paired with the GeForce RTX 4090 can run Rust smoothly up to 1440p achieving around 75 FPS at Ultra quality. Your GPU is 244% above the recommended specs, and your CPU is 124% above the recommended requirements.
This CPU + GPU combo costs approximately $2749 ($1100 CPU (Rank #333 Value) + $1649 GPU (Rank #77 Value)). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Xeon Platinum 8454H is a great upgrade option for around $6540 (Rank #1 for value).
For Rust, upgrading the CPU would have the biggest impact on performance. The Xeon Gold 5317 is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-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 Xeon Gold 5317 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.
