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 89 FPS. At 1440p, all settings exceed 66 FPS. At 4K, frame rates range from 28 to 49 FPS.
The GeForce RTX 4090 is 244% above the recommended GPU (GeForce GTX 980) for Rust. The EPYC 8324P is 366% above the recommended CPU (Core i7-4790K).
The EPYC 8324P 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: $5247. At 1080p Ultra, this combo delivers 89 FPS, equivalent to 0.02 FPS per dollar.

At 4k medium, the EPYC 8324P sets the ceiling at about 41 FPS, while the GeForce RTX 4090 could reach 135 FPS. In this scenario, the CPU limits the GPU potential by 70% (FPS gap: 94 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your EPYC 8324P 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 44% | CPU Limits GPU 47% | CPU Limits GPU 44% | CPU Limits GPU 46% |
| 1440p (2K QHD) | CPU Limits GPU 53% | CPU Limits GPU 56% | CPU Limits GPU 52% | CPU Limits GPU 50% |
| 4K (Ultra HD) | CPU Limits GPU 67% | CPU Limits GPU 70% | CPU Limits GPU 69% | CPU Limits GPU 68% |
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 EPYC 8324P paired with the GeForce RTX 4090 can run Rust smoothly up to 1440p achieving around 66 FPS at Ultra quality. Your GPU is 244% above the recommended specs, and your CPU is 366% above the recommended requirements.
This CPU + GPU combo costs approximately $5247 ($3598 CPU (Rank #301 Value) + $1649 GPU (Rank #77 Value)). Your EPYC 8324P 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 EPYC 9355P is a great upgrade option for around $2998 (Rank #287 for value) while costing less than your current CPU.
Your EPYC 8324P 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: 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 EPYC 8324P 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.
