Rust
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 115 FPS. At 1440p, all settings exceed 89 FPS. At 4K, frame rates range from 36 to 81 FPS.
The GeForce RTX 4090 is 244% above the recommended GPU (GeForce GTX 980) for Rust. The EPYC 7H12 is 468% above the recommended CPU (Core i7-4790K).
The EPYC 7H12 sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GeForce RTX 4090 still has headroom.
Approximated average price on current market:
Combo price: $2989. At 1080p Ultra, this combo delivers 115 FPS, equivalent to 0.04 FPS per dollar.

This chart answers a simple question: which upgrade is more likely to increase FPS first? In this case, the answer is clearly the CPU.
The largest gap appears at 1080p Low, where the EPYC 7H12 reaches about 187 FPS, while the GeForce RTX 4090 still has headroom up to roughly 336 FPS.
That means the EPYC 7H12 is hitting its performance ceiling first, leaving a 44% gap versus the GeForce RTX 4090's available headroom in the most unbalanced scenario. Across all tested settings, this pairing is CPU-limited in 12 out of 12 cases, with 0 GPU-limited and 0 balanced results.
Overall, this is a clearly CPU-bound combination in this game.
The EPYC 7H12 is consistently the limiting part in this game, so upgrading the CPU is more likely to deliver a larger FPS gain than upgrading the GPU.
This chart shows which upgrade is more likely to unlock more FPS in each tested setting. The lower line represents the part that reaches its limit first. When the CPU and GPU lines stay close together, the system is more balanced. When the gap widens, one component is more clearly holding the other back. Hover any setting to inspect it.
The lower line is the current limiter. The closer the two lines are, the more balanced the CPU and GPU are for this game.
Each line represents an estimated FPS ceiling for one component, rather than live usage alone.
To estimate the CPU ceiling, we pair the EPYC 7H12 with GeForce RTX 5090, our current GPU anchor. To estimate the GPU ceiling, we pair the GeForce RTX 4090 with Ryzen 9 9950X3D, our current CPU anchor.
The lower line indicates the current limiter, since that component reaches its FPS ceiling first. In most scenarios, that is also the part most likely to deliver the bigger performance uplift if upgraded first.
The percentage shown represents the gap between the two ceilings. In practical terms, it shows how much of the stronger component's potential is left unused because the weaker one becomes the bottleneck first.

Yes, the EPYC 7H12 paired with the GeForce RTX 4090 can run Rust smoothly up to 1440p achieving around 89 FPS at Ultra quality. Your GPU is 244% above the recommended specs, and your CPU is 468% above the recommended requirements.
This CPU + GPU combo costs approximately $2,989 ($1,340 CPU + $1,649 GPU). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the EPYC 9375F is a great upgrade option for around $5,306 (Rank #5 for value).
For Rust, upgrading the CPU would usually improve performance first. In the Performance Limiter Analysis, the EPYC 7H12 is the side that most often caps the frame rate, while the GeForce RTX 4090 still has additional headroom in the tested presets. If you want to move closer to the current market ceiling, a stronger processor like Ryzen Threadripper PRO 9995WX for around $11,699 would be the clearest next step. The main bottleneck appears on the CPU side. The largest gap shows up at 1080p Low, where the CPU reaches about 187 FPS while the GPU still has headroom up to roughly 336 FPS. Across all tested settings, the distribution is 0/12 GPU-limited, 12/12 CPU-limited, and 0/12 balanced.
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 7H12 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.
