At 4k low, the GeForce RTX 4090 sets the ceiling at about 147 FPS, while the Ryzen Threadripper 7970X has headroom up to 158 FPS. In this scenario, the GPU limits the CPU potential by 7% (FPS gap: 11 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 Ryzen Threadripper 7970X 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 |

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.

The Ryzen Threadripper 7970X + GeForce RTX 4090 pairing runs this title with CPU utilization between 11% and 53% and GPU utilization between 87% and 100%. Ryzen Threadripper 7970X keeps significant headroom across presets, while GeForce RTX 4090 becomes the primary limiter at high visual load. As resolution scales, average GPU load rises from 97% at 1080p to 98% at 4K, while CPU averages move from 30% to 24%.
This profile is GPU-bound. At 1080p (Full HD) High, the GeForce RTX 4090 averages 100% usage (100-100%), while the Ryzen Threadripper 7970X stays at 26% (17-34%), indicating the graphics pipeline is the limiting stage.
At 1080p, averages sit around CPU 30% and GPU 97%. At 1440p, that shifts to CPU 30% and GPU 97%, and at 4K it reaches CPU 24% and GPU 98%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
1080p (Full HD) Low is the most balanced preset based on this dataset. It runs around CPU 26% (18-35%) and GPU 94% (87-100%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen Threadripper 7970X remains stable for consistent frame delivery.
Upgrade priority should be the GPU. The GeForce RTX 4090 reaches 100% average load at 1080p (Full HD) High while the Ryzen Threadripper 7970X still has headroom, so a faster graphics card would deliver the largest uplift.

Yes, the Ryzen Threadripper 7970X paired with the GeForce RTX 4090 can run Rust smoothly up to 4k achieving around 92 FPS at Ultra quality. Your GPU is 244% above the recommended specs, and your CPU is 709% above the recommended requirements.
This CPU + GPU combo costs approximately $3849 ($2200 CPU (Rank #354 Value) + $1649 GPU (Rank #77 Value)). Your GeForce RTX 4090 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 card with a significantly better value rating.
Your GeForce RTX 4090 is already a top-tier graphics card. While it's technically the limiting factor here (which means you are fully utilizing your GPU's visual horsepower exactly as intended), there is no meaningful upgrade path that would drastically improve your Rust performance right now. GPU fully utilized at: 4k low.
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 Ryzen Threadripper 7970X 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.
