This tactical shooter uses the AnvilNext 2.0 engine and features procedural environmental destruction, which can be taxing on the CPU. The Vulkan API helps older hardware maintain performance by better utilizing available resources. Siege is sensitive to RAM speed and latency. The HD Texture Pack can push VRAM usage over 6GB, so cards with 8GB or more are recommended for the best visual experience at 1080p or 1440p.
Actual FPS may vary based on RAM speed, background processes, and other system factors

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1440p medium, the EPYC 4585PX sets the ceiling at about 523 FPS, while the GeForce RTX 4090 could reach 564 FPS. In this scenario, the CPU limits the GPU potential by 7% (FPS gap: 41 FPS). Overall distribution: CPU limits 1/12 cells, GPU limits 0/12, balanced 11/12. Confidence is low because both ceilings are very close in this cell.
The EPYC 4585PX 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 |
|---|---|---|---|---|
| 1080p (Full HD) | Balanced | Balanced | Balanced | Balanced |
| 1440p (2K QHD) | Balanced | CPU Limits GPU 7% | Balanced | Balanced |
| 4K (Ultra HD) | Balanced | 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, not generic utilization heuristics.

The EPYC 4585PX + GeForce RTX 4090 pairing runs this title with CPU utilization between 14% and 99% and GPU utilization between 22% and 85%. EPYC 4585PX reaches high load in heavier scenarios, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 56% at 1080p to 59% at 4K, while CPU averages move from 68% to 56%.
From a utilization perspective, this is a CPU-heavy load profile. At 1080p (Full HD) Low, the EPYC 4585PX reaches 94% average load (89-99%), while the GeForce RTX 4090 remains comparatively lower at 29% (22-36%). This points to heavier CPU-side frame preparation work, but utilization alone does not define the FPS limiter.
At 1080p, averages sit around CPU 68% and GPU 56%. At 1440p, that shifts to CPU 56% and GPU 59%, and at 4K it reaches CPU 56% and GPU 59%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
1440p (2K QHD) High is the most balanced preset based on this dataset. It runs around CPU 26% (14-39%) and GPU 84% (83-85%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 4585PX remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 4585PX and GeForce RTX 4090 remain reasonably matched for this title.
Understanding Hardware Utilization: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. They describe hardware load, but they do not directly tell you which component sets the FPS ceiling.
Important: a CPU or GPU can still be the FPS limiter without reaching 100% utilization. Two processors can both show 40% usage and still deliver very different frame rates, depending on per-core speed, cache, engine threading, driver overhead, and frame preparation efficiency.

Yes, the EPYC 4585PX paired with the GeForce RTX 4090 can run Rainbow Six Siege smoothly up to 4k achieving around 311 FPS at Ultra quality. Your GPU is 611% above the recommended specs, and your CPU is 970% above the recommended requirements.
This CPU + GPU combo costs approximately $2475 ($826 CPU (Rank #66 Value) + $1649 GPU (Rank #77 Value)). Your EPYC 4585PX 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 Threadripper PRO 9975WX is a great upgrade option for around $4099 (Rank #329 for value).
Your EPYC 4585PX 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 Rainbow Six Siege performance right now. CPU fully utilized at: 1440p medium.
Rainbow Six Siege 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.
Rainbow Six Siege requires at minimum a Core i3-560 (CPU) and GeForce GTX 460 (GPU) with 6 GB RAM and 61 GB storage. For the recommended experience, you need a Core i5-2500K and GeForce GTX 670 with 8 GB RAM. Your EPYC 4585PX and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Rainbow Six Siege 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.
