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
Performance Report
At 1080p, all quality settings exceed 450 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 450 FPS. At 4K, all settings exceed 173 FPS.
The GeForce RTX 4090 is 611% above the recommended GPU (GeForce GTX 670) for Rainbow Six Siege. The EPYC 7351P is 277% above the recommended CPU (Core i5-2500K).
The EPYC 7351P determines the performance ceiling at 1080p low, 1440p (low/medium), all 4k settings, while the GPU has headroom. The system is well balanced at 1080p (medium/high/ultra), 1440p (high/ultra).
At 4k high, the EPYC 7351P sets the ceiling at about 195 FPS, while the GeForce RTX 4090 could reach 373 FPS. In this scenario, the CPU limits the GPU potential by 48% (FPS gap: 178 FPS). Overall distribution: CPU limits 7/12 cells, GPU limits 0/12, balanced 5/12.
Your EPYC 7351P 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 11% | Balanced | Balanced | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 20% | CPU Limits GPU 14% | Balanced | Balanced |
| 4K (Ultra HD) | CPU Limits GPU 47% | CPU Limits GPU 45% | CPU Limits GPU 48% | CPU Limits GPU 45% |
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 EPYC 7351P + GeForce RTX 4090 pairing runs this title with CPU utilization between 17% and 91% and GPU utilization between 28% and 78%. EPYC 7351P stays in a controlled operating range, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 55% at 1080p to 56% at 4K, while CPU averages move from 61% to 54%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 74% average at its highest-load preset, while the EPYC 7351P peaks at 82% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 61% and GPU 55%. At 1440p, that shifts to CPU 54% and GPU 56%, and at 4K it reaches CPU 54% and GPU 56%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
1080p (Full HD) High is the most balanced preset based on this dataset. It runs around CPU 40% (34-47%) and GPU 74% (72-75%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 7351P remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 7351P and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the EPYC 7351P paired with the GeForce RTX 4090 can run Rainbow Six Siege smoothly up to 4k achieving around 173 FPS at Ultra quality. Your GPU is 611% above the recommended specs, and your CPU is 277% above the recommended requirements.
Price data is not currently available for this combination. In general, look for setups where the CPU and GPU are balanced — this ensures you're not overspending on one component that the other can't keep up with.
For Rainbow Six Siege, upgrading the CPU would have the biggest impact on performance. The EPYC 7351P 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, 1440p low, 1440p medium, 4k low, 4k medium, 4k high, 4k ultra.
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 7351P 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.
