Fortnite serves as a showcase for Unreal Engine 5. In 'Performance Mode', it runs on almost anything. However, enabling 'Lumen' (global illumination) and 'Nanite' (virtualized geometry) requires a powerful RTX 30/40 series GPU to maintain 60 FPS. The building mechanics also add a significant CPU load, especially in competitive end-games with dense player structures.
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 87 FPS. At 1440p, all settings exceed 67 FPS. At 4K, frame rates range from 41 to 78 FPS.
The GeForce RTX 4090 is 136% above the recommended GPU (GeForce GTX 1080) for Fortnite. The EPYC 7351P is 89% above the recommended CPU (Core i5-7300U).
The EPYC 7351P determines the performance ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GPU has headroom.
At 1080p low, the EPYC 7351P sets the ceiling at about 237 FPS, while the GeForce RTX 4090 could reach 543 FPS. In this scenario, the CPU limits the GPU potential by 56% (FPS gap: 306 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
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 56% | CPU Limits GPU 49% | CPU Limits GPU 43% | CPU Limits GPU 52% |
| 1440p (2K QHD) | CPU Limits GPU 55% | CPU Limits GPU 48% | CPU Limits GPU 51% | CPU Limits GPU 48% |
| 4K (Ultra HD) | CPU Limits GPU 55% | CPU Limits GPU 44% | CPU Limits GPU 53% | CPU Limits GPU 46% |
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 39% and 83% and GPU utilization between 34% and 100%. EPYC 7351P stays in a controlled operating range, while GeForce RTX 4090 becomes the primary limiter at high visual load. As resolution scales, average GPU load rises from 73% at 1080p to 85% at 4K, while CPU averages move from 63% to 61%.
This profile is GPU-bound. At 4K (Ultra HD) High, the GeForce RTX 4090 averages 100% usage (99-100%), while the EPYC 7351P stays at 52% (39-64%), indicating the graphics pipeline is the limiting stage.
At 1080p, averages sit around CPU 63% and GPU 73%. At 1440p, that shifts to CPU 62% and GPU 83%, and at 4K it reaches CPU 61% and GPU 85%. This shows that GPU demand scales sharply with resolution while CPU load remains comparatively stable.
4K (Ultra HD) Medium is the most balanced preset based on this dataset. It runs around CPU 68% (61-76%) and GPU 88% (77-99%), 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.
Understanding Hardware Utilization & Bottlenecks: These percentages represent how much of your component's maximum processing power is actively being used during gameplay. This is the key to identifying performance bottlenecks in any system.

Yes, the EPYC 7351P paired with the GeForce RTX 4090 can run Fortnite smoothly up to 1440p achieving around 67 FPS at Ultra quality. Your GPU is 136% above the recommended specs, and your CPU is 89% 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 Fortnite, 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, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
Fortnite 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.
Fortnite requires at minimum a Core i3-3225 (CPU) and GeForce GTX 960 (GPU) with 8 GB RAM and 30 GB storage. For the recommended experience, you need a Core i5-7300U and GeForce GTX 1080 with 16 GB RAM. Your EPYC 7351P and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Fortnite 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.
