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 184 FPS, suitable for 144Hz+ monitors. At 1440p, all settings exceed 130 FPS. At 4K, all settings exceed 75 FPS.
The GeForce RTX 4090 is 136% above the recommended GPU (GeForce GTX 1080) for Fortnite. The Xeon w5-2555X is 262% above the recommended CPU (Core i5-7300U).
At lower resolutions (1440p (low/ultra), 4k (low/medium/high)), the Xeon w5-2555X sets the FPS ceiling. As graphical load increases at (1080p (medium/high)), the GeForce RTX 4090 becomes the FPS-limiting side. The FPS ceiling is closely matched at 1080p (low/ultra), 1440p (medium/high), 4k ultra.
Approximated average price on current market:
Combo price: $2794. At 1080p Ultra, this combo delivers 184 FPS, equivalent to 0.07 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1080p medium, the GeForce RTX 4090 sets the ceiling at about 391 FPS, while the Xeon w5-2555X has headroom up to 448 FPS. In this scenario, the GPU limits the CPU potential by 13% (FPS gap: 57 FPS). Overall distribution: GPU limits 2/12 cells, CPU limits 5/12, balanced 5/12.
The Xeon w5-2555X 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 | GPU Limits CPU 13% | GPU Limits CPU 12% | Balanced |
| 1440p (2K QHD) | CPU Limits GPU 9% | Balanced | Balanced | CPU Limits GPU 12% |
| 4K (Ultra HD) | CPU Limits GPU 13% | CPU Limits GPU 8% | CPU Limits GPU 8% | 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 Xeon w5-2555X + GeForce RTX 4090 pairing runs this title with CPU utilization between 20% and 95% and GPU utilization between 31% and 100%. Xeon w5-2555X stays in a controlled operating range, while GeForce RTX 4090 carries most of the graphics load at heavier visual settings. As resolution scales, average GPU load rises from 73% at 1080p to 84% at 4K, while CPU averages move from 59% to 46%.
From a utilization perspective, this is a GPU-heavy load profile. At 4K (Ultra HD) High, the GeForce RTX 4090 averages 99% usage (98-100%), while the Xeon w5-2555X stays at 32% (20-45%). This shows the graphics pipeline is carrying most of the workload, but utilization alone does not define the FPS limiter.
At 1080p, averages sit around CPU 59% and GPU 73%. At 1440p, that shifts to CPU 49% and GPU 83%, and at 4K it reaches CPU 46% and GPU 84%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
1080p (Full HD) Ultra is the most balanced preset based on this dataset. It runs around CPU 42% (27-56%) and GPU 87% (78-96%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Xeon w5-2555X remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Xeon w5-2555X 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 Xeon w5-2555X paired with the GeForce RTX 4090 can run Fortnite smoothly up to 4k achieving around 75 FPS at Ultra quality. Your GPU is 136% above the recommended specs, and your CPU is 262% above the recommended requirements.
This CPU + GPU combo costs approximately $2794 ($1145 CPU (Rank #241 Value) + $1649 GPU (Rank #77 Value)). Your Xeon w5-2555X 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 EPYC 4585PX is a great upgrade option for around $699 (Rank #66 for value) while costing less than your current CPU.
Your Xeon w5-2555X 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 Fortnite performance right now. CPU fully utilized at: 1440p low, 1440p ultra, 4k low, 4k medium, 4k high. GPU fully utilized at: 1080p medium, 1080p high.
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 Xeon w5-2555X 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.
