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

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 1440p low, the Xeon Gold 6438Y+ sets the ceiling at about 135 FPS, while the GeForce RTX 4090 could reach 314 FPS. In this scenario, the CPU limits the GPU potential by 57% (FPS gap: 179 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Xeon Gold 6438Y+ 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 51% | CPU Limits GPU 42% | CPU Limits GPU 37% | CPU Limits GPU 48% |
| 1440p (2K QHD) | CPU Limits GPU 57% | CPU Limits GPU 50% | CPU Limits GPU 54% | CPU Limits GPU 52% |
| 4K (Ultra HD) | CPU Limits GPU 57% | CPU Limits GPU 46% | CPU Limits GPU 54% | 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.
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 Gold 6438Y+ + GeForce RTX 4090 pairing runs this title with CPU utilization between 35% and 82% and GPU utilization between 34% and 100%. Xeon Gold 6438Y+ 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 72% at 1080p to 86% at 4K, while CPU averages move from 62% to 53%.
From a utilization perspective, this is a GPU-heavy load profile. At 4K (Ultra HD) High, the GeForce RTX 4090 averages 100% usage (100-100%), while the Xeon Gold 6438Y+ stays at 38% (35-40%). 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 62% and GPU 72%. At 1440p, that shifts to CPU 59% and GPU 80%, and at 4K it reaches CPU 53% and GPU 86%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
4K (Ultra HD) Medium is the most balanced preset based on this dataset. It runs around CPU 67% (61-73%) and GPU 88% (77-100%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Xeon Gold 6438Y+ remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Xeon Gold 6438Y+ 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 Gold 6438Y+ paired with the GeForce RTX 4090 can run Fortnite smoothly up to 1440p achieving around 64 FPS at Ultra quality. Your GPU is 136% above the recommended specs, and your CPU is 377% above the recommended requirements.
This CPU + GPU combo costs approximately $2038 ($389 CPU (Rank #346 Value) + $1649 GPU (Rank #77 Value)). Your Xeon Gold 6438Y+ 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 9355P is a great upgrade option for around $2998 (Rank #287 for value).
Your Xeon Gold 6438Y+ 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: 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 Xeon Gold 6438Y+ 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.
