1Can the EPYC 9124 and GeForce RTX 4090 run Fortnite well?
The EPYC 9124 and GeForce RTX 4090 will struggle to run Fortnite at smooth framerates.
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.
Performance Report
The GeForce RTX 4090 is 136% above the recommended GPU (GeForce GTX 1080) for Fortnite. The EPYC 9124 is 232% above the recommended CPU (Core i5-7300U).
No major FPS-ceiling mismatch detected. The GeForce RTX 4090 and EPYC 9124 stay close in effective frame-generation ceiling across the tested resolutions and quality settings.

The EPYC 9124 + GeForce RTX 4090 pairing runs this title with CPU utilization between 39% and 84% and GPU utilization between 35% and 100%. EPYC 9124 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 74% at 1080p to 86% at 4K, while CPU averages move from 65% to 60%.
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 EPYC 9124 stays at 49% (39-59%). 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 65% and GPU 74%. At 1440p, that shifts to CPU 63% and GPU 84%, and at 4K it reaches CPU 60% and GPU 86%. 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% (60-75%) and GPU 88% (77-100%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while EPYC 9124 remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the EPYC 9124 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.

The EPYC 9124 and GeForce RTX 4090 will struggle to run Fortnite at smooth framerates.
This CPU + GPU combo costs approximately $2732 ($1083 CPU (Rank #258 Value) + $1649 GPU (Rank #77 Value)). This is a well-balanced setup, meaning you're getting good value from both components without significant waste.
This setup is already well-balanced for Fortnite. No significant bottleneck - CPU and GPU are well matched across all settings. Both the EPYC 9124 and GeForce RTX 4090 complement each other effectively, so upgrading either component individually would yield diminishing returns. If you want more FPS, you'd benefit most from upgrading both CPU and GPU together.
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 9124 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.
