Fortnite FPS on Atom Z3740 + GeForce RTX 5090

Fortnite FPS Performance Results

Fortnite

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.

📈Analysis

Which Component Limits FPS Most?

This chart answers a simple question: which upgrade is more likely to increase FPS first? In this case, the answer is clearly the CPU.

The largest gap appears at 1080p Low, where the Atom Z3740 reaches about 84 FPS, while the GeForce RTX 5090 still has headroom up to roughly 802 FPS.

That means the Atom Z3740 is hitting its performance ceiling first, leaving a 90% gap versus the GeForce RTX 5090's available headroom in the most unbalanced scenario. Across all tested settings, this pairing is CPU-limited in 12 out of 12 cases, with 0 GPU-limited and 0 balanced results.

Overall, this is a clearly CPU-bound combination in this game.

Verdict

Upgrade Recommendations

CPU-Limited

The Atom Z3740 is consistently the limiting part in this game, so upgrading the CPU is more likely to deliver a larger FPS gain than upgrading the GPU.

Detailed BreakdownShows which upgrade is more likely to unlock more FPS in each tested setting

This chart shows which upgrade is more likely to unlock more FPS in each tested setting. The lower line represents the part that reaches its limit first. When the CPU and GPU lines stay close together, the system is more balanced. When the gap widens, one component is more clearly holding the other back. Hover any setting to inspect it.

The lower line is the current limiter. The closer the two lines are, the more balanced the CPU and GPU are for this game.

🧠Methodology

Each line represents an estimated FPS ceiling for one component, rather than live usage alone.

To estimate the CPU ceiling, we pair the Atom Z3740 with GeForce RTX 5090, our current GPU anchor. To estimate the GPU ceiling, we pair the GeForce RTX 5090 with Ryzen 9 9950X3D, our current CPU anchor.

The lower line indicates the current limiter, since that component reaches its FPS ceiling first. In most scenarios, that is also the part most likely to deliver the bigger performance uplift if upgraded first.

The percentage shown represents the gap between the two ceilings. In practical terms, it shows how much of the stronger component's potential is left unused because the weaker one becomes the bottleneck first.

Fortnite FAQ

1Can the Atom Z3740 and GeForce RTX 5090 run Fortnite well?

Yes, the Atom Z3740 paired with the GeForce RTX 5090 can run Fortnite smoothly up to 1080p achieving around 83 FPS at Ultra quality. Your GPU is 140% above the recommended specs, and your CPU is 74% below the recommended requirements.

2Is there a more cost-effective setup to run Fortnite?

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.

3Which component should I upgrade first to improve Fortnite performance?

For Fortnite, upgrading the CPU would usually improve performance first. In the Performance Limiter Analysis, the Atom Z3740 is the side that most often caps the frame rate, while the GeForce RTX 5090 still has additional headroom in the tested presets. The main bottleneck appears on the CPU side. The largest gap shows up at 1080p Low, where the CPU reaches about 84 FPS while the GPU still has headroom up to roughly 802 FPS. Across all tested settings, the distribution is 0/12 GPU-limited, 12/12 CPU-limited, and 0/12 balanced.

4Does this setup support Frame Generation for Fortnite?

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.

5What are the minimum and recommended specs for Fortnite?

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 hardware falls below the minimum requirements for this game, which may result in poor performance.

6How accurate are these Fortnite FPS estimates for the Atom Z3740 and GeForce RTX 5090?

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.
