Fortnite

The AMD Ryzen 7 5700 and NVIDIA GeForce RTX 5090 pairing in Fortnite produces a wide performance envelope that depends heavily on how you balance resolution and graphical presets. The measured data shows this system is capable of extreme frame rates at lower resolutions, but you’ll need to make deliberate choices about settings to get a smooth 4K experience. This analysis breaks down the measured FPS results to help you pick the right configuration for your target display.

Settings Recommendations

The best experience depends entirely on your display’s resolution and refresh rate. The data shows a clear hierarchy of presets at each resolution, but the gap between them changes as you scale up. At 1080p, any preset delivers playable frame rates, but the differences between Low and Ultra are substantial. The Low preset hits 395 FPS average, Medium drops to 345 FPS, High falls to 267 FPS, and Ultra bottoms out at 176 FPS. If you have a 360Hz or higher refresh rate monitor, Low is the only preset that lets you approach the ceiling, while Medium still provides a massive frame rate advantage for competitive play.

At 1440p, the same pattern holds but with lower absolute numbers. Low averages 311 FPS, Medium 219 FPS, High 170 FPS, and Ultra 112 FPS. For a 240Hz 1440p display, Medium is the sweet spot because it keeps you above 200 FPS average while looking noticeably better than Low. High is viable for 165Hz panels, but Ultra will leave frame rate headroom unused.

At 4K, the situation changes completely. Ultra averages just 59 FPS, which is borderline for smooth gameplay on a 60Hz display but insufficient for high-refresh 4K panels. High averages 90 FPS, Medium 116 FPS, and Low 164 FPS. The Medium preset stands out as the best 4K choice because it’s the only one that clears 100 FPS average while still providing decent visual quality, and it has measured minimums of 98 FPS and maximums of 133 FPS. If you’re targeting 4K 120Hz, Medium is the only measured preset that gets you there consistently.

GPU Role

The RTX 5090’s memory configuration is a major factor in these results. The GPU carries 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. That bandwidth is what allows the card to maintain high frame rates at 4K, where the data shows it still produces 164 FPS on Low settings. The 32 GB capacity is far more than Fortnite needs, but it ensures there’s no memory pressure at any resolution or preset combination in this game.

Clock speeds also play a role. The GPU runs at a base clock of 2017 MHz and boosts to 2407 MHz. These clocks, combined with the 21760 shading units and 680 TMUs, explain why the card scales so aggressively when you lower settings. At 1080p Low, the GPU is clearly not the limiting factor — it’s pushing 395 FPS average, which suggests the CPU is holding it back. But at 4K Ultra, the GPU workload becomes so heavy that the frame rate drops to 59 FPS average, showing the card’s raw throughput is being saturated by the combination of high resolution and maximum settings.

The RTX 5090’s compute capabilities also matter for Fortnite’s rendering pipeline. With 170 RT cores and 680 tensor cores, the card has substantial headroom for ray tracing and DLSS features, though the measured data here does not include those specific modes. The FP32 throughput of 104.8 TFLOPS gives the card enough raw compute to handle the game’s physics and rendering at high settings without bottlenecking the CPU.

Resolution Scaling

The FPS drop from 1080p to 4K reveals a lot about where the bottleneck lies. At Low settings, the system goes from 395 FPS at 1080p to 311 FPS at 1440p to 164 FPS at 4K. That’s a 58% reduction from 1080p to 4K, which is substantial but not as severe as you might expect from a 4x pixel count increase. This suggests that at Low settings, the CPU is significantly limiting performance, especially at 1080p and 1440p. The Ryzen 7 5700’s 8 cores and 16 threads are enough to feed the GPU at lower resolutions, but they cap out around the 300-400 FPS range.

At Medium settings, the pattern is more GPU-bound. The system delivers 345 FPS at 1080p, 219 FPS at 1440p, and 116 FPS at 4K. The drop from 1440p to 4K is 47%, which aligns more closely with the GPU’s resolution scaling. At High settings, the numbers are 267 FPS at 1080p, 170 FPS at 1440p, and 90 FPS at 4K — again showing a consistent scaling pattern that points to the GPU as the primary limiter.

Ultra settings show the steepest scaling. The system produces 176 FPS at 1080p, 112 FPS at 1440p, and just 59 FPS at 4K. That’s a 66% drop from 1080p to 4K, which indicates the GPU is fully saturated at 4K Ultra. The 4K Ultra result of 59 FPS is barely half the 1080p Ultra result, and this steep drop is a clear sign that the RTX 5090’s pixel and texture throughput is the limiting factor at the highest settings.

FAQ

Q: What’s the best preset for competitive play at 1080p?

A: Low settings give you the highest average frame rate at 395 FPS, which is ideal for high-refresh competitive monitors. Medium is a good alternative at 345 FPS if you want better visuals without a massive frame rate penalty.

Q: Can this combo handle 4K gaming smoothly?

A: Yes, but you need to choose your preset carefully. Medium settings average 116 FPS at 4K with minimums of 98 FPS, making it the only preset that consistently clears 100 FPS. High averages 90 FPS, while Ultra drops to 59 FPS.

Q: Is the CPU or GPU the bottleneck at 1080p?

A: The data suggests the CPU becomes the limiter at lower resolutions. At 1080p Low, the system hits 395 FPS average, but the Ryzen 7 5700’s performance ceiling appears to cap frame rates in that range. The GPU has far more headroom than the CPU at 1080p.

Q: How does the RTX 5090’s memory affect Fortnite performance?

A: The 32 GB of GDDR7 memory on a 512-bit bus with 1.79 TB/s bandwidth ensures there’s no memory-related frame rate drops in Fortnite at any resolution or preset. The bandwidth is particularly important for maintaining high FPS at 4K.

Q: What frame rates can I expect at 1440p with High settings?

A: The measured average is 170 FPS, which is well above 144Hz refresh rates. If you want to push a 240Hz monitor, Medium settings at 219 FPS average is the better choice.

Q: Why does Ultra settings perform so much worse than High?

A: The gap is significant across all resolutions. At 4K, Ultra averages 59 FPS compared to High’s 90 FPS, a 34% drop. At 1080p, Ultra averages 176 FPS versus High’s 267 FPS. The Ultra preset imposes a heavy rendering load that the GPU struggles to sustain.

How This Combo Ranks

This specific CPU-GPU combination ranks 140th out of 3700 tested combos in Fortnite. That puts it in the top 3.8% of all configurations in the database. The ranking reflects the system’s ability to produce high frame rates at 1440p and 4K, but it’s not in the absolute top tier because the CPU holds back the RTX 5090 in some scenarios. The Ryzen 7 5700’s average benchmark score of 25517 places it in the 78th percentile of all CPUs, while the RTX 5090’s average score of 79842 places it in the 92nd percentile of all GPUs. This mismatch suggests the GPU is the stronger component in this pairing, and the CPU is likely the limiting factor at lower resolutions.

The combo’s rank of 140 out of 3700 is respectable, but it’s notably many higher-ranked combinations likely use faster CPUs. The data shows that at 1080p Low, the system hits 395 FPS, but a stronger CPU might push that number higher. The RTX 5090 is clearly capable of more, as evidenced by its 4K Low result of 164 FPS, which is still very high. If you’re building for maximum Fortnite performance, this combo ranks well, but you could improve the ranking by pairing the RTX 5090 with a faster CPU.

CPU Role

The Ryzen 7 5700’s specifications explain its role in these results. With 8 cores, 16 threads, a base clock of 3.70 GHz, and a boost clock of 4.60 GHz, this Zen 3 processor offers solid multi-threaded performance for a desktop CPU. Its 16 MB of L3 cache is moderate by modern standards, but it’s sufficient for Fortnite’s workload. The processor’s benchmark results show a single-thread score of 901 in 3DMark and 2916 in Cinebench R23, which are decent but not exceptional numbers.

The CPU’s impact is most visible at 1080p. At that resolution, the system produces 395 FPS on Low settings, but the frame rate drops to 345 FPS on Medium and 267 FPS on High. This scaling suggests the CPU is handling the game logic and draw calls well, but it’s not leaving a lot of headroom for higher settings. The 8-core configuration is well-suited for Fortnite, which can use multiple threads, but the CPU’s 65W TDP and 3.70 GHz base clock limit its sustained performance.

At 1440p and 4K, the CPU’s role diminishes as the GPU becomes the bottleneck. The frame rates at those resolutions scale more with GPU settings than with CPU capabilities. However, the CPU still needs to keep up with the RTX 5090’s high frame rates at 1440p Low, where the system averages 311 FPS. The Ryzen 7 5700’s 16 threads are enough to prevent a CPU bottleneck in most scenarios, but the data suggests that at 1080p, the CPU is the limiting factor. If you want to maximize frame rates at 1080p, a faster CPU would likely improve results, but for 1440p and 4K gaming, this processor is sufficient to feed the RTX 5090.
