Fortnite

The AMD Ryzen 5 7400F paired with the NVIDIA GeForce RTX 5090 presents a fascinating case study in Fortnite, where the data reveals a system that is overwhelmingly GPU-bound at higher resolutions but increasingly CPU-limited as resolution drops. The measured FPS across the board is exceptionally high, yet the scaling patterns from 1080p to 4K tell a clear story about which component is the primary driver of performance in this specific title.

Resolution Scaling

The FPS deltas between resolutions are sharp and highly revealing. At 1080p with Low settings, the combo produces 441 FPS average. Moving to 1440p Low drops that to 311 FPS, a 29.5% reduction, and then to 4K Low, it falls further to 164 FPS, which is 62.8% lower than the 1080p result. This dramatic decline as pixel count increases is the classic signature of a GPU that is being pushed to its limits; the RTX 5090’s raw compute is the bottleneck, not the CPU.

This pattern intensifies with higher settings. At Ultra settings, the 1080p average is 176 FPS, which drops to 112 FPS at 1440p (a 36.4% decrease) and then plummets to 59 FPS at 4K (a 66.5% decrease from 1080p). The 4K Ultra result of 59 FPS is particularly telling—it suggests that even this flagship GPU, with its massive 32 GB of GDDR7 memory and 1.79 TB/s bandwidth, is overwhelmed by the combination of maximum resolution and maximum detail in Fortnite. The data implies that while the card can brute-force 4K at lower presets, it cannot maintain high refresh rates at Ultra.

The scaling between Medium and High settings is also informative. At 4K, the jump from Medium (116 FPS) to High (90 FPS) is a 22.4% performance hit, while the jump from High to Ultra (59 FPS) is a staggering 34.4% hit. This non-linear degradation suggests that the Ultra preset introduces effects that are disproportionately expensive on the GPU, likely related to advanced rendering features that tax the 104.8 TFLOPS FP32 compute capability heavily. The data indicates that the limiting component at 4K is unambiguously the GPU, as the CPU’s role diminishes with each resolution increase.

CPU Role

The Ryzen 5 7400F is a 6-core, 12-thread processor based on Zen 4 architecture with a base clock of 3.70 GHz and a boost clock of 4.70 GHz. In Fortnite, a game that is typically not heavily multithreaded, this configuration appears to be more than sufficient to feed the RTX 5090 at lower resolutions. The 1080p Low result of 441 FPS is a strong indicator that the CPU can handle high frame generation, but the fact that it doesn’t scale even higher suggests a ceiling is being approached.

The CPU’s benchmark scores provide context for its gaming performance. Its Cinebench R23 multi-core score of 21,765 and single-core score of 3,072 are solid, placing it in the 83rd percentile of all CPUs. However, in the context of Fortnite, the single-core performance is more critical, and the data shows that at 1080p, the system is likely hitting a CPU limitation. The gap between 1080p Low (441 FPS) and 1440p Low (311 FPS) is 130 FPS, which is a larger absolute drop than the 147 FPS drop from 1440p to 4K (311 to 164). This indicates that the CPU is still a significant factor at 1080p, but its influence wanes as the GPU takes over.

The 6-core, 12-thread configuration, with 32 MB of shared L3 cache, provides adequate headroom for Fortnite’s engine, which typically scales well with clock speed. The boost clock of 4.70 GHz is likely the key driver here, as the data shows the system can push past 400 FPS at 1080p Low, a feat that requires strong per-core performance. The CPU’s 65W TDP and 5nm process node also suggest efficient operation, but the benchmark results indicate that in this pairing, the CPU is rarely the primary bottleneck except at the very lowest resolution and settings.

How This Combo Ranks

The combo’s rank of 79 out of 2,740 tested configurations places it in the top 2.9% of all systems tested for Fortnite. This is a strong result, but it is notably not higher given the presence of the RTX 5090, which is the flagship GPU in the database. The data suggests that the Ryzen 5 7400F is holding the system back from even higher rankings, particularly at 1080p where the CPU’s limits are more apparent.

The GPU’s percentile rank of 92 versus the CPU’s percentile rank of 83 highlights this imbalance. While the RTX 5090 is in the 92nd percentile of all GPUs, the 7400F is only in the 83rd percentile of CPUs. This discrepancy suggests that in a game like Fortnite, which can be CPU-bound at high frame rates, the processor is the weaker link. The rank of 79, while impressive, might have been higher with a more powerful CPU, but the data shows that for most resolutions and settings, the combo still delivers exceptional performance.

The nearest CPU rivals in the database include the Intel Core i5-14600T and the AMD Ryzen 7 PRO 6850H, with scores within 0.3% of the 7400F. This indicates that the CPU is performing as expected for its class, but it is not an outlier in terms of compute power. The combo’s rank is likely buoyed by the GPU’s immense strength, which compensates for the CPU’s modest standing.

GPU Role

The NVIDIA GeForce RTX 5090 is a behemoth, with 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. Its 21,760 shading units and 680 TMUs provide immense pixel-pushing power, as evidenced by its 423.6 GPixel/s pixel rate. In Fortnite, this translates to high FPS even at demanding settings, but the data shows that the GPU is the primary bottleneck at 4K and at higher presets.

The GPU’s benchmark scores are equally impressive, with a PassMark G3D score of 39,650 and a Geekbench OpenCL score of 334,370. Its 3DMark Steel Nomad DX12 score of 18,355 further underscores its DirectX 12 prowess, which is relevant for Fortnite’s modern rendering pipeline. The GPU’s 92nd percentile rank reflects its dominance, but the measured FPS data shows that even this card has limits.

At 4K Ultra, the 59 FPS average is a clear sign that the GPU is maxed out, likely due to the combination of high resolution and the most demanding visual effects. The drop from High (90 FPS) to Ultra (59 FPS) is a 34.4% decrease, which is a significant hit for a single preset change. This suggests that the Ultra preset includes features like ray tracing or advanced shadows that are particularly taxing on the GPU’s 104.8 TFLOPS FP32 compute. The 575W TDP and 950W suggested PSU indicate the card is power-hungry, but the performance data justifies its presence in this high-end combo.

Measured FPS Breakdown

The measured FPS data provides a comprehensive view of the combo’s performance across twelve different configurations. At 1920x1080, the results are as follows: Low settings produce an average of 441 FPS, Medium produces 345 FPS with a range of 293 to 396, High produces 267 FPS, and Ultra produces 176 FPS. The progression shows a clear trend: each preset step up costs a significant chunk of performance, with the largest drop being from High to Ultra (91 FPS, or 34.1%).

At 2560x1440, the averages are 311 FPS for Low, 219 FPS for Medium (with a range of 186 to 252), 170 FPS for High, and 112 FPS for Ultra. The scaling from 1080p to 1440p at the same settings shows consistent drops: Low drops by 130 FPS (29.5%), Medium by 126 FPS (36.5%), High by 97 FPS (36.3%), and Ultra by 64 FPS (36.4%). This consistency indicates that the GPU is the limiting factor here, as the percentage drops are similar across settings.

At 3840x2160, the averages are 164 FPS for Low, 116 FPS for Medium (with a range of 98 to 133), 90 FPS for High, and 59 FPS for Ultra. The drop from 1440p to 4K is more severe: Low drops by 147 FPS (47.3%), Medium by 103 FPS (47.0%), High by 80 FPS (47.1%), and Ultra by 53 FPS (47.3%). This uniform percentage drop across all settings at the 4K resolution further confirms that the GPU is the sole bottleneck, as the CPU’s influence has faded entirely.

Settings Recommendations

Based on the measured FPS data, the optimal settings for this combo depend heavily on the target resolution and refresh rate. For 1080p users with a high-refresh monitor, the High preset at 267 FPS average is a strong choice, offering a balance of visual quality and performance. The Medium preset at 345 FPS is also viable for those with 360Hz panels, but the High preset provides a better visual experience without sacrificing too much speed. The Low preset at 441 FPS is only recommended for competitive play where maximum frame rate is paramount, as the visual downgrade is substantial.

For 1440p, the High preset at 170 FPS is the sweet spot, providing excellent visual fidelity while still exceeding the refresh rate of most 1440p monitors. The Medium preset at 219 FPS is a better option for 240Hz panels, but the data suggests that the visual uplift from Medium to High is worth the performance cost for most users. The Ultra preset at 112 FPS is playable but may not be ideal for fast-paced competitive matches where higher frame rates are preferred.

At 4K, the situation is more nuanced. The High preset at 90 FPS is the best choice for a smooth experience, as it stays above the 60 FPS threshold and offers good visual quality. The Medium preset at 116 FPS is even better for 120Hz displays, providing a significant performance boost over High with a modest visual penalty. The Ultra preset at 59 FPS is not recommended for competitive play, as it hovers near the 60 FPS mark and may cause inconsistent frame pacing. The Low preset at 164 FPS is surprisingly effective at 4K, offering a high frame rate experience that sacrifices visual detail but remains highly responsive. For the best overall experience, the Medium preset at 4K appears to be the most balanced, delivering 116 FPS average with a minimum of 98 FPS, ensuring smooth gameplay without hitting the low frame rates seen at Ultra.
