Fortnite

The AMD Ryzen 5 8400F paired with the NVIDIA GeForce RTX 3080 delivers a robust Fortnite experience, with performance scaling predictably across resolutions and settings. The data indicates a system that is exceptionally strong at 1080p and 1440p, while 4K gaming demands more from the GPU, exposing its limits at higher graphical presets. This analysis breaks down the measured FPS data to understand where each component's role begins and ends.

Resolution Scaling

Resolution scaling in Fortnite for this combo shows a clear progression of GPU load. At 1920x1080 with Low settings, the average FPS is 324, which is extraordinarily high and indicates that the CPU is the primary driver at this level. Moving to 2560x1440 Low, the average drops to 206 FPS, a 36% reduction, showing the GPU beginning to take on more work. At 3840x2160 Low, the average is 109 FPS, a 47% drop from 1440p, solidifying that the RTX 3080 is now the bottleneck.

The scaling pattern changes with higher settings. At High settings, the transition from 1080p (177 FPS) to 1440p (112 FPS) is a 37% drop, and from 1440p to 4K (59 FPS) is a 47% drop. This shows that at 4K High, the GPU is heavily taxed, and the frame rate falls below the 60 FPS threshold for smooth play. The Ultra preset at 4K produces an average of 39 FPS, which is a 47% drop from the 74 FPS seen at 1440p Ultra. The data suggests that the limiting component shifts from the CPU at 1080p to the GPU at 4K, with the RTX 3080's performance ceiling being reached at the highest resolution. The difference between Low and Ultra at 4K is substantial—109 FPS versus 39 FPS—highlighting how much headroom the GPU has at lower settings and how quickly it saturates with increased visual fidelity.

CPU Role

The AMD Ryzen 5 8400F is a 6-core, 12-thread processor based on the Zen 4 architecture, with a base clock of 4.20 GHz and a boost clock of 4.70 GHz. Its benchmark scores are strong for a mainstream chip, with a Cinebench R23 multi-core score of 20851 and a single-core score of 2943. The processor's single-thread performance is particularly relevant for Fortnite, a game that often relies on a few heavily loaded threads. The 3DMark single-thread score of 951 and the Passmark single-thread score of 3685 indicate solid per-core performance.

In the measured FPS data, the CPU's role is most evident at 1080p Low, where the average of 324 FPS is high enough that the GPU is not the limiting factor. The 8400F's 12 threads and high boost clock allow it to feed the RTX 3080 efficiently at lower resolutions. However, the data also shows that the CPU is not the primary constraint at higher resolutions. For instance, at 4K Ultra, the average FPS is 39, which is far below what the CPU could theoretically support, confirming that the GPU is the bottleneck. The CPU's nearest rival, the AMD Ryzen 5 7500F, has an average score of 24964, with a deltaPct of 0.2, meaning the 8400F is essentially on par with it. This puts the 8400F in the 77th percentile of all CPUs, indicating it is a capable processor for gaming, but not an extreme high-end part. The data shows that at 1080p, the CPU is doing the heavy lifting, but as resolution increases, its influence wanes.

How This Combo Ranks

The AMD Ryzen 5 8400F and NVIDIA GeForce RTX 3080 combination holds a rank of 1043 out of 3700 tested combos in Fortnite. This places it in the top 28% of all tested systems, which is a strong showing for a mid-range CPU paired with a high-end GPU. The ranking reflects the balance of the system; the 8400F is not holding back the RTX 3080 significantly, allowing the combo to achieve high frame rates in most scenarios. The percentile ranking of the CPU is 77, and the GPU is 68, suggesting that the CPU is relatively stronger than the GPU when compared to their respective pools. This is corroborated by the FPS data, where the CPU is able to push high frame rates at 1080p, but the GPU's performance ceiling is hit at 4K. Compared to other combos, this pairing is well-optimized for competitive play at 1440p, where the average FPS on High settings is 112, and on Medium it is 145. The rank of 1043 indicates that while not a top-tier enthusiast setup, it outperforms a majority of the systems tested, making it a reliable choice for high-refresh-rate gaming.

Measured FPS Breakdown

The measured FPS data provides a detailed look at how the system performs across three resolutions and four settings presets. At 1920x1080, the system is extremely capable. With Low settings, the average FPS is 324, which is exceptionally high. Medium settings yield an average of 228 FPS, with a minimum of 194 and a maximum of 262. High settings produce 177 FPS on average, and even the demanding Ultra preset maintains an average of 117 FPS. At this resolution, the system is clearly CPU-bound at lower settings, as the frame rates are far above what the GPU would typically render.

Moving to 2560x1440, the performance remains impressive but starts to show the GPU's influence. Low settings average 206 FPS, Medium settings average 145 FPS with a minimum of 123 and maximum of 167, High settings average 112 FPS, and Ultra settings drop to 74 FPS. The scaling from Low to Ultra at this resolution is consistent, with each preset step reducing the average by roughly 30-40 FPS. At 3840x2160, the GPU becomes the primary constraint. Low settings still deliver a playable 109 FPS, but Medium settings drop to 77 FPS, with a minimum of 65 and maximum of 88. High settings average 59 FPS, which is marginal for smooth gameplay, and Ultra settings fall to 39 FPS, which is not ideal for a fast-paced game like Fortnite. The data shows that the system is best suited for 1080p and 1440p gaming, where it can deliver high frame rates across all settings. At 4K, the user must compromise on settings to maintain playable frame rates.

Settings Recommendations

Based on the measured FPS data, the optimal settings depend on the target resolution and desired frame rate. For players with a 1920x1080 monitor, the High preset provides an excellent balance, delivering an average of 177 FPS, which is well above the 144Hz refresh rate common on such displays. The Ultra preset, at 117 FPS, is also viable for those who prioritize visual fidelity, but the High preset offers a significant performance boost with minimal visual difference in a competitive game. For 2560x1440, the Medium preset is the best choice for high-refresh-rate gaming, as it averages 145 FPS, which is suitable for a 144Hz monitor. The High preset, at 112 FPS, is still smooth but may not fully utilize a 144Hz display. The Low preset, at 206 FPS, is overkill for most monitors but could be used for maximum competitive advantage. At 3840x2160, the Low preset is the only option that guarantees a high frame rate, averaging 109 FPS. The Medium preset, at 77 FPS, is playable but may not be ideal for fast-paced action. The High preset at 59 FPS and Ultra at 39 FPS are not recommended for a competitive shooter, as they fall below the 60 FPS threshold. For the best overall experience, the data suggests using Medium or High settings at 1440p, as this provides a strong balance of visual quality and performance.

GPU Role

The NVIDIA GeForce RTX 3080 is a high-end graphics card based on the Ampere architecture, with a GA102 chip and 8704 shading units. It features 10 GB of GDDR6X memory on a 320-bit bus, providing a memory bandwidth of 760.3 GB/s. The GPU's boost clock is 1710 MHz, and its FP32 performance is 29.77 TFLOPS. In Fortnite, the GPU's role is most apparent at higher resolutions and settings. The data shows that at 4K, the GPU's performance ceiling is reached, as evidenced by the significant FPS drops from Low to Ultra settings. The RTX 3080's 10 GB of VRAM is sufficient for Fortnite at 4K, but the raw compute power is the limiting factor. The GPU's benchmark scores, such as a Passmark G3D score of 25086 and a Geekbench OpenCL score of 152423, indicate strong performance, but its percentile ranking of 68 shows it is not at the very top of the GPU hierarchy. The nearest rivals, such as the NVIDIA P106-100 and AMD Radeon RX 6600M, have similar average scores, with deltaPct values of -0.3 and -0.4, respectively. This suggests that the RTX 3080 is a well-rounded card, but in Fortnite, it is the component that limits performance at 4K, while the CPU handles lower resolutions with ease. The GPU's 68 RT cores and 272 tensor cores are not heavily utilized in Fortnite, which is primarily a rasterization-based game, but the sheer number of shading units is what drives the high frame rates at 1440p.
