Fortnite

The AMD Ryzen 7 5800XT paired with the NVIDIA GeForce RTX 3070 delivers a highly capable Fortnite experience, but the data reveals a distinct shift in system bottleneck behavior as resolution and settings change. At 1080p, the combination is heavily CPU-limited, producing very high frame rates that scale dramatically with lower settings. At 4K, the RTX 3070 becomes the primary constraint, with frame rates dropping to levels that highlight the GPU's workload limits. This analysis breaks down the measured performance, contextualizes the CPU's role, and provides a detailed ranking of this specific hardware combination against all other tested systems.

Resolution Scaling

The measured FPS data shows a clear and expected inverse relationship between resolution and performance, but the magnitude of the drop varies significantly by settings preset. At High settings, the average frame rate falls from 151.9 FPS at 1920x1080 to 94.6 FPS at 2560x1440, a reduction of approximately 37.7%. Moving further to 3840x2160, the average drops to 51 FPS, which is a 66.4% decrease from the 1080p result. This steep decline indicates that the GPU is facing a rapidly increasing workload as pixel count grows, with the RTX 3070's 8 GB of GDDR6 memory and 448.0 GB/s bandwidth being taxed heavily at higher resolutions.

The scaling pattern at Low settings tells a different story. At 1080p Low, the system produces a very high 278.3 FPS average. At 1440p Low, the average is 176 FPS, and at 4K Low, it is 95.2 FPS. While these are all excellent numbers, the percentage drop from 1080p to 4K is 65.8%, which is nearly identical to the High preset's drop. This suggests that even when graphical load is minimized, the GPU's raw throughput at 4K becomes the limiting factor. However, the absolute FPS at 1080p Low being so high indicates that the CPU is capable of feeding the GPU far more frames than it can render at lower resolutions.

The Ultra preset shows the most dramatic scaling. At 1080p, the average is 102.2 FPS, which drops to 62.8 FPS at 1440p and further to a demanding 33 FPS at 4K. The 4K Ultra result represents a 67.7% reduction from 1080p Ultra. This severe drop suggests that the combination of high pixel count and maximum graphical features overwhelms the RTX 3070's 20.31 TFLOPS of FP32 compute and its 46 RT cores. The data indicates that for 4K gaming with this GPU, players would need to use lower presets to maintain playable frame rates, while the CPU has ample headroom at that resolution.

CPU Role

The AMD Ryzen 7 5800XT is a Zen 3 architecture processor with 8 cores and 16 threads, operating on the AM4 socket. Its base clock of 3.80 GHz and boost clock of 4.80 GHz contribute to strong single-threaded performance, which is critical for Fortnite's game engine. The benchmark data supports this, with a Cinebench R23 single-core score of 3359 points and a 3DMark single-thread score of 959. These scores indicate that the CPU's per-core performance is robust, allowing it to drive high FPS in scenarios where the GPU is not the bottleneck.

In this game, the CPU's role is most evident at 1080p resolutions. The jump from 102.2 FPS at Ultra to 278.3 FPS at Low represents a 172.3% increase in performance, which is a far larger relative gain than what is seen at 4K (from 33 FPS to 95.2 FPS, a 188.5% increase, but from a much lower absolute base). The fact that 1080p Low achieves nearly triple the frame rate of 1080p Ultra strongly suggests that the CPU is capable of producing very high frame rates, and the GPU is the component that holds performance back when settings are increased. The Ryzen 7 5800XT's 32 MB of L3 cache and high boost clock help maintain consistent frame pacing in CPU-intensive scenes.

The CPU's multithreaded capabilities are also relevant. With a Cinebench R23 multicore score of 23794 points and a PassMark multithread score of 27988, the processor can handle background tasks and game logic without creating a bottleneck. However, the 3DMark 2-thread score of 1879 is notably lower relative to the 16-thread score of 7683, which implies that the game benefits from its ability to use multiple cores, but the single-thread performance is still the primary driver for high-FPS scenarios. The data shows that at 1080p, the system is CPU-bound at lower settings, while at 4K, the GPU's limitations dominate, regardless of the CPU's strong scores.

FAQ

Q: What is the highest average FPS this combo achieves in Fortnite?

A: The highest measured average FPS is 278.3 at 1920x1080 with Low settings.

Q: How does the combo perform at 4K Ultra settings?

A: At 3840x2160 with Ultra settings, the average FPS is 33, which is the lowest recorded result in the measured data.

How This Combo Ranks

In the database of tested hardware combinations for Fortnite, this specific pairing of the AMD Ryzen 7 5800XT and NVIDIA GeForce RTX 3070 holds a rank of 690 out of 1564 total combinations. This places it in the upper-middle tier of all tested systems, indicating that it is a solid performer but not at the absolute top end of the spectrum. The rank is determined by the measured FPS across all tested resolutions and settings, and this combo's strong 1080p performance is somewhat offset by its more modest 4K results.

The CPU's individual percentile of 86th versus all CPUs is higher than the GPU's 72nd percentile versus all GPUs, suggesting that the processor is a stronger component relative to its peers than the graphics card. This is reflected in the game's performance, where the GPU becomes the limiting factor at higher resolutions. The combo's rank of 690 out of 1564 suggests that many other systems, likely with more powerful GPUs, achieve higher average frame rates, particularly at 1440p and 4K. However, for 1080p gaming, this combination is likely to outperform a significant portion of the database, given the CPU's ability to push high frame rates.

The data shows that this combo's performance is well-balanced for high-refresh-rate 1080p gaming, but it falls behind in 4K scenarios where the RTX 3070's 8 GB memory capacity and compute power are insufficient to maintain high frame rates on demanding presets. The rank reflects this mixed profile, with the system being more competitive at lower resolutions.

Measured FPS Breakdown

The following table details the exact average FPS measurements for each resolution and settings preset:

| Resolution | Settings | Average FPS |

| :--------- | :------- | ----------: |

| 1920x1080 | Low | 278.3 |

| 1920x1080 | Medium | 196.2 |

| 1920x1080 | High | 151.9 |

| 1920x1080 | Ultra | 102.2 |

| 2560x1440 | Low | 176.0 |

| 2560x1440 | Medium | 126.1 |

| 2560x1440 | High | 94.6 |

| 2560x1440 | Ultra | 62.8 |

| 3840x2160 | Low | 95.2 |

| 3840x2160 | Medium | 66.0 |

| 3840x2160 | High | 51.0 |

| 3840x2160 | Ultra | 33.0 |

At 1920x1080, the system is capable of delivering an average of 278.3 FPS on Low settings, which drops to 102.2 FPS on Ultra. This represents a 63.3% reduction in performance when moving from the lowest to the highest preset. The Medium and High presets sit in between, with 196.2 and 151.9 FPS respectively, showing a consistent scaling pattern that is primarily influenced by the GPU's workload.

Moving to 2560x1440, the average FPS values are 176.0 for Low, 126.1 for Medium, 94.6 for High, and 62.8 for Ultra. The performance drop from Low to Ultra is 64.3%, which is similar to the 1080p trend. This consistency suggests that the GPU's rendering cost scales linearly with settings, while the CPU maintains a stable frame delivery rate.

At 3840x2160, the results are significantly lower. Low settings produce an average of 95.2 FPS, Medium yields 66.0 FPS, High drops to 51.0 FPS, and Ultra falls to 33.0 FPS. The gap between Low and Ultra is 65.3%, and the absolute numbers indicate that 4K gaming on Ultra is not a viable option for this combo, as the frame rate falls below the threshold for smooth gameplay. The 4K Low result of 95.2 FPS is still respectable but is lower than the 1080p Ultra result of 102.2 FPS, highlighting the heavy cost of the higher resolution.
