Q: What is the lowest average FPS across all tested settings?

A: The lowest average is 170.4 FPS at 3840x2160 with Ultra settings.

Q: Is the CPU or GPU more likely to limit performance at 1080p?

A: At 1080p Low, the combo reaches 681 FPS, which is extremely high. The CPU's single-thread score of 868 in 3DMark and 2,029 in Cinebench R23 suggests it can drive high frame rates, but the GPU's massive compute power (56.28 TFLOPS) means neither component is a bottleneck at this resolution.

How This Combo Ranks

The combo's rank of 83 out of 1,800 places it in the 95.4th percentile of tested systems for Roblox. This is a top-tier result, driven primarily by the RTX 5080's raw performance. The GPU's average benchmark score of 59,188 puts it at the 89th percentile among all GPUs, and its nearest rivals—Intel Arc A570M (58,239), Intel Arc Pro A60 (60,326), Intel Arc A580 (57,756), and AMD Radeon Pro W5500X (57,661)—are all within a 2.6% delta. The CPU, while less dominant, still holds the 75th percentile with an average score of 17,181, and its nearest rivals are all within 0.2% of its score. In Roblox, the combination of a high-end GPU and a capable mid-range CPU yields frame rates that are far above typical display refresh rates, making this one of the fastest combos in the database.

Resolution Scaling

The measured FPS data shows a clear pattern: as resolution increases, average FPS drops, but the drop is more pronounced at higher settings. At 1080p Low, the combo averages 681 FPS; at 1440p Low, it drops to 454.3 FPS; and at 4K Low, it falls to 255.9 FPS. The same trend holds for Ultra: 445.6 FPS at 1080p, 297 FPS at 1440p, and 170.4 FPS at 4K. The absolute difference between 1080p and 4K is larger at Low settings (681 vs. 255.9, a gap of 425.1 FPS) than at Ultra (445.6 vs. 170.4, a gap of 275.2 FPS). This indicates that the GPU becomes the limiting factor as resolution climbs, because the pixel workload increases while the CPU's contribution remains constant. At 1080p, the CPU is capable of feeding the GPU enough data to reach very high frame rates, but at 4K, the GPU's rendering load dominates, pulling averages down. The fact that even 4K Ultra stays above 170 FPS shows that the RTX 5080 has ample headroom for this game, and the CPU is not a bottleneck at any tested resolution.

Measured FPS Breakdown

The following table lists all measured average FPS values from the FACT PACK:

| Resolution | Settings | Avg FPS |

|------------|----------|---------|

| 3840x2160 | High | 204.5 |

| 3840x2160 | Low | 255.9 |

| 3840x2160 | Medium | 236.7 |

| 3840x2160 | Ultra | 170.4 |

| 2560x1440 | High | 366.9 |

| 2560x1440 | Low | 454.3 |

| 2560x1440 | Medium | 414.4 |

| 2560x1440 | Ultra | 297 |

| 1920x1080 | High | 545.4 |

| 1920x1080 | Low | 681 |

| 1920x1080 | Medium | 620.3 |

| 1920x1080 | Ultra | 445.6 |

At every resolution, the ordering is consistent: Low > Medium > High > Ultra. The spread between Low and Ultra narrows as resolution increases—at 1080p the gap is 235.4 FPS, at 1440p it is 157.3 FPS, and at 4K it is 85.5 FPS. This suggests that the GPU's performance scaling with settings is more pronounced at lower resolutions, where the CPU can keep up with the GPU's output. At 4K, the GPU is already near its limit, so reducing settings yields smaller absolute gains. All values are well above 60 FPS, meaning the combo is playable at maximum settings even at 4K.

GPU Role

The RTX 5080 is the dominant component in this pairing. It features 16 GB of GDDR7 memory on a 256-bit bus, delivering 960.0 GB/s of bandwidth. Its base clock is 2295 MHz, boosting to 2617 MHz, with memory running at 1875 MHz (30 Gbps effective). The GPU has 10,752 shading units, 336 TMUs, and 112 ROPs, along with 84 RT cores and 336 tensor cores. Its FP32 compute is 56.28 TFLOPS, and it supports DirectX 12 Ultimate, OpenGL 4.6, and Vulkan 1.4. In Roblox, the GPU's high memory bandwidth and compute power are more than sufficient; even at 4K Ultra, the average FPS is 170.4, which is far above the 60 FPS threshold. The GPU's percentile rank of 89 and its average benchmark score of 59,188 place it among the top GPUs, and its nearest rivals are all within a 2.6% delta, confirming its high-end status. The 16 GB VRAM is unlikely to be a limiting factor in Roblox, as the game's asset sizes are modest, but the bandwidth ensures smooth texture streaming at high resolutions.

Settings Recommendations

Based on the measured FPS, the Ultra preset is recommended at all tested resolutions. At 1080p Ultra, the combo averages 445.6 FPS; at 1440p Ultra, 297 FPS; and at 4K Ultra, 170.4 FPS. All of these are well above the 60 FPS target, and even the lowest value (170.4) provides a smooth experience on high-refresh-rate displays. The data shows that the GPU has enough headroom to handle the highest settings without dropping below playable levels. For users with 4K displays, Ultra is still viable, as the 170.4 FPS average leaves a comfortable margin. If a user prioritizes maximum frame rates over visual fidelity, Low settings at 1080p yield 681 FPS, but the visual difference between Low and Ultra is substantial, and the performance gain is not necessary for most displays. Therefore, the Ultra preset offers the best balance of visual quality and performance across all resolutions.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor based on Rocket Lake, with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. It has 12 MB of shared L3 cache and supports DDR4 memory with a dual-channel bus and 51.2 GB/s bandwidth. Its launch MSRP was $157. In synthetic benchmarks, the CPU scores 868 in 3DMark single-thread, 2,029 in Cinebench R23 single-core, and 14,372 in Cinebench R23 multi-core. Its average benchmark score is 17,181, placing it at the 75th percentile among all CPUs. Its nearest rivals—AMD Ryzen 7 5700U, Intel Core i7-1260P, Intel Core Ultra 7 164U, and Intel Core i5-1240U—are all within 0.2% of its score, indicating that the i5-11400F is a solid mid-range performer. In Roblox, the CPU's single-thread performance is likely the more relevant factor, as the game is not heavily multi-threaded. The high FPS at 1080p (681 FPS on Low) demonstrates that the CPU can feed the GPU effectively at lower resolutions. At 4K, the CPU's role diminishes, as the GPU becomes the bottleneck. The 6 cores and 12 threads are more than adequate for Roblox, and the CPU's boost clock of 4.40 GHz ensures responsive gameplay. Overall, the i5-11400F provides sufficient processing power to complement the RTX 5080 without becoming a limiting factor in this title.
