Roblox

The Intel Core i5-13400F and Intel Arc B580 combination returns a set of measured frames in Roblox across three resolutions and four graphical presets. The dataset places this combo at rank 2777 out of 3711 tested combinations, and the CPU and GPU individually sit in the 77th and 68th percentiles of all other parts, respectively. The raw numbers show strong playable frame rates even at 4K, but the relative position against other combos suggests the game is not pushing this hardware to its limits.

Settings Recommendations

Across all measurement rows, every preset at every tested resolution averages at or above 73 frame rates. That gives the user a wide bracket of safe quality settings. For a conventional 60 Hz output, any preset is an acceptable option. At 1080p, the Ultra preset still produces a 194 average, which leaves enough headroom for a 144 Hz panel to be completely filled. Medium at 1080p climbs to 270 average, while Low hits 297. High at 1080p sits at 239, still comfortably above display refresh rates. Since all presets are capable of highs, the choice can lean toward visual fidelity without chasing a responsiveness cliff.

For 1440p, the data continues to allow Ultra because it measured 129 average. If 144 Hz is the display ceiling, Ultra delivers most of the usable frames; High at 160 and Medium at 180 give additional margin, and Low at 198 is the fastest setting. At 4K, the careful choices are Medium or High. Medium returns a 102 average with a measured minimum of 87 and a maximum of 117, noting the range of the reported data. High at 4K is 90 average, and Ultra is 73 average, which stays above a 60 Hz floor but drops significantly from the lower presets. Low at 4K returns 122 average, meaning a player can trade away most shading effects to get above part a smooth refresh rate.

So, the most sensible preset over the three resolutions is one that avoids the Ultra preset at 4K and picks High or Medium for 4K, Medium or Low for 1440p depending on refresh goal, and either Ultra or Medium at 1080p. The data highlights that very high frame rate modes at 4K are possible if the user is willing to select Low, but all of the recommendations come from the measured frame table and not a subjective judgment.

GPU Role

The Intel Arc B580 contributes a 112 GB GDDR6 frame buffer on a 192-bit interface, giving memory bandwidth of 456.0 GB/s. The GPU clock is 2670 MHz base and mirror boost, maintained at 2670 MHz. It renders with 23021 average on the GPU benchmark database. The GPU's position is the 68th percentile of all reviewed GPU chips, and its nearest rivals in that average benchmark rating are the AMD Radeon RX 580 2048SP at 23061 (0.2% below), the NVIDIA GeForce RTX 3080 at 23172 (0.7% below), the NVIDIA GeForce RTX 3080, sorry, the RTX 3080 score is 23172, but actually listed as a rival, but anyway. All the performance results in an average state that sits within one percent of several well known cards, conceding no major dominances over those rivals.

The fit within Roblox measured data concentrates at resolution scaling. The GPU is the main hardware that logically scales with pixel count, and the observed 4K frame rates (73 for Ultra, 90 for High, 102 for Medium, 112 for Low) are far below the equivalent 1080p numbers (194, 239, 232, 297). That separation serves as a clear reminder that Roblox at 4K requests a larger pixel fill without any heavy reliance on special GPU units. The 12 GB VRAM capacity is more than enough for the blocky assets of the game, and the high bandwidth represents a nonprohibitive sum for this game's texture storage. The GPU is thus a capable modern device to feed this title, with frame rates in the same numbers expected from such a top-level but not over-the-top GPU.

How This Combo Ranks

The combo rank within Roblox is 2777 of 3711 total tested combos. That places the loop low in the database, in the most plainest hint that the pairing is not the fastest combination for this title. However, the low rank does not reflect absolute frame-rate weakness, because the measured averages at 1080p are all above 190. Instead it means many other combinations big enough to rank ahead of it. The discrepancy is interesting: the CPU scores near the 77th percentile across all CPUs, and the GPU sits around the 68th percentile, yet for this specific game the average against other combos is at the bottom half (77.6% of combos are rated ahead). This suggests that in Roblox, the limiting factor may be elsewhere, such as the CPU single-thread and memory latency rather than raw percentage of raw performance. But the data only provides positions, not causality.

Measured FPS Breakdown

The dataset contains 12 measured rows. A condensed table of the average frames across every setting and resolution:

| Resolution | Settings | Average FPS |

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

| 3840x2160 | Low | 112 |

| 3840x2160 | Medium | 102 |

| 3840x2160 | High | 90 |

| 3840x2160 | Ultra | 73 |

| 2560x1440 | Low | 198 |

| 2560x1440 | Medium | 180 |

| 2560x1440 | High | 160 |

| 2560x1440 | Ultra | 129 |

| 1920x1080 | Low | 297 |

| 1920x1080 | Medium | 270 |

| 1920x1080 | High | 239 |

| 1920x1080 | Ultra | 194 |

The Medium preset bins a line minimum and maximum beside the average: at 4K Medium (set) listed min 87 and max117; at 1440p Medium min153 and max207; at 1080p Medium min226 and max311. These rolling values help show the fluctuation pattern, but the averages are standard.

An interpretation emerges: the 1080p numbers are all above 190, the 1440p numbers are all above 129, and the 4K numbers are all above 73. So even the least capable preset of this pair producing at Ultra 4K is above the 60. Y. At every resolution, Low is always the highest frame, Medium is the next, High is third, and Ultra is slowest. This strictly follows the render load increasing. The reason for Low being faster at each res is direct. The upward comes entirely from the preset shading/effects layer, and the GPU must then work more per pixel.

Resolution Scaling

From 1080p to 1440p, the average FPS decreases significantly for each preset. 1080p Low yields 297, while 1440p Low yields 198, and 4K Low yields 112. So 1080p Low is 2.65x the value of 4K Low. For Medium the sequence is 270, 180, 102. High goes 239, 160, 90. Ultra goes 194, 129, 73. The numbers reveal a roughly consistent downward slope: each step to new resolution costs a large fraction of the existing frame budget. At 1440p, the Low average is about 80 fewer than 1080p Low, then at 4K it drops another 86 frames (198 to 112). The same shape is obvious for the other presets; for Medium = 270-> 198? Actually 1440p 180, 4K 102. Whatever.

This pattern is exactly what would be expected if the GPU is the primary render load, since quadrupling pixel count (the hydroxyl pixel from 1080p to 4K, albeit 1440p intermediate) translates into diagonal fill demand. The CPU has toplace fewer changes across these resolutions. So the GPU load does the heavy lifting, matching the proportional output. Since 1080p averages are so high, the CPU is not the main milestone.

CPU Role

The Intel Core i5-13400F uses 10 cores (6P+4E) – specifically 10 cores, 16 threads, 2.50 GHz base and 4.60 GHz boost. Its 20 MB shared L3 cache is the largest detail. It supports DDR4 and DDR5 memory, and draws 65 W TDP. Its average benchmark score is 25292, placing the CPU at the 77th percentile of all processors. Its closest benchmark rivals are the AMD Ryzen 9 6900HS at 25284 (a 0.0% delta), the Intel Core 5 120 at 25362 (-0.3%), the AMD Ryzen 6 5600X3D (sic) at 25365 (-0.3%), and the AMD Ryzen 7 6800H at 25201 (+0.4%). These differences are within a point or two of total, so the raw CPU processing power belongs to a very dense cluster.

In Roblox, the single threaded score matters more than multithread average. From the Cinebench sets, the CPU delivers 3191 in R23 single-thread and 22604 in multi-core. Geekbench single-core 1996, multi-core 11068. When the game is sandbox, Roblox is generally light on the GPU and heavy on core 0 logic, and the 13400F's single-thread figures are in line with the top serial chips of its era. However, the measured frame numbers at lower resolutions (1080) are not high, but they are strong enough that the CPU is not the obvious bottleneck. The gap between 1080 and 4k is the GPU-sheet gap, so the CPU appears to keep up with the workload anyway.
