Roblox

The Intel Core i5-13400F paired with the Intel Arc B580 delivers a decisive performance envelope for Roblox, with measured frame rates that far exceed the 60 FPS playability threshold at every resolution and preset combination tested. The data shows a system that is not merely playable but overwhelmingly capable, with average frame rates ranging from a low of 73 FPS at 4K Ultra to a high of 297 FPS at 1080p Low. This combination ranks 2777 out of 3711 tested combos for this game, placing it in the upper portion of the database, and its performance is characterized by headroom that allows users to prioritize visual fidelity without sacrificing smoothness.

Measured FPS Breakdown

The measured FPS data reveals a clear scaling pattern across the three tested resolutions. At 1920x1080, the system operates at exceptionally high frame rates. The Low preset produces an average of 297 FPS, which is the highest average recorded across all tests. Moving to the Medium preset, the average drops to 270 FPS, with a minimum of 230 FPS and a maximum of 311 FPS. The High preset yields an average of 239 FPS. The most demanding setting at this resolution, Ultra, still maintains an average of 194 FPS. These figures indicate that at 1080p, the combination of the i5-13400F and Arc B580 is never strained, with even the Ultra preset retaining nearly triple the playable threshold.

At 2560x1440, the performance scales down proportionally but remains exceptionally high. The Low preset averages 198 FPS, while Medium averages 180 FPS with a minimum of 153 FPS and a maximum of 207 FPS. High settings produce an average of 160 FPS. The Ultra preset at 1440p delivers an average of 129 FPS, which is still more than double the 60 FPS threshold. The transition from 1080p to 1440p shows a performance reduction of roughly 33-35% across most presets, which is a typical cost for the additional pixel workload, yet the absolute numbers remain far beyond what the game requires for smooth gameplay.

At 3840x2160, the system continues to deliver playable performance at all settings, though the margins shrink compared to lower resolutions. The Low preset averages 112 FPS. Medium settings produce an average of 102 FPS, with a minimum of 87 FPS and a maximum of 117 FPS. The High preset averages 90 FPS. The Ultra preset, representing the maximum visual load, averages 73 FPS, which is still 13 FPS above the 60 FPS playable threshold. The scaling from 1440p to 4K shows an additional reduction of approximately 43% from the 1440p Ultra score, which aligns with the roughly 2.25x increase in pixel count, suggesting the GPU is the limiting factor at this resolution, though still within comfortable playable territory.

Across all resolutions, the Medium preset is the only one with complete min/max data available. The minimum frame rates at Medium settings are 230 FPS at 1080p, 153 FPS at 1440p, and 87 FPS at 4K. These minimums indicate that even in demanding scenes, the frame rate does not dip below playable levels, with the lowest recorded minimum of 87 FPS at 4K still exceeding the playable threshold by a substantial margin. The maximum frame rates at Medium settings reach 311 FPS at 1080p, 207 FPS at 1440p, and 117 FPS at 4K, demonstrating consistent frame delivery without severe spikes or drops.

Best Settings per Resolution

The best settings per resolution are determined by identifying the most demanding preset that maintains an average frame rate at or above 60 FPS. At every resolution tested, the Ultra preset qualifies as the best setting, which indicates the system has no need to compromise on visual quality.

At 1920x1080, the Ultra preset achieves an average of 194 FPS, making it the clear choice for maximum visual fidelity. This is not a borderline case; the frame rate is over three times the playable threshold, so there is no performance penalty for enabling the highest settings.

At 2560x1440, the Ultra preset averages 129 FPS. This is again far above the 60 FPS threshold, with a margin of 69 FPS. The reduction from the 1080p Ultra score of 194 FPS to 129 FPS represents a 33.5% decrease, but the absolute performance remains so high that Ultra is the unambiguous recommendation.

At 3840x2160, the Ultra preset averages 73 FPS, which is the lowest average recorded in the entire dataset but still above the playable threshold. The margin here is 13 FPS, which is narrower than at lower resolutions but still provides a buffer for fluctuating scenes. The data shows that Ultra at 4K is playable, though users who prefer a larger safety margin might consider High settings at 90 FPS, but the verdict based on the threshold is that Ultra remains the best setting that stays at or above 60 FPS.

Similar Performance Alternatives

The CPU and GPU each have nearest rivals that would produce similar benchmark performance, which translates to comparable behavior in Roblox. For the Intel Core i5-13400F, with an average benchmark score of 25292, the closest alternatives are the AMD Ryzen 9 6900HS with a score of 25284 (a delta of 0%), the Intel Core 5 120 with a score of 25362 (0.3% higher), the AMD Ryzen 5 5600X3D with a score of 25365 (0.3% higher), and the AMD Ryzen 7 6800H with a score of 25201 (0.4% lower). These CPUs are effectively equivalent in benchmark performance, meaning a system built with any of them paired with the Arc B580 would deliver nearly identical frame rates in Roblox, as the game is not particularly sensitive to the small differences between these processors.

For the Intel Arc B580, with an average benchmark score of 23021, the nearest GPU rivals are the AMD Radeon RX 580 2048SP with a score of 23061 (0.2% higher), the NVIDIA GeForce RTX 2080 with a score of 22895 (0.6% lower), the NVIDIA GeForce RTX 3080 with a score of 23172 (0.7% higher), and the NVIDIA P106-100 with a score of 23249 (1% higher). The deltas between these GPUs are all within one percentage point, indicating that in Roblox, which is a relatively light GPU load, these cards would perform within a few FPS of the Arc B580 at any given resolution and preset. Users with any of these GPUs paired with a comparable CPU should expect essentially identical gameplay experiences.

The practical implication is that the combination's performance in Roblox is not unique to the specific i5-13400F and Arc B580 pairing. Any of the four rival CPUs combined with any of the four rival GPUs would produce frame rates within a narrow band of the measured results, given the tight clustering of benchmark scores. The CPU rivals all sit within 0.4% of each other, and the GPU rivals all sit within 1% of each other, so the entire matrix of sixteen possible pairings would yield results indistinguishable from the measured configuration in actual gameplay.

How This Combo Ranks

The Intel Core i5-13400F and Intel Arc B580 combination holds a rank of 2777 out of 3711 tested combos for Roblox. This places the system in the 74.8th percentile of all tested combinations, meaning it outperforms roughly three-quarters of the configurations in the database for this specific game. While this is not a top-tier ranking, it reflects the fact that Roblox is not an exceptionally demanding game, and many high-end combinations achieve similar or higher frame rates.

The rank is somewhat surprising given the measured frame rates, which are extremely high across all resolutions. The explanation lies in the distribution of tested combos: many systems in the database are equipped with flagship CPUs and GPUs that produce even higher frame rates in a game like Roblox, where the ceiling is often limited by the game engine rather than the hardware. The i5-13400F at the 77th percentile of all CPUs and the Arc B580 at the 68th percentile of all GPUs are both solidly mid-to-upper-range components, and their combined rank reflects this positioning rather than any deficiency in actual gameplay.

The rank of 2777 out of 3711 means there are 934 tested combinations that perform better in Roblox, and 2776 that perform worse. Given that the measured frame rates are already far above the playable threshold at all settings, the practical difference between this rank and a higher rank is negligible for the user experience. A system ranked in the top 100 would produce higher FPS numbers, but at 194 FPS at 1080p Ultra, the additional performance would be imperceptible on most displays, which are typically capped at 144Hz or 165Hz.

The Verdict

This PC can run Roblox at every resolution and preset combination tested, with all configurations clearing the 60 FPS playable threshold. At 1920x1080, the system delivers between 194 FPS (Ultra) and 297 FPS (Low), with the Ultra preset providing the best visual experience at an average of 194 FPS. At 2560x1440, the range is 129 FPS (Ultra) to 198 FPS (Low), with Ultra averaging 129 FPS. At 3840x2160, the range narrows to 73 FPS (Ultra) to 112 FPS (Low), with Ultra still maintaining an average of 73 FPS.

The verdict by resolution is unambiguous: all tested settings are playable at all resolutions. The best settings per resolution are Ultra at every resolution, with average frame rates of 194 FPS at 1080p, 129 FPS at 1440p, and 73 FPS at 4K. The system has sufficient headroom that even the most demanding configuration, 4K Ultra, does not approach the playable threshold, leaving a 13 FPS buffer. For users with high-refresh-rate monitors, the 1080p and 1440p results are particularly strong, with Ultra presets exceeding 120 FPS, which is sufficient for 120Hz displays, and the Low presets exceeding 198 FPS, which can drive 165Hz or 240Hz displays.

The only caveat is at 4K Ultra, where the 73 FPS average is above the threshold but not by a massive margin. Users who experience particularly busy scenes with many players or complex user-generated content might see frame rates dip closer to the threshold, though the minimum recorded at 4K Medium is 87 FPS, suggesting the engine maintains stability. Overall, this is a system that requires no compromises for Roblox, regardless of display resolution or graphics settings.

CPU and GPU Roles

The division of labor between the Intel Core i5-13400F and the Intel Arc B580 varies by resolution, as evidenced by the scaling of frame rates across the tested configurations. At 1920x1080, the frame rates are exceptionally high, with the Low preset reaching 297 FPS. This suggests that at this resolution, the GPU is not the primary constraint, as the pixel workload is light enough that the CPU's ability to feed the graphics card becomes the more significant factor. The i5-13400F, with a boost clock of 4.60 GHz and 16 threads, is well-equipped for this role, and the high frame rates at 1080p indicate that the processor can maintain sufficient throughput to keep the GPU saturated.

At 2560x1440, the frame rates drop by approximately one-third across all presets, which corresponds to the 78% increase in pixel count from 1080p. This scaling suggests that the GPU begins to take on a more significant role at this resolution, as the additional pixel workload directly impacts the frame rate. However, the CPU is still capable of keeping pace, as evidenced by the 129 FPS average at Ultra, which is a demanding load for the GPU but still well within the CPU's capabilities.

At 3840x2160, the GPU becomes the clear limiting factor. The frame rate at Ultra drops to 73 FPS, which is a 43.4% reduction from the 1440p Ultra score of 129 FPS. This reduction is larger than the proportional increase in pixel count would suggest, indicating that the Arc B580 is nearing its limits at this resolution and the CPU's performance is no longer a bottleneck. The fact that the 4K Low preset achieves 112 FPS while 4K Ultra achieves 73 FPS shows that the GPU workload is the dominant factor at this resolution, with the CPU providing adequate support but the graphics card determining the final frame rate.

The scaling pattern across presets also reveals the GPU's role. At 1080p, the difference between Low (297 FPS) and Ultra (194 FPS) is 103 FPS, a 34.7% reduction. At 1440p, the difference between Low (198 FPS) and Ultra (129 FPS) is 69 FPS, a 34.8% reduction. At 4K, the difference between Low (112 FPS) and Ultra (73 FPS) is 39 FPS, a 34.8% reduction. This consistent ~35% reduction from Low to Ultra across all resolutions indicates that the GPU's performance scaling with settings is uniform, and the CPU's role remains constant, supporting the interpretation that the GPU is the primary determinant of performance at all resolutions, with the CPU providing a stable foundation that does not become a bottleneck even at the highest frame rates.
