Roblox

The Intel Core i5-12400F paired with the NVIDIA GeForce RTX 5080 delivers exceptional performance in Roblox, with the data showing average frame rates that are multiples of the 60 FPS playability threshold across every tested resolution and preset. This combination ranks 207th out of 3711 tested combos in the database, placing it in the top tier of systems for this sandbox title, and the measured results indicate that this pairing is far more capable than Roblox demands at any setting.

Measured FPS Breakdown

The measured FPS data covers three resolutions and four quality presets, providing a complete picture of performance scaling. At 1920x1080, the lowest resolution tested, the RTX 5080 and i5-12400F produce staggering numbers. The Low preset averages 681.1 FPS, which drops to 620.5 FPS at Medium, 549 FPS at High, and 441.7 FPS at Ultra. The gap between Low and Ultra at 1080p is 239.4 FPS, representing a 35.1% reduction in average frame rate when moving from the least demanding to the most demanding preset. Even at Ultra, the system maintains an average well above any high-refresh-rate monitor's capabilities.

Moving to 2560x1440, the performance remains extremely high but shows the expected scaling from the resolution increase. The Low preset averages 454.4 FPS, Medium reaches 413.1 FPS, High produces 367.6 FPS, and Ultra still manages 297.6 FPS. The delta between Low and Ultra at this resolution is 156.8 FPS, a 34.5% drop. Compared to 1080p, the 1440p results are lower across all presets: Low is 33.3% lower, Medium is 33.4% lower, High is 33.1% lower, and Ultra is 32.6% lower. This consistent reduction of roughly one-third indicates that the resolution increase scales predictably with pixel count.

At 3840x2160, or 4K, the system continues to deliver frame rates that would be considered excessive for most games. The Low preset averages 257.1 FPS, Medium achieves 233.8 FPS, High produces 205.9 FPS, and Ultra drops to 165.9 FPS. The difference between Low and Ultra at 4K is 91.2 FPS, a 35.5% reduction, which mirrors the scaling seen at lower resolutions. When compared to 1440p, the 4K results are lower by 43.4% at Low, 43.4% at Medium, 44.0% at High, and 44.3% at Ultra. This larger drop from 1440p to 4K, compared to the 33% drop from 1080p to 1440p, reflects the higher pixel count requiring proportionally more GPU work.

CPU and GPU Roles

The data reveals that this game at these settings is overwhelmingly GPU-bound, but the CPU still plays a meaningful role at lower resolutions. The scaling from 1080p to 1440p shows a consistent one-third reduction in frame rates across all presets, which is exactly what would be expected if the GPU is the limiting factor and the resolution increase demands more pixel-fill work. The same pattern holds from 1440p to 4K, though the reduction is larger at 43-44%, suggesting that the GPU's memory bandwidth and compute resources become even more dominant at higher pixel counts.

The preset scaling within each resolution provides further insight. At 1080p, moving from Low to Ultra reduces the average FPS by 35.1%, while at 4K the reduction is 35.5%. This nearly identical percentage drop across resolutions indicates that the preset changes affect the GPU workload similarly regardless of resolution, and the CPU is not introducing a bottleneck at any point. The i5-12400F, with its 6 cores and 12 threads, shows no signs of limiting performance even at 1080p Low where the GPU is producing 681.1 FPS, a rate that would expose CPU limitations in many other titles.

The RTX 5080's role becomes more pronounced at 4K, where the Ultra preset produces 165.9 FPS compared to 441.7 FPS at 1080p Ultra. That 62.4% reduction from 1080p to 4K at Ultra is the largest single drop in the dataset, confirming that the GPU is the primary driver of performance differences. Conversely, the CPU's influence appears minimal, as the i5-12400F's single-thread score of 909 in 3DMark and multi-thread score of 5912 in 3DMark max threads provide ample headroom for a game like Roblox that does not typically stress high-core-count processors.

The Verdict

The data is unambiguous: this PC can run Roblox with exceptional headroom at every resolution and preset tested. The verdict by resolution lists all four settings—Low, Medium, High, and Ultra—as playable at 1920x1080, 2560x1440, and 3840x2160. The lowest average frame rate in the entire dataset is 165.9 FPS at 4K Ultra, which is 2.8 times the 60 FPS playable threshold. At 1440p, the worst case is 297.6 FPS at Ultra, and at 1080p it is 441.7 FPS at Ultra. Even the most demanding configuration tested, 4K Ultra, would deliver smooth gameplay on any display, including high-refresh-rate monitors. There is no scenario in the measured data where this combination approaches the 60 FPS threshold, and the margin is so large that users could enable additional graphical enhancements or run background tasks without concern.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which produces an average of 441.7 FPS. This is the maximum quality option and still delivers more than seven times the playability threshold.

At 2560x1440, the recommended setting is also Ultra, with an average of 297.6 FPS. This provides maximal visual quality while maintaining nearly five times the required frame rate.

At 3840x2160, Ultra remains the best choice, averaging 165.9 FPS. This is 2.8 times the 60 FPS threshold, meaning users can run the highest preset at 4K without any playability concerns. Since all presets clear 60 FPS at all resolutions, the best settings are simply the highest quality options available.
