Roblox

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 3080 ranks 1059th out of 3711 tested combos for Roblox, placing it in the 72nd percentile of all configurations. This is a strong showing that puts the combo in the upper third of results, though not at the very top. The ranking reflects a system that is heavily overqualified for this specific title, where the measured frame rates are exceptionally high across every preset and resolution, indicating that the hardware is rarely the limiting factor. This position among the tested combos suggests that while the pairing is powerful, Roblox's engine and typical scene complexity do not fully utilize the available resources, leaving headroom that results in the high but not record-breaking rank.

GPU Role

The NVIDIA GeForce RTX 3080 is the dominant component in this pairing, and its specifications explain why the measured frame rates are so high. The GPU features 10 GB of GDDR6X memory on a 320-bit bus, delivering a bandwidth of 760.3 GB/s. This memory configuration is far beyond what Roblox typically requires, ensuring that texture streaming and asset loading at high resolutions are never bottlenecks. The boost clock of 1710 MHz and base clock of 1440 MHz, combined with 8704 shading units, provide immense raw compute throughput. The data shows the RTX 3080 sits at the 68th percentile among all GPUs, with its average benchmark score of 23172 placing it near rivals like the NVIDIA P106-100 and AMD Radeon Pro Vega 16, which are within 0.3% to 0.4% in average score. However, in Roblox specifically, the GPU's capabilities translate into average FPS figures that are dramatically higher than typical competitive titles, with the lowest measured average being 119 FPS at 4K Ultra. The GPU's 68 RT cores and 272 tensor cores are largely unused in this sandbox title, but the sheer rasterization power from its 29.77 TFLOPS FP32 performance is what drives the results. Given that the GPU percentile is 68 and the combo rank is in the 72nd percentile of all combos, the RTX 3080 is clearly performing at or above its expected level in this game, with the CPU not holding it back in the higher resolution presets.

Settings Recommendations

The measured data provides a clear hierarchy of performance across the four available presets, and the optimal choice depends on the user's display resolution. At 1080p, the average frame rates are so high that even the Ultra preset delivers 314 FPS, which is far beyond any display's refresh rate and represents the best visual quality without any practical performance penalty. The Medium preset at 1080p hits 438 FPS, but the jump to Ultra only costs 124 FPS while providing the full visual experience, making Ultra the clear choice for 1080p users. At 1440p, the pattern holds: Ultra delivers 210 FPS, which is still exceptionally smooth, while High drops to 259 FPS and Medium to 293 FPS. The data suggests that 1440p Ultra is the sweet spot for this combo, as the 210 FPS average is well above the 144Hz refresh rate that most high-end monitors use. At 4K, the situation changes: Ultra drops to 119 FPS, which is still playable but no longer in the "high refresh" territory. For 4K users, the High preset at 146 FPS offers a better balance, providing a 27 FPS improvement over Ultra with only a modest reduction in visual fidelity. The Medium preset at 4K yields 165 FPS, but the 19 FPS gain over High is marginal compared to the visual difference. Therefore, the best experience per the measured rows is 1080p Ultra for maximum smoothness, 1440p Ultra for the optimal balance of quality and speed, and 4K High for those prioritizing frame rate over maximum eye candy.

Measured FPS Breakdown

The measured FPS data reveals a consistent performance hierarchy across all resolutions and settings. At 1920x1080, the average FPS ranges from 482 on Low to 314 on Ultra. The Medium preset shows an average of 438 FPS with a minimum of 373 and maximum of 504, indicating very stable frame pacing. High settings at 1080p yield 387 FPS, which is a substantial 73 FPS drop from Medium, showing that the High preset introduces enough additional load to affect performance, though still at an excellent level. At 2560x1440, the averages scale down proportionally: Low hits 321 FPS, Medium 293 FPS (with min/max of 249/336), High 259 FPS, and Ultra 210 FPS. The gap between Medium and High at 1440p is 34 FPS, while the gap between High and Ultra is 49 FPS, suggesting that the Ultra preset's additional effects are more demanding. At 3840x2160, the performance drops are more pronounced: Low delivers 182 FPS, Medium 165 FPS (min 141, max 190), High 146 FPS, and Ultra 119 FPS. The delta between Low and Ultra at 4K is 63 FPS, representing a 35% reduction from the lowest to highest preset. The minimum FPS values are only recorded for the Medium preset at each resolution, with the 4K Medium showing 141 FPS and 1440p Medium showing 249 FPS, while 1080p Medium shows 373 FPS. These minimums indicate that even in the most demanding moments, the combo never drops below 141 FPS at any resolution, confirming that the RTX 3080 has ample headroom for Roblox. The scaling from 1080p to 1440p shows an average FPS reduction of approximately 33% across settings, while the reduction from 1440p to 4K is approximately 44%, demonstrating that the GPU is the primary driver of performance at these resolutions.

CPU Role

The Intel Core i5-10400F provides the processing foundation for this combo, and its specifications indicate a capable mid-range part that does not bottleneck the RTX 3080 in Roblox. The CPU has 6 cores and 12 threads, with a base clock of 2.90 GHz and a boost clock of 4.30 GHz, built on Intel's 14 nm Comet Lake architecture. Its 12 MB of shared L3 cache is modest by modern standards but sufficient for Roblox's workload. The benchmark data shows the CPU achieves a single-thread score of 688 in 3DMark and 1451 in Cinebench R23 single-core, which are the metrics most relevant to Roblox's engine, as the game is known to be sensitive to single-thread performance. The multi-threaded scores are also solid, with a Cinebench R23 multi-core score of 10283 and a Geekbench multi-core score of 6257. The CPU sits at the 68th percentile among all CPUs, with an average benchmark score of 14185, placing it near rivals like the Intel Xeon 6756E (0.2% higher) and AMD EPYC 7552 (0.5% higher). In Roblox, the CPU's 12 threads and 4.30 GHz boost clock ensure that the game's physics and scripting logic are handled efficiently, but the measured FPS data suggests the CPU is not the primary constraint. At 1080p, where GPU load is lower, the CPU must work harder to feed frames, yet the combo still achieves 387 FPS on High settings, indicating that the i5-10400F has enough processing power to keep up. The 2.90 GHz base clock and 4.30 GHz boost clock provide adequate single-thread performance, and the 65W TDP suggests it operates within reasonable thermal limits. The data indicates that the CPU's role is to provide consistent frame delivery without introducing stutters, and the high minimum FPS values (e.g., 373 FPS at 1080p Medium) confirm that the CPU is not causing frame drops.

Resolution Scaling

The FPS scaling from 1080p to 4K reveals how the system's workload shifts between CPU and GPU as resolution increases. At 1080p Low, the average FPS is 482, which drops to 321 at 1440p (a 33% reduction) and then to 182 at 4K (a 43% reduction from 1440p). This pattern shows that the GPU is becoming more heavily utilized as resolution increases, but even at 4K, the frame rates are exceptionally high. The data indicates that at 1080p, the CPU is more involved in frame generation, as the GPU is not fully taxed at 482 FPS, and the difference between Low and Ultra at 1080p (482 to 314, a 35% drop) shows that the GPU still has a significant impact even at this resolution. At 1440p, the scaling from Low to Ultra (321 to 210, a 35% drop) is nearly identical to 1080p, suggesting the GPU remains the dominant factor. At 4K, the Low to Ultra scaling (182 to 119, a 35% drop) is the same percentage, confirming that the RTX 3080's performance scales consistently regardless of resolution. The absolute FPS drop from 1080p to 4K is most pronounced at Low settings (482 to 182, a 62% reduction), while at Ultra settings the drop is from 314 to 119 (a 62% reduction as well). This uniform scaling indicates that the limiting component is the GPU, as the CPU's performance does not degrade with resolution. The i5-10400F maintains its output across all resolutions, allowing the RTX 3080 to be the sole determinant of FPS at each setting. The data shows that the combo is GPU-bound at all resolutions, but the headroom is so large that even at 4K Ultra, the system delivers 119 FPS, which is more than sufficient for Roblox's gameplay. The resolution scaling suggests that users with 1080p or 1440p displays will never see the GPU fully utilized, while 4K users will still enjoy frame rates well above the 60 FPS threshold, making this combo effectively overkill for Roblox but offering a future-proof experience.
