Roblox

Intel Core i5-9400 paired with NVIDIA GeForce RTX 2060 delivers overwhelming performance in Roblox, clearing the 60 FPS threshold at every resolution and preset combination recorded in the database. The weakest result is 71 FPS average at 4K Ultra, which still leaves a comfortable margin above the playability threshold. This combination ranks in the 23rd percentile among tested setups, placing it in the lower third of all recorded configurations, yet the game's modest demands mean this ranking does not translate into any practical limitation for Roblox.

Measured FPS Breakdown

At 1920x1080, the Intel Core i5-9400 with RTX 2060 produces exceptional frame rates across all settings. Low settings yield 281.3 FPS average, Medium reaches 253.2 FPS, High drops to 227.6 FPS, and Ultra maintains 180.6 FPS. The scaling from Low to Ultra represents a 35.8% reduction in average frame rate, but even the most demanding preset at this resolution stays far above any competitive display's refresh rate capabilities. The data shows no minimum or maximum frame rate values recorded, so the analysis relies solely on average FPS figures.

Moving to 2560x1440, the same pattern continues with slightly reduced headroom. Low settings produce 188.6 FPS average, Medium delivers 172.2 FPS, High achieves 150.8 FPS, and Ultra settles at 119.6 FPS. The gap between Low and Ultra at this resolution is 69 FPS, a 36.6% drop. This resolution still provides more than double the 60 FPS threshold even at Ultra settings, indicating substantial performance reserves.

At 3840x2160, the RTX 2060 begins to show meaningful load scaling. Low settings record 108.6 FPS average, Medium reaches 98.9 FPS, High delivers 85.7 FPS, and Ultra produces 71 FPS. The Ultra preset at 4K is the only configuration in the entire dataset that approaches the 60 FPS threshold, though it still clears it by 11 FPS. The resolution scaling from 1080p to 4K at Ultra settings shows a 60.7% reduction in average frame rate, from 180.6 FPS down to 71 FPS.

How This Combo Ranks

The database places this CPU and GPU combination at rank 2860 out of 3711 tested combos for Roblox. This translates to a percentile position of approximately 77th from the bottom, meaning roughly 23% of tested configurations rank lower. The ranking reflects the absolute performance of the hardware pair, not the gaming experience, since Roblox's engine does not appear to stress either component to its limits.

The percentileVsAllCpus for the Intel Core i5-9400 is 47, placing it near the median of all CPUs in the database. The percentileVsAllGpus for the RTX 2060 is 58, slightly above the median for all GPUs. When combined, these mid-range components land in the lower quarter of Roblox-specific combo rankings, which suggests that many higher-end configurations achieve substantially higher frame rates, though the practical impact is minimal given the already high absolute performance.

The recorded data shows that the combo rank is driven more by the sheer number of competing high-end systems than by any deficiency in this setup. With 3711 total combos tested, a rank of 2860 means 851 configurations performed worse, while 2860 performed better. The gap between this combo and the top performers likely exceeds what any display can show, given that this setup already exceeds 180 FPS at 1080p Ultra.

Similar Performance Alternatives

The nearest rivals for the Intel Core i5-9400, based on average benchmark scores, include the Intel Core i7-1068NG7 with an average score of 2259, just 0.2% higher. The Intel Core i3-10305 scores 2264, 0.4% higher. On the lower side, the Intel Core i7-10710U scores 2248, 0.3% lower, and the AMD Ryzen 5 PRO 1500 scores 2246, 0.4% lower. These four processors bracket the i5-9400's average score of 2254 within a narrow 0.8% band, indicating that swapping to any of these CPUs would produce nearly identical Roblox performance.

The NVIDIA GeForce RTX 2060 has an average benchmark score of 15290. Its nearest rival, the NVIDIA GeForce GTX 580, scores 15283, a 0% difference. The AMD Radeon 680M scores 15270, 0.1% lower. The NVIDIA GeForce RTX 3050 OEM scores 15199, 0.6% lower, and the AMD Radeon RX 7600 scores 15171, 0.8% lower. All four alternatives sit within 0.8% of the RTX 2060's aggregate score, meaning any of these GPUs would deliver statistically indistinguishable frame rates in Roblox.

For a system builder looking at comparable performance, pairing any of the four rival CPUs with any of the four rival GPUs would produce essentially the same experience in Roblox. The delta percentages are so small that they fall within measurement variance, so the choice between these components comes down to platform features rather than gaming performance.

The Verdict

This PC can run Roblox at every resolution and preset combination recorded in the database, with all twelve measurements clearing the 60 FPS playability threshold. At 1920x1080, the lowest recorded result is 180.6 FPS average at Ultra settings, which is triple the threshold. At 2560x1440, the lowest is 119.6 FPS at Ultra, again nearly double the threshold. Even at 3840x2160, the most demanding configuration, Ultra settings maintain 71 FPS average, which is 11 FPS above the playability line.

The verdictByResolution data confirms that all three resolutions list High, Low, Medium, and Ultra as playable settings. The best settings at each resolution are Ultra, with average FPS of 180.6 at 1080p, 119.6 at 1440p, and 71 at 4K. No resolution requires lowering settings to achieve playable frame rates, and no resolution comes close to dropping below 60 FPS even under the heaviest preset load.

The practical conclusion is that this combination is not just playable but excessively capable for Roblox. Users with high refresh rate monitors at 1080p can expect frame rates well above 200 FPS at lower settings, and even 4K Ultra users will not experience any stutter or frame drops related to hardware limits.

CPU and GPU Roles

The scaling between resolutions and presets reveals that the GPU carries progressively more load as resolution increases, while the CPU remains relatively untaxed. At 1080p, the difference between Low and Ultra is 100.7 FPS (from 281.3 down to 180.6), which represents a 35.8% drop. At 1440p, the same preset swing produces a 69 FPS difference (from 188.6 down to 119.6), a 36.6% drop. At 4K, the swing is 37.6 FPS (from 108.6 down to 71), a 34.6% drop.

The resolution scaling at Ultra settings shows the clearest GPU dependency. Going from 1080p Ultra at 180.6 FPS to 1440p Ultra at 119.6 FPS is a 33.8% reduction. Going from 1440p Ultra to 4K Ultra at 71 FPS is a 40.6% reduction. These percentage drops are consistent with GPU-bound rendering, where pixel count directly dictates frame rate.

The CPU role appears secondary in Roblox. The i5-9400's six cores and six threads, with a boost clock of 4.10 GHz, provide ample single-thread performance for the game's logic. The benchmark scores show a multicore Cinebench R23 result of 6629 and a singlecore result of 935, which are modest by current standards but sufficient for Roblox. The fact that 1080p Low produces 281.3 FPS suggests the CPU is not a limiting factor, as this frame rate exceeds what most CPUs could sustain in more demanding titles.

Best Settings per Resolution

At 1920x1080, the most demanding preset that stays at or above 60 FPS is Ultra, which delivers 180.6 FPS average. This is the recommended setting for this resolution, as it provides the highest visual quality while still maintaining three times the playability threshold. Users can expect a fully smooth experience with no need to compromise on graphical fidelity.

At 2560x1440, Ultra settings again provide the best balance, yielding 119.6 FPS average. This is nearly double the 60 FPS threshold, so there is no reason to drop below Ultra. The margin of 59.6 FPS above the threshold gives ample headroom for scene complexity spikes or background processes.

At 3840x2160, Ultra settings remain the best choice, producing 71 FPS average. This is 11 FPS above the threshold, which is a smaller margin than at lower resolutions but still safe. The data shows that even at 4K Ultra, this combination does not require any settings reduction to maintain playable performance. The progression from 1080p to 4K at Ultra settings is 180.6, 119.6, and 71 FPS respectively, showing a clear but acceptable degradation as resolution increases.
