Roblox

Roblox is notoriously light on hardware, and this pairing of the Intel Core i5-9400 with the NVIDIA GeForce RTX 2060 SUPER turns that into an absolute landslide of performance. Across all measured settings and resolutions, the average frame rates are exceptionally high, with the lowest recorded average still sitting at a very playable 73.5 FPS at 4K Ultra. The data indicates that this combo is not merely adequate for Roblox; it is overwhelmingly overqualified, delivering triple-digit frame rates in the vast majority of scenarios and making the game's visual settings the primary lever for performance tuning rather than a source of concern.

Resolution Scaling

The performance drop from 1080p to 4K is significant but remains entirely within the range of high-refresh-rate play. At High settings, the average frame rate falls from 249.4 FPS at 1920x1080 to 166.9 FPS at 2560x1440, a reduction of 33.1%, before settling at 91.3 FPS at 3840x2160. This scaling pattern suggests that while the GPU is starting to feel the load at 4K, the experience is still remarkably fluid.

The most telling data point is at Low settings, where the average FPS drops from 307.7 at 1080p to 204.3 at 1440p and then to 117.3 at 4K. This steep decline at lower graphical presets when moving to 4K indicates that the CPU is capable of feeding the GPU frames at 1080p, but the rendering load at 4K begins to dominate. Conversely, the gap between Low and Ultra at 1080p is 106.5 FPS, showing that the GPU has tremendous headroom at lower resolutions, making the system CPU-bound in that scenario. At 4K, the difference between Low and Ultra narrows to 43.8 FPS, confirming that the GPU becomes the limiting factor as resolution increases, though never to a problematic degree.

How This Combo Ranks

Within the database of 1800 tested combinations for Roblox, this specific pairing of the Core i5-9400 and RTX 2060 SUPER achieves a rank of 1291. This places it in the 71st percentile of all tested systems, meaning it outperforms a substantial majority of other hardware configurations in this specific game. The data shows a system that is firmly in the upper echelon of performance for Roblox, proof of the sheer capability of the RTX 2060 SUPER, which sits in the 63rd percentile of all GPUs.

The ranking is heavily influenced by the GPU's raw power. Its nearest rivals, such as the NVIDIA GeForce RTX 2070 (with a 0.5% higher average benchmark score) and the NVIDIA GeForce GTX TITAN (0.3% higher), are all extremely close in overall compute capability. However, the RTX 2060 SUPER's substantial 8 GB of VRAM and high bandwidth likely contribute to its strong standing in a game that can be sensitive to memory allocation with large user-generated worlds. The Core i5-9400's 50th percentile ranking among all CPUs is not a bottleneck here, as Roblox's engine does not heavily tax its six cores, allowing the GPU to stretch its legs.

Settings Recommendations

The measured data makes a compelling case for using the Ultra preset at 1080p and 1440p, and the High preset at 4K. At 1920x1080, Ultra delivers an average of 201.2 FPS, which is still vastly higher than any standard 60Hz or 144Hz monitor can display, and it offers a 47.9% visual fidelity improvement over High settings in terms of the performance cost. The transition from High to Ultra at 1080p costs 48.2 FPS, but the resulting frame rate is still so high that the visual upgrade is essentially free.

At 2560x1440, Ultra remains the best choice, with an average of 135 FPS. This is well above the threshold for a high-refresh-rate 1440p monitor, making the extra graphical fidelity worthwhile. However, at 3840x2160, the Ultra preset's average of 73.5 FPS is the only measurement that dips below the 90 FPS mark. For a consistently smooth 4K experience, the High preset, at 91.3 FPS, is the optimal balance, sacrificing some visual flair for a 24.2% performance increase over Ultra. The Medium presets offer little benefit, as they provide a minimal frame rate advantage over High while likely reducing visual quality significantly.

GPU Role

The NVIDIA GeForce RTX 2060 SUPER is the clear performance driver in this pairing. Its 8 GB of GDDR6 memory on a 256-bit bus provides 448.0 GB/s of bandwidth, which is more than sufficient for Roblox's asset streaming. The card's high boost clock of 1650 MHz and its 2176 shading units allow it to process the game's simple geometry and effects with immense speed. Its average benchmark score of 19774 places it in the 63rd percentile of all GPUs, and its performance is nearly identical to the RTX 2070, which has an average score of 19680.

The GPU's influence is most evident in the resolution scaling. The 42.7% drop in average FPS across all settings when moving from 1080p to 4K is a direct result of the increased pixel count. The card's raw compute power, rated at 7.181 TFLOPS, ensures it can maintain high frame rates even in the most complex user-generated worlds. Its Passmark G3D score of 16462 corroborates its strong DirectX 11 performance, which is the primary API for Roblox. The GPU's substantial capabilities mean that in this game, the visual preset is more about preference than necessity, as even the most demanding settings are easily handled.

CPU Role

The Intel Core i5-9400 serves as a capable and sufficient foundation for this system. With 6 cores and 6 threads, it provides enough processing power to keep up with the game's physics and logic without becoming a significant bottleneck. Its boost clock of 4.10 GHz is adequate for the single-threaded tasks that often dominate in Roblox, and its Cinebench R23 single-core score of 1125 confirms its competence. The CPU's 9 MB of shared L3 cache helps to reduce latency, ensuring a stable frame pipeline to the GPU.

The data suggests the CPU is the limiting factor only at lower resolutions and settings. At 1080p Low, the average frame rate of 307.7 FPS is likely near the CPU's practical limit for this game engine. This is supported by the fact that the Core i5-9400's average benchmark score of 2305 places it at the 50th percentile of all CPUs, indicating it is a mid-range processor. However, this is not a weakness in this context, as it is never the cause of a poor experience. It provides enough headroom to feed the RTX 2060 SUPER at 1440p and even at 4K, where the GPU's workload takes over as the primary performance limiter.
