Roblox

Roblox is a game that scales dramatically with the hardware driving it, and the measured data for the Intel Core i5-10400F paired with the NVIDIA GeForce RTX 4070 Ti SUPER reveals a system that is heavily constrained by the CPU at lower resolutions while the GPU becomes more relevant at 4K. The benchmark results show a clear pattern: as resolution drops, frame rates soar to levels that far exceed typical display refresh rates, indicating that the processor is the primary bottleneck in most scenarios. At 1920x1080 with Low settings, the combo produces 582.2 FPS, but at 3840x2160 with Ultra settings, it falls to 146.1 FPS. The data suggests that the RTX 4070 Ti SUPER has ample headroom in this title, and the i5-10400F's six cores are the limiting factor for pushing beyond the already impressive numbers.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial but not uniform across quality presets, which tells a story about where the workload shifts. At Low settings, the average frame rate falls from 582.2 FPS at 1920x1080 to 224.7 FPS at 3840x2160, a reduction of approximately 61%. This steep decline indicates that even at the lowest graphical preset, the GPU is being fed more pixels at 4K, and the rendering load increases enough to bring the frame rate down to a level that is still very high but far from the CPU-bound ceiling. For High settings, the drop is from 475.8 FPS to 182.3 FPS, a similar percentage decrease, suggesting that the scaling pattern holds across presets.

The relationship between resolution and performance becomes clearer when looking at the 1440p data. At 2560x1440 with Low settings, the combo hits 395.8 FPS, which is 68% of the 1080p Low result. This indicates that the GPU is starting to take on more work, but the CPU still has significant influence. The most telling data point is at 4K Ultra, where the average FPS drops to 146.1, which is the lowest measured value in the entire table. This suggests that at the highest resolution and quality settings, the RTX 4070 Ti SUPER is finally being utilized more fully, and the frame rate is still high enough to suggest that the GPU is not the sole limiting factor. The data implies that this game is exceptionally well-optimized for high frame rates, and the scaling from 1080p to 4K shows a smooth degradation rather than a cliff, indicating that the system has balanced capabilities for a title that prioritizes frame rate.

GPU Role

The NVIDIA GeForce RTX 4070 Ti SUPER brings a substantial set of specifications to Roblox, and the measured FPS data shows that it is rarely pushed to its limits. With 16 GB of GDDR6X memory on a 256-bit bus, the card has a bandwidth of 672.3 GB/s, which is more than sufficient for a game like Roblox that does not typically require massive memory throughput. The boost clock of 2610 MHz and the 8448 shading units provide raw compute power that is evident in the high frame rates, but the data suggests that the GPU is often idling or waiting for the CPU to send instructions. The benchmark scores for the GPU, such as a Passmark G3D score of 31811 and a 3DMark Steel Nomad DX12 score of 5569, confirm that this is a high-end card, but in Roblox, its role is more about maintaining consistent frame rates rather than pushing boundaries.

At 1080p Low, the GPU is clearly not the bottleneck, as the 582.2 FPS result is likely beyond what most displays can even show. The VRAM capacity is also not a concern at any resolution or setting, as the game's assets are relatively simple, and 16 GB is overkill for this workload. The card's architecture, Ada Lovelace, and its process node of 5 nm contribute to its efficiency, but the data indicates that the GPU's performance in Roblox is more about headroom than raw exertion. The fact that the 4K Ultra result is 146.1 FPS, which is still well above playable thresholds, suggests that the GPU can handle the most demanding settings without breaking a sweat, and the limiting factor is more likely the CPU's ability to maintain a high frame rate. The GPU's percentile rank of 86 among all GPUs and its average benchmark score of 48704 place it in the upper echelon, but its performance in this specific game is constrained by the rest of the system.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor with a base clock of 2.90 GHz and a boost clock of 4.30 GHz, and the benchmark data clearly shows that it is the dominant factor in Roblox performance. The measured FPS at 1080p Low is 582.2, which is an extraordinarily high number that indicates the CPU is processing game logic and physics at a very rapid pace. The CPU's multi-threaded capabilities, as evidenced by a Cinebench R23 multicore score of 10297 and a Passmark multithread score of 12115, provide enough parallel processing power to feed the GPU with data. However, the single-thread performance, with a Geekbench singlecore score of 1454 and a Passmark single thread score of 2541, is what matters most for a game like Roblox, which often relies on a few primary threads.

The data shows that when the resolution is increased, the FPS drops, which suggests that the CPU is still providing a high frame rate ceiling, but the GPU is taking on more of the rendering load. The drop from 582.2 FPS at 1080p Low to 395.8 FPS at 1440p Low is a 32% reduction, which is significant but still indicates that the CPU is not fully saturated. The core count of 6 and the 12 MB of shared L3 cache are adequate for Roblox, but the architecture, Comet Lake, is older compared to newer designs, and the 14 nm process node means it runs at a higher TDP of 65 W relative to its performance. The CPU's percentile rank of 73 among all CPUs and its average benchmark score of 14168 show that it is a mid-range part, but in this game, it is able to achieve frame rates that rival much more expensive processors. The data implies that the i5-10400F is the main reason why the frame rates are so high, and any upgrade to a faster CPU would likely yield even higher numbers, but the current combo already delivers exceptional performance.

Settings Recommendations

The measured data provides a clear picture of which settings offer the best balance between visual quality and frame rate. For players with a 1080p display, the High preset at 475.8 FPS is an excellent choice, as it offers a significant boost in visual fidelity over Low (582.2 FPS) while still maintaining a frame rate that is above any practical refresh rate. The Ultra preset at 390.2 FPS is also viable, but the difference between High and Ultra is not worth the 85.6 FPS loss for most users. At 1440p, the High preset at 320.6 FPS is the sweet spot, as it provides a smooth experience on high-refresh-rate monitors, while the Low preset at 395.8 FPS is only for competitive play where every frame matters. The Medium preset at 359.9 FPS is a balanced option, but High is generally preferred for the visual improvements.

For 4K gaming, the situation is different. The Low preset at 224.7 FPS is the only setting that guarantees a frame rate above 200 FPS, but the Medium preset at 207.1 FPS is close and offers better visuals. The High preset at 182.3 FPS is still excellent and is the recommended choice for most 4K displays, as it provides a high-quality image with a frame rate that exceeds 144 Hz. The Ultra preset at 146.1 FPS is the most demanding, and while it is still playable, it sacrifices frame rate for marginal graphical gains. The data suggests that the best experience is achieved by using the High preset at any resolution, as it offers the best balance of performance and visual quality, with the added benefit of being consistent across all three resolutions.

Measured FPS Breakdown

The measurement table shows a complete matrix of performance across three resolutions and four quality presets. At 1920x1080, the Low setting yields 582.2 FPS, Medium yields 539.0 FPS, High yields 475.8 FPS, and Ultra yields 390.2 FPS. The progression is logical, with each increase in quality reducing the frame rate by a similar margin. At 2560x1440, the numbers are 395.8 FPS for Low, 359.9 FPS for Medium, 320.6 FPS for High, and 261.0 FPS for Ultra. The gap between Low and Ultra at 1440p is 134.8 FPS, which is a larger absolute drop than at 1080p, but the percentage difference is similar. At 3840x2160, the Low setting produces 224.7 FPS, Medium produces 207.1 FPS, High produces 182.3 FPS, and Ultra produces 146.1 FPS.

The data shows a consistent pattern where the difference between Low and Medium is smaller than the difference between High and Ultra. For example, at 1080p, the drop from Low to Medium is 43.2 FPS, while the drop from High to Ultra is 85.6 FPS. This suggests that the Ultra preset includes effects that are significantly more demanding on the GPU, while the lower presets are more CPU-bound. The 4K results are particularly interesting, as the drop from Low to Ultra is 78.6 FPS, which indicates that the GPU is handling the increased pixel count and the graphical effects are adding a significant load. Overall, the measured FPS values are remarkably high, with even the lowest result at 4K Ultra being above 144 FPS, which means this combo can drive high-refresh-rate displays at any resolution without issue.

How This Combo Ranks

The combo of Intel Core i5-10400F and NVIDIA GeForce RTX 4070 Ti SUPER achieves a rank of 212 out of 1800 tested combos in Roblox, which places it in the top 11.8% of all systems. This is a strong result for a processor that was released in 2020 and is now considered a mid-range part, paired with a high-end GPU. The rank indicates that this system outperforms the vast majority of other configurations, likely due to the game's strong CPU dependency and the i5-10400F's ability to deliver high single-threaded performance. The GPU's contribution is also significant, as its high memory bandwidth and compute power ensure that there is no GPU-related bottleneck at lower resolutions.

The rank of 212 means that there are 211 other combos that perform better, which likely include newer processors with higher boost clocks or more cores. However, the data shows that this combo is not far off the top, and the frame rates are so high that the difference between rank 212 and rank 1 is likely imperceptible in practice. The CPU's nearest rivals in terms of average benchmark score include the AMD EPYC 7552, which is a server processor, and the Intel Core i5-8500, which is an older part, and this combo outperforms them in Roblox due to its higher boost clock and better single-thread performance. The GPU's nearest rivals, such as the NVIDIA CMP 50HX, have similar average scores, but the RTX 4070 Ti SUPER's architecture is better suited for gaming workloads. Overall, the ranking confirms that this is a well-balanced system for Roblox, with the CPU providing the necessary frame rate ceiling and the GPU ensuring consistent performance across all settings.
