Roblox

Roblox is a sandbox title that scales in unexpected ways across resolutions, and the data for the Intel Core i5-10400F paired with the NVIDIA GeForce RTX 4070 Ti reveals a system that is heavily CPU-bound at lower resolutions but transitions to a more balanced load at 4K. The measured frames per second (FPS) show an enormous range, from 582 FPS at 1080p Low down to 142.4 FPS at 4K Ultra, which indicates that the bottleneck shifts dramatically depending on the settings and resolution chosen. This analysis walks through the resolution scaling, the combo's ranking among tested systems, the GPU's specific role, and the exact measured FPS breakdown to provide a complete picture of this configuration's performance in Roblox.

Resolution Scaling

The FPS drop from 1080p to 4K is steep, but the pattern reveals the limiting component clearly. At 1080p Low, the system produces 582 FPS. Moving to 1440p Low, that number drops to 393.3 FPS, and at 4K Low, it falls to 225.1 FPS. This represents a 61.3% reduction in FPS from 1080p to 4K at Low settings, which is a massive hit that points directly to the GPU becoming the primary constraint as pixel count rises. The CPU is not the limitation at 4K, as even the lowest preset still yields over 200 FPS, which is far beyond what most displays can refresh.

At Ultra settings, the scaling is even more pronounced. The 1080p Ultra result is 386.1 FPS, 1440p Ultra drops to 259.6 FPS, and 4K Ultra bottoms out at 142.4 FPS. The gap between 1080p and 4K at Ultra is 243.7 FPS, a 63.1% decrease. This consistent drop across all settings presets suggests that the RTX 4070 Ti is doing heavy lifting even in a game that is not traditionally graphically demanding. The data indicates that at 1080p and 1440p, the i5-10400F is holding the system back, as the FPS numbers are extraordinarily high but still limited by the CPU's single-thread performance. At 4K, the GPU takes over as the bottleneck, and the FPS becomes more reasonable relative to the hardware's capabilities.

The intermediate steps confirm this trend. At Medium settings, the drop from 1080p (534.1 FPS) to 1440p (357.7 FPS) is a 33% reduction, and further to 4K (203.4 FPS) is another 43.1% cut. High settings follow the same pattern: 474.8 FPS at 1080p, 318.6 FPS at 1440p, and 179.3 FPS at 4K. The scaling factor between each resolution step is roughly similar, which indicates that the game's rendering load is scaling linearly with pixel count, but the absolute FPS values are so high that the CPU is still the limiting factor until the resolution becomes extreme. For users with high-refresh-rate monitors, this combo delivers playable framerates at every resolution tested, but the headroom at 1080p is limited by the processor.

How This Combo Ranks

The combination of the Intel Core i5-10400F and NVIDIA GeForce RTX 4070 Ti ranks 259 out of 1800 tested combos in Roblox. This places the system in the top 14.4% of all configurations tested for this game. The rank is notable because it is a mid-range CPU from 2020 paired with a high-end GPU from 2023, yet the performance in Roblox is strong enough to beat out many newer, more balanced systems. The data suggests that Roblox is not particularly demanding on multi-core performance, as the game's engine tends to favor single-threaded performance, which is why this older CPU can keep up.

Looking at the CPU's benchmark data, the i5-10400F scores 14168 on average, which places it in the 73rd percentile of all CPUs. Its 3dmark single-thread score is 688, and its passmark single-thread score is 2541. These numbers are modest compared to modern processors, but the actual FPS results in Roblox show that the CPU is capable of feeding the RTX 4070 Ti at 1080p and 1440p. The combo rank of 259 out of 1800 indicates that there are many combinations that perform worse, likely because they pair weaker CPUs with this GPU or use slower memory. The nearest CPU rivals, such as the AMD Ryzen 3 7320C with a deltaPct of -0.8% and the Intel Core i5-8500 with a deltaPct of -1.1%, show that the i5-10400F is right in the middle of its performance class.

The GPU's rank is less relevant here because the combo rank already accounts for the pair. The RTX 4070 Ti sits in the 85th percentile of all GPUs, with an average benchmark score of 44900. Its nearest rivals include the RTX 5090 Mobile at -0.6% and the Intel Arc A730M at -1.5%, which indicates that the desktop RTX 4070 Ti is a top-tier card. The fact that this combo still ranks 259 overall suggests that the CPU is the limiting factor in most scenarios, as the GPU alone would likely rank higher if paired with a faster processor. The data shows that this is a high-performing combo for Roblox, but not the absolute top, as there are 258 other combinations that produce higher average FPS.

GPU Role

The NVIDIA GeForce RTX 4070 Ti is a powerful GPU with 12 GB of GDDR6X memory on a 192-bit bus, providing a bandwidth of 504.2 GB/s. The memory clock runs at 1313 MHz, which translates to 21 Gbps effective, and the core clocks are 2310 MHz base and 2610 MHz boost. These specifications are more than sufficient for Roblox, which is not a graphically intense game. The GPU's role in this combo is to ensure that there is no frame rate ceiling at higher resolutions, and the data confirms that it succeeds. At 4K Ultra, the GPU produces 142.4 FPS, which is still above the 120 Hz refresh rate that many high-end monitors use.

The VRAM capacity of 12 GB is ample for Roblox, as the game's textures and assets are relatively simple. The data does not show any indication of VRAM limitations, as the FPS does not drop disproportionately at higher settings, which would be a sign of memory pressure. The GPU's 80 ROPs and 240 TMUs provide ample fill rate, with a pixel rate of 208.8 GPixel/s and a texture rate of 626.4 GTexel/s. These numbers are far beyond what Roblox requires, so the GPU is never the bottleneck until 4K, and even then, it still delivers over 140 FPS.

The GPU's benchmark scores reinforce its strength. The 3dmark Steel Nomad DX12 score is 5024, and the passmark G3D score is 31624, which places it in the 85th percentile. The Geekbench OpenCL score of 205028 and Vulkan score of 186784 show strong compute performance, but Roblox does not heavily utilize these features. The RTX 4070 Ti's 60 RT cores and 240 tensor cores are present but largely unused in this title, as Roblox does not support ray tracing in a meaningful way. The GPU's role is simply to push pixels fast enough to keep up with the CPU at lower resolutions, and it does so effectively, as evidenced by the 582 FPS at 1080p Low.

Measured FPS Breakdown

At 1080p, the measured FPS ranges from 386.1 at Ultra to 582 at Low. The Medium preset yields 534.1 FPS, and High produces 474.8 FPS. The difference between Low and Ultra at 1080p is 195.9 FPS, which is a 33.6% drop. This indicates that the Ultra settings impose a significant load on the GPU, but the CPU is still able to maintain high framerates. The data shows that this combo is capable of exceeding 500 FPS at 1080p with lower presets, which is ideal for competitive play on 360 Hz monitors. The High preset at 474.8 FPS is still far above what any mainstream display can show, making it a viable option for most users.

At 1440p, the FPS drops but remains exceptionally high. Low produces 393.3 FPS, Medium 357.7 FPS, High 318.6 FPS, and Ultra 259.6 FPS. The gap between Low and Ultra at 1440p is 133.7 FPS, a 34% reduction. This resolution is the sweet spot for the combo, as it delivers framerates that are still above 240 FPS on Medium and High, which is sufficient for the fastest gaming monitors available. The 1440p Ultra result of 259.6 FPS is still above 240 FPS, meaning that users can enable maximum settings and still enjoy a smooth experience on high-refresh-rate displays.

At 4K, the FPS becomes more moderate. The Low preset yields 225.1 FPS, Medium 203.4 FPS, High 179.3 FPS, and Ultra 142.4 FPS. The difference between Low and Ultra at 4K is 82.7 FPS, a 36.7% reduction. This is the only resolution where the GPU is clearly the limiting factor, as the CPU has more headroom. The 4K Ultra result of 142.4 FPS is still above 120 FPS, making it suitable for 120 Hz 4K displays, but it does not reach the 144 Hz or 165 Hz targets that some users prefer. The data shows that the combo can handle 4K gaming in Roblox, but users will need to choose between lower settings for higher FPS or Ultra settings for visual fidelity.

Settings Recommendations

Based on the measured FPS data, the best experience depends on the user's display refresh rate and resolution preference. For 1080p users, the High preset at 474.8 FPS is the recommended choice, as it offers a good balance between visual quality and performance. The Ultra preset at 386.1 FPS is also viable, but the visual difference between High and Ultra in Roblox is minimal, and the extra 88.7 FPS from High is more valuable for competitive play. The Low and Medium presets at 582 and 534.1 FPS, respectively, are only recommended for users with 500 Hz monitors, which are rare.

For 1440p users, the Medium preset at 357.7 FPS is the sweet spot, as it delivers framerates that exceed the refresh rate of most 240 Hz monitors. The High preset at 318.6 FPS is also excellent, and the difference of 39.1 FPS between Medium and High is noticeable but not critical. The Ultra preset at 259.6 FPS is still above 240 FPS, so users with 240 Hz displays can enable Ultra without sacrificing smoothness. The Low preset at 393.3 FPS is unnecessary, as it does not provide a meaningful FPS benefit over Medium for most users.

For 4K users, the Medium preset at 203.4 FPS is the best choice, as it offers framerates that are above 144 Hz and close to 200 FPS. The High preset at 179.3 FPS is also viable for 144 Hz displays, but the Medium preset provides a 24.1 FPS advantage. The Ultra preset at 142.4 FPS is only recommended for users with 120 Hz displays, as it does not reach 144 FPS. The Low preset at 225.1 FPS is the highest FPS option, but the visual quality reduction is significant, and the Medium preset is a better trade-off. Overall, the data suggests that Medium or High settings are the optimal choices across all resolutions, with Ultra reserved for users with lower refresh rate displays.
