Roblox

The Intel Core i5-10400F paired with the NVIDIA GeForce RTX 4070 delivers exceptionally high frame rates in Roblox across all tested resolutions. The recorded data shows that every preset at every resolution clears the 60 FPS playability threshold by a wide margin, making this combination an overwhelmingly capable setup for this sandbox title. The following analysis breaks down the optimal settings, performance scaling, and component roles based strictly on the measured database results.

Best Settings per Resolution

At 3840x2160, the most demanding preset that maintains an average of at least 60 FPS is Ultra, which runs at an average of 124 FPS. This is the highest visual quality option available, and the data confirms it remains far above the playability threshold. Lower presets at this resolution, including High at 155.9 FPS, Medium at 171 FPS, and Low at 191.7 FPS, all also clear the threshold, but Ultra is the recommended choice for maximum fidelity while keeping performance headroom.

At 2560x1440, Ultra settings again deliver the best balance, producing an average of 218.8 FPS. This is more than triple the 60 FPS threshold, so there is no need to compromise on visual quality. High runs at 270 FPS, Medium at 307.8 FPS, and Low at 338.9 FPS, but the Ultra preset is clearly the right pick for this resolution.

At 1920x1080, the Ultra preset achieves an average of 327.8 FPS, which is the highest fidelity option and still vastly exceeds the playability bar. High runs at 402.1 FPS, Medium at 456.1 FPS, and Low at 502.4 FPS, but with such massive margins, the Ultra preset is the obvious choice. In every resolution, the data shows that the most demanding setting (Ultra) is the recommended configuration, as it never drops near the 60 FPS floor.

Measured FPS Breakdown

The recorded data provides average frame rates only, with no minimum or maximum values captured for any configuration. At 1920x1080, the frame rates range from 327.8 FPS on Ultra up to 502.4 FPS on Low. The Medium preset produces 456.1 FPS, and High produces 402.1 FPS. The scaling from Low to Ultra shows a consistent reduction: Low to Medium drops by 46.3 FPS, Medium to High drops by 54 FPS, and High to Ultra drops by 74.3 FPS. This indicates that each successive quality tier has a measurable performance cost, though all remain extremely high.

At 2560x1440, the averages are 338.9 FPS on Low, 307.8 FPS on Medium, 270 FPS on High, and 218.8 FPS on Ultra. The difference between Low and Ultra is 120.1 FPS. The step from Medium to High is 37.8 FPS, and from High to Ultra is 51.2 FPS. Compared to 1080p, the same settings at 1440p show a reduction of 163.5 FPS on Low, 148.3 FPS on Medium, 132.1 FPS on High, and 109 FPS on Ultra.

At 3840x2160, the averages are 191.7 FPS on Low, 171 FPS on Medium, 155.9 FPS on High, and 124 FPS on Ultra. The spread between the lowest and highest settings is 67.7 FPS. Moving from 1440p to 4K, the reductions are 147.2 FPS on Low, 136.8 FPS on Medium, 114.1 FPS on High, and 94.8 FPS on Ultra. Across all resolutions, the Ultra preset exhibits the smallest absolute drop when increasing resolution, suggesting that the GPU has substantial headroom even at the highest settings.

Similar Performance Alternatives

The CPU and GPU each have nearby rivals in the database that would produce comparable overall system behavior. For the Intel Core i5-10400F, the nearest competitor is the Intel Xeon 6756E, which has an average score of 14163, a delta of 0.2% relative to the i5-10400F's score. The AMD EPYC 7552 is also close with an average score of 14115 and a delta of 0.5%. On the other side, the Intel Core 7 160UL scores 14232, which is 0.3% higher, and the AMD Ryzen 3 7320C scores 14277, which is 0.6% higher. These deltas are all within a fraction of a percent, meaning any of these CPUs would deliver nearly identical CPU-bound performance in Roblox.

For the NVIDIA GeForce RTX 4070, the nearest rival is the NVIDIA Tesla P4 with an average score of 37628 and a delta of 0.1%. The AMD Radeon RX Vega 56 scores 37507, a delta of 0.4%, while the NVIDIA GeForce RTX 4080 Mobile scores 38135, which is 1.3% higher. The AMD Radeon PRO W6400 scores 37157, a delta of 1.3% lower. These small deltas indicate that swapping the RTX 4070 for any of these GPUs would result in nearly identical frame rates in this game. The data shows that the RTX 4070 sits comfortably in the middle of this cluster, with no rival exceeding a 1.3% performance difference.

The Verdict

The verdict by resolution is unambiguous: this PC can run Roblox at every tested resolution and every tested preset, all above the 60 FPS playability threshold. At 3840x2160, the playable settings include High, Low, Medium, and Ultra, with the best settings being Ultra at an average of 124 FPS. At 2560x1440, all four presets are playable, with Ultra again recommended at 218.8 FPS. At 1920x1080, Ultra is the best setting, running at 327.8 FPS.

There is no configuration in the measured data where the frame rate falls below 124 FPS, which is more than double the 60 FPS threshold. The lowest recorded average, 124 FPS at 4K Ultra, still provides a substantial margin for smooth gameplay. The data strongly indicates that this combo is not merely playable but overqualified for Roblox, with the ability to run the highest visual settings at high refresh rates even at 4K resolution.

How This Combo Ranks

In the database of tested combinations for Roblox, this specific pairing of Intel Core i5-10400F and NVIDIA GeForce RTX 4070 ranks 846 out of 3711 combos. This places it in the top 22.8% of all recorded systems. The rank reflects the overall performance level, and given that the measured frame rates are all far above the playability threshold, the relative standing confirms that this is a high-performing configuration for this game.

The rank is a composite measure that accounts for the combined capabilities of both components. With the CPU sitting at the 68th percentile among all CPUs and the GPU at the 81st percentile among all GPUs, the combined rank of 846 out of 3711 is consistent with a system that outperforms the majority of tested setups. The large gap between this combo's frame rates and the 60 FPS threshold suggests that its rank is driven more by raw performance than by mere adequacy.

CPU and GPU Roles

The scaling data reveals how the CPU and GPU each contribute to performance in Roblox as resolution changes. At 1920x1080, the frame rates are extraordinarily high, ranging from 327.8 FPS to 502.4 FPS depending on settings. At this resolution, the workload is less demanding on the GPU, so the CPU's role becomes more prominent. The i5-10400F has a passmark single-thread score of 2541 and a passmark multithread score of 12115, which are sufficient to drive these high frame rates without becoming a bottleneck.

As resolution increases to 2560x1440 and then to 3840x2160, the frame rates drop significantly, indicating a shift toward GPU-bound performance. The RTX 4070, with its passmark G3D score of 26927 and 12 GB of GDDR6X memory, handles the increased pixel workload, but the data shows that even at 4K Ultra, the average remains at 124 FPS. The transition from 1080p to 4K at Ultra settings reduces the average from 327.8 FPS to 124 FPS, a drop of 203.8 FPS, which is primarily attributable to the GPU's rendering load.

The CPU's performance is relatively consistent across resolutions because Roblox's simulation and logic load does not scale with pixel count. The i5-10400F's 6 cores and 12 threads, along with its 12 MB of shared L3 cache, provide stable processing power. The GPU, however, sees a much larger relative workload increase as resolution rises. This is evident in the frame rate gaps: at 1080p, the difference between Low and Ultra is 174.6 FPS, while at 4K, the same difference is only 67.7 FPS. This narrowing gap indicates that at higher resolutions, the GPU becomes the limiting factor, and the CPU has ample headroom to keep up.

At 1920x1080, the combination is clearly CPU-limited in the sense that the GPU can render frames faster than the CPU can feed it, but the measured frame rates are so high that this does not impact playability. At 3840x2160, the GPU is the dominant factor, as evidenced by the lower absolute frame rates and the smaller spread between settings. The data supports the conclusion that for Roblox, the RTX 4070 is the primary driver of performance at 4K, while the i5-10400F is more than adequate at all resolutions, with neither component causing a significant bottleneck that would compromise the 60 FPS target.
