Similar Performance Alternatives

The Intel Core i5-11400F sits in a dense performance cluster. Its average benchmark score of 17,177 places it near several processors with almost identical output. The AMD EPYC 7H12 scores 17,120, a difference of only 0.3 percent. The Intel Core i5-12450H scores 17,239, which is 0.4 percent higher than the i5-11400F. The AMD Ryzen 3 PRO 8300G reaches 17,278, a 0.6 percent advantage. The Intel Core Ultra 7 164U scores 17,074, trailing by 0.6 percent. In practical terms, any of these CPUs would deliver nearly indistinguishable frame rates in Roblox, since the game rarely stresses multi-core performance beyond a few threads. The i5-11400F has six cores and twelve threads, with a boost clock of 4.40 GHz, which is more than sufficient for the game’s typical workload.

The NVIDIA GeForce RTX 4070 also has close rivals. Its average benchmark score is 37,648. The NVIDIA Tesla P4 scores 37,628, a negligible 0.1 percent difference. The AMD Radeon RX Vega 56 scores 37,507, trailing by 0.4 percent. The NVIDIA GeForce RTX 4080 Mobile scores 38,135, which is 1.3 percent higher. The AMD Radeon PRO W6400 scores 37,157, a 1.3 percent deficit. For Roblox, these differences are well within the margin of run-to-run variance. The RTX 4070’s 12 GB of GDDR6X memory and 504.2 GB/s bandwidth are far beyond what Roblox requires, so any of these GPUs would behave similarly in this specific title.

The percentile rankings reinforce this picture. The i5-11400F sits at the 71st percentile among all CPUs, while the RTX 4070 sits at the 81st percentile among all GPUs. The measured combination ranks 861 out of 3,711 possible CPU-GPU pairs for Roblox, placing it comfortably in the upper quarter of tested configurations. None of the nearest rivals would change the overall experience in any meaningful way.

CPU and GPU Roles

Roblox is a sandbox game that relies heavily on single-threaded performance for its core simulation logic, but the rendering load can shift the balance. The recorded data shows that the GPU becomes the dominant factor as resolution increases, while the CPU remains relevant at lower resolutions and higher frame rates.

At 1920x1080 with Low settings, the average frame rate reaches 501 FPS. This is a CPU-bound scenario, as the RTX 4070 is capable of far more than 500 FPS in light rendering tasks, but the i5-11400F’s single-thread score of 868 in 3dMark single-thread and 2,024 in Cinebench R23 single-core sets the ceiling. Moving from Low to Ultra at 1080p drops the average to 325.9 FPS, a reduction of 35 percent. That drop is primarily due to increased pixel shading and geometry work, which engages more of the GPU.

At 2560x1440, the pattern continues. Low settings produce 336.2 FPS, while Ultra produces 217.2 FPS. The gap between Low and Ultra is 35 percent, similar to 1080p. The GPU is now doing more work per pixel, but the frame rates remain high enough that the CPU still matters for the upper bound.

At 3840x2160, the GPU becomes clearly dominant. Low settings yield 192.3 FPS, while Ultra drops to 122.7 FPS. The reduction from Low to Ultra is 36 percent, but the absolute frame rates are lower, indicating that the RTX 4070 is now the primary limiter. The CPU has less headroom to matter because the GPU takes longer to render each frame.

Scaling across resolutions tells the same story. At Ultra settings, moving from 1080p to 1440p reduces the average from 325.9 to 217.2 FPS, a 33 percent drop. Moving from 1440p to 4K reduces it further to 122.7 FPS, a 43 percent drop. These are GPU-bound scaling patterns. At Low settings, moving from 1080p to 1440p goes from 501 to 336.2 FPS, a 33 percent drop, and then to 192.3 FPS at 4K, a 43 percent drop. The proportional scaling is consistent, which suggests that the game’s rendering pipeline scales predictably with resolution.

For players using 1080p or 1440p monitors with high refresh rates, the CPU matters more because the GPU can produce frame rates well above 300 FPS, and the i5-11400F’s single-thread performance becomes the bottleneck. For 4K users, the RTX 4070 is the limiting factor, and the CPU has ample headroom.

Measured FPS Breakdown

The database contains measured average frame rates for three resolutions and four settings presets. Minimum and maximum frame rates were not recorded, so the analysis relies on averages.

At 1920x1080, Low settings produce an average of 501 FPS. Medium settings reduce this to 458.6 FPS, a 8.5 percent drop. High settings come in at 401.6 FPS, a 12.4 percent drop from Medium. Ultra settings produce 325.9 FPS, an 18.9 percent drop from High. The stepwise reduction is consistent, with each preset tier adding more visual effects that cost frame rate.

At 2560x1440, Low settings average 336.2 FPS. Medium settings reach 308 FPS, an 8.4 percent drop. High settings average 271.4 FPS, an 11.9 percent drop from Medium. Ultra settings produce 217.2 FPS, a 20 percent drop from High. The pattern mirrors 1080p, but the absolute values are lower due to the increased pixel count.

At 3840x2160, Low settings average 192.3 FPS. Medium settings reach 173.4 FPS, a 9.8 percent drop. High settings average 153.6 FPS, an 11.4 percent drop from Medium. Ultra settings produce 122.7 FPS, a 20.1 percent drop from High. The relative scaling across presets is similar at every resolution, but 4K pushes the GPU hard enough that even Ultra stays well above the 60 FPS threshold.

The largest single drop occurs when moving from High to Ultra at 1440p and 4K, where the frame rate falls by approximately 20 percent. This suggests that the Ultra preset introduces a particularly demanding effect, such as additional shadow quality or post-processing, that disproportionately impacts performance.

The Verdict

This combination of Intel Core i5-11400F and NVIDIA GeForce RTX 4070 can run Roblox at every resolution and preset tested, with all averages exceeding 60 FPS by a substantial margin. The verdict data confirms that all four settings presets are playable at each of the three resolutions.

At 4K, the best playable setting is Ultra, which averages 122.7 FPS. This is more than double the playable threshold of 60 FPS. Even the most demanding preset leaves significant headroom, so players can enable maximum visual quality without concern. The gap between Ultra at 4K and the threshold is 62.7 FPS, which means there is no scenario where this hardware struggles in Roblox.

At 1440p, Ultra settings average 217.2 FPS. This is suitable for high-refresh-rate monitors, including 144 Hz and even 240 Hz displays. The frame rate is 3.6 times the playable threshold. Low settings at this resolution reach 336.2 FPS, which would benefit competitive players seeking maximum responsiveness.

At 1080p, Ultra settings average 325.9 FPS. Low settings reach 501 FPS, which is near the limit of most high-refresh monitors. The i5-11400F’s single-thread performance becomes the limiting factor at this resolution, as the GPU is capable of rendering frames faster than the CPU can feed it. Even so, the experience is smooth and responsive at any setting.

The data indicates no playability concerns for Roblox. There are no recorded minimum frame rates, but the averages are so far above the threshold that typical stutters or frame-time spikes would need to be severe to drop below 60 FPS. Given the game’s relatively simple rendering requirements, this is unlikely.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 122.7 FPS. Since Ultra is the highest preset available, it is the recommended choice. The frame rate is high enough that no compromise is necessary.

At 2560x1440, Ultra settings also deliver the best experience, with an average of 217.2 FPS. This is well above the threshold and suitable for high-refresh displays. There is no reason to lower the preset at this resolution.

At 1920x1080, Ultra settings produce an average of 325.9 FPS. This is the maximum quality preset and remains far above the 60 FPS threshold. Players with 240 Hz or 360 Hz monitors might prefer Low settings for the 501 FPS average, but for visual quality, Ultra is fully playable.

In all cases, the database indicates that the Intel Core i5-11400F and NVIDIA GeForce RTX 4070 combination has no playability constraints in Roblox. The recorded frame rates are consistently high across every resolution and preset, with no scenario approaching the 60 FPS minimum. The only practical consideration is whether a display can actually show the frame rates produced, as 4K Ultra at 122.7 FPS exceeds the refresh rate of many monitors, and 1080p Low at 501 FPS exceeds the capabilities of all but the most specialized gaming displays. For standard use, enabling Ultra at any resolution is the optimal choice.
