Roblox

The Intel Core i5-11400F paired with the NVIDIA GeForce RTX 3070 Ti delivers exceptional performance in Roblox, a Sandbox title from 2006. The measured frame rates show that this combination is capable of pushing well beyond the refresh rates of standard monitors, even at 4K resolution. The data indicates that the limiting factor shifts between the CPU and GPU depending on the resolution and quality settings selected, with the balance favoring extreme high-speed gameplay at lower resolutions.

Resolution Scaling

The FPS progression from 1080p to 4K reveals a classic pattern where the GPU becomes progressively more dominant as pixel count increases. At 1920x1080 with Low settings, the combo achieves 438.6 FPS, but this drops to 290.3 FPS at 2560x1440, and further to 163.6 FPS at 3840x2160. This represents a 62.7% reduction in frame rate from 1080p to 4K at Low settings, indicating that while the RTX 3070 Ti is powerful, the sheer pixel throughput at 4K imposes a significant load.

The scaling behavior changes with settings. At Ultra quality, the frame rate falls from 282.7 FPS at 1080p to 190.5 FPS at 1440p, and then to 105.3 FPS at 4K. The drop from 1080p to 4K at Ultra is 62.8%, nearly identical to the Low setting drop. This consistency suggests that the rendering pipeline in Roblox scales uniformly with resolution regardless of the quality preset, pointing to a fill-rate or bandwidth constraint rather than a shader-complexity bottleneck.

Medium settings show a similar trend: 396.2 FPS at 1080p, 261.9 FPS at 1440p, and 149.9 FPS at 4K. The 1080p-to-4K reduction here is 62.2%. High settings yield 348.6 FPS, 233.7 FPS, and 131.1 FPS respectively, a 62.4% reduction. The uniformity across settings—all falling within a narrow 62.2% to 62.8% range—strongly indicates that the limiting component at 4K is the GPU's pixel processing capability, not the CPU or memory subsystem.

At 1080p, the CPU begins to play a larger role. The difference between Low (438.6 FPS) and Ultra (282.7 FPS) is 155.9 FPS, a 35.5% gap. This spread narrows at 1440p (290.3 vs 190.5, a 34.4% gap) and at 4K (163.6 vs 105.3, a 35.6% gap). The relative consistency of this settings-based delta across resolutions suggests that the CPU is not the primary limiter even at 1080p; instead, the GPU's ability to handle increased shader work at higher quality presets drives the difference.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor from the Rocket Lake architecture, built on Intel's 14 nm process. Its base clock of 2.60 GHz boosts to 4.40 GHz, and it features 12 MB of shared L3 cache alongside 512 KB of L2 and 80 KB of L1 per core. The processor scores 868 in 3dmark_single_thread and 2029 in cinebench_r23_singlecore, indicating solid single-threaded performance that is critical for game logic.

In Roblox, the CPU's role appears secondary to the GPU at most settings, given the extremely high frame rates observed. At 1080p Low, the 438.6 FPS figure suggests the CPU can feed the GPU with draw calls and physics updates quickly enough to avoid becoming a bottleneck. The processor's 12 threads handle the game's multithreaded workloads, with 3dmark_max_threads scoring 5652 and cinebench_r23_multicore reaching 14372, showing robust scaling across cores.

However, the CPU does show its limits when compared to its nearest rivals. The i5-11400F has an average benchmark score of 17181, which is essentially tied with the AMD Ryzen 7 5700U (17189, 0% delta) and the Intel Core i7-1260P (17212, -0.2% delta). This places it in the 75th percentile of all CPUs, meaning it outperforms three-quarters of tested processors. The single-thread score of 868 in 3dmark is particularly relevant for Roblox, which relies heavily on a primary game thread for player input and world state updates.

The CPU's memory bandwidth of 51.2 GB/s via dual-channel DDR4 could theoretically limit performance in scenarios with many entities, but the measured FPS data does not show signs of such a constraint. The processor's 65 W TDP suggests efficient operation, and its PCIe Gen 4 support with 20 lanes provides ample bandwidth for the RTX 3070 Ti. Given that the combo achieves over 280 FPS even at Ultra settings on 1080p, the CPU is clearly not a limiting factor in typical Roblox gameplay.

Measured FPS Breakdown

The measured data provides a complete matrix of performance across three resolutions and four quality settings. At 1920x1080, the average frame rates are: Low at 438.6 FPS, Medium at 396.2 FPS, High at 348.6 FPS, and Ultra at 282.7 FPS. The spread from Low to Ultra is 155.9 FPS, with each step up in quality costing roughly 9-19% performance. The step from High to Ultra is the largest single drop, from 348.6 to 282.7 FPS, a 18.9% reduction.

At 2560x1440, the performance remains robust: Low delivers 290.3 FPS, Medium 261.9 FPS, High 233.7 FPS, and Ultra 190.5 FPS. The gap between Low and Ultra here is 99.8 FPS, a 34.4% reduction. The relative ordering remains consistent, with Ultra always being the most demanding. The 1440p results show that this combo can comfortably drive high-refresh-rate 1440p monitors even at maximum quality settings.

At 3840x2160, the frame rates are lower but still playable: Low produces 163.6 FPS, Medium 149.9 FPS, High 131.1 FPS, and Ultra 105.3 FPS. The Ultra setting at 4K is the only configuration that dips below 120 FPS, but it still maintains a smooth 105.3 FPS average. The difference between Low and Ultra at 4K is 58.3 FPS, a 35.6% reduction, which mirrors the percentage drops seen at lower resolutions.

Comparing settings across resolutions, the delta between Low and Ultra remains relatively constant: 35.5% at 1080p, 34.4% at 1440p, and 35.6% at 4K. This consistency confirms that the quality settings impose a similar relative cost regardless of resolution, and the absolute FPS values scale down as pixel count increases. The data shows that no setting combination produces frame rates below 100 FPS, indicating that this combo is suitable for high-refresh-rate displays at any resolution up to 4K.

How This Combo Ranks

This Intel Core i5-11400F + NVIDIA GeForce RTX 3070 Ti combination ranks 727th out of 1800 tested combos in Roblox, placing it in the 59.6th percentile of all configurations. This ranking reflects a strong but not top-tier position, suggesting that while the combo delivers excellent performance, there are 726 other pairings that achieve higher frame rates in this specific game.

The ranking makes sense given the hardware's characteristics. The RTX 3070 Ti, with its 6144 shading units and 8 GB of GDDR6X memory on a 256-bit bus, is a high-end GPU that ranks in the 74th percentile of all GPUs. Its nearest rivals include the AMD Radeon RX 6700 (avgScore 31112, -0.8% delta) and the NVIDIA Quadro M5000 (31142, -0.9% delta), showing it is competitive with upper-midrange cards. The GPU's 21.75 TFLOPS FP32 performance and 608.3 GB/s memory bandwidth are substantial, but Roblox's relatively simple geometry and lighting may not fully utilize this power.

The CPU's 75th percentile ranking among all processors, with an average score of 17181, is nearly identical to its nearest rivals—the AMD Ryzen 7 5700U (17189) and Intel Core i7-1260P (17212). This parity means the CPU is not a distinguishing factor in the combo's ranking; instead, the GPU's performance relative to other tested cards likely determines the overall position. The 727th rank out of 1800 indicates that many combos use higher-end GPUs or CPUs that push frame rates beyond what this pairing achieves.

Given the measured FPS, the combo's rank is somewhat surprising—1080p frame rates above 280 FPS would typically place a system in the top quartile. However, Roblox's low system requirements mean that even mid-range hardware can achieve high frame rates, compressing the performance distribution. The 727th rank suggests that a significant number of tested combos use even more powerful components, or that the game's engine does not scale perfectly with the RTX 3070 Ti's high-end feature set. Nonetheless, the data confirms that this combo delivers smooth, high-FPS gameplay across all tested settings and resolutions.
