Roblox

Roblox with an Intel Core i5-12400 and NVIDIA GeForce RTX 4070 Ti SUPER produces extraordinarily high frame rates across all tested settings, positioning this combo in the top tier of configurations. The measured data reveals a system that is overwhelmingly GPU-bound at higher resolutions but shifts toward CPU limitations at 1080p, where frame rates exceed what most high-refresh displays can showcase.

Resolution Scaling

The transition from 1920x1080 to 3840x2160 demonstrates a predictable yet steep performance curve, with the average FPS dropping by roughly 62-63% across all settings. At 1080p Low, the combo achieves 596.7 FPS, while the same settings at 4K yield 226.7 FPS — a clear indicator that the rendering load is scaling heavily with pixel count. The gap between 1440p and 4K is particularly pronounced: High settings fall from 315.5 FPS at 2560x1440 to 179 FPS at 3840x2160, a 43% reduction that suggests the RTX 4070 Ti SUPER is being pushed toward its limits as resolution increases.

What stands out is the relatively modest drop from 1080p to 1440p compared to the 1440p to 4K step. At Low settings, 1080p produces 596.7 FPS versus 396 FPS at 1440p (a 34% decline), but 1440p to 4K shows a 43% decline (396 to 226.7 FPS). This accelerating degradation points to the GPU becoming the primary limiting factor at 4K, whereas at 1080p, the i5-12400's six cores may be holding back the GPU from reaching even higher numbers. The data implies that for competitive play at 1080p, the CPU is the bottleneck; at 4K, the GPU dominates the performance equation.

CPU Role

The Intel Core i5-12400 brings six cores and twelve threads to this pairing, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. Its benchmark scores show a balanced profile: a single-thread score of 910 in 3dmark and 2249 in Cinebench R23, alongside a multi-thread score of 15935 in the same test. This places the CPU at the 77th percentile versus all CPUs, with an average benchmark score of 19850. The nearest rival, the Intel Core i7-9700, scores 19831 (0.1% ahead), while the AMD Ryzen Threadripper PRO 5995WX sits 0.4% behind — indicating the i5-12400 is competitive with much more expensive parts in synthetic workloads.

In Roblox, the CPU's role becomes evident when examining the 1080p results. At Low settings, the combo hits 596.7 FPS, which is remarkably high but still below what the RTX 4070 Ti SUPER could theoretically produce if unconstrained. The fact that Ultra settings at 1080p still manage 384.7 FPS suggests the CPU is keeping up reasonably well, but the scaling from Low to Ultra at 1080p (a 36% drop) is steeper than at 4K (a 36% drop from Low to Ultra as well, from 226.7 to 145 FPS). This consistency across resolutions implies the CPU's 18 MB of shared L3 cache and 12 threads are sufficient for Roblox's sandbox workloads, though the game's single-threaded nature likely benefits from the 4.40 GHz boost clock.

GPU Role

The NVIDIA GeForce RTX 4070 Ti SUPER is the dominant force in this pairing, with 16 GB of GDDR6X memory on a 256-bit bus delivering 672.3 GB/s of bandwidth. Its boost clock of 2610 MHz and 8448 shading units contribute to a passmark G3D score of 31811, placing it at the 86th percentile versus all GPUs. The average benchmark score of 48704 puts it slightly ahead of the NVIDIA CMP 50HX (49071, -0.7% delta) and well ahead of the NVIDIA RTX A2000 (47915, +1.6% delta), confirming its position as a high-end part.

The GPU's impact on Roblox is unmistakable when comparing settings within each resolution. At 4K, Ultra settings produce 145 FPS versus 226.7 FPS at Low — a 56% performance penalty for maxing out visual quality. This gap narrows at 1440p (259.2 vs 396 FPS, a 53% penalty) and 1080p (384.7 vs 596.7 FPS, a 55% penalty), showing that the settings load scales relatively uniformly. The 16 GB VRAM is likely never strained by Roblox's modest texture requirements, allowing the GPU to focus on compute and rasterization. The 44.10 TFLOPS FP32 performance and 250.6 GPixel/s pixel rate provide ample headroom for the game's blocky geometry, though the data suggests even this powerful GPU cannot maintain 4K Ultra above 145 FPS.

How This Combo Ranks

Among 1800 tested combos, this i5-12400 + RTX 4070 Ti SUPER pairing ranks 218th in Roblox, placing it in the top 12% of all configurations. This ranking is slightly lower than the individual component percentiles (CPU at 77th, GPU at 86th), which suggests the combination is not perfectly optimized for this specific game. The gap between the GPU's 86th percentile and the combo's 218th out of 1800 (roughly 88th percentile) implies that the CPU is holding back the GPU in some scenarios, particularly at lower resolutions where the frame rates are exceptionally high.

The ranking becomes more meaningful when considering the game's age and simplicity. Roblox, released in 2006, is not a graphically demanding title, so the RTX 4070 Ti SUPER is overkill for most scenarios. However, the combo still achieves 145 FPS at 4K Ultra, which is excellent for a sandbox game. The data suggests that pairing a less powerful GPU with this CPU might yield similar results at 1080p, but the 4K performance would suffer significantly. The combo's rank reflects a system that is well-balanced for high-resolution gaming but leaves performance on the table at 1080p due to CPU limitations.

Settings Recommendations

The measured FPS data offers clear guidance for optimal settings. At 3840x2160, Medium settings provide 201.7 FPS, which is 27% higher than High (179 FPS) and 39% higher than Ultra (145 FPS), while only sacrificing a modest visual quality bump over Low (226.7 FPS). For 4K users, Medium is the sweet spot, delivering smooth frame rates without the dramatic performance hit of Ultra.

At 2560x1440, High settings hit 315.5 FPS, which is more than enough for any 144Hz or 240Hz display. Pushing to Ultra yields 259.2 FPS, still excellent, but the 18% performance drop from High may not justify the visual gains. For 1080p, the situation changes: even Ultra produces 384.7 FPS, so users with high-refresh monitors can max out settings without concern. Low settings at 1080p reach 596.7 FPS, which only matters for extreme competitive play where every frame counts. The data suggests that Medium at 4K, High at 1440p, and Ultra at 1080p offer the best balance of visual fidelity and performance.

Measured FPS Breakdown

At 1920x1080, the combo delivers 596.7 FPS on Low, 537.5 FPS on Medium, 478.7 FPS on High, and 384.7 FPS on Ultra. The step from Low to Medium costs 59.2 FPS (10% drop), Medium to High costs 58.8 FPS (11% drop), and High to Ultra costs 94 FPS (20% drop). The Ultra preset is notably more demanding, likely due to additional lighting and shadow effects.

At 2560x1440, results scale down proportionally: Low produces 396 FPS, Medium 361.2 FPS, High 315.5 FPS, and Ultra 259.2 FPS. The percentage drops between settings are similar to 1080p, with Ultra taking the largest hit (18% from High). At 3840x2160, the numbers compress further: Low hits 226.7 FPS, Medium 201.7 FPS, High 179 FPS, and Ultra 145 FPS. The Ultra preset at 4K is the only configuration that falls below 150 FPS, while all other combinations exceed 145 FPS. Across all resolutions and settings, the minimum recorded average is 145 FPS, which remains well above the 60 FPS standard and even exceeds most 144Hz displays' refresh rates.

FAQ

Q: Can this combo run Roblox at 4K Ultra settings?

A: Yes, it achieves 145 FPS at 3840x2160 Ultra, which is playable and smooth, though lower settings provide significantly higher frame rates (up to 226.7 FPS at Low).

Q: Is the CPU or GPU the bottleneck in this system for Roblox?

A: The data indicates the GPU is the limiting factor at 4K, where frame rates drop substantially (226.7 to 145 FPS from Low to Ultra). At 1080p, the CPU becomes more of a constraint, with Low settings maxing out at 596.7 FPS rather than exceeding 600 FPS.

Q: How does the i5-12400 compare to its nearest rival?

A: The i5-12400's average benchmark score of 19850 is nearly identical to the Intel Core i7-9700 (19831, 0.1% higher), making them effectively equivalent in synthetic workloads.

Q: What is the best settings preset for 1440p gaming?

A: High settings at 2560x1440 produce 315.5 FPS, which is ideal for high-refresh monitors. Ultra is also viable at 259.2 FPS, but the 18% performance reduction may not justify the visual upgrade.

Q: How much VRAM does the RTX 4070 Ti SUPER have, and is it enough for Roblox?

A: The GPU has 16 GB of GDDR6X memory. Roblox's modest texture sizes are unlikely to stress this capacity, even at 4K Ultra.

Q: Does the combo rank higher than its individual component percentiles suggest?

A: The combo ranks 218th out of 1800 (top 12%), which is slightly below the GPU's 86th percentile, suggesting the CPU limits performance in some scenarios, particularly at 1080p.
