Roblox

The Intel Core i5-12400F is a 6-core, 12-thread desktop processor built on the Alder Lake architecture and the Intel Socket 1700 platform. It operates with a base clock of 2.50 GHz and a boost clock of 4.40 GHz, drawing a 65 W TDP. The CPU’s cache hierarchy includes 80 KB of L1 per core, 1.25 MB of L2 per core, and a shared 18 MB L3 cache. In synthetic benchmarks, it scores 16,518 in Cinebench R23 multi-core and 2,332 in single-core, while its PassMark multithread score is 19,433. Its average benchmark score of 19,221 places it at the 77th percentile of all CPUs, with its nearest rivals being the Intel Core i7-8700K (average score 19,210, a delta of 0.1% ahead) and the AMD Ryzen 5 7533HS (average score 19,364, a delta of -0.7% behind).

In the context of Roblox, a sandbox title that often relies heavily on single-thread performance for game logic and physics, the i5-12400F’s strong single-core results (a 3DMark single-thread score of 909) are particularly relevant. The game’s performance at lower resolutions, where the CPU is more likely to be the limiting factor, shows the processor’s ability to drive high frame rates. The benchmark results indicate that the i5-12400F provides a solid foundation for this game, with its 12 threads ensuring that background tasks and the game’s multi-threaded aspects do not create bottlenecks. The data shows that the processor is capable of exceeding 600 FPS at 1080p Low settings, which heavily implicates the CPU’s headroom in this specific workload.

GPU Role

The NVIDIA GeForce RTX 5070 Ti is the graphics powerhouse in this combination, featuring 16 GB of GDDR7 memory on a 256-bit bus delivering 896.0 GB/s of bandwidth. It is built on the Blackwell 2.0 architecture with a base clock of 2295 MHz and a boost clock of 2452 MHz. The GPU’s memory operates at 1750 MHz, translating to 28 Gbps effective. With 8,960 shading units, 280 TMUs, and 96 ROPs, the card is a massive compute resource, offering 43.94 TFLOPS of FP32 performance.

The RTX 5070 Ti’s benchmark scores are equally impressive, with a PassMark G3D score of 32,974 and a Geekbench OpenCL score of 231,226. Its average benchmark score of 52,086 places it at the 87th percentile of all GPUs, sitting directly alongside the NVIDIA GeForce RTX 4080, which has an average score of 52,085 (a 0% delta). This indicates that the GPU is a top-tier performer. In Roblox, the GPU’s role becomes more pronounced as resolution and settings increase. While the game is not typically a graphical showcase, the RTX 5070 Ti’s sheer power ensures that even at 4K Ultra settings, the frame rate remains exceptionally high. The data shows that the GPU is not the limiting factor at 1080p, but it carries more weight at 4K where the pixel count demands more from the shading units and memory bandwidth.

Resolution Scaling

The measured FPS data shows a clear scaling pattern across resolutions, with the most significant drops occurring when moving from 1440p to 4K. At 1080p High settings, the combo achieves 496.2 FPS. This drops to 333.1 FPS at 1440p High, a decrease of 163.1 FPS, and then falls further to 189.2 FPS at 4K High. This steep decline from 1440p to 4K (a 143.9 FPS drop) indicates that the workload is transitioning from a CPU-bound scenario to a more GPU-bound one.

The scaling pattern is consistent across all settings. At Low settings, the frame rate goes from 613.8 FPS at 1080p to 413.5 FPS at 1440p, then down to 232.5 FPS at 4K. The fact that the 1080p to 1440p drop (200.3 FPS) is larger than the 1440p to 4K drop (181 FPS) at Low settings suggests that the CPU is still heavily involved even at 1440p. However, at Ultra settings, the pattern shifts: 402.7 FPS at 1080p, 271.1 FPS at 1440p, and 150.7 FPS at 4K. The percentage drop from 1080p to 4K at Ultra settings is roughly 62.6%, whereas at Low settings it is 62.1%, showing that the GPU is becoming the primary constraint at higher resolutions and settings. The data clearly shows that this combo has enough power to push Roblox to extreme frame rates, but the limiting component shifts from the CPU at 1080p to the GPU as resolution climbs.

How This Combo Ranks

In the grand database of tested combinations for Roblox, this pairing of the Intel Core i5-12400F and NVIDIA GeForce RTX 5070 Ti holds a rank of 158 out of 1,800 combos. This places it in the top 8.8% of all tested systems, which is a strong showing. The rank reflects the balanced nature of the pairing, where neither component is severely bottlenecking the other in this particular title.

Given that the GPU sits at the 87th percentile and the CPU at the 77th percentile, the overall combo rank of 158 suggests that the system is performing near the top of the charts. The fact that the GPU’s nearest rival is the RTX 4080 with a 0% delta in average score reinforces that the graphics card is a high-end part. Similarly, the CPU’s close performance to the Core i7-8700K (a 0.1% delta) shows that the processor is no slouch. The data indicates that this combo is well-equipped for Roblox, and the high rank is a direct result of the CPU’s strong single-thread performance and the GPU’s massive compute throughput. The rank of 158 out of 1,800 confirms the fact that this system will not struggle with frame rates in this game, regardless of the resolution or settings chosen.

Measured FPS Breakdown

The measured FPS data provides a detailed look at how this combo performs across three resolutions and four settings presets. At 1920x1080, the frame rates are exceptionally high, with the Low preset hitting 613.8 FPS. The Medium preset yields 560.5 FPS, High yields 496.2 FPS, and the Ultra preset drops to 402.7 FPS. The spread from Low to Ultra at 1080p is 211.1 FPS, showing that the settings have a significant impact but that even the most demanding preset remains well above 400 FPS.

Moving to 2560x1440, the frame rates remain very high but show a clear step down. The Low preset delivers 413.5 FPS, while Medium achieves 371.3 FPS. High settings still produce 333.1 FPS, and Ultra falls to 271.1 FPS. The difference between Low and Ultra at this resolution is 142.4 FPS, a smaller spread than at 1080p, indicating that the GPU is starting to take on more of the load. At 4K (3840x2160), the numbers become more moderate but are still impressive for a game like Roblox. The Low preset achieves 232.5 FPS, Medium drops to 209.1 FPS, High yields 189.2 FPS, and Ultra bottoms out at 150.7 FPS. The spread between Low and Ultra at 4K is 81.8 FPS.

The data shows a consistent pattern: the RTX 5070 Ti has enough power to keep frame rates high even at 4K, but the CPU’s influence is most apparent at 1080p where the frame rates exceed 600 FPS. The benchmark results indicate that users playing at 1080p will be heavily CPU-limited, while those at 4K will still have a vastly enjoyable experience with no risk of dropping below the 150 FPS mark even at Ultra settings. The progression from 613.8 FPS at 1080p Low to 150.7 FPS at 4K Ultra represents a 75.4% reduction, but the absolute numbers remain far beyond what most displays can even refresh.
