Roblox

Roblox is a sandbox title that relies on a blend of CPU-driven game logic and GPU-accelerated rendering. The Intel Core i5-12400 paired with the NVIDIA GeForce RTX 4070 produces a dataset where frame rates scale predictably with resolution and settings, revealing which component becomes the limiting factor at each configuration.

CPU Role — cores, clocks, and how they relate to this game's results

The Intel Core i5-12400 brings 6 cores and 12 threads to the table, with a base clock of 2.50 GHz and a boost clock of 4.40 GHz. This Alder Lake-S architecture part, built on Intel's 10 nm process, has an 18 MB shared L3 cache. The benchmark data positions this CPU at the 77th percentile among all tested processors, with an average benchmark score of 19850. Its nearest rivals in aggregate performance are the Intel Core i7-9700 (avg score 19831, deltaPct 0.1) and the Intel Core i7-8700 (avg score 19894, deltaPct -0.2), showing that the i5-12400 sits in a tightly contested performance band.

In the context of Roblox, the CPU's single-threaded throughput matters for game simulation and script execution. The 3DMark single-thread score of 910 and Cinebench R23 single-core score of 2249 indicate strong per-core performance. The multi-threaded results, such as Cinebench R23 multi-core at 15935, provide ample headroom for background tasks. However, the measured FPS data suggests that at lower resolutions and settings, the CPU is not the bottleneck. At 1920x1080 with Low settings, the combo achieves 503.2 FPS, which is substantially higher than the 4K Ultra result of 123.9 FPS. This scaling pattern implies that Roblox's rendering workload, not CPU physics, drives the frame rate differences across configurations.

The 3DMark 2-thread score of 1692 and 4-thread score of 3012 show that the processor scales well with additional threads, but Roblox's typical workload does not appear to demand the full 12-thread capacity, as evidenced by the consistent frame rates across settings at a given resolution.

GPU Role — VRAM, clocks, and how they relate to this game's results

The NVIDIA GeForce RTX 4070 is built on the Ada Lovelace architecture with a 5 nm process from TSMC. It features 12 GB of GDDR6X memory on a 192-bit bus, delivering 504.2 GB/s of bandwidth. The GPU's boost clock is 2475 MHz, with a base clock of 1920 MHz. The 5888 shading units and 46 RT cores provide substantial compute capacity, reflected in a 29.15 TFLOPS FP32 rating. The GPU sits at the 81st percentile among all tested graphics cards, with an average benchmark score of 37283.

The VRAM capacity is more than sufficient for Roblox, which does not require large texture pools. The measured FPS data shows the GPU's performance scaling with resolution: at 3840x2160 High settings, the average FPS is 155.9, while at 2560x1440 High it jumps to 270.6, and at 1920x1080 High it reaches 402.2. This pattern indicates that the GPU is the primary driver of frame rate differences across resolutions, as the CPU is capable of feeding frames faster than the GPU can render them at higher pixel counts.

The nearest rivals for this GPU in aggregate benchmarks include the AMD Radeon RX Vega 56 (avg score 37507, deltaPct -0.6) and the NVIDIA GeForce MX570 A (avg score 38008, deltaPct -1.9), demonstrating that the RTX 4070's average score of 37283 is competitive with those parts, though the actual in-game performance for Roblox is far above what those older architectures would likely deliver.

How This Combo Ranks

The combination of the Intel Core i5-12400 and NVIDIA GeForce RTX 4070 ranks 460th out of 1800 tested combos in Roblox, placing it in the upper quartile of all configurations. This rank reflects the balance between a mid-range CPU and a high-end GPU, where the GPU's rendering capabilities are the primary contributor to the game's frame rates. The CPU's 77th percentile standing and the GPU's 81st percentile standing both support a top-tier ranking, though the exact position suggests that some combinations with stronger CPUs or GPUs achieve higher scores in this specific title.

The data indicates that this combo is not at the absolute top of the leaderboard, but it sits comfortably above the median. The rank of 460 out of 1800 means that roughly 74% of tested combos perform worse in Roblox, which aligns with the high frame rates measured across all resolutions. The gap between this combo and the top performers likely stems from CPU-bound scenarios at lower resolutions, where faster processors could push even higher frame rates.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance across three resolutions and four settings levels. At 1920x1080, the combo delivers 503.2 FPS on Low, 457.0 FPS on Medium, 402.2 FPS on High, and 324.5 FPS on Ultra. These numbers show a steady decline as settings increase, with the drop from Low to Ultra being 178.7 FPS. At 2560x1440, the results are 335.5 FPS (Low), 307.2 FPS (Medium), 270.6 FPS (High), and 218.1 FPS (Ultra). The difference between Low and Ultra here is 117.4 FPS, a smaller absolute gap than at 1080p, indicating that the GPU is becoming more of a limiting factor as pixel count rises.

At 3840x2160, the frame rates drop further: 190.2 FPS on Low, 171.0 FPS on Medium, 155.9 FPS on High, and 123.9 FPS on Ultra. The gap between Low and Ultra is 66.3 FPS, the smallest absolute difference across the three resolutions. This trend shows that at 4K, the GPU's rendering workload dominates, and the settings-based performance scaling compresses. The data also reveals that even at 4K Ultra, the combo maintains an average above 120 FPS, which is a strong result for a sandbox game with potentially complex scenes.

Resolution scaling is consistent: moving from 1080p to 1440p reduces frame rates by roughly 33-36% across settings, while moving from 1440p to 4K reduces them by another 43-45%. This linear scaling pattern suggests that the GPU's compute and memory bandwidth are the main constraints at higher resolutions.

Settings Recommendations

Based on the measured FPS rows, the optimal settings depend on the target display resolution and desired frame rate. For 1920x1080, all settings produce frame rates well above 300 FPS, so the choice comes down to visual quality versus refresh rate headroom. Ultra settings at 324.5 FPS still exceed the refresh rate of most high-end monitors (typically 240 Hz or 360 Hz), making Ultra a viable option for 1080p gaming without sacrificing smoothness.

At 2560x1440, Ultra settings deliver 218.1 FPS, which comfortably exceeds 144 Hz and even 165 Hz refresh rates. High settings at 270.6 FPS provide additional headroom for competitive play, while Medium at 307.2 FPS offers a balanced trade-off. Low settings at 335.5 FPS are only marginally faster than Medium, so the latter is likely the better choice for most users at this resolution.

For 3840x2160, Ultra settings produce 123.9 FPS, which is above 120 Hz but below 144 Hz. High settings at 155.9 FPS exceed 144 Hz, making this the recommended preset for 4K displays with high refresh rates. Medium at 171.0 FPS provides even more headroom, while Low at 190.2 FPS maximizes frame rate for competitive scenarios. The data suggests that High settings at 4K offer the best balance between visual fidelity and performance, as the difference between High and Ultra is 32 FPS, which is significant for maintaining a smooth experience on 144 Hz monitors.

Across all resolutions, the combo consistently delivers playable frame rates even at the highest settings, so the recommendation is to prioritize refresh rate targets. For 1080p and 1440p, Ultra settings are generally sufficient. For 4K, High settings are the sweet spot, as the drop to Ultra brings the frame rate below 144 FPS, which may be noticeable on high-refresh displays.
