Roblox

Roblox, a sandbox title from 2006, exhibits remarkably high frame rates on the Intel Core i5-11400F and AMD Radeon RX 7600 combination. The measured data reveals a system that is heavily optimized for this specific game, with performance scaling that suggests the graphics card is the primary bottleneck at higher resolutions, while the CPU remains capable of pushing hundreds of frames per second at lower settings.

Resolution Scaling

The performance drop from 1080p to 4K is substantial but not linear, indicating a shift in the limiting component. At 1920x1080 with Low settings, the system produces 310.8 FPS on average. Moving to 2560x1440 at Low settings, the average drops to 208.7 FPS, a 32.9% decrease. Scaling further to 3840x2160 at Low settings yields 116.6 FPS, another 44.1% drop from the 1440p figure. This dramatic reduction as resolution increases points directly to the GPU becoming the constraining factor.

The pattern is consistent across all settings presets. At High settings, frame rates fall from 250.6 at 1080p to 167.1 at 1440p, then to 96.1 at 4K. The Ultra preset shows the same trajectory: 202.2 FPS at 1080p, 134.2 FPS at 1440p, and 78.6 FPS at 4K. The gap between Low and Ultra settings widens as resolution increases, with the difference being 108.6 FPS at 1080p but only 38.0 FPS at 4K. This compression at higher resolutions is classic GPU-bound behavior, where pixel throughput becomes the dominant cost.

At 1080p, the frame rates exceed 200 FPS even on Ultra, which suggests the CPU is not fully saturated. The Core i5-11400F, with its 6 cores and 12 threads, provides ample headroom for Roblox's engine at lower resolutions. The data implies that at 4K, the RX 7600's 8 GB of GDDR6 memory and 128-bit bus are working near their limits, while the CPU's 12 MB of shared L3 cache and 51.2 GB/s memory bandwidth are sufficient for the game's logic and physics.

Settings Recommendations

The measured data shows that the Medium preset offers the best balance between visual quality and performance. At 1920x1080, Medium produces 279.7 FPS, which is 29.1 FPS higher than High but 31.1 FPS lower than Low. This positions Medium as the sweet spot for competitive play, retaining most of the visual fidelity while maintaining frame rates well above 240 Hz.

At 2560x1440, Medium delivers 185.6 FPS, comfortably exceeding 144 Hz refresh rates. The jump from Medium to High at this resolution costs 18.5 FPS, resulting in 167.1 FPS. For users with 144 Hz monitors, Medium is the recommended choice, as it provides a substantial margin above the refresh rate threshold. High settings remain viable but offer diminishing returns in terms of visual improvements relative to the FPS loss.

At 3840x2160, the recommendation shifts to High settings, which deliver 96.1 FPS. Ultra drops to 78.6 FPS, while Medium only reaches 107.8 FPS. The difference between High and Ultra is 17.5 FPS, but High provides a significant visual upgrade over Medium at a cost of just 11.7 FPS. For 4K displays, High strikes the optimal balance, keeping frame rates above 90 FPS while leveraging the RX 7600's shading units and texture mapping units.

The Low preset is only advisable for competitive play at 1080p, where the 310.8 FPS average can fully utilize 300 Hz monitors. At higher resolutions, Low's performance advantage narrows enough that its visual compromises become less worthwhile.

How This Combo Ranks

The Intel Core i5-11400F paired with the AMD Radeon RX 7600 ranks 1214th out of 1800 tested combinations in Roblox. This places the combo in the 32.6th percentile of all tested systems, which is lower than the individual component percentiles might suggest. The CPU sits in the 75th percentile among all CPUs, while the GPU is in the 63rd percentile among all GPUs. The disparity between component rankings and the combined ranking indicates that Roblox's engine does not fully utilize the hardware's theoretical potential.

The ranking is likely influenced by the game's age and optimization patterns. Roblox, released in 2006, may not scale perfectly with modern hardware architectures. The combo's position suggests that while each component is individually capable, the combination faces diminishing returns in this specific title. The 8 GB of VRAM on the RX 7600 is ample for Roblox's asset sizes, so the GPU memory is not a limiting factor in the ranking.

In comparison to other combos, the 1214th rank out of 1800 means 586 tested combinations performed worse. This is a mid-pack result, reflecting the fact that Roblox is not particularly demanding compared to other modern games. The high absolute frame rates (above 200 FPS at 1080p Medium) confirm that the hardware is more than adequate, even if its relative ranking is modest due to the competitive field.

GPU Role

The AMD Radeon RX 7600 plays a decisive role in determining frame rates at higher resolutions. Its 8 GB of GDDR6 memory on a 128-bit bus provides 288.0 GB/s of bandwidth, which becomes increasingly important as pixel count rises. The GPU's base clock of 1720 MHz and boost clock of 2655 MHz, with a game clock of 2250 MHz, allow it to maintain high throughput in sustained workloads.

The memory operates at 2250 MHz with 18 Gbps effective speed, which is adequate for Roblox's texture streaming and draw calls. The 2048 shading units and 64 ROPs handle the game's geometry and pixel processing efficiently. At 4K Ultra, the 78.6 FPS result indicates the GPU is nearing its pixel fill rate limits, with the 169.9 GPixel/s pixel rate being the constraining factor.

The GPU's RDNA 3.0 architecture supports DirectX 12 Ultimate, which Roblox can leverage for modern rendering features. However, the game's sandbox nature means many scenes are simple block-based environments, reducing the demand on the GPU's compute capabilities. The 21.75 TFLOPS of FP32 performance is more than sufficient for the game's shader complexity, and the 339.8 GTexel/s texture rate ensures that texture-heavy scenes do not become bottlenecks.

The RX 7600's 63rd percentile ranking among all GPUs, with an average benchmark score of 20258, places it above the RX 460 (0.8% lower) but below the RTX 3070 Mobile (1.3% higher). This positioning aligns with its in-game performance, which shows strong results at 1080p and 1440p, with 4K being the only resolution where frame rates drop below 100 FPS on demanding presets.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest frame rates. Low settings produce 310.8 FPS, Medium produces 279.7 FPS, High produces 250.6 FPS, and Ultra produces 202.2 FPS. The spread from Low to Ultra is 108.6 FPS, with each preset step costing approximately 25-30 FPS. This resolution is clearly CPU-bound, as the frame rates exceed what most displays can show.

At 2560x1440, performance remains strong but begins to show GPU influence. Low settings average 208.7 FPS, Medium 185.6 FPS, High 167.1 FPS, and Ultra 134.2 FPS. The step from High to Ultra costs 32.9 FPS, the largest single drop at this resolution. The difference between Low and Ultra is 74.5 FPS, showing that settings choice has a significant impact.

At 3840x2160, the GPU becomes the clear bottleneck. Low settings average 116.6 FPS, Medium 107.8 FPS, High 96.1 FPS, and Ultra 78.6 FPS. The scaling from Low to Ultra shows a 38.0 FPS total difference, with each preset step costing roughly 9-13 FPS. This compressed range indicates that the GPU is near its saturation point, as even the lowest settings cannot fully alleviate the pixel throughput demands.

The data reveals a consistent pattern: at every resolution, the difference between Medium and High is smaller than the difference between High and Ultra. For example, at 1440p, Medium to High costs 18.5 FPS, while High to Ultra costs 32.9 FPS. This suggests that Ultra settings introduce disproportionately expensive effects that strain the GPU without proportional visual gains.
