Roblox

Roblox is a peculiar case for hardware analysis because its simple visuals can still produce massive frame rate swings depending on the settings preset and resolution. For the Intel Core i5-11400F paired with the AMD Radeon RX 6600, the measured data shows a combo that is more than capable of delivering high refresh rates at 1080p, but the scaling pattern reveals where the bottlenecks shift as you move up in resolution. The benchmark results indicate that this pairing is firmly in the upper tier of tested configurations, ranking 1445 out of 1800 combos, which places it in the 80th percentile of all tested systems.

Resolution Scaling

The frame rate drop from 1080p to 4K is steep but consistent with what you would expect from a mid-range GPU. At Ultra settings, the average FPS falls from 182.5 at 1920x1080 to 121.2 at 2560x1440, then down to 67.5 at 3840x2160. That represents a 33% loss from 1080p to 1440p, and then a further 44% loss when jumping to 4K. The pattern is similar for High settings, where the drop is from 226.5 to 149.8 to 87 across the three resolutions. This tells us that the RX 6600 is the primary limiter at 4K, as the frame rates drop below the 100 FPS mark that many gamers consider the floor for smooth gameplay.

The Low preset shows a different story. At 1080p Low, the combo hits 284.1 FPS, which is close to what a 144Hz monitor can display. Dropping to 1440p Low still yields 191.2 FPS, and even at 4K Low, the system manages 103.5 FPS. This scaling suggests that when the GPU load is lightened, the i5-11400F has enough headroom to keep feeding the graphics card, but the RX 6600 still hits its ceiling at 4K. The difference between 1080p Low and 1440p Low is 92.9 FPS, while the difference between 1440p Low and 4K Low is 87.7 FPS — a nearly linear drop that indicates the GPU is working proportionally harder at each step up in resolution.

The Medium preset follows the expected curve, with 254.1 FPS at 1080p, 172.1 at 1440p, and 98.4 at 4K. The Ultra preset is the most demanding, and the 4K result of 67.5 FPS is the only measured point in the entire dataset that falls below the 70 FPS threshold. This makes it clear that 4K Ultra is not a realistic target for this combo, but 1440p Ultra at 121.2 FPS is perfectly playable on a high refresh rate display.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor based on the Rocket Lake architecture, built on Intel's 14 nm process. Its base clock of 2.60 GHz and boost clock of 4.40 GHz are modest by today's standards, but the benchmark data shows it handles Roblox's threading model without issue. The Cinebench R23 multi-core score of 14372 and single-core score of 2029 indicate that the CPU is not a bottleneck in this game, especially when you consider that Roblox is not a heavily threaded title.

The processor's 12 MB of shared L3 cache and dual-channel DDR4 memory support with 51.2 GB/s of bandwidth are more than sufficient for the game's data requirements. The Passmark single-thread score of 2981 is solid, and the 3DMark single-thread score of 868 suggests that the per-core performance is adequate for Roblox's physics and scripting workloads. The CPU ranks in the 75th percentile of all processors, with an average benchmark score of 17181, putting it directly between the AMD Ryzen 7 5700U and the Intel Core i7-1260P in the nearest rivals list.

Looking at the FPS data, the CPU's influence is most visible at 1080p Low, where the 284.1 FPS result is likely approaching the engine's frame rate ceiling. At 1080p Ultra, the frame rate drops to 182.5, which is a 36% reduction from Low. This gap is larger than the difference between Medium and Low, which suggests that the Ultra preset adds CPU-intensive effects that the i5-11400F can handle but that do cost performance. The fact that 1080p Medium hits 254.1 FPS while 1080p High hits 226.5 shows that the CPU is not the limiting factor here — the GPU is doing most of the heavy lifting at these settings.

Settings Recommendations

For 1080p users, the Medium preset offers the best balance of visual quality and frame rate. The measured 254.1 FPS at Medium is 12% higher than High's 226.5 FPS, and the visual difference between these presets in a blocky sandbox game is often negligible. If you have a 144Hz monitor, High is still more than sufficient at 226.5 FPS, but Medium gives you more headroom for demanding user-created worlds that may have additional physics or script load.

At 1440p, the Ultra preset delivers 121.2 FPS, which is above the 120 FPS threshold that many gamers target. However, if you prefer a higher frame rate buffer, the High preset at 149.8 FPS is the safer choice, as it provides a 24% performance increase over Ultra while retaining most of the visual enhancements. The Medium preset at 172.1 FPS is the best option for those who want to ensure their frame rate never dips below 144 FPS, as it has a substantial margin over the target.

For 4K displays, the data strongly recommends the Low preset, which achieves 103.5 FPS. The Medium preset drops to 98.4 FPS, which is still playable, but the High preset at 87 FPS and Ultra at 67.5 FPS are too close to the 60 FPS minimum for comfort. The Low preset at 4K is the only way to maintain a triple-digit frame rate on this combo, and given the game's art style, the visual sacrifice is minimal.

How This Combo Ranks

The combo rank of 1445 out of 1800 tested configurations places this pairing in the top 20% of all systems. This is a strong showing for a mid-range CPU and GPU combination, and it reflects the fact that Roblox is not particularly demanding on either component. The rank is likely higher than what you would see in more graphically intensive titles, where the RX 6600 would fall further behind higher-end GPUs.

The CPU's percentile rank of 75 and the GPU's percentile rank of 69 both contribute to this solid overall position. The i5-11400F's average benchmark score of 17181 is nearly identical to the AMD Ryzen 7 5700U's 17189, with a delta of 0%, meaning these two processors perform at essentially the same level in synthetic tests. The GPU's average score of 25235 puts it on par with the AMD Radeon 890M (25246) and slightly ahead of the AMD Radeon RX 580 2048SP (25287, delta -0.2%). This means the pairing is well-balanced, with neither component significantly outclassing the other.

GPU Role

The AMD Radeon RX 6600 is built on the RDNA 2.0 architecture with a 7 nm process from TSMC, featuring 1792 shading units, 112 texture mapping units, and 64 raster operation units. The GPU has 8 GB of GDDR6 memory on a 128-bit bus, providing 224.0 GB/s of bandwidth. The boost clock of 2491 MHz and game clock of 2044 MHz are respectable for this class of card, and the 8.928 TFLOPS of FP32 performance is more than enough for Roblox's simple shaders.

The Passmark G3D score of 15096 and the 3DMark Steel Nomad DX12 score of 1492 confirm that this GPU performs in the mid-range tier. The GPU compute score of 6554 is modest, but Roblox does not rely heavily on compute shaders. The 28 ray tracing cores are present but largely unused in this game, which means the RX 6600 can dedicate its full rasterization throughput to rendering the game's blocky geometry.

The VRAM capacity of 8 GB is not a concern at any of the tested resolutions, as Roblox's textures are generally small and low-resolution. The memory bandwidth of 224.0 GB/s is sufficient for 4K rendering, as evidenced by the 4K Low result of 103.5 FPS. The GPU's role becomes more pronounced at higher settings, where the difference between Low and Ultra at 4K is 36 FPS (103.5 vs 67.5), showing that the card's shading units and texture units are the limiting factor when the preset increases visual complexity.

Measured FPS Breakdown

At 1920x1080, the measured average FPS values are 284.1 for Low, 254.1 for Medium, 226.5 for High, and 182.5 for Ultra. The gap between Low and Ultra is 101.6 FPS, which represents a 36% performance penalty for maxing out the settings. The step between Medium and High is 27.6 FPS, while the step between High and Ultra is 44 FPS, indicating that the Ultra preset is disproportionately more demanding than High.

At 2560x1440, the results are 191.2 FPS for Low, 172.1 for Medium, 149.8 for High, and 121.2 for Ultra. The difference between Low and Ultra is 70 FPS, which is a 37% penalty. The scaling from 1080p to 1440p at each preset is roughly 33% across the board, showing consistent GPU scaling without any sudden bottleneck shifts.

At 3840x2160, the results are 103.5 FPS for Low, 98.4 for Medium, 87 for High, and 67.5 for Ultra. The difference between Low and Ultra is 36 FPS, which is a 35% penalty. The drop from 1440p to 4K at each preset is approximately 44%, which is larger than the 1080p to 1440p drop, confirming that the RX 6600's memory bandwidth and pixel fill rate become the limiting factors at 4K. The data shows that this combo is best suited for 1080p and 1440p gaming, with 4K being viable only at Low or Medium settings.
