Roblox

The Intel Core i5-11400F paired with the NVIDIA GeForce GTX 1660 SUPER delivers a robust Roblox experience, with average frame rates that comfortably exceed display refresh rate targets across most configurations. The measured data reveals a system that scales predictably with resolution and settings, though the bottlenecks shift noticeably depending on the workload. This analysis breaks down the measured FPS, placing the results in the context of the component specifications and the broader benchmark database.

Resolution Scaling

The FPS drop from 1080p to 4K is substantial, highlighting the increasing load on the graphics card as pixel count rises. At 1080p with Low settings, the combo produces 234.9 FPS, but this falls to 88.2 FPS at 4K—a drop that indicates the GPU is becoming the primary limiting factor at higher resolutions. The scaling curve is not linear; moving from 1080p to 1440p at Low settings reduces performance from 234.9 to 159.2 FPS, while the jump from 1440p to 4K at the same settings yields a further decrease to 88.2 FPS. This suggests that while the GTX 1660 SUPER handles 1080p with significant headroom, the 4K Ultra settings push the card to its limits, where the 60.3 FPS average is barely above the minimum threshold for smooth gameplay.

Interestingly, the gap between Low and Ultra settings widens as resolution increases. At 1080p, the difference between Low (234.9 FPS) and Ultra (152.8 FPS) is 82.1 FPS, but at 4K, the same settings gap shrinks to 27.9 FPS (88.2 vs 60.3). This compression suggests that at 4K, the GPU is so saturated that the settings changes have a relatively smaller impact on the final frame rate. The data implies that for players targeting 4K, the limiting component is unequivocally the GPU, whereas at 1080p, the CPU’s role becomes more relevant.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. Its benchmark results show a strong single-thread score of 868 in 3dmark_single_thread and 2029 in cinebench_r23_singlecore, which is critical for Roblox’s often single-threaded game logic. The CPU’s multi-threaded capabilities are also respectable, with a cinebench_r23_multicore score of 14372, but the game’s engine likely relies more on the per-core performance.

The data indicates that at 1080p Low settings, the system reaches 234.9 FPS, which is likely near the upper bound of what the CPU can feed to the GPU. The 3dmark_2_threads score of 1691 suggests that the CPU’s dual-thread performance is solid, but the gap between 1080p Low (234.9 FPS) and 1440p Low (159.2 FPS) is disproportionately large compared to the pixel count increase. This implies that at 1080p, the CPU is keeping up, but the GPU is already working harder as resolution increases. The CPU’s 12 MB of shared L3 cache and 51.2 GB/s memory bandwidth provide sufficient data throughput, but the processor’s 65 W TDP and 14 nm process node indicate it is not a top-tier part. In the benchmark database, the i5-11400F ranks in the 75th percentile of all CPUs, with an average benchmark score of 17181, placing it close to rivals like the AMD Ryzen 7 5700U and Intel Core i7-1260P.

GPU Role

The NVIDIA GeForce GTX 1660 SUPER is the clear workhorse for this combo in Roblox, especially at higher resolutions. With 6 GB of GDDR6 memory on a 192-bit bus, the card offers 336.0 GB/s of bandwidth, which is ample for the game’s textures. The GPU’s base clock of 1530 MHz and boost clock of 1785 MHz, combined with 1408 shading units, deliver a measured 5.027 TFLOPS of FP32 compute. This power is evident in the 4K High settings result of 69.5 FPS, which is playable but not silky smooth.

The GPU’s benchmark percentile is 55th among all GPUs, with an average score of 14286. Its nearest rivals in the database include the AMD Radeon RX Vega 11 and Intel Iris Xe MAX Graphics, with delta percentages of -0.2% and -0.2%, respectively. This places the GTX 1660 SUPER in a mid-range tier. The VRAM capacity of 6 GB is sufficient for Roblox at 1080p and 1440p, but at 4K Ultra, the 60.3 FPS average suggests the card is nearing its memory and compute limits. The GPU’s 48 ROPs and 88 TMUs are adequate, but the 125 W TDP indicates it is not a high-end power consumer. The performance gap between 1440p Ultra (102.4 FPS) and 4K Ultra (60.3 FPS) is a steep 42.1 FPS drop, underscoring how the GPU’s fill rate and memory bandwidth become strained at 4K.

How This Combo Ranks

In the global database of tested combinations, this specific pairing of the i5-11400F and GTX 1660 SUPER ranks 1605 out of 1800 combos for Roblox. This places it in the 11th percentile of all tested systems, which might seem low given the frame rates, but it reflects the vast number of higher-end configurations in the database. The rank suggests that while this combo is far from the top, it is not at the bottom either, and its measured FPS data shows it can handle the game smoothly at most settings.

The combo’s performance is more impressive when considering the CPU and GPU individually. The CPU’s 75th percentile ranking and the GPU’s 55th percentile ranking suggest a balanced pairing, but the GPU is the weaker link. In the context of Roblox, which is not a graphically demanding title, this combo still manages to deliver 152.8 FPS at 1080p Ultra, which is well above the 60 FPS target. The rank of 1605 out of 1800 indicates that many systems with newer or higher-tier components outperform it, but the data shows that for the price point of these components, the performance is respectable.

Settings Recommendations

Based on the measured FPS rows, the best experience balances visual quality with frame rate stability. At 1080p, the Ultra preset yields 152.8 FPS, which is still exceptionally high, so players with a 144 Hz monitor can enjoy maximum settings without compromise. For those with a 240 Hz display, the Medium preset at 213 FPS is the sweet spot, as it offers a significant boost over Ultra while maintaining high visual fidelity. At 1440p, the High preset delivers 129.7 FPS, which is ideal for a 120 Hz or 144 Hz monitor, while the Medium preset at 142.8 FPS is also viable. The Ultra preset at 1440p drops to 102.4 FPS, which is still playable but less smooth.

At 4K, the settings recommendations become more conservative. The High preset at 69.5 FPS is the best choice for a 60 Hz display, as it provides a stable experience without the performance hit of Ultra (60.3 FPS) or the visual downgrade of Medium (78.5 FPS). The Low preset at 88.2 FPS is an option for players prioritizing frame rate over visuals, but the Medium preset at 78.5 FPS is arguably the best balance for 4K. In summary, the data suggests that 1080p and 1440p players should stick to Ultra or High, while 4K users should prefer High or Medium.

Measured FPS Breakdown

At 1920x1080, the average FPS ranges from 234.9 on Low to 152.8 on Ultra. The Medium preset hits 213 FPS, and High settles at 193.2 FPS. The spread of 82.1 FPS between Low and Ultra shows the GPU has ample headroom at this resolution.

Moving to 2560x1440, the averages are 159.2 FPS on Low, 142.8 FPS on Medium, 129.7 FPS on High, and 102.4 FPS on Ultra. The drop from 1080p to 1440p is most pronounced on Low (a 75.7 FPS decrease), while the Ultra preset only loses 50.4 FPS.

At 3840x2160, the averages are 88.2 FPS on Low, 78.5 FPS on Medium, 69.5 FPS on High, and 60.3 FPS on Ultra. The difference between Low and Ultra is 27.9 FPS, which is the smallest gap across all resolutions. This indicates that at 4K, the GPU is the limiting factor regardless of settings, and the CPU has less influence on the final frame rate.
