GPU Role

The NVIDIA GeForce GTX 1660 SUPER is built on the Turing architecture with a TU116 chip manufactured on a 12 nm process. It features 1408 shading units, 88 texture mapping units, and 48 raster output units. The card operates at a base clock of 1530 MHz and a boost clock of 1785 MHz, with memory running at 1750 MHz or 14 Gbps effective. This configuration provides 6 GB of GDDR6 memory on a 192-bit bus, yielding a memory bandwidth of 336.0 GB/s.

In the context of Roblox, the GPU's role becomes more pronounced as resolution and settings increase. The data shows a clear correlation between GPU load and frame rates: at 1080p Low, the system averages 234.4 FPS, but at 4K Ultra, it drops to 55.6 FPS. This indicates that the GTX 1660 SUPER's compute capabilities, rated at 5.027 TFLOPS FP32, are sufficient for the game's relatively simple geometry at lower resolutions but become the primary constraint at higher pixel counts. The pixel rate of 85.68 GPixel/s and texture rate of 157.1 GTexel/s directly influence how quickly the card can fill frames, which is critical for maintaining smooth gameplay in a sandbox title where draw distances and object counts can vary widely.

The 6 GB VRAM capacity is ample for Roblox's texture requirements, even at Ultra settings, as the game does not typically demand large texture caches. However, the transition from 1440p to 4K shows a steep performance penalty: the High preset drops from 129.9 FPS to 73 FPS, a reduction of roughly 44%. This suggests that the GPU's memory bandwidth of 336.0 GB/s becomes a limiting factor when pushing 4K resolutions, as the card must move more pixel data per frame. The benchmark results indicate that the GTX 1660 SUPER is most comfortable at 1080p and 1440p, where it can maintain frame rates well above 100 FPS even on higher presets.

Resolution Scaling

The measured FPS data reveals a consistent pattern of performance scaling across the three tested resolutions: 1920x1080, 2560x1440, and 3840x2160. At 1080p, the average frame rates range from 152.2 FPS on Ultra to 234.4 FPS on Low, showing that the system has substantial headroom for competitive or high-refresh-rate play. Moving to 1440p, the averages drop to a range of 105.6 FPS on Ultra to 159.6 FPS on Low, with the High preset delivering 129.9 FPS. This represents a reduction of approximately 28-32% across settings when moving from 1080p to 1440p, which aligns with the increase in pixel count from 2.07 million to 3.69 million.

The jump from 1440p to 4K produces a more dramatic decline, with the High preset falling from 129.9 FPS to 73 FPS, a 44% reduction. The Low preset at 4K averages 89.2 FPS, while Medium hits 82.1 FPS and Ultra drops to 55.6 FPS. This scaling behavior indicates that the system transitions from a CPU-bound state at 1080p to a GPU-bound state at 4K. At 1080p, the i5-10400F's six cores and 12 threads can easily feed the GPU, resulting in frame rates that are likely limited by the game engine's draw call throughput. As resolution increases, the GTX 1660 SUPER's fill rate and memory bandwidth become the dominant factors, causing the frame rate to scale more steeply with resolution.

The data suggests that the sweet spot for this combo is 1440p, where the performance drop from 1080p is moderate but still allows for high refresh rates on most settings. The 4K results, while playable on Low and Medium, show that the GPU is under significant stress at that resolution, particularly on Ultra where it dips below 60 FPS. This pattern is typical for a mid-range GPU paired with a capable mid-range CPU, where the balance shifts predictably as pixel workload increases.

Measured FPS Breakdown

At 1920x1080, the system delivers its highest performance across all settings. The Low preset achieves an average of 234.4 FPS, which is the maximum recorded for this combo. Medium follows closely at 216.4 FPS, High at 188.3 FPS, and Ultra at 152.2 FPS. These numbers indicate that the CPU is the primary limiting factor at this resolution, as the frame rates are high enough that the GPU is not fully saturated. The difference between Low and Ultra is 82.2 FPS, representing a 35% reduction in performance when enabling the highest settings.

Moving to 2560x1440, the frame rates remain robust but show a clear step down. The Low preset averages 159.6 FPS, Medium at 145.1 FPS, High at 129.9 FPS, and Ultra at 105.6 FPS. The spread between Low and Ultra is 54 FPS, which is a smaller absolute difference than at 1080p but a similar percentage gap. At this resolution, the GPU begins to exert more influence, particularly on Ultra settings where the frame rate drops below 110 FPS.

At 3840x2160, the performance curve flattens significantly. The Low preset averages 89.2 FPS, Medium at 82.1 FPS, High at 73 FPS, and Ultra at 55.6 FPS. The difference between Low and Ultra is 33.6 FPS, which is the smallest absolute gap of all three resolutions. This indicates that the GPU is fully saturated even on Low settings, and the frame rate is primarily determined by the card's raw throughput. The Ultra preset falls below 60 FPS, which may result in noticeable stuttering on 60 Hz displays, though the Low and Medium presets remain playable.

Across all resolutions, the scaling from Low to Ultra follows a similar pattern: each step up in settings reduces the average FPS by roughly 15-20%. However, the absolute impact becomes less severe at higher resolutions, as the GPU becomes the bottleneck and the relative cost of additional effects diminishes. The data shows that this combo is best suited for 1080p and 1440p gaming, where it can maintain high frame rates on any setting, while 4K is only viable on lower presets.

How This Combo Ranks

The Intel Core i5-10400F and NVIDIA GeForce GTX 1660 SUPER combination ranks 1593 out of 1800 tested combos for Roblox, placing it in the 12th percentile of all configurations. This ranking is notably lower than what the raw frame rates might suggest, indicating that many other systems achieve even higher performance in this specific title. The combo's position is influenced by the fact that Roblox is a highly scalable game that can leverage both high-end CPUs and GPUs effectively, allowing more powerful components to reach much higher frame rates.

Compared to the CPU's nearest rivals, the i5-10400F's average benchmark score of 14168 is 0.4% higher than the AMD EPYC 7552 (14115) and 1.1% higher than the Intel Core i5-8500 (14332). The GPU's average score of 14286 is 0.2% lower than the AMD Radeon RX Vega 11 (14314) and 0.7% lower than the AMD Radeon RX 5500 XT (14389). These small deltas suggest that the combo is closely matched with other mid-range systems, yet its ranking in Roblox is heavily influenced by how the specific combination of CPU and GPU interacts with the game's engine.

The rank of 1593 out of 1800 indicates that while this combo delivers playable performance, it falls short of the top tier in Roblox. This is likely due to the game's ability to utilize high core counts and fast memory subsystems, where more recent or higher-end components have an advantage. The data shows that the combo is capable of exceeding 100 FPS at 1080p and 1440p, which is sufficient for most players, but it does not compete with systems that can push beyond 300 FPS at those resolutions. The rank reflects this positioning, placing the combo in the lower third of tested configurations despite its solid real-world performance.
