Roblox

The Intel Core i9-14900K paired with the NVIDIA GeForce RTX 4080 SUPER delivers exceptional performance in Roblox, with frame rates that far exceed typical display refresh rates across all tested resolutions and settings. This combination ranks in the top percentile of all tested combos, demonstrating that even a demanding CPU and high-end GPU pairing is more than sufficient for this sandbox title.

Resolution Scaling

The benchmark data reveals a clear and predictable pattern of frame rate scaling as resolution increases from 1080p to 4K. At 1080p with Low settings, the combo achieves an average of 638.7 FPS, which drops to 429.5 FPS at 1440p and further to 239.9 FPS at 4K. This represents a substantial 62.4% reduction in frame rate from 1080p Low to 4K Low, indicating that the GPU becomes progressively more stressed as pixel count increases.

The scaling behavior differs notably across quality presets. At Ultra settings, the frame rate drops from 419.2 FPS at 1080p to 279 FPS at 1440p, then to 154.5 FPS at 4K—a total reduction of 63.2% from 1080p to 4K. The High preset shows similar characteristics, with 513.9 FPS at 1080p falling to 341.3 FPS at 1440p and 194.8 FPS at 4K, representing a 62.1% decline. Medium settings follow the same trend: 580.9 FPS at 1080p, 389.6 FPS at 1440p, and 217.6 FPS at 4K.

These percentages reveal that Roblox scales almost linearly with pixel count, suggesting the workload is heavily GPU-bound at higher resolutions. However, the absolute frame rates remain remarkably high—even the lowest measured result of 154.5 FPS at 4K Ultra exceeds the refresh rate of most high-end monitors. The CPU's 24 cores and 32 threads, with a boost clock of 6.00 GHz, provide ample headroom to feed the GPU even at 1080p where CPU bottlenecking typically occurs. The data indicates that at 1080p, the frame rates are so high that the limiting factor shifts between CPU and GPU depending on the preset, but the system never falls below playable thresholds.

GPU Role

The RTX 4080 SUPER's specifications directly support the observed performance levels. Its 16 GB of GDDR6X memory on a 256-bit bus provides 736.3 GB/s of bandwidth, which is more than sufficient for Roblox's modest texture and geometry requirements. The GPU's boost clock of 2550 MHz, combined with its 10240 shading units and 112 ROPs, delivers the raw compute power needed to sustain the high frame rates seen in the benchmarks.

The GPU's memory configuration is particularly relevant here. Roblox is not a memory-intensive title, and the 16 GB frame buffer remains largely underutilized even at 4K with Ultra settings. The measured frame rates show that the GPU's compute capacity, rather than its memory subsystem, is the primary factor driving performance. The 52.22 TFLOPS of FP32 performance and 816.0 GTexel/s texture rate ensure that even complex scenes with many objects and effects render smoothly.

Interestingly, the GPU's performance percentile of 88 versus all GPUs, combined with its average benchmark score of 53610, places it in the upper tier of graphics cards. The nearest rival, the AMD Radeon RX 6900 XT, scores 53489—a mere 0.2% difference—while the NVIDIA GeForce RTX 5070 Ti trails by 2.9% with a score of 52086. This close competition at the top of the GPU hierarchy means the RTX 4080 SUPER's performance in Roblox is consistent with its overall standing, though the game's low graphical demands mean even mid-range cards could achieve high frame rates here.

How This Combo Ranks

This specific combination of the Intel Core i9-14900K and RTX 4080 SUPER ranks 146th out of 1800 tested combos for Roblox, placing it in the top 8.1% of all configurations. This ranking reflects the high absolute performance of both components, but it also suggests that many other combinations can achieve similar results in this undemanding title. The CPU's percentile of 97 versus all CPUs, with an average benchmark score of 79824, places it among the fastest processors available, narrowly edging out the AMD EPYC 7413 by 0.3% and the Intel Core i9-14900KF by 0.7%.

The GPU's contribution to this ranking is equally significant. With a percentile of 88 versus all GPUs, the RTX 4080 SUPER is a high-end part, but it is not the absolute fastest. The data shows that the combo's ranking is more heavily influenced by the CPU's exceptional performance, since Roblox is a CPU-sensitive game in many scenarios. The gap between this combo and the top-ranked configurations likely stems from both components' positions in their respective performance hierarchies—the CPU is near the top, while the GPU sits slightly below the flagship tier.

What this ranking means in practical terms is that users can expect exceptionally smooth gameplay without any frame rate concerns. The lowest recorded average of 154.5 FPS at 4K Ultra is still well above the 60 FPS standard for most displays, and the 1080p results exceed 400 FPS even at the highest preset. For esports or competitive play where frame rates above 300 FPS are desirable, this combo delivers at 1080p and 1440p across all settings.

Settings Recommendations

The measured frame rates provide clear guidance on the optimal settings configuration. At 4K, the Ultra preset delivers 154.5 FPS, while High achieves 194.8 FPS, Medium reaches 217.6 FPS, and Low produces 239.9 FPS. The differences between presets are substantial, with Ultra being 28.6% slower than High, and High being 18.9% slower than Medium. Given that Roblox's visual differences between High and Ultra are often subtle, the High preset at 4K offers the best balance of visual quality and performance, delivering nearly 200 FPS.

At 1440p, the recommendation shifts. Ultra achieves 279 FPS, which is already excellent for high-refresh-rate monitors. The jump to High yields 341.3 FPS, a 22.3% improvement, while Medium and Low reach 389.6 and 429.5 FPS respectively. For users with 144Hz or 165Hz displays, the Ultra preset at 1440p is perfectly adequate, but those with 240Hz panels should consider High to ensure frame rates stay above the refresh rate ceiling. The Medium preset provides a comfortable margin for 360Hz displays.

At 1080p, all presets deliver frame rates above 400 FPS, with Low hitting 638.7 FPS, Medium at 580.9 FPS, High at 513.9 FPS, and Ultra at 419.2 FPS. Even the Ultra preset exceeds the capabilities of most gaming monitors, which typically cap at 360Hz. The data suggests that at 1080p, users can select Ultra without any meaningful performance penalty, since the minimum frame rate of 419.2 FPS is still far beyond display capabilities. The Medium preset offers the best performance headroom for future content updates or more demanding user-created games.
