Roblox

The Intel Core i5-14400F paired with the NVIDIA GeForce RTX 4080 SUPER delivers a massive performance envelope in Roblox, one that is almost entirely dictated by the resolution you choose to target. The measured data shows a clear and predictable scaling pattern as pixel count increases, moving from a CPU-bound scenario at 1080p to a more balanced, though still GPU-heavy, workload at 4K.

At 1920x1080, the frame rates are astronomical, reaching a peak of 638 FPS on Low settings. This suggests that the game engine’s draw calls and physics calculations are being handled with immense headroom by the 10-core, 16-thread processor. The gap between Low and Ultra at this resolution is 221.6 FPS, which is substantial, but the absolute numbers indicate that the bottleneck is the game’s single-threaded performance ceiling rather than the hardware’s raw capability. Moving to 2560x1440, the average FPS across all settings drops by roughly 33% compared to 1080p, but the curve remains high, with Low settings still producing 427.4 FPS and Ultra maintaining 275.6 FPS.

The transition to 3840x2160 is where the scaling becomes more aggressive and tells a different story. Here, the 4K Ultra preset falls to 157.5 FPS, a 62% reduction from the 1080p Ultra score. Meanwhile, 4K Low still manages a blistering 240.2 FPS. This delta of 82.7 FPS between the lowest and highest quality settings at 4K indicates that the RTX 4080 SUPER’s shading units and memory bandwidth are becoming the primary limiting factor, though the frame rates remain exceptionally playable for a competitive or casual title. The data suggests that while the CPU is strong enough to feed the GPU at lower resolutions, the 4080 SUPER’s 16 GB of GDDR6X memory and 736.3 GB/s bandwidth are what keep the experience fluid when the pixel shader workload increases.

How This Combo Ranks

Within the database’s extensive collection of tested hardware combinations, this specific pairing of the i5-14400F and RTX 4080 SUPER holds a strong position for Roblox. The combo ranks 151st out of 1800 tested configurations, placing it in the top 8.4% of all systems. This is a statistically significant performance tier, indicating that the combination of the processor’s high single-core boost clock of 4.70 GHz and the GPU’s massive compute throughput is well-suited for this game’s engine.

The processor itself sits in the 88th percentile against all CPUs, with an average benchmark score of 32508. Its nearest rivals include the Intel Core i7-12800H with a score of 32513 (a negligible 0% delta) and the AMD Ryzen 5 PRO 7645 at 32446 (0.2% slower). This shows that the i5-14400F is performing at the top of its class, essentially matching mobile high-end chips and beating them by fractions of a percent. The GPU also lands in the 88th percentile against all GPUs, with an average score of 53610. Its closest competitor, the AMD Radeon RX 6900 XT, scores 53489, which is only 0.2% slower, while the RTX 5070 Ti trails by 2.9%.

The rank of 151 suggests that while this is not the absolute fastest combo possible, it is far from a bottleneck. The data indicates that the i5-14400F is not holding back the RTX 4080 SUPER in this specific title, as the rank is more dependent on the GPU’s raw power than the CPU’s position in the hierarchy. The fact that the CPU’s rivals are all within a 0.2% margin of each other reinforces that Roblox’s performance is more sensitive to the graphics card once you have a modern mid-range or higher processor.

GPU Role

The NVIDIA GeForce RTX 4080 SUPER is the dominant component in this pairing, and its specifications directly correlate with the measured frame rates. The card operates on the Ada Lovelace architecture with a boost clock of 2550 MHz, and it is backed by 16 GB of GDDR6X memory on a 256-bit bus, yielding a bandwidth of 736.3 GB/s. These figures are critical for Roblox, which, despite its blocky aesthetic, can generate significant geometry and texture data at high resolutions and Ultra settings.

In the measured FPS data, the GPU’s role becomes evident when comparing the 1080p and 4K results. At 1080p Low, the score of 638 FPS is far beyond the refresh rate of any mainstream monitor, indicating that the GPU is idle much of the time, waiting for the CPU to submit draw calls. However, at 4K Ultra, the score drops to 157.5 FPS, which is a direct consequence of the GPU’s pixel fill rate and memory throughput being taxed by the higher resolution. The RTX 4080 SUPER’s 112 ROPs and 816.0 GTexel/s texture rate are being utilized heavily here, but the card still has enough headroom to push past 144 FPS.

The GPU’s benchmark scores corroborate this performance. It achieves a Passmark G3D score of 34245 and a 3DMark Steel Nomad DX12 score of 6600. These numbers place it just ahead of the Radeon RX 6900 XT in raw compute, which aligns with the in-game results where the 4080 SUPER never drops below 157 FPS even under maximum load at 4K. The 16 GB VRAM allocation is also a non-factor in this game, as Roblox does not typically consume that much memory, but it ensures that there is no capacity bottleneck that could cause stuttering at higher settings.

Settings Recommendations

The measured FPS data suggests that the optimal experience depends entirely on your display’s refresh rate and resolution. For users with a 4K 144Hz monitor, the High preset is the sweet spot, delivering an average of 197.1 FPS. This provides a significant buffer above 144 FPS, ensuring smooth gameplay even during complex scenes with many players. The Ultra preset at 4K drops to 157.5 FPS, which is still above 144Hz, but the margin is thinner, and any physics-heavy moments could cause dips below that threshold.

For 1440p users with a 240Hz display, the Medium preset is the best choice, averaging 386.7 FPS. This leaves ample headroom to stay above 240 FPS in most situations. The High preset at 341.1 FPS is also viable, but Medium offers a better balance between visual fidelity and raw frame rate, especially if you are playing competitive modes where responsiveness is key. The Low preset at 427.4 FPS is overkill for most displays and sacrifices too much visual quality.

At 1080p, the story changes. The Low preset achieves 638 FPS, which is only useful for esports players on 360Hz or higher monitors. For the vast majority of users with a 240Hz or 144Hz display, the Ultra preset at 416.4 FPS is the recommended choice. It provides the highest visual quality while still delivering frame rates that far exceed any refresh rate on the market. The data shows no reason to drop below High at 1080p, as even that preset yields 511.8 FPS, which is more than enough for any competitive scenario.

Measured FPS Breakdown

The complete set of measured results provides a clear picture of how the i5-14400F and RTX 4080 SUPER scale across resolutions and settings.

At 1920x1080, the Low preset yields an average of 638 FPS. This is the highest score recorded in the entire dataset, indicating that the CPU is the limiting factor here, as the GPU is not being fully utilized. The Medium preset drops to 578.8 FPS, a 9.3% reduction, while High produces 511.8 FPS, an 11.6% further reduction. Ultra at 1080p delivers 416.4 FPS, which is a 34.8% decrease from Low, showing that the game’s visual effects (shadows, lighting, anti-aliasing) do have a measurable impact even at this resolution.

At 2560x1440, the scaling is more uniform. Low averages 427.4 FPS, Medium 386.7 FPS (a 9.5% drop), High 341.1 FPS (a 11.8% drop), and Ultra 275.6 FPS (a 19.2% drop from High). The absolute frame rates remain high, but the percentage deltas between settings are larger than at 1080p, indicating that the GPU is starting to take on a more significant workload as the pixel count increases.

At 3840x2160, the GPU is clearly the primary driver. Low averages 240.2 FPS, Medium 220.3 FPS (an 8.3% drop), High 197.1 FPS (a 10.5% drop), and Ultra 157.5 FPS (a 20.1% drop from High). The overall reduction from 1080p Low to 4K Low is 62.4%, and from 1080p Ultra to 4K Ultra is 62.2%. This consistency in relative scaling suggests that the RTX 4080 SUPER’s memory bandwidth is the bottleneck at 4K, as the GPU’s compute capacity is more than sufficient for the game’s geometry, but the pixel data transfer rate limits how fast frames can be rendered.
