Roblox

Roblox is a massively popular Sandbox title that has been live since 2006, and its performance characteristics differ greatly from typical AAA releases. The combination of the Intel Core i5-14400F and the NVIDIA GeForce RTX 5080 produces exceptionally high frame rates across all tested configurations. The data set shows this pairing achieving a combo rank of 77 out of 1800 tested combos, placing it in the top percentile of all systems evaluated for this game, indicating that this hardware pairing is exceptionally well-suited for the workload.

How This Combo Ranks

The benchmark database places this specific CPU and GPU pairing at rank 77 out of 1800 total combos tested for Roblox. This is a strong showing, placing the system in the top 4.3% of all configurations. The position reflects the balance between the processor's capability to feed frames and the graphics card's ability to render them at high speed. This rank is particularly impressive given the game's age and its tendency to be more sensitive to single-core performance than multi-core scaling. The data indicates that the system sits above the vast majority of tested hardware, making it a high-end solution for this title. The high rank is consistent with the measured FPS, which exceed the refresh rates of most displays even at elevated resolutions, suggesting that the limiting factor for a user would be the display's capabilities rather than the hardware's performance ceiling.

CPU Role

The Intel Core i5-14400F is a 10-core, 16-thread processor from the Core 14th Gen series, built on the Raptor Lake architecture. It operates with a base clock of 2.50 GHz and a boost clock of 4.70 GHz. For a game like Roblox, which often relies on a limited number of threads for core game logic and physics, the processor's strong single-thread performance is critical. The benchmark data supports this, with a Cinebench R23 single-core score of 3093 and a Passmark single-thread score of 3723, indicating robust per-core performance. The processor's 20 MB of shared L3 cache helps reduce latency when accessing frequently used game data. The CPU's overall average benchmark score of 32508 places it in the 88th percentile of all CPUs, and its nearest rival, the Intel Core i7-12800H, has a nearly identical average score of 32513, showing that the i5-14400F provides top-tier processing power. In the measured FPS data, the impact of the CPU is most visible at 1080p resolution, where the system reaches an average of 681.6 FPS on Low settings, a number so high that it is likely constrained by the game's engine or the CPU's frame generation limit rather than the GPU.

GPU Role

The NVIDIA GeForce RTX 5080 is a high-end graphics card based on the Blackwell 2.0 architecture. It features 16 GB of GDDR7 memory on a 256-bit bus, providing a substantial memory bandwidth of 960.0 GB/s. The GPU operates at a base clock of 2295 MHz and a boost clock of 2617 MHz. With 10752 shading units, the card is equipped for massive parallel workloads. Its Passmark G3D score of 36565 demonstrates immense raw graphics power, placing it in the 89th percentile of all GPUs. The nearest rival in terms of average benchmark score is the Intel Arc A570M, which has a score of 58239, while the RTX 5080's own average benchmark score is 59188, making it 1.6% faster than that rival. This level of GPU performance ensures that the card is rarely the bottleneck in Roblox, as evidenced by the FPS data scaling directly with resolution and settings. The GPU's 16 GB of VRAM is more than sufficient for Roblox's asset sizes, ensuring that texture loading does not cause hitches or frame drops in the measured scenarios.

Measured FPS Breakdown

The measured FPS data provides a clear picture of performance across three resolutions and four settings presets. At 1920x1080, the system achieves an average of 681.6 FPS on Low settings, 621.6 FPS on Medium, 548.8 FPS on High, and 441.5 FPS on Ultra. These numbers are extraordinarily high, indicating that the hardware is far beyond the requirements for smooth gameplay at this resolution. Moving to 2560x1440, the averages remain very high: 457.7 FPS on Low, 415.2 FPS on Medium, 366.5 FPS on High, and 295.7 FPS on Ultra. The drop from 1080p to 1440p is significant but still leaves the system far above the 144Hz threshold that many high-refresh monitors use. At 3840x2160, the performance is still impressive, with an average of 260.7 FPS on Low, 232.2 FPS on Medium, 207.8 FPS on High, and 169.1 FPS on Ultra. Even at 4K Ultra, the system maintains a frame rate that is well above 144 FPS, ensuring a fluid experience on the most demanding settings tested. The data shows a consistent scaling pattern where each increase in settings or resolution yields a predictable decrease in FPS, with the gap between Low and Ultra widening as resolution increases.

Resolution Scaling

The scaling from 1080p to 4K reveals the limiting component dynamics for this combination. At 1080p Low, the system produces 681.6 FPS, which drops by approximately 32.8% to 457.7 FPS at 1440p, and then further by 43.0% to 260.7 FPS at 4K. This scaling pattern indicates that the CPU is the primary limiter at 1080p, as the GPU has enough headroom to render frames faster than the CPU can issue draw calls. The evidence for this is that the FPS at 1080p Low is substantially higher than at 1080p Ultra, but the GPU load is likely not saturated. As the resolution increases to 4K, the FPS drops significantly, showing that the GPU becomes the limiting factor. The drop from 1080p Low to 4K Low is 61.7%, which is a substantial decrease that aligns with the increased pixel count. The same trend is visible across all settings, but the absolute FPS numbers remain high enough that the system never drops below the 144 FPS threshold, even at 4K Ultra. This suggests that for users with high-refresh-rate 4K displays, the combination is well-balanced, though the CPU does constrain maximum FPS at lower resolutions.

Settings Recommendations

Based on the measured rows, the optimal settings depend heavily on the user's display refresh rate and resolution preference. For 1920x1080 displays, the data shows that even the Ultra preset, which yields 441.5 FPS, is far beyond the capabilities of most monitors, which typically cap at 240Hz or 360Hz. Therefore, users with a 1080p 240Hz monitor can safely enable Ultra settings and still have a massive FPS buffer. For 2560x1440, the Ultra preset produces 295.7 FPS, which is again sufficient for the fastest 1440p monitors on the market. The High preset at 366.5 FPS offers a slight performance gain but no visual benefit that would justify the difference. For 3840x2160, the Ultra preset delivers 169.1 FPS, which is still above the 144Hz refresh rate of most 4K gaming monitors. This means that for a 4K 144Hz display, the Ultra preset is the best choice, as it provides the highest visual fidelity while maintaining a frame rate that exceeds the display's refresh rate. The data suggests that the Low and Medium presets are unnecessary for this hardware, as the High and Ultra presets already provide performance that is more than adequate for any current display technology. The choice between High and Ultra should be made based on visual preference, as the performance difference is minimal in absolute terms, but Ultra offers the best experience per the measured rows.
