Roblox

Roblox, a sandbox title from 2006, presents an unusual benchmarking scenario for the Intel Core i7-14700K and NVIDIA GeForce RTX 5090 D combination. The measured frame rates are exceptionally high across all settings, indicating that this pairing is overwhelmingly powerful for the game's engine. The data reveals a system that is heavily bottlenecked by CPU performance at lower resolutions, while the GPU begins to assert its influence only at higher graphical presets and 4K resolution.

Resolution Scaling

The transition from 1080p to 4K demonstrates a classic performance curve, but the absolute numbers are so high that the scaling factors are more telling than the raw FPS. At High settings, the average frame rate drops from 625 FPS at 1920x1080 to 417 FPS at 2560x1440, a reduction of 33.3%. Moving from 1440p to 3840x2160 sees a further drop to 236 FPS, which is a 43.4% decrease from the 1440p result. This steep decline suggests that the game becomes progressively more demanding on the GPU as pixel count increases, moving away from a CPU-limited scenario.

The pattern is consistent across other presets. At Low settings, the frame rate falls from 776 FPS at 1080p to 518 FPS at 1440p, and then to 293 FPS at 4K. The percentage drops are 33.2% and 43.4% respectively, mirroring the High setting behavior almost exactly. This consistency indicates that the scaling is driven by resolution, not by the specific graphical features toggled by the preset.

At Ultra settings, the scaling is even more pronounced. The 1080p result is 507 FPS, which drops to 338 FPS at 1440p (a 33.3% decrease) and then to 191 FPS at 4K (a 43.5% decrease from 1440p). The near-identical percentage drops across all presets—roughly one-third from 1080p to 1440p and another 43% from 1440p to 4K—indicate that the primary limiting factor shifts from the CPU to the GPU as resolution increases. The CPU is capable of feeding the GPU with enough data to achieve over 700 FPS at 1080p, but the GPU's rendering workload at 4K becomes the constraining element, pulling the average down to a still-impressive 191-293 FPS depending on the preset.

Settings Recommendations

The measured data provides clear guidance for optimizing the experience. At 1920x1080, the Ultra preset delivers an average of 507 FPS, which is more than sufficient for any high-refresh-rate monitor. The High preset at this resolution yields 625 FPS, but the visual difference between High and Ultra may not justify the 118 FPS loss for most users. However, given the immense headroom, using Ultra at 1080p is the most sensible choice for maximum visual quality.

At 2560x1440, the Ultra preset achieves 338 FPS, which is still exceptionally high. The High preset offers 417 FPS, a 23.4% increase. For competitive play, the High preset provides a significant frame rate advantage with minimal visual compromise. For a more visually rich experience, Ultra remains viable at this resolution, as 338 FPS is far beyond the refresh rate of most monitors.

At 3840x2160, the choice becomes more nuanced. The Ultra preset drops to 191 FPS, which is still smooth but represents a 19.1% decrease from the High preset's 236 FPS. The Medium preset offers 267 FPS with a minimum of 227 FPS, making it a strong candidate for 4K gaming. The Low preset provides 293 FPS, but the visual quality reduction is substantial. The data suggests that the High preset at 4K is the optimal balance, as it provides a high frame rate with better visual fidelity than Medium or Low. This combination is so powerful that even at 4K Ultra, the game remains highly playable, but the High preset is recommended for the best combination of image quality and performance.

GPU Role

The NVIDIA GeForce RTX 5090 D is a Blackwell 2.0 architecture GPU with a massive 32 GB of GDDR7 memory on a 512-bit bus, providing 1.79 TB/s of bandwidth. Its base clock is 2017 MHz with a boost clock of 2407 MHz. These specifications translate into a peak FP32 performance of 104.8 TFLOPS. In Roblox, this level of compute power is far beyond what is required for the game's rendering tasks, as evidenced by the high frame rates even at 4K Ultra.

The GPU's role is most apparent at higher resolutions. At 1080p, the frame rates are likely limited by the CPU, as the GPU has ample headroom to render frames quickly. The scaling from 1080p to 1440p shows a consistent one-third reduction in FPS, which is a classic sign of the GPU becoming more involved. The further drop to 4K, with another 43% reduction, indicates that the GPU is now the primary bottleneck. The RTX 5090 D's performance in this game is so high that even at 4K, it maintains over 190 FPS on Ultra settings.

The GPU's memory capacity of 32 GB is not a limiting factor in Roblox, as the game is likely to use only a fraction of it. The transistor count of 92,200 million on a 750 mm² die highlights the immense complexity of the chip, but its real-world performance in this title is what matters. The benchmark results, including a 3DMark Steel Nomad score of 14,326 and a Geekbench Vulkan score of 376,915, confirm that the GPU is a top-tier performer, and its role in this combo is to provide the rendering headroom that allows for high frame rates at demanding resolutions.

Measured FPS Breakdown

The measured frame rates provide a comprehensive view of the combo's performance. At 1920x1080, the average FPS is 776 on Low, 706 on Medium, 625 on High, and 507 on Ultra. The Medium preset has a minimum of 600 FPS and a maximum of 812 FPS. At 2560x1440, the averages are 518 on Low, 471 on Medium, 417 on High, and 338 on Ultra. The Medium preset at this resolution shows a minimum of 401 FPS and a maximum of 542 FPS. At 3840x2160, the averages drop to 293 on Low, 267 on Medium, 236 on High, and 191 on Ultra. The 4K Medium preset has a minimum of 227 FPS and a maximum of 307 FPS.

These numbers demonstrate a clear hierarchy. The Low preset at 1080p is the fastest, while the Ultra preset at 4K is the slowest. The gap between the fastest and slowest measured points is 585 FPS, which confirms the wide range of performance depending on the configuration. The data shows that the Medium preset consistently provides a middle ground between Low and High, with the 4K Medium result of 267 FPS being particularly notable for its high minimum frame rate of 227 FPS. This suggests that Medium is a stable choice for maintaining high frame rates without significant dips.

CPU Role

The Intel Core i7-14700K is a 20-core, 28-thread processor based on the Raptor Lake architecture. It has a base clock of 3.40 GHz and a boost clock of 5.60 GHz. Its 33 MB of shared L3 cache and support for both DDR4 and DDR5 memory make it a versatile and powerful CPU. In Roblox, its role is crucial at lower resolutions where the game's logic and physics calculations can become a bottleneck. The high single-thread performance, evidenced by a Cinebench R23 score of 2,160 and a Passmark single-thread score of 4,472, is particularly important for a game like Roblox.

The CPU's multi-core performance is also exceptional, with a Cinebench R23 multi-core score of 33,440.5 and a Geekbench multi-core score of 20,767. However, the game likely does not utilize all 20 cores efficiently, making the single-thread performance more critical. The data supports this: at 1080p, the frame rates are extremely high, but they are capped by the CPU's ability to process the game's update loop. The fact that the FPS scales down only when resolution increases, not when settings are lowered, confirms that the CPU is the limiting factor at 1080p.

The CPU's 94th percentile ranking and its average benchmark score of 69,355 place it among the best processors available. Its nearest rival, the AMD Ryzen 9 7950X, has a score of 69,515, which is only 0.2% higher, indicating they are nearly equivalent in general benchmarks. In Roblox, the i7-14700K's combination of high single-thread performance and sufficient multi-core power ensures that it can feed the RTX 5090 D with enough data to achieve the top rank in this game. The CPU's boost clock of 5.60 GHz is likely a key factor in its ability to maintain high frame rates in CPU-bound scenarios.
