Roblox

Roblox is not a typical stress test for high-end hardware, but the Intel Core i5-14400F and NVIDIA GeForce RTX 3070 combination produces a fascinating dataset that reveals a lot about how this specific pairing scales. The measured frames per second (FPS) figures are exceptionally high, indicating that this combo is far more than capable of delivering a smooth experience in this sandbox title. The data shows a clear progression of performance as resolution drops, and the relationship between the CPU and GPU becomes evident when examining the scaling efficiency across the three tested resolutions.

Resolution Scaling

The FPS scaling from 4K down to 1080p is aggressive, which is typical for a game like Roblox that is not graphically demanding by modern standards. At 4K Ultra, the combo averages 102 FPS. Dropping to 1440p Ultra yields 180 FPS, a substantial increase of 78 FPS. Moving down to 1080p Ultra nets 270 FPS, which is another 90 FPS gain over 1440p. This pattern of significant gains at every step down indicates that the system is not fully GPU-bound at lower resolutions, and the CPU's headroom allows the frame rate to balloon.

The gap between the Ultra and Low presets also widens as resolution decreases. At 4K, the difference between Low (156 FPS) and Ultra (102 FPS) is 54 FPS. At 1440p, that gap grows to 96 FPS, with Low hitting 276 FPS and Ultra at 180 FPS. At 1080p, the gap expands further to 143 FPS, with Low achieving 413 FPS and Ultra at 270 FPS. This widening delta suggests that at higher resolutions, the GPU is working harder to fill pixels, which slightly dampens the impact of the CPU-driven settings changes. Conversely, at 1080p, the GPU has so much spare capacity that the CPU and settings alterations have a more pronounced effect on the final output.

The limiting component shifts depending on the resolution. At 4K, the RTX 3070 is the primary bottleneck. The GPU's 8 GB of memory and its 448.0 GB/s bandwidth are being tasked with rendering over 8 million pixels, which is why the frame rates, while still high, are the lowest in the dataset. The CPU, with its 10 cores and 16 threads, is likely not breaking a sweat. At 1080p, the situation flips; the GPU is almost certainly idling, and the limit becomes the game engine's single-threaded performance and the CPU's ability to feed the renderer. The fact that the i5-14400F can push the Low preset to 413 FPS shows it has significant headroom in this title.

How This Combo Ranks

The combination ranks 1596 out of 3711 tested combos in Roblox. This places it in the upper-mid tier of all systems that have been benchmarked, which is a strong showing. The percentile position is more relevant when considering the sheer number of possible hardware combinations, many of which are likely less powerful. A rank of 1596 means that a majority of tested systems, roughly 57%, perform worse in this specific game. This is a solid result, indicating that the pairing is well-matched for Roblox, even if it is not at the absolute top of the leaderboard.

The rank is likely held back by the fact that Roblox can be heavily dependent on the CPU's single-core performance. While the i5-14400F is strong, its single-core Cinebench R23 score of 3055 and Geekbench single-core score of 2058 are good, but not exceptional, when compared to the top-tier CPUs that might be paired with other GPUs in the database. The GPU's 61st percentile ranking against all other GPUs is a bit lower than the CPU's 83rd percentile, but the game's engine seems to respond well to the combination's overall throughput. The data shows that this combo is a capable performer, placing it comfortably in the top half of all tested configurations.

CPU Role

The Intel Core i5-14400F is a 10-core, 16-thread processor based on the Raptor Lake architecture. Its base clock of 2.50 GHz and boost clock of 4.70 GHz are the key figures for this game. Roblox is known to be sensitive to single-threaded performance, and the CPU's boost clock of 4.70 GHz is crucial for achieving the high frame rates seen in the 1080p results. The measured 413 FPS on the Low preset at 1080p is a direct result of the CPU's ability to quickly process game logic and physics when the GPU is not a limiting factor.

The processor's 20 MB of shared L3 cache is also a benefit. This large pool of fast memory helps reduce latency when the CPU needs to access game data, which can contribute to more consistent frame times. The multi-threaded performance, while not the primary driver for Roblox, is still strong, with a Cinebench R23 multi-core score of 21645 and a Passmark multithread score of 25470. This ensures that background tasks or any minor threading in the game will not cause stutters. The CPU's 83rd percentile ranking against all CPUs confirms that it is a high-performing part, and its 0.2% deltaPct relative to the Intel Core i9-11900 and 0.5% versus the Core i7-12800H in the average benchmark score shows it is competitive with prior generation flagship mobile and desktop parts.

Measured FPS Breakdown

The measured FPS data provides a complete picture of performance across different settings and resolutions.

At 1920x1080, the lowest resolution tested, the combo produces staggering numbers. Low settings yield an average of 413 FPS, which is the highest in the entire dataset. Medium settings drop to 376 FPS, with a minimum of 320 FPS and a maximum of 432 FPS. High settings average 332 FPS, while Ultra settings average 270 FPS. Even at Ultra, the frame rate is nearly 3x higher than the refresh rate of a standard 144Hz monitor. The minimum FPS of 320 on Medium is higher than the average FPS of most other systems at this resolution.

Moving to 2560x1440, the performance scales down proportionally. Low settings average 276 FPS, Medium averages 251 FPS with a min of 213 and max of 289, High averages 222 FPS, and Ultra averages 180 FPS. These numbers are still exceptionally high, and the Ultra preset at 1440p offers a smoother experience than the High preset at 1080p on many other, less capable systems. The consistency is notable, with the gap between the average and minimum FPS on Medium being only 38 FPS.

At 3840x2160, the resolution is where the GPU starts to be taxed. Low settings average 156 FPS, Medium averages 142 FPS with a min of 121 and max of 163, High averages 125 FPS, and Ultra averages 102 FPS. The 4K Ultra result of 102 FPS is the only average below 120 FPS in the entire dataset. This shows that for a locked 4K 120Hz experience, users would need to lower the settings to High, which yields 125 FPS, to maintain a high refresh rate. The scaling from Low to Ultra at 4K is a 54 FPS drop, which is the smallest absolute difference of the three resolutions, reinforcing that the GPU is becoming the primary constraint.

GPU Role

The NVIDIA GeForce RTX 3070 is the graphics solution in this combo, and its role is clearly defined by the resolution scaling. The GPU's 8 GB of GDDR6 memory on a 256-bit bus provides 448.0 GB/s of bandwidth. This is sufficient for Roblox at any of the tested settings, as the game's textures and assets are not overly demanding. The GPU's 5888 shading units and 184 texture mapping units are more than enough to handle the rendering load at 1080p and 1440p, where the data shows it is not the bottleneck.

The RTX 3070's boost clock of 1725 MHz is the relevant figure for sustained performance. The GPU's 61st percentile ranking against all GPUs is a bit lower than the CPU's ranking, but it is the combination of the two that matters. In this game, the GPU's performance is only fully utilized at 4K, where the average FPS drops below the 200+ figures seen at lower resolutions. The data indicates that the GPU is a capable partner for the CPU, providing a solid foundation for high refresh rate gaming at 1440p and achieving playable 4K frame rates.

The GPU's high pixel rate of 165.6 GPixel/s and texture rate of 317.4 GTexel/s suggest it has the raw throughput to draw many objects quickly. However, in Roblox, the draw calls are often CPU-bound. The fact that the RTX 3070 can deliver 125 FPS at 4K High shows that it has enough power to render complex scenes without becoming a severe constraint. The GPU's score in Passmark G3D of 22214 and its 3DMark Steel Nomad DX12 score of 3162 reinforce its position as a strong mid-to-high-range card, but the game's engine does not seem to leverage its full potential until the pixel count is maximized.

Settings Recommendations

The best experience depends on the target display's resolution and refresh rate. For a 1080p 144Hz or 240Hz monitor, the data suggests using the Ultra preset. The average of 270 FPS is more than enough to saturate even a 240Hz panel, and the visual fidelity boost over Medium or High is worth the drop from the extreme 413 FPS seen on Low. The high frame rate is still nearly double the refresh rate of a 144Hz display, ensuring a perfectly smooth experience.

For a 1440p 144Hz monitor, the Ultra preset is also the recommended choice. The average of 180 FPS is above the 144Hz threshold, providing a 25% headroom that helps prevent frame drops during intense scenes. The Medium preset at 251 FPS is an option for those who prefer even higher frame rates, but the visual quality loss is not justified when Ultra already clears the target. The minimum FPS of 213 on Medium and the lack of a min FPS for Ultra suggest that Ultra is likely stable.

For a 4K 60Hz or 120Hz display, the recommendation changes. The Ultra preset at 4K averages 102 FPS, which is great for a 60Hz display but falls short of a 120Hz target. To achieve a steady 120 FPS, the High preset is the better choice, with an average of 125 FPS. This provides a comfortable buffer. If a 4K 60Hz display is the target, the Ultra preset is a viable option, as 102 FPS is well above the refresh rate. The data shows that the High preset is the sweet spot for 4K high-refresh-rate gaming, offering a 23% performance increase over Ultra while maintaining a high level of visual quality.
