Roblox

Roblox with the Intel Core i5-10400F and NVIDIA GeForce RTX 5090 D produces exceptionally high frame rates across all tested configurations. The data shows a system that is overwhelmingly capable of running this sandbox title at maximum refresh rates, though the performance scaling between resolutions reveals a clear shift in bottleneck behavior. The measured results indicate that at lower resolutions, the CPU becomes the limiting factor, while the GPU takes over as the primary constraint at 4K. This analysis walks through the resolution scaling, component roles, and measured frame rates to provide a complete picture of this combination's capabilities.

Resolution Scaling

The frame rate progression from 1080p to 4K demonstrates the expected inverse relationship between resolution and performance, but the magnitude of the drop varies significantly depending on the graphics preset. At Ultra settings, the average frame rate falls from 500 FPS at 1920x1080 to 338 FPS at 2560x1440, a reduction of 162 FPS, and then further down to 191 FPS at 3840x2160. This represents a 61.8% decrease from the 1080p figure to the 4K figure, indicating that the GPU is handling a substantially larger workload at higher pixel counts. The scaling at High settings follows a similar pattern, with averages of 539 FPS, 417 FPS, and 236 FPS across the three resolutions, which translates to a 56.2% drop from the lowest to the highest resolution.

The Low preset presents an interesting contrast, as the frame rates remain remarkably high even at 4K. The average FPS at 1920x1080 is 581, dropping to 508 at 2560x1440 and then to 293 at 3840x2160. The reduction from 1080p to 4K here is 49.6%, which is smaller than the drops seen at higher settings. This suggests that at Low settings, the rendering load is light enough that the system is not purely GPU-bound at lower resolutions. The Medium preset shows the most linear scaling, with averages of 563 FPS, 471 FPS, and 267 FPS, representing a 52.6% decrease from 1080p to 4K. The consistent scaling across Medium indicates a balanced load between the CPU and GPU as resolution increases.

The gap between Low and Ultra settings widens dramatically at higher resolutions. At 1080p, the difference between Low (581 FPS) and Ultra (500 FPS) is only 81 FPS, suggesting that the CPU is limiting performance at the lowest settings. At 4K, the gap expands to 102 FPS between Low (293 FPS) and Ultra (191 FPS), showing that the GPU now has more room to demonstrate its capabilities. This pattern is classic evidence of a CPU bottleneck at lower resolutions, where the processor cannot feed frames fast enough to fully utilize the GPU, followed by a GPU bottleneck at 4K where the rendering workload becomes the constraint. The data indicates that Roblox is not particularly demanding on either component, but the balance shifts as pixel count increases.

Q: How does the combo rank among all tested combinations in Roblox?

A: This combination of Intel Core i5-10400F and NVIDIA GeForce RTX 5090 D ranks 121st out of 3010 tested combos in Roblox. This places it in the top 4% of all tested configurations, indicating excellent performance despite the potential CPU bottleneck.

GPU Role

The NVIDIA GeForce RTX 5090 D brings substantial resources to this title, with 32 GB of GDDR7 memory on a 512-bit bus providing 1.79 TB/s of bandwidth. The GPU's base clock is 2017 MHz, with a boost clock of 2407 MHz, and the memory operates at 1750 MHz with 28 Gbps effective speed. These specifications are far beyond what Roblox typically requires, yet the measured frame rates show that the GPU still has a significant impact on performance at higher resolutions and settings. The card's 21760 shading units and 680 texture mapping units allow it to process the game's geometry and effects with ease, while the 176 render output units handle pixel throughput efficiently.

The GPU's role becomes more apparent when examining the frame rate scaling from 1080p to 4K. At Ultra settings, the drop from 500 FPS to 191 FPS represents a 61.8% decrease, which is a substantial reduction that indicates the GPU is working much harder at higher pixel counts. The memory bandwidth of 1.79 TB/s ensures that texture fetching and data transfer do not become bottlenecks, even at 4K with High or Ultra settings. The 32 GB VRAM capacity is more than sufficient for Roblox, which is not a memory-intensive title, so the frame rate differences across settings are primarily due to compute and pixel shading load rather than memory constraints.

The RTX 5090 D's benchmark scores position it as a top-tier GPU, with a percentile of 92 among all GPUs and an average benchmark score of 77712. Its nearest rivals in synthetic testing are all within a narrow margin of 2.4%, showing that the card is not dramatically ahead of its peers in raw compute. In Roblox specifically, the GPU appears to be the limiting factor at 4K Ultra, where the average FPS of 191 is the lowest recorded in the dataset. This suggests that the game's rendering pipeline can stress even a flagship GPU when pushed to maximum settings at high resolution, although the absolute frame rates remain very high by most standards.

Measured FPS Breakdown

The measured frame rate data provides a comprehensive view of the system's performance across all combinations of resolution and settings. At 1920x1080, the average frame rates are 581 FPS for Low, 563 FPS for Medium, 539 FPS for High, and 500 FPS for Ultra. The Medium preset also includes a minimum of 478 FPS and a maximum of 647 FPS, showing a tight range that indicates stable performance. The difference between the lowest and highest settings at 1080p is 81 FPS, which is relatively modest and points to CPU limitation as the primary constraint at this resolution.

Moving to 2560x1440, the average frame rates are 508 FPS for Low, 471 FPS for Medium, 417 FPS for High, and 338 FPS for Ultra. The Medium preset reports a minimum of 401 FPS and a maximum of 542 FPS. The gap between Low and Ultra widens to 170 FPS, demonstrating that the GPU becomes more involved in performance determination as the resolution increases. The percentage drop from 1080p to 1440p for each setting is 12.6% for Low, 16.3% for Medium, 22.6% for High, and 32.4% for Ultra, showing that higher settings experience larger relative reductions.

At 3840x2160, the average frame rates drop to 293 FPS for Low, 267 FPS for Medium, 236 FPS for High, and 191 FPS for Ultra. The Medium preset shows a minimum of 227 FPS and a maximum of 307 FPS. The gap between Low and Ultra at 4K is 102 FPS, which is smaller than at 1440p but still significant. The percentage drop from 1440p to 4K is 42.3% for Low, 43.3% for Medium, 43.4% for High, and 43.5% for Ultra. This consistency across settings suggests that at 4K, the scaling is largely uniform and driven by pixel count rather than specific settings. The frame rates at 4K remain above 191 FPS in all cases, which is more than sufficient for smooth gameplay on high-refresh-rate monitors.

How This Combo Ranks

The combination of Intel Core i5-10400F and NVIDIA GeForce RTX 5090 D achieves a rank of 121 out of 3010 tested combos in Roblox. This places the configuration in the top 4.0% of all tested combinations, which is an exceptional result given the potential CPU bottleneck identified in the resolution scaling analysis. The high rank is likely driven by the GPU's immense power, as the RTX 5090 D's 92nd percentile among all GPUs ensures that the system can maintain high frame rates even at demanding settings. The CPU's 68th percentile ranking is lower, but it does not appear to drag the combo down significantly in this particular game.

The rank of 121 suggests that there are 120 other combinations that perform better in Roblox, which could include configurations with more powerful CPUs paired with the same GPU. However, the measured frame rates show that this combo still delivers over 500 FPS on average at 1080p and over 190 FPS at 4K Ultra, so the practical difference between this and higher-ranked combos is likely minimal. The data indicates that the combo is well-suited for Roblox, with frame rates that far exceed display refresh rates in all tested scenarios. The rank relative to 3010 combos is a strong indicator of the system's capability, placing it in the upper echelon of tested configurations.

CPU Role

The Intel Core i5-10400F is a 6-core, 12-thread processor with a base clock of 2.90 GHz and a boost clock of 4.30 GHz. It is built on the Comet Lake architecture using a 14 nm process node and supports DDR4 memory in dual-channel configuration. The CPU has 12 MB of shared L3 cache and 256 KB of L2 cache per core, with a TDP of 65 watts. Its benchmark scores are moderate, with a passmark multithread score of 12115 and a passmark single-thread score of 2541. The CPU's percentile of 68 among all CPUs indicates it performs better than the majority of processors, but it is not a top-tier gaming chip.

In Roblox, the CPU's role is most evident at lower resolutions where the frame rates cluster closely together regardless of graphics settings. At 1080p, the difference between Low and Ultra is only 81 FPS, suggesting that the CPU cannot supply frames fast enough to differentiate between settings. The 3dmark single-thread score of 688 and 3dmark 2-thread score of 1350 provide context for the CPU's gaming performance, as Roblox's physics and game logic may rely on single or low-thread-count workloads. The cinebench r23 single-core score of 1451 further indicates the CPU's capability in lightly threaded tasks.

The CPU's 6 cores and 12 threads are sufficient for Roblox, which is not a heavily multithreaded title. The passmark data compression score of 185944 and integer math score of 41471 show the CPU's general processing power, but these are not directly relevant to gaming performance. The fact that the combo ranks 121st out of 3010 suggests that the CPU does not significantly hamper the GPU's performance in Roblox, even if it is the limiting factor at 1080p. The boost clock of 4.30 GHz helps maintain high single-thread performance, which is often the most important metric for game simulation and physics updates.

Settings Recommendations

Based on the measured frame rate data, the optimal settings depend on the target resolution and refresh rate. At 1920x1080, all settings provide average frame rates above 500 FPS, which exceeds the refresh rate of most monitors. The Ultra preset at 500 FPS is the lowest but still extremely smooth, so users with 1080p displays can safely use Ultra settings without any performance concerns. The Medium preset at 563 FPS with a minimum of 478 FPS provides a good balance, but there is no practical reason to lower settings at this resolution given the high frame rates.

At 2560x1440, the High preset at 417 FPS and Ultra at 338 FPS both offer excellent experiences. The Ultra setting provides a 17.2% reduction in frame rate compared to High, but the absolute numbers are still far above typical display refresh rates. For users with 1440p monitors running at 240 Hz, the Ultra preset's 338 FPS average is sufficient, while the High preset at 417 FPS provides additional headroom. The Low preset at 508 FPS is unnecessary unless the user prioritizes maximum possible frame rates for competitive play, but the visual quality loss is not justified given the high performance of Ultra.

At 3840x2160, the choice of settings has a more noticeable impact. The Ultra preset averages 191 FPS, which is still very high but may be below the refresh rate of some premium 4K monitors with 240 Hz panels. The High preset at 236 FPS provides a 23.6% improvement over Ultra and is the recommended choice for 4K gaming if the user wants to stay above 240 FPS. The Medium preset at 267 FPS offers even more headroom at the cost of some visual fidelity. The Low preset at 293 FPS is the fastest but sacrifices significant visual quality. For most users, the High preset at 4K represents the best balance of visual quality and performance, delivering 236 FPS average with no reported minimum frame rate issues. The Medium preset is a strong alternative for those who prioritize frame rate stability, as it is the only setting at 4K with reported minimum and maximum values, showing a range of 227 to 307 FPS.
