A: The CPU achieves a 3dmark_single_thread score of 868 and a passmark_single_thread score of 2981. These scores are relevant because Roblox's performance appears heavily dependent on single-threaded CPU performance, as evidenced by the high frame rates at low resolutions.

GPU Role

The NVIDIA GeForce RTX 5090 is a powerhouse, featuring 32 GB of GDDR7 memory on a 512-bit bus, delivering 1.79 TB/s of bandwidth. Its 21760 shading units, 680 TMUs, and 176 ROPs provide immense raw processing power, with the chip rated for 104.8 TFLOPS of FP32 compute. The card's boost clock is 2407 MHz, and it holds the 94th percentile among all GPUs in the database.

In Roblox, the GPU's role becomes less about raw compute and more about maintaining high frame rates without becoming a bottleneck. The data shows that even at 4K Ultra, the GPU delivers 180.9 FPS, suggesting it has ample headroom. The memory capacity of 32 GB is far beyond what Roblox requires, but the massive bandwidth ensures that texture streaming and draw calls at high resolutions are handled without issue. The GPU's performance metrics, such as a passmark_g3d score of 39650, place it in a tier where it can push frame rates to levels that are limited by other components.

Interestingly, the GPU's closest rival, the RTX 5090 D, has a nearly identical average score with a deltaPct of 0.1%. This suggests that the specific model of RTX 5090 used here is not uniquely optimized for Roblox; rather, the game's performance ceiling is dictated by the CPU and the engine's rendering pipeline.

Resolution Scaling

The measured FPS data reveals a clear scaling pattern across resolutions. At 1080p Low, the system achieves 682 FPS, which is the highest recorded frame rate. Moving to 1440p Low, the FPS drops to 494.5, a 27.5% decrease. At 4K Low, the FPS falls further to 281.1, representing a 43.2% drop from 1440p. This scaling indicates that as resolution increases, the GPU's workload grows, but the frame rates remain exceptionally high.

At Ultra settings, the scaling is more pronounced. From 1080p Ultra at 481.2 FPS, the frame rate drops to 321.7 FPS at 1440p (a 33.1% decrease) and then to 180.9 FPS at 4K (a 43.8% decrease from 1440p). The data suggests that the GPU is still not fully saturated at 1080p, as the jump from Low to Ultra only reduces FPS by 29.4% (from 682 to 481.2). This implies that at lower resolutions, the CPU is the primary limiting factor, while at 4K, the GPU begins to take on a more significant role, yet still maintains frame rates above 180 FPS.

The frame rate drops between resolutions are larger than what would be expected if the GPU were the sole bottleneck, indicating that the CPU's single-threaded performance is constraining the system's ability to feed the GPU with enough draw calls to fully utilize its potential.

How This Combo Ranks

This specific combination of the Intel Core i5-11400F and NVIDIA GeForce RTX 5090 achieves a rank of 38 out of 1800 tested combos in Roblox. This places the system in the top 2.1% of all combinations, which is a strong showing given the CPU's mid-range positioning. The rank suggests that while the GPU is top-tier, the CPU's performance is sufficient to avoid being a major bottleneck in this game.

The CPU's average benchmark score of 17181 places it in the 75th percentile of all CPUs, with its nearest rivals being the AMD Ryzen 7 5700U and Intel Core i7-1260P, both within 0.2% of its score. This indicates that the i5-11400F is a capable processor, but not the absolute fastest available. The fact that this combo still ranks 38th overall suggests that Roblox is not heavily dependent on multi-core CPU performance, and that the combination of a strong single-threaded CPU and an extremely powerful GPU is sufficient to reach near the top of the leaderboard.

The 38th rank out of 1800 combos implies that there are only 37 other configurations that perform better in this game. Given the GPU's 94th percentile ranking, it is likely that those higher-ranked combos feature CPUs with even stronger single-threaded performance, as the GPU is already among the best available.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor based on Rocket Lake architecture, with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. It has 12 MB of shared L3 cache and a 14 nm process node. Its single-threaded performance is highlighted by a 3dmark_single_thread score of 868 and a passmark_single_thread score of 2981. These scores are critical for understanding Roblox's performance, as the game's engine appears to be heavily reliant on single-threaded CPU performance.

The CPU's multi-threaded performance is also solid, with a cinebench_r23_multicore score of 14372 and a geekbench_multicore score of 7579. However, the data shows that in Roblox, the single-threaded performance is the more relevant metric. At 1080p Low, the system achieves 682 FPS, which is likely near the maximum frame rate that the CPU can feed to the GPU. The fact that increasing resolution to 4K only reduces FPS to 281.1 at Low settings suggests that the CPU is still able to provide enough draw calls to keep the GPU busy, but the frame rate ceiling is set by the CPU's single-thread speed.

The CPU's percentileVsAllCpus of 75 indicates that it is faster than 75% of all CPUs tested. This is a respectable position, but it also means that there are CPUs with higher single-threaded performance that could potentially unlock even higher frame rates in Roblox. The data implies that while the i5-11400F is not the bottleneck at 4K Ultra, it is likely the limiting factor at 1080p Low, where the GPU is barely stressed.

Measured FPS Breakdown

At 1920x1080, the measured average FPS ranges from 481.2 at Ultra settings to 682 at Low settings. The Medium preset delivers 659.1 FPS, while High achieves 594.2 FPS. These figures show that at 1080p, the system is capable of exceeding 480 FPS even at the highest settings, with the gap between Low and Ultra being 200.8 FPS.

Moving to 2560x1440, the frame rates remain high but show a clear reduction. Low settings produce 494.5 FPS, Medium delivers 448 FPS, High achieves 394 FPS, and Ultra drops to 321.7 FPS. The difference between Low and Ultra at 1440p is 172.8 FPS, which is smaller than at 1080p, indicating that the GPU is beginning to exert more influence.

At 3840x2160, the frame rates are still impressive. Low settings yield 281.1 FPS, Medium delivers 256.1 FPS, High achieves 226.2 FPS, and Ultra drops to 180.9 FPS. The gap between Low and Ultra at 4K is 100.2 FPS, which is the smallest of the three resolutions. This data shows a consistent trend: as resolution increases, the absolute frame rates decrease, and the relative impact of graphics settings on performance diminishes.

The settings scaling within each resolution is also noteworthy. At 1080p, the jump from Low to Medium is only 22.9 FPS, but the jump from High to Ultra is 113 FPS. This suggests that the Ultra preset is significantly more demanding than High, likely due to increased draw distances and effects that stress the CPU as well as the GPU.

Settings Recommendations

For the best experience according to the measured data, the High preset at 1440p offers an excellent balance, delivering 394 FPS. This is significantly higher than the 60-144 Hz refresh rates of most monitors, providing ample headroom for smooth gameplay. The Ultra preset at 1440p, with 321.7 FPS, is also viable and offers the maximum visual fidelity without dropping below 300 FPS.

At 4K, the High preset at 226.2 FPS is the recommended choice for users with high-refresh-rate 4K displays. The Ultra preset at 180.9 FPS is still playable and provides the best image quality, but the 45.3 FPS difference between High and Ultra at this resolution may not justify the visual gains for some users. The Medium preset at 256.1 FPS at 4K offers a middle ground, but the data suggests that High is the sweet spot for 4K gaming.

For competitive play where frame rate is paramount, the Low preset at 1080p delivers 682 FPS, which is the highest recorded frame rate in the dataset. However, for most users, the Medium preset at 1080p, with 659.1 FPS, provides a better visual experience with only a 22.9 FPS penalty compared to Low. The data indicates that this system is so powerful that even the most demanding settings at 4K produce frame rates far above what is needed for a smooth experience, making the choice of settings more about visual preference than performance necessity.
