Roblox

Roblox, a sandbox title that has been live since 2006, remains surprisingly demanding at high settings and resolutions due to its user-generated content complexity. For the combination of the Intel Core i5-12400F and the NVIDIA GeForce RTX 2070 SUPER, the measured performance data reveals a system that is exceptionally capable for this title, offering high frame rates across the board. The benchmark results indicate a configuration where the GPU becomes the primary scaling factor at higher resolutions, while the CPU provides a robust foundation that prevents bottlenecking even at 1080p. This analysis breaks down the measured FPS data to understand the role each component plays in delivering the final experience.

Resolution Scaling

The performance drop from 1080p to 4K with this hardware configuration is significant and consistent with expectations for a mid-range to high-end pairing. At Low settings, the average frame rate falls from 339 FPS at 1920x1080 to 128 FPS at 3840x2160, representing a 62% decrease in performance as the resolution increases. This substantial drop is the clearest indicator that the rendering load is shifting heavily onto the GPU, as the number of pixels to be rendered quadruples from 1080p to 4K, directly impacting the fill-rate demands.

A similar pattern emerges at Ultra settings, where the average FPS declines from 221 at 1080p to 83 at 4K. This 62% reduction in frame rate across the extreme ends of the resolution spectrum highlights that the RTX 2070 SUPER is the limiting component in this scenario. The data suggests that while the GPU is powerful enough to push high frame rates at 1080p and 1440p, the 4K resolution, even for a less graphically intensive title like Roblox, begins to saturate the GPU's capabilities, particularly with higher quality presets that increase shader and texture complexity.

The scaling between 1440p and 4K is also telling. At High settings, the average FPS drops from 182 at 2560x1440 to 103 at 3840x2160, a 43% reduction. In contrast, the drop from 1080p to 1440p at the same High preset is from 272 FPS to 182 FPS, a 33% reduction. This non-linear scaling indicates that as resolution increases, the GPU's pixel processing capabilities become a more dominant constraint, whereas at lower resolutions, the frame rate is likely being limited by other factors, such as game engine draw call overhead, which the CPU must handle.

The minimum FPS data available for Medium settings offers additional insight into resolution scaling. At 4K, the minimum FPS is recorded at 99 FPS, compared to 175 FPS at 1440p and 262 FPS at 1080p. This shows that not only do average frame rates drop, but the consistency of frame delivery also suffers at higher resolutions, with the gap between average and minimum FPS widening. This fluctuation can be perceived as stutter, suggesting that while the average performance is playable at 4K, the experience is smoother at 1440p and below.

CPU Role

The Intel Core i5-12400F, with its 6 cores and 12 threads, provides a solid foundation for Roblox. The benchmark data shows a single-thread score of 909 in 3dmark and a multi-thread score of 5912 in 3dmark_max_threads, indicating strong per-core performance that is essential for game logic and physics. In a sandbox game where user-generated scenes can have complex script interactions, this single-thread capability is often more critical than raw multi-core throughput, ensuring that the game's primary simulation thread does not become a bottleneck.

The CPU's boost clock of 4.40 GHz, combined with a base clock of 2.50 GHz, allows it to dynamically scale performance based on workload. For Roblox, which may not utilize all 12 threads effectively, the high boost clock is advantageous for maintaining high frame rates in less parallelized tasks. The 18 MB of shared L3 cache also helps by storing frequently accessed game data, reducing latency and improving responsiveness in complex scenes.

Looking at the nearest rivals for the CPU, the i5-12400F is positioned closely with the AMD Ryzen 5 7535HS, with a negligible deltaPct of 0. This suggests that in general synthetic benchmarks, the two are equivalent, but the i5-12400F's desktop-oriented design with higher sustained power limits likely gives it an advantage in prolonged gaming sessions. Its performance in this Roblox configuration, particularly at 1080p where the CPU has more influence on the final frame rate, demonstrates that it is not holding back the RTX 2070 SUPER, as the average FPS reaches up to 339 at Low settings.

The data suggests that the CPU's role is to provide a stable, high-frequency platform that can feed the GPU with enough data to maintain high frame rates. At 1080p, the difference between Low and Ultra settings is 118 FPS (339 vs 221), which shows that even when the GPU load is relatively light, the system is not constrained by the processor. This indicates that the i5-12400F is a capable partner for the RTX 2070 SUPER in this title, allowing the GPU's performance to be the primary variable in the final output.

GPU Role

The NVIDIA GeForce RTX 2070 SUPER is the primary driver of frame rate changes across different settings and resolutions in this test. With 8 GB of GDDR6 memory on a 256-bit bus, providing a bandwidth of 448.0 GB/s, the GPU has ample resources for Roblox's texture and geometry data, even at 4K Ultra settings. The benchmark results show that the GPU is the determining factor in scaling performance, as evidenced by the significant FPS drops when moving to higher resolutions.

The GPU's boost clock of 1770 MHz and its 2560 shading units are key to its performance. The data shows a clear hierarchy in FPS based on settings at each resolution, which is directly attributable to the GPU's workload. For example, at 1440p, the average FPS ranges from 226 at Low settings to 148 at Ultra settings. This 78 FPS spread demonstrates how the GPU's processing units are tasked with more complex shading and effects as the preset quality increases, directly impacting the final frame rate.

The RTX 2070 SUPER's position relative to its rivals, such as the Intel Arc B570 with a deltaPct of -1.3, indicates that it is a competitive performer in its class. However, the data for this specific game suggests that its capabilities are best utilized at 1080p and 1440p, where it can achieve very high frame rates. At 4K, the average FPS of 103 on High settings is still smooth, but the GPU is clearly working harder, as shown by the 45 FPS difference between High and Ultra settings at that resolution. This indicates that the GPU's memory bandwidth and compute resources become a limiting factor at 4K, particularly when pushing the highest quality presets.

Furthermore, the GPU's 40 RT cores and 320 tensor cores are present, though Roblox does not typically leverage ray tracing or DLSS, so their impact on these results is minimal. Instead, the raw rasterization performance, represented by the 9.062 TFLOPS of FP32 compute, is what drives the frame rates seen in the data. The GPU's sustained performance across the board shows that it is well-matched to the i5-12400F at 1080p and 1440p, but at 4K, it becomes the clear bottleneck, preventing the system from reaching the same high frame rates seen at lower resolutions.

Settings Recommendations

Based on the measured FPS data, the optimal experience for this hardware configuration balances visual quality with high and consistent frame rates. At 1920x1080, all settings presets deliver excellent performance, with even Ultra settings averaging 221 FPS. For users with high refresh rate monitors, the Medium preset at 1080p, averaging 308 FPS, offers a significant boost over Ultra while maintaining a very smooth experience, and the data shows a minimum FPS of 262, indicating good consistency.

For 2560x1440, the High preset at 182 FPS is an excellent choice, providing a substantial visual upgrade over Medium while still delivering frame rates that are well above the threshold for smooth gameplay. The Ultra preset at 148 FPS is also viable for those who prioritize visual fidelity, but the 34 FPS drop from High may not be worth it for the marginal graphical improvement. The data suggests that High is the sweet spot at this resolution, as it maintains high averages without the risk of noticeable frame drops.

At 3840x2160, the High preset at 103 FPS is the recommended choice for a balance of quality and performance. The Ultra preset at 83 FPS is playable, but the average frame rate is significantly lower, and the lack of minimum FPS data for Ultra suggests potential inconsistency. The Medium preset at 116 FPS, with a recorded minimum of 99 FPS, is the best option for those who prioritize frame rate stability at 4K, as it stays well above the 60 FPS threshold and offers a more consistent experience. The Low preset at 128 FPS is an option for competitive play, but the visual compromise is substantial.

Overall, the data indicates that the best experience per the measured rows is Medium at 4K, High at 1440p, and either Medium or Ultra at 1080p depending on the user's refresh rate and preference for visual effects. The Medium preset consistently provides a high minimum FPS, indicating better frame pacing and a more stable experience across all resolutions.

How This Combo Ranks

The combination of the Intel Core i5-12400F and the NVIDIA GeForce RTX 2070 SUPER ranks 2139 out of 3711 tested combos for this game. This places it in the lower-middle portion of the database for Roblox, which is interesting given the high absolute frame rates measured. This ranking suggests that the database includes many more powerful and recent combinations, particularly those with newer GPUs, that can push even higher frame rates in this CPU-light game.

This ranking is likely influenced by the fact that Roblox can be heavily CPU-bound at lower resolutions, and the i5-12400F, while capable, is not at the top end of the performance spectrum. The RTX 2070 SUPER, while a strong GPU, is also not the fastest available, as indicated by its percentileVsAllGpus of 65. The combination's rank reflects that while it can achieve very high frame rates, there are many other tested configurations that can achieve even higher numbers, particularly at 1080p where the CPU becomes more relevant.

The percentileVsAllCpus for the i5-12400F is 73, and the percentileVsAllGpus for the RTX 2070 SUPER is 65. This shows that the CPU is relatively stronger than the GPU when compared to their respective market segments. However, in this game, the combo's rank of 2139 out of 3711 (42nd percentile) suggests that the GPU's performance is a more significant factor in the overall ranking, as the game scales heavily with resolution and settings, which are GPU-dependent tasks. While the absolute performance is high, the ranking indicates that it is not a top-tier combo for this title, but rather a solid mid-range performer.
