Roblox

The Intel Core i5-11400F paired with the NVIDIA GeForce RTX 5080 delivers exceptional performance in Roblox, far exceeding the 60 FPS playability threshold at every resolution and preset combination recorded in the database. Across all tested settings, this combination produces average frame rates that range from 170.4 FPS at 4K Ultra to 681 FPS at 1080p Low, indicating that the system is never remotely constrained in this title. The benchmark data shows a consistent pattern: the GPU provides massive headroom, and even the most demanding settings at the highest resolution remain nearly three times above the playability threshold. For users targeting high refresh rate displays, this configuration supports 240 Hz and even 360 Hz class monitors at 1440p and 1080p with ease. The following sections detail the measured performance across every resolution and settings preset, how this combo ranks among all tested combinations, answers to common questions, and a clear verdict on what this hardware can achieve in Roblox.

Measured FPS Breakdown

The database contains measured average frame rates for twelve distinct scenarios, covering three resolutions and four graphics presets. Minimum and maximum frame rate values are not recorded for this game, so the analysis relies on average FPS data. At 1920x1080, the lowest resolution tested, performance is extremely high across all presets. The Low preset produces 681 FPS, the highest average recorded for this combination. Medium follows at 620.3 FPS, High at 545.4 FPS, and Ultra at 445.6 FPS. The scaling between presets is consistent, with each step up in quality reducing performance by a meaningful but moderate margin. From Low to Ultra, the average FPS drops by roughly 35%, yet even the slowest 1080p preset remains over seven times the 60 FPS threshold. This resolution is clearly GPU-bound in a way that allows the RTX 5080 to operate at very high utilization, with the i5-11400F providing enough single-thread performance to keep frame delivery smooth.

Moving to 2560x1440, the same pattern holds but with lower absolute numbers. Low records 454.3 FPS, Medium 414.4 FPS, High 366.9 FPS, and Ultra 297 FPS. The relative drop from Low to Ultra is about 35%, similar to the 1080p scaling. At this resolution, the workload increases noticeably on the GPU, but the combination still delivers frame rates that are far beyond what any standard display can reproduce. The data indicates that 1440p Ultra maintains an average of 297 FPS, which is nearly five times the playability threshold. Even in the most demanding scenario at this resolution, there is no risk of dropping below 60 FPS in typical gameplay.

At 3840x2160, commonly known as 4K, the performance remains very strong. Low produces 255.9 FPS, Medium 236.7 FPS, High 204.5 FPS, and Ultra 170.4 FPS. The scaling from Low to Ultra is slightly steeper here, with Ultra being about 33% slower than Low. This is expected as the pixel throughput demands increase dramatically at 4K. However, even the slowest recorded preset, 4K Ultra, delivers an average of 170.4 FPS, which is well above the 60 FPS threshold and still sufficient for high refresh rate gaming on 144 Hz or 165 Hz monitors. The gap between 1080p and 4K at the same preset is substantial, with 4K Ultra being about 62% slower than 1080p Ultra, but the absolute performance remains outstanding.

The data reveals no settings preset at any resolution falls below 170 FPS on average. This indicates that the primary limitation in Roblox is not the hardware but rather the game's own frame rate caps or engine behavior at such high speeds. The i5-11400F, with its boost clock of 4.40 GHz and 12 threads, provides sufficient CPU throughput for the game's single-thread-heavy workloads, while the RTX 5080's 56.28 TFLOPS FP32 compute and 960.0 GB/s memory bandwidth handle the rendering effortlessly. Across all twelve measured points, the lowest average FPS is 170.4 at 4K Ultra, and the highest is 681 at 1080p Low. There is no scenario in the database where this combo approaches the 60 FPS playability threshold.

How This Combo Ranks

In the database rankings for Roblox, this specific combination of the Intel Core i5-11400F and NVIDIA GeForce RTX 5080 holds the 192nd position out of 3711 tested combos. This places it in the top 5.2% of all configurations recorded for this game. The rank reflects the combined contribution of both the CPU and GPU, and given that Roblox is often sensitive to single-core CPU performance, the i5-11400F's strong showing in synthetic benchmarks helps explain this high placement. The CPU's single-thread score in Cinebench R23 is 2024, and its PassMark single-thread score is 2981, both indicating solid per-core capability. The GPU's PassMark G3D score of 36565 is a major contributor to the combo's standing, as the RTX 5080 provides an enormous amount of rendering power.

The percentile data reinforces this picture. The i5-11400F sits at the 71st percentile among all CPUs in the database, while the RTX 5080 sits at the 87th percentile among all GPUs. When combined in Roblox, the pairing performs better than either component's individual percentile might suggest on its own, because the game is not heavily multithreaded and benefits from the GPU's raw speed. The combo rank of 192 out of 3711 means that 3519 tested combinations deliver lower average FPS in this game, while 191 deliver higher. This is a strong result, though not the absolute top, as some combinations with newer or higher-clocked CPUs and equally powerful GPUs may edge ahead in specific scenarios.

The CPU's average benchmark score is 17177, and the GPU's average benchmark score is 56083, but these aggregate numbers do not directly translate to Roblox performance. Instead, the measured FPS data provides the most relevant comparison. At 1080p Ultra, the combo produces 445.6 FPS, which is a strong indicator of its ranking position. The fact that the combo ranks 192nd rather than higher is likely due to the CPU's moderate position relative to top-end processors. In Roblox, extremely high frame rates can be limited by CPU single-thread performance even when the GPU is vastly overqualified. The i5-11400F, while capable, is not the fastest single-threaded CPU in the database, and this may cap performance in the lowest resolution and least demanding presets where the GPU is not the bottleneck.

The Verdict

This PC can run Roblox with exceptional ease at every resolution and preset combination recorded in the database. The verdict by resolution is unambiguous: at 3840x2160, all four presets (Low, Medium, High, Ultra) are playable, with the best settings being Ultra at an average of 170.4 FPS. At 2560x1440, all four presets are playable, with Ultra delivering 297 FPS. At 1920x1080, all four presets are playable, with Ultra delivering 445.6 FPS. The 60 FPS playability threshold is cleared by a factor of at least 2.8 at the weakest point (4K Ultra) and by a factor of over 11 at the strongest point (1080p Low).

The data indicates that this combination is overkill for Roblox in the traditional sense. The RTX 5080's immense compute capability, combined with the i5-11400F's solid single-thread performance, creates a system that never drops below 170 FPS on average. For competitive players who prioritize frame rate over visual fidelity, the Low preset at 1080p yields 681 FPS, which exceeds the refresh rate of virtually all consumer monitors. For players who want maximum visual quality, the Ultra preset at 4K still provides 170.4 FPS, which is smooth on any 144 Hz display and even usable on 165 Hz panels.

The only practical consideration is that Roblox may have internal frame rate limits that prevent the hardware from reaching its full potential in some scenarios. The measured data, however, reflects actual recorded performance, and the averages are all far above what is needed for a responsive experience. There is no scenario in the database where this combo fails to meet the 60 FPS threshold, and the margin is so large that even future updates to the game that increase system requirements would need to be extremely demanding to challenge this hardware.

Similar Performance Alternatives

For the Intel Core i5-11400F, the nearest rivals in the database are the AMD EPYC 7H12, the Intel Core i5-12450H, the AMD Ryzen 3 PRO 8300G, and the Intel Core Ultra 7 164U. The AMD EPYC 7H12 has an average score of 17120, which is 0.3% lower than the i5-11400F's 17177, making it effectively equivalent in synthetic benchmarks. The Intel Core i5-12450H scores 17239, which is 0.4% higher, meaning it would behave nearly identically in Roblox. The AMD Ryzen 3 PRO 8300G scores 17278, which is 0.6% higher, again a negligible difference. The Intel Core Ultra 7 164U scores 17074, which is 0.6% lower. Any of these CPUs paired with the same GPU would produce very similar frame rates in Roblox, as the game is not heavily dependent on multi-core scaling.

For the NVIDIA GeForce RTX 5080, the nearest rivals are the AMD Radeon 8060S, the AMD Radeon RX 6750 GRE 12 GB, the AMD Radeon Pro W5700X, and the AMD Radeon RX 9070 GRE. The AMD Radeon 8060S scores 55757, which is 0.6% lower than the RTX 5080's 56083, indicating near-identical performance. The AMD Radeon RX 6750 GRE 12 GB scores 55698, which is 0.7% lower, also very close. The AMD Radeon Pro W5700X scores 54828, which is 2.3% lower, a small but slightly more noticeable gap. The AMD Radeon RX 9070 GRE scores 57367, which is 2.2% higher, meaning it would deliver marginally better average FPS in Roblox. When combined with a CPU in the same performance class as the i5-11400F, these GPU alternatives would produce average FPS figures within a few percentage points of the measured values for the RTX 5080 in this game.

The practical implication is that users with any of these rival components would experience essentially the same gameplay in Roblox. The differences in synthetic benchmark scores are all under 3%, and the game's performance is so far above the playability threshold that these variations would not be perceptible. The combo rank of 192 out of 3711 is specific to the i5-11400F and RTX 5080 pairing, but swapping in one of these rivals would likely shift the rank by only a handful of positions, if at all.

Best Settings per Resolution

At 3840x2160, the most demanding preset that stays at or above 60 FPS is Ultra, which delivers an average of 170.4 FPS. This is the highest quality setting available in the database, and it clears the playability threshold by a factor of 2.8. Lower presets at this resolution produce higher frame rates (High at 204.5 FPS, Medium at 236.7 FPS, Low at 255.9 FPS), but there is no need to sacrifice quality for performance, as Ultra is already far above the threshold.

At 2560x1440, the most demanding preset is also Ultra, with an average of 297 FPS. This is nearly five times the playability threshold, so users can enable every visual option without concern. The High preset records 366.9 FPS, Medium 414.4 FPS, and Low 454.3 FPS, but Ultra is the recommended choice for maximum quality at this resolution.

At 1920x1080, the most demanding preset is Ultra, delivering an average of 445.6 FPS. This is over seven times the playability threshold, making it the clear recommendation for players who want the best visuals. The High preset records 545.4 FPS, Medium 620.3 FPS, and Low 681 FPS, but all of these are well above what any display can reproduce. For competitive play, the Low preset at 681 FPS offers the highest possible frame rate, but for general use, Ultra at 445.6 FPS provides the best balance of image quality and speed.

In summary, the best settings for each resolution are Ultra at 4K (170.4 FPS), Ultra at 1440p (297 FPS), and Ultra at 1080p (445.6 FPS). There is no scenario where lowering settings is necessary to maintain playability, as every preset in the database clears the 60 FPS threshold by a wide margin.
