# Roblox — Intel Core i5-11400F + NVIDIA GeForce RTX 5070 Ti

This combination of an Intel Core i5-11400F and an NVIDIA GeForce RTX 5070 Ti delivers exceptionally high frame rates in Roblox across all tested settings and resolutions, with the data indicating that the CPU becomes the primary limiting factor at lower resolutions while the GPU scales predictably as resolution increases. The measured results place this combo at rank 406 out of 3711 tested combinations, putting it in the top 11% of all tested systems for this title.

Resolution Scaling

The frame rate progression from 1080p to 4K reveals a clear pattern of GPU-bound scaling at higher resolutions, but also exposes a significant CPU ceiling at lower settings. At 1080p with Low settings, the system achieves 606 FPS, which drops to 404 FPS at 1440p (a 33% reduction) and further to 229 FPS at 4K (a 43% reduction from 1440p). This scaling behavior suggests that at 1080p Low, the system is heavily CPU-limited, as the RTX 5070 Ti is capable of far higher frame rates than what the i5-11400F can feed it.

Moving to Medium settings, the pattern shifts slightly. At 1080p Medium, the average is 551 FPS, dropping to 368 FPS at 1440p (33% lower) and 208 FPS at 4K (43% lower from 1440p). The consistency of these percentage drops across Low and Medium settings indicates that the bottleneck remains largely CPU-side until 4K, where the GPU begins to take over as the limiting factor.

At High settings, the scaling becomes more pronounced. The 1080p result of 487 FPS drops to 325 FPS at 1440p (33% reduction) and then to 184 FPS at 4K (43% reduction from 1440p). This pattern continues the trend, but the absolute numbers are lower, suggesting that the increased graphical workload is starting to engage the GPU more meaningfully.

Ultra settings show the most significant resolution scaling. At 1080p Ultra, the system produces 395 FPS, which falls to 264 FPS at 1440p (33% reduction) and 149 FPS at 4K (44% reduction from 1440p). The 4K Ultra result of 149 FPS, while still very playable, demonstrates that this is where the GPU becomes the dominant constraint, with the RTX 5070 Ti's performance characteristics determining the final frame rate rather than the CPU.

The data indicates that across all settings, the percentage drop from 1080p to 1440p is consistently around 33%, while the drop from 1440p to 4K is consistently around 43-44%. This consistency suggests that Roblox's rendering workload scales in a predictable manner with resolution, and that the system's behavior is well-characterized by these measurements.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread processor based on the Rocket Lake architecture, manufactured on a 14 nm process. Its base clock of 2.60 GHz and boost clock of 4.40 GHz provide the computational foundation for this system's performance in Roblox. The CPU's cache configuration includes 80 KB of L1 per core, 512 KB of L2 per core, and 12 MB of shared L3 cache, which is relevant for a game like Roblox that often involves many small objects and scripts.

In synthetic benchmarks, the i5-11400F achieves a Cinebench R23 multicore score of 14340 and a single-core score of 2024, indicating strong per-thread performance that is beneficial for Roblox's often single-threaded physics and scripting workloads. The 3DMark scores show a progression from 868 in single-thread to 5652 in max-threads, demonstrating that the CPU scales reasonably well with additional threads, though the single-thread performance is what matters most for many Roblox scenarios.

The CPU's percentile ranking of 71 against all CPUs places it in the upper range of processors, and its average benchmark score of 17177 puts it in close competition with the AMD EPYC 7H12 (17120, 0.3% higher), Intel Core i5-12450H (17239, 0.4% lower), AMD Ryzen 3 PRO 8300G (17278, 0.6% lower), and Intel Core Ultra 7 164U (17074, 0.6% higher). These near-neighbor results suggest that the i5-11400F's overall compute capability is well-balanced for its class.

In Roblox specifically, the CPU's role is most evident at lower resolutions where frame rates exceed 500 FPS. At 1080p Low, the 606 FPS result is likely constrained by the CPU's ability to process game logic and issue draw calls, rather than the GPU's rendering capacity. The fact that increasing resolution at Low settings reduces frame rates by roughly one-third at each step while increasing settings at the same resolution also reduces frame rates suggests that both CPU and GPU contribute to the final result, but the CPU becomes relatively more important at lower graphical loads.

The CPU's 12 threads provide ample parallelism for Roblox's background tasks, and the 4.40 GHz boost clock ensures responsive single-threaded performance. The data shows that this CPU does not fully saturate the RTX 5070 Ti's capabilities at lower resolutions, as evidenced by the relatively small frame rate differences between Low and Medium settings at 1080p (606 vs 551 FPS, only 9% apart).

GPU Role

The NVIDIA GeForce RTX 5070 Ti is a Blackwell 2.0 architecture GPU built on TSMC's 5 nm process, featuring 45,600 million transistors on a 378 mm² die. Its 16 GB of GDDR7 memory on a 256-bit bus provides 896.0 GB/s of bandwidth, which is more than sufficient for Roblox's texture and geometry requirements. The GPU's 8960 shading units, 280 TMUs, and 96 ROPs deliver substantial raw compute throughput, with FP32 performance rated at 43.94 TFLOPS.

The GPU's clock speeds include a base of 2295 MHz and a boost of 2452 MHz, with memory operating at 1750 MHz (28 Gbps effective). These specifications place the RTX 5070 Ti in the 86th percentile of all GPUs, with an average benchmark score of 49957. Its nearest rivals in benchmark performance include the AMD Radeon RX Vega 64 (50001, 0.1% higher), Intel Arc A550M (49737, 0.4% lower), AMD Radeon RX 6900 XT (50951, 2% higher), and AMD Radeon RX 6800 XT (48477, 3.1% lower).

In Roblox, the GPU's role becomes progressively more important as resolution and settings increase. At 4K Ultra, the 149 FPS result is the most GPU-intensive configuration tested, and the GPU's 16 GB of VRAM is never a constraint given Roblox's modest memory footprint. The GPU's passmark G3D score of 32974 and directx 11 score of 300 indicate strong DirectX 11 performance, which is relevant since Roblox primarily uses that API.

The GPU's performance in Roblox is characterized by its ability to maintain very high frame rates even at 4K. At 4K High, the 184 FPS result demonstrates that the GPU can handle Roblox's rendering load at UHD resolutions without difficulty. The scaling from 1440p to 4K at each settings level shows a consistent 43-44% reduction, which is typical of a GPU-bound scenario where pixel count doubles but frame rate does not halve due to other bottlenecks.

The RTX 5070 Ti's 70 RT cores and 280 tensor cores are not specifically relevant to Roblox's current rendering pipeline, but they ensure future compatibility as the game evolves. The GPU's 896.0 GB/s memory bandwidth is more than adequate for Roblox's asset streaming, and the 16 GB capacity provides headroom for any future content updates.

Settings Recommendations

Based on the measured frame rates, the optimal settings depend heavily on the target resolution and display refresh rate. At 1080p, all settings produce frame rates well above 300 FPS, with even Ultra delivering 395 FPS. This means that at 1080p, Ultra settings provide the best visual quality without any meaningful performance compromise, as 395 FPS exceeds the refresh rate of virtually all monitors.

At 1440p, the situation is similar. Ultra settings deliver 264 FPS, which is still extremely high and suitable for high-refresh-rate displays. The difference between High (325 FPS) and Ultra (264 FPS) at 1440p is 19%, which is a noticeable performance cost, but the absolute numbers remain so high that Ultra is arguably the best choice for most users, particularly those with 144Hz or 165Hz monitors.

At 4K, the settings recommendation becomes more nuanced. Ultra delivers 149 FPS, which is still above 144Hz, but High delivers 184 FPS (24% higher). For users with 144Hz 4K displays, Ultra is viable, but for those with 240Hz displays, High provides a more comfortable margin. Medium at 4K delivers 208 FPS, offering an additional 13% over High, which may be preferable for competitive play.

The Low settings at each resolution provide the highest frame rates (606 FPS at 1080p, 404 FPS at 1440p, 229 FPS at 4K), but the visual quality trade-off is substantial. The data suggests that Medium settings provide a good balance, with 551 FPS at 1080p, 368 FPS at 1440p, and 208 FPS at 4K, representing only 9-10% reductions from Low at each resolution while offering noticeably improved visuals.

For the best overall experience per the measured rows, Ultra at 1080p or 1440p offers the highest visual fidelity without sacrificing playability, while at 4K, High or Medium settings are recommended depending on whether visual quality or frame rate headroom is prioritized.
