Roblox

The Intel Core i5-11400F paired with the NVIDIA GeForce RTX 3050 4 GB delivers a compelling 1080p experience in Roblox, but the data reveals a clear shift in bottleneck behavior as resolution climbs. At 1920x1080 with Low settings, the combo hits 220 FPS average, which drops to 177 FPS at High settings — a 43 FPS difference that highlights how even a lightweight title like Roblox responds to graphical presets. Moving to 2560x1440, the spread tightens: Low produces 147.9 FPS, High drops to 115.8 FPS, and Ultra sits at 92.1 FPS. The 4K results tell the real story: 3840x2160 High yields only 64 FPS, while Low manages 80.6 FPS. The scaling from 1080p to 4K at High settings is steep — 177 FPS down to 64 FPS represents a 63.8% reduction, which points directly at the GPU becoming the limiting factor as pixel count rises. At 1080p, the frame rates are high enough that the CPU’s 6 cores and 12 threads can keep feeding the GPU, but by 4K the RTX 3050’s 4 GB VRAM and 128-bit memory bus are clearly the constraint.

Resolution Scaling

The measured rows show a predictable pattern: Roblox scales almost linearly with resolution until the GPU runs out of headroom. At 1080p, the gap between Low (220 FPS) and Ultra (140.6 FPS) is 79.4 FPS, indicating the GPU still has overhead and the CPU is doing meaningful work. At 1440p, that same Low-to-Ultra gap narrows to 55.8 FPS (147.9 vs 92.1), suggesting the GPU is starting to saturate. By 4K, the Low-to-Ultra spread is just 24.9 FPS (80.6 vs 55.7), which means the rendering pipeline is fully GPU-bound. The 4K Ultra result of 55.7 FPS is barely playable for smooth action, while 4K Low at 80.6 FPS is more comfortable. The data suggests that 1440p is the practical ceiling for this combo if you want to maintain frame rates above 90 FPS, and 1080p is where the hardware feels genuinely fast. The 4K numbers are usable only at Low or Medium settings, and even then, the 64 FPS at High shows how quickly performance degrades when the GPU’s 4 GB frame buffer is stressed by higher resolutions.

CPU Role

The Intel Core i5-11400F is a 6-core, 12-thread Rocket Lake part with a base clock of 2.60 GHz and a boost clock of 4.40 GHz. Its benchmark profile shows strong single-threaded performance — a 3dmark single-thread score of 868 and a passmark single-thread score of 2981 — which matters for Roblox’s often physics- and script-heavy worlds. The multi-threaded results are respectable for the class: cinebench R23 multicore hits 14372, and passmark multithread lands at 16908. In the context of this game, the CPU’s job is to maintain a steady frame delivery, and the data indicates it does so comfortably at 1080p, where the 220 FPS Low result is likely CPU-limited. The 3dmark 2-thread score of 1691 is particularly relevant because Roblox’s engine often relies on a few primary threads; a strong dual-core showing helps keep frame times consistent. The CPU’s 12 MB of shared L3 cache and 51.2 GB/s memory bandwidth provide enough data throughput for the game’s asset streaming, which is why the 1080p numbers remain high even at Ultra settings (140.6 FPS). As resolution increases, the CPU’s role diminishes — the 4K Low result of 80.6 FPS is still high, but the drop from 1080p Low (220 FPS) shows the GPU is now the gatekeeper. The i5-11400F is not the bottleneck in this pairing; it has enough headroom to push well beyond what the RTX 3050 can render at higher resolutions.

GPU Role

The NVIDIA GeForce RTX 3050 4 GB is the decisive component in this combo, and its 4 GB GDDR6 memory on a 128-bit bus with 192.0 GB/s bandwidth is the limiting factor at higher resolutions. The GPU’s base clock of 1545 MHz and boost clock of 1740 MHz, combined with 2048 shading units, deliver 7.127 TFLOPS of FP32 performance — enough for Roblox’s relatively simple shaders but not enough for heavy 4K workloads. The measured FPS data confirms this: at 1080p, the GPU is not fully utilized, as evidenced by the 220 FPS Low result, but at 4K, the 55.7 FPS Ultra result shows the GPU is maxed out. The VRAM capacity is the primary concern; Roblox’s procedural content and user-generated worlds can exceed 4 GB at high resolutions, causing texture swapping that drops frame rates. The 4K High result of 64 FPS, compared to 4K Medium at 78 FPS, suggests that the memory pressure is already affecting performance at High settings. The GPU’s 90 W TDP and 1x 6-pin power connector indicate it is a modestly powered card, but its real limitation is the narrow 128-bit bus, which restricts memory bandwidth precisely when 4K demands more data movement. The pixel rate of 55.68 GPixel/s and texture rate of 111.4 GTexel/s are adequate for 1080p and 1440p, but they fall short of sustaining high frame rates at 4K. The GPU’s 16 RT cores and 64 tensor cores are present but unused in Roblox, as the game does not employ ray tracing or DLSS, so those features do not influence the measured results.

Measured FPS Breakdown

At 1920x1080, the combo delivers its best performance: Low averages 220 FPS, Medium 196.3 FPS, High 177 FPS, and Ultra 140.6 FPS. The 79.4 FPS difference between Low and Ultra is significant, but even the lowest 1080p result is well above the refresh rate of most monitors. Moving to 2560x1440, the averages drop across the board: Low hits 147.9 FPS, Medium 134.5 FPS, High 115.8 FPS, and Ultra 92.1 FPS. The 1440p Ultra result remains playable, but it is the first setting where frame rates dip below 100 FPS. At 3840x2160, the numbers fall sharply: Low averages 80.6 FPS, Medium 78 FPS, High 64 FPS, and Ultra 55.7 FPS. The 4K Medium result is nearly identical to 4K Low (78 vs 80.6), which suggests that the GPU is so constrained that the preset choice has minimal impact until High settings trigger additional memory pressure. The 4K Ultra result of 55.7 FPS is the only measured row below 60 FPS, making it the least viable option. The data shows a consistent pattern: at 1080p, the CPU is the upper bound; at 1440p, the GPU begins to take over; at 4K, the GPU’s memory bandwidth and capacity are the sole limiting factors.

How This Combo Ranks

The combo ranks 1614 out of 1800 tested combinations for Roblox, placing it in the lower 10.3% of all pairings. This rank reflects the GPU’s modest 4 GB VRAM more than the CPU’s capabilities — the i5-11400F sits at the 75th percentile among all CPUs, which is a strong showing. The disconnect between the CPU’s high percentile and the combo’s low rank indicates that the RTX 3050 4 GB is the weak link in this pairing for Roblox specifically. The GPU’s percentile vs all GPUs is 50, meaning it is exactly average, but Roblox’s scaling with resolution and memory capacity punishes the 4 GB frame buffer more than other games might. The combo is not a top-tier performer, but it is not a failure either — it handles 1080p and 1440p admirably, which covers most practical use cases. The rank of 1614 suggests that many other combos with similar CPUs but larger VRAM GPUs would outperform it at higher resolutions, but for a budget-conscious build targeting 1080p, this pairing is functional. The CPU’s nearest rivals, such as the AMD Ryzen 7 5700U (deltaPct 0) and Intel Core i7-1260P (deltaPct -0.2), show that the i5-11400F is competitive with newer mobile parts, but the GPU’s lack of headroom keeps the overall combo off the leaderboard.

Settings Recommendations

For the best experience per the measured rows, 1920x1080 with High settings is the sweet spot — 177 FPS average provides a smooth, responsive feel with better visual fidelity than Low or Medium. If you prioritize maximum frame rates for competitive play, 1080p Low at 220 FPS is the clear choice, but the visual downgrade is noticeable. At 2560x1440, Medium settings at 134.5 FPS offer the best balance of quality and speed; High at 115.8 FPS is still excellent, but Ultra at 92.1 FPS incurs a 42.4 FPS penalty over Medium for marginal visual gains. For 4K, the data suggests sticking to Low (80.6 FPS) or Medium (78 FPS) — High at 64 FPS is playable but not ideal, and Ultra at 55.7 FPS should be avoided for any fast-paced action. The most practical recommendation is to run 1080p High for daily play, which gives a 177 FPS average and leaves GPU headroom for Roblox’s occasional frame spikes in complex worlds. If you have a 1440p monitor, Medium is the recommended preset, as it delivers 134.5 FPS while avoiding the performance cliff seen at Ultra. The 4K results are best treated as a bonus rather than a target; the hardware is capable of 4K, but only at lower presets, and the 64 FPS High result shows diminishing returns that favor Medium or Low.
