Roblox

The Intel Core i5-11400F paired with the NVIDIA GeForce GTX 1070 ranks 1525th out of 1800 tested combinations for Roblox, placing it in the lower-middle tier of the database. This position is surprisingly modest given the hardware's raw capability, but it reflects the unique demands of Roblox's engine, which often favors single-thread performance and specific driver optimizations over sheer multi-core muscle. The CPU holds a percentile rank of 75 against all processors, yet the GPU's percentile of 51 against all graphics cards drags the overall combo down. In practical terms, this pairing is not a top-tier Roblox machine, but it is far from inadequate; the data shows it delivers playable frame rates at every tested setting, which is more than can be said for many lower-ranked configurations.

How This Combo Ranks

The combo's 1525th-place finish out of 1800 combinations is a clear signal that this hardware pairing is not optimized for Roblox's specific workload. The CPU, while solid in general compute tasks, sits in a strange middle ground here. Its nearest rivals in aggregate benchmark scores—the AMD Ryzen 7 5700U, Intel Core i7-1260P, Intel Core Ultra 7 164U, and Intel Core i5-1240U—are all within a 0.2% delta of its average score of 17181, yet those are mobile or low-power parts. This suggests that the i5-11400F's desktop-class performance is being neutralized by something in the Roblox pipeline, likely the GPU's age or the game's engine quirks. The GPU's nearest rivals, including the NVIDIA Quadro K4200 and GeForce GTX 880M, are significantly older or weaker, yet the GTX 1070 only leads them by margins of 0.7% to 1.7% in average benchmark score, indicating it is operating near the bottom of its expected performance envelope in this title.

What this ranking means for a user is that while the system will run Roblox, it will not excel at it. The data shows a 75th percentile CPU and a 51st percentile GPU, but the combination produces a rank that is below the 50th percentile of all combos. This discrepancy points to a bottleneck that is not purely computational. Roblox is known for being sensitive to draw calls and single-threaded physics, and the i5-11400F's single-thread score of 868 in 3DMark is respectable but not exceptional. The GTX 1070's 6.463 TFLOPS of FP32 performance is adequate, but its Pascal architecture lacks some modern optimizations. The result is a system that is better than its rank suggests for other games, but for Roblox specifically, the data indicates it is a mid-pack performer, not a leader.

GPU Role

The NVIDIA GeForce GTX 1070 is the defining component in this combo for Roblox. Its 8 GB of GDDR5 memory on a 256-bit bus provides 256.3 GB/s of bandwidth, which is more than sufficient for Roblox's asset streaming. The base clock of 1506 MHz and boost clock of 1683 MHz are modest by modern standards, but they are not the limiting factor in most scenarios. The GPU's 1920 shading units and 64 ROPs are capable of handling the game's blocky geometry, yet the data shows that the card is not being pushed to its limits in a way that would explain the low combo rank.

Instead, the GTX 1070's role here is that of a reliable but unspectacular workhorse. Its memory clock of 2002 MHz (effectively 8 Gbps) is fine for the game's textures, but the card's 51st percentile ranking against all GPUs suggests it is an average performer in the broader landscape. In Roblox, the GPU's performance seems to be capped by the engine's rendering path, which is not fully optimized for Pascal's architecture. The measured FPS at 1080p Ultra, 167.2 FPS, is high, but it is not dramatically higher than the 1440p High result of 137.7 FPS, indicating that the GPU is not the primary constraint at higher resolutions. The GTX 1070 is doing its job, but it is not the hero of this story; the CPU's interaction with the game's logic is likely the real bottleneck, explaining why the combo ranks so low despite the GPU's decent specifications.

Settings Recommendations

Based on the measured FPS data, the best experience for most users will come from the Medium preset at 1080p or 1440p, depending on the display. At 1080p Medium, the combo delivers 227.2 FPS, which is a massive jump from the 167.2 FPS at Ultra and only slightly below the 251.5 FPS at Low. This suggests that Medium offers a near-optimal balance, providing a smooth experience without the visual degradation of Low. The data shows that the difference between Low and Medium at 1080p is just 24.3 FPS, while the jump from Medium to Ultra costs 60 FPS, making Medium the sweet spot for competitive play.

For 4K users, the situation is different. The High preset at 3840x2160 yields 75 FPS, which is playable, but the Ultra preset drops to 59.5 FPS, which is borderline. The Low preset at 4K produces 93.8 FPS, which might be preferable for those prioritizing frame rate over visuals. However, the Medium preset at 87 FPS is a strong middle ground. Given that the GPU is not a top-tier part, the recommendation is to stick with Medium or High at 4K, as Ultra clearly strains the system. For 1440p, High is excellent at 137.7 FPS, but Medium at 151.2 FPS is even better, making it the recommended choice for high-refresh-rate monitors. The data consistently shows that Medium provides the best frame rate per setting level across all resolutions.

Measured FPS Breakdown

The measured FPS data reveals a clear pattern of diminishing returns as resolution and settings increase. At 1080p, the combo starts at 251.5 FPS on Low, drops to 227.2 FPS on Medium, 199.4 FPS on High, and bottoms out at 167.2 FPS on Ultra. This 84.3 FPS spread from Low to Ultra is significant, but even the lowest number is far above the 60 FPS threshold. At 1440p, the numbers are 169.3 FPS on Low, 151.2 FPS on Medium, 137.7 FPS on High, and 111.8 FPS on Ultra. The drop from Low to Ultra here is 57.5 FPS, showing a similar pattern but with a narrower absolute range.

At 4K, the performance takes a noticeable hit. The Low preset produces 93.8 FPS, Medium 87 FPS, High 75 FPS, and Ultra 59.5 FPS. The spread from Low to Ultra is 34.3 FPS, which is smaller in absolute terms but represents a larger percentage drop. The most striking observation is that the 4K Ultra result of 59.5 FPS is the only measured value below 60 FPS, indicating that this is the absolute limit of the combo's capability. The data shows that the transition from 1440p to 4K is where the system begins to struggle, with the 1440p High result of 137.7 FPS falling to 75 FPS at 4K High, a 45.5% reduction. This is a clear indication that the GPU is being pushed harder at higher resolutions, but the CPU is still keeping up, as evidenced by the relatively stable frame rates across settings at each resolution.

Resolution Scaling

The resolution scaling from 1080p to 4K demonstrates that the GTX 1070 is the primary limiting component as pixel count increases. From 1080p High (199.4 FPS) to 1440p High (137.7 FPS), the frame rate drops by 31%, which is roughly proportional to the increase in pixel count. However, from 1440p High to 4K High (75 FPS), the drop is 45.5%, which is steeper than the pixel count increase of 2.25 times would suggest. This nonlinear scaling indicates that the GPU is running out of memory bandwidth or fill rate at 4K, despite having 256.3 GB/s of bandwidth.

The CPU's role in this scaling is more subtle. The i5-11400F's boost clock of 4.40 GHz is sufficient to keep the GPU fed at lower resolutions, but at 4K, the GPU's workload becomes so heavy that the CPU's contribution diminishes. This is evident in the fact that the 4K Low result of 93.8 FPS is only 37% lower than the 1080p Low result of 251.5 FPS, whereas the 4K Ultra result of 59.5 FPS is 64% lower than the 1080p Ultra result of 167.2 FPS. The larger percentage drop at Ultra settings suggests that the GPU is not just rendering more pixels but also handling more complex shaders, which overwhelms its 6.463 TFLOPS of compute power. The data concludes that for this combo, 1080p and 1440p are the sweet spots, while 4K is only viable at Low or Medium settings, and even then, the frame rates are not ideal for competitive play.
