Roblox

The Intel Core i7-14700KF paired with the NVIDIA GeForce RTX 5070 Ti delivers exceptionally high frame rates in Roblox across all tested settings and resolutions. The data shows this combination ranks 163rd out of 1800 tested combos for this game, placing it in the top percentile of systems. With average FPS figures ranging from 150.3 at 4K Ultra to 616.2 at 1080p Low, this hardware is far beyond what Roblox typically demands, making the limiting factor almost entirely dependent on the CPU at lower resolutions and the GPU at higher ones.

Resolution Scaling

The measured FPS data reveals how the performance burden shifts as resolution increases. At 1080p, the system produces massive frame counts: 616.2 FPS on Low, 560.5 on Medium, 497.1 on High, and 398.3 on Ultra. Moving to 1440p drops those figures to 414, 373.4, 327.7, and 267.4 respectively. At 4K, the numbers fall further to 231.6 on Low, 213.3 on Medium, 189.6 on High, and 150.3 on Ultra.

The scaling pattern is telling. From 1080p to 1440p, the average FPS drop across all settings is roughly 30-33%, which is a typical resolution penalty. However, from 1440p to 4K, the drop is more severe, averaging around 42-44%. This larger drop at 4K indicates the GPU is starting to become the primary constraint, though even at 4K Ultra the system still holds 150.3 FPS, which is far above playable thresholds.

The relationship between settings and resolution is also consistent. At every resolution, the Low preset yields the highest FPS, followed by Medium, then High, with Ultra producing the lowest numbers. The delta between Low and Ultra grows with resolution: at 1080p the gap is 217.9 FPS (616.2 vs 398.3), at 1440p it is 146.6 FPS (414 vs 267.4), and at 4K it narrows to 81.3 FPS (231.6 vs 150.3). This narrowing gap suggests that as resolution climbs, the GPU workload dominates and the settings menu has relatively less impact on overall performance.

CPU Role

The Intel Core i7-14700KF is a 20-core, 28-thread processor based on Raptor Lake architecture, with a base clock of 3.40 GHz and a boost clock of 5.60 GHz. Its benchmark results show strong single-threaded performance with a Cinebench R23 single-core score of 6290 and a Geekbench single-core score of 2972. Multi-threaded results are equally impressive: Cinebench R23 multi-core hits 44557 and Passmark multithread reaches 52425.

The CPU's percentile ranking of 96 against all CPUs means it outperforms 96% of processors on the market. Its nearest rivals include the Intel Core i7-14700K with an average score of 70074 and a deltaPct of 0, meaning they are effectively tied. The AMD Ryzen 9 9950X scores 70420, putting the 14700KF just 0.4% behind, while the Intel Xeon Platinum 8270 scores 71056, a 1.3% lead. The AMD EPYC 9115 trails at 69887, 0.3% behind.

In Roblox, the CPU's role is most apparent at 1080p where frame rates exceed 600 FPS. At those levels, the game logic and physics simulation become the bottleneck, not the graphics pipeline. The high boost clock of 5.60 GHz and strong single-thread performance are what enable these extreme frame rates. The 33 MB of shared L3 cache also helps maintain consistent performance during complex game scenarios with many active objects and scripts.

GPU Role

The NVIDIA GeForce RTX 5070 Ti features 16 GB of GDDR7 memory on a 256-bit bus, delivering 896.0 GB/s of bandwidth. Its boost clock runs at 2452 MHz, and the card offers 8960 shading units, 280 TMUs, and 96 ROPs. The GPU's Passmark G3D score of 32974 places it in the 87th percentile of all GPUs.

Its nearest rival is the NVIDIA GeForce RTX 4080 with an identical average score of 52085 and a deltaPct of 0. The AMD Radeon RX 7700S scores 52505 (0.8% higher), while the NVIDIA RTX A1000 scores 50826 (2.5% lower) and the AMD Radeon Pro W6600M scores 53414 (2.5% higher). This places the RTX 5070 Ti in a competitive tier where small percentage differences separate cards.

The GPU's 16 GB VRAM is generous for Roblox, which is not a VRAM-intensive title. The 896.0 GB/s bandwidth and 43.94 TFLOPS FP32 performance are more than sufficient for the game's rendering demands. At 4K resolution, the GPU becomes the limiting factor, as evidenced by the larger FPS drops from 1440p to 4K compared to the 1080p to 1440p transition. The card still manages 150.3 FPS at 4K Ultra, showing it has headroom even at the most demanding tested configuration.

Settings Recommendations

Based on the measured FPS rows, the High preset at 1440p offers the best balance for most users. It delivers 327.7 FPS, which is more than double the refresh rate of typical high-end monitors. The Ultra preset at 1440p drops to 267.4 FPS, still far above any practical display refresh rate, but the visual gains from Ultra over High are marginal in a game like Roblox while the performance cost is significant.

For 4K displays, the High preset at 189.6 FPS is the recommended choice. The Medium preset at 213.3 FPS provides a slight performance boost, but High offers better visual fidelity without dipping below 150 FPS. The Ultra preset at 4K, at 150.3 FPS, is still playable but leaves less headroom for frame time spikes in busy scenes.

The Low preset at any resolution produces the highest frame rates, but the visual quality trade-off is substantial. Since even the Ultra preset at 4K maintains 150.3 FPS, there is no practical need to drop to Low settings. The data indicates that Medium at 4K (213.3 FPS) or High at 1440p (327.7 FPS) are the sweet spots, depending on whether the user prioritizes resolution or frame rate headroom.
