Roblox

Roblox is not typically the first title that comes to mind when discussing high-end hardware, yet the benchmark data for the Intel Core i9-14900K and NVIDIA GeForce RTX 4070 SUPER combination reveals a fascinating case study in system scaling. The measured frame rates are exceptionally high across the board, but the pattern of performance degradation from 1080p to 4K tells a compelling story about which component is doing the heavy lifting. This analysis examines the measured FPS data, component specifications, and ranking context to understand what this pairing achieves in a sandbox environment.

Resolution Scaling

The data shows a dramatic and consistent drop in average frame rates as resolution increases, which is a clear indicator of the GPU becoming the primary limiting factor at higher resolutions. At 1080p with Ultra settings, the combo produces 366.8 FPS, but this falls to 243.7 FPS at 1440p and further to 139.6 FPS at 4K. This represents a performance decrease of approximately 34% from 1080p to 1440p, and another 43% drop from 1440p to 4K. The scaling pattern suggests that at 1080p, the system is likely constrained by the CPU’s ability to feed the GPU, while at 4K, the GPU’s rendering workload takes precedence.

The Low settings preset provides the clearest view of this dynamic. At 1080p Low, the system achieves 559.3 FPS, which is the highest measured result in the entire dataset. At 1440p Low, the frame rate drops to 373.6 FPS, and at 4K Low, it falls to 210.8 FPS. The drop from 1080p to 1440p is 33%, while the drop from 1440p to 4K is 44%. This pattern mirrors the Ultra settings trajectory, reinforcing that the GPU’s pixel throughput is the dominant constraint at higher resolutions, regardless of the graphical preset.

The implications are clear: this system has enough CPU headroom to push extremely high frame rates at lower resolutions, but the RTX 4070 SUPER’s 192-bit memory bus and 504.2 GB/s bandwidth become the bottleneck as pixel count increases. The 4K Ultra result of 139.6 FPS, while still smooth, shows the largest performance penalty, indicating that the GPU is working at its limits with the most demanding settings at that resolution.
