The AMD Radeon RX Vega 56 comes in at 37507, representing a 0.4 percent gap, while the NVIDIA GeForce RTX 4080 Mobile scores 38135, which is 1.3 percent higher. The AMD Radeon PRO W6400 trails by 1.3 percent with a score of 37157. These figures suggest that in a purely synthetic sense, a system using an RTX 4070 would behave nearly identically to one using a Tesla P4 or RX Vega 56, at least in terms of raw compute potential, though the architectural differences would manifest differently in actual game workloads.

CPU and GPU Roles

The measured FPS data reveals a clear pattern regarding which component bears more weight in Roblox at different resolutions. At 1920x1080, the frame rates are extraordinarily high, with the Low preset achieving 503.2 FPS, Medium at 457 FPS, High at 402.2 FPS, and Ultra at 324.5 FPS. The scaling between presets at this resolution shows that lowering settings from Ultra to Low yields a 178.7 FPS increase, or roughly a 55 percent improvement. This suggests that at 1080p, the GPU has ample headroom and the CPU's single-thread performance becomes the limiting factor, as the i5-12400's strong single-core capabilities allow it to feed the RTX 4070 efficiently.

Moving to 2560x1440, the frame rates remain high but begin to show more GPU influence. The Low preset delivers 335.5 FPS, Medium 307.2 FPS, High 270.6 FPS, and Ultra 218.1 FPS. The delta between Low and Ultra here is 117.4 FPS, a 53.7 percent reduction, which is proportionally similar to the 1080p scaling. However, the absolute numbers are lower across the board, indicating that the increased pixel count is placing additional load on the GPU's rendering pipeline. At 3840x2160, the GPU's role becomes even more pronounced. Low settings produce 190.2 FPS, Medium 171 FPS, High 155.9 FPS, and Ultra drops to 123.9 FPS. The gap between Low and Ultra at 4K is 66.3 FPS, a 53.3 percent decrease, maintaining the same proportional scaling but at significantly lower absolute values.

The data implies that Roblox is largely CPU-bound at lower resolutions, where the i5-12400's six cores and 12 threads provide sufficient processing power to push frame rates past 400 FPS. As resolution increases, the RTX 4070's workload grows, and the GPU becomes the more dominant factor in determining final performance. The consistent proportional scaling between presets across all resolutions suggests that Roblox's rendering engine scales predictably with GPU load, while the CPU maintains a steady baseline of performance.

Measured FPS Breakdown

At 1920x1080, the combination achieves its highest frame rates. The Low preset records an average of 503.2 FPS, which represents the ceiling of what this system can deliver in Roblox.

Every setting at this resolution clears the 60 FPS threshold by a substantial margin, with even the most demanding configuration delivering more than five times the minimum playable frame rate.

At 2560x1440, performance remains robust but shows a clear step down from 1080p. The Low preset averages 335.5 FPS, Medium 307.2 FPS, High 270.6 FPS, and Ultra 218.1 FPS. The scaling from Low to Ultra at this resolution represents a 117.4 FPS drop, which is proportionally similar to the 1080p results but with lower absolute numbers. The system still maintains a comfortable margin above the 60 FPS threshold, with the Ultra preset delivering more than triple the required frame rate.

At 3840x2160, the system continues to deliver high performance. The Low preset averages 190.2 FPS, Medium 171 FPS, High 155.9 FPS, and Ultra 123.9 FPS. Even at 4K resolution with the most demanding settings, the average frame rate remains more than double the 60 FPS target. The data shows a clear relationship between resolution and performance, with each step up in resolution reducing frame rates by roughly 30 to 40 percent, but the absolute numbers remain far above playable thresholds throughout.

The Verdict

The benchmark data unequivocally indicates that this PC can run Roblox with exceptional performance at all tested configurations. According to the verdict by resolution, every single resolution and preset combination clears the 60 FPS playable threshold. At 3840x2160, the best settings are Ultra, which achieves an average of 123.9 FPS, more than double the playable threshold. At 2560x1440, Ultra settings also represent the best configuration, delivering 218.1 FPS, which is over three times the minimum requirement.
