GPU Role

The Radeon RX 7800 XT is built on the RDNA 3.0 architecture and fabricated on a 5 nm process at TSMC. It contains 28,100 million transistors on a 346 mm² die, with a transistor density of 81.2M per mm². The GPU's memory subsystem consists of 16 GB of GDDR6 on a 256-bit bus, providing 624.1 GB/s of bandwidth. This large frame buffer and high bandwidth are directly relevant to Roblox, which can feature many user-generated textures and models. The 16 GB capacity ensures that even at 4K Ultra, there is no VRAM pressure, allowing the card to maintain consistent frame delivery.

Clock speeds are equally important. The base clock is 1295 MHz, the game clock is 2124 MHz, and the boost clock reaches 2430 MHz. The memory runs at 2438 MHz (19.5 Gbps effective). These clocks, combined with 3840 shading units, 240 TMUs, and 96 ROPs, produce a pixel rate of 233.3 GPixel/s and a texture rate of 583.2 GTexel/s. In Roblox, these specifications translate into the measured FPS: at 1080p Low, the average is 451.5 FPS, and at 4K Ultra it is 113.3 FPS. The GPU's 60 RT cores are present but not heavily utilized in this game, as Roblox does not rely on ray tracing.

The data suggests that the GPU is not the bottleneck at 1080p or 1440p. At those resolutions, the CPU's strong single-thread performance (Cinebench R23 single-core score of 4136) likely keeps the frame rate high. At 4K, the FPS drop across all settings shows the GPU becoming more dominant, but the RX 7800 XT still delivers 113.3 FPS at Ultra. This indicates that the card has ample headroom for Roblox's current rendering demands, and the 16 GB VRAM future-proofs against larger user-created worlds.

Resolution Scaling

The measured FPS shows a clear decline as resolution increases from 1920x1080 to 3840x2160. At High settings, the average drops from 364.8 FPS at 1080p to 242.5 FPS at 1440p and 136.2 FPS at 4K. Low settings follow the same pattern: 451.5, 300.3, and 169.5 FPS. Medium yields 412.6, 276.7, and 152.5 FPS, while Ultra produces 291.6, 196.8, and 113.3 FPS. The 4K averages are consistently lower than the 1080p averages, indicating that the GPU's fill rate and memory bandwidth become limiting factors as pixel count increases.

The gap between Low and Ultra also narrows at higher resolutions. At 1080p, Low is 451.5 FPS and Ultra is 291.6 FPS; at 4K, Low is 169.5 FPS and Ultra is 113.3 FPS. This suggests that the GPU's performance ceiling is approached at 4K, where even the lowest preset cannot exceed 169.5 FPS. The data points to a system that is CPU-bound at 1080p and GPU-bound at 4K. The CPU's high single-thread score (Cinebench R23 single-core 4136) helps maintain high frame rates at lower resolutions, while the GPU's 624.1 GB/s bandwidth and 233.3 GPixel/s pixel rate are taxed more heavily at 4K.

Settings Recommendations

Based on the measured FPS, all four presets are viable at every resolution. At 1080p, even Ultra delivers 291.6 FPS, which is more than enough for any display. At 1440p, Ultra still hits 196.8 FPS. At 4K, Ultra drops to 113.3 FPS, but that remains a high average. For users who prioritize visual quality, Ultra is the recommended preset across all resolutions, as it provides the highest fidelity without sacrificing playability. The lowest average across the entire measured set is 113.3 FPS, which occurs at 4K Ultra.

For those seeking maximum frame rates, Low is the best choice, offering 451.5 FPS at 1080p and 169.5 FPS at 4K. Medium and High provide intermediate trade-offs. The data shows that the RX 7800 XT can handle Roblox's Ultra preset without dropping below 113.3 FPS at 4K, so there is no need to compromise on settings for competitive play. At 4K, the choice between Low and Ultra involves a trade-off of 169.5 FPS versus 113.3 FPS, with Ultra offering better visuals. The consistent ordering of Low > Medium > High > Ultra at every resolution gives users a clear performance ladder to match their preferences.

Measured FPS Breakdown

The following table lists all measured average FPS values for the Ryzen 7 7700 + RX 7800 XT combination in Roblox.

|------------|----------|---------|

| 3840x2160 | High | 136.2 |

| 3840x2160 | Low | 169.5 |

| 3840x2160 | Medium | 152.5 |

| 3840x2160 | Ultra | 113.3 |

| 2560x1440 | High | 242.5 |

| 2560x1440 | Low | 300.3 |

| 2560x1440 | Medium | 276.7 |

| 2560x1440 | Ultra | 196.8 |

| 1920x1080 | High | 364.8 |

| 1920x1080 | Low | 451.5 |

| 1920x1080 | Medium | 412.6 |

| 1920x1080 | Ultra | 291.6 |

The data shows a consistent ordering: Low > Medium > High > Ultra at every resolution. The highest average is 451.5 FPS at 1080p Low, and the lowest is 113.3 FPS at 4K Ultra. The spread between Low and Ultra is largest at 1080p (451.5 vs 291.6) and smallest at 4K (169.5 vs 113.3). This pattern reinforces the resolution scaling analysis, indicating that the GPU becomes the limiting factor at higher pixel counts.
