Roblox

This analysis covers the AMD Ryzen 9 7900X paired with the Intel Arc B370 running Roblox, a sandbox game released on 2006-08-31. The recorded measurements place this combination at rank 3417 out of 3711 tested configurations in the database. The verdict is clear: this system handles Roblox at 1080p and 1440p with all presets above 60 FPS, but it fails to reach 60 FPS at 4K at any setting.

Similar Performance Alternatives

The Ryzen 9 7900X posts an average benchmark score of 53288, placing it in the 91st percentile among all CPUs. Its nearest rivals are tightly clustered. The AMD EPYC 7313P scores 53206, a 0.2% gap. The Intel Xeon Phi 7290 scores 53469, which is 0.3% higher. The Intel Xeon 634 scores 52974, 0.6% lower. The Intel Core i7-14700F scores 53620, 0.6% higher. In CPU-bound scenarios, these four parts would deliver nearly identical results. For Roblox, the CPU is not the limiting factor, so swapping among these would not meaningfully change frame rates.

The 7900X also records a Cinebench R23 multi-core score of 29300 and a single-core score of 2016.5, along with a Passmark multi-thread score of 51406 and a single-thread score of 4238. These scores reinforce its position at the 91st percentile. The nearest rivals all fall within a 1.2 point spread in average score, meaning any of them would behave similarly in CPU-heavy tasks. The EPYC 7313P is a server part, while the Core i7-14700F is a desktop chip, yet their aggregate scores are nearly indistinguishable from the 7900X.

The Intel Arc B370 has an average benchmark score of 1184, placing it in the 5th percentile of all GPUs. Its nearest rivals are all within a 1.4% band: the ATI Mobility Radeon HD 5570 scores 1186 (0.2% higher), the ATI Radeon HD 5770 scores 1190 (0.5% higher), the AMD Radeon HD 7650M scores 1192 (0.7% higher), and the AMD FirePro M2000 scores 1168 (1.4% lower). In GPU-bound workloads, the Arc B370 behaves essentially identically to these legacy cards. Since Roblox is GPU-bound at the tested settings, users with any of these GPUs would see similar performance. The only benchmark recorded for the Arc B370 is 3DMark Steel Nomad DX12 with a score of 1184, which matches the average.

CPU and GPU Roles

The data shows that the GPU is the dominant factor in Roblox performance across all resolutions and presets. The CPU is a 12-core, 24-thread Zen 4 part with a 91st percentile standing, while the GPU sits at the 5th percentile. When resolution scales from 1080p to 4K, average FPS drops steeply: at Ultra, from 101 FPS at 1080p to 67 FPS at 1440p and 38 FPS at 4K. This scaling pattern is characteristic of a GPU-bound workload. The CPU's headroom is evident from its benchmark scores: Geekbench single-core 2617 and multi-core 19267, and Cinebench R23 multi-core 29300. Even at 1080p Low, where CPU load is highest relative to GPU, the system reaches 154 FPS, far above the 60 FPS threshold. The GPU's throughput limits (48.00 GPixel/s pixel rate and 96.00 GTexel/s texture rate) align with the observed FPS ceiling.

At a fixed resolution, preset changes produce moderate FPS shifts. At 4K, the difference between Low and Ultra is 20 FPS (58 vs 38). At 1440p, it is 36 FPS (103 vs 67). At 1080p, it is 53 FPS (154 vs 101). This widening gap at lower resolutions indicates that the GPU has more headroom to express preset differences when pixel count is reduced. The CPU, with its high single-thread and multi-thread scores, never appears as the bottleneck: the FPS scales almost entirely with GPU load. The Arc B370's 25 W TDP and integrated graphics design further confirm that it is a low-power part, and the recorded frame rates reflect that constraint.

Measured FPS Breakdown

The following table lists the recorded average, minimum, and maximum FPS for each resolution and preset. Where min or max were not recorded, the cell is blank.

| Resolution | Settings | Avg FPS | Min FPS | Max FPS |

| 3840x2160 | High | 47 | | |

| 3840x2160 | Low | 58 | | |

| 3840x2160 | Medium | 53 | 45 | 61 |

| 3840x2160 | Ultra | 38 | | |

| 2560x1440 | High | 83 | | |

| 2560x1440 | Low | 103 | | |

| 2560x1440 | Medium | 94 | 80 | 108 |

| 2560x1440 | Ultra | 67 | | |

| 1920x1080 | High | 124 | | |

| 1920x1080 | Low | 154 | | |

| 1920x1080 | Medium | 140 | 119 | 161 |

| 1920x1080 | Ultra | 101 | | |

At 4K, none of the four presets reach the 60 FPS threshold. Low is the highest at 58 FPS, followed by Medium at 53, High at 47, and Ultra at 38. The only recorded min and max at this resolution is Medium, ranging from 45 to 61 FPS, meaning some frames do exceed 60 but the average stays below. At 1440p, all four presets clear 60 FPS. Ultra averages 67 FPS, High 83, Medium 94, and Low 103. Medium at 1440p ranges from 80 to 108 FPS, showing consistent performance. At 1080p, all presets are well above 60 FPS. Ultra averages 101, High 124, Medium 140, and Low 154. Medium at 1080p ranges from 119 to 161 FPS, with the minimum still nearly double the playable threshold.

The Verdict

This system can run Roblox at 1920x1080 and 2560x1440 with all presets exceeding the 60 FPS playable threshold. At 1080p, the best playable setting is Ultra with an average of 101 FPS. At 1440p, the best playable setting is also Ultra, averaging 67 FPS. At 3840x2160, no preset reaches 60 FPS: Low averages 58, Medium 53, High 47, and Ultra 38. The database verdict confirms this: 4K has no playable settings, while 1440p and 1080p list all four presets as playable. The Ryzen 9 7900X, with a launch MSRP of $549, provides ample CPU performance, but the Arc B370's 5th percentile GPU standing prevents 4K playability in Roblox. The system ranks 3417 out of 3711 tested combinations, which places it in the lower portion of the database, but for this particular game the 60 FPS target is met at the two most common resolutions.

Best Settings per Resolution

At 3840x2160, no setting reaches 60 FPS. The closest is Low at 58 FPS, which still misses the threshold. At 2560x1440, the most demanding preset that stays at or above 60 FPS is Ultra, with an average of 67 FPS. At 1920x1080, the most demanding preset that stays at or above 60 FPS is also Ultra, with an average of 101 FPS. These results mean that users targeting 60 FPS should play at 1080p or 1440p with Ultra settings, and should avoid 4K entirely. The measured FPS at Ultra for 1440p (67) leaves only 7 FPS of headroom above the threshold, so users who prefer a larger margin could drop to High at 83 FPS or Medium at 94 FPS. At 1080p, Ultra at 101 FPS provides a comfortable buffer, and even High at 124 FPS or Medium at 140 FPS are available for those who want extra smoothness. The data does not support any 4K preset for this combination.
